102 conversions of the class-wide return object to the specific type on
103 component assignments).
105 * sem_ch6.adb (Check_Return_Subtype_Indication): Suppress the error
106 about a type mismatch for a class-wide function with a return object

350 access level of the Etype of Prev rather than Prev_Orig, because the
351 original exression has not always been analyzed.

430 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
431 Orig_Prev to Prev in the case where the actual is N_Function_Call or
432 N_Identifier. This was interfering with other cases that are rewritten
433 as N_Identifier, such as allocators, resulting in passing of the wrong
434 accessibility level, and based on testing this code is apparently no
435 longer needed at all.
437 2008-08-01 Ed Schonberg <schonberg@adacore.com>
439 * sem_ch4.adb (Analyze_One_Call): Handle complex overloading of a

2526 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
2527 convention from its base type, do not set the type to that of integer,

2594 New local subprogram Is_Valid_Remote_Object_Type, replaces
2595 Is_Recursively_Limited_Private.

2606 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
2607 Is_Remote_Call_Interface to identify RACW types in a stable and
2608 consistent way. We used to rely in this predicate on the privateness of
2609 the designated type and its ancestors, but depending on the currently
2610 visible private parts, this caused false negatives. We now uniformly
2611 rely on checks made at the point where the RACW type is declared.

2625 Add missing escaping of all-caps word 'CPP' in error messages.
2626 (Build_Discriminated_Subtype): Do not inherit representation clauses
2627 from parent type if subtype already carries them, because they are
2628 inherited earlier during derivation and already include those that may
2629 come from a partial view.
2631 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
2632 Check the declarations of a subprogram body for proper deferred

2667 operation of an RACW stub type (these primitives are only executed
2668 through dispatching, never through static calls).
2669 (Collect_Interps): When only one interpretation has been found, set N's
2670 Entity and Etype to that interpretation, otherwise Entity and Etype may
2671 still refer to an interpretation that was ignored by Add_One_Interp,
2672 in which case would end up with being marked as not overloaded but with
2673 an Entity attribute not pointing to its (unique) correct interpretation.
2675 2008-05-20 Ed Schonberg <schonberg@adacore.com>
2678 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

2732 equivalent representation, but has the advantage of allowing
2733 compilation of this file under 64 bits platforms.

7039 and those of the target interface primitive.
7040 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
7041 Timed_Entry_Call): Analyze the triggering statement as the first step of
7042 the processing. If this is a dispatching select, postpone the analysis
7043 of all select statements until the Expander transforms the select. This

7045 replicated some of the select statements. In case the Expander is
7046 disabled, perform regular analysis.
7047 (Check_Triggering_Statement): New routine.
7048 (Analyze_Requeue): Exclude any interpretations that are not entries when
7049 checking overloaded names in a requeue. Also test type conformance for

7642 a predefined entity (as happens for array index types), the line is set
7644 Add support for parsing multiple array index types info, or
7645 multiple inherited interfaces info. This information cannot be stored
7646 in Xref_Entity_Record, which only supports a single instance of Tref_*,
7647 and is therefore stored in the list of references instead. It has a

7662 Dismukes). After this patch there is no need to perform any
7663 additional management on these nodes in Expand_Interface_Actuals.
7665 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
7666 that handles use of 'Access and 'Unchecked_Access applied to
7667 actuals covering interface types. Such code is now
7668 centralized in Expand_N_Attribute_Reference.
7670 2007-10-15 Ed Schonberg <schonberg@adacore.com>
7672 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
7673 of tagged types whose ultimate ancestor is a CPP type.

7704 * vx_stack_info.c: New file.
7706 * i-forbla-unimplemented.ads: New file.
7708 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
7709 for unsupported configurations; use it on VMS targets instead of the

7712 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
7713 used by VxWorks targets to have access to task-specific data and be
7714 able to extract the stack boundaries for stack checking.
7715 Use system-vms-ia64.ads on ivms.

7758 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
7759 association for an access component, add an association with null as
7760 the expression. Remove testing for array subtypes and the setting in
7761 that case of Ctyp to the array component type, which prevented proper
7762 inclusion of an association for null-initialized arrays. Collapse
7763 condition that tests for array subtypes into just a test of
7764 Is_Partially_Initialized_Type (which already covers arrays anyway).
7766 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

7918 type of file_info_ptr parameter.
7919 If mapped location support is enabled, create the isomorphic mapping
7920 between source files and line maps.
7921 (Sloc_to_locus): If mapped location support is enabled, translate
7922 source location into mapped location.

7950 Add a section on leap seconds control along with two entities used to
7951 enable and disable leap seconds support. The array Leap_Second_Times is
7952 now constant and contains hard time values pre-generated. Remove
7953 all elaboration code used to populate the table of leap seconds.

8013 2007-09-26 Javier Miranda <miranda@adacore.com>
8014 Eric Botcazou <ebotcazou@adacore.com>
8017 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
8018 indirection added to the HT_Link component of the TSD. This is required
8019 to statically allocate the TSD.
8022 Minor reordering of the declarations in the private part. Required to
8023 add a level of indirection to the contents of the TSD component HT_Link.
8024 This is required to statically allocate the TSD.
8026 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
8027 Is_Statically_Allocated set from constant objects.
8028 Do not make exported constants created by the compiler volatile.
8029 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
8032 * trans.c (Identifier_to_gnu): For constants, unshare initializers
8033 before returning them.
8035 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
8036 public part of the package.
8037 (Make_DT): Move HT_Link component out of the TSD record. For this
8038 purpose Make_DT now declares a separate object that stores the
8039 HT_Link value, and initializes the TSD component with the address
8040 of this new object. The addition of this level of indirection is
8041 required to statically allocate the TSD because the TSD cannot
8042 have variable components.
8043 (Expand_Interface_Conversion): Improve the expanded code.
8044 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
8046 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
8047 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
8048 if we are building static dispatch tables then we must not generate
8049 extra code to register the primitive because the dispatch table will
8050 be built at the end of the library package; otherwise we notify that
8051 we cannot build the static dispatch table.
8053 2007-09-26 Robert Dewar <dewar@adacore.com>
8055 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

8070 for thunks associated with interface types.
8072 * einfo.ads: Improve documentatation of Is_Internal
8073 (Is_Thunk): New attribute applicable to subprograms. True for thunks
8074 associated with interface types.
8075 Extensive comment fixes regarding flags that appear in all entities. The
8076 documentation is now consistent for all such flags (there were a number
8077 of errors in the documentation in this regard).
8079 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
8081 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
8082 of these procedures are passed a function call that already has
8083 build-in-place actuals (testing new flag
8084 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
8085 the case where processing continues.
8086 (Expand_Call): If the call is generated from a thunk body then we
8087 propagate the extra actuals associated with the accessibility
8088 level of the access type actuals.
8090 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
8091 of each extra formal of a protected operation to reference the
8092 corresponding extra formal of the subprogram denoted by the
8093 operation's Protected_Body_Subprogram.
8095 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
8096 N_Function_Call nodes.
8098 2007-09-26 Robert Dewar <dewar@adacore.com>
8100 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
8102 * debug.adb: Add d.s flag.
8104 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8106 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
8107 debug variable so that it won't be initialized when pragma
8108 Initialize_Scalars is in effect.
8110 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8112 * freeze.adb (Freeze_Entity): Remove check for preelaborable
8113 initialization of a full view. This is moved to
8114 Analyze_Package_Specification.
8116 * sem_ch7.adb (Analyze_Package_Specification): Add check for
8117 preelaborable initialization of a full view in entity loop.
8118 (Uninstall_Declarations): If entity is a use-visible compilation unit,
8119 its child units are use-visible only if they are visible child units.
8121 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
8122 whether an expression can be used within a type declaration that
8123 requires preelaborable init.
8124 (Check_Components): Replace inline code that does partial checking for
8125 preelaborable default expressions with call to
8126 Is_Preelaborable_Expression.
8127 (Has_Preelaborable_Initialization): In the case of a generic actual
8128 subtype, (that is, Is_Generic_Actual is True), return the result of
8129 applying Has_Preelaborable_Initialization to the generic actual's base
8132 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
8134 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
8135 call to Jan_1_Day _Of_Week to optimize its performance.
8136 (Is_Leap): Move the routine to the scope of Week_In_Year.
8137 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
8138 weekday on which January 1 falls of Year - 1 and Year + 1. This function
8139 avoids calling Time_Of and Split, thus making it more efficent.
8140 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
8142 * g-calend.ads (Week_In_Year): Change comment to reflect new
8145 2007-09-26 Emmanuel Briot <briot@adacore.com>
8147 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
8148 Command_Line): New types
8149 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
8150 support for defining how switches can be grouped on a command line (as
8151 is the case for -gnatw... for GNAT), and how simple switches can be
8152 used as aliases for more complex switches (-gnatwa is same as
8154 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
8155 (Start, Current_*): New subprograms
8156 Added support for parsing an array of strings in addition to the real
8158 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
8159 be moved from the body to the private part of the spec.
8160 (*): All subprograms now have an extra parameter with default value to
8161 specify which parser should be used. For backward compatibility, it
8162 defaults to parsing the command line of the application. They were also
8163 modified to properly handle cases where each of the argument does not
8164 start at index 1 (which is always true for Ada.Command_Line, but not
8165 when processing any Argument_List).
8166 (Free): New subprogram
8167 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
8168 Argument): New subprograms
8169 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
8170 special characters like ':', '=',... are now handled in a single place,
8171 which makes the code more extensible eventually.
8172 (Getopt, Full_Switch): When the switch was returned as part of the
8173 special character '*', make sure it is prepended by the switch character
8174 ('-' in general), so that the application knows whether "foo" or "-foo"
8175 was specified on the command line.
8177 2007-09-26 Florian Villoing <villoing@adacore.com>
8179 * g-dirope.adb (Remove_Dir): In case we are removing directories
8180 recursively, make sure that if an exception is raised during the
8181 processing, the current working directory is reset to its initial
8182 value before propagating the exception.
8184 2007-09-26 Vincent Celier <celier@adacore.com>
8186 * gnatbind.adb: If there are several ALI files specified and there is
8187 a main program to bind, the first ALI is expected to contain the main
8188 subprogram and the names of the binder generated files will be derived
8189 from the first ALI file name.
8190 (Gnatbind): Fix insertion character in invocation of Error_Msg
8192 2007-09-26 Vincent Celier <celier@adacore.com>
8194 * gnatcmd.adb (Check_Files): Do not include sources that have been
8195 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
8197 2007-09-26 Ed Schonberg <schonberg@adacore.com>
8199 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
8200 information about each of its index types, following the type
8201 reference for its component type.
8203 2007-09-26 Vincent Celier <celier@adacore.com>
8205 * make.adb: (Kill): New procedure (__gnat_kill imported)

8209 compilation processes.
8211 (Gnatmake): If project files are used, create the mapping of all the
8212 sources, so that the correct paths will be found.
8214 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
8216 2007-09-26 Vincent Celier <celier@adacore.com>
8218 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
8220 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
8221 Replace components Compiler_Min_Options and Binder_Min_Options with
8222 Compiler_Required_Switches and Binder_Required_Switches in record
8224 Remove components Default_Language and Config in Project_Tree_Data,
8227 * prj-attr.adb: New attributes Required_Switches (<language>) in
8228 packages Compiler and Binder.
8230 * prj-nmsc.adb: Major rewrite of the processing of configuration
8231 attributes for gprbuild. No impact on GNAT tools.
8233 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

8236 being extended, instead of a shallow copy.
8237 (Process_Project_Tree_Phase_1): New procedure

8239 (Process): Implementation now uses the two new procedures
8241 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
8242 from the project config, not the tree config that no longer exists.

8262 * sem_attr.adb (Analyze_Access_Attribute): Fix missing set of
8265 2007-09-26 Ed Schonberg <schonberg@adacore.com>
8267 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
8268 ancestor of the derived type, the operations are inherited from the
8269 primary dispatch table of the parent.
8270 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
8271 when the context is an explicit type conversion.
8273 2007-09-26 Ed Schonberg <schonberg@adacore.com>

8573 potentially be called.
8574 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
8575 body for 'Output when the type is abstract (only the creation of the
8576 body for 'Input is excluded when the type is abstract).
8577 (Stream_Operation_OK): Add an additional condition in the return
8578 statement, so that False will be returned for TTS_Stream_Input if the
8579 associated tagged type is an abstract extension. Add comments for
8581 (Expand_N_Object_Declaration): For the case of a shared passive
8582 variable, insert init proc call only after the shared variable
8583 procedures have been processed, because the IP call needs to undergo
8584 shared passive variable reference expansion, which requires these
8585 procedures to be available (and elaborated).

8597 type, retrieve its value from the aggregate itself, where it must have
8600 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
8601 to remove other spurious ambiguities on arithmetic operations involving
8602 literals and addresses, on systems where Address is a visible integer
8603 type, when the operator is called in functional notation.
8604 (Try_Primitive_Operation): Within an instance, a call in prefixed form
8605 is legal when the types match, even if the operation is currently
8608 2007-09-10 Ed Schonberg <schonberg@adacore.com>
8610 * sem_ch12.adb (Build_Local_Package): A formal package with no
8611 associations is legal if all formals have defaults. It is not

8730 (Write_Entity_Flags): Write the status of flag Is_Raised.
8731 (Is_Descendent_Of_Address): New entity flag, to simplify handling of

8753 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
8754 library-level package renaming, pass the declaration associated with
8755 the renaming's special debug variable to Qualify_Entity_Names to ensure
8756 that its encoded name is properly qualified.
8758 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
8759 occurring in the list of entities to qualify, and do not attempt to
8760 traverse an entity list in that case. Variables associated with
8761 ` library-level package renamings can now occur in the table.

8780 to include loop parameters.
8781 (Valid_Conversion): Avoid generation of spurious error message.

8785 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
8786 concatenations of string literals into a single literal, in order to
8787 avoid very deep recursion in the front end, which was causing stack
8790 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
8791 string, and the right operand is a string literal (the case of "" &
8792 "..."), optimize by avoiding copying the right operand -- just use the
8793 value of the right operand directly.
8795 * stringt.adb (Store_String_Chars): Optimize by growing the
8796 String_Chars table all at once, rather than appending characters one by
8798 (Write_String_Table_Entry): If the string to be printed is very long,
8799 just print the first few characters, followed by the length. Otherwise,
8800 doing "pn(n)" in the debugger can take an extremely long time.
8802 * sem_prag.adb (Process_Interface_Name): Replace loop doing
8803 Store_String_Char with Store_String_Chars.

8822 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
8823 flag, for effiency. It is called when analyzing arithmetic operators
8824 and also for actuals in calls that are universal_integers. The flag is
8825 set for the predefined type address, and for any type or subtype
8828 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
8829 Universal_Integer, when the formal is a descendent of address and the

8910 (Debug_Renaming_Declaration): Replace creation of an enumeration type
8911 and literal with creation of a variable of type

8925 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
8926 ancestor part given by an aggregate to test for an unchecked conversion,
8927 since this can occur in some cases when the ancestor part is a function
8928 call, and we don't want to fall into the recursive call to this
8929 procedure in that case.
8931 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
8932 stream attributes on limited types to account for user-specified
8933 attributes as well as whether Input (resp. Output) becomes available
8934 due to Read (resp. Write) being available for the type. Change Boolean
8935 variable to the more accurate name
8936 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
8937 double-"not" predicate at beginning of return statement to more
8938 understandable form.
8940 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
8941 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
8942 in a block statement and use that as the first statement of the
8943 expanded return rather than incorrectly using the handled sequence as
8944 the first statement.
8946 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
8947 operation, generate an explicit freeze node for it rather than
8948 generating extra formals, to ensure that gigi has the proper order of
8949 elaboration for anonymous subtypes in the signature of the subprograms.
8950 (Build_In_Place_Formal): Move assertion to beginning of loop.
8951 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
8952 applied to a function call (occurs for some cases of 'Input).

8954 applied to a function call (occurs for some cases of 'Input).
8956 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
8957 2005, generate an extended return statement enclosing the result object
8960 * freeze.adb (Freeze_Record_Type): Extend the current management of
8961 components that are access type with an allocator as default value: add
8962 missing support to the use of qualified expressions of the
8963 allocator (which also cause freezing of the designated type!)
8964 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
8965 dispatching operation, since extra formals may be needed by calls to
8966 build-in-place functions (such as stream 'Input).
8968 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
8969 formals for 'Constrained and accessibility level in the case of a
8970 predefined dispatching operation.
8972 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
8973 point, no need to find the parent node.
8975 2007-08-16 Javier Miranda <miranda@adacore.com>
8977 * exp_attr.adb (Attribute_Priority): Add missing support for entries
8980 2007-08-16 Javier Miranda <miranda@adacore.com>
8982 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
8983 is not really required and can introduce regression with the debugger.
8984 The original problem is fixed with the patch written for checks.adb.

8988 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

8996 Including_Non_Switch set to False.
8998 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
8999 parameter Including_Non_Switch, defaulted to True. When
9000 Including_Non_Switch is False, options that are not switches and
9001 appear as relative path are not converted to absolute paths.

9016 from the immediate ancestor of Main_Unit_Entity.
9017 (Install_Limited_Withed_Unit): Do not install the limited view of
9018 package P if P is reachable through an ancestor chain from package C
9019 and C also has a with clause for P in its body.
9020 (Has_Limited_With_Clause): New routine.
9021 (Has_With_Clause): New routine.
9023 2007-08-16 Ed Schonberg <schonberg@adacore.com>
9025 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
9026 generic for an enclosing instance is a global reference, even though
9027 its scope is the enclosing instance.
9029 2007-08-16 Gary Dismukes <dismukes@adacore.com>
9030 Javier Miranda <miranda@adacore.com>
9032 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

9050 Bob Duff <duff@adacore.com>
9051 Nicolas Setton <setton@adacore.com>
9053 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
9054 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
9055 the statement which is being resolved comes from a predefined library
9056 unit, all non-predefined library interpretations are skipped.
9057 (Resolve_Op_Concat): If string concatenation was folded in the parser,
9058 but the "&" is user defined, give an error, because the folding would
9061 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
9062 the parser has folded a long sequence of concatenations of string
9065 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
9066 and "JMP_BUF" variables as artificial.
9067 (N_String_Literal): Do not use alloca for very long string literals. Use

9120 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
9121 needed for access to concurrent record types generated by the expander.
9122 (Generate_Range_Check): When generating a temporary to capture the
9123 value of a conversion that requires a range check, set the type of the
9124 temporary before rewriting the node, so that the type is always
9125 properly placed for back-end use.
9126 (Apply_Float_Conversion_Check): Handle case where the conversion is
9128 (Get_Discriminal): Code reformatting. Climb the scope stack looking

9144 (Expand_N_Type_Conversion): Test for the case of renamings of access
9145 parameters when deciding whether to apply a run-time accessibility
9147 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
9148 aggregate code before allocator, and ahead of declaration for
9149 temporary, to prevent access before elaboration when the allocator is
9150 an actual for an access parameter.
9151 (Expand_N_Type_Conversion): On an access type conversion involving an
9152 access parameter, do not apply an accessibility check when the
9153 operand's original node was an attribute other than 'Access. We now
9154 create access conversions for the expansion of 'Unchecked_Access and
9155 'Unrestricted_Access in certain cases and clearly accessibility should
9156 not be checked for those.
9158 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
9159 includes a type conversion of a packed component that has been expanded,
9160 recover the original expression for the object, and use this expression
9161 in the post-call assignment statement, so that the assignment is made
9162 to the object and not to a back-end temporary.
9163 (Freeze_Subprogram): In case of primitives of tagged types not defined
9164 at the library level force generation of code to register the primitive
9165 in the dispatch table. In addition some code reorganization has been
9166 done to leave the implementation clear.
9167 (Expand_Call): When expanding an inherited implicit conversion,
9168 preserve the type of the inherited function after the intrinsic
9169 operation has been expanded.
9171 * exp_ch2.ads, exp_ch2.adb
9172 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
9173 of an entry formal appearing in an assignment statement does not assign
9175 (Expand_Current_Value): Instead of calling a routine to determine
9176 whether the prefix of an attribute reference should be optimized or
9177 not, prevent the optimization of such prefixes all together.
9179 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
9180 component whose prefix is known to be of an access type is an implicit
9181 dereference and does not assign to the prefix.

9184 Robert Dewar <dewar@adacore.com>
9186 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
9187 itype is visited, make an entry into table to link associated node and
9189 Add comments and correct harmless error in Build_NCT_Hash_Tables
9190 (Array_Aggr_Subtype): Associate each itype created for an index type to
9191 the corresponding range construct, and not to the aggregate itself. to
9192 maintain a one-to-one correspondence between itype and its associated
9193 node, to prevent errors when complex expression is copied.
9194 Fix mishandling of multiple levels of parens
9196 * sem_aggr.adb: Create a limited view of an incomplete type, to make
9197 treatment of limited views uniform for all visible declarations in a
9198 limited_withed package.
9199 (New_Copy_Tree): If hash table is being used and itype is visited,
9200 make an entry into table to link associated node and new itype.
9201 (Resolve_Record_Aggregate): Do not add an others box association for a
9202 discriminated record component that has only discriminants, when there
9203 is a box association for the component itself.

9252 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
9253 generation of a freezing node to ensure proper management of null
9254 excluding access types in the backend.
9255 (Create_Extra_Formals): Test base type of the formal when checking for
9256 the need to add an extra accessibility-level formal. Pass the entity E
9257 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
9258 originally being done in a couple of cases), to ensure that the
9259 Extra_Formals list gets set on the entity E when the first entity is
9261 (Conforming_Types): Add missing calls to Base_Type to the code that
9262 handles anonymous access types. This is required to handle the
9263 general case because Process_Formals builds internal subtype entities
9264 to handle null-excluding access types.
9265 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9266 functions that need it, even when not marked Requires_Overriding.
9267 Improve warnings for in out parameters
9268 (Analyze_Function_Return): Warn for disallowed null return
9269 Warn on return from procedure with unset out parameter
9270 Ensure consistent use of # in error messages
9271 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
9272 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
9273 the implicit conversion of the expression done for anonymous access
9274 types. This is required to generate the code of the null excluding
9275 check (if required).
9277 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
9278 A formal parameter is never publicly referenceable outside of its body.
9279 (Check_References): For an unreferenced formal parameter in an accept
9280 statement, use the same warning circuitry as for subprogram formal
9282 (Warn_On_Unreferenced_Entity): New subprogram, taken from
9283 Output_Unreferenced_Messages, containing the part of that routine that
9284 is now reused for entry formals as described above.
9285 (Goto_Spec_Entity): New function
9286 (Check_References): Do not give IN OUT warning for dispatching operation
9287 Improve warnings for in out parameters
9288 (Test_Ref): Check that the entity is not undefinite before calling
9289 Scope_Within, in order to avoid infinite loops.
9290 Warn on return from procedure with unset out parameter
9291 Improved warnings for unused variables

9294 Javier Miranda <miranda@adacore.com>
9295 Gary Dismukes <dismukes@adacore.com>
9297 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
9298 (Expand_N_Attribute_Reference): Further unify the handling of the
9299 three forms of access attributes, using common code now for all three
9300 cases. Add a test for the case of applying an access attribute to
9301 an explicit dereference when the context is an access-to-interface
9302 type. In that case we need to apply the conversion to the prefix
9303 of the explicit dereference rather than the prefix of the attribute.
9304 (Attribute_Version, UET_Address): Set entity as internal to ensure
9305 proper dg output of implicit importation.
9306 (Expand_Access_To_Type): Removed.
9307 (Expand_N_Attribute_Reference): Merge the code from the three cases
9308 of access attributes, since the processing is largely identical for
9309 these cases. The substantive fix here is to process the case of a
9310 type name prefix (current instance case) before handling the case
9311 of interface prefixes.

9315 Javier Miranda <miranda@adacore.com>
9316 Robert Dewar <dewar@adacore.com>
9318 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
9319 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
9320 type that is an anonymous access to controlled object, establish
9321 an associated finalization chain to avoid corrupting the global
9322 finalization list when a dynamically allocated object designated
9323 by such a component is deallocated.
9324 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9325 functions that need it, even when not marked Requires_Overriding.
9326 (Initialize_Tag): Replace call to has_discriminants by call to
9327 Is_Variable_Size_Record in the circuitry that handles the
9328 initialization of secondary tags.

9330 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
9331 Suppress_Initialization pragma for a derived type.
9332 (Is_Variable_Size_Record): New subprogram.
9333 (Build_Offset_To_Top_Functions): New implementation that simplifies the
9334 initial version of this routine and also fixes problems causing
9335 incomplete initialization of the table of interfaces.
9336 (Build_Init_Procedure): Improve the generation of code to initialize the
9337 the tag components of secondary dispatch tables.
9338 (Init_Secondary_Tags): New implementation that simplifies the previous
9339 version of this routine.

9343 diagnose attemps to freeze a subprogram when some untagged type of its
9344 profile is a private type whose full view has not been analyzed yet.
9345 (Freeze_Array_Type): Generate init proc for packed array if either
9346 Initialize or Normalize_Scalars is set.
9347 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
9348 constructing the new profile, copy the null_exclusion indicator for each
9349 parameter, to ensure full conformance of the new body with the spec.
9351 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
9352 Create wrappers for constructor functions that need it, even when not
9353 marked Requires_Overriding.

9355 whose non-limited views are themselves incomplete types.
9356 (Add_Entry): Use an entity to store the abstract operation which hides
9358 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

9365 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
9366 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
9367 (Write_Overloads): Output the abstract operator if present.
9368 (Add_Entry): Before inserting a new entry into the interpretation table
9369 for a node, determine whether the entry will be disabled by an abstract
9371 (Binary_Op_Interp_May_Be_Hidden): New routine.
9372 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
9374 (Function_Interp_May_Be_Hidden): New routine.
9375 (Has_Compatible_Type): Do not consider interpretations hidden by
9376 abstract operators when trying to determine whether two types are

9383 Javier Miranda <miranda@adacore.com>
9385 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
9386 types declared in the declarative part of a nested package body or in
9387 the proper body of a stub.

9393 output of implicit importation and exportation.
9394 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
9395 first formal of the thunk is always associated with the controlling
9396 type. In addition perform the following code cleanup: remove formal
9397 Thunk_Alias which is no longer required, cleanup evaluation of the
9398 the controlling type, and update the documentation.
9399 Replace occurrence of Default_Prim_Op_Count by
9400 Max_Predef_Prims. Addition of compile-time check to verify
9401 that the value of Max_Predef_Prims is correct.
9402 (Check_Premature_Freezing): Apply check in Ada95 mode as well.

9406 construction of statically allocated dispatch tables.
9407 (Make_DT): In case of library-level tagged types export the declaration
9408 of the primary tag. Remove generation of tags (now done by Make_Tags).
9409 Additional modifications to handle non-static generation of dispatch
9410 tables. Take care of building tables for asynchronous interface types
9411 (Make_Tags): New subprogram that generates the entities associated with
9412 the primary and secondary tags of Typ and fills the contents of Access_
9413 Disp_Table. In case of library-level tagged types imports the forward
9414 declaration of the primary tag that will be declared later by Make_DT.
9415 (Expand_Interface_Conversion): In case of access types to interfaces
9416 replace an itype declaration by an explicit type declaration to avoid
9417 problems associated with the scope of such itype in transient blocks.
9419 2007-08-14 Robert Dewar <dewar@adacore.com>
9420 Ed Schonberg <schonberg@adacore.com>
9421 Javier Miranda <miranda@adacore.com>
9423 * exp_util.ads, exp_util.adb:
9424 This patch replaces a number of occurrences of explicit tests for N_Null
9425 with calls to Known_Null. This improves tracking of null values, since
9426 Known_Null also catches null constants, and variables currently known to
9427 be null, so we get better tracking.
9428 (Ensure_Defined): create an itype reference only in the scope of the
9430 (Side_Effect_Free): A selected component of an access type that
9431 denotes a component with a rep clause must be treated as not
9432 side-effect free, because if it is part of a linked structure its
9433 value may be affected by a renaming.
9434 (Expand_Subtype_From_Expr): For limited objects initialized with build
9435 in place function calls, do nothing; otherwise we prematurely introduce
9436 an N_Reference node in the expression initializing the object, which
9437 breaks the circuitry that detects and adds the additional arguments to
9438 the called function. Bug found working in the new patch for statically
9439 allocated dispatch tables.
9440 (Is_Library_Level_Tagged_Type): New subprogram.
9441 (Remove_Side_Effects): If the expression of an elementary type is an
9442 operator treat as a function call.
9443 (Make_Literal_Range): If the index type of the array is not integer, use
9444 attributes properly to compute the constraint on the resulting aggregate
9447 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
9448 class-wide type whose base type is an incomplete private type, leave
9449 class-wide type unfrozen so that freeze nodes can be generated
9450 properly at a later point.
9451 (Freeze_Entity, array case): Handle case of pragma Pack and component
9452 size attributre clause for same array.

9512 source dirs are not known.
9513 (Check_Ada_Name): Allow all identifiers that are not reserved words
9515 Major update of the Project Manager and of the project aware tools,
9516 including gprmake, so that the same sources in the GNAT repository
9517 can be used by gprbuild.

10101 operations in Derive_Subprograms.
10102 (Collect_Previous_Instances): new procedure within of
10103 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
10104 unit being loaded, to ensure that the generation of global symbols is

10106 (Is_Tagged_Ancestor): New function testing the ancestor relation that
10107 takes progenitor types into account.
10108 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
10109 traversing over the primitives of the formal and actual types to locate
10110 any abstract subprograms of the actual type that correspond to a
10111 nonabstract subprogram of the formal type's ancestor type(s), and issue
10112 an error if such is found.
10113 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
10114 Instantiate_Package_Body, Instantiate_Subprogram_Body):
10115 Remove bogus guard around calls to Inherit_Context.

10127 controlling formal is not an in_parameter, reject the actual if it is
10128 an access_to_constant type.
10129 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
10130 type, the candidate operations are found in the scope of declaration of
10131 the type, because the type has no primitive subprograms.
10132 (Analyze_Selected_Component): If prefix is class-wide, and root type is
10133 a private extension, only examine visible components before trying to
10134 analyze as a prefixed call.
10135 Change Entity_List to Type_To_Use, for better readability.
10136 (Has_Fixed_Op): Use base type when checking whether the type of an

10145 formal At_Any_Place indicating, when True, that we want to test for
10146 availability of the stream attribute at any place (as opposed to the
10147 current visibility context only).
10148 (Missing_Read_Write_Attributes): A stream attribute is missing for the
10149 purpose of enforcing E.2.2(8) only if it is not available at any place.
10150 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
10151 when checking the legality of an extension aggregate in a preelaborable
10152 package. Treat the literal null as a valid default expression in a

11400 overloading cases, when several ancestors may have class-wide operations
11401 that are possible candidates, and when the overloaded functions return

11406 successive actuals before analyzing the call itself.

11422 aliased when the corresponding controlling formal is an access
11424 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly

11429 whether a function that returns an unconstrained type can be inlined.
11430 (Process_Formals): Diagnose properly the illegal use of an incomplete
11431 type in the profile of an access_to_subprogram declaration.
11432 (Check_Synchronized_Overriding): Nothing check for concurrent types, the

11436 interface change the type of all controlling formals to that of the
11437 corresponding record type.
11438 (Check_Synchronized_Overriding): Relax the conditional logic when trying
11439 to determine the tagged type to which a primitive belongs.
11440 (Check_Conventions): Capture condition to ignore a primitive operation
11441 (which is shared between the loop in Check_Conventions and the one in
11442 Check_Convention) in a new local function Skip_Check.
11443 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
11444 confusion with Check_Conventions' own Prim_Op local variable.
11445 (Create_Extra_Formals): Test for a tagged result type rather than a
11446 controlling result when determining whether to add a BIP_Alloc_Form
11447 formal and a BIP_Final_List formal to the function.
11448 (Check_Conformance); For parameters that are anonymous access types,
11449 subtype conformance requires that the not null and the constant
11450 indicators must match
11451 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
11452 to retrieve the appropriate type when processing a concurrent type
11453 declared within a generic. Minor comment reformatting. Change invocation
11454 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
11456 (Analyze_Subprogram_Body): If the return type of a function is an
11457 anonymous access to the limited view of a class-wide type, and the
11458 non-limited view of the type is available, update the type of the
11459 function so that code can be generated.
11460 (Process_Formals): In case of access-subtype itype whose designated
11461 type is also an itype (situation that happens now with access to
11462 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
11463 attribute to avoid backend problems.
11464 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
11465 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
11466 anonymous types' designated types are same before testing
11467 Subtypes_Statically_Match.
11468 (Create_Extra_Formals): Test for a named access parameter that is a
11469 controlling formal as an additional condition for adding an
11470 accessibility level formal. This can occur in the subp type created for
11471 dispatching calls in Expand_Dispatching_Call, and allows calling
11472 Create_Extra_Formals from that procedure rather than special-casing the
11473 extra formals there.
11474 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
11475 when the function has a controlling result.
11476 (Check_Returns): Add much more knowledge of the optimization of local
11477 raise statements to gotos, to retain proper warnings in this case.
11478 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
11479 nodes when looking for last statement.
11481 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
11482 class-wide types visible through limited with clauses.
11483 (Add_One_Interp): If the operands are anonymous access types, the
11484 predefined operator on universal_access is immediately visibles
11485 (Find_Unique_Type): Handle anonymous access to subprogram types just as
11486 other anonymous access types.
11487 (Disambiguate): Take into account CIL convention.
11488 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
11490 2007-06-06 Robert Dewar <dewar@adacore.com>
11492 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
11493 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
11494 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
11495 Fix lower bound of tables.
11498 * nlists.adb: Ditto.
11499 (Prev_Node, Next_Node): Change index type to Int so that it properly
11500 covers the range First_Node_Id - 1 up.
11502 2007-06-06 Javier Miranda <miranda@adacore.com>
11503 Ed Schonberg <schonberg@adacore.com>
11504 Bob Duff <duff@adacore.com>
11505 Hristian Kirtchev <kirtchev@adacore.com>
11507 * exp_aggr.ads, exp_aggr.adb:
11508 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
11509 in extension aggregates.
11510 (Flatten): Other conditions being met, an aggregate is static if the
11511 low bound given by component associations is different from the low
11512 bound of the base index type.
11513 (Packed_Array_Aggregate_Handled): If the component type is itself a
11514 packed array or record, the front-end must expand into assignments.
11515 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
11516 Init_Pr, instead of Ancestor_Is_Expression.
11517 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
11518 coextension chain root, either generate a list controller or use the
11519 already existing one.
11520 (Static_Array_Aggregate): New procedure to construct a positional
11521 aggregate that can be handled by the backend, when all bounds and
11522 components are compile-time known constants.
11523 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
11524 types covering interface types into assignments.
11525 (Replace_Type): move to Build_Record_Aggr_Code.
11526 (Expand_Record_Aggr_Code): if the target of the aggregate is an
11527 interface type, convert to the definite type of the aggregate itself,
11528 so that needed components are visible.
11529 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
11530 components and the context is an extended return statement do not
11531 create a transient block for it, to prevent premature finalization
11532 before the return is executed.
11533 (Gen_Assign): Do not generate a call to deep adjust routine if the
11534 component type is itself an array of controlled (sub)-components
11535 initialized with an inner aggregate.
11536 (Component_Check): New name for Static_Check. This name is now more
11537 appropriate, and documentation is added which was missing.
11538 (Component_Check): Add test for bit aligned component value
11539 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
11540 Tagged_Comps, name is more appropriate given added function below.
11541 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
11543 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
11544 Javier Miranda <miranda@adacore.com>
11545 Robert Dewar <dewar@adacore.com>
11547 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
11548 Terminated: Add unchecked type conversion from System.Address to
11549 System.Tasking.Task_Id when calling the predefined primitive
11551 Disable new Ada 05 accessibility check for JVM.NET targets, which
11552 cannot be implemented in a practical way.
11553 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
11554 the sources always references the tag of the actual object. Therefore,
11555 if 'Tag is applied in the sources to class-wide interface objects we
11556 generate code that displaces "this" to reference the base of the object.
11557 (Expand_N_Attribute_Reference, case Size): Return specified size if
11558 known to front end.
11559 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
11560 has code that displaces the pointer of the object to manage interface
11561 types. However this code must not be executed when the prefix is a
11562 subprogram. This bug caused the wrong expansion of the internally
11563 generated assignment that fills the dispatch table when the primitive
11564 is a function returning a class-wide interface type.
11565 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
11566 Set_Attribute_Name for Name_Unaligned_Valid.
11568 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11569 Gary Dismukes <dismukes@adacore.com>
11571 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
11572 If the initialization is the equivalent aggregate of the initialization
11573 procedure of the type, do not remove it.
11574 (Expand_N_Attribute_Definition_Clause): Exclude access variables
11575 initialized to null from having their expression reset to empty and
11576 note this exception in the comment.

11579 Robert Dewar <dewar@adacore.com>
11580 Ed Schonberg <schonberg@adacore.com>
11581 Gary Dismukes <dismukes@adacore.com>
11583 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
11584 Add "with" and "use" clauses for Sem_Attr.
11585 (Expand_Current_Value): Do not replace occurences of attribute
11586 references where the prefix must be a simple name.
11588 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
11589 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
11590 Attribute_Requires_Simple_Name_Prefix.
11591 (Name_Modifies_Prefix): Body of new function.
11592 (Requires_Simple_Name_Prefix): Body of new function.
11593 (Resolve_Attribute, case Access): Improve error message for case of
11594 mismatched conventions.
11595 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
11597 (Analyze_Attribute, case 'Access): If the type of the prefix is a
11598 constrained subtype for a nominal unconstrained type, use its base type
11599 to check for conformance with the context.
11600 (Resolve_Attribute): Remove test of the access type being associated
11601 with a return statement from condition for performing accessibility
11602 checks on access attributes, since this case is now captured by
11603 Is_Local_Anonymous_Access.
11604 (Analyze_Access_Attribute): Set Address_Taken on entity
11605 (Analyze_Attribute, case Address): Set Address_Taken on entity
11606 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
11607 validating an access attribute whose prefix is a current instance.
11608 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
11609 applied to dispatching operations, if freezing is required then we set
11610 the attribute Has_Delayed_Freeze in the prefix's entity.
11611 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
11612 current scope if access of local subprogram taken
11613 (Analyze_Access_Attribute): Check legality of self-reference even if the
11614 expression comes from source, as when a single component association in
11615 an aggregate has a box association.
11616 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
11617 the prefix if it is a protected operation and the attribute is
11618 Unrestricted_Access.
11619 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
11620 reference to the base type of the context, to force a constraint check
11621 when the context is an access subtype with an explicit constraint.
11622 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
11623 node is rewritten as an interface conversion. leave unanalyzed after
11624 resolution, to ensure that type checking against the context will take

11628 Javier Miranda <miranda@adacore.com>
11629 Robert Dewar <dewar@adacore.com>
11631 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
11632 wrapper when the full view of the controlling type of an inherited
11633 function that dispatches on result implements interfaces.
11634 (Expand_N_Object_Declaration): In cases where the type of the
11635 declaration is anonymous access, create finalization list for it.
11636 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
11637 if the object has no explicit initialization, to match description of
11638 functionality of pragam Persistent_BSS.
11639 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
11640 new function to build static aggregates, to replace initialization call
11641 when static initialization is desired.
11642 (Freeze_Type): Generate a list controller for an access type whenever
11643 its designated type has controlled anonymous access discriminants.
11644 (Build_Equivalent_Aggregate): New procedure to compute a static
11645 aggregate to be used as default initialization for composite types,
11646 instead of a generating a call to the initialization procedure for the
11648 (Build_Initialization_Call): When available, replace a call to the
11649 initialization procedure with a copy of the equivalent static aggregate
11651 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
11652 declarations for objects of a class-wide interface type, rather than
11653 just identifiers, to prevent visibility problems.
11654 (Expand_N_Object_Declaration): When expanding the declaration for an
11655 object of a class-wide interface type, preserve the homonym chain of
11656 the original entity before exchanging it with that of the generated
11657 renaming declaration.
11658 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
11659 active, because there is no way to handle the exception.
11660 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
11661 to do a minimum decoration of the Access_Disp_Table list.
11662 (Expand_Record_Controller): Avoid the addition of the controller between
11663 the component containing the tag of a secondary dispatch table and its
11664 adjacent component that stores the offset to the base of the object.
11665 This latter component is only generated when the parent type has
11666 discriminants ---documented in Add_Interface_Tag_Components).
11667 (Apply_Array_Size_Check): Removed, no longer needed.
11668 (Expand_N_Full_Type_Declaration): If the type has anonymous access
11669 components, create a Master_Entity for it only if it contains tasks.
11670 (Build_Init_Procedure): Suppress the tag assignment compiling under
11672 (Freeze_Record_Type): Remove code associated with creation of dispatch
11674 (Init_Secondary_Tags): Update type of actuals when generating calls to
11675 Ada.Tags.Set_Offset_To_Top
11676 (Stream_Operation_OK): Disable use of streams compiling under no
11678 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
11679 if Has_Init_Expression set.
11680 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
11681 Register_Primitive, which provides the same functionality.
11682 (Requires_Init_Proc): Return false in case of interface types.
11683 (Add_Secondary_Tables): Use the new attribute Related_Interface to
11685 (Predefined_Primitive_Freeze): Do not assume that an internal entity
11686 is always associated with a predefined primitive because the internal
11687 entities associated with interface types are not predefined primitives.
11688 Therefore, the call to Is_Internal is replaced by a call to the
11689 function Is_Predefined_Dispatching_Operation.
11690 (Make_Eq_If): When generating the list of comparisons for the
11691 components of a given variant, omit the controller component that is
11692 present if the variant has controlled components.
11694 2007-06-06 Javier Miranda <miranda@adacore.com>
11695 Hristian Kirtchev <kirtchev@adacore.com>
11696 Bob Duff <duff@adacore.com>
11698 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
11699 handle the creation of finalization lists and calls for nested
11700 coextensions when the root of the chains is part of a return statement.
11701 (Inside_A_Return_Statement): New function inside Complete_Coextension_
11703 (Expand_Record_Equality): Skip components that are interface types.
11704 (Displace_Allocator_Pointer): Add missing support for interface subtypes
11705 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
11706 with Rewrite_Coextension. Change the condition for detecting coextension
11708 (Is_Local_Access_Discriminant): Removed.
11709 (Rewrite_Coextension): New routine which rewrites a static coextension
11710 as a temporary and uses its unrestricted access in the construction of
11712 (Complete_Coextension_Finalization): New routine. Generate finalization
11713 attachment calls to all delayed coextensions.
11714 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
11715 the allocator is not a coextension itself and has delayed coextensions.
11716 If the current allocator is controlled, but also a coextension, delay
11717 the generation of the finalization attachment call.
11718 Rename local variable "Node" to "Nod" in order to avoid confusion with
11720 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
11721 limited types that are not inherently limited. Such an allocator is
11722 illegal, but is generated by the expander for a return statement, to
11723 copy the result onto the secondary stack. This is the only case where a
11724 limited object can be copied. Generate code to displace the pointer
11725 to the object if the qualified expression is a class-wide interface
11726 object. Such displacement was missing and hence the copy of the object
11728 (Apply_Accessibility_Check): Handle allocated objects initialized in
11730 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
11731 and Expand_Allocator_Expression. Allocating class-wide interface objects
11732 this routine displaces the pointer to the allocated object to reference
11733 the component referencing the corresponding secondary dispatch table.
11734 Expand_Allocator_Expression): Add missing support to allocate class-wide
11735 interface objects initialized with a qualified expression.
11736 (Get_Allocator_Final_List): Test for an anonymous access type that is a
11737 function result type, and use the finalization list associated with the
11738 function scope in that case (such an anonymous type should not be
11739 treated like an access parameter's type).
11741 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11742 Gary Dismukes <dismukes@adacore.com>
11743 Javier Miranda <miranda@adacore.com>
11745 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
11746 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
11747 required exception handler.
11748 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
11749 properly the case of a function whose return type is a limited
11750 class-wide interface type. Modify the code of the accessibility
11751 check to handle class-wide interface objects. In this case we need to
11752 displace "this" to reference the primary dispatch table to get access
11753 to the TSD of the object (to evaluate its accessibility level).
11754 (Expand_N_Extended_Return_Statement): Test for a tagged result type
11755 rather than a controlling result as one of the conditions for
11756 generating tests of the implicit BIP_Alloc_Form formal. The
11757 initialization assignment is also handled according to whether the
11758 result is tagged instead of controlling.
11759 In the case where the init assignment is inserted in the "then" part of
11760 the allocation conditional, rewrite the target to be a dereference of
11761 the implicit BIP_Object_Access formal.
11762 If the returned value is unconstrained and created on the secondary
11763 stack, mark the enclosing block and function so that the secondary
11764 stack is not reclaimed on return.
11765 Treat returns from functions with controlling results similarly to
11766 returns from functions with unconstrained result subtypes.
11767 If the object returned is unconstrained, and an allocator must be
11768 created for it, analyze the allocator once the block for the extended
11769 return is installed, to ensure that finalizable components
11770 of the expression use the proper finalization list. Guard the call to
11771 Move_Final_List with a check that there is something to finalize.
11772 (Make_Tag_Ctrl_Assignment): Use "old" handling
11773 of controlled type assignment for virtual machines, since new code uses
11774 unsupported features (such as direct access to bytes in memory).
11776 2007-06-06 Gary Dismukes <dismukes@adacore.com>
11777 Ed Schonberg <schonberg@adacore.com>
11779 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
11780 accessibility actual, check for the case of an aliased object that has
11781 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
11782 we fall into processing for the attribute rather than the name of the
11784 (Expand_Inline_Call): If an actual is a literal, and the corresponding
11785 formal has its address taken in the body, create a temporary to capture
11786 value. If the return type is a limited interface, do not treat the
11787 return value as Controlled.
11788 (Is_In_Place_Function): If the return type is a limited interface,
11789 treat as returning in place. The actual returned object may not always
11790 be limited, but the caller has to assume that it is returned in place.
11791 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
11792 context of an allocator, use the correct finalization chain (that is,
11793 the chain belonging to the access type, rather than the chain belonging
11794 to the current scope).
11795 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
11796 result type rather than a controlling result as a precondition for
11797 adding an allocation form actual to a build-in-place call.
11798 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
11799 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
11800 primitive in the dispatch tables. This work is now done by Make_DT when
11801 the type is frozen.
11802 (Register_Predefined_DT_Entry): Removed.
11803 (Add_Return): If end label is not present, use sloc of last statement
11804 for generated return statement in procedure, for better gdb behavior
11806 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
11807 object address nodes to ensure proper processing by routines like
11809 (Expand_Call): Fix generation of validity check for parameter
11810 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
11811 the allocation form parameter if the result subtype is constrained,
11812 except when the function has a controlling result.
11813 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
11814 rather than Is_Controlled and Has_Controlled_Component, since we want to
11815 include class-wide result types in this treatment. Also test for a
11816 controlling result, since that also requires passing a finalization
11818 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
11819 even when the result subtype is constrained, to handle calls involving
11820 controlling results.
11821 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
11822 is now called even when the result subtype is constrained, to handle
11823 calls involving controlling results.
11824 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
11825 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
11826 now performs the test).
11827 (Make_Build_In_Place_Call_In_Object_Declaration):
11828 Add_Alloc_Form_Actual_* is now called even when the result subtype is
11829 constrained, to handle calls involving controlling results.
11830 (Add_Return): Accomodate rewritten pattern from local raise to goto
11831 transformation, so that we still recognize an transfer statement
11832 and do the right thing here in that case.
11833 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
11834 and end of subprogram code.
11835 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
11836 support for primitives that are functions (without formals) with a
11837 controlling result.
11838 (Inherited_From_Formal): If the actual subtype has not generic parent
11839 type, it is not an actual for a formal derived type, and there is no
11840 operation to inherit from the formal.
11842 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11843 Thomas Quinot <quinot@adacore.com>
11845 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
11846 inserted cleanup code appropriately for GDB use.
11847 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
11848 exception handler for Deep_Adjust or Deep_Finalize.
11849 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
11850 Raise_From_Controlled_Operation is available, use a call to that
11851 subprogram instead of a plain "raise Program_Error" node to raise
11852 Program_Error if an exception is propagated from an Adjust or Finalize
11854 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
11855 appears in the optional statement list of a triggering alternative, the

11889 Otherwise any serious error
11890 reported by the backend calling the frontend routine Error_Msg

12033 subtype from the function call, as is done for private types.
12034 (Side_Effect_Free): An expression that is the renaming of an object or
12035 whose prefix is the renaming of a object, is not side-effect free
12036 because it may be assigned through the renaming and its value must be

12789 Set_All_DT_Position now ensures that the same slot is now assigned to
12790 both entities. This is required to statically build the dispatch table.
12791 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
12792 of calling Set_All_DT_Position to re-evaluate the position of the
12793 entries in the dispatch table. Such reevaluation is not desired if
12794 the tagged type is already frozen.

13702 object of a null-excluding access type then don't require the
13703 the object declaration to have an expression and don't emit a

13766 (E_Return_Statement): This node type has the Finalization_Chain_Entity
13767 attribute, in case the result type has controlled parts.
13768 (Requires_Overriding): Add this new flag, because "requires
13769 overriding" is subtly different from "is abstract" (see AI-228).
13770 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
13771 Is_Abstract_Type. Make sure these are called only when appropriate.

13833 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
13834 "abstract subprograms must be visible" message, whether or not the type
13835 is an interface; that is, remove the special case for interface types.

13862 Remove no longer used entities.
13864 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

13912 attempt to derive from a synchronized tagged type.
13913 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
13914 type, inherit the class-wide type already created, because it may
13915 already have been used in a self-referential anonymous access component.
13916 (Mentions_T): Recognize self-referential anonymous access components
13917 that use (a subtype of) the class-wide type of the enclosing type.
13918 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
13919 Derived_Type for Prev formal on call to
13920 Check_Anonymous_Access_Components rather than Empty.
13921 (Make_Incomplete_Type_Declaration): Add test for case where the type has
13922 a record extension in deciding whether to create a class-wide type,

13939 with abstract interfaces.
13940 (Analyze_Subtype_Indication): Resolve the range with the given subtype

13968 (Compile_Sources): Do nothing, not even check if the source is up to
13969 date, if its project is externally built.
13970 (Compile): When compiling a predefined source, add -gnatpg
13971 as the second switch, after -c.

13976 gnatbind if the ALI file effectively exists.
13977 (Initialize): Add the directory where gnatmake is invoked in front of
13978 the path if it is invoked from a bin directory, even without directory

14003 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
14004 when -gnatg is not specified.
14005 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
14006 there is no need to generate always a record_definition_node in case
14007 of synchronized interface types.

14034 (Convert_Aggr_In_Allocator): If the allocator is for an access
14035 discriminant and the type is controlled. do not place on a finalization
14036 list at this point. The proper list will be determined from the

14055 succeed in that case, even when the expression originates from a
14056 parameter of the containing subprogram.
14057 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
14058 under No_Dispatching_Calls restriction. During the semantic analysis
14059 we already notified such violation.

14077 initialize most the TSD components by means of an aggregate.
14078 Modify the declaration of the object containing the TSD
14079 because we now expand code that has a higher level of abstraction.
14080 The TSD has a discriminant containing the Inheritance Depth Level,
14081 value that is used in the membership test but also to fix the size
14082 of the table of ancestors.
14083 (Expand_Interface_Conversion): Insert function body at the closest place
14084 to the conversion expression, to prevent access-before-elaboration

14111 (Expand_Dispatching_Call): Replace generation of call to the run-time
14112 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
14113 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
14115 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
14116 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

14118 Build_Set_Prim_Op_Address.
14119 (Get_Remotely_Callable): Subprogram removed.
14120 (Init_Predefined_Interface_Primitives): Replace generation of call to
14121 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
14124 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to

14126 returns an actual parameter expression for both named and positional
14129 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
14130 check violation of restriction No_Dispatching_Calls.
14131 (Check_Controlling_Type): A formal of a tagged incomplete type is a
14132 controlling argument.

14135 First/Next_Component_Or_Discriminant
14136 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
14137 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14138 specify Any_Limited_Interface, and this functionality is already
14139 provided by the function Has_Abstract_Interfaces.
14140 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
14141 support concurrent types implementing interfaces.
14142 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14143 specify kind Any_Limited_Interface, and this functionality is already

14160 Cyrille Comar <comar@adacore.com>
14162 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
14163 anonymous, use finalization list of enclosing dynamic scope.
14164 (Expand_N_Package_Declaration): For a library package declaration
14165 without a corresponding body, generate RACW subprogram bodies in the
14166 spec (just as we do for the task activation call).
14167 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
14168 Is_Abstract_Type. Make sure these are called only when appropriate.
14169 Remove all code for DSP option
14170 (CW_Or_Controlled_Type): new subprogram.
14172 2007-04-06 Eric Botcazou <botcazou@adacore.com>

14174 Gary Dismukes <dismukes@adacore.com>
14176 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
14177 parameter. If it is set to true, return a result capped according to
14178 the global upper bound for the index of an entry family.
14179 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
14180 (Build_Find_Body_Index): Adjust for above change.
14181 (Entry_Index_Expression): Likewise.
14182 (Is_Potentially_Large_Family): New function extracted from...
14183 (Collect_Entry_Families): ...here. Call it to detect whether the family
14184 is potentially large.
14185 (Build_Entry_Count_Expression): If the family is potentially large, call
14186 Family_Size with 'Cap' set to true.
14187 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
14188 a protected version of an operation declared in the private part of
14189 a protected object, because they may be invoked through a callback.
14190 (Set_Privals): If the type of a private component is an anonymous access
14191 type, do not create a new itype for each protected body.
14192 If the body of a protected operation creates
14193 controlled types (including allocators for class-widetypes), the
14194 body of the corresponding protected subprogram must include a
14196 (Build_Activation_Chain_Entity): Build the chain entity for extended
14198 (Type_Conformant_Parameters): Use common predicate Conforming_Types
14199 to determine whether operation overrides an inherited primitive.
14200 (Build_Wrapper_Spec): Add code to examine the parents while looking
14201 for a possible overriding candidate.
14202 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
14203 hold an actual parameter value since its initialization is separated
14204 from the the declaration. Prevents errors on null-excluding access
14207 2007-04-06 Thomas Quinot <quinot@adacore.com>
14208 Pablo Oliveira <oliveira@adacore.com>
14210 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
14211 Do an Unchecked_Conversion to handle the passage from the Underlying
14212 Type to the Base Type when calling Build_To_Any_Call and
14213 Build_From_Any_Call.
14214 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
14215 E_Constant, depending upon Variable formal.
14216 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14217 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
14218 parameter that requires an extra constrained parameter, declare
14219 temporary for actual as a variable, not a constant.
14220 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
14221 the unit being compiled is the one that contains the stub type.
14222 Change primitive operation name for the RACW associated with a RAS
14223 from Call to _Call so it cannot clash with any legal identifier.
14224 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
14226 (Append_RACW_Bodies): New subprogram.
14227 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
14228 Add_Receiving_Stubs_To_Declarations functions.
14229 When expanding a package body, this list correspond to the
14230 statements in the HSS at the end of the pacakge.
14231 When expanding a package spec, this list correspond to the
14233 (Add_Receiving_Stubs_To_Declarations): Append the function
14234 registering the receiving stubs at the end of the 'Stmts' list.
14235 (RCI_Package_Locator): Pass the new Version generic formal when
14236 instantiating a RCI_Locator package.
14237 (Build_From_Any_Function): To compute the High bound for an
14238 unconstrained array actual, we add the Low bound with the length.
14239 Thus we must convert the low bound and the length to an appropriate
14240 type before doing the sum.
14241 (Build_Subprogram_Receiving_Stubs, PolyORB):
14242 * Retrieve the extra formals parameters at the
14243 end of the parameter stream.
14244 * Use Move_Any_Value to write back out parameters
14245 after executing the request as it is more efficient
14246 than Copy_Any_Value.
14247 * Build the any containing Extra Formals with the
14248 appropriate typecode.
14249 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
14250 empty Component_List.
14251 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
14252 the tree the declaration for an object that serves as actual parameter
14253 in server-side stubs.
14254 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14255 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14256 Use Build_Actual_Object_Declaration to prepare the actuals.

14258 Extra Constrained Parameters.
14259 (Build_General_Calling_Stubs): Set the parameter type to boolean for
14260 Extra Constrained parameters.

14263 function with the first not implicit parent type.
14264 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
14265 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
14266 typecode from the Etype. Therefore we retrieve the correct typecode
14267 with a call to Get_Any_Type.
14268 (Copy_Specification): Do controlling formal type substitution based on
14269 Is_Controlling_Formal flag, instead of caller-provided object type.
14270 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
14271 a RACW primitive operation, we might get a subprogram declaration for an
14272 ancestor of the RACW designated type (not for the designated type
14273 itself), in the case where this operation is inherited. In this case we
14274 have no easy means of determining the original tagged type for which
14275 the primitive was declared, so instead we now rely on
14276 Copy_Specification to use the Is_Controlling_Formal flag to determine
14277 which formals require type substitution.

14283 GNAT.Current_Exception are not allowed if pragma Restrictions
14284 (No_Exception_Propagation) is set and in any case make the associated
14285 handler unsuitable as a target for a local raise statement.
14286 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
14287 run-time subprogram CW_Membership by call to Build_CW_Membership.
14288 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
14289 by a function call, a temporary must be created before expanding the
14290 Constructor_Call itself, to prevent out-of-order elaboration in the
14291 back-end when stack checking is enabled..
14293 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14295 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
14296 result are the bounds of the left operand, not the right.
14298 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14301 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

14313 box corresponds to a component of the type.
14314 (Resolve_Record_Aggregate): Split Is_Abstract flag into
14315 Is_Abstract_Subprogram and Is_Abstract_Type.

14418 * mingw32.h (S2WSU): New macro to convert from a string to a
14419 wide-string using the UTF-8 encoding. The S2WS macro supports now only
14420 standard 8bits encoding.
14421 (WS2SU): As above but converting from wide-sring to string.
14422 This is needed as it is necessary to have access to both versions in the
14423 runtime for the form parameter encoding support.
14424 This set of patch add support for the encoding form parameter.
14425 (S2WS): Improve implementation to handle cases where the filename is not
14426 UTF-8 encoded. In this case we default to using the current code page
14427 for the conversion.

14474 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
14475 __gnat_adjust_context_for_raise.
14476 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
14477 implementation of floating point operations as native x86 targets.
14478 So the FPU should be initialized in the same way using finit. Fix
14479 floating point operations accuracy issues.
14480 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
14481 member in struct sigaction, so as to avoid warning for incompatible

14500 Modify the loop that collects type references, to include interface
14501 types that the type implements. List each of these interfaces when
14502 building the entry for the type.
14503 (Generate_Definition): Initialize component Def and Typ of new entry
14504 in table Xrefs, to avoid to have these components unitialized.

14550 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
14551 it no longer destroys the contents of Name_Buffer or Name_Len and
14552 non-standard and invalid names are handled better.

14562 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
14563 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
14564 there is no need to generate always a record_definition_node in case
14565 of synchronized interface types.
14566 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
14567 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
14568 illegal in Ada 95, in cases where it is legal. Change the warnings to
14569 errors in other cases. Don't give the error unless the "not null"
14570 parses properly. Correct the source position at which the error occurs.
14571 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
14572 P_Null_Exclusion, to suppress "not null" warnings.

14624 Entry for pragma Unreferenced_Objects
14626 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
14627 switches, without repetition of "eD". Make sure that last character of
14628 -gnatep= switch is not taken as -gnat switch character.
14629 Complete rewrite of circuit for handling saving compilation options

14648 the default project path, initially done during elaboration of the
14650 If the prefix returned by Sdefault is null, get the prefix from a call
14651 to Executable_Prefix_Path.
14652 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
14655 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
14656 canonical directory name to open the directory from which files are
14658 (Record_Other_Sources): Idem.
14659 (Locate_Directory): Add the possibility to create automatically missing
14660 directories when Setup_Projects is True.
14661 Call Locate_Directory so that the directory will be created when

14663 library source copy dir and exec dir.
14665 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
14668 2007-04-06 Robert Dewar <dewar@adacore.com>

14683 Next_Component_Or_Discriminant.
14685 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
14688 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch

14703 full word is no longer compared twice.
14705 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14707 * sem_ch10.adb (Install_Limited_Context_Clauses.
14708 Expand_Limited_With_Clause): Use a new copy of selector name in the
14709 call to Make_With_Clause. This fixes the tree structure for ASIS
14710 purposes. Nothing is changed in the compiler behaviour.
14711 (Process_Body_Clauses): Handle properly use clauses whose prefix is
14712 a package renaming.
14713 (Install_Limited_With_Clauses): Do not install non-limited view when it
14714 is still incomplete.
14716 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14717 Gary Dismukes <dismukes@adacore.com>
14719 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
14720 when capturing size information, instead of base type, which for a
14721 formal array type will be the unconstrained type.
14722 (Analyze_Formal_Object_Declaration): Add check for illegal default
14723 expressions for a formal in object of a limited type.
14724 (Instantiate_Object): Ditto.
14725 (Check_Formal_Package_Instance): Skip entities that are formal objects,
14726 because they were defaulted in the formal package and no check applies
14728 (Check_Formal_Package_Instance): Extend conformance check to other
14729 discrete types beyond Integer.
14730 (Process_Default): Copy directly the unmatched formal. A generic copy
14731 has already been performed in Analyze_Formal_Package.
14732 (Analyze_Associations): If a formal subprogram has no match, check for
14733 partial parametrization before looking for a default, to prevent
14735 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
14736 not set the instantiation environment before analyzing the actuals.
14737 Fixes regression on 8515-003 with implementation of AI-133.
14738 Set_Instance_Env checks whether the generic unit is a predefined
14739 unit, in which case the instance must be analyzed with the latest Ada
14740 mode. This setting must take place after analysis of the actuals,
14741 because the actuals must be analyzed and frozen in the Ada mode extant
14742 outside of the current instantiation.
14743 (Save_Env, Restore_Env): Preserve and restore the configuration
14744 parameters so that predefined units can be compiled in the proper Ada
14746 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
14747 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
14748 and Is_Abstract_Type.
14749 (Analyze_Formal_Package): For better error recovery, Add exception
14750 handler to catch Instantion_Error, which can be raised in
14751 Analyze_Associations
14753 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14754 Bob Duff <duff@adacore.com>
14755 Gary Dismukes <dismukes@adacore.com>
14757 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
14758 prefix type is a discriminated subtype of the type of the formal.
14759 (Analyze_Allocator): Collect all coextensions regardless of the context.
14760 Whether they can be allocated statically is determined in exp_ch4.
14761 (Analyze_Selected_Component): If the prefix is a limited view and the
14762 non-limited view is available, use the non-limited one.
14763 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
14764 therefore illegal), suggest a qualified expression rather than a type
14765 conversion, because a type conversion would be illegal in this context.
14766 (Anayze_Allocator): Trace recursively all nested allocators so that all
14767 coextensions are on the corresponding list for the root. Do no mark
14768 coextensions if the root allocator is within a declaration for a stack-
14769 allocated object, because the access discriminants will be allocated on
14771 (Analyze_Call): Remove restriction on calls to limited functions for the
14772 cases of generic actuals for formal objects, defaults for formal objects
14773 and defaults for record components.
14774 (Analyze_Allocator): Before analysis, chain coextensions on the proper
14775 element list. Their expansion is delayed until the enclosing allocator
14776 is processed and its finalization list constructed.
14777 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
14778 for an operation with the given name among the primitive operations of
14779 the corresponding record type.
14780 (Analyze_Selected_Component): If the prefix is a task type that
14781 implements an interface, and there is no entry with the given name,
14782 check whether there is another primitive operation (e.g. a function)
14784 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
14785 properly the indexing of a function call written in prefix form, where
14786 the function returns an array type, and all parameters of the function
14787 except the first have defaults.
14788 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
14789 the original operands, rather than relocating them, for efficiency and
14790 to work properly when an operand is overloaded.
14791 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
14792 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
14793 (Analyze_Selected_Component): If the prefix is a private extension, only
14794 scan the visible components, not those of the full view.
14795 (Try_Primitive_Operation): If the operation is a procedure, collect all
14796 possible interpretations, as for a function, because in the presence of
14797 classwide parameters several primitive operations of the type can match
14798 the given arguments.
14800 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14801 Robert Dewar <dewar@adacore.com>
14803 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
14804 tag-indeterminate call to an abstract function, when the left-hand side
14806 (Analyze_Loop_Statement): Improve detection of infinite loops
14808 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14809 Thomas Quinot <quinot@adacore.com>
14811 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
14812 out of Analyze_Package_Declaration, because processing must be applied
14813 to package bodies as well, for deferred constants completed by pragmas.
14814 (Analyze_Package_Declaration): When the package declaration being
14815 analyzed does not require an explicit body, call Check_Completion.
14816 (May_Need_Implicit_Body): An implicit body is required when a package
14817 spec contains the declaration of a remote access-to-classwide type.
14818 (Analyze_Package_Body): If the package contains RACWs, append the
14819 pending subprogram bodies generated by exp_dist at the end of the body.
14820 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
14821 Is_Abstract_Subprogram and Is_Abstract_Type.
14822 (Preserve_Full_Attributes): The full entity list is not an attribute
14823 that must be preserved from full to partial view.
14825 * sem_dist.adb (Add_RAS_Dereference_TSS):
14826 Change primitive name to _Call so it cannot clash with any legal
14827 identifier, and be special-cased in Check_Completion.
14828 Mark the full view of the designated type for the RACW associated with
14829 a RAS as Comes_From_Source to get proper view switching when installing
14830 private declarations.
14831 Provite a placeholder nested package body along with the nested spec
14832 to have a place for Append_RACW_Bodies to generate the calling stubs
14833 and stream attributes.
14835 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14836 Robert Dewar <dewar@adacore.com>
14838 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
14839 that is a limited view, check the non-limited view if available.
14840 (Undefined): Refine error message for missing with of Text_IO
14841 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
14842 to distinguish real missing with cases.
14843 Fix format of all missing with messages
14844 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
14845 renaming as body when renamed entity is abstract.
14847 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14848 Javier Miranda <miranda@adacore.com>
14850 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
14851 predicate recursive, to handle complex expressions on literals whose
14852 spurious ambiguity comes from the abstract interpretation of some
14854 (Interface_Present_In_Ancestor): Add support to concurrent record
14856 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
14857 Is_Abstract_Subprogram and Is_Abstract_Type.
14859 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14860 Javier Miranda <miranda@adacore.com>
14862 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
14863 dereference of a local object R created as a reference to another
14864 object O, use the access level of O.
14865 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
14866 rather than local Same_Formal_Type, to check whether protected operation
14867 overrides an inherited one.
14868 (Same_Formal_Type): New predicate, used when matching signatures of
14869 overriding synchronized operations, to handle the case when a formal
14870 has a type that is a generic actual.
14871 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
14872 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
14873 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
14874 syntactic ambiguities involving indexing of function calls that return
14876 (Abstract_Interface_List): New subprogram that returns the list of
14877 abstract interfaces associated with a concurrent type or a
14878 concurrent record type.
14879 (Interface_Present_In_Parent): New subprogram used to check if a
14880 given type or some of its parents implement a given interface.
14881 (Collect_Abstract_Interfaces): Add support for concurrent types
14882 with interface types.
14883 (Has_Abstract_Interfaces): Add support for concurrent types with
14885 (Is_Parent): New subprogram that determines whether E1 is a parent
14886 of E2. For a concurrent type its parent is the first element of its
14887 list of interface types; for other types this function provides the
14888 same result than Is_Ancestor.
14889 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
14890 (Collect_Synchronized_Interfaces): Removed because the subprogram
14891 Collect_Abstract_Interfaces provides this functionality.
14892 (Collect_Abstract_Interfaces): Minor update to give support to
14893 concurrent types and thus avoid undesired code duplication.
14894 (Get_Subprogram_Entity): Handle entry calls.
14895 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
14897 (Enter_Name): Do not give -gnatwh hiding warning for record component
14898 entities, they never result in hiding.

14911 correspond to access discriminants of dynamically allocated objects.
14912 (N_Block_Statement): Document the fact that the corresponding entity
14913 can be an E_Return_Statement.
14914 (Is_Coextension): New flag for allocators.

14923 before propagating exception.
14925 2007-04-06 Olivier Hainque <hainque@adacore.com>
14927 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
14928 an address always within the call instruction from a return address.
14930 2007-04-06 Olivier Hainque <hainque@adacore.com>
14931 Eric Botcazou <botcazou@adacore.com>
14933 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
14934 expression with a COMPOUND_EXPR including the call instead of emitting
14935 the call directly here.
14936 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
14937 high bound is constant and the slice is empty. Tidy.
14938 (tree_transform, case N_Op_Not): Handle properly the case where the
14939 operation applies to a private type whose full view is a modular type.
14940 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
14941 Address_Clause, use the associated Expression as the GNAT tree
14942 representing the choice value to ensure the corresponding GCC tree is
14943 of the proper kind.
14944 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
14945 instead of just the operands, as the base GCC stabilize_reference does.
14946 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
14947 requested; otherwise fail.
14948 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
14950 2007-04-06 Thomas Quinot <quinot@adacore.com>

14953 implementation of UI_Div.
14954 (UI_Div): Reimplement as a call to UI_Div_Rem.
14955 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
14956 remainder, avoiding the cost of a multiplication and a subtraction.
14957 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
14958 provides both quotient and remainder in a single computation.
14959 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
14960 functions for uint.
14961 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
14962 is undefined if the given n is not inversible.
14964 2007-04-06 Olivier Hainque <hainque@adacore.com>
14966 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
14967 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion
14970 2007-04-06 Eric Botcazou <botcazou@adacore.com>
14971 Olivier Hainque <hainque@adacore.com>
14973 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
14974 when updating the contents of the old pointer to an unconstrained array.
14975 (end_subprog_body): Set error_gnat_node to Empty.
14976 (write_record_type_debug_info): Do not be unduly sparing with our bytes.
14977 (unchecked_convert): For subtype to base type conversions, require that

14982 (gnat_install_builtins): Adjust comments.
14983 (builtin_function): Set DECL_BUILTIN_CLASS and DECL_FUNCTION_CODE before

14985 function declaration node.
14986 (builtin_decl_for): Search the builtin_decls list.
14988 2007-04-06 Eric Botcazou <botcazou@adacore.com>

15227 Valid_Conversion, to incorporate accessibility checks for arrays of
15228 anonymous access types.
15229 (Valid_Conversion): For a conversion to a numeric type occurring in an
15230 instance or inlined body, no need to check that the operand type is
15231 numeric, since this has been checked during analysis of the template.

15901 (Concat): Removed, replaced by real concatenation
15902 Make use of concatenation now allowed in compiler
15903 (Executable_Prefix.Get_Install_Dir): First get the full path, so that
15904 we find the 'lib' or 'bin' directory even when the tool has been
15905 invoked with a relative path.
15906 (Executable_Name): New function taking string parameters.
15908 * osint-c.ads, osint-c.adb:
15909 Implement new -gnatl=xxx switch to output listing to file
15911 * sinput-d.adb: Change name Creat_Debug_File to Create_Debug_File
15914 Implement new -gnatl=xxx switch to output listing to file
15915 Recognize new -gnatL switch
15916 (no longer keep in old warning about old style usage)
15917 Use concatenation to simplify code
15918 Recognize -gnatjnn switch
15919 (Scan_Front_End_Switches): Clean up handling of -gnatW

15935 * exp_aggr.adb (Build_Record_Aggr_Code): For extension aggregates, if
15936 the parent part is a build-in-place function call, generate assignments.
15937 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
15938 are build-in-place function calls.
15939 (Replace_Self_Reference): New subsidiary of
15940 Make_OK_Assignment_Statement, to replace an access attribute that is a
15941 self-reference into an access to the appropriate component of the
15942 target object. Generalizes previous mechanism to handle self-references
15943 nested at any level.
15944 (Is_Self_Referential_Init): Remove, not needed.
15945 (Is_Self_Referential_Init): New predicate to simplify handling of self
15946 referential components in record aggregates.
15947 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
15948 check for presence of entity before checking for self-reference.
15949 (Has_Default_Init_Comps): Return True if a component association is a
15950 self-reference to the enclosing type, which can only come from a
15951 default initialization.
15952 (Make_OK_Assignment_Statement): If the expression is of the form
15953 Typ'Acc, where Acc is an access attribute, the expression comes from a
15954 default initialized self-referential component.
15955 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
15956 that has been derived from several abstract interfaces we must also
15957 initialize the tags of the secondary dispatch tables.
15959 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15960 Thomas Quinot <quinot@adacore.com>
15961 Javier Miranda <miranda@adacore.com>
15962 Robert Dewar <dewar@adacore.com>
15965 (Expand_Access_To_Protected_Op): If the context indicates that an access
15966 to a local operation may be transfered outside of the object, create an
15967 access to the wrapper operation that must be used in an external call.
15968 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
15969 target, pass the Valid attribute applied to a floating-point prefix on
15970 to the back end without expansion.
15971 (Storage_Size): Use the new run-time function Storage_Size to retrieve
15972 the allocated storage when it is specified by a per-object expression.
15973 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
15974 Nothing to do here, the attribute has been rewritten during semantic
15976 (Expand_Attribute_Reference): Handle expansion of the new Priority
15978 (Find_Fat_Info): Handle case of universal real
15979 (Expand_Access_To_Protected_Op): Fix use of access to protected
15980 subprogram from inside the body of a protected entry.
15981 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
15982 'Access and 'Unrestricted_Access, to transform the attribute reference
15983 into a fat pointer.
15984 (Is_Constrained_Aliased_View): New predicate to help determine whether a
15985 subcomponent's enclosing variable is aliased with a constrained subtype.
15986 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
15987 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
15988 an aliased prefix must be known to be constrained in order to use True
15989 for the attribute value, and now it's possible for some aliased views
15990 to be unconstrained.
15992 2006-10-31 Robert Dewar <dewar@adacore.com>
15994 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
15995 (Expand_Entity_Reference): Correct error of not handling subprogram
15996 formals in current_value processing.
15998 2006-10-31 Javier Miranda <miranda@adacore.com>
15999 Robert Dewar <dewar@adacore.com>
16000 Ed Schonberg <schonberg@adacore.com>
16001 Gary Dismukes <dismukes@adacore.com>
16003 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
16004 register in the final list objects containing class-wide interfaces;
16005 otherwise we incorrectly register the tag of the interface in the final
16007 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
16008 generate the wrapper if the parent primitive is abstract. This is
16009 required to report the correct error message.
16010 (Expand_N_Subtype_Indication): Do validity checks on range
16011 (Clean_Task_Names): If an initialization procedure includes a call to
16012 initialize a task (sub)component, indicate that the procedure will use
16013 the secondary stack.
16014 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
16015 compatibility for interfacing with CPP by default.
16016 (Expand_N_Object_Declaration): Only build an Adjust call when the
16017 object's type is a nonlimited controlled type.
16018 * exp_ch3.adb: Add with and use of Exp_Ch6.
16019 (Expand_N_Object_Declaration): Check for object initialization that is a
16020 call to build-in-place function and apply Make_Build_In_Place_Call_In_
16021 Object_Declaration to the call.
16022 (Freeze_Type): When the designated type of an RACW was not frozen at the
16023 point where the RACW was declared, validate the primitive operations
16024 with respect to E.2.2(14) when it finally is frozen.
16025 (Build_Initialization_Call,Expand_Record_Controller): Rename
16026 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
16027 return-by-reference has no meaning in Ada 2005.
16028 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
16029 to register tag of the immediate ancestor interfaces in the
16030 run-time structure.
16031 (Init_Secondary_Tags): Moved to the specification to allow the
16032 initialization of extension aggregates with abstract interfaces.
16033 (Build_Master_Renaming): Make public, for use by function declarations
16034 whose return type is an anonymous access type.
16035 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
16036 Insert_List_Before_And_Analyze after the generation of the specs
16037 associated with null procedures.
16038 (Expand_Tagged_Root): Update documentation in its specification.
16039 (Init_Secondary_Tags): Update documentation.
16040 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
16041 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
16042 then generate code to inherit the contents of the dispatch table
16043 directly from the ancestor.
16044 (Expand_Record_Controller): Insert controller component after tags of
16045 implemented interfaces.
16046 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
16047 create null procedure overridings when null procedures are inherited
16049 (Make_Null_Procedure_Specs): New procedure to generate null procedure
16050 declarations for overriding null primitives inherited from interfaces.
16051 (Is_Null_Interface_Procedure): New function in
16052 Make_Null_Procedure_Specs.
16053 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
16054 immediate ancestor of a tagged type is an abstract interface type we
16055 must generate the specification of the predefined primitives associated
16056 with controlled types (because the dispatch table of the ancestor is
16057 null and hence these entries cannot be inherited). This is required to
16058 elaborate well the dispatch table.

16066 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
16068 (Expand_N_In): Do validity checks on range
16069 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
16070 (Expand_N_Allocator): For "new T", if the object is constrained by
16071 discriminant defaults, allocate the right amount of memory, rather than
16072 the maximum for type T.
16073 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
16074 when the allocator is initialized by a build-in-place call, since the
16075 allocator is already rewritten as a reference to the function result,
16076 and this prevents an unwanted duplication of the function call.
16077 Add with and use of Exp_Ch6.
16078 (Expand_Allocator_Expresssion): Check for an allocator whose expression
16079 is a call to build-in-place function and apply
16080 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
16081 untagged designated types).
16082 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
16083 optimization if source or target is biased.
16084 (Expand_N_Allocator): Add comments for case of an allocator within a
16085 function that returns an anonymous access type designating tasks.
16086 (Expand_N_Allocator): apply discriminant checks for access
16087 discriminants of anonymous access types (AI-402, AI-416)

16092 Ed Schonberg <schonberg@adacore.com>
16094 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
16096 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
16097 (Expand_N_Assignment_Statement): Call
16098 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
16099 build-in-place function call. Currently, this can happen only for
16100 assignments that come from aggregates.
16101 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16102 in order to alleviate the upward compatibility introduced by AI-318.
16103 (Expand_N_Extended_Return_Statement): Add support for handling the
16104 return object as a build-in-place result.
16105 (Expand_Non_Function_Return): Implement simple return statements nested
16106 within an extended return.
16107 (Enable_New_Return_Processing): Turn on the new processing of return
16109 (Expand_Non_Function_Return): For a return within an extended return,
16110 don't raise Program_Error, because Sem_Ch6 now gives a warning.
16111 (Expand_N_Extended_Return_Statement): Implement AI-318
16112 (Expand_Simple_Function_Return): Ditto.
16113 (Expand_N_If_Statement): Handle new -gnatwt warning
16114 (Expand_N_Case_Statement): Handle new -gnatwt warning
16115 (Expand_N_Assignment): Handle assignment to the Priority attribute of
16116 a protected object.
16117 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
16118 validity checking of assignments to elementary record components.
16119 (Expand_N_Return_Statement): return Class Wide types on the secondary
16120 stack independantly of their controlled status since with HIE runtimes,
16121 class wide types are not potentially controlled anymore.
16123 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
16126 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
16127 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
16128 it expects a block, procedure, or task. The return statement will get
16129 turned into a block, and Expand_Cleanup_Actions will happen then.
16131 2006-10-31 Robert Dewar <dewar@adacore.com>
16132 Ed Schonberg <schonberg@adacore.com>
16133 Bob Duff <duff@adacore.com>
16134 Gary Dismukes <dismukes@adacore.com>
16136 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
16138 (Expand_Inlined_Call): Tagged types are by-reference types, and
16139 therefore should be replaced by a renaming declaration in the expanded
16140 body, as is done for limited types.
16141 (Expand_Call): If this is a call to a function with dispatching access
16142 result, propagate tag from context.
16143 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
16145 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
16146 build-in-place when the right-hand side of an assignment is a
16147 build-in-place function call.
16148 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
16149 of the explicit dereference of the allocator to the result subtype of
16150 the build-in-place function. This is needed to satisfy type checking
16151 in cases where the caller's return object is created by an allocator for
16152 a class-wide access type and the type named in the allocator is a
16154 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
16155 conversion of the reference to the declared object to the result subtype
16156 of the build-in-place function. This is needed to satisfy type checking
16157 in cases where the declared object has a class-wide type. Also, in the
16158 class-wide case, change the type of the object entity to the specific
16159 result subtype of the function, to avoid passing a class-wide object
16160 without explicit initialization to the back end.
16161 (Register_Interface_DT_Entry): Moved outside the body of
16162 Freeze_Subprogram because this routine is now public; it is called from
16163 Check_Dispatching_Overriding to handle late overriding of abstract
16164 interface primitives.
16165 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
16166 adding an implicit access actual on a call to a build-in-place function.
16167 (Expand_Actuals): Test for an actual parameter that is a call to a
16168 build-in-place function and apply
16169 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
16170 (Is_Build_In_Place_Function): New function to determine whether an
16171 entity is a function whose calls should be handled as build-in-place.
16172 (Is_Build_In_Place_Function_Call): New function to determine whether an
16173 expression is a function call that should handled as build-in-place.
16174 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
16175 calls to build-in-place functions as the initialization of an allocator.
16176 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
16177 handling calls to build-in-place functions in contexts that do not
16178 involve init of a separate object (for example, actuals of subprogram
16180 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
16181 handling calls to build-in-place functions as the initialization of an
16182 object declaration.
16183 (Detect_Infinite_Recursion): Add explicit parameter Process to
16184 instantiation of Traverse_Body to avoid unreferenced warning.
16185 (Check_Overriding_Inherited_Interfaces): Removed.
16186 (Register_Interface_DT_Entry): Code cleanup.
16187 (Register_Predefined_DT_Entry): Code cleanup.
16188 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
16189 inlined statements if within a transient scope.
16190 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
16191 formal parameters with occurrences of actuals in inlined body, establish
16192 visibility on the proper view of the actual's subtype for the body's
16194 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
16195 compatibility mode and we have an imported CPP subprogram because
16196 for now we assume that imported CPP primitives correspond with
16197 objects whose constructor is in the CPP side (and therefore we
16198 don't need to generate code to register them in the dispatch table).
16199 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
16200 aligned selected component.
16201 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
16202 the actual of an in-mode parameter is a type conversion.
16203 (Expand_Actuals): If the call does not come from source and the actual
16204 is potentially misaligned, let gigi handle it rather than rejecting the
16205 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
16206 Class Wide types as returning by reference independantly of their
16207 controlled status since with HIE runtimes class wide types are not
16208 potentially controlled anymore.
16210 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16212 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
16213 references that are private components of the protected object.
16214 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
16215 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
16216 instantiation to deal with warnings.
16217 (Initialize_Protection): If expression for priority is non-static, use
16218 System_Priority as its expected type, in case the expression has not
16221 2006-10-31 Robert Dewar <dewar@adacore.com>
16223 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
16224 initialization of Homonym_Len.
16225 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
16226 names from fully qualified name. Fixes problem of duplicate
16227 external names differing only in the presence of such a block name.
16229 2006-10-31 Thomas Quinot <quinot@adacore.com>
16230 Pablo Oliveira <oliveira@adacore.com>
16232 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
16233 subprogram Ids, even if they are not yet assigned.
16234 (Build_Subprogram_Id): It is now this function that will take care of
16235 calling Assign_Subprogram_Ids if necessary.
16236 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
16237 should be done only once they are assigned.
16238 (Build_From_Any_Function, case of tagged types): Add missing call to
16240 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
16241 type for an RACW type.
16242 (Add_RACW_Features): When processing an RACW declaration for which the
16243 designated type is already frozen, enforce E.2.2(14) rules immediately.
16244 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
16245 special reordering of controlling formals.
16247 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
16248 associated stub type for an RACW type.
16250 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16252 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
16253 fixed-point operations in an integer context, i.e. as operands of a
16254 conversion to an integer type, indicate that result must be rounded.
16256 2006-10-31 Robert Dewar <dewar@adacore.com>
16258 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
16259 cases, pass the encoding method, since it is now required by the run
16262 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
16263 assumption that Str'First = 1.
16264 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
16265 it on to the Value_Wide_Wide_Character call.
16266 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
16267 properly handles a string of the form quote-encoded_wide_char-quote.
16269 * s-wchcnv.adb: Minor reformatting
16271 2006-10-31 Javier Miranda <miranda@adacore.com>
16273 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
16274 run-time membership test to ensure that the constructed object
16275 implements the target abstract interface.
16277 2006-10-31 Robert Dewar <dewar@adacore.com>
16279 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
16280 Machine_Attribute pragma internally to implement the user pragma.
16281 Add processing for pragma Interface so that it is now completely
16282 equivalent to pragma Import.
16284 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
16285 so that it can be applied to all entities, including record components
16286 and enumeration literals.
16287 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
16288 priority ranges are correct, verify compatibility against task
16289 dispatching and locking policies, and if everything is correct an entry
16290 is added to the table containing priority specific dispatching entries
16291 for this compilation unit.
16292 (Delay_Config_Pragma_Analyze): Delay processing
16293 Priority_Specific_Dispatching pragmas because when processing the
16294 pragma we need to access run-time data, such as the range of
16295 System.Any_Priority.
16296 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
16297 Allow pragma Unreferenced as a context item
16298 Add pragma Preelaborable_Initialization
16299 (Analyze_Pragma, case Interface): Interface is extended so that it is
16300 now syntactically and semantically equivalent to Import.
16301 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
16302 insertion characters.
16303 Add handling for Pragma_Wide_Character_Encoding
16304 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
16305 never supercedes a real restriction, and that a real restriction
16306 always supercedes a warning.
16307 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

16314 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
16315 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
16316 Is_Inherently_Limited_Type, because return-by-reference has no meaning
16318 (Find_Node_To_Be_Wrapped): Use new method of determining the result
16319 type of the function containing a return statement, because the
16320 Return_Type field was removed. We now use the Return_Applies_To field.
16322 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
16323 (Build_Task_Image_Decl): If procedure is not called from an
16324 initialization procedure, indicate that function that builds task name
16325 uses the sec. stack. Otherwise the enclosing initialization procedure
16326 will carry the indication.
16327 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
16328 N_Object_Declaration instead.
16329 (Kill_Dead_Code): New interface to implement -gnatwt warning for
16330 conditional dead code killed, and change implementation accordingly.
16331 (Insert_Actions): Add N_Return_Object_Declaration case.
16332 Correct comment to mention N_Extension_Aggregate node.
16333 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
16334 attempts to save information for global variables which cannot be
16336 (Get_Current_Value_Condition): Handle conditions the other way round
16337 (constant on left). Also handle right operand of AND and AND THEN
16338 (Set_Current_Value_Condition): Corresponding changes
16339 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
16340 (Get_Current_Value_Condition): Handle simple boolean operands
16341 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
16342 (Get_Current_Value_Condition): If the variable reference is within an
16343 if-statement, does not appear in the list of then_statments, and does
16344 not come from source, treat it as being at unknown location.
16345 (Get_Current_Value_Condition): Enhance to allow while statements to be
16346 processed as well as if statements.
16347 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
16349 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
16350 of loop. This is safe now that we fixed Kill_Current_Values.
16351 (OK_To_Do_Constant_Replacement): Check whether current scope is
16352 Standard, before examining outer scopes.
16354 2006-10-31 Vincent Celier <celier@adacore.com>
16356 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
16357 When True, apply VMS treatment to children of packages A, G, I and S.
16360 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
16362 2006-10-31 Robert Dewar <dewar@adacore.com>
16363 Ed Schonberg <schonberg@adacore.com>
16365 * freeze.adb: Add handling of Last_Assignment field
16366 (Warn_Overlay): Supply missing continuation marks in error msgs
16367 (Freeze_Entity): Add check for Preelaborable_Initialization
16369 * g-comlin.adb: Add Warnings (Off) to prevent new warning
16371 * g-expect.adb: Add Warnings (Off) to prevent new warning
16373 * lib-xref.adb: Add handling of Last_Assignment field
16374 (Generate_Reference): Centralize handling of pragma Obsolescent here
16375 (Generate_Reference): Accept an implicit reference generated for a
16376 default in an instance.
16377 (Generate_Reference): Accept a reference for a node that is not in the
16378 main unit, if it is the generic body corresponding to an subprogram
16381 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
16383 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
16385 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
16387 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
16388 use clauses, to avoid messages on packages used to qualify, and also
16389 to avoid messages from obsolescent units.
16390 (Warn_On_Useless_Assignments): Don't generate messages for imported
16391 and exported variables.
16392 (Warn_On_Useless_Assignments): New procedure
16393 (Output_Obsolescent_Entity_Warnings): New procedure
16394 (Check_Code_Statement): New procedure
16396 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

16398 (Last_Assignment): New field for useless assignment warning
16400 2006-10-31 Olivier Hainque <hainque@adacore.com>
16402 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
16403 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
16405 2006-10-31 Bob Duff <duff@adacore.com>
16406 Robert Dewar <dewar@adacore.com>
16407 Ed Schonberg <schonberg@adacore.com>
16409 * g-awk.adb (Default_Session, Current_Session): Compile this file in
16410 Ada 95 mode, because it violates the new rules for AI-318.
16412 * g-awk.ads: Use overloaded subprograms in every case where we used to
16413 have a default of Current_Session. This makes the code closer to be
16414 correct for both Ada 95 and 2005.
16416 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
16417 code, relying on the fact that the compiler generates a warning
16418 instead of an error in -gnatg mode.
16420 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
16421 E_Return_Statement entity kind.
16422 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
16424 * par.adb (P_Interface_Type_Definition): Addition of one formal to
16425 report an error if the reserved word abstract has been previously found.
16426 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
16428 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
16429 parenthesized range attribute usage
16430 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
16432 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
16433 in the syntax for extended_return_statement. This is not in the latest
16434 RM, but the ARG is expected to issue an AI allowing this.
16435 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
16436 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
16437 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
16438 P_Return_Statement): Parse the new syntax for extended_return_statement.
16440 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
16441 Output_End_Missing): Add error-recovery code for the new
16442 extended_return_statement syntax; that is, the new E_Return entry on
16445 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
16446 limited to nonlimited, because otherwise we violate the new Ada 2005
16447 rules about returning limited types in function Create_AST_Handler in
16450 * sem.adb (Analyze): Add cases for new node kinds
16451 N_Extended_Return_Statement and N_Return_Object_Declaration.
16453 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
16454 type is in the same category as type of context before applying check,
16455 to prevent anomalies in instantiations.
16456 (Resolve_Aggregate): Remove test for limited components in aggregates.
16457 It's unnecessary in Ada 95, because if it has limited components, then
16458 it must be limited. It's wrong in Ada 2005, because limited aggregates
16460 (Resolve_Record_Aggregate): Move check for limited types later, because
16461 OK_For_Limited_Init requires its argument to have been resolved.
16462 (Get_Value): When copying the component default expression for a
16463 defaulted association in an aggregate, use the sloc of the aggregate
16464 and not that of the original expression, to prevent spurious
16465 elaboration errors, when the expression includes function calls.
16466 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
16467 were missing. We also didn't handle qualified expressions. Now also
16468 allow function calls. Use new common routine OK_For_Limited_Init.
16469 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
16470 with space can upper case letter).
16472 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
16473 Has_Static_Discriminants flag
16474 (Record_Type_Declaration): Diagnose an attempt to declare an interface
16475 type with discriminants.
16476 (Process_Range_Expr_In_Decl): Do validity checks on range
16477 (Build_Discriminant_Constraints): Use updated form of
16478 Denotes_Discriminant.
16479 (Process_Subtype): If the subtype is a private subtype whose full view
16480 is a concurrent subtype, introduce an itype reference to prevent scope
16482 (Build_Derived_Record_Type, Collect_Interface_Primitives,
16483 Record_Type_Declaration): The functionality of the subprograms
16484 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
16485 is now performed by a single routine.
16486 (Build_Derived_Record_Type): If the type definition includes an explicit
16487 indication of limitedness, then the type must be marked as limited here
16488 to ensure that any access discriminants will not be treated as having
16489 a local anonymous access type.
16490 (Check_Abstract_Overriding): Issue a detailed error message when an
16491 abstract subprogram was not overridden due to incorrect mode of its
16493 (Analyze_Private_Extension_Declaration): Add support for the analysis of
16494 synchronized private extension declarations. Verify that the ancestor is
16495 a limited or synchronized interface or in the generic case, the ancestor
16496 is a tagged limited type or synchronized interface and all progenitors
16497 are either limited or synchronized interfaces.
16498 Derived_Type_Declaration): Check for presence of private extension when
16499 dealing with synchronized formal derived types.
16500 Process_Full_View): Enchance the check done on the usage of "limited" by
16501 testing whether the private view is synchronized.
16502 Verify that a synchronized private view is completed by a protected or
16504 (OK_For_Limited_Init_In_05): New function.
16505 (Analyze_Object_Declaration): Move check for limited types later,
16506 because OK_For_Limited_Init requires its argument to have been resolved.
16507 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16508 in order to alleviate the upward compatibility introduced by AI-318.
16509 (Constrain_Corresponding_Record): If the constraint is for a component
16510 subtype, mark the itype as frozen, to avoid out-of-scope references to
16511 discriminants in the back-end.
16512 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
16513 this subprogram against wrong sources.
16514 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
16515 discriminant of limited type completed with a protected type, when the
16516 discriminant is used to constrain a private component of the type, and
16517 expansion is disabled.
16518 (Find_Type_Of_Object): Do not treat a return subtype that is an
16519 anonymous subtype as a local_anonymous_type, because its accessibility
16520 level is the return type of the enclosing function.
16521 (Check_Initialization): In -gnatg mode, turn the error "cannot
16522 initialize entities of limited type" into a warning.
16523 (OK_For_Limited_Init): Return true for generated nodes, since it
16524 sometimes violates the legality rules.
16525 (Make_Incomplete_Declaration): If the type for which an incomplete
16526 declaration is created happens to be the currently visible entity,
16527 preserve the homonym chain when removing it from visibility.
16528 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
16529 inherited subprograms.
16530 (Access_Definition): If this is an access to function that is the return
16531 type of an access_to_function definition, context is a type declaration
16532 and the scope of the anonymous type is the current one.
16533 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
16534 incomplete subtype to the set of private dependents of the original
16536 (Constrain_Discriminated_Type): Emit an error message whenever an
16537 incomplete subtype is being constrained.
16538 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
16539 corresponding subtype of the full view of the original incomplete type.
16540 (Check_Incomplete): Properly detect invalid usage of incomplete types
16543 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
16545 * g-catiio.ads, g-catiio.adb (Value): New function.

16554 Robert Dewar <dewar@adacore.com>
16556 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
16557 handling executable extension manually and duplicating code.
16559 * make.adb: Implement new -S switch
16560 (Gnatmake): Use new function Osint.Executable_Name instead
16561 of handling executable extension manually.
16563 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
16564 is specified, the executable name ends with this suffix.
16565 Take advantage of Osint.Executable_Name instead of duplicating code.
16567 * switch-m.adb: Recognize new gnatmake -S switch
16569 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
16571 (Get_Target_Parameters): Set Executable_Extension_On_Target if
16574 * makeusg.adb: Add line for gnatmake -S switch
16576 2006-10-31 Vincent Celier <celier@adacore.com>
16578 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
16579 call it with -static-libgcc, as there are some platforms, such as
16580 Darwin, where one of these two switches is compulsory to link.
16582 2006-10-31 Vincent Celier <celier@adacore.com>
16584 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
16585 instead of ADA_PROJECT_PATH, for the project path.
16586 (Gnatls): When displaying the project path directories, use host dir
16589 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
16590 names in the project path, as absolute paths may correspond to
16591 multi-valued VMS logical names.
16593 2006-10-31 Vincent Celier <celier@adacore.com>
16595 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
16596 absolute path name.
16597 (Locate_Regular_File): Ditto
16598 (Change_Dir): Remove, no longer used
16599 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
16600 on Windows. Get it calling Get_Current_Dir.
16601 (OpenVMS): Remove imported boolean, no longer needed.
16602 (Normalize_Pathname)[VMS]: Do not resolve directory names.
16603 (Pid_To_Integer): New function to convert a Process_Id to Integer
16605 2006-10-31 Thomas Quinot <quinot@adacore.com>
16607 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
16608 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
16610 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
16613 2006-10-31 Robert Dewar <dewar@adacore.com>
16615 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
16616 initial letter o as a zero.
16618 2006-10-31 Robert Dewar <dewar@adacore.com>
16620 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
16622 2006-10-31 Robert Dewar <dewar@adacore.com>
16624 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
16626 (Layout_Variant_Record): Retrieve the discriminants from the entity
16627 rather than from the type definition, because in the case of a full
16628 type for a private type we need to take the discriminants from the
16630 (Layout_Component_List): When applying the Max operator to variants with
16631 a nonstatic size, check whether either operand is static and scale that
16632 operand from bits to storage units before applying Max.
16633 (Layout_Type): In VMS, if a C-convention access type has no explicit
16634 size clause (and does not inherit one in the case of a derived type),
16635 then the size is reset to 32 from 64.
16637 2006-10-31 Vincent Celier <celier@adacore.com>
16639 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
16640 its file has already been loaded, according to the unit being loaded,
16641 not to the current value of Multiple_Unit_Index.
16643 2006-10-31 Thomas Quinot <quinot@adacore.com>
16644 Eric Botcazou <ebotcazou@adacore.com>
16645 Arnaud Charlet <charlet@adacore.com>
16647 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
16648 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
16650 (a-except.o): Pass it to the compiler.
16651 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
16652 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
16653 a-calend-mingw.adb version.

16656 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
16657 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
16658 Ada.Dispatching.Round_Robin.
16659 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
16661 * Make-lang.in: Remove all references to gt-ada-decl.h.
16662 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
16664 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
16665 Update dependencies.

16669 2006-10-31 Vincent Celier <celier@adacore.com>
16671 * mlib-utl.adb (Initialized): Remove, no longer used
16672 (Initialize): Remove, no longer used
16673 (Ar): If Ar_Exec is null, get the location of the archive builder and,
16674 if there is one, the archive indexer. Fail if the archive builder cannot
16676 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
16679 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16681 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
16682 Process_Body_Clauses): If the context of a body includes a use clause
16683 for P.Q then a with_clause for P in the same body is not redundant,
16684 even if the spec also has a with_clause on P.
16685 Add missing continuation mark to error msg
16686 (Build_Limited_Views): A limited view of a type is tagged if its
16687 declaration includes a record extension.
16688 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
16689 node, even if the subunit has errors. This avoids malfunction by
16690 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
16691 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
16692 generation of obsolescent messages for with statements (cannot do
16693 this too early, or we cannot implement avoiding the messages in the
16694 case of obsolescent units withing obsolescent units).
16695 (Install_Siblings): If the with_clause is on a remote descendant of
16696 an ancestor of the current compilation unit, find whether there is
16697 a sibling child unit that is immediately visible.
16698 (Remove_Private_With_Clauses): New procedure, invoked after completing
16699 the analysis of the private part of a nested package, to remove from
16700 visibility the private with_clauses of the enclosing package
16702 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
16703 now centralized in Generate_Reference.
16704 (Install_Limited_Context_Clauses): Remove superfluous error
16705 message associated with unlimited view visible through use
16706 and renamings. In addition, at the point in which the error
16707 is reported, we add the backslash to the text of the error
16708 to ensure that it is reported as a single error message.
16709 Use new // insertion for some continuation messages
16710 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
16711 to create implicit with_clause for parent unit mentioned in original
16712 limited_with_clause.
16713 (Install_Limited_With_Unit): Set entity of parent identifiers if the
16714 unit is a child unit. For ASIS queries.
16715 (Analyze_Subunit): If the subunit appears within a child unit, make all
16716 ancestor child units directly visible again.

16731 a formal object declaration with an access definition or a subtype mark
16732 with a null exclusion.
16733 (P_Generic_Association): Handle association with box, and others_choice
16734 with box, to support Ada 2005 partially parametrized formal packages.
16736 2006-10-31 Robert Dewar <dewar@adacore.com>
16737 Javier Miranda <miranda@adacore.com>
16739 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
16740 (P_Type_Declaration): Remove barrier against the reserved word "limited"
16741 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
16742 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
16743 private extensions.
16744 (P_Type_Declaration): Add the new actual Abstract_Present to every call
16745 to P_Interface_Type_Definition.
16746 (P_Interface_Type_Definition): Addition of one formal to report an error
16747 if the reserved word abstract has been previously found.
16748 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
16749 object renaming declaration with an access definition or subtype mark
16750 with a possible null exclusion.
16752 * par-ch9.adb: Minor error msg fix
16754 * par-load.adb: Add missing continuation mark to error msg
16756 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation
16758 2006-10-31 Vincent Celier <celier@adacore.com>
16760 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
16761 unknown attribute in unknown package or in package that does not need
16763 (Parse_Package_Declaration): Do not issue warning for unknown package in
16766 2006-10-31 Vincent Celier <celier@adacore.com>
16768 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
16769 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
16772 2006-10-31 Vincent Celier <celier@adacore.com>
16774 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
16775 on VMS, change "__" to '.' before checking the name.
16776 (Record_Ada_Source): Always add the source file name in the list of
16777 of sources, even if it is not the first time, as it is for another
16779 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
16780 dot, instead of replacing only the first '_'.
16782 * prj-part.adb (Parse): Convert project file path to canonical form
16784 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
16785 extended, the project id of the project extending it is recorded in its
16786 data, even when it has already been processed as an imported project.
16788 2006-10-31 Robert Dewar <dewar@adacore.com>
16790 * repinfo.adb (List_Entities): Don't list entities from renaming
16793 2006-10-31 Arnaud Charlet <charlet@adacore.com>
16794 Robert Dewar <dewar@adacore.com>
16796 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
16797 only a restriction warning is active for the given restriction. This is
16798 desirable because we do not want to modify code in the case where only
16800 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
16801 causes overriding of real restrictions.
16802 Take advantage of new No_Restrictions constant.
16804 * raise.h: (__gnat_set_globals): Change profile.
16806 2006-10-31 Arnaud Charlet <charlet@adacore.com>
16808 * rtsfind.adb: Remove s-polint from comment as it exists no more.
16811 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.

16831 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
16832 properly an attempt to apply Unchecked_Access to a protected operation.
16833 (OK_Self_Reference): New subprogram to check the legality of an access
16834 attribute whose prefix is the type of an enclosing aggregate.
16835 Generalizes previous mechanism to handle attribute references nested
16836 arbitrarily deep within the aggregate.
16837 (Analyze_Access_Attribute): An access attribute whose prefix is a type
16838 can appear in an aggregate if this is a default-initialized aggregate
16839 for a self-referential type.
16840 (Resolve_Attribute, case Access): Ditto.
16841 Add support for new implementation defined attribute Stub_Type.

16843 (Analyze_Attribute, case Attribute_Stub_Type): New case.
16844 (Stream_Attribute_Available): Implement using new subprogram from
16845 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
16846 Has_Specified_Stream_Attribute flag.
16847 Disallow Storage_Size and Storage_Pool for access to subprogram
16848 (Resolve_Attribute, case 'Access et al): Take into account anonymous
16849 access types of return subtypes in extended return statements. Remove
16850 accessibility checks on anonymous access types when Unchecked_Access is
16852 (Analyze_Attribute): Add support for the use of 'Class to convert
16853 a class-wide interface to a tagged type.
16854 Add support for the attribute Priority.
16855 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
16856 whether the designated type is discriminated with a constrained partial
16857 view and require static matching in that case.
16858 Add local variable Des_Btyp. The Designated_Type
16859 of an access to incomplete subtype is either its non-limited view if
16860 coming from a limited with or its etype if regular incomplete subtype.
16862 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
16863 Fix predicate to identify and allow cases of (expander-generated)
16864 references to tag of designated object of a RACW.
16865 (Validate_Static_Object_Name): In Ada 2005, a formal object is
16866 non-static, and therefore cannot appear as a primary in a preelaborable
16868 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
16869 Has_Read_Write_Attributes.
16870 (Has_Read_Write_Attributes): Reimplement in termes of
16871 Has_Stream_Attribute_Definition.
16872 (Missing_Read_Write_Attributes): When checking component types in a
16873 record, unconditionally call Missing_Read_Write_Attributes recursively
16874 (remove guard checking for Is_Record_Type / Is_Access_Type).
16876 2006-10-31 Robert Dewar <dewar@adacore.com>
16878 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
16879 useless assignments here and conditionalize it on absence of exception

16882 detection code, for new handling of formal packages.
16884 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16885 Hristian Kirtchev <kirtchev@adacore.com>
16887 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
16888 that has been constant-folded, preserve information of original tree,
16890 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
16891 generated private extension declaration if the formal derived type is
16892 synchronized. Carry synchronized present over to the generated private
16894 (Validate_Derived_Type_Instance): Ensure that the actual of a
16895 synchronized formal derived type is a synchronized tagged type.
16896 (Instantiate_Formal_Package): When creating the instantiation used to
16897 validate the actual package of a formal declared without a box, check
16898 whether the formal itself depends on a prior actual.
16899 (Instantiate_Formal_Subprogram): Create new entities for the defining
16900 identifiers of the formals in the renaming declaration, for ASIS use.
16901 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
16902 a renaming declaration or a subtype declaration for an actual in an
16903 instance, capture location information of declaration in generic, for
16905 (Instantiate_Formal_Package): Add comments on needed additional tests.
16906 AI-317 (partial parametrization) is fully implemented.
16907 (Validate_Private_Type_Instance): Add check for actual which
16908 must have preelaborable initialization
16909 Use new // insertion for some continuation messages
16910 (Analyze_Formal_Object_Declaration): Change usage of Expression to
16911 Default_Expression. Add type retrieval when the declaration has an
16912 access definition. Update premature usage of incomplete type check.
16913 (Check_Access_Definition): New subsidiary routine. Check whether the
16914 current compilation version is Ada 05 and the supplied node has an
16916 (Instantiate object): Alphabetize local variables. Handle the creation
16917 of new renaming declarations with respect to the kind of definition
16918 used - either an access definition or a subtype mark. Guard against
16919 unnecessary error message in the context of anonymous access types after
16920 they have been resolved. Add check for required null exclusion in a
16921 formal object declaration.
16922 (Switch_View): A private subtype of a non-private type needs to be
16923 switched (the base type can have been switched without its private
16924 dependents because of the last branch of Check_Private_View.
16925 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
16927 (Instantiate_Type): Emit an error message whenever a class-wide type of
16928 a tagged incomplete type is used as a generic actual.
16929 (Find_Actual_Type): Extend routine to handle a component type in a child
16930 unit that is imported from a formal package in a parent.
16931 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
16932 agree on constrainedness, rather than checking against ultimate ancestor
16933 (Instantiate_Subprogram_Body): Create a cross-reference link to the
16934 generic body, for navigation purposes.
16936 2006-10-31 Robert Dewar <dewar@adacore.com>
16937 Thomas Quinot <quinot@adacore.com>
16939 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
16941 (New_Stream_Subprogram): When processing an attribute definition clause
16942 for a stream-oriented subprogram, record an entity node occurring at
16943 the point of clause to use for checking the visibility of the clause,
16944 as defined by 8.3(23) as amended by AI-195.
16945 (New_Stream_Subprogram): New procedure, factoring behaviour from both
16946 New_Stream_Function and New_Stream_Procedure.
16947 (New_Stream_Function, New_Stream_Procedure): Removed.
16948 (Analyze_Attribute_Definition_Clause, case Address): Check new
16949 Alignment_Check check

16952 Javier Miranda <miranda@adacore.com>
16953 Robert Dewar <dewar@adacore.com>
16955 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
16956 generate the same errors compiling under -gnatc.
16957 (Try_Object_Operation): If no candidate interpretation succeeds, but
16958 there is at least one primitive operation with the right name, report
16959 error in call rather than on a malformed selected component.
16960 (Analyze_Selected_Component): If the prefix is an incomplete type from
16961 a limited view, and the full view is available, use the full view to
16962 determine whether this is a prefixed call to a primitive operation.
16963 (Operator_Check): Verify that a candidate interpretation is a binary
16964 operation before checking the type of its second formal.
16965 (Analyze_Call): Add additional warnings for function call contexts not
16967 (Analyze_Allocator): Move the check for "initialization not allowed for
16968 limited types" after analyzing the expression. This is necessary,
16969 because OK_For_Limited_Init looks at the structure of the expression.
16970 Before analysis, we don't necessarily know what sort of expression it
16971 is. For example, we don't know whether F(X) is a function call or an
16972 indexed component; the former is legal in Ada 2005; the latter is not.
16973 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
16974 were missing. We also didn't handle qualified expressions. Now also
16975 allow function calls. Use new common routine OK_For_Limited_Init.
16976 (Analyze_Type_Conversion): Do not perform some legality checks in an
16977 instance, because the error message will be redundant or spurious.
16978 (Analyze_Overloaded_Selected_Component): Do not do style check when
16979 setting an entity, since we do not know it is the right entity yet.
16980 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
16981 (Analyze_Overloaded_Selected_Component): Same change
16982 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
16983 since regular incomplete subtypes are transformed into corresponding
16984 subtypes of their full views.
16985 (Complete_Object_Operation): Treat name of transformed subprogram call
16986 as coming from source, for browsing purposes.
16987 (Try_Primitive_Operation): If formal is an access parameter, compare
16988 with base type of object to determine whether it is a primitive
16990 (Operator_Check): If no interpretation of the operator matches, check
16991 whether a use clause on any candidate might make the operation legal.
16992 (Try_Class_Wide_Operation): Check whether the first parameter is an
16993 access type whose designated type is class-wide.

17000 warn on infinite loops.
17001 Add \\ to some continuation messages
17002 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
17003 (Process_Bounds): If the bounds are integer literals that result from
17004 constant-folding, and they carry a user-defined type, preserve that type
17005 rather than treating this as an integer range.
17006 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
17007 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
17008 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
17009 left hand side of assignment.
17010 (Analyze_Assignment): Add suport to manage assigments to the attribute
17011 priority of a protected object.
17012 (Check_Possible_Current_Value_Condition): Allow fully qualified names
17013 not just identifiers.
17014 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
17015 or AND THEN for possible tracking.
17016 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
17017 case of while loops so we can track values in the loop body.

17020 Hristian Kirtchev <kirtchev@adacore.com>
17021 Bob Duff <duff@adacore.com>
17023 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
17024 procedure cannot be a protected operation (it is a basic_declaration,
17025 not a subprogram_declaration).
17026 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
17027 Subp. Add logic for entry processing.
17028 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
17029 Determine whether an entry or subprogram of a protected or task type
17030 override an inherited primitive of an implemented interface.
17031 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
17032 Update the actual used in calls to Check_Overriding_Indicator.
17033 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
17034 generate the proper reference to the parent unit, for cross-reference.
17035 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
17037 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17038 (Add_Extra_Formal): Revise procedure to allow passing in associated
17039 entity, scope, and name suffix, and handle setting of the new
17040 Extra_Formals field.
17041 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
17042 pass new parameters. Add support for adding the new extra access formal
17043 for functions whose calls are treated as build-in-place.
17044 (Analyze_A_Return_Statement): Correct casing in error message.
17045 Move Pop_Scope to after Analyze_Function_Return, because an extended
17046 return statement really is a full-fledged scope. Otherwise, visibility
17047 doesn't work right. Correct use of "\" for continuation messages.
17048 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
17049 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
17050 the node doesn't get properly marked as analyzed.
17051 (Analyze_Subprogram_Body): If subprogram is a function that returns
17052 an anonymous access type that denotes a task, build a Master Entity
17054 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
17055 proper usage of null exclusion in a result definition.
17056 (Process_Formals): Code cleanup and new error message.
17057 (Process_Formals): Detect incorrect application of null exclusion to
17059 (Conforming_Types): Handle conformance between [sub]types and itypes
17060 generated for entities that have null exclusions applied to them.
17061 (Maybe_Primitive_Operation): Add an additional type retrieval when the
17062 base type is an access subtype. This case arrises with null exclusions.
17063 (New_Overloaded_Entity): Do not remove the overriden entity from the
17064 homonym chain if it corresponds with an abstract interface primitive.
17065 (Process_Formals): Replace membership test agains Incomplete_Kind with a
17066 call to the synthesized predicate Is_Incomplete_Type.
17067 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
17069 (Analyze_Subprogram_Declaration): Check that abstract interface
17070 primitives are abstract or null.
17071 (Analyze_Subprogram_Specification): Remove previous check for abstract
17072 interfaces because it was not complete.
17073 (Has_Interface_Formals): Removed.

17076 Javier Miranda <miranda@adacore.com>
17078 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
17079 of Analyze_Package_Body, to create Itype references for anonymous
17080 access types created in the package declaration, whose designated types
17081 may have only a limited view.
17082 (Analyze_Package_Specification): For the private part of a nested
17083 package, install private_with_clauses of enclosing compilation unit if
17084 we are in its visible part.
17085 (Declare_Inherited_Private_Subprograms): Complete barrier
17086 to ensure that the primitive operation has an alias to some parent
17087 primitive. This is now required because, after the changes done for the
17088 implementation of abstract interfaces, the contents of the list of
17089 primitives has entities whose alias attribute references entities of
17090 such list of primitives.
17091 (Analyze_Package_Specification): Simplify code that handles parent units
17092 of instances and formal packages.
17093 (Uninstall_Declarations): Check the convention consistency among
17094 primitive overriding operations of a tagged record type.

17105 (Analyze_Generic_Renaming): Same fix
17106 (Use_One_Package): Do not take into account the internal entities of
17107 abstract interfaces during the analysis of entities that are marked
17108 as potentially use-visible.
17109 (Find_Type): Handle the case of an attribute reference for
17110 implementation defined attribute Stub_Type (simply let the analysis of
17111 the attribute reference rewrite it).
17112 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
17113 type that appears in a Use_Type clause.
17114 (Analyze_Object_Renaming): Add support for renaming of the Priority
17116 (Find_Type): In Ada 2005, a task type can be used within its own body,
17117 when it appears in an access definition.
17118 (Analyze_Object_Renaming): Remove warning on null_exclusion.
17119 (Analyze_Object_Renaming): Introduce checks for required null exclusion
17120 in a formal object declaration or in a subtype declaration.
17121 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
17122 (Check_Null_Exclusion): New local routine to
17123 Analyze_Subprogram_Renaming. Check whether the formals and return
17124 profile of a renamed subprogram have required null exclusions when
17125 their counterparts of the renaming already impose them.
17126 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
17127 Determine whether an entity is inside a generic scope.
17128 (In_Open_Scope): First pass of documentation update.
17129 (Find_Expanded_Name): Add support for shadow entities associated with
17130 limited withed packages. This is required to handle nested packages.
17131 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
17132 that makes a renaming of a limited withed package illegal.

17139 (Analyze_Task_Definition): Ditto.
17140 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
17141 (Check_Overriding_Indicator): To find overridden interface operation,
17142 examine only homonyms that have an explicit subprogram declaration, not
17143 inherited operations created by an unrelated type derivation.
17144 (Check_Overriding_Indicator): When checking for the presence of "null"
17145 in a procedure, ensure that the queried node is a procedure

17163 of a call to a function that dispatches on access result.
17164 (Check_Dispatching_Operation): In case of late overriding of a primitive
17165 that covers abstract interface subprograms we register it in all the
17166 secondary dispatch tables associated with abstract interfaces.
17167 (Check_Dispatching_Call): Add check that a dispatching call is not made
17168 to a function with a controlling result of a limited type. This is a
17169 current implementation restriction.
17170 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).

17172 argument is an interface type that is a generic formal.
17173 (Is_Interface_Subprogram): Removed.
17174 (Check_Dispatching_Operation): If the subprogram is not a dispatching
17175 operation, check the formals to handle the case in which it is
17176 associated with an abstract interface type.

17196 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
17197 subprogram type to provide better diagnostics in case of ambiguity.
17198 (Covers): Handle coverage of formal and actual anonymous access types in
17199 the context of generic instantiation.
17200 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
17201 abstract interface types; this is required to handle concurrent types
17202 with discriminants and abstract interface types.
17203 (Covers): Include type coverage of both regular incomplete subtypes and
17204 incomplete subtypes of incomplete type visibles through a limited with

17218 qualification from an expression. There are numerous places where this
17219 ought to be used, but we currently only deal properly with zero or one
17221 (In_Instance); The analysis of the actuals in the instantiation of a
17222 child unit is not within an instantiation, even though the parent
17223 instance is on the scope stack.

17989 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
17990 abstract interface type, the static analysis is not enough to know if

17992 we must pass the work to the expander to generate the required code to
17993 evaluate the conversion at run-time.
17994 (Resolve_Equality_Op): Do not apply previous
17995 transformation if expansion is disasbled, to prevent anomalies when

18694 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
18695 against errors in the source program: a private types for which the
18696 corresponding full type declaration is missing and pragma CPP_Virtual
18698 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
18699 (Is_Known_Null): New flag
18700 (Has_Pragma_Pure): New flag
18701 (No_Return): Present in all entities, set only for procedures
18702 (Is_Limited_Type): A type whose ancestor is an interface is limited if
18703 explicitly declared limited.
18704 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
18705 entities. Only used for component marked Is_Tag. If present it stores
18706 the Offset_To_Top function used to provide this value in tagged types
18707 whose ancestor has discriminants.
18709 * exp_ch2.adb: Update status of new Is_Known_Null flag
18711 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
18713 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
18714 the categorization sense if Is_Pure was set by pragma Pure_Function.
18716 2006-02-13 Quentin Ochem <ochem@adacore.com>
18717 Olivier Hainque <hainque@adacore.com>
18719 * bindusg.adb: Updated documentation for -d and -D switches.
18721 * raise.h (__gnat_set_globals): added new parameter for
18722 Default_Stack_Size.
18724 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
18725 (__gnat_handle_vms_condition): Adjust context before raise.
18726 (__gnat_install_handler): Restore the global vector setup for GCC
18727 versions before 3.4, as the frame based circtuitry is not available
18729 (__gnat_set_globals): added a parameter default_stack_size
18730 (__gl_default_stack_size): new variable.
18732 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18734 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
18735 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
18736 does not exist in the Ada RM.
18737 (Compatible_Int_Bounds): Determine whether two integer range bounds
18738 are of equal length and have the same start and end values.
18739 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
18740 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
18741 aggregate when it is part of an object declaration.
18742 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
18743 constrains discriminants of its parent, add explicitly the discriminant
18744 constraints of the ancestor by retrieving them from the
18745 stored_constraint of the parent.
18747 2006-02-13 Robert Dewar <dewar@adacore.com>
18749 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
18750 attribute Mechanism_Code is applied to renamed subprogram, modify
18751 prefix to point to base subprogram.
18752 Max/Min attributes now violate Restriction No_Implicit_Conditionals
18754 * sinfo.ads: Document that Mechanism_Code cannot be applied to
18755 renamed subprograms so that the front-end must replace the prefix
18758 2006-02-13 Javier Miranda <miranda@adacore.com>
18759 Gary Dismukes <dismukes@adacore.com>
18761 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
18762 availability of RE_Interface_Tag.
18763 (Build_Initialization_Call): Fix wrong access to the discriminant value.
18764 (Freeze_Record_Type): Do not generate the tables associated with
18765 timed and conditional dispatching calls through synchronized
18766 interfaces if compiling under No_Dispatching_Calls restriction.
18767 When compiling for Ada 2005, for a nonabstract
18768 type with a null extension, call Make_Controlling_Function_Wrappers
18769 and insert the wrapper function declarations and bodies (the latter
18770 being appended as freeze actions).
18771 (Predefined_Primitive_Bodies): Do not generate the bodies of the
18772 predefined primitives associated with timed and conditional
18773 dispatching calls through synchronized interfaces if we are
18774 compiling under No_Dispatching_Calls.
18775 (Build_Init_Procedure): Use RTE_Available to check if a run-time
18776 service is available before generating a call.
18777 (Make_Controlling_Function_Wrappers): New procedure.
18778 (Expand_N_Full_Type_Declaration): Create a class-wide master for
18779 access-to-limited-interfaces because they can be used to reference
18780 tasks that implement such limited interface.
18781 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
18782 procedure spec and body of the Offset_To_Top function that is generated
18783 when the parent of a type with discriminants has secondary dispatch
18785 (Init_Secondary_Tags): Handle the case in which the parent of the type
18786 containing secondary dispatch tables has discriminants to generate the
18787 correct arguments to call Set_Offset_To_Top.
18788 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
18790 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
18791 Add Wide_[Wide_]Expanded_Name.
18792 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
18793 the same functionality of Get_Prim_Op_Address but applied to predefined
18794 primitive operations because the pointers to the predefined primitives
18795 are now saved in a separate table.
18796 (Parent_Size): Modified to get access to the separate table of primitive
18797 operations or the parent type.
18798 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
18799 functionality of Set_Prim_Op_Address but applied to predefined primitive
18801 (Set_Signature): New subprogram used to store the signature of a DT.
18802 (Displace): If the Offset_To_Top value is not static then call the
18803 function generated by the expander to get such value; otherwise use
18804 the value stored in the table of interfaces.
18805 (Offset_To_Top): The type of the actual has been changed to Address to
18806 give the correct support to tagged types with discriminants. In this
18807 case this value is stored just immediately after the tag field.
18808 (Set_Offset_To_Top): Two new formals have been added to indicate if the
18809 offset_to_top value is static and hence pass this value to the run-time
18810 to store it in the table of interfaces, or else if this value is dynamic
18811 and then pass to the run-time the address of a function that is
18812 generated by the expander to provide this value for each object of the
18815 * rtsfind.ads (Default_Prin_Op_Count): Removed.
18816 (Default_Prim_Op_Count): New entity
18817 (Get_Predefined_Prim_Op_Address): New entity
18818 (Set_Predefined_Prim_Op_Address): New entity
18819 (RE_Set_Signature): New entity
18821 2006-02-13 Thomas Quinot <quinot@adacore.com>
18822 Ed Schonberg <schonberg@adacore.com>
18824 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
18825 Make_Adjust_Call done for a newly-allocated object.
18827 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
18828 in a subprogram are wrapped in a cleanup block, indicate that the
18829 subprogram contains an inner block with an exception handler.
18830 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
18831 Adjust call is for a newly-allocated object. In that case we must not
18832 assume that the finalization list chain pointers are correct (since they
18833 come from a bit-for-bit copy of the original object's pointers) so if
18834 the attach level would otherwise be zero (no change), we set it to 4
18835 instead to cause the pointers to be reset to null.
18837 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
18838 reset chain pointers to null.
18840 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18842 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
18843 string, and the context requires a loop for the assignment (e.g.
18844 because the left-hand side is packed), generate a unique name for the
18845 temporary that holds the string, to prevent spurious name clashes.
18847 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18848 Javier Miranda <miranda@adacore.com>
18849 Robert Dewar <dewar@adacore.com>
18850 Gary Dismukes <dismukes@adacore.com>
18852 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
18853 return unconstrained arrays.
18855 (Expand_Call): An indirect call through an access parameter of a
18856 protected operation is not a protected call.
18857 Add circuit to raise CE in Ada 2005 mode following call
18858 to Raise_Exception.
18859 (Register_DT_Entry): Do nothing if
18860 the run-time does not give support to abstract interfaces.
18861 (Freeze_Subprogram): In case of dispatching operations, do not generate
18862 code to register the operation in the dispatch table if the source
18863 is compiled with No_Dispatching_Calls.
18864 (Register_Predefined_DT_Entry): Generate code that calls the new
18865 run-time subprogram Set_Predefined_Prim_Op_Address instead of
18866 Set_Prim_Op_Address.
18868 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
18869 on array assignments if the right-hand side is a function call that has
18870 been inlined. Check is performed on the assignment in the block.
18871 (Process_Bounds): If bounds and range are overloaded, apply preference
18872 rule for root operations to disambiguate, and diagnose true ambiguity.
18873 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
18874 a tag-indeterminate right-hand side even when Expander_Active is True.
18875 Needed to ensure that dispatching calls to T'Input are allowed and
18876 get the tag of the target class-wide object.
18878 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
18879 an inherited primitive operation that already overrides several
18880 abstract interface primitives. For transitivity, the new entity must
18881 also override all the abstract interface primitives covered by the
18882 inherited overriden primitive.
18883 Emit warning if new entity differs from homograph in same scope only in
18884 that one has an access parameter and the other one has a parameter of
18885 a general access type with the same designated type, at the same
18886 position in the signature.
18887 (Make_Inequality_Operator): Use source locations of parameters and
18888 subtype marks from corresponding equality operator when creating the
18889 tree structure for the implicit declaration of "/=". This does not
18890 change anything in behaviour except that the decoration of the
18891 components of the subtree created for "/=" allows ASIS to get the
18892 string images of the corresponding identifiers.
18893 (Analyze_Return_Statement): Remove '!' in warning message.
18894 (Check_Statement_Sequence): Likewise.
18895 (Analyze_Subprogram_Body): For an access parameter whose designated type
18896 is an incomplete type imported through a limited_with clause, use the
18897 type of the corresponding formal in the body.
18898 (Check_Returns): Implicit return in No_Return procedure now raises
18899 Program_Error with a compile time warning, instead of beging illegal.
18900 (Has_Single_Return): Function returning unconstrained type cannot be
18901 inlined if expression in unique return statement is not an identifier.
18902 (Build_Body_To_Inline): It is possible to inline a function call that
18903 returns an unconstrained type if all return statements in the function
18904 return the same local variable. Subsidiary procedure Has_Single_Return
18905 verifies that the body conforms to this restriction.
18907 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
18908 same type, and one of them is of an anonymous access type, convert
18909 the other operand to it, so that this is a valid binary operation for
18911 (Resolve_Type_Conversion): Handle subtypes of protected types and
18912 task types when accessing to the corresponding record type.
18913 (Resolve_Allocator): Add '\' in 2-line warning message.
18914 Remove '!' in warning message.
18915 (Resolve_Call): Add '\' in 2-line warning message.
18916 (Valid_Conversion): Likewise.
18917 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
18918 resulting type may be an access type with an implicit dereference.
18919 Obtain the proper component from the designated type.
18920 (Make_Call_Into_Operator): Handle properly a call to predefined equality
18921 given by an expanded name with prefix Standard, when the operands are
18922 of an anonymous access type.
18923 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
18924 Explicit_Dereference and Resolve_Selected_Component, to verify that the
18925 prefix of the expression is not of an incomplete type. Allows full
18926 diagnoses of all semantic errors.
18927 (Resolve_Actuals): If the actual is an allocator whose directly
18928 designated type is a class-wide interface we build an anonymous
18929 access type to use it as the type of the allocator. Later, when
18930 the subprogram call is expanded, if the interface has a secondary
18931 dispatch table the expander will add a type conversion to force
18932 the displacement of the pointer.
18933 (Resolve_Call): If a function that returns an unconstrained type is
18934 marked Inlined_Always and inlined, the call will be inlined and does
18935 not require the creation of a transient scope.
18936 (Check_Direct_Boolean_Op): Removed
18937 (Resolve_Comparison_Op): Remove call to above
18938 (Resolve_Equality_Op): Remove call to above
18939 (Resolve_Logical_Op): Inline above, since this is only call.
18940 (Valid_Conversion): Handle properly conversions between arrays of
18941 convertible anonymous access types.
18944 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
18945 the literal in an unchecked conversion, because GCC 4.x needs a static
18946 value for a string bound.
18948 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18949 Hristian Kirtchev <kirtchev@adacore.com>
18951 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
18952 components of the corresponding record, take into account component
18953 definitions that are access definitions.
18954 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
18955 procedure is not considered a dispatching call and will be expanded
18958 2006-02-13 Javier Miranda <miranda@adacore.com>
18960 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
18961 controlling argument of the dispatching call is an abstract interface
18962 class-wide type then we use it directly.
18963 Check No_Dispatching_Calls restriction.
18964 (Default_Prim_Op_Position): Remove the code that looks for the last
18965 entity in the list of aliased subprograms. This code was wrong in
18967 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
18968 when the source is compiled with the No_Dispatching_Calls restriction.
18969 (Init_Predefined_Interface_Primitives): No need to inherit primitives
18970 if we are compiling with restriction No_Dispatching_Calls.
18971 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
18972 subprograms if we are compiling under No_Dispatching_Calls restriction.
18973 (Make_DT): Generate a dispatch table with a single dummy entry if
18974 we are compiling with the No_Dispatching_Calls restriction. In
18975 addition, in this case we don't generate code that calls to the
18976 following run-time subprograms: Set_Type_Kind, Inherit_DT.
18977 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
18978 of this subprogram if compiling with the No_Dispatching_Calls
18980 (Expand_Type_Conversion): Instead of using the actual parameter,
18981 the argument passed as parameter to the conversion function was
18982 erroneously referenced by the expander.
18983 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
18984 Set_Predefined_Primitive_Op_Address and Set_Signature.
18985 (Expand_Dispatching_Call): Generate call to
18986 Get_Predefined_Prim_Op_Address for predefined primitives.
18987 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
18988 predefined primitives.
18989 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
18990 primitives we reserve one dummy entry to ensure that the tag does not
18991 point to some memory that is associated with some other object. In
18992 addition, remove all the old code that generated the assignments
18993 associated with the signature of the dispatch table and replace them
18994 by a call to the new subprogram Set_Signature.
18995 (Set_All_DT_Position): Change the algorithm because now we have a
18996 separate dispatch table associated with predefined primitive operations.
18997 (Expand_Interface_Conversion): In case of non-static offset_to_top
18998 add explicit dereference to get access to the object after the call
18999 to displace the pointer to the object.
19000 (Expand_Interface_Thunk): Modify the generation of the actual used
19001 in the calls to the run-time function Offset_To_Top to fulfil its
19003 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
19005 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19007 * exp_dist.adb (Copy_Specification): For access parameters, copy
19008 Null_Exclusion flag, which will have been set for stream subprograms
19011 2006-02-13 Pascal Obry <obry@adacore.com>
19013 * expect.c (__gnat_expect_portable_execvp): New implementation. The
19014 previous implementation was using the C runtime spawnve routine but
19015 the corresponding wait was using directly the Win32 API. This was
19016 causing some times a lock when waiting for an event using
19017 WaitForSingleObject in __gnat_waitpid. This new implementation uses
19018 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
19019 API fixes this problem.
19021 2006-02-13 Robert Dewar <dewar@adacore.com>
19023 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
19026 2006-02-13 Thomas Quinot <quinot@adacore.com>
19028 * exp_pakd.ads: Fix typos in comments.
19030 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
19031 array reference that is an explicit dereference, mark the converted
19032 (packed) array reference as analyzed to prevent a forthcoming
19033 reanalysis from resetting its type to the original (non-packed) array
19036 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19037 Javier Miranda <miranda@adacore.com>
19038 Eric Botcazou <ebotcazou@adacore.com>
19040 * exp_util.ads, exp_util.adb (Find_Prim_Op,
19041 Is_Predefined_Primitive_Operation): When
19042 searching for the predefined equality operator, verify that operands
19043 have the same type.
19044 (Is_Predefined_Dispatching_Operation): Remove the code that looks
19045 for the last entity in the list of aliased subprograms. This code
19046 was wrong in case of renamings.
19047 (Set_Renamed_Subprogram): New procedure
19048 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
19049 Exp_Type constant computed when entering this subprogram.
19050 (Known_Null): New function
19051 (OK_To_Do_Constant_Replacement): New function
19052 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
19053 (Side_Effect_Free): An attribute reference 'Input is not free of
19054 side effect, unlike other attributes that are functions. (from code
19056 (Remove_Side_Effects): Expressions that involve packed arrays or records
19057 are copied at the point of reference, and therefore must be marked as
19058 renamings of objects.
19059 (Is_Predefined_Dispatching_Operation): Return false if the operation is
19060 not a dispatching operation.
19063 (Remove_Side_Effects): Lift enclosing type conversion nodes for
19064 elementary types in all cases.
19066 2006-02-13 Javier Miranda <miranda@adacore.com>
19068 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
19069 task types when accessing to the corresponding record type.
19070 Remove '!' in warning message.
19072 2006-02-13 Olivier Hainque <hainque@adacore.com>
19074 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
19075 to avoid useless and space inefficient overalignments on targets where
19076 Max_Alignment is larger than 16.
19078 2006-02-13 Pascal Obry <obry@adacore.com>
19080 * g-catiio.adb (Sec_Number): New type used to compute the number of
19081 seconds since 1-1-1970.
19082 (Image) [Natural]: The parameter was an Integer, as we can't deal with
19083 negative numbers (years, months...) it is better to have a Natural here.
19085 (Image) [Number]: Change parameter from Long_Integer to Number.
19086 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
19087 overflow for dates past year 2038.
19089 2006-02-13 Matthew Heaney <heaney@adacore.com>
19091 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
19094 2006-02-13 Arnaud Charlet <charlet@adacore.com>
19096 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
19098 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
19099 finalization can occur normally.
19101 2006-02-13 Vincent Celier <celier@adacore.com>
19103 * gnatcmd.adb (Rules_Switches): New table
19104 (Add_To_Rules_Switches): New procedure
19105 (GNATCmd): For command CHECK, put all options following "-rules" in the
19106 Rules_Switches table. Append these -rules switches after the -cargs
19109 2006-02-13 Robert Dewar <dewar@adacore.com>
19111 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
19112 These two cases were generating incorrect output, and if this unit
19113 was built with checks on, generated a discriminant mismatch constraint
19116 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19117 Robert Dewar <dewar@adacore.com>
19119 * lib-xref.adb (Get_Type_Reference): For a private type whose full
19120 view is an array type, indicate the component type as well, for
19121 navigation purposes.
19122 (Generate_Reference): Don't consider array ref on LHS to be a case
19123 of violating pragma Unreferenced.
19124 Do not give Ada 2005 warning except on real reference.
19126 2006-02-13 Vincent Celier <celier@adacore.com>
19128 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
19129 main source, add switch -mdebug-main=_ada_ so that the executable can
19130 be debugged by the standard VMS debugger.
19131 (Gnatmake): Set No_Main_Subprogram to True when there is no main
19132 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
19133 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
19134 of the last source, as the binding and linking phases are never
19136 Set all executable obsolete when rebuilding a library.
19138 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
19141 2006-02-13 Javier Miranda <miranda@adacore.com>
19144 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
19145 code to improve the error message reported when the program has
19146 declarations of abstract interface types and it is not compiled with
19147 the -gnat05 switch.
19148 (P_Access_Definition): Reorganize the code to improve the error

19218 (Check_Dispatching_Operation): Do not generate code to register the
19219 operation in the dispatch table if the source is compiled with
19220 restriction No_Dispatching_Calls.

19222 No_Return procedure with procedure that is not No_Return
19223 (Check_Dispatching_Call): Suppress the check for an abstract operation
19224 when the original node of an actual is a tag-indeterminate attribute
19225 call, since the attribute, which must be 'Input, can never be abstract.
19226 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
19227 call to the Input attribute (even when rewritten).
19228 (Propagate_Tag): Augment comment to indicate the possibility of a call
19229 to an Input attribute.

19243 2006-02-13 Javier Miranda <miranda@adacore.com>
19245 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
19246 handles default-initialized components to keep separate the management
19247 of this feature but also avoid the unrequired resolution and
19248 expansion of components that do not have partially initialized
19250 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
19251 (Check_Bounds): Likewise.
19252 (Check_Length): Likewise.
19254 2006-02-13 Javier Miranda <miranda@adacore.com>
19255 Ed Schonberg <schonberg@adacore.com>
19257 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
19258 abstract interface type call analyze_and_resolve to expand the type
19259 conversion into the corresponding displacement of the
19260 reference to the base of the object.
19261 (Eval_Attribute, case Width): For systems where IEEE extended precision
19262 is supported, the maximum exponent occupies 4 decimal digits.
19263 (Accessibility_Message): Add '\' in 2-line warning message.
19264 (Resolve_Attribute): Likewise.
19265 (case Attribute_Access): Significantly revise checks
19266 for illegal access-to-subprogram Access attributes to properly enforce
19267 the rules of 3.10.2(32/2).
19268 Diagnose use of current instance with an illegal attribute.
19270 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal

19275 (Type_Access_Level): The accessibility level of anonymous acccess types
19276 associated with discriminants is that of the current instance of the
19277 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
19278 (Compile_Time_Constraint_Error): Handle case of conditional expression.
19279 (Kill_Current_Values_For_Entity): New function

19286 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
19287 Analyze_Compilation_Unit.
19288 Detect and warn on redundant with clauses detected in a package spec
19289 and/or body when -gnatwr is used.
19290 (Analyze_Context): Analyze config pragmas before other items
19291 (Install_Context_Items): Don't analyze config pragmas here
19292 (Install_Limited_Withed_Unit): Set limited entity of package in
19293 with_clause so that cross-reference information or warning messages on
19294 unused packages can be properly generated
19295 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
19296 has Error_Posted set. Prevent infinite loops in illegal programs.
19297 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
19298 to the point of the error test requiring the current unit to be private.
19299 This ensures that private with clauses are not exempted from the basic
19300 checking for being a descendant of the same library unit parent as a
19301 withed private descendant unit.
19302 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
19303 handle private with clauses properly, as well as to account for cases
19304 where the withed unit is a public descendant of a private ancestor
19305 (in which case the current unit must be a descendant of the private
19306 ancestor's parent). The spec comments were updated accordingly. Also,
19307 the old error message in this subprogram was replaced with error
19308 messages that mirror the errors tested and reported by
19309 Check_Private_Child_Unit.
19310 Parameter and variable names improved for readability.
19311 (Install_Limited_Context_Clauses): Remove test for a withed unit being
19312 private as the precondition for calling
19313 Check_Private_Limited_Withed_Unit since that subprogram has been
19314 revised to test public units as well as private units.

19319 Javier Miranda <miranda@adacore.com>
19321 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
19322 that Scope_Stack.First = 1.
19323 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19324 were not always properly handled previously.
19325 (Formal_Entity): Complete rewrite, to handle properly some complex case
19326 with multiple levels of parametrization by formal packages.
19327 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
19328 to the corresponding derived type declaration for proper semantics.
19330 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
19331 (Check_Component): Enforce restriction on components of
19332 unchecked_unions: a component in a variant cannot contain tasks or
19334 (Unchecked_Union): Allow nested variants and multiple discriminants, to
19336 Add pragma Ada_2005 (synonym for Ada_05)
19337 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19338 were not always properly handled previously.
19339 Document that pragma Propagate_Exceptions has no effect
19340 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
19341 (Set_Convention_From_Pragma): Check that if a convention is
19342 specified for a dispatching operation, then it must be
19343 consistent with the existing convention for the operation.
19344 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
19345 longer required to specify an vtable-ptr component in the record. For
19346 compatibility reasons we leave the support for the previous definition.
19347 (Analyze_Pragma, case No_Return): Allow multiple arguments
19349 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
19350 non-overrideen inherited operation with a controlling result as
19351 illegal only its implicit declaration comes from the derived type
19352 declaration of its result's type.
19353 (Check_Possible_Deferred_Completion): Relocate the object definition
19354 node of the subtype indication of a deferred constant completion rather
19355 than directly analyzing it. The analysis of the generated subtype will
19356 correctly decorate the GNAT tree.
19357 (Record_Type_Declaration): Check whether this is a declaration for a
19358 limited derived record before analyzing components.
19359 (Analyze_Component_Declaration): Diagnose record types not explicitly
19360 declared limited when a component has a limited type.
19361 (Build_Derived_Record_Type): Code reorganization to check if some of
19362 the inherited subprograms of a tagged type cover interface primitives.
19363 This check was missing in case of a full-type associated with a private
19365 (Constant_Redeclaration): Check that the subtypes of the partial and the
19366 full view of a constrained deferred constant statically match.
19367 (Mentions_T): A reference to the current type in an anonymous access
19368 component declaration must be an entity name.
19369 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
19370 class_wide type to refer to full type, not to the incomplete one.
19371 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
19372 available. Required to give support to the certified run-time.
19373 (Analyze_Component_Declaration): In case of anonymous access components
19374 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
19375 (Process_Discriminants): For an access discriminant, use the
19376 discriminant specification as the associated_node_for_itype, to
19377 simplify accessibility checks.
19379 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19380 Javier Miranda <miranda@adacore.com>
19382 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
19383 abstract interpretations on an operator, remove interpretations that
19384 yield Address or a type derived from it, if one of the operands is an
19386 (Try_Object_Operation.Try_Primitive_Operation,
19387 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
19388 location when creating the new reference to a primitive or class-wide
19389 operation as a part of rewriting a subprogram call.
19390 (Try_Primitive_Operations): If context requires a function, collect all
19391 interpretations after the first match, because there may be primitive
19392 operations of the same type with the same profile and different return
19393 types. From code reading.
19394 (Try_Primitive_Operation): Use the node kind to choose the proper
19395 operation when a function and a procedure have the same parameter
19397 (Complete_Object_Operation): If formal is an access parameter and prefix
19398 is an object, rewrite as an Access reference, to match signature of
19399 primitive operation.
19400 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
19401 by an expanded name with prefix Standard, when the operands are of an
19402 anonymous access type.
19403 (Remove_Abstract_Operations): If the operation is abstract because it is
19404 inherited by a user-defined type derived from Address, remove it as
19405 well from the set of candidate interpretations of an overloaded node.
19406 (Analyze_Membership_Op): Membership test not applicable to cpp-class
19409 2006-02-13 Bob Duff <duff@adacore.com>
19411 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
19412 redundant use clauses.
19413 In particular, if the scope of two use clauses overlaps, but one is not
19414 entirely included in the other, we should not warn. This can happen
19415 with nested packages.
19416 (Analyze_Subprogram_Renaming): Protect the compiler against previously
19417 reported errors. The bug was reported when the compiler was built
19418 with assertions enabled.
19419 (Find_Type): If the node is a 'Class reference and the prefix is a
19420 synchronized type without a corresponding record, return the type
19423 2006-02-13 Javier Miranda <miranda@adacore.com>
19425 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
19426 if this is the full-declaration associated with a private declaration
19427 that implement interfaces, then the private type declaration must be
19429 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
19430 as aliased. The use of the 'access attribute is not available for such
19431 object (for this purpose the object should be explicitly marked as
19432 aliased, but being an anonymous type this is not possible).
19434 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19435 Robert Dewar <dewar@adacore.com>
19437 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
19438 compilation unit is an elaboration scope.
19439 (Add_Task_Proc): Add '\' in 2-line warning message.
19440 (Activate_All_Desirable): Deal with case of unit with'ed by parent
19442 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19443 Javier Miranda <miranda@adacore.com>
19445 * sem_type.adb (Write_Overloads): Improve display of candidate
19447 (Add_One_Interp): Do not add to the list of interpretations aliased
19448 entities corresponding with an abstract interface type that is an
19449 immediate ancestor of a tagged type; otherwise we have a dummy
19450 conflict between this entity and the aliased entity.
19451 (Disambiguate): The predefined equality on universal_access is not
19452 usable if there is a user-defined equality with the proper signature,
19453 declared in the same declarative part as the designated type.
19454 (Find_Unique_Type): The universal_access equality operator defined under
19455 AI-230 does not cover pool specific access types.
19456 (Covers): If one of the types is a generic actual subtype, check whether
19457 it matches the partial view of the other type.
19459 2006-02-13 Thomas Quinot <quinot@adacore.com>
19461 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
19462 line. This is necessary to allow In_Extended_Main_Unit to provide
19463 correct results for itypes while writing out expanded source.
19464 (Close_File): No need to update the source_index_table here since it's
19465 now done for each line.
19467 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19468 Robert Dewar <dewar@adacore.com>
19470 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
19471 preserve the source unit where the itype is declared, and prevent a
19473 (Note_Implicit_Run_Time_Call): New procedure
19474 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
19477 * sprint.ads: Document use of $ for implicit run time routine call
19479 2006-02-13 Quentin Ochem <ochem@adacore.com>
19481 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
19484 2006-02-13 Bob Duff <duff@adacore.com>
19486 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
19487 Scan_Unsigned, so we do not scan leading blanks and sign twice.
19488 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19489 raise Constraint_Error.
19491 * s-vallli.adb (Scan_Long_Long_Integer): Call
19492 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
19493 do not scan leading blanks and sign twice.
19494 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19495 raise Constraint_Error.
19497 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
19498 Scan_Long_Long_Unsigned): Split out most of the processing from
19499 Scan_Long_Long_Unsigned out into
19500 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
19501 This prevents scanning leading blanks and sign twice.
19502 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
19505 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
19506 out most of the processing from Scan_Unsigned out into
19507 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
19508 This prevents scanning leading blanks and sign twice.
19510 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
19511 use with Modular'Value attribute.
19512 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

19712 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
19713 link to the version that does nothing. This way the task termination

19715 because of an unhandled exception.
19717 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
19718 handler because of an unhandled exception.
19720 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

19733 instead for handling run-time termination in a more flexible way.
19734 (Adafinal_NT): This new procedure will take care of finalizing the
19735 global list for controlled objects if needed, but no tasking
19738 * s-tarest.adb (Task_Lock): Do not try to lock again the
19739 Global_Task_Lock if we already own it. Otherwise, we get blocked in
19740 some run-time operations.
19741 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
19742 until all nested locks have been released.
19743 (Task_Wrapper): Call the fall-back task termination handler. It

19751 moved to the Common_ATCB record.
19752 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
19753 Common_ATCB record.

19755 Common_ATCB record.
19757 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
19758 Fall_Back_Handler, and Specific_Handler.
19760 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
19761 defined in Ada.Task_Termination, to avoid circular dependencies.

19763 Ada.Task_Termination, for avoiding circular dependencies.
19764 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
19765 for storing task termination handlers. In addition,
19766 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
19767 Common_ATCB because it is used by both the regular and the restricted
19769 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
19770 Common_ATCB because it is used by both the regular and the restricted
19772 (Common_ATCB): Added a dynamic task analyzer field.

19780 using the soft links mechanism.
19781 (Task_Wrapper): added dynamic stack analysis.
19783 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
19784 potentially blocking operations has been moved from
19785 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
19786 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
19787 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
19788 this run-time check.
19790 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
19791 of task termination procedure.

19834 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
19835 to the specification because the frontend generates code that uses this
19837 (Set_Interface_Table): Add missing assertion.
19838 Update documentation describing the run-time structure.
19839 (Displace): New subprogram that displaces the pointer to the object
19840 to reference one of its secondary dispatch tables.
19841 (IW_Membership): Modified to use the new table of interfaces.
19842 (Inherit_TSD): Modified to use the new table of interfaces.

19860 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
19861 in all the calls to Expand_Interface_Thunk. Instead of referencing the
19862 record component containing the tag of the secondary dispatch table we
19863 have to use the Offset_To_Top run-time function to get this information;
19864 otherwise if the pointer to the base of the object has been displace
19865 we get a wrong value if we use the 'position attribute.
19867 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
19868 all the calls to Expand_Interface_Thunk.

19872 ensure that the interfaces implemented by the ancestors are placed
19873 at the header of the generated list.
19874 (Expand_Interface_Conversion): Handle the case in which the displacement
19875 associated with the interface conversion is not statically known. In
19876 this case we generate a call to the new run-time subprogram Displace.

19903 RE_TK_Tagged, RE_TK_Task.
19905 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
19906 Init_Secondary_Tags_Internal to allow its use with interface types and
19907 also to generate the code for the new additional actual required
19908 by Set_Offset_To_Top.
19909 (Build_Init_Statements): In case of components associated with abstract
19910 interface types there is no need to generate a call to its IP.

19921 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
19922 properly protected objects and attach handler in the case of the
19923 restricted profile.

19936 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
19937 pointer initialization values. Make a SAVE_EXPR instead. Add comments
19938 about the use and expansion of SAVE_EXPRs in the various possible
19939 renaming handling cases.
19940 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
19941 abusing DECL_FCONTEXT.

20038 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
20039 and the assignment to a class-wide object, before the assignment we
20040 generate a run-time check to ensure that the tag of the Target is
20041 covered by the tag of the source.

20112 (Derived_Type_Declaration): If the parent of the full-view is an
20113 interface perform a transformation of the tree to ensure that it has
20114 the same parent than the partial-view. This simplifies the job of the
20115 expander in order to generate the correct object layout, and it is
20116 needed because the list of interfaces of the full-view can be given in
20118 (Process_Full_View): The parent of the full-view does not need to be
20119 a descendant of the parent of the partial view if both parents are
20121 (Analyze_Private_Extension_Declaration): If declaration has an explicit
20122 "limited" the parent must be a limited type.
20123 (Build_Derived_Record_Type): A derived type that is explicitly limited
20124 must have limited ancestor and progenitors.
20125 (Build_Derived_Type): Ditto.
20126 (Process_Full_View): Verify that explicit uses of "limited" in partial
20127 and full declarations are consistent.

20130 implemented interfaces by a type.
20131 (Contain_Interface): New function used to check whether an interface is
20133 (Find_Hidden_Interface): New function used to determine whether two
20134 lists of interfaces constitute a set equality. If not, the first
20135 differing interface is returned.
20136 (Process_Full_View): Improve the check for the "no hidden interface"
20137 rule as defined by AI-396.

20152 source on the command line, call gnatcheck with all the compilable
20153 sources of the project.
20154 Take into account the new command Check, for gnatcheck. Treat as for
20155 other ASIS tools: take into account project, specific package Check and

20196 available user-specified stream attributes on limited parameters to
20197 also test the type directly rather than only its underlying type (for
20198 Ada 95) and, in the case of Ada 2005, to check that the user-specified
20199 attributes are visible at the point of the subprogram declaration.
20200 For Ada 2005, the error message is modified to indicate that the
20201 type's stream attributes must be visible (again, only for -gnat05).

20233 types use the corresponding record type. This was not needed before
20234 the implementation of Ada 2005 synchronized types because
20235 concurrent types were never tagged types in Ada 95.

20363 * socket.c: Add extern int h_errno for rtems since networking header
20364 files are not available at this point in a tool bootstrap. Newlib

20485 it did not matter because we always rewrote a/=b to not(a=b).
20486 (Expand_Allocator_Expression): For an allocator expression whose nominal
20487 subtype is an unconstrained packed type, convert the expression to its
20488 actual constrained subtype.

20509 Allow optional = after -gnatm
20510 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
20511 longer sets Elaboration_Checks.
20512 Code to set warning mode moved to Sem_Warn
20513 so that it can be shared by pragma processing.
20515 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

20635 from a fat or thin pointer type and a constrained object type.
20636 (annotate_value): Handle BIT_AND_EXPR.
20637 (annotate_rep): Don't restrict the back annotation of inherited
20638 components to the type_annotate_only case.
20639 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
20640 we are not defining the type.
20641 <E_Record_Type>: Likewise.
20642 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
20643 to get advantage of the new maybe_stabilize_reference interface, to
20644 ensure that what we reference is indeed stabilized instead of relying
20645 on assumptions on what the stabilizer does.
20646 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
20647 type imported through a limited_with clause, use its non-limited view.
20648 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
20650 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
20651 of #if sections + explicit comparisons of convention identifiers.

20653 before early-returning for certain types when code generation is
20655 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
20656 nullification of gnu_expr we do for objects with address clause and
20657 that we are not defining.
20658 (elaborate_expression_1): Do not create constants when creating
20659 variables needed by the debug info: the dwarf2 writer considers that
20660 CONST_DECLs is used only to represent enumeration constants, and emits
20662 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
20663 object with an address clause into an indirect reference, drop the
20664 initializing expression.
20666 (STACK_CHECK_BUILTIN): Delete.
20667 (STACK_CHECK_PROBE_INTERVAL): Likewise.

20675 if there is an actual subtype provided by the front-end, use that
20676 subtype to build an actual type with bounds template.
20677 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
20678 is provided by the front-end, use that subtype to compute the size of
20679 the deallocated object.
20680 (gnat_to_gnu): When adding a statement into an elaboration procedure,
20681 check for a potential violation of a No_Elaboration_Code restriction.

20683 with extra arguments to control whether to recurse through non-values
20684 and to let the caller know if the stabilization has succeeded.

20686 maybe_stabilize, for common uses without restriction on lvalues and
20687 without need to check for the success indication.
20688 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
20689 pass false instead of 0 as the FORCE argument which is a bool.
20690 (Identifier_to_gnu): Remove checks ensuring that an renamed object
20691 attached to a renaming pointer has been properly stabilized, as no such
20692 object is attached otherwise.
20693 (call_to_gnu): Invoke create_var_decl to create the temporary when the
20694 function uses the "target pointer" return mechanism.
20695 Reinstate conversion of the actual to the type of the formal
20696 parameter before any other specific treatment based on the passing
20697 mechanism. This turns out to be necessary in order for PLACEHOLDER
20698 substitution to work properly when the latter type is unconstrained.
20700 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
20702 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
20703 with extra arguments to control whether to recurse through non-values
20704 and to let the caller know if the stabilization has succeeded.
20706 * utils2.c (gnat_build_constructor): Only sort the fields for possible
20707 static output of record constructor if all the components are constant.
20708 (gnat_build_constructor): For a record type, sort the list of field
20709 initializers in increasing bit position order.
20710 Factor common code to build a storage type for an unconstrained object
20711 from a fat or thin pointer type and a constrained object type.
20712 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
20713 types variants, and process special cases of VIEW_CONVERT expressions
20714 as their NOP_EXPR counterpart to ensure we get to the
20715 CORRESPONDING_VARs associated with CONST_DECls.
20716 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
20717 on the right-hand side.
20719 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
20721 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
20722 are converting back to its original type.
20723 (convert) <JM input>: Fallthrough regular conversion code instead of
20724 extracting the object if converting to a type variant.
20725 (create_var_decl): When a variable has an initializer requiring code
20726 generation and we are at the top level, check for a potential violation
20727 of a No_Elaboration_Code restriction.
20728 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
20729 SIZE and SIZE_UNIT which we need for later back-annotations.

20731 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
20732 is an unchecked union.
20733 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
20734 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
20735 main variant, just replace the VIEW_CONVERT_EXPR.

20914 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
20915 'Unrestricted_Access, if the designated type is an interface we
20916 add a type conversion to force the displacement of the pointer
20917 to the secondary dispatch table.
20918 Use Universal_Real instead of Long_Long_Float when we need a high
20919 precision float type for the generated code (prevents gratuitous
20920 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
20921 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
20922 'Terminated for task interface class-wide objects. Generate a call to
20923 the predefined dispatching routine used to retrieve the _task_id from
20924 a task corresponding record.

20953 the return value into its actual subtype in order to help the backend
20954 to return the actual size instead of the maximum. This is another

20982 2005-11-14 Robert Dewar <dewar@adacore.com>
20984 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

21004 attribute of the N_Free_Statement.
21005 Generate itype for classwide designated object in both cases of
21006 user-specified storage pool: specific and class-wide, not only in the
21008 Raise CE when trying to set a not null access type object to null.

21270 (Build_Derived_Record_Type): Relax the condition that controls the
21271 execution of the check that verifies that the partial view and

21281 (Process_Full_View): Rename local subprogram Find_Interface_In_
21282 Descendant to Find_Ancestor_Interface to leave the code more clear.
21283 Remove wrong code that avoids the generation of an error message

21285 In addition some minor reorganization of the code has been done to
21286 leave it more clear.
21287 (Analyze_Type_Declaration): If type has previous incomplete tagged
21288 partial view, inherit properly its primitive operations.

21302 be included in the interface list.
21303 (Access_Definition): If the designated type is an interface that may
21304 contain tasks, create Master_Id for it before analyzing the expression
21305 of the declaration, which may be an allocator.

21333 Change name Is_Package to Is_Package_Or_Generic_Package
21334 (Preserve_Full_Attributes): For a synchronized type, the corresponding

21340 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
21341 not try to rewrite a renamed stream attribute, because the operations
21342 on the type may not have been generated.
21343 Handle properly a renaming_as_body generated for a stream operation
21344 whose default is abstract because the object type itself is abstract.
21345 (Find_Type): If the type is incomplete and appears as the prefix of a
21346 'Class reference, it is tagged, and its list of primitive operations
21347 must be initialized properly.
21348 (Chain_Use_Clauses): When chaining the use clauses that appear in the
21349 private declaration of a parent unit, prior to compiling the private
21350 part of a child unit, find on the scope stack the proper parent entity
21351 on which to link the use clause.
21352 (Note_Redundant_Use): Emit a warning when a redundant use clause is
21354 (Analyze_Object_Renaming): An attribute reference is not a legal object

21373 entry renaming or a primitive of a limited interface.
21374 (Valid_Conversion): If the operand has a single interpretation do not
21375 remove address operations.
21376 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
21377 statement to inhibit warning.
21378 (Resolve_Unary_Op): Do not produce a warning when
21379 processing an expression of the form -(A mod B)
21380 Use Universal_Real instead of Long_Long_Float when we need a high

21382 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
21383 (Resolve_Concatenation_Arg): Improve error message when argument is an
21384 ambiguous call to a function that returns an array.
21385 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

22360 Hristian Kirtchev <kirtchev@adacore.com>
22361 Javier Miranda <miranda@adacore.com>
22363 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
22364 from object notation, the original node is unanalyzed and carries no
22365 semantic information, so that accessiblity checks must be performed on
22366 the type of the actual itself.
22367 (Expand_N_Subprogram_Declaration): Change last actual parameter for
22368 compatibility with Build_Protected_Sub_Specification.
22369 (Check_Overriding_Inherited_Interfaces): Add suport to handle
22370 overloaded primitives.
22371 (Register_Interface_DT_Entry): Use the new name of the formal
22372 the the calls to Expand_Interface_Thunk

22375 include the generation of dispatching subprograms when the type
22376 implements at least one interface.
22378 * lib.ads: Extend information in Load_Stack to include whether a given
22379 load comes from a Limited_With_Clause.
22381 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
22382 whether a potential circularity is harmless, because it includes units
22383 loaded through a limited_with clause. Extends previous treatment which
22384 did not handle properly arbitrary combinations of limited and
22385 non-limited clauses.
22387 2005-09-01 Nicolas Setton <setton@adacore.com>
22389 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
22390 to be encoded as typ___XBLU_lowerbound__upperbound instead of
22391 typ___XB_lowerbound__upperbound.

22395 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
22396 dummy access formal for RACW/RAS TypeCode TSS.
22397 (Build_TypeCode_Call): Do not generate dummy null access actual for
22398 calls to the TypeCode TSS.
22400 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22402 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
22403 fully qualified name, to distinguish instances with the same local name.
22405 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
22408 2005-09-01 Robert Dewar <dewar@adacore.com>

22417 (Close): Deallocate any existing filter for the concerned connection
22419 2005-09-01 Laurent Pautet <pautet@adacore.com>
22421 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
22422 position set is provided, we compute one in order to reduce the maximum
22423 length of the keys. This computation first selects a character
22424 position between 1 and the minimum length of the keys in order to
22425 avoid reducing one of the keys to an empty string.
22426 (Initialize, Compute): When the ratio V to K is too low, the algorithm
22427 does not converge. The initialization procedure now comes with a
22428 maximum number of iterations such that when exceeded, an exception is
22429 raised in Compute. The user can initialize this ratio to another value
22431 Reformating and updated headers.
22433 2005-09-01 Javier Miranda <miranda@adacore.com>
22435 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
22436 that given an entity T creates and returns an Itype that duplicates the
22437 contents of T. The returned Itype has the null-exclusion
22438 attribute set to True, and its Etype attribute references T
22439 to keep the association between the two entities.
22440 Update copyright notice
22442 * sem_aggr.adb (Check_Can_Never_Be_Null,
22443 Aggregate_Constraint_Checks, Resolve_Aggregate,
22444 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
22446 * sem_ch5.adb (Analyze_Assignment): Code cleanup.
22448 2005-09-01 Gary Dismukes <dismukes@adacore.com>
22449 Robert Dewar <dewar@adacore.com>
22450 Hristian Kirtchev <kirtchev@adacore.com>

22463 (P_Access_Type_Definition): Add parsing for an anonymous access result
22464 subtype, plus parsing for null exclusions. Call Set_Result_Definition
22465 instead of Set_Subtype_Mark.
22467 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
22468 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
22469 (Result_Definition): New function for N_Function_Specifications.
22470 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
22471 N_Function_Specification.
22472 (Set_Null_Exclusion_Present): Allow this flag for
22473 N_Function_Specification.
22474 (Set_Result_Definition): New procedure for N_Function_Specifications.
22475 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
22476 and N_Function_Specification.
22478 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
22479 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
22480 Add support for LIMITED NEW for Ada 2005 AI-419
22481 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
22482 syntax for anonymous access results.

22494 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
22496 2005-09-01 Vincent Celier <celier@adacore.com>
22498 * lib-writ.adb: Update Copyright notice
22499 (Write_With_Lines): On platforms where file names are case-insensitive,
22500 record the file names in lower case.
22501 (Write_ALI): For D lines, on platforms where file names are
22502 case-insensitive, record the file names in lower case.
22504 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22505 Emmanuel Briot <briot@adacore.com>

22527 * par-prag.adb: Implement new pragma Debug_Policy
22529 * sem_prag.adb Implement new pragma Debug_Policy
22530 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
22531 Component_Size attribute specification. Give warning for ignored pragma
22534 * snames.h, snames.ads, snames.adb: Introduce entries in
22535 Preset_Names for Name_Disp_Asynchronous_Select,
22536 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
22537 Name_Disp_Timed_Select.
22538 New pragma Debug_Policy
22540 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
22542 Switch -gnata also sets Debug_Pragmas_Enabled
22544 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
22545 handle an explicit -gnata when compiling predefined files.
22547 2005-09-01 Vincent Celier <celier@adacore.com>
22549 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
22550 directories of projects that have no Ada sources.
22552 2005-09-01 Robert Dewar <dewar@adacore.com>
22554 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
22555 (makes a difference for wide characters)
22557 * widechar.adb, widechar.ads:
22558 Add Wide_Char_Byte_Count feature to count chars vs bytes
22560 2005-09-01 Thomas Quinot <quinot@adacore.com>
22561 Ed Schonberg <schonberg@adacore.com>
22562 Robert Dewar <dewar@adacore.com>
22564 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
22565 'Address attribute reference with an overloaded prefix, use the
22566 location of the prefix (not the location of the attribute reference) as
22567 the error location.
22568 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
22569 a function renaming thereof, is a valid prefix for 'Size (where it is
22570 intepreted as a function call).
22571 (Statically_Denotes_Entity): New predicate to determine whether the
22572 prefix of an array attribute can be considered static.
22575 (Eval_Attr): Fix failure to evaluate Component_Size for
22576 unconstrained arrays (resulted in wrong value in packed case, since
22577 back end cannot handle this case)
22579 2005-09-01 Robert Dewar <dewar@adacore.com>
22581 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
22582 error msgs for most common cases.
22583 Use new errout insertion char < (conditional warning)
22585 2005-09-01 Javier Miranda <miranda@adacore.com>
22586 Ed Schonberg <schonberg@adacore.com>
22588 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
22589 become local to the whole package.
22590 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
22591 the package was already analyzed the new algorithm "replaces" the
22592 real entities by the shadow ones. This is required to ensure that
22593 the order of these entities in the homonym chains does not change;
22594 otherwise we can have undefined references at linking time because
22595 in case of conflicts the external name of the entities will have
22596 a suffix that depends on the order of the entities in the chain.
22597 (Remove_Limited_With_Clause): Complementary code that completes the
22598 new algorithm and replaces the shadow entities by the real ones.
22599 (Install_Limited_Withed_Unit): When unchaining entities before the
22600 installation of the shadow entities, only regular entities of the
22601 public part must be taken into account. This is required to
22602 keep this routine in synch with the work done by Remove_Limited_
22604 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
22605 even if unit is analyzed, because the analysis of the unit is
22606 idempotent in any case, and the limited view of the unit may have to
22607 be installed for proper visibility.
22608 (Expand_Limited_With_Clause): Even if the unit in the implicit
22609 with_clause has been analyzed already, a limited view of the package
22610 must be built for the current context, if it does not exist yet.
22612 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22613 Javier Miranda <miranda@adacore.com>
22614 Gary Dismukes <dismukes@adacore.com>
22616 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
22617 defining entity for the instance body, make a new defining identifier
22618 rather than copying the entity of the spec, to prevent accidental
22619 sharing of the entity list.
22620 (Check_Private_View): When exchanging views of private types, build the
22621 list of exchanged views as a stack, to ensure that on exit the exchanges
22622 are undone in the proper order.
22623 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
22624 Restore the compilation environment in case of instantiation_error.
22625 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
22626 for an anonymous access result.
22627 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
22628 (Formal_Entity): Handle properly the case of a formal package that
22629 denotes a generic package renaming.
22631 2005-09-01 Thomas Quinot <quinot@adacore.com>
22633 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
22634 clause if the array aggregate is surrounded by parentheses.
22636 2005-09-01 Cyrille Comar <comar@adacore.com>
22637 Gary Dismukes <dismukes@adacore.com>
22638 Ed Schonberg <schonberg@adacore.com>
22639 Javier Miranda <miranda@adacore.com>
22641 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
22643 to check if a type is Constrained in cases related to code generation
22644 (rather than semantic checking) since otherwise we do not generate
22645 similar code for mutable private types depending if their
22646 discriminants are visible or not.
22647 (Check_Abstract_Overriding): Do not complain about failure to override
22648 the primitive operations used in dispatching selects since they will
22649 always be overriden at the freeze point of the type.
22650 (Access_Definition): Separate out handling for resetting the scope
22651 of an anonymous access function result type. Retrieve the scope
22652 of the associated function rather than using Current_Scope, which
22653 does not have a consistent value (depends on whether we're in the
22654 middle of analyzing formal parameters). Add ??? comment about
22655 finding a cleaner way to handle the special cases of scope setting.
22656 (Process_Incomplete_Dependents): A protected operation is never a
22657 dispatching operation (only its wrapper may be).
22658 (Build_Derived_Record_Type): In case of tagged private types that
22659 implement interfaces add derivation of predefined primitive
22661 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
22662 by two parameters that are used in case of derivation from abstract
22663 interface types: No_Predefined_Prims is used to avoid the derivation
22664 of predefined primitives from the interface, and Predefined
22665 Prims_Only is used to complete the derivation predefined primitives
22666 in case of private tagged types implementing interfaces.
22667 Fix typo in comments
22668 (Find_Interface_In_Descendant): Protect the frontend against
22669 wrong code with large circularity chains.
22670 (Is_Private_Overriding): Add support for entities overriding interface
22671 subprograms. The test failed because Entities associated with overriden
22672 interface subprograms are always marked as hidden (and used to build
22673 the secondary dispatch table); in this case the overriden entity is
22674 available through the field abstract_interface_alias (cf. override_
22675 dispatching_operation)
22676 (Access_Definition): Set the scope of the type to Current_Scope for the
22677 case of a function with an anonymous access result type.
22678 (Access_Subprogram_Declaration): Handle creation of the type entity for
22679 an access-to-function type with an anonymous access result.
22680 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
22681 in handling for N_Access_Function_Definition.
22682 (Analyze_Subtype_Declaration): Modify the text of error message.
22683 (Derived_Type_Declaration): Modify the text of error message.
22684 (Process_Subtype): Modify the text of error message plus cleanup
22685 of one redundant error message.
22686 (Analyze_Component_Declaration): Code cleanup.
22687 (Analyze_Object_Declaration): Code cleanup.
22688 (Analyze_Subtype_Declaration): Propagate the null-exclusion
22689 attribute in case of access types. Code cleanup.
22690 (Array_Type_Declaration): Code cleanup.
22691 (Process_Discriminants): Create the new null-excluding itype
22692 if required. Code cleanup.
22693 (Process_Subtype): Create the new null-excluding itype if
22694 required. Code cleanup.
22695 (Build_Derived_Record_Type): Code cleanup to avoid calling
22696 twice the subprogram derive_subprograms in case of private
22697 types that implement interfaces. In this particular case the
22698 subprogram Complete_Subprograms_Derivation already does the
22699 job associated with the second call.
22701 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
22702 conversion to the full view when generating an operation for a
22703 discriminant whose type may currently be private.
22705 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22706 Javier Miranda <miranda@adacore.com>
22708 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
22709 V (Obj.F), the rewriting does not involve the indexed component, but
22710 only the selected component itself.
22711 Do not apply the transformation if the analyzed node is an actual of a
22712 call to another subprogram.
22713 (Complete_Object_Operation): Retain the entity of the
22714 dispatching operation in the selector of the rewritten node. The
22715 entity will be used in the expansion of dispatching selects.
22716 (Analyze_One_Call): Improve location of the error message associated
22718 (Analyze_Selected_Component): No need to resolve prefix when it is a
22719 function call, resolution is done when parent node is resolved, as
22721 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
22722 when attempting to resolve a call transformed from its object notation.
22723 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
22724 of the argument list for each interpretation of the operation.
22725 (Try_Object_Operation): The designated type of an access parameter may
22726 be an incomplete type obtained through a limited_with clause, in which
22727 case the primitive operations of the type are retrieved from its full
22729 (Analyze_Call): If this is an indirect call, and the return type of the
22730 access_to_subprogram is incomplete, use its full view if available.
22732 2005-09-01 Javier Miranda <miranda@adacore.com>
22733 Gary Dismukes <dismukes@adacore.com>
22735 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
22736 access types the null-exclusion and access-to-constant attributes must
22738 (Analyze_Return_Statement): When the result type is an anonymous access
22739 type, apply a conversion of the return expression to the access type
22740 to ensure that appropriate accessibility checks are performed.
22741 (Analyze_Return_Type): For the case of an anonymous access result type,
22742 generate the Itype and set Is_Local_Anonymous_Access on the type.
22743 Add ??? placeholder for check to disallow returning a limited object
22744 in Ada 2005 unless it's an aggregate or a result of a function call.
22745 Change calls from Subtype_Mark to Result_Definition.
22746 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
22747 Result_Definition in call to Make_Function_Specification.
22748 (Build_Body_To_Inline): Change Set_Subtype_Mark to
22749 Set_Result_Definition.
22750 (Make_Inequality_Operator): Change formal Subtype_Mark to
22751 Result_Definition in call to Make_Function_Specification.
22752 (Process_Formals): Create the new null-excluding itype if required.
22753 (New_Overloaded_Entity): For an entity overriding an interface primitive
22754 check if the entity also covers other abstract subprograms in the same
22755 scope. This is required to handle the general case, that is, overriding
22756 other interface primitives and overriding abstract subprograms inherited
22757 from some abstract ancestor type.
22758 (New_Overloaded_Entity): For an overriding entity that comes from
22759 source, note the operation that it overrides.
22760 (Check_Conformance, Type_Conformant): Addition of one new formal
22761 to skip controlling formals in the analysis. This is used to
22762 handle overloading of abstract interfaces.
22763 (Base_Types_Match): Add missing case for types imported from
22764 limited-with clauses
22765 (New_Overloaded_Entity): Add barrier to protect the use of
22766 the "alias" attribute.
22768 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22770 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
22771 verify that the procedure and the entry are mode conformant.
22772 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
22773 as a different operator, which is often a cut-and-paste error.
22775 2005-09-01 Javier Miranda <miranda@adacore.com>
22776 Ed Schonberg <schonberg@adacore.com>
22778 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
22779 used in controlling parameters exclude null because it is necessary to
22780 read the tag to dispatch, and null has no tag.
22781 (Override_Dispatching_Operation): If the previous operation is inherited
22782 from an interface, it becomes hidden and does not participate in later
22785 2005-09-01 Javier Miranda <miranda@adacore.com>
22786 Ed Schonberg <schonberg@adacore.com>
22787 Gary Dismukes <dismukes@adacore.com>
22789 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
22790 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
22791 the expander will generate the corresponding run-time check to evaluate
22793 (Resolve_Call): Check for legal type of procedure name or prefix that
22794 appears as a trigger in a triggering alternative.
22795 (Valid_Conversion): If expression is ambiguous and the context involves
22796 an extension of System, remove System.Address interpretations.
22797 (Resolve_Qualified_Expression): Reject the case of a specific-type
22798 qualification applied to a class-wide argument. Enhance comment
22799 to explain checking of Original_Node.
22800 (Resolve_Type_Conversion): The location of the error message was not
22801 general enough to handle the general case and hence it has been removed.
22802 In addition, this patch improves the text of the message.
22803 (Resolve_Type_Conversion): Add missing support for access to interface
22805 (Resolve_Type_Conversion): If the target is a class-wide interface type,
22806 do not expand if the expression is the actual in a call, because proper
22807 expansion will take place when the call itself is expanded.
22808 (Resolve_Allocator): If the context is an unchecked conversion, the
22809 allocator inherits its storage pool, if any, from the target type of
22812 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22813 Javier Miranda <miranda@adacore.com>
22815 * sem_type.adb (Add_One_Interp): If a candidate operation is an
22816 inherited interface operation that has an implementation, use the
22817 implementation to avoid spurious ambiguities.
22818 (Interface_Present_In_Ancestor): In case of concurrent types we can't
22819 use the Corresponding_Record_Typ attribute to look for the interface
22820 because it is set by the expander (and hence it is not always
22821 available). For this reason we traverse the list of interfaces
22822 (available in the parent of the concurrent type).
22823 (Interface_Present_In_Ancestor): Handle entities from the limited view
22825 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22827 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
22828 from the list of required components.
22829 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
22830 primitive procedure of a limited interface with a controlling first
22832 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
22834 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
22835 capture if it is generated in the second operand of a short-circuit
22837 Do not capture values for variables with address clauses.
22838 (Is_Object_Reference): Treat a function call as an object reference only
22839 if its type is not Standard_Void_Type.
22841 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22843 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
22844 to a variable that is statically known to be constant.

22861 Document new treatment of wide characters in max line length
22863 Remove -gnatL/-gnatZ switches, no longer used.
22864 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

22868 Float_Representation.
22869 Add documentation for pragma No_Strict_Aliasing

23065 expression is a discriminant reference and its type is private, as can
23066 happen within a stream operation for a mutable record, use the full
23067 view of the type to resolve the case alternatives.

23095 clause, each parent must be loaded as a limited unit as well.
23097 * sem_ch10.adb (Previous_Withed_Unit): Better name for
23098 Check_Withed_Unit. Return true if there is a previous with_clause for
23099 this unit, whether limited or not.
23100 (Expand_Limited_With_Clause): Do not generate a limited_with_clause on
23102 (Is_Visible_Through_Renamings): New local subprogram of install_limited
23103 _withed_unit that checks if some package installed through normal with
23104 clauses has a renaming declaration of package whose limited-view is
23105 ready to be installed. This enforces the check of the rule 10.1.2 (21/2)
23106 of the current Draft document for Ada 2005.
23107 (Analyze_Context): Complete the list of compilation units that
23108 are allowed to contain limited-with clauses. It also contains
23109 checks that were previously done by Install_Limited_Context_Clauses.
23110 This makes the code more clear and easy to maintain.
23111 (Expand_Limited_With_Clause) It is now a local subprogram of
23112 Install_Limited_Context_Clauses, and contains the code that adds

23624 Arnaud Charlet <charlet@adacore.com>
23626 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
23627 longer protected objects. They have been replaced by lower-level
23628 suspension objects made up by a mutex and a condition variable (or
23629 their equivalent given a particular OS) plus some internal data to
23630 reflect the state of the suspension object.
23631 (Initialize, Finalize): Add this initialization procedure for
23632 Suspension_Object, which is a controlled type.
23633 (Finalize): Add the finalization procedure for Suspension_Object,
23634 which is a controlled type.
23636 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

23643 (InitializeCriticalSection, EnterCriticalSection,
23644 LeaveCriticalSection, DeleteCriticalSection): Replace the type
23645 pCriticalSection by an anonymous access type so that we avoid problems
23646 of accessibility to local objects.

23652 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
23653 set the environment task mask here.
23654 (Current_State): Add this function that returns the state of the
23656 (Set_False): Add this procedure that sets the state of the suspension
23658 (Set_True): Add this procedure that sets the state of the suspension
23659 object to True, releasing the task that was suspended, if any.
23660 (Suspend_Until_True): Add this procedure that blocks the calling task
23661 until the state of the object is True. Program_Error is raised if
23662 another task is already waiting on that suspension object.
23663 (Initialize): Add this procedure for initializing the suspension
23664 object. It initializes the mutex and the condition variable which are
23665 used for synchronization and queuing, and it sets the internal state
23667 (Finalize): Add this procedure for finalizing the suspension object,
23668 destroying the mutex and the condition variable.

23673 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
23674 which provides a low-level abstraction (using operating system
23675 primitives) for Ada.Synchronous_Task_Control.
23676 This object is made up by a mutex (for ensuring mutual exclusion), a
23677 condition variable (for queuing threads until the condition is
23678 signaled), a Boolean (State) indicating whether the object is open,
23679 and a Boolean (Waiting) reflecting whether there is a task already
23680 suspended on this object.

23832 type given in the allocator's expression is not deeper than the level
23833 of the allocator's access type.
23835 (Tagged_Membership): Modified to gives support to abstract interface
23838 * a-tags.ads, a-tags.adb (type Type_Specific_Data): Add component
23840 (Descendant_Tag): New predefined function

23843 (Set_Access_Level): New private procedure
23844 (IW_Membership): New function. Given the tag of an object and the tag
23845 associated with an interface, evaluate if the object implements the
23847 (Register_Interface_Tag): New procedure used to initialize the table of
23848 interfaces used by the IW_Membership function.

23855 (Parent_Tag): Return No_Tag in the case of a root-level tagged type,
23856 and raise Tag_Error if the passed tag equalis No_Tag, to conform with
23857 Ada 2005 semantics for the new predefined function.
23859 * exp_attr.adb (Expand_N_Attribute, case Attribute_Input): Generate
23860 call to Descendant_Tag rather than Internal_Tag.
23861 (Expand_N_Attribute, case Attribute_Output): Emit a check to ensure that
23862 the accessibility level of the attribute's Item parameter is not deeper
23863 than the level of the attribute's prefix type. Tag_Error is raised if
23864 the check fails. The check is only emitted for Ada_05.
23865 (Find_Stream_Subprogram): If a TSS exists on the type itself for the
23866 requested stream attribute, use it.
23867 (Expand_N_Attribute_Reference): If the designated type is an interface

24122 way as a normal component of an anonymous access type.
24123 (Resolve_Allocator): When an allocator's designated type is a class-wide
24124 type, check that the accessibility level of type given in the

24145 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
24146 check on possible violation of restriction No_Direct_Boolean_Operators

25104 (check dos line terminator).
25105 (Check_Line_Max_Length): New procedure, split off from the existing
25106 Check_Line_Terminator routine. Separating this out allows -gnatyf to
25107 be properly recognized.
25109 * styleg.adb: Add ??? comment for line terminator reference
25111 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

25152 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
25153 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
25154 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
25155 analyzed if expansion is disabled (which could otherwise cause spurious
25156 error messages if expansion has been disabled due to previous
25157 (unrelated) errors).
25159 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
25160 is disabled, the entity denoted by the argument is the access type
25161 itself, not an underlying record type, so there is no need to go back
25162 to the Corresponding_Remote_Type.
25164 2005-03-29 Gary Dismukes <dismukes@adacore.com>
25165 Robert Dewar <dewar@adacore.com>

25171 check is also generated, to ensure that the tag passed to the instance
25172 denotes a type in the class.
25173 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
25174 of Name_Generic_Dispatching_Constructor.
25176 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
25177 05 unit for AI-260-02).

25191 the case of renaming of stream attributes when the renaming denotes a
25192 generic formal subprogram association for an abstract formal subprogram.
25193 Check that the attribute is a primitive stream attribute (and not
25194 a class-wide stream attribute) and then rewrite the attribute name
25195 as the name of the appropriate compiler-generated stream primitive.
25197 2005-03-29 Robert Dewar <dewar@adacore.com>
25199 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

25206 * freeze.adb (Freeze_Record_Type): If the type of the component is an
25207 itype whose parent is controlled and not yet frozen, do not create a
25208 freeze node for the itype if expansion is disabled.
25210 2005-03-29 Vincent Celier <celier@adacore.com>
25212 * make.adb (Gnatmake): Don't fail if the main project file is declared
25213 as having no Ada sources. Do not display message "no sources to
25214 compile" in quiet output.
25216 2005-03-29 Doug Rupp <rupp@adacore.com>
25218 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

25229 missing TYPE Improve the error message generated when compiling a
25230 limited interface in Ada83 or Ada95 mode.
25232 2005-03-29 Robert Dewar <dewar@adacore.com>
25234 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
25235 rather than proceed ahead using a junk attribute name.
25237 2005-03-29 Vincent Celier <celier@adacore.com>
25239 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
25241 * prj-part.adb (Parse_Single_Project): Set the location of a project
25242 on its defining identifier, rather than on the reserved word "project".
25244 * prj-proc.adb (Expression): Adapt to the fact that default of external
25245 references may be string expressions, not always literal strings.
25246 (Recursive_Process): Set Display_Name equal to Name
25247 when Location is No_Location, that is when there is no actual file.
25248 Get the Display_Name of the project from the source, when it is not a
25250 (Process): Use the Display_Name in error messages
25252 * prj-strt.adb (External_Reference): Allow default to be string
25253 expressions, not only literal strings.
25255 2005-03-29 Vincent Celier <celier@adacore.com>
25257 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
25258 file and the reference symbol file to be the same file.
25260 2005-03-29 Thomas Quinot <quinot@adacore.com>
25262 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
25263 forbid conversion of a local access-to-subprogram type to a remote one.
25265 * sem_util.adb (Wrong_Type): For a record type that is the expanded
25266 equivalent type for a remote access-to-subprogram type, go back to the
25267 original RAS entity when displaying an error message, so the casing is
25268 the original source casing.
25270 2005-03-29 Robert Dewar <dewar@adacore.com>
25272 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
25275 2005-03-29 Ed Schonberg <schonberg@adacore.com>
25277 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
25278 subtype if code is being pre-analyzed, to prevent un-expanded
25279 references to protected formals, among others.
25280 (Analyze_Explicit_Dereference): If the overloaded prefix includes some

25770 (Post_Parse_Context_Clause): When specifying the project node of a with
25771 clause, indicate that it is a limited with only if there is "limited"
25772 in the with clause, not necessarily when In_Limited is True.

25807 2005-03-15 Olivier Hainque <hainque@adacore.com>
25809 * s-intman-posix.adb (Notify_Exception): Adjust signature, as handler
25810 for sigactions with SA_SIGINFO set. Call
25811 __gnat_adjust_context_for_raise before raising, to perform the
25812 potentially required adjustments to the machine context for the GCC
25815 * raise.h (__gnat_adjust_context_for_raise): New prototype.
25817 * init.c (__gnat_adjust_context_for_raise) HPUX: Initial revision.
25818 Adjust PC by one in the provided machine context.
25819 (__gnat_install_handler) HPUX: Set SA_SIGINFO in the sigaction flags,
25820 so that the handler is passed the context structure to adjust prior to

25823 SA_SIGINFO sigaction should look like. Call
25824 __gnat_adjust_context_for_raise before actually raising.
25825 (__gnat_adjust_context_for_raise): Default noop to help PC
25826 adjustments before raise from signal handlers.
25827 (__gnat_error_handler): Indirectly call a predicate function to
25828 determine if a condition should be resignaled or not.

25857 a-stwiun.ads, a-stwiun.adb, a-strunb.ads, a-strunb.adb: Move
25858 Realloc_For_Chunk to private part of package.
25859 New subprograms for AI-301
25861 * a-szuzti.adb, a-suteio.adb, a-swuwti.adb: Improve efficiency of
25862 Get_Line procedure.
25863 Avoid unnecessary use of Get/Set_Wide_String
25865 2005-03-15 Robert Dewar <dewar@adacore.com>
25868 * a-stunau.ads, a-stunau.adb:
25869 Change interface to allow efficient (and correct) implementation
25870 The previous changes to allow extra space in unbounded strings had
25871 left this interface a bit broken.
25873 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
25875 * g-spipat.ads, g-spipat.adb: New interface for Get_String

25912 This is only a documentation change, since it always worked to apply
25913 this to other than composite types (yielding false), but now this is
25915 Update documentation on Must_Be_Byte_Aligned for new spec
25917 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
25918 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
25919 uses of the Access_Disp_Table attribute to reference the first dispatch
25920 table associated with a tagged type. As
25921 part of the implementation of abstract interface types,
25922 Access_Disp_Table has been redefined to contain a list of dispatch
25923 tables (rather than a single dispatch table).
25924 Similarly, upgrade all the references to Tag_Component by the
25925 new attribute First_Tag_Component.
25926 (Find_Inherited_TSS): Moved to exp_tss.
25927 Clean up test in Expand_N_Object_Declaration for cases
25928 where we need to do a separate assignment of the initial value.

25930 declaration of a tagged type is an aggregate, no need to generate an
25931 additional tag assignment.
25932 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
25934 Bit packed array ops are only called if operands are known to be
25936 (Component_Equality): When returning an N_Raise_Program_Error statement,
25937 ensure that its Etype is set to Empty to avoid confusing GIGI (which
25938 expects that only expressions have a bona fide type).
25939 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
25940 determine the amount of data to be copied.
25942 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
25943 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

25967 derived type definition nodes.
25968 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
25969 (Task_Present, Set_Task_Present): New subprogram.
25970 (Task_Body_Procedure): Removed.
25971 (Set_Task_Body_Procedure): Removed.
25972 These subprogram have been removed because the attribute
25973 Task_Body_Procedure has been moved to the corresponding task type
25974 or task subtype entity to leave a field free to store the list
25975 of interfaces implemented by a task (for AI-345)
25976 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
25977 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
25978 expression flag Do_Range_Check
25979 (Exception_Junk): Change to Flag7 to accomodate above change
25980 (Box_Present, Default_Name, Specification, Set_Box_Present,
25981 Set_Default_Name, Set_Specification): Expand the expression
25982 "X in N_Formal_Subprogram_Declaration" into the corresponding
25983 two comparisons. Required to use the csinfo tool.

25986 "with string" given.
25988 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
25991 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
25994 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
25995 attribute Task_Body_Procedure rather than the old semantic field that
25996 was available in the task_type_declaration node.
25998 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
25999 interface type definitions.
26000 (P_Formal_Derived_Type_Definition): Modified to handle the list of
26003 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
26004 task type declaration.

26006 protected type declaration.
26008 2005-03-15 Doug Rupp <rupp@adacore.com>
26009 Vincent Celier <celier@adacore.com>
26011 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
26012 (Gen_Output_File_C): Likewise.
26013 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
26015 2005-03-15 Thomas Quinot <quinot@adacore.com>
26017 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
26018 is an N_Raise_Constraint_Error node, create a new copy of it without
26019 going through a call to Duplicate_Subexpr.

26024 Ed Schonberg <schonberg@adacore.com>
26030 * decl.c (gnat_to_gnu_field): Reject aliased components with a
26031 representation clause that prescribes a size not equal to the rounded
26032 size of their types.
26033 (gnat_to_gnu_entity, case E_Component): Always look at
26034 Original_Record_Component if Present and not the entity.
26035 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
26036 of tagged extension types by not making field for components that are
26038 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
26039 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
26040 expression to the type of the object when the object is constant.
26041 Reverse defer_debug_incomplete_list before traversing it, so that trees
26042 are processed in the order at which they were added to the list. This
26043 order is important when using the stabs debug format.
26044 If we are deferring the output of debug information, also defer this
26045 output for a function return type.
26046 When adding fields to a record, prevent emitting debug information
26047 for incomplete records, emit the information only when the record is
26049 (components_to_record): New parameter defer_debug.
26050 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
26051 (gnat_to_gnu_field_decl): New function.

26053 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
26054 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
26055 No longer update discriminants to not be a COMPONENT_REF.
26056 (copy_alias_set): Strip padding from input type; also handle
26057 unconstrained arrays properly.
26059 * gigi.h (write_record_type_debug_info): New function.
26060 Convert to use ANSI-style prototypes. Remove unused
26061 declarations for emit_stack_check, elab_all_gnat and

26063 (gnat_to_gnu_field_decl): New decl.
26065 * utils.c (write_record_type_debug_info): New function.

26069 (update_pointer_to): Fix pasto.
26070 (convert) <UNION_TYPE>: Accept slight type variations when
26071 converting to an unchecked union type.
26073 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
26074 replace the N_Freeze_Entity with a null statement.
26076 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
26077 within a constrained subcomponent of an enclosing record, place the
26078 freeze nodes in the scope stack entry for the enclosing record.

26080 (Set_Small_Size): Pass T, the type to modify; all callers changed.
26081 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
26082 within records; allow them to have freeze nodes if their base types
26085 * exp_util.adb (Remove_Side_Effects): Properly test for
26086 Expansion_Delayed and handle case when it's inside an
26087 N_Qualified_Expression.
26089 * sem_ch3.adb (Derived_Type_Declaration): New predicate
26090 Comes_From_Generic, to recognize accurately that the parent type in a
26091 derived type declaration can be traced back to a formal type, because
26092 it is one or is derived from one, or because its completion is derived
26094 (Constrain_Component_Type): If component comes from source and has no
26095 explicit constraint, no need to constrain in in a subtype of the
26097 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
26098 Minor change to propagate Is_Ada_2005 flag
26100 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
26101 Expansion_Delayed is False.
26102 (assoc_to_constructor): Ignore fields that have a
26103 Corresponding_Discriminant.
26104 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
26105 function returns "by target", dereference the target pointer using the
26106 type of the actual return value.
26107 <all>: Be prepared for a null gnu_result.
26108 (processed_inline_subprograms): Check flag_really_no_inline
26109 instead of flag_no_inline.

26119 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
26120 Must_Be_Byte_Aligned for cases where we do not need to use a
26121 System.Pack_nn unit.
26123 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
26125 Needed now that we do some processing for IN parameters as well. This
26126 may well fix some unrelated errors.
26127 (Expand_Call): Handle case of unaligned objects (in particular those
26128 that come from packed arrays).
26129 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
26130 renamed entity is an inherited operation, re-expand the call using the
26131 original operation, which is the one to call.
26132 Detect attempt to inline parameterless recursive subprogram.
26133 (Represented_As_Scalar): Fix to work properly with private types
26134 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
26135 accurate estimate. Yields True in far fewer cases than before,
26136 improving the quality of code that depends on this test.
26138 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
26139 over both visible and private declarations to remove them from tree,
26140 and mark subprograms declared in package as eliminated, to prevent
26141 spurious use in subsequent compilation of generic units in the context.
26143 * exp_util.ads: Minor cleanup in variable names
26145 * sem_eval.ads, sem_eval.adb: Minor reformatting
26146 (Compile_Time_Known_Bounds): New function

26150 * exp_ch7.adb (Convert_View): Use base types of underlying types when
26151 determining whether an unchecked conversion is needed for the argument
26152 of an initialization call.
26154 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26156 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
26157 that appears in the instantiation rather than the internal subtype
26158 generated in the wrapper package, to avoid anomalies in gigi when the
26159 target is derived from a private type whose full view is an access type.
26161 2005-03-15 Robert Dewar <dewar@adacore.com>
26163 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
26165 Add documentation to replace the use of this flag
26166 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
26169 2005-03-15 Thomas Quinot <quinot@adacore.com>
26171 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
26172 here from exp_attr so it can be shared between exp_attr and exp_dist.
26173 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
26174 all TSS names, not a subset thereof, and the previous name introduced
26175 an unnecessarily confusion that a distinction might exist between
26176 "OK" TSS names and some "not OK" TSS names.
26178 2005-03-15 Doug Rupp <rupp@adacore.com>
26180 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
26183 2005-03-15 Pascal Obry <obry@adacore.com>
26184 Eric Botcazou <ebotcazou@adacore.com>
26188 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
26189 when IN_RTS. This is to work around a bootstrap path problem.
26191 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
26192 table and pass it to __gnat_install_SEH_handler().
26193 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
26195 * lang.opt: Fix specification of -fRTS=.

26199 Vincent Celier <celier@adacore.com>
26200 Arnaud Charlet <charlet@adacore.com>
26203 This change works fine when gnatlib is built from the gcc directory,
26204 but does not work when using the libada Makefile, since GCC_FOR_TARGET
26205 is not passed to ada/Makefile.in, so more work is needed by a
26206 Makefile/configure expert.
26208 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
26209 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
26210 Setup gnatlink switch -M for x86_64 linux, as it is already setup
26212 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
26213 Run ranlib on libgccprefix.a
26214 Define PREFIX_OBJS for Darwin, to build libgccprefix.
26215 (ADA_INCLUDE_SRCS): Split Ada packages.
26217 2005-03-15 Robert Dewar <dewar@adacore.com>
26219 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
26221 * impunit.adb: Add GNAT.UTF_32
26223 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
26225 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
26226 now uses GNAT.UTF_32).
26228 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
26229 capabilities for categorizing characters using Unicode categories
26231 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26233 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
26234 instantiation that has been rewritten as a package body, retrieve spec
26235 to generate proper name for implicit_with_clause.
26236 (Install_Parents): Recognize a parent that is an instantiation but has
26237 been rewritten as a package declaration during analysis.

26242 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
26243 parameter reported some error we immediately return. This improves the
26244 behaviour of the frontend in case of errors.
26245 (Install_Parent, Remove_Parent): Introduce new flag
26246 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
26247 ancestor of a generic child unit, when the child is being instantiated.
26248 (Inline_Instance_Body): If we are compiling the private
26249 part or the body of a child unit, restore the proper visibility of the
26250 parents after compiling the instance body.
26252 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26253 Javier Miranda <miranda@adacore.com>
26256 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
26257 of a private type, in which case it is underlying_type that denotes
26258 the proper task. Also modified to use the new entity attribute
26259 that is directly available in the task type and task subtype entities
26260 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
26261 arrays when other dimensions than the first are constrained by
26262 discriminants of an enclosing record.
26263 (Insert_Explicit_Dereference): If the prefix is an indexed component or
26264 a combination of indexed and selected components, find ultimate entity
26265 and generate the appropriate reference for it, to suppress spurious
26267 (Note_Possible_Modification): If an entity name has no entity, return.
26268 (Is_Variable): A function call never denotes a variable.
26269 (Requires_Transient_Scope): For record types, recurse only on
26270 components, not on internal subtypes that may have been generated for
26271 constrained components.

26279 expansion is disabled (as when compiling a generic) to prevent spurious
26280 warnings on prefixes of selected components.
26282 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26284 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
26285 attached to a list before checking whether it appears in the private
26286 declarations of the current package.
26287 (Make_Inequality_Operator): Insert declaration in proper declarative
26288 list rather than just setting the Parent field, so that
26289 Is_Private_Declaration can handle it properly.
26291 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26293 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
26294 a renaming a body, check that the renamed subprogram in not intrinsic.
26295 (Find_Direct_Name): If several use_visible entities hide
26296 each other, and the context is a predefined file compiled through
26297 rtsfind, keep only the entity that comes from a predefined file.
26299 2005-03-15 Geert Bosch <bosch@adacore.com>
26301 * s-fatgen.adb (Valid): Extend special exceptions to account for long

26720 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
26721 wrong null-exclusion value by a warning message.
26722 (Enable_Range_Check): Do range check if the prefix is an
26723 explicit dereference whose designated object is an unconstrained array.
26724 Current algorithm for removing duplicate checks is over-eager in this
26727 * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
26728 null-exclusion value by a warning message
26730 * atree.h, atree.ads, atree.adb: Remove Char_Code field support

26736 * exp_util.adb (Insert_Actions): Replace
26737 N_Formal_Subprogram_Declaration by
26738 N_Formal_{Abstract|Concrete}_Subprogram_Declaration.
26739 Char_Literal_Value field is now a Uint.
26741 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
26742 defined for subprogram renaming declarations. When set, the field
26743 indicates the defining entity of a corresponding formal subprogram
26744 when the renaming corresponds to a formal subprogram association in an
26746 (Set_Corresponding_Formal_Spec): New procedure to return
26747 Corresponding_Formal_Spec field.
26748 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration

26756 associated with a tagged primitive subprogram.
26757 (Expand_Dispatching_Call): Add support for a controlling actual that is
26758 directly a value of type Ada.Tag rather than a tagged object.
26760 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
26761 describing the new layout.
26762 (Dispatch_Table): The expander computes the actual array size, allocates
26763 the Dispatch_Table record accordingly, and generates code that displaces
26764 the base of the record after the Typeinfo_Ptr component. The access to
26765 these components is done by means of local functions.
26766 (Offset_To_Top): New function.
26767 (Typeinfo_Ptr): New function.
26768 (Get_TSD): Modified to access the new position of the TSD.
26769 (Set_TSD): Modified to save the TSD in its new position.
26771 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
26772 case of formal abstract subprograms. Add check and message for -gnat05.
26775 * sem_ch12.adb: Add with and use for Sem_Disp.

26779 N_Formal_Subtype_Declaration (which is now a subtype).
26780 (Analyze_Formal_Subprogram): Add handling for
26781 N_Formal_Abstract_Subprogram, marking the formal as abstract and
26782 dispatching, setting the controlling status of the formal parameters
26783 and result, and issuing an error if there is no controlling type for
26784 the formal subprogram.
26785 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
26786 which is an unclean use of that field, we set the new field
26787 Corresponding_Formal_Spec to make the formal subprogram available to
26788 processing in Analyze_Subprogram_Declaration.
26789 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
26790 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
26791 Constrained, so that it is is does not statically match its anonymous
26794 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
26795 abstract formal subprograms in error check for functions returning
26796 abstract types. Set scope of new designator for
26797 a parameterless subprogram, so that it is available when checking the
26798 body for nested subprograms, before full analysis of said body.
26799 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
26800 subprogram only if inner one comes from source.
26801 (Analyze_Function_Call): If the call is given in object notation, the
26802 analysis of the name rewrites the node and analyzes it with the proper
26803 argument list. After analyzing the name, if the call has been rewritten
26804 and the result type is set, no further analysis is needed.
26805 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
26806 mark in function specification, in a context where the formals are
26807 visible and hide outer homographs.
26809 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
26810 as the tagged type for the cases of abstract formal subprograms and
26811 renamings of those. Clean up spec comments.
26812 (Check_Dispatching_Context): Add error message to indicate "abstract
26813 procedure", covering the case of a call to a formal abstract procedure
26814 that has statically tagged operands.
26815 (Check_Dispatching_Call): Check for the case of an actual given by
26816 a tag-indeterminate function call whose type is an ancestor of the
26817 containing call's associated tagged type. This situation can occur
26818 for inherited primitives with function defaults. In this case we
26819 use the tagged type's tag directly as the controlling argument for
26821 (Expand_Call): Name change on call to Expand_Dispatch_Call.
26823 * sprint.adb (Sprint_Node_Actual): Split
26824 N_Formal_Subprogram_Declaration into two alternatives for the new
26825 cases N_Formal_Abstract_Subprogram_Declaration and
26826 N_Formal_Concrete_Subprogram_Declaration.

26896 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26900 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
26901 on the field if Pragma Component_Alignment (Storage_Unit).
26902 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
26903 side-effects as if it were a constant; also make SAVE_EXPR to protect
26905 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
26907 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
26908 (components_to_record): Test it.

26921 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26923 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
26924 component of an array of arrays in an assignment context, and the
26925 aggregate has component associations that require sliding on
26926 assignment, force reanalysis of the aggregate to generate a temporary
26927 before the assignment.
26928 (Must_Slide): Make global to the package, for use in Gen_Assign.
26930 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26932 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
26933 unchecked union with no inferable discriminants, return a
26934 Raise_Program_Error node, rather than inserting it at the point the
26936 (Expand_Record_Equality, Component_Equality): Handle properly the case
26937 where some subcomponent is an unchecked union whose generated equality
26938 code raises program error.
26940 2005-02-09 Doug Rupp <rupp@adacore.com>

26946 Arnaud Charlet <charlet@adacore.com>
26948 * init.c (__gnat_initialize): Add a new parameter eh which contains the
26949 address of the exception registration. The Win32 version of this
26950 routine calls __gnat_install_SEH_handler() to initialize the SEH
26951 (Structured Exception Handling) handler.
26952 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
26953 SEH (Structured Exception Handling) now.
26954 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
26955 (__gnat_initialize for ppc-vxworks): Adjust comments and the
26956 preprocessor condition protecting the call to the extra eh setup
26957 subprogram, which is only available for the ppc target.
26958 (__gnat_clear_exception_count): replaced reference to
26959 variable taskIdCurrent by call to taskIdSelf(), cleaner.
26961 * seh_init.c: New file.
26963 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
26964 (GNATBIND_OBJS): Idem.
26966 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
26967 routine takes a new parameter (a pointer to the exception registration
26968 for the SEH (Structured Exception Handling) support.
26970 * raise.h: (__gnat_install_SEH_handler): New prototype.
26971 Update copyright notice.
26973 * s-tassta.adb (Task_Wrapper): Declare the exception registration
26974 record and initialize it by calling __gnat_install_SEH_handler.

26984 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
26985 [VMS]: Add translations for g-enblsp.adb.
26987 * s-asthan-vms.adb: Removed.
26988 * s-asthan-vms-alpha.adb: Added.

26999 -shared-libgcc is now used by default on some systems (e.g. linux with
27001 Remove references to Makefile.prolog/generic, no longer used.
27003 2005-02-09 Vincent Celier <celier@adacore.com>
27005 * prj-makr.adb (Process_Directory): Put file name in canonical case
27006 before matching against the patterns.
27007 If gnatname has been invoked as <prefix>-gnatname
27008 then invoke the compiler as <prefix>-gcc, not just "gcc".
27010 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27012 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
27013 with expansion disabled. The actual subtype is needed among other
27014 places when the selected component appears in the context of a loop
27015 bound, and denotes a packed array.
27016 (Operator_Check): Always use the first subtype in the
27017 error message, to avoid the appearance of internal base types.
27018 (Transform_Object_Operation): Copy each actual in full
27019 to the parameter associations of the constructed call, rather than
27020 using the shallow copy mechanism of New_Copy_List. This ensures that
27021 the chaining of named associations is done properly.
27022 (Complete_Object_Operation): Rewrite node, rather than
27023 replacing it, so that we can trace back to the original selected
27026 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
27027 and calls that use object notation, if the called function is not
27028 declared in a withed unit, place the elaboration constraint on the
27029 unit in the context that makes the function accessible.
27030 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
27031 imposes an elaboration constraint between two packages.
27033 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27035 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
27036 views of a private type after handling its private dependents, to
27037 maintain proper stack discipline between entry and exit from the
27040 2005-02-09 Cyrille Comar <comar@adacore.com>
27042 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

27053 recursion warnings when compiled with -gnatdm.
27055 2005-02-09 Robert Dewar <dewar@adacore.com>
27057 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
27058 Slight fix to documentation of -gnaty with no parameters
27060 * xr_tabls.ads: Add ??? comment for missing overall comment
27062 * xsinfo.adb: Make default file name be sinfo.h, since this is what
27063 we now use by default.
27065 * xsnames.adb: Adjust end of file test to look for five space followed
27066 by '#' instead of six spaces. The format of xsnames.adb was modified
27067 in the last update.
27069 * a-numeri.ads: Add reference to AI-388 for greek letter pi
27072 * clean.adb: Minor reformatting.
27074 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
27075 gnatname.adb: Minor reformatting
27076 Add 2005 to copyright output when utility is run
27078 * csets.adb: Eliminate obsolete comment
27080 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
27083 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
27085 2005-02-09 Sergey Rybin <rybin@adacore.com>
27087 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
27088 the difference between compact and incompact layout and add the record
27089 representation clause to the example illustrating different layouts.
27090 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
27091 component clauses").
27093 2005-02-09 Florian Villoing <villoing@adacore.com>
27095 * gnat_ugn.texi: Fix typos.
27096 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
27098 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
27099 in the generated documentation.
27101 2005-02-09 Arnaud Charlet <charlet@adacore.com>
27103 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
27105 Update linker wrapper when linking with non GNU C++.
27107 2005-02-09 Pascal Obry <obry@adacore.com>
27110 Document the procedure to debug the DllMain routine on Windows.
27111 Add note about -funwind-tables and mixed Ada and C/C++ programming in
27113 Document new BIND qualifer /RETURN_CODES=VMS.
27115 2005-02-09 Ben Brosgol <brosgol@adacore.com>
27117 * gnat_ugn.texi: Wordsmithing of "GNAT and Libraries" chapter
27118 Edited gnatmetric chapter

27133 * s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
27134 from the VxWorks kernel) that is needed for getting the active
27135 priority of the different tasks.
27137 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
27138 Use a pragma Elaborate_Body in the spec file instead.
27139 Noticed by code reading.
27141 2005-02-09 Thomas Quinot <quinot@adacore.com>
27143 * exp_util.ads: Minor correction in comment.
27145 2005-02-09 Arnaud Charlet <charlet@adacore.com>
27147 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
27148 since this procedure is now too complex to be worth inlining.
27150 2005-02-09 Richard Henderson <rth@redhat.com>
27152 * utils.c (gnat_define_builtin): Remove.
27153 (gnat_install_builtins): Use build_common_builtin_nodes.

27568 note that it applies to obsolete GNAT features, which was previously
27569 omitted. Second we contrast the behavior with that of the new
27570 Ada 2005 AI-368 restriction No_Obsolescent_Features.

27791 TYPE_SIZE_UNIT of result type if SIZE is not specified.
27792 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
27793 of a bitfield, which we know is useless and causes trouble because of
27794 alignment implications.

27798 (process_attributes): Clear DECL_COMMON again when a section attribute
27800 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or

27803 "no bitfield creation", to be used by make_aligning_type. Don't
27804 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
27805 fields claimed addressable still have to be bitfields. Use
27806 value_factor_p instead of a raw binop construction to check for the
27807 position's alignment.

27814 Ed Schonberg <schonberg@adacore.com>
27816 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
27817 with an implicit dereference as its prefix, use
27818 Insert_Explicit_Dereference instead of merely rewriting the prefix into
27819 an explicit dereference. This ensures that a reference to the original
27820 prefix is generated, if appropriate.
27822 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
27823 dereference is rewritten to an explicit one, generate a reference to
27824 the entity denoted by its prefix using the original prefix node, so

27826 access value, if appropriate.
27828 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
27829 emitting 'assigned but never read' warning on a variable on the basis

27842 This deals with the case where the pragma Import specified
27843 an external name, to be handled by the back end.
27845 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
27846 subprogram which is Imported with convention Intrinsic if an
27847 External_Name argument is specified.
27848 (Process_Import_Or_Interface): Properly diagnose link name argument.
27849 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
27850 with Sem_Ch6.Cannot_Inline.

27874 PolyORB_Support.Build_Stub_Type): New subrograms containing the
27875 PCS-specific part of Add_Stub_Type.

27905 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
27906 and the Has_Pragma_Unreferenced flag for each formal before analyzing
27907 the body, to ensure that warnings are properly emitted for each accept
27908 statement of a given task entry.

27936 (Remove_Next): Same cleanup
27938 2004-12-07 Thomas Quinot <quinot@adacore.com>
27940 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
27941 used to record an implicit dereference as a read operation on its
27942 prefix when operating under -gnatc. Necessary to avoid spurious
27943 'variable assigned but never read' warnings in that mode.
27944 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
27945 is a non-overloaded implicit dereference, call the above subprogram to
27946 ensure proper recording of references.
27948 2004-12-07 Gary Dismukes <dismukes@adacore.com>
27950 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
27951 to be resolved later as part of Analyze_Iteration_Scheme's call to

27998 2004-12-07 Vincent Celier <celier@adacore.com>
28000 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
28001 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
28002 and -eit to -ept. Added qualifier
28003 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
28005 2004-11-27 Andreas Schwab <schwab@suse.de>
28007 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
28009 2004-11-25 Arnaud Charlet <charlet@adacore.com>
28011 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
28012 internal implementation unit GNAT.Sockets.Thin,
28013 as their usage for sockets is non-portable (using the read and write
28014 functions from the system runtime library is fine on UNIX but won't
28015 work under Windows).
28017 * mingw32.h: Update copyright notice.
28019 2004-11-25 Arnaud Charlet <charlet@adacore.com>

28068 (Setup_Exception): Do nothing in the GNAT SJLJ case.
28070 * gigi.h (others_decl, all_others_decl): New decls representing the
28071 new Others_Value and All_Others_Value objects.
28072 (struct attrib): Rename "arg" component as "args", since GCC expects a
28073 list of arguments in there.
28075 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
28076 corresponding objects exported by a-exexpr, instead of hardcoded dummy
28079 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
28080 others_decl and all_others_decl instead of hardcoded dummy addresses
28081 to represent "others" and "all others" choices, which is cleaner and
28082 more flexible with respect to the possible eh pointer encoding policies.
28084 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
28085 (process_attributes): Account for the naming change of the "args"
28086 attribute list entry component.
28088 * decl.c (build_attr_list): Rename into prepend_attributes to allow
28089 cumulating attributes for different entities into a single list.
28090 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
28091 attributes for the current entity and propagate first subtype
28092 attributes to other subtypes.
28093 <E_Procedure>: Attribute arguments are attr->args and not
28094 attr->arg any more.
28095 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
28096 argument provided, as this is what GCC expects. Use NULL_TREE instead

28130 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
28131 is not referenced yet because it will be used by the PolyORB DSA
28133 (Insert_Partition_Check): Remove fossile code.
28134 (First_RCI_Subprogram_Id): Document this constant.
28135 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
28137 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
28138 replaced with calls to Get_Library_Unit_Name_String. Previously there
28139 were several instances of the same code in different locations in the
28140 compiler; this checkin completes the replacement of all of these
28141 instances with calls to a common subprogram.
28142 Minor reformatting.
28144 * sem_dist.adb: Remove comment noting that RPC receiver generation
28145 should be disabled for RACWs that implement RASs.

28171 (Expand_Pragma_Psect_Object): New procedure
28172 These procedures contain the revised and cleaned up processing for
28173 these two pragmas. This processing was formerly in Sem_Prag, but

28175 that the pragmas are properly attached to the tree, and that no
28176 nodes are improperly shared.
28178 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
28179 pragmas to Exp_Prag, which is more appropriate.
28180 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
28181 check for duplicates Remove use of Is_Psected flag, no longer needed.
28182 Use new Make_String_Literal function with string.
28184 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
28185 that are functions return universal values, that have to be converted
28186 to the context type.
28187 Use new Make_String_Literal function with string.
28188 (Get_Stream_Convert_Pragma): New function, replaces the use of
28189 Get_Rep_Pragma, which had to be kludged to work in this case.
28191 * freeze.adb: Use new Has_Rep_Pragma function
28193 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
28194 function with string.
28195 Use new Has_Rep_Pragma function.
28197 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
28200 2004-11-18 Robert Dewar <dewar@adacore.com>
28202 * errout.ads, errout.adb: (First_Sloc): New function
28204 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
28205 check (-gnatyx) instead of being included as a redundant construct
28208 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
28209 Style_Check_Order_Subprograms.
28211 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
28212 stylesw.adb: Add Style_Check_Xtra_Parens
28214 * usage.adb: Add line for -gnatyx (check extra parens)
28216 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
28218 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28219 Robert Dewar <dewar@adacore.com>
28221 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
28222 discriminant of a constrained subtype, analyze the copy of the
28223 corresponding constraint, because in some cases it may be only
28224 partially analyzed.
28225 Removes long-lived ??? comments.
28227 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
28228 handled controlled or secondary-stack expressions within the
28229 iteration_scheme of a loop.
28231 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
28232 bounds that may contain functions calls, to prevent memory leaks when
28233 the bound contains a call to a function that uses the secondary stack.
28234 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
28235 generate temporaries for loop bounds that might contain function calls
28236 that require secondary stack and/or finalization actions.
28238 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
28239 selected component and the selector is overloadable (not just a
28240 function) treat as function call, Analyze_Call will disambiguate if
28242 (Analyze_Selected_Component): Do not generate an actual subtype for the
28243 selected component if expansion is disabled. The actual subtype is only
28244 needed for constraint checks.
28245 (Analyze_Allocator): If restriction No_Streams is set, then do
28246 not permit objects to be declared of a stream type, or of a
28247 composite type containing a stream.
28249 * restrict.ads: Remove the a-stream entry from Unit_Array, since
28250 No_Streams no longer prohibits with'ing this package.
28252 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
28253 discriminants, but the parent base has unknown discriminants, there is
28254 no discriminant constraint to inherit. Such a discrepancy can arise
28255 when the actual for a formal type with unknown discriminants is a
28256 similar private type whose full view has discriminants.
28257 (Analyze_Object_Declaration): If restriction No_Streams is set, then
28258 do not permit objects to be declared of a stream type, or of a
28259 composite type containing a stream.
28261 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28263 * exp_dbug.ads: Update documentation to reflect simpler encoding for
28264 protected operations.
28266 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
28267 generated name, it complicates decoding in gdb and hinders debugging
28268 of protected operations.
28269 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
28270 flag for the protected entry barrier function.
28271 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
28272 flag for the protected entry function.
28274 2004-11-18 Nicolas Setton <setton@adacore.com>
28276 * expect.c: Define __unix__ when __APPLE__ is defined.
28278 * Makefile.in: Inform the value of the variable GMEM_LIB in the
28279 Darwin-specific section.
28281 * lang-specs.h: Change the placement of the %1 marker.
28282 Works around the fact that gcc adds -fPIC by default under Darwin.
28284 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28286 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
28287 type of the object with the packed array type, set the Analyzed flag
28288 on the object if it is an entity or simple indexed component, to avoid
28289 spurious type errors.
28291 2004-11-18 Gary Dismukes <dismukes@adacore.com>
28293 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
28294 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
28295 separate line from the version message.
28297 2004-11-18 Ed Falis <falis@adacore.com>
28299 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
28301 (init_float): Eliminate initialization of floating point status for
28302 AE653. The instructions have no effect for vThreads.
28304 2004-11-18 Vincent Celier <celier@adacore.com>
28306 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
28307 gnatbind is invoked with -shared.
28309 2004-11-18 Jose Ruiz <ruiz@adacore.com>
28311 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
28312 for Detect_Blocking which is redundant with the check done within the
28313 procedure Protected_Single_Entry_Call.
28314 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
28315 Detect_Blocking which is redundant with the check done within the
28316 procedure Protected_Single_Entry_Call.
28318 2004-11-18 Vincent Celier <celier@adacore.com>
28320 * makegpr.adb (Compile): Put the compiling switches (in package
28321 Compiler and on the command line) immediately after "-c", instead of
28322 at the end of the command line invocation of the compiler, when
28323 compiling a non-Ada file.
28324 (Build_Global_Archive): When there is no need to rebuild the archive,
28325 set Global_Archive_Exists, so that the archive is passed to the linker
28328 2004-11-18 Robert Dewar <dewar@adacore.com>
28329 Sergey Rybin <rybin@adacore.com>
28332 Remove extra paren check from list of checks for redundant constructs
28333 Add documentation of new -gnatyx style check (check extra parens)
28334 Remove paragraph about gnatelim debug options.
28336 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
28337 objects rather than forbidding dependencies on the package Ada.Streams.
28339 * sinfo.ads: Add ??? note that we should document pragmas passed to
28342 * g-expect.ads: Fix a few typos in the comments.
28344 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
28346 * misc.c (gnat_handle_option): Use %< and %> for quoting in
28349 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
28351 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
28353 2004-11-07 Andreas Schwab <schwab@suse.de>
28355 * Makefile.in (install-gnatlib): Remove spurious hyphen.
28357 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
28360 * Makefile.in (darwin): Set soext to .dylib.
28362 2004-10-26 Vincent Celier <celier@gnat.com>
28363 Thomas Quinot <quinot@act-europe.fr>
28365 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
28366 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
28367 there is no use of GNAT.Sockets.Constants.
28368 Remove remaining pragma Import for C_Write
28369 Remove C_Read and C_Write from internal implementation unit
28370 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
28371 the read and write functions from the system runtime library is fine
28372 on UNIX but won't work under Windows).
28374 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
28375 (Check_Selector): Use C_Recv instead of C_Read.
28376 Selectors are the GNAT.Sockets abstraction to perform a select()
28377 call on a set of descriptors. To allow abortion of an ongoing
28378 select operation, some data is written to a dedicated socket that
28379 is always monitored.
28380 Under Windows, the write and read library functions cannot operate
28381 on sockets, so we need to use send and recv instead, which is portable
28382 across all supported platforms.
28384 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
28385 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
28386 (using the read and write functions from the system runtime library is
28387 fine on UNIX but won't work under Windows).
28389 2004-10-26 Nicolas Setton <setton@act-europe.fr>
28391 * mlib-tgt-darwin.adb: New file.
28393 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
28394 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
28395 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
28396 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
28399 * Makefile.in: Add support for building shared libraries under Darwin.
28400 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
28401 the low level EH init subprogram to be called from __gnat_initialize.
28403 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
28404 indicates which options to pass to the archive indexer.
28406 * mlib-utl.adb: Add support for calling ranlib with additional
28407 options. This is needed for instance under Mac OS X.
28408 (Ranlib_Options): New global variable, used to store the potential
28409 options to pass to ranlib.
28410 (Ar): Use Ranlib_Options when spawning ranlib.
28411 (Initialize): Set the value of ranlib option.
28413 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
28415 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
28416 instead of 8K, to reflect the real potential needs for stack-checking
28419 2004-10-26 Pascal Obry <obry@gnat.com>
28421 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
28423 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
28424 Windows only the initial thread stack size can be set so it is good to
28425 start we a low stack size.
28426 The OS will adjust the size as needed.
28428 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
28429 Nicolas Setton <setton@act-europe.fr>
28431 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
28432 "__unix__" instead of "unix".
28433 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
28434 sections were just mistakenly ignored. The former is
28435 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
28436 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
28437 of hpux. This prevents an unwanted definition of the symbol
28438 convert_addresses in adaint.o.
28440 2004-10-26 Gary Dismukes <dismukes@gnat.com>
28442 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
28443 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
28445 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28447 * a-filico.ads, a-filico.adb: fix incorrect header.
28449 2004-10-26 Javier Miranda <miranda@gnat.com>
28451 * a-ststio.ads: Fix typo in identifier
28453 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28455 * sem_ch4.adb: Minor reformatting.
28457 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28459 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
28460 enabled, check the result of unary and binary operations when the
28461 expression is the right-hand side of an assignment.
28463 2004-10-26 Vincent Celier <celier@gnat.com>
28465 * clean.adb (Delete): Do not output warnings when in quiet output and
28466 not in verbose mode.
28467 (Force_Deletions): New Boolean flag, defaulted to False
28468 (Delete): Only delete a file if it is writable, and when
28469 Force_Deletions is True.
28470 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
28471 (Usage): Line for new switch -f
28472 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
28475 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
28477 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
28478 JM type only if its size matches that of the wrapper. When a size is
28479 prescribed and the field is not aliased, remove the wrapper of a JM
28480 type only if the size is not greater than that of the packed array.
28481 (gnat_to_gnu_entity): Change the extension of packed array wrappers
28484 2004-10-26 Geert Bosch <bosch@gnat.com>
28486 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
28487 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
28488 (Pred): Implement in terms of Succ.
28490 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28492 * exp_aggr.adb (Safe_Component): An aggregate component that is an
28493 unchecked conversion is safe for in-place use if the expression of the
28494 conversion is safe.
28495 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
28496 be expandable in place even if the aggregate does not come from source.
28497 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
28498 designated object of an allocator in place, rather than building it
28499 first on the stack. The previous scheme forces a full copy of the array,
28500 and may be altogether unsusable if the size of the array is too large
28501 for stack allocation.
28503 2004-10-26 Robert Dewar <dewar@gnat.com>
28505 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
28506 compares if the component is atomic.
28508 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
28509 array assignment if the component type is atomic.
28511 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28512 Eric Botcazou <ebotcazou@act-europe.fr>
28514 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
28515 is aliased and is a by_reference type, do not pass by copy.
28516 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
28517 detect whether the call is in the right side of an assignment or
28518 the expression of an object declaration. Recurse on component
28519 association within aggregates.
28520 Call it in the condition that determines whether the temporary is
28521 necessary for correct stack-checking.
28523 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28525 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
28526 RACW_Type, used in the PolyORB version.
28527 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
28528 version and the GARLIC version.
28530 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
28531 Rename RCI_Info to RCI_Locator for better consistency between the
28532 GARLIC and PolyORB versions of the distributed systems annex.
28533 (DSA_Implementation_Name): This enumeration lists the possible
28534 implementations of the Partition Communication Subsystem for the
28535 Distributed Systems Annex (DSA). The three available implementations
28536 are the dummy stub implementation (No_DSA), and two versions based on
28537 two different distribution runtime libraries: GARLIC and PolyORB. Both
28538 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
28540 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
28543 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
28544 between the GARLIC and PolyORB versions of the distributed systems
28546 Remove RE_Unbounded_Reclaim_Pool since it is unused.
28548 2004-10-26 Gary Dismukes <dismukes@gnat.com>
28550 * gnat1drv.adb: Suppress calling the back end when
28551 Frontend_Layout_On_Target is true.
28553 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28555 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
28556 Set_Read_Only): New subprograms.
28557 These new routines allow the user to set or unset the Owner execute
28558 and Owner write permission flags on a file.
28560 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
28561 GNAT.OS_Lib.Set_Executable instead of rolling our own.
28563 2004-10-26 Matthew Gingell <gingell@gnat.com>
28565 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
28567 2004-10-26 Pascal Obry <obry@gnat.com>
28569 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
28570 memory before the faulting page we properly test the process read
28571 access for this address using appropriate Win32 routine.
28572 (HPUX sections): guard with "__hpux__" instead of "hpux".
28574 2004-10-26 Robert Dewar <dewar@gnat.com>
28576 * lib-xref.adb (Generate_Reference): Don't complain about reference to
28577 entry parameter if pragma Unreferenced set, since we do not properly
28578 handle the case of multiple parameters.
28580 2004-10-26 Vincent Celier <celier@gnat.com>
28582 * prj-env.adb: (Contains_ALI_Files): New Boolean function
28583 (Ada_Objects_Path.Add): For a library project, add to the object path
28584 the library directory only if there is no object directory or if the
28585 library directory contains ALI files.
28586 (Set_Ada_Paths.Add.Recursive_Add): Ditto
28588 2004-10-26 Vincent Celier <celier@gnat.com>
28590 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
28591 extension of library projects.
28593 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
28594 path defaults to ".:<prefix>/lib/gnat".
28595 (Parse): For an extending all project, allow direct import of a project
28596 that is virtually extended.
28598 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
28599 the specified name is directly imported, return its ID. Otherwise, if
28600 an extension of this project is imported, return the ID of the
28603 2004-10-26 Robert Dewar <dewar@gnat.com>
28605 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
28606 (Sub3): New procedure, used by Scaled_Divide
28607 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
28608 correct more than one instance of failure to propagate carries
28610 (Double_Divide): Handle overflow case of largest negative number
28611 divided by minus one.
28613 * s-arit64.ads (Double_Divide): Document that overflow can occur in
28614 the case of a quotient value out of range.
28617 2004-10-26 Robert Dewar <dewar@gnat.com>
28619 * s-bitops.adb (Bit_Eq): Remove redundant check.
28621 * s-bitops.ads: Minor comment updates
28622 Change some occurrences of Address to System.Address
28624 * s-carsi8.ads: Fix minor cut-and-paste error in comments
28626 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28628 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
28629 accessibility check to prefix that is a protected operation.
28631 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28633 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
28634 empty, post message on stub.
28636 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28637 Javier Miranda <miranda@gnat.com>
28639 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
28640 current instance appears within a unit that is directly in the context
28642 Used to determine whether the body of the instance should be analyzed
28643 immediately after its spec, to make its subprogram bodies available
28644 for front-end inlining.
28645 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
28646 constraint is not allowed on the component type (AARM 12.5.3(3))
28648 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28650 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
28651 'Storage_Pool): enhance, document & limit detection of non-sharable
28654 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
28656 * s-pooglo.ads: Add more documentation now that this pool is properly
28659 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28661 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
28662 or protected type with discriminants, do not constrain the
28663 corresponding record type if the subtype declaration has no
28664 discriminant constraints. This can be the case in source code, or in
28665 the subtype declaration created to rename an actual type within an
28668 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28670 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
28671 different kind of stub (possibly wrong name for file), do not check
28673 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
28674 includes call to some function that returns an unconstrained type, do
28677 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28679 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
28680 appear in the code for the main unit. Dependencies among units in the
28681 context of the main unit are established when those other units are
28682 compiled. Otherwise spurious elaboration constraints can generate
28683 incorrect elaboration circularities.
28685 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28686 Ed Schonberg <schonberg@gnat.com>
28688 * sem_util.adb (Is_Aliased_View): Defend against the case where this
28689 subprogram is called with a parameter that is not an object name. This
28690 situation arises for some cases of illegal code, which is diagnosed
28691 later, and in this case it is wrong to call Is_Aliased, as that might
28692 cause a compiler crash.
28693 (Explain_Limited_Type): Refine previous fix to include
28694 inherited components of derived types, to provide complete information.
28696 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
28697 is the prival for a protected object.
28698 It is necessary to mark this entity as a variable, in addition to
28699 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
28700 modified to avoid checking the Aliased flag on entities that are not
28701 objects. (Checking that flag for non-objects is erroneous and could
28702 lead to a compiler crash).
28704 2004-10-26 Robert Dewar <dewar@gnat.com>
28706 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
28707 X_Frac = 0.5, then we know that the number X must be positive.
28708 (Succ): Remove the same redundant test, and also fix the primary test
28709 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
28711 (Decompose): Add fuller comments to spec
28713 2004-10-26 Pascal Obry <obry@gnat.com>
28715 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
28716 validity (process must have read access). Set to 0 in all other cases.
28717 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
28718 violation on Win32.
28719 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
28720 segmentation violation.
28722 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
28724 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
28725 whose type is a constructed subtype of an aliased object with an
28726 unconstrained nominal subtype, convert the actual to the constructed
28727 subtype before taking its address.
28729 2004-10-26 Vincent Celier <celier@gnat.com>
28731 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
28732 (Is_Path_Name_Case_Sensitive): New function
28734 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
28735 (Base_Name, Simple_Name, Current_Directory, Compose,

28739 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28740 Vasiliy Fofanov <fofanov@act-europe.fr>
28741 Vincent Celier <celier@gnat.com>
28743 * gnat_ugn.texi: Generalize "finding memory problems" section into a
28744 "memory management issues" section and document some of the useful
28745 memory pools provided as part of the GNAT library.
28746 Remove "virtual" from declaration of A::method2 in
28747 the simple example of Ada/C++ mixed system.
28748 Library Projects may be virtually extended: their virtual extensions
28749 are not Library Projects.
28750 Added section on extending project hierarchies.
28752 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
28754 * adaint.c (__gnat_get_libraries_from_registry): Cast value
28756 (__gnat_portable_spawn): Remove const.
28758 * mingw32.h (MAXPATHLEN): Check for previous definition.
28760 2004-10-17 Matthias Klose <doko@debian.org>
28762 * gnatvsn.ads: Set gnat library version to 4.0.
28764 2004-10-05 Vincent Celier <celier@gnat.com>

28768 2004-10-04 Laurent Guerby <laurent@guerby.net>
28771 * Makefile.in: Define and use RANLIB_FLAGS.
28773 2004-10-04 Pascal Obry <obry@gnat.com>
28775 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
28776 other x86 platforms).
28778 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
28780 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
28781 in general and triggers stack alignment adjustment for thread entry
28782 points on targets where this is necessary.
28784 2004-10-04 Bernard Banner <banner@gnat.com>
28787 * Makefile.in: Add section for powerpc linux
28788 Add variant i-vxwork-x86.ads
28790 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
28792 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
28794 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
28795 table registration calls when need be. Ensures no reference to the crt
28796 ctors symbol are issued in the SJLJ case, which avoids possible
28797 undefined symbol errors in the case of modules to be statically linked
28800 2004-10-04 Javier Miranda <miranda@gnat.com>
28802 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
28803 in-line the code corresponding to subprogram Analyze_Actuals. In
28804 addition, analyze the actuals only in case of subprogram call.
28806 2004-10-04 Ed Falis <falis@gnat.com>
28808 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size

28813 in the documentation.
28815 2004-10-04 Robert Dewar <dewar@gnat.com>
28817 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
28819 (Analyze_Block_Statement): Add circuitry to detect following dead code
28820 (Check_Unreachable_Code): Handle case of block exit
28822 2004-10-04 Robert Dewar <dewar@gnat.com>
28824 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
28825 (XMatchD): Avoid warning for Logic_Error call
28827 2004-10-04 Robert Dewar <dewar@gnat.com>
28829 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
28830 consider expressions buried within a procedure actual to be an actual.
28831 This caused some blowups with uses of packed slices within a procedure
28834 2004-10-04 Robert Dewar <dewar@gnat.com>
28836 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
28837 longer need to be initialized to zero.
28838 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
28839 initialized to zero.
28841 * checks.adb (Expr_Known_Valid): Packed arrays are now always
28842 considered valid, even if the representation is modular. That's correct
28843 now that we no longer initialize packed modular arrays to zero.
28845 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
28846 suffixes. These are now documented as the only cases in which the
28847 debugger ignores outer records.
28848 Previously, the spec allowed arbitrary suffixes for this purpose.
28849 Change name of LJM to JM for packed array pad records
28850 Create separate section on packed array handling, and add a whole new
28851 set of comments to this section describing the situation with packed
28852 modular types and justification requirements depending on endianness.
28854 2004-10-04 Robert Dewar <dewar@gnat.com>
28856 * a-except.adb: Add a comment for last change
28858 * einfo.ads: Minor spelling correction in comment
28860 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
28862 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
28865 * sem_util.ads: Minor comment update
28867 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28869 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
28870 Inline_Always when in Configurable_Run_Time mode.
28872 * sem_prag.adb (Process_Convention): If entity is an inherited
28873 subprogram, apply convention to parent subprogram if in same scope.
28874 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
28875 when in Configurable_Run_Time mode.
28877 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28879 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
28880 class_wide type after component list has been inherited.
28882 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28884 * sem_ch12.adb (Check_Generic_Actuals): New predicate
28885 Denotes_Previous_Actual, to handle properly the case of a private
28886 actual that is also the component type of a subsequent array actual.
28887 The visibility status of the first actual is not affected when the
28888 second is installed.
28889 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
28890 make fully recursive the treatment of formals of packages declared
28892 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
28893 the above on exit from an instantiation.
28894 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
28895 current instantiation which is now complete.
28896 (Analyze_Package_Instantiation): No instantiated body is needed if the
28897 main unit is generic. Efficient, and avoid anomalies when a instance
28898 appears in a package accessed through rtsfind.
28900 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28902 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
28903 do not generate a declaration for a temporary if the call is part of a
28904 library-level instantiation.
28906 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28908 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
28909 searching for a limited component to flag.
28911 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
28912 expansion of Input, to account for the fact that the implicit call
28913 generated by the attribute reference must freeze the user-defined
28914 stream subprogram. This is only relevant to 'Input, because it can
28915 appear in an object declaration, prior to the body of the subprogram.
28917 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
28918 expansion can proceed and further errors uncovered.
28919 (Minor clean up): Fix cases of using | instead of \ for continuation
28922 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28924 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
28926 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
28927 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
28928 Use gcc_assert and gcc_unreachable.
28930 * decl.c (gnat_to_gnu_entity, case object): Check and process a
28931 specified alignment before validating size.
28932 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
28933 stripped-down declaration for the type of the inner field when making
28936 * utils.c (finish_record_type): Do not compute the size in units
28937 incrementally. Instead compute it once for the rep clause case.
28938 Use gcc_assert and gcc_unreachable.
28940 2004-10-04 Vincent Celier <celier@gnat.com>
28942 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
28944 (Is_Valid_Path_Name): Take '/' as a directory separator.
28946 2004-10-04 Vincent Celier <celier@gnat.com>
28948 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
28949 (Extended_Project) only if Extended_Project is defined, to avoid
28951 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
28953 (Parse_Single_Project): Ditto.
28955 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
28956 Add_To_Project_Path for virtual projects.
28958 2004-10-04 Vincent Celier <celier@gnat.com>
28960 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

28963 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
28964 parameter Options_2.
28966 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
28967 Build_Dynamic_Library with an empty Options_2.
28969 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
28972 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
28973 directory separator, if any.
28974 (Gprmake): Do not allow mains on the command line for library projects.
28975 Do not attempt to link when the project is a library project.
28976 (Library_Opts): New table to store Library_Options.
28977 (Build_Library): If Library_Options is specified, pass these options
28978 when building a shared library.
28980 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
28982 * s-tposen.adb (Service_Entry): The object must be always unlocked at
28983 the end of this procedure now that the unlock operation was inserted
28986 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
28988 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
28989 corresponding to the Preallocated_Stacks flags in System.
28990 (Get_Target_Parameters): Including the processing for
28991 Preallocated_Stacks.
28993 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,

28997 system-vxworks-sparcv9.ads, system-vxworks-xscale.ads,
28998 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
28999 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
29000 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
29001 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
29002 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
29003 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
29004 used to signal whether the compiler creates the required stacks and
29005 descriptors for the different tasks (when True) or it is done by the
29006 underlying operating system at run time (when False).
29007 It is initially set to False in all targets.
29009 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
29010 if it is supported by the target.
29011 (Make_Task_Create_Call): Pass the stack address if it has been
29012 previously created. Otherwise pass a Null_Address.
29014 * snames.adb: Add _stack.
29016 * snames.ads: Add Name_uStack. Required to allow the expander to
29017 statically allocated task stacks.
29019 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
29020 Stack_Address argument.
29021 Check that its value is equal to Null_Address because this target does
29022 not support the static stack allocation.
29024 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29026 * usage.adb: Change "pragma inline" to "pragma Inline" in information
29029 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29031 * exp_dist.adb: Split declaration of asynchronous flag out of
29032 Add_RACW_Read_Attribute.
29033 Minor reformatting for better alignment with PolyORB version.
29034 Store the entity for the asynchronous flag of an RACW, rather than the
29035 expression, in the asynchronous flags table. This will allow this flag
29036 to be used in other subprograms beside Add_RACW_Read_Attribute.
29038 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29040 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
29041 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
29042 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
29043 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
29044 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
29045 sockets constant MSG_NOSIGNAL (Linux-specific).
29046 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
29047 all Send operations.
29048 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
29049 from trigerring SIGPIPE.
29050 Rename components to avoid clash with Ada 2005 possible reserved
29052 (Check_Selector): When the select system call returns with an error
29053 condition, propagate Socket_Error to the caller.
29055 2004-10-01 Jan Hubicka <jh@suse.cz>
29057 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
29059 2004-09-23 Robert Dewar <dewar@gnat.com>
29062 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
29063 instead do this at freeze time (we won't do it if there is an address
29065 Change "pragma inline" to "pragma Inline" in information and error
29067 Minor reformatting.
29069 * freeze.adb (Check_Address_Clause): Remove previous change, not the
29070 right way of doing things after all.
29071 (Freeze_Entity): For object, set Is_Public for imported entities
29072 unless there is an address clause present.
29074 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
29076 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
29077 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
29078 ensures proper handling of types with rep clauses, which might have
29079 their TYPE_SIZE set already.
29081 2004-09-21 Robert Dewar <dewar@gnat.com>
29083 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
29084 packed array types in both little- and big-endian cases. This change
29085 ensures that we no longer count on the unused bits being initialized
29086 for such types (and in particular ensures that equality testing will
29087 only read the relevant bits).
29088 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29089 These changes mean that we no longer need to initialize small packed
29091 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
29092 optimization to an LJM field as to its parent field.
29094 * ada-tree.h, trans.c, utils.c, utils2.c:
29095 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29097 2004-09-20 Jan Hubicka <jh@suse.cz>
29099 * utils.c (gnat_finalize): Remove.
29100 (end_subprog_body): Directly call cgraph_finalize_function;
29101 do not lower the nested functions.
29103 2004-09-20 Robert Dewar <dewar@gnat.com>
29106 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
29107 if an address clause is present, since that means that the Import
29110 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
29112 * 5tsystem.ads: Removed, no longer used.
29114 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
29115 Zack Weinberg <zack@codesourcery.com>
29117 * ada-tree.def: Use tree_code_class enumeration constants
29118 instead of code letters.
29119 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
29120 Update for new tree-class enumeration constants.
29122 2004-09-17 Vincent Celier <celier@gnat.com>
29124 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
29125 capabilities of the general project manager.
29127 2004-09-09 Vincent Celier <celier@gnat.com>
29129 * a-direct.ads: Add pragma Ada_05
29130 (Directory_Entry_Type): Give default value to component Kind to avoid
29131 not initialized warnings.
29133 * a-direct.adb (Current_Directory): Remove directory separator at the
29135 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
29136 an existing directory.
29137 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
29138 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
29139 Convert the result to File_Size.
29141 * prj.ads: (Project_Error): New exception
29143 * prj-attr.adb: Except in procedure Initialize, Fail comes from
29144 Prj.Com, not from Osint.
29145 (Attrs, Package_Attributes): Tables moved to private part of spec
29146 (Add_Attribute, Add_Unknown_Package): Moved to new child package
29148 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
29149 Prj.Project_Error after call to Fail.
29150 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
29151 Fail. Check that package name is not already in use.
29153 * prj-attr.ads: Comment updates to indicate that all subprograms may be
29154 used by tools, not only by the project manager, and to indicate that
29155 exception Prj.Prj_Error may be raised in case of problem.
29156 (Add_Unknown_Package, Add_Attribute): Moved to new child package
29158 (Attrs, Package_Attributes): Table instantiations moved from the body to
29159 the private part to be accessible from Prj.Attr.PM body.
29161 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
29162 from new package Prj.Attr.PM.
29163 (Parse_Attribute_Declaration): Call Add_Attribute from new package
29166 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
29168 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
29169 instead of Elaboration_Checks).
29171 * a-calend.adb: Minor reformatting
29173 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29175 * gigi.h (maybe_pad_type): New declaration.
29176 (create_subprog_type): New arg RETURNS_BY_TARGET_PTR.
29178 * ada-tree.h: (TYPE_RETURNS_BY_TARGET_PTR_P): New macro.
29180 * cuintp.c: Convert to use buildN.
29182 * decl.c (maybe_pad_type): No longer static.
29183 (gnat_to_gnu_entity, case E_Function): Handle case of returning by
29185 Convert to use buildN.
29187 * trans.c (call_to_gnu): Add arg GNU_TARGET; support
29188 TYPE_RETURNS_BY_TARGET_PTR_P. All callers changed.
29189 (gnat_to_gnu, case N_Assignment_Statement): Call call_to_gnu if call on
29191 (gnat_to_gnu, case N_Return): Handle TYPE_RETURN_BY_TARGET_PTR_P.

29219 raise Program_Error if called from a protected operation.
29221 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
29222 the protected action nesting level.
29223 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
29224 protected action nesting level.
29225 (Unlock): When pragma Detect_Blocking is active decrease the protected
29226 action nesting level.
29228 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
29229 Protected_Action_Nesting.
29231 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
29232 Common_ATCB record. It contains the dynamic level of protected action
29233 nesting for each task. It is needed for checking whether potentially
29234 blocking operations are called from protected operations.
29235 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
29236 Detect_Blocking is active or not in the partition.
29238 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

29270 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
29271 insertion of the statement raising Program_Error. The run time
29272 contains the required machinery for handling that.
29274 * sem_util.ads: Change comment associated to procedure
29275 Check_Potentially_Blocking_Operation.
29276 This procedure does not insert a call for raising the exception because
29277 that is currently done by the run time.
29279 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
29281 * init.c: Add the global variable __gl_detect_blocking that indicates
29282 whether pragma Detect_Blocking is active (1) or not (0). Needed for
29283 making the pragma available at run time.
29284 (__gnat_set_globals): Pass and update the detect_blocking parameter.
29286 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
29287 pragma Detect_Blocking is active.
29289 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
29291 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
29292 DB is found in the ali file. Any unit compiled with pragma
29293 Detect_Blocking active forces its effect in the whole partition.
29295 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
29296 Detect_Blocking is active and delay is called from a protected
29299 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
29300 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
29301 Detect_Blocking is active (0 otherwise).
29302 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
29303 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
29306 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
29308 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
29309 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
29312 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
29313 (Register_Receiving_Stub): Add Subp_Info formal parameter.
29314 Update API in placeholder implemetation of s-parint to reflect changes
29315 in distribution runtime library.
29317 * sem_ch3.adb (Expand_Derived_Record): Rename to
29318 Expand_Record_Extension.
29320 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
29321 primitive operations of potentially distributed object types that have
29322 non-controlling anonymous access formals.
29324 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
29326 New implementation of expansion for remote access-to-subprogram types,
29327 based on the RACW infrastructure.
29328 This version of sem_dist is compatible with PolyORB/DSA as well as
29331 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
29332 Asynchrronous that applies to a remote access-to-subprogram type, mark
29333 the underlying RACW type as asynchronous.
29335 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
29336 __gnat_using_gnu_linker to 1.
29338 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
29339 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

29345 * exp_ch3.adb (Expand_Derived_Record): Rename to
29346 Expand_Record_Extension.
29347 (Build_Record_Init_Proc.Build_Assignment): The default expression in
29348 a component declaration must remain attached at that point in the
29349 tree so New_Copy_Tree copies it if the enclosing record type is derived.
29350 It is therefore necessary to take a copy of the expression when building
29351 the corresponding assignment statement in the init proc.
29352 As a side effect, in the case of a derived record type, we now see the
29353 original expression, without any rewriting that could have occurred
29354 during expansion of the ancestor type's init proc, and we do not need
29355 to go back to Original_Node.
29357 * exp_ch3.ads (Expand_Derived_Record): Rename to
29358 Expand_Record_Extension.
29360 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

29363 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
29364 New subprograms. Used to create a proxy tagged object for a remote
29365 subprogram. The proxy object is used as the designated object
29366 for RAS values on the same partition (unless All_Calls_Remote applies).
29367 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
29368 System.Partition_Interface.Get_Unique_Remote_Pointer.
29369 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
29370 Renamed from Add_RAS_*_Attribute.
29371 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
29373 New implementation of expansion for remote access-to-subprogram types,
29374 based on the RACW infrastructure.
29376 * exp_dist.ads (Copy_Specification): Update comment to note that this
29377 function can copy the specification from either a subprogram
29378 specification or an access-to-subprogram type definition.
29380 2004-09-09 Ed Schonberg <schonberg@gnat.com>
29382 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
29383 in an instance, between an explicit subprogram an one inherited from a
29384 type derived from an actual.
29386 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
29387 add a polling call if the subprogram is to be inlined by the back-end,
29388 to avoid repeated calls with multiple inlinings.
29390 * checks.adb (Apply_Alignment_Check): If the expression in the address
29391 clause is a call whose name is not a static entity (e.g. a dispatching
29392 call), treat as dynamic.
29394 2004-09-09 Robert Dewar <dewar@gnat.com>
29396 * g-trasym.ads: Minor reformatting
29398 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

29407 2004-09-09 Pascal Obry <obry@gnat.com>
29409 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
29410 enable map file generation. Add the right option to generate the map
29411 file if Map_File is set to True.
29413 * gnatdll.adb (Gen_Map_File): New variable.
29414 (Syntax): Add info about new -m (Map_File) option.

29437 * opt.ads: Add Ada_Version_Runtime constant used to decide which
29438 version of the language is used to compile the run time.
29440 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
29442 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
29443 of variable length temporaries for function return now that the
29444 back-end and gigi support it.

29495 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
29496 packed indexed component where array is an IN OUT formal. This
29497 generated garbage code previously.
29499 * gnat_ugn.texi: Document -fverbose-asm
29501 * gnat-style.texi: Minor updates (note that boolean constants and
29502 variables are joined with AND/OR rather than short circuit forms).
29504 2004-09-01 Ed Schonberg <schonberg@gnat.com>
29506 * exp_util.adb (Safe_Unchecked_Type_Conversion): Conversion is safe if
29507 it is an upward conversion of an untagged type with no representation

29515 * checks.adb (Apply_Access_Checks): Do not generate checks when
29516 expander is not active (but check for unset reference to prefix of
29519 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
29520 pragma Debug as an if statement with a constant condition, for
29521 consistent treatment of entity references contained within the
29522 enclosed procedure call.
29524 2004-09-01 Vincent Celier <celier@gnat.com>
29526 * bindgen.adb: (Set_EA_Last): New procedure
29527 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
29529 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing

29551 2004-09-01 Pascal Obry <obry@gnat.com>
29553 * gprcmd.adb (Extend): Do not output trailing directory separator. This
29554 is not needed and it confuses Windows GNU/make which does not report
29555 directory terminated by a slash as a directory.
29556 (gprcmd): Idem for "pwd" internal command.
29558 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
29559 target names rewrite to fix regressions with recent version of

29611 2004-08-16 Pascal Obry <obry@gnat.com>
29613 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
29614 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
29615 option and not mdll anymore. Update comment.
29617 2004-08-16 Pascal Obry <obry@gnat.com>
29619 * bld.adb (Put_Include_Project): Properly handle directory separators
29622 2004-08-16 Ed Schonberg <schonberg@gnat.com>

29635 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
29637 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
29638 for a global aliased object with a variable size and an unconstrained
29639 nominal subtype, pretend there is no initializer if the one we have is
29640 incomplete, and avoid referencing an inexistant component in there. The
29641 part we have will be rebuilt anyway and the reference may confuse
29642 further operations.
29644 2004-08-13 Thomas Quinot <quinot@act-europe.fr>
29646 * einfo.ads: Minor reformatting
29648 * lib-writ.adb (Output_Main_Program_Line): Do not set parameter

29662 2004-08-13 Ed Schonberg <schonberg@gnat.com>
29664 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
29665 unit, this is an attempt to inline a construct that is not available in
29666 the current restricted mode, so abort rather than trying to continue.
29668 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
29669 discriminants that rename those of the parent, recover names of
29670 original discriminants for the constraint on the full view of the
29672 (Complete_Private_Subtype): Do not create a subtype declaration if the
29673 subtype is an itype.
29675 * gnat_rm.texi: Added section on implementation of discriminated
29676 records with default values for discriminants.
29678 2004-08-13 Ed Schonberg <schonberg@gnat.com>

32289 * trans.c (gnat_stabilize_reference_1): Remove case 'b'.
32291 2004-05-13 Diego Novillo <dnovillo@redhat.com>
32293 Merge from tree-ssa-20020619-branch.
32295 * config-lang.in (boot_language, build_by_default): Set
32297 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
32298 (max_size): Add static chain op for call_expr.
32300 2004-05-12 Richard Sandiford <rsandifo@redhat.com>
32303 * 5gmastop.adb (Roff): Choose between '4' and '0', not '4' and ' '.
32305 2004-05-11 Roger Sayle <roger@eyesopen.com>
32307 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a

32319 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
32320 Fixes undefined symbols in IA64 gnatlib.
32322 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
32324 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype

32332 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
32333 Analyze on the library unit node after generation of distribution stub
32334 constructs. The call was a no-op because Unit_Node has already been
32335 Analyzed, and the tree fragments for the distribution stubs are
32336 analyzed as they are inserted in Exp_Dist.
32337 Update comment regarding to distribution stubs to reflect that we
32338 do not generate stub in separate files anymore.

32356 has been rewritten as an explicit dereference, retrieve type of
32357 original node to check for possibly unconstrained record type.
32359 2004-05-10 Ed Schonberg <schonberg@gnat.com>
32361 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
32362 overriding, use the operation of the parent unconditionally.
32364 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
32365 operation when either operand is a literal, to avoid further
32368 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
32369 overridden by a previous explicit declaration, mark the previous entity
32372 * sem_disp.adb (Check_Dispatching_Operation): New predicate
32373 Is_Visibly_Controlled, to determine whether a declaration of a
32374 primitive control operation for a derived type overrides an inherited
32375 one. Add warning if the explicit declaration does not override.
32377 2004-05-10 Vincent Celier <celier@gnat.com>
32379 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
32380 some cases when the sources are no longer present.
32382 * make.adb (Collect_Arguments): Fail if an external source, not part
32383 of any project need to be compiled, when switch -x has not been
32386 * makeusg.adb: Document new switch -x
32388 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
32389 defaulted to False.

32393 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
32394 gnatmake switch -x.
32396 * gnat_ugn.texi: Document new gnatmake switch -x
32398 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
32400 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
32402 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
32403 (process_attributes): Likewise.
32405 2004-05-10 Joel Brobecker <brobecker@gnat.com>
32407 * s-inmaop.ads: Fix spelling mistake in one of the comments.
32409 2004-05-10 Robert Dewar <dewar@gnat.com>
32411 * gnat_ugn.texi: Document that for config pragma files, the maximum
32412 line length is always 32767.
32414 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
32415 literals is now allowed.
32417 * gnat-style.texi: Remove statement about splitting long lines before
32418 an operator rather than after, since we do not follow this rule at all.
32419 Clarify rule (really lack of rule) for spaces around exponentiation
32421 * sem_elim.adb: Allow concatenation of string literals as well as a
32422 single string literal for pragma arguments.
32424 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
32426 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
32427 written for append case.
32429 * frontend.adb: Changes to avoid checking max line length in config
32432 * g-os_lib.ads: Minor reformatting
32434 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
32435 wrong in any case. Instead use standard value. Noticed during code
32438 * opt.ads (Max_Line_Length): New field, used to implement removal of
32439 limitation on length of lines when scanning config pragma files.
32441 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
32442 makeutl.ads, makeutl.adb: Minor reformatting

33581 2004-04-05 Vincent Celier <celier@gnat.com>
33584 * make.adb (Scan_Make_Arg): Pass any -fxxx switches to gnatlink, not
33585 just to the compiler.
33587 2004-04-05 Robert Dewar <dewar@gnat.com>

33614 (Leading_Part): Still perform truncation to machine number if the
33615 specified radix_digits is greater or equal to machine_mantissa.
33617 2004-04-05 Javier Miranda <miranda@gnat.com>
33619 * par-ch3.adb: Complete documentation of previous change
33620 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

33625 * par-ch6.adb: Complete documentation of previous change.
33627 * sinfo.ads: Fix typo in commment.
33629 2004-04-05 Ed Schonberg <schonberg@gnat.com>
33631 * sem_ch3.adb (Inherit_Components): If derived type is private and has
33632 stored discriminants, use its discriminants to constrain parent type,
33633 as is done for non-private derived record types.
33635 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
33636 Ada 2005 AI-310: an abstract non-dispatching operation is not a
33637 candidate interpretation in an overloaded call.
33639 * tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
33640 expression is Null and target type is not an access type (e.g. a

33645 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
33646 statement whose right-hand side is an inlined call, save a copy of the
33647 original assignment subtree to preserve enough consistency for
33648 Analyze_Assignment to proceed.
33650 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
33651 complete assignment subtree which is now unnecessary, as the expansion
33652 of inlined call has been improved to preserve a consistent assignment
33653 tree. Note_Possible_Modification must be called only
33654 after checks have been applied, or else unnecessary checks will
33657 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
33658 of explicit dereferences that do not Come_From_Source:
33659 - be selective on cases where we must go back to the dereferenced
33660 pointer (an assignment to an implicit dereference must not be
33661 recorded as modifying the pointer);
33662 - do not rely on Original_Node being present (Analyze_Assignment
33663 calls Note_Possible_Modification on a copied tree).
33665 * sem_warn.adb (Check_References): When an unset reference to a pointer
33666 that is never assigned is encountered, prefer '<pointer> may be null'
33667 warning over '<pointer> is never assigned a value'.

33677 libexc. We currently don't reference anything in this library and
33678 linking it in triggers linker warnings we don't want to see.
33680 * init.c: Update comments.

33721 2004-04-01 Robert Dewar <dewar@gnat.com>
33723 * checks.adb: Minor reformatting throughout
33724 Note that prev checkin added RM reference to alignment warning
33726 2004-04-01 Ed Schonberg <schonberg@gnat.com>

33729 non-static when building aggregate for bit-packed array.
33731 * exp_ch4.adb (Expand_N_Slice): If a packed slice is an actual of a
33732 function call that is itself the actual in a procedure call, build

33736 a string literal, create a temporary for it, constant folding only
33737 handles scalars here.
33739 2004-04-01 Vincent Celier <celier@gnat.com>

33920 allows to configure paths for an executable name (gnatmake) different
33921 from the current one (gnatdist).
33923 2004-03-29 Ed Schonberg <schonberg@gnat.com>
33925 * exp_ch6.adb (Expand_Call): A call to a function declared in the
33926 current unit cannot be inlined if it appears in the body of a withed
33927 unit, to avoid order of elaboration problems in gigi.
33929 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
33930 information for protected (wrapper) operation as well, to simplify gdb
33933 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

33972 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
33973 attribute reference does not denote a subtype, it can be any
33974 expression that has a classwide type, potentially after an implicit
33975 dereference. In particular, the prefix can be a view conversion for
33976 a classwide type (for which Is_Object_Reference holds), but it can
33977 also be a value conversion for an access-to-classwide type. In the
33978 latter case, there is an implicit dereference, and the original node
33979 for the prefix does not verify Is_Object_Reference.
33981 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
33982 conversion of a discriminant-dependent component of a mutable object

34006 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
34007 value expressions to ensure that calls within a component definition
34008 will be checked (since those are evaluated during the record type's

34060 declaration for a child subprogram body that acts as a spec, indicate
34061 that the entity in the declaration needs debugging information.

34064 full view if the subtype is created for a constrained record component;
34065 gigi has enough information to construct the record, and there is no
34066 place in the tree for the declaration.
34068 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
34069 serial number for the dummy body that is built for analysis, to avoid

34109 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
34111 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
34112 as regular exception objects and not as mere integers representing the
34113 condition code. The latter approach required some dynamics to mask off
34114 severity bits, which did not fit well into the GCC table based model.
34115 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
34116 exception data objects. We don't it and it would conflict with the other
34117 external symbol we have to generate for such exceptions.
34119 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
34120 the special code for VMS exceptions, since these are now represented
34121 as regular exceptions objects.

34161 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
34163 * init.c [VxWorks]: Do not fix the stack size for the environment task.
34164 When needed (stack checking) the stack size is retrieved
34165 from the VxWorks kernel.
34167 * Makefile.in: Flag -nostdinc is required when building the run time
34168 for avoiding looking for files in the base compiler.
34169 Add the VxWorks specific version of the package body for
34170 System.Stack_checking.Operations (5zstchop.adb).
34172 * Make-lang.in: Add the object file for
34173 System.Stack_Checking.Operations.

34198 the procedures Add_To_Path_File.
34199 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
34200 making sure that each directory is present only once and, for object
34201 dirs, when a directory already present is added, the duplicate is
34202 removed and the directory is always put as the last in the table.
34203 Write the path files at the end of these accumulations.
34205 * prj-nmsc.adb (Record_Source): Add source file name in hash table
34206 Files_Htable for all sources.

34221 * scn.adb (Determine_License): Take into account a degenerated case
34222 when the source contains only comments.
34224 2004-03-18 Ed Schonberg <schonberg@gnat.com>
34226 * sem_warn.adb (Check_References): For a warning on a selected
34227 component that does not come from source, locate an uninitialized
34228 component of the record type to produce a more precise error message.
34230 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
34232 * 3zsoccon.ads: Fix multicast options.
34234 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
34237 2004-03-15 Robert Dewar <dewar@gnat.com>

34254 * a-ngcoty.adb (Modulus): In alternate formula for large real or
34255 imaginary parts, use Double precision throughout.
34257 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
34258 we want to be able to compile run-time with -gnata for testing, but
34259 this may also be instantiated in user code that is compiled with -gnata.
34261 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
34263 * s-stalib.ads (Exception_Code): New type, to represent Import/Export

34278 occurrence matches some handler choice specification. Extracted out of
34279 get_action_description_for, and expanded to take care of the VMS
34281 (get_action_description_for): Use is_handled_by instead of an explicit
34282 complex condition to decide if the current choice at hand catches the
34283 propagated occurrence.

34287 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
34288 System.Standard_Library.Exception_Code, to allow references from the
34289 pragma import/export expander.
34291 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
34292 New accessors to allow easy access to GNAT exception data
34294 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
34295 redundant Handled_By_Others component, helper for the personality
34296 routine which will now be able to call the appropriate exception data
34299 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
34300 component of Standard_Exception_Type to be the closest possible to
34301 Exception_Code in System.Standard_Library, that we cannot get at this
34302 point. Expand a ??? comment to notify that this type node should
34303 probably be rewritten later on.
34305 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
34306 registration call to include a pointer to the exception object in the
34309 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

34318 longer needed now that it is in the spec of
34319 System.Tasking.Task_Attributes.

34323 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
34325 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
34327 * make.adb (Gnatmake): Do not check the executable suffix; it is being
34328 taken care of in Scan_Make_Arg.
34329 (Scan_Make_Arg): Add the executable suffix only if the argument
34330 following -o, in canonical case, does not end with the executable
34331 suffix. When in verbose mode and executable file name does not end
34332 with executable suffix, output the executable name, in canonical case.
34334 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
34335 to avoid warnings when instantiating Ada.Task_Attributes.

34351 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
34352 tagged type is inherited, and the parent operation is not frozen yet,
34353 force generation of a freeze node for the inherited operation, so the
34354 corresponding dispatch entry is properly initialized.
34355 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
34356 when looking for user-defined equality operation.

34359 boolean when locating primitive equality of tagged component.
34361 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

34370 after object declaration, skipping over code that may have been
34371 generated for validity checks.
34373 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown

34375 any, to check legality.
34377 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
34378 component if type has unknown discriminants.
34379 (Analyze_Private_Extension_Declaration): Discriminant constraint is

34383 for end label when present.
34385 * s-fileio.adb (Open): When called with a C_Stream, use given name for
34386 temporary file, rather than an empty string.
34388 2004-03-15 Ed Falis <falis@gnat.com>

34412 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
34413 Insert_Dereference_Action when rewriting an implicit dereference into
34414 an explicit one, this will be taken care of during expansion of the
34415 explicit dereference.
34416 (Expand_N_Slice): Same. Always do the rewriting, even for the case
34417 of non-packed slices, since the dereference action generated by
34418 expansion of the explicit dereference is needed in any case.
34419 (Expand_N_Selected_Component): When rewriting an implicit dereference,
34420 analyze and resolve the rewritten explicit dereference so it is seen
34422 (Insert_Dereference_Action): This procedure is now called only for the
34423 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
34424 dereferences that do not come from source (including explicit
34425 dereferences resulting from rewriting implicit ones), but do not
34426 recursively insert a check for the dereference nodes contained within
34428 (Insert_Dereference_Action): Clarify and correct comment.

35305 checks for bitfield creation are triggered.
35306 (finish_record_type): During last pass over the fields, clear
35307 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

35706 Minor changes to avoid -gnatwa warnings
35707 Correct some instances of using OR instead of OR ELSE (noted while
35708 doing reformatting)
35710 * sprint.adb: Minor updates to avoid -gnatwa warnings
35712 * s-secsta.ads, s-secsta.adb:
35713 (SS_Get_Max): New function to obtain high water mark for ss stack
35714 Default_Secondary_Stack is not a constant since it may be modified by
35715 the binder generated main program if the -D switch is used.
35717 * switch-b.adb: New -Dnnn switch for binder
35720 Make -gnatg imply all warnings currently in -gnatwa
35722 * vms_conv.adb: Minor reformatting

35747 Minor reformatting and code clean ups.
35748 Minor changes to prevent -gnatwa warnings
35750 * ali.adb: Minor reformatting and cleanup of code
35751 Acquire new SS indication of secondary stack use from ali files
35753 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
35754 (since now we expect this to be done for imported functions)
35756 * bindgen.adb: Generate call to modify default secondary stack size if
35759 * bindusg.adb: Add line for new -D switch
35761 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
35762 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
35763 Add circuitry for both records and arrays to avoid gigi
35764 processing if the type involved has non-bit-aligned components
35766 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
35767 N_String_Literal node always references an E_String_Literal_Subtype
35768 entity. This may not be true in the future.
35769 (Possible_Bit_Aligned_Component): Move processing of
35770 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
35772 * exp_ch6.adb (Expand_Thread_Body): Pick up
35773 Default_Secondary_Stack_Size as variable so that we get value modified
35774 by possible -Dnnn binder parameter.
35776 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
35777 (Type_May_Have_Bit_Aligned_Components): New function.
35779 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.
35780 (Type_May_Have_Bit_Aligned_Components): New function.

35787 importing constant atomic/volatile objects.
35788 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
35789 unless explicit Pure_Function pragma given, to avoid insidious bug of
35790 call to non-pure imported function getting eliminated.
35792 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
35793 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,

35808 New switch Sec_Stack_Used (GNAT, GNATBIND)
35809 Make Default_Secondary_Stack_Size a variable instead of a constant,
35810 so that it can be modified by the new -Dnnn bind switch.
35812 * rtsfind.adb (Load_Fail): Give full error message in configurable
35813 run-time mode if all_errors mode is set. This was not done in the case
35814 of a file not found, which was an oversight.
35815 Note if secondary stack unit is used by compiler.
35817 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
35818 ineffective elaborate all pragmas on non-visible packages (this
35819 happened when a renamed subprogram was called). Now the elaborate all
35820 always goes on the package containing the renaming rather than the one
35821 containing the renamed subprogram.
35823 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
35824 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
35826 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
35827 has an Etype that references an E_String_Literal.
35828 (Eval_String_Literal): Avoid assumption that N_String_Literal node
35829 always references an E_String_Literal_Subtype entity. This may not
35830 be true in the future.
35832 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
35835 * sem_res.adb (Resolve): Specialize msg for function name used in proc
35838 2004-01-05 Ed Falis <falis@gnat.com>
35840 * g-debuti.adb: Replaced direct boolean operator with short-circuit

35845 * bld.adb: Minor comment updates
35846 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
35849 * make.adb (Gnatmake): Special process for files to compile/check when
35850 -B is specified. Fail when there are only foreign mains in attribute
35851 Main of the project file and -B is not specified. Do not skip bind/link
35852 steps when -B is specified.
35854 * makeusg.adb: Document new switch -B
35856 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
35858 * switch-m.adb: (Scan_Make_Switches): Process -B switch

35865 * trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
35868 * misc.c (gnat_printable_name): If VERBOSITY is 2, call
35869 Set_Identifier_Casing.

35872 has size that overflows.
35874 2004-01-05 Gary Dismukes <dismukes@gnat.com>
35876 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
35877 -gnatwa warning on static condition.
35879 2004-01-05 Doug Rupp <rupp@gnat.com>
35881 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
35883 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
35885 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
35886 all attributes, including read-only attribute.
35888 2004-01-05 Pascal Obry <obry@gnat.com>
35890 * bindgen.adb (Gen_Object_Files_Options): Generate the new shared
35891 library naming scheme.
35893 * mlib-prj.adb (Build_Library): Generate different names for the static
35894 or dynamic version of the GNAT runtime. This is needed to support the
35895 new shared library naming scheme.
35896 (Process_Binder_File): Add detection of shared library in binder file
35897 based on the new naming scheme.
35899 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
35900 scheme for the shared runtime libraries.
35903 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
35905 (install-gnatlib): Do not create symlinks for shared libraries.
35906 (gnatlib-shared-default): Idem.
35907 (gnatlib-shared-dual-win32): New target. Not used for now as the
35908 auto-import feature does not support arrays/records.
35909 (gnatlib-shared-win32): Do not create copy for the shared libraries.
35910 (gnatlib-shared-vms): Fix shared runtime libraries names.
35912 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
35913 dependent runtime shared library name.
35915 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
35917 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
35920 2004-01-05 Ed Schonberg <schonberg@gnat.com>
35922 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
35923 protected objects when allocator has a subtype indication, not a
35924 qualified expression. Note that qualified expressions may have to be
35925 checked when limited aggregates are implemented.
35927 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
35928 pure, emit warning.
35929 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
35930 subprogram is imported, remove warning.
35932 2004-01-05 Geert Bosch <bosch@gnat.com>
35934 * s-poosiz.adb: Update copyright notice.
35935 (Allocate): Use Task_Lock to protect against concurrent access.
35936 (Deallocate): Likewise.
35938 2004-01-05 Joel Brobecker <brobecker@gnat.com>
35940 * s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???

35974 * cstand.adb (Create_Standard): Change the way how the declaration of
35975 the Duration type is created (making it the same way as it is for all
35976 the other standard types).

35986 the expression type only if it is declared in the current unit.
35988 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
35989 are universal and already analyzed, as can occur in constrained
35990 subcomponents that depend on discriminants, when one constraint is a
35993 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
35994 type Any_Fixed is legal as the argument of a conversion, if only one

36008 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
36009 (Gnatchop): Do not set failure status when reporting the number of
36012 2003-12-15 Doug Rupp <rupp@gnat.com>
36014 * s-ctrl.ads: New file.

36034 * Make-lang.in: Makefile automatically updated
36036 2003-12-11 Ed Falis <falis@gnat.com>
36038 * 5zinit.adb: Clean up.
36040 * 5zintman.adb (Notify_Exception): replaced case statement with a call
36041 to __gnat_map_signal, imported from init.c to support
36042 signal -> exception mappings that depend on the vxWorks version.
36045 Created and exported __gnat_map_signal to support signal -> exception

36075 Minor reformatting throughout
36077 2003-12-11 Ed Schonberg <schonberg@gnat.com>
36079 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
36080 bounds of a loop, create a separate block in order to generate proper
36081 cleanup actions to prevent memory leaks.
36083 * sem_res.adb (Resolve_Call): After a call to
36084 Establish_Transient_Scope, the call may be rewritten and relocated, in
36085 which case no further processing is needed.
36087 * sem_util.adb: (Wrong_Type): Refine previous fix.
36088 Fixes ACATS regressions.
36091 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
36094 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
36096 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
36097 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
36100 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
36103 2003-12-08 Robert Dewar <dewar@gnat.com>
36105 * 7sintman.adb: Minor reformatting
36107 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
36108 standard linker options to get standard libraries linked. We now plan
36109 to provide dummy versions of these libraries to match the appropriate
36110 configurable run-time (e.g. if a library is not needed at all, provide
36111 a dummy empty library).
36113 * targparm.ads: Configurable_Run_Time mode no longer affects linker
36114 options (-L parameters and standard libraries). What we plan to do is
36115 to provide dummy libraries where the libraries are not required.
36117 * gnatbind.adb: Minor comment improvement
36119 2003-12-08 Javier Miranda <miranda@gnat.com>
36121 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
36122 aggregate in the parent. Otherwise constants with limited aggregates
36123 are not supported. Add new formal to pass the component type (Ctype).
36124 It is required to call the corresponding IP subprogram in case of
36125 default initialized components.
36126 (Gen_Assign): In case of default-initialized component, generate a
36127 call to the IP subprogram associated with the component.
36128 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
36129 of aggregate with default initialized components.
36130 (Has_Default_Init_Comps): Improve implementation to recursively check
36131 all the present expressions.
36133 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
36134 to indicate that the initialization call corresponds to a
36135 default-initialized component of an aggregate.
36136 In case of default initialized aggregate with tasks this parameter is
36137 used to generate a null string (this is just a workaround that must be
36138 improved later). In case of discriminants, this parameter is used to
36139 generate a selected component node that gives access to the discriminant
36142 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
36143 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
36144 allocated aggregates with default-initialized components.
36146 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
36147 the box notation is used in positional aggregates.

36163 * prj-part.adb (With_Record): New component Node
36164 (Parse): New Boolean parameter Store_Comments, defaulted to False.
36165 Set the scanner to return ends of line and comments as tokens, if
36166 Store_Comments is True.
36167 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
36168 comments are associated with these nodes. Store the node IDs in the
36170 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
36172 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
36173 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
36174 current project. Call Tree.Restore afterwards. Set the various nodes
36175 for comment storage (Next_End, End_Of_Line, Previous_Line,
36178 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
36179 defaulted to False.
36181 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
36182 to False. When Truncated is True, truncate the string, never go to the
36184 (Write_End_Of_Line_Comment): New procedure
36185 (Print): Process comments for nodes N_With_Clause,
36186 N_Package_Declaration, N_String_Type_Declaration,
36187 N_Attribute_Declaration, N_Typed_Variable_Declaration,
36188 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
36189 Process nodes N_Comment.
36191 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
36192 without comments and there are some comments, set the flag
36193 Unkept_Comments to True.
36194 (Scan): If there are comments, set the flag Unkept_Comments to True and
36195 clear the comments.
36196 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
36197 (Next_End_Nodes: New table
36198 (Comment_Zones_Of): New function
36199 (Scan): New procedure; moved from Prj. Accumulate comments in the
36200 Comments table and set end of line comments, comments after, after end

36203 (Save, Restore, Seset_State): New procedures
36204 (There_Are_Unkept_Comments): New function
36205 (Set_Previous_Line_Node, Set_Previous_End_Node): New procedures

39953 full stop at the end of a sentence. Use @samp markup when
39954 referring concrete lexical entities (keywords, attribute names
39955 etc.), and @syntax for ARM grammar elements. Use @r for English
39956 text in comments. Use @emph for emphasis. Change "if-statements"

39970 * make.adb (Add_Switch): Make Generic_Position a procedure. The
39971 function approach did not work well because of a side effect (the
39972 function call could reallocate the table which was being indexed
39973 using its result). Fixes ada/4851.

40251 When using a project file, fail if specified executable is relative
40252 path with directory information, and prepend executable, if not

40337 there could be a real problem here with an uninitialized reference
40338 to Hbound, but no actual example of failure has been found.
40340 2001-12-17 Laurent Pautet <pautet@gnat.com>
40343 Fix comment of Shutdown_Socket and Close_Socket. These functions
40344 should not fail silently because if they are called twice, this
40345 probably means that there is a race condition in the user program.
40346 Anyway, this behaviour is consistent with the rest of this unit.
40347 When an error occurs, an exception is raised with the error message
40348 as exception message.

41680 (CRC_Match): new function.
41681 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
41682 instead of the previous simple checksum algorithm.
41683 (Time_Stamp_Mismatch): use CRC_Match for comparison.
41684 (Set_Source_Table): idem.
41687 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
41688 instead of simple checksum.
41689 (CRC_Match): new function.
41690 (CRC_Error): new constant.
41692 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
41693 a CRC now and not a simple checksum. A CRC uses lower-case hex
41694 letters, fixes ambiguity in parsing.
41696 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
41697 is what this variable will store.
41699 * bcheck.adb: Change reference to chechsum in comments by CRC.
41700 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
41701 rename All_Checksum_Match to All_CRC_Match. Change due to API
41702 renaming since now GNAT does not use a simple checksum but a
41703 CRC using GNAT.CRC32.
41705 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
41706 now and not anymore a simple checksum.
41708 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
41711 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.

41719 (Checksum): rename to CRC.
41720 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
41722 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
41723 GNAT.CRC32). Update copyright notice.

41743 Update comments for the CRC.
41745 * types.adb (Hex): Use lowercase for the letter part.
41747 * types.ads (Get_Hex_String): Returns the hexadecimal representation
41748 for a word. This is currently used only for CRC. In previous version,
41749 the checksum was using a representation with all letter being
41750 upper-case. With the new implementation (using CRC) we do not remove
41751 the 32th bit of the CRC, so we can have an upper-case starting letter
41752 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
41753 It is ambigous since the CRC was optional and could be followed by
41754 options like EB, EE. So now this routines uses lower-case letter for
41755 the hexadecimal representation. Strange enough only lower case letters
41756 where checked in Scan_ALI (even if this was not a possible case).
41758 * gnatvsn.ads (Library_Version): changed to 3.15a.
41760 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
41763 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

41767 Add 2001 to copyright notice
41768 (Accumulate_Checksum): Modify to use System.CRC32.
41770 * ali-util.ads: Redo changes of previous revision to continue to use
41771 the word Checksum. Add 2001 to copyright notice.

41774 Keep the change for lower case letters in the checksum.
41776 * ali.ads: Undo previous change not needed.
