401 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
402 Orig_Prev to Prev in the case where the actual is N_Function_Call or
403 N_Identifier. This was interfering with other cases that are rewritten
404 as N_Identifier, such as allocators, resulting in passing of the wrong
405 accessibility level, and based on testing this code is apparently no
406 longer needed at all.
408 2008-08-01 Ed Schonberg <schonberg@adacore.com>
410 * sem_ch4.adb (Analyze_One_Call): Handle complex overloading of a

2497 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
2498 convention from its base type, do not set the type to that of integer,

2565 New local subprogram Is_Valid_Remote_Object_Type, replaces
2566 Is_Recursively_Limited_Private.

2577 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
2578 Is_Remote_Call_Interface to identify RACW types in a stable and
2579 consistent way. We used to rely in this predicate on the privateness of
2580 the designated type and its ancestors, but depending on the currently
2581 visible private parts, this caused false negatives. We now uniformly
2582 rely on checks made at the point where the RACW type is declared.

2596 Add missing escaping of all-caps word 'CPP' in error messages.
2597 (Build_Discriminated_Subtype): Do not inherit representation clauses
2598 from parent type if subtype already carries them, because they are
2599 inherited earlier during derivation and already include those that may
2600 come from a partial view.
2602 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
2603 Check the declarations of a subprogram body for proper deferred

2638 operation of an RACW stub type (these primitives are only executed
2639 through dispatching, never through static calls).
2640 (Collect_Interps): When only one interpretation has been found, set N's
2641 Entity and Etype to that interpretation, otherwise Entity and Etype may
2642 still refer to an interpretation that was ignored by Add_One_Interp,
2643 in which case would end up with being marked as not overloaded but with
2644 an Entity attribute not pointing to its (unique) correct interpretation.

2703 equivalent representation, but has the advantage of allowing
2704 compilation of this file under 64 bits platforms.

6904 WITH clause on a private sibling.
6905 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
6906 child unit is a renaming, create an implicit with_clause on that
6907 parent, and not on the unit it renames, to prevent visibility errors

6974 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
6975 type from a limited_with_clause, and the full view is available, use it

7006 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
7007 requeue statement is dispatching. Do not emit an error when the name is

7009 perform subtype conformance between the formals of the current entry
7010 and those of the target interface primitive.
7011 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
7012 Timed_Entry_Call): Analyze the triggering statement as the first step of
7013 the processing. If this is a dispatching select, postpone the analysis
7014 of all select statements until the Expander transforms the select. This

7016 replicated some of the select statements. In case the Expander is
7017 disabled, perform regular analysis.
7018 (Check_Triggering_Statement): New routine.
7019 (Analyze_Requeue): Exclude any interpretations that are not entries when
7020 checking overloaded names in a requeue. Also test type conformance for

7026 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
7027 inherited operation is a defaulted tag-indeterminate call, and there is

7029 for the defaulted actual.
7031 2007-12-13 Geert Bosch <bosch@adacore.com>
7033 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

7058 latest Ada 2005 rules about renaming and 'Access of
7059 discriminant-dependent components.

7613 a predefined entity (as happens for array index types), the line is set
7615 Add support for parsing multiple array index types info, or
7616 multiple inherited interfaces info. This information cannot be stored
7617 in Xref_Entity_Record, which only supports a single instance of Tref_*,

7633 Dismukes). After this patch there is no need to perform any
7634 additional management on these nodes in Expand_Interface_Actuals.
7636 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
7637 that handles use of 'Access and 'Unchecked_Access applied to
7638 actuals covering interface types. Such code is now
7639 centralized in Expand_N_Attribute_Reference.
7641 2007-10-15 Ed Schonberg <schonberg@adacore.com>

7683 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
7684 used by VxWorks targets to have access to task-specific data and be
7685 able to extract the stack boundaries for stack checking.

7729 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
7730 association for an access component, add an association with null as
7731 the expression. Remove testing for array subtypes and the setting in
7732 that case of Ctyp to the array component type, which prevented proper
7733 inclusion of an association for null-initialized arrays. Collapse
7734 condition that tests for array subtypes into just a test of
7735 Is_Partially_Initialized_Type (which already covers arrays anyway).

7748 on the parent subtype and any new set of discriminants.
7750 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
7752 * sem_ch4.adb: Minor code and comment reformatting.
7753 (Analyze_Allocator): When the designated type of an unconstrained
7754 allocator is a record with unknown discriminants or an array with
7755 unknown range bounds, emit a detailed error message depending on the
7756 compilation mode and whether the designated type is limited.

7889 type of file_info_ptr parameter.
7890 If mapped location support is enabled, create the isomorphic mapping
7891 between source files and line maps.
7892 (Sloc_to_locus): If mapped location support is enabled, translate
7893 source location into mapped location.

7921 Add a section on leap seconds control along with two entities used to
7922 enable and disable leap seconds support. The array Leap_Second_Times is
7923 now constant and contains hard time values pre-generated. Remove
7924 all elaboration code used to populate the table of leap seconds.
7927 Add entity Leap_Seconds_Support to the list of global run-time variables
7928 along with a comment on its usage and values.

7984 2007-09-26 Javier Miranda <miranda@adacore.com>
7985 Eric Botcazou <ebotcazou@adacore.com>
7988 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
7989 indirection added to the HT_Link component of the TSD. This is required
7990 to statically allocate the TSD.
7993 Minor reordering of the declarations in the private part. Required to
7994 add a level of indirection to the contents of the TSD component HT_Link.
7995 This is required to statically allocate the TSD.
7997 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
7998 Is_Statically_Allocated set from constant objects.
7999 Do not make exported constants created by the compiler volatile.
8000 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
8003 * trans.c (Identifier_to_gnu): For constants, unshare initializers
8004 before returning them.
8006 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
8007 public part of the package.
8008 (Make_DT): Move HT_Link component out of the TSD record. For this
8009 purpose Make_DT now declares a separate object that stores the
8010 HT_Link value, and initializes the TSD component with the address
8011 of this new object. The addition of this level of indirection is
8012 required to statically allocate the TSD because the TSD cannot
8013 have variable components.
8014 (Expand_Interface_Conversion): Improve the expanded code.
8015 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
8017 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
8018 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
8019 if we are building static dispatch tables then we must not generate
8020 extra code to register the primitive because the dispatch table will
8021 be built at the end of the library package; otherwise we notify that
8022 we cannot build the static dispatch table.
8024 2007-09-26 Robert Dewar <dewar@adacore.com>
8026 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

8041 for thunks associated with interface types.
8043 * einfo.ads: Improve documentatation of Is_Internal
8044 (Is_Thunk): New attribute applicable to subprograms. True for thunks
8045 associated with interface types.
8046 Extensive comment fixes regarding flags that appear in all entities. The
8047 documentation is now consistent for all such flags (there were a number
8048 of errors in the documentation in this regard).
8050 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
8052 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
8053 of these procedures are passed a function call that already has
8054 build-in-place actuals (testing new flag
8055 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
8056 the case where processing continues.
8057 (Expand_Call): If the call is generated from a thunk body then we
8058 propagate the extra actuals associated with the accessibility
8059 level of the access type actuals.
8061 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
8062 of each extra formal of a protected operation to reference the
8063 corresponding extra formal of the subprogram denoted by the
8064 operation's Protected_Body_Subprogram.
8066 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
8067 N_Function_Call nodes.
8069 2007-09-26 Robert Dewar <dewar@adacore.com>
8071 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
8073 * debug.adb: Add d.s flag.

8077 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
8078 debug variable so that it won't be initialized when pragma
8079 Initialize_Scalars is in effect.
8081 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8083 * freeze.adb (Freeze_Entity): Remove check for preelaborable
8084 initialization of a full view. This is moved to
8085 Analyze_Package_Specification.
8087 * sem_ch7.adb (Analyze_Package_Specification): Add check for
8088 preelaborable initialization of a full view in entity loop.
8089 (Uninstall_Declarations): If entity is a use-visible compilation unit,
8090 its child units are use-visible only if they are visible child units.
8092 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
8093 whether an expression can be used within a type declaration that
8094 requires preelaborable init.
8095 (Check_Components): Replace inline code that does partial checking for
8096 preelaborable default expressions with call to
8097 Is_Preelaborable_Expression.
8098 (Has_Preelaborable_Initialization): In the case of a generic actual
8099 subtype, (that is, Is_Generic_Actual is True), return the result of
8100 applying Has_Preelaborable_Initialization to the generic actual's base
8103 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
8105 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
8106 call to Jan_1_Day _Of_Week to optimize its performance.
8107 (Is_Leap): Move the routine to the scope of Week_In_Year.
8108 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
8109 weekday on which January 1 falls of Year - 1 and Year + 1. This function
8110 avoids calling Time_Of and Split, thus making it more efficent.
8111 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
8113 * g-calend.ads (Week_In_Year): Change comment to reflect new
8116 2007-09-26 Emmanuel Briot <briot@adacore.com>

8119 Command_Line): New types
8120 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
8121 support for defining how switches can be grouped on a command line (as
8122 is the case for -gnatw... for GNAT), and how simple switches can be
8123 used as aliases for more complex switches (-gnatwa is same as
8125 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
8126 (Start, Current_*): New subprograms
8127 Added support for parsing an array of strings in addition to the real
8129 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
8130 be moved from the body to the private part of the spec.
8131 (*): All subprograms now have an extra parameter with default value to
8132 specify which parser should be used. For backward compatibility, it
8133 defaults to parsing the command line of the application. They were also
8134 modified to properly handle cases where each of the argument does not
8135 start at index 1 (which is always true for Ada.Command_Line, but not
8136 when processing any Argument_List).
8137 (Free): New subprogram
8138 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
8139 Argument): New subprograms
8140 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
8141 special characters like ':', '=',... are now handled in a single place,
8142 which makes the code more extensible eventually.
8143 (Getopt, Full_Switch): When the switch was returned as part of the
8144 special character '*', make sure it is prepended by the switch character
8145 ('-' in general), so that the application knows whether "foo" or "-foo"
8146 was specified on the command line.
8148 2007-09-26 Florian Villoing <villoing@adacore.com>
8150 * g-dirope.adb (Remove_Dir): In case we are removing directories
8151 recursively, make sure that if an exception is raised during the
8152 processing, the current working directory is reset to its initial
8153 value before propagating the exception.
8155 2007-09-26 Vincent Celier <celier@adacore.com>
8157 * gnatbind.adb: If there are several ALI files specified and there is
8158 a main program to bind, the first ALI is expected to contain the main
8159 subprogram and the names of the binder generated files will be derived
8160 from the first ALI file name.
8161 (Gnatbind): Fix insertion character in invocation of Error_Msg
8163 2007-09-26 Vincent Celier <celier@adacore.com>
8165 * gnatcmd.adb (Check_Files): Do not include sources that have been
8166 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
8168 2007-09-26 Ed Schonberg <schonberg@adacore.com>
8170 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
8171 information about each of its index types, following the type
8172 reference for its component type.
8174 2007-09-26 Vincent Celier <celier@adacore.com>
8176 * make.adb: (Kill): New procedure (__gnat_kill imported)

8187 2007-09-26 Vincent Celier <celier@adacore.com>
8189 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
8191 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
8192 Replace components Compiler_Min_Options and Binder_Min_Options with
8193 Compiler_Required_Switches and Binder_Required_Switches in record

8198 * prj-attr.adb: New attributes Required_Switches (<language>) in
8199 packages Compiler and Binder.
8201 * prj-nmsc.adb: Major rewrite of the processing of configuration
8202 attributes for gprbuild. No impact on GNAT tools.
8204 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

8236 2007-09-26 Ed Schonberg <schonberg@adacore.com>
8238 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
8239 ancestor of the derived type, the operations are inherited from the
8240 primary dispatch table of the parent.
8241 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
8242 when the context is an explicit type conversion.
8244 2007-09-26 Ed Schonberg <schonberg@adacore.com>

8546 body for 'Output when the type is abstract (only the creation of the
8547 body for 'Input is excluded when the type is abstract).

8549 statement, so that False will be returned for TTS_Stream_Input if the
8550 associated tagged type is an abstract extension. Add comments for

8553 variable, insert init proc call only after the shared variable
8554 procedures have been processed, because the IP call needs to undergo

8568 type, retrieve its value from the aggregate itself, where it must have
8571 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
8572 to remove other spurious ambiguities on arithmetic operations involving
8573 literals and addresses, on systems where Address is a visible integer
8574 type, when the operator is called in functional notation.

8701 (Write_Entity_Flags): Write the status of flag Is_Raised.
8702 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
8703 spurious ambiguities when integer literals appear in the context of an
8704 address type that is a visible integer type.
8706 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
8707 exceptions never being raised.
8708 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

8724 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
8725 library-level package renaming, pass the declaration associated with
8726 the renaming's special debug variable to Qualify_Entity_Names to ensure
8727 that its encoded name is properly qualified.
8729 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
8730 occurring in the list of entities to qualify, and do not attempt to
8731 traverse an entity list in that case. Variables associated with
8732 ` library-level package renamings can now occur in the table.
8734 * exp_dbug.ads: Revise documentation of the encoding for renaming

8751 to include loop parameters.
8752 (Valid_Conversion): Avoid generation of spurious error message.

8756 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
8757 concatenations of string literals into a single literal, in order to
8758 avoid very deep recursion in the front end, which was causing stack
8761 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
8762 string, and the right operand is a string literal (the case of "" &
8763 "..."), optimize by avoiding copying the right operand -- just use the
8764 value of the right operand directly.
8766 * stringt.adb (Store_String_Chars): Optimize by growing the
8767 String_Chars table all at once, rather than appending characters one by
8769 (Write_String_Table_Entry): If the string to be printed is very long,
8770 just print the first few characters, followed by the length. Otherwise,
8771 doing "pn(n)" in the debugger can take an extremely long time.
8773 * sem_prag.adb (Process_Interface_Name): Replace loop doing
8774 Store_String_Char with Store_String_Chars.

8789 have not been fully analyzed.
8791 2007-08-31 Ed Schonberg <schonberg@adacore.com>
8793 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
8794 flag, for effiency. It is called when analyzing arithmetic operators
8795 and also for actuals in calls that are universal_integers. The flag is
8796 set for the predefined type address, and for any type or subtype
8799 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
8800 Universal_Integer, when the formal is a descendent of address and the
8801 call appears in user code.

8868 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
8869 associated with Standard_Debug_Renaming_Type, to be used as the type of
8870 the special variables whose names provide debugger encodings for
8871 renaming declarations.
8873 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
8874 (Set_Debug_Renaming_Link): Change to set Node25.

8881 (Debug_Renaming_Declaration): Replace creation of an enumeration type
8882 and literal with creation of a variable of type
8883 Standard_Debug_Renaming_Type whose name encodes both the renamed object
8884 and the entity of the renaming declaration.
8885 (Qualify_Entity_Name): Add the delayed qualification of the entity name
8886 part of the name of a variable that has a Debug_Renaming_Link.

8893 Ed Schonberg <schonberg@adacore.com>
8894 Javier Miranda <miranda@adacore.com>
8896 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
8897 ancestor part given by an aggregate to test for an unchecked conversion,
8898 since this can occur in some cases when the ancestor part is a function
8899 call, and we don't want to fall into the recursive call to this
8900 procedure in that case.
8902 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
8903 stream attributes on limited types to account for user-specified
8904 attributes as well as whether Input (resp. Output) becomes available
8905 due to Read (resp. Write) being available for the type. Change Boolean
8906 variable to the more accurate name
8907 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
8908 double-"not" predicate at beginning of return statement to more
8909 understandable form.
8911 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
8912 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
8913 in a block statement and use that as the first statement of the
8914 expanded return rather than incorrectly using the handled sequence as
8915 the first statement.
8917 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
8918 operation, generate an explicit freeze node for it rather than
8919 generating extra formals, to ensure that gigi has the proper order of
8920 elaboration for anonymous subtypes in the signature of the subprograms.
8921 (Build_In_Place_Formal): Move assertion to beginning of loop.
8922 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
8923 applied to a function call (occurs for some cases of 'Input).
8924 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
8925 applied to a function call (occurs for some cases of 'Input).
8927 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
8928 2005, generate an extended return statement enclosing the result object
8931 * freeze.adb (Freeze_Record_Type): Extend the current management of
8932 components that are access type with an allocator as default value: add
8933 missing support to the use of qualified expressions of the
8934 allocator (which also cause freezing of the designated type!)
8935 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
8936 dispatching operation, since extra formals may be needed by calls to
8937 build-in-place functions (such as stream 'Input).
8939 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
8940 formals for 'Constrained and accessibility level in the case of a
8941 predefined dispatching operation.
8943 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
8944 point, no need to find the parent node.
8946 2007-08-16 Javier Miranda <miranda@adacore.com>
8948 * exp_attr.adb (Attribute_Priority): Add missing support for entries
8951 2007-08-16 Javier Miranda <miranda@adacore.com>
8953 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
8954 is not really required and can introduce regression with the debugger.
8955 The original problem is fixed with the patch written for checks.adb.
8957 2007-08-16 Thomas Quinot <quinot@adacore.com>
8959 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

8967 Including_Non_Switch set to False.
8969 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
8970 parameter Including_Non_Switch, defaulted to True. When
8971 Including_Non_Switch is False, options that are not switches and
8972 appear as relative path are not converted to absolute paths.

8988 (Install_Limited_Withed_Unit): Do not install the limited view of
8989 package P if P is reachable through an ancestor chain from package C
8990 and C also has a with clause for P in its body.
8991 (Has_Limited_With_Clause): New routine.
8992 (Has_With_Clause): New routine.
8994 2007-08-16 Ed Schonberg <schonberg@adacore.com>
8996 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
8997 generic for an enclosing instance is a global reference, even though
8998 its scope is the enclosing instance.

9001 Javier Miranda <miranda@adacore.com>
9003 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

9021 Bob Duff <duff@adacore.com>
9022 Nicolas Setton <setton@adacore.com>
9024 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
9025 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
9026 the statement which is being resolved comes from a predefined library
9027 unit, all non-predefined library interpretations are skipped.
9028 (Resolve_Op_Concat): If string concatenation was folded in the parser,
9029 but the "&" is user defined, give an error, because the folding would
9032 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
9033 the parser has folded a long sequence of concatenations of string
9036 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
9037 and "JMP_BUF" variables as artificial.
9038 (N_String_Literal): Do not use alloca for very long string literals. Use

9092 needed for access to concurrent record types generated by the expander.
9093 (Generate_Range_Check): When generating a temporary to capture the
9094 value of a conversion that requires a range check, set the type of the
9095 temporary before rewriting the node, so that the type is always
9096 properly placed for back-end use.
9097 (Apply_Float_Conversion_Check): Handle case where the conversion is
9099 (Get_Discriminal): Code reformatting. Climb the scope stack looking

9115 (Expand_N_Type_Conversion): Test for the case of renamings of access
9116 parameters when deciding whether to apply a run-time accessibility
9118 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
9119 aggregate code before allocator, and ahead of declaration for
9120 temporary, to prevent access before elaboration when the allocator is
9121 an actual for an access parameter.
9122 (Expand_N_Type_Conversion): On an access type conversion involving an
9123 access parameter, do not apply an accessibility check when the
9124 operand's original node was an attribute other than 'Access. We now
9125 create access conversions for the expansion of 'Unchecked_Access and
9126 'Unrestricted_Access in certain cases and clearly accessibility should
9127 not be checked for those.
9129 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
9130 includes a type conversion of a packed component that has been expanded,
9131 recover the original expression for the object, and use this expression
9132 in the post-call assignment statement, so that the assignment is made
9133 to the object and not to a back-end temporary.
9134 (Freeze_Subprogram): In case of primitives of tagged types not defined
9135 at the library level force generation of code to register the primitive
9136 in the dispatch table. In addition some code reorganization has been
9137 done to leave the implementation clear.

9139 preserve the type of the inherited function after the intrinsic
9140 operation has been expanded.
9142 * exp_ch2.ads, exp_ch2.adb
9143 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
9144 of an entry formal appearing in an assignment statement does not assign
9146 (Expand_Current_Value): Instead of calling a routine to determine
9147 whether the prefix of an attribute reference should be optimized or
9148 not, prevent the optimization of such prefixes all together.
9150 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
9151 component whose prefix is known to be of an access type is an implicit
9152 dereference and does not assign to the prefix.

9162 the corresponding range construct, and not to the aggregate itself. to
9163 maintain a one-to-one correspondence between itype and its associated
9164 node, to prevent errors when complex expression is copied.
9165 Fix mishandling of multiple levels of parens

9168 treatment of limited views uniform for all visible declarations in a
9169 limited_withed package.
9170 (New_Copy_Tree): If hash table is being used and itype is visited,
9171 make an entry into table to link associated node and new itype.
9172 (Resolve_Record_Aggregate): Do not add an others box association for a
9173 discriminated record component that has only discriminants, when there
9174 is a box association for the component itself.
9176 * par-ch4.adb: Fix mishandling of multiple levels of parens

9211 Javier Miranda <miranda@adacore.com>
9212 Gary Dismukes <dismukes@adacore.com>
9214 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
9215 to make treatment of limited views uniform for all visible declarations
9216 in a limited_withed package.
9217 Improve warnings for in out parameters
9218 (Set_Related_Interaface/Related_Interface): Allow the use of this
9219 attribute with constants.
9220 (Write_Field26_Name): Handle attribute Related_Interface in constants.
9221 Warn on duplicate pragma Preelaborable_Initialialization
9223 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
9224 generation of a freezing node to ensure proper management of null
9225 excluding access types in the backend.
9226 (Create_Extra_Formals): Test base type of the formal when checking for
9227 the need to add an extra accessibility-level formal. Pass the entity E
9228 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
9229 originally being done in a couple of cases), to ensure that the
9230 Extra_Formals list gets set on the entity E when the first entity is
9232 (Conforming_Types): Add missing calls to Base_Type to the code that
9233 handles anonymous access types. This is required to handle the
9234 general case because Process_Formals builds internal subtype entities
9235 to handle null-excluding access types.
9236 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9237 functions that need it, even when not marked Requires_Overriding.
9238 Improve warnings for in out parameters
9239 (Analyze_Function_Return): Warn for disallowed null return
9240 Warn on return from procedure with unset out parameter
9241 Ensure consistent use of # in error messages
9242 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
9243 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
9244 the implicit conversion of the expression done for anonymous access
9245 types. This is required to generate the code of the null excluding
9246 check (if required).
9248 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
9249 A formal parameter is never publicly referenceable outside of its body.
9250 (Check_References): For an unreferenced formal parameter in an accept
9251 statement, use the same warning circuitry as for subprogram formal
9253 (Warn_On_Unreferenced_Entity): New subprogram, taken from
9254 Output_Unreferenced_Messages, containing the part of that routine that
9255 is now reused for entry formals as described above.
9256 (Goto_Spec_Entity): New function
9257 (Check_References): Do not give IN OUT warning for dispatching operation
9258 Improve warnings for in out parameters
9259 (Test_Ref): Check that the entity is not undefinite before calling
9260 Scope_Within, in order to avoid infinite loops.
9261 Warn on return from procedure with unset out parameter
9262 Improved warnings for unused variables

9265 Javier Miranda <miranda@adacore.com>
9266 Gary Dismukes <dismukes@adacore.com>
9268 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
9269 (Expand_N_Attribute_Reference): Further unify the handling of the
9270 three forms of access attributes, using common code now for all three
9271 cases. Add a test for the case of applying an access attribute to
9272 an explicit dereference when the context is an access-to-interface
9273 type. In that case we need to apply the conversion to the prefix
9274 of the explicit dereference rather than the prefix of the attribute.
9275 (Attribute_Version, UET_Address): Set entity as internal to ensure
9276 proper dg output of implicit importation.
9277 (Expand_Access_To_Type): Removed.
9278 (Expand_N_Attribute_Reference): Merge the code from the three cases
9279 of access attributes, since the processing is largely identical for
9280 these cases. The substantive fix here is to process the case of a
9281 type name prefix (current instance case) before handling the case
9282 of interface prefixes.
9284 2007-08-14 Thomas Quinot <quinot@adacore.com>
9285 Ed Schonberg <schonberg@adacore.com>
9286 Javier Miranda <miranda@adacore.com>
9287 Robert Dewar <dewar@adacore.com>
9289 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
9290 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
9291 type that is an anonymous access to controlled object, establish
9292 an associated finalization chain to avoid corrupting the global
9293 finalization list when a dynamically allocated object designated
9294 by such a component is deallocated.
9295 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9296 functions that need it, even when not marked Requires_Overriding.
9297 (Initialize_Tag): Replace call to has_discriminants by call to
9298 Is_Variable_Size_Record in the circuitry that handles the
9299 initialization of secondary tags.

9301 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
9302 Suppress_Initialization pragma for a derived type.
9303 (Is_Variable_Size_Record): New subprogram.
9304 (Build_Offset_To_Top_Functions): New implementation that simplifies the
9305 initial version of this routine and also fixes problems causing
9306 incomplete initialization of the table of interfaces.
9307 (Build_Init_Procedure): Improve the generation of code to initialize the
9308 the tag components of secondary dispatch tables.
9309 (Init_Secondary_Tags): New implementation that simplifies the previous
9310 version of this routine.
9311 (Make_DT): Add parameter to indicate when type has been frozen by an
9312 object declaration, for diagnostic purposes.
9313 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
9314 diagnose attemps to freeze a subprogram when some untagged type of its
9315 profile is a private type whose full view has not been analyzed yet.
9316 (Freeze_Array_Type): Generate init proc for packed array if either
9317 Initialize or Normalize_Scalars is set.
9318 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
9319 constructing the new profile, copy the null_exclusion indicator for each
9320 parameter, to ensure full conformance of the new body with the spec.
9322 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
9323 Create wrappers for constructor functions that need it, even when not
9324 marked Requires_Overriding.
9325 (Covers): Handle properly designated types of anonymous access types,
9326 whose non-limited views are themselves incomplete types.
9327 (Add_Entry): Use an entity to store the abstract operation which hides
9329 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
9330 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
9331 initialization aggregate.
9332 (Function_Interp_May_Be_Hidden): Rename to
9333 Function_Interp_Has_Abstract_Op.
9334 (Has_Compatible_Type): Remove machinery that skips interpretations if
9335 they are labeled as potentially hidden by an abstract operator.
9336 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
9337 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
9338 (Write_Overloads): Output the abstract operator if present.
9339 (Add_Entry): Before inserting a new entry into the interpretation table
9340 for a node, determine whether the entry will be disabled by an abstract
9342 (Binary_Op_Interp_May_Be_Hidden): New routine.
9343 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
9345 (Function_Interp_May_Be_Hidden): New routine.
9346 (Has_Compatible_Type): Do not consider interpretations hidden by
9347 abstract operators when trying to determine whether two types are
9349 (Has_Hidden_Interp): New routine.
9350 (Set_May_Be_Hidden_Interp): New routine.
9351 (Write_Overloads): Write the status of flag May_Be_Hidden.
9353 2007-08-14 Ed Schonberg <schonberg@adacore.com>
9354 Javier Miranda <miranda@adacore.com>
9356 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
9357 types declared in the declarative part of a nested package body or in
9358 the proper body of a stub.

9364 output of implicit importation and exportation.
9365 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
9366 first formal of the thunk is always associated with the controlling
9367 type. In addition perform the following code cleanup: remove formal
9368 Thunk_Alias which is no longer required, cleanup evaluation of the
9369 the controlling type, and update the documentation.
9370 Replace occurrence of Default_Prim_Op_Count by
9371 Max_Predef_Prims. Addition of compile-time check to verify
9372 that the value of Max_Predef_Prims is correct.
9373 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
9374 (Make_DT): Add parameter to indicate when type has been frozen by an
9375 object declaration, for diagnostic purposes.

9377 construction of statically allocated dispatch tables.
9378 (Make_DT): In case of library-level tagged types export the declaration
9379 of the primary tag. Remove generation of tags (now done by Make_Tags).
9380 Additional modifications to handle non-static generation of dispatch
9381 tables. Take care of building tables for asynchronous interface types
9382 (Make_Tags): New subprogram that generates the entities associated with
9383 the primary and secondary tags of Typ and fills the contents of Access_
9384 Disp_Table. In case of library-level tagged types imports the forward
9385 declaration of the primary tag that will be declared later by Make_DT.
9386 (Expand_Interface_Conversion): In case of access types to interfaces
9387 replace an itype declaration by an explicit type declaration to avoid
9388 problems associated with the scope of such itype in transient blocks.
9390 2007-08-14 Robert Dewar <dewar@adacore.com>
9391 Ed Schonberg <schonberg@adacore.com>
9392 Javier Miranda <miranda@adacore.com>
9394 * exp_util.ads, exp_util.adb:
9395 This patch replaces a number of occurrences of explicit tests for N_Null
9396 with calls to Known_Null. This improves tracking of null values, since
9397 Known_Null also catches null constants, and variables currently known to
9398 be null, so we get better tracking.
9399 (Ensure_Defined): create an itype reference only in the scope of the
9401 (Side_Effect_Free): A selected component of an access type that
9402 denotes a component with a rep clause must be treated as not
9403 side-effect free, because if it is part of a linked structure its
9404 value may be affected by a renaming.
9405 (Expand_Subtype_From_Expr): For limited objects initialized with build
9406 in place function calls, do nothing; otherwise we prematurely introduce
9407 an N_Reference node in the expression initializing the object, which
9408 breaks the circuitry that detects and adds the additional arguments to
9409 the called function. Bug found working in the new patch for statically
9410 allocated dispatch tables.
9411 (Is_Library_Level_Tagged_Type): New subprogram.
9412 (Remove_Side_Effects): If the expression of an elementary type is an
9413 operator treat as a function call.
9414 (Make_Literal_Range): If the index type of the array is not integer, use
9415 attributes properly to compute the constraint on the resulting aggregate
9418 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
9419 class-wide type whose base type is an incomplete private type, leave
9420 class-wide type unfrozen so that freeze nodes can be generated
9421 properly at a later point.
9422 (Freeze_Entity, array case): Handle case of pragma Pack and component
9423 size attributre clause for same array.

10072 operations in Derive_Subprograms.
10073 (Collect_Previous_Instances): new procedure within of
10074 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
10075 unit being loaded, to ensure that the generation of global symbols is

10077 (Is_Tagged_Ancestor): New function testing the ancestor relation that
10078 takes progenitor types into account.
10079 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
10080 traversing over the primitives of the formal and actual types to locate
10081 any abstract subprograms of the actual type that correspond to a
10082 nonabstract subprogram of the formal type's ancestor type(s), and issue
10083 an error if such is found.
10084 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,

10086 Remove bogus guard around calls to Inherit_Context.

10096 parameter to determine whether operation applies to the prefix.
10097 (Complete_Object_Operation): If actual has an access type and
10098 controlling formal is not an in_parameter, reject the actual if it is
10099 an access_to_constant type.
10100 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
10101 type, the candidate operations are found in the scope of declaration of
10102 the type, because the type has no primitive subprograms.
10103 (Analyze_Selected_Component): If prefix is class-wide, and root type is
10104 a private extension, only examine visible components before trying to
10105 analyze as a prefixed call.
10106 Change Entity_List to Type_To_Use, for better readability.
10107 (Has_Fixed_Op): Use base type when checking whether the type of an

10116 formal At_Any_Place indicating, when True, that we want to test for
10117 availability of the stream attribute at any place (as opposed to the
10118 current visibility context only).
10119 (Missing_Read_Write_Attributes): A stream attribute is missing for the
10120 purpose of enforcing E.2.2(8) only if it is not available at any place.
10121 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
10122 when checking the legality of an extension aggregate in a preelaborable
10123 package. Treat the literal null as a valid default expression in a
10124 component declaration for a type with preelaborable initialization.
10125 A limited interface is a legal progenitor for the designated type of a
10126 remote access to class-wide type.

10140 views that are themselves incomplete types.
10141 Handle interfaces visible through limited-with clauses.
10142 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
10143 subprogram generic actual for which we have generated a renaming.
10144 Warn when the renaming introduces a homonym of
10145 the renamed entity, and the renamed entity is directly visible.

11341 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
11342 applicable to types that have the With_Type flag set. Returns the
11343 non-limited view of the type, if available, otherwise the type itself.
11344 For class-wide types, there is no direct link in the tree, so we have
11345 to retrieve the class-wide type of the non-limited view of the Etype.
11346 New attributes Static_Initialization and Static_Elaboration_Desired.

11368 tagged type, do not consider subprograms labeled as hidden unless they
11369 belong to a private generic type with a tagged parent.
11370 (Try_Object_Operation): Extensive rewriting, to handle properly various
11371 overloading cases, when several ancestors may have class-wide operations
11372 that are possible candidates, and when the overloaded functions return
11373 array types and have defaulted parameters so that the call may be
11374 interpreted as an indexing.
11375 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
11376 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
11377 successive actuals before analyzing the call itself.
11378 (Try_Primitive_Operation): A primitive operation is compatible with the
11379 prefix if the prefix has a synchronized type and the type of the formal
11380 is its corresponding record, as can be the case when the primitive
11381 operation is declared outside of the body of the type.
11382 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
11383 perform homonym traversal, looking for class-wide operation matches
11384 (formerly done in statements of Try_Class_Wide_Operation). Matches on
11385 access parameters are now restricted to anonymous access types.
11386 (Mark_Allocator): An allocator with a discriminant association parent is
11388 (Try_One_Prefix_Interpretation): If the type of the object is
11389 incomplete, as can be happen when it is a limited view obtained through
11390 a limited_with_clause, the selected component is not part of a prefixed
11392 (Complete_Object_Operation): Diagnose properly an object that is not
11393 aliased when the corresponding controlling formal is an access
11395 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
11396 ambiguous calls in prefixed notation, where two primitives differ only
11397 in that the controlling argument of one is an access parameter.
11399 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
11400 whether a function that returns an unconstrained type can be inlined.
11401 (Process_Formals): Diagnose properly the illegal use of an incomplete
11402 type in the profile of an access_to_subprogram declaration.
11403 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
11404 operations are attached to the corresponding record.
11405 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
11406 When processing a primitive of a concurrent type which implements an
11407 interface change the type of all controlling formals to that of the
11408 corresponding record type.
11409 (Check_Synchronized_Overriding): Relax the conditional logic when trying
11410 to determine the tagged type to which a primitive belongs.
11411 (Check_Conventions): Capture condition to ignore a primitive operation
11412 (which is shared between the loop in Check_Conventions and the one in
11413 Check_Convention) in a new local function Skip_Check.
11414 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
11415 confusion with Check_Conventions' own Prim_Op local variable.
11416 (Create_Extra_Formals): Test for a tagged result type rather than a
11417 controlling result when determining whether to add a BIP_Alloc_Form
11418 formal and a BIP_Final_List formal to the function.
11419 (Check_Conformance); For parameters that are anonymous access types,
11420 subtype conformance requires that the not null and the constant
11421 indicators must match
11422 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
11423 to retrieve the appropriate type when processing a concurrent type
11424 declared within a generic. Minor comment reformatting. Change invocation
11425 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
11427 (Analyze_Subprogram_Body): If the return type of a function is an
11428 anonymous access to the limited view of a class-wide type, and the
11429 non-limited view of the type is available, update the type of the
11430 function so that code can be generated.
11431 (Process_Formals): In case of access-subtype itype whose designated
11432 type is also an itype (situation that happens now with access to
11433 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
11434 attribute to avoid backend problems.
11435 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
11436 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
11437 anonymous types' designated types are same before testing
11438 Subtypes_Statically_Match.
11439 (Create_Extra_Formals): Test for a named access parameter that is a
11440 controlling formal as an additional condition for adding an
11441 accessibility level formal. This can occur in the subp type created for
11442 dispatching calls in Expand_Dispatching_Call, and allows calling
11443 Create_Extra_Formals from that procedure rather than special-casing the
11444 extra formals there.
11445 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
11446 when the function has a controlling result.
11447 (Check_Returns): Add much more knowledge of the optimization of local
11448 raise statements to gotos, to retain proper warnings in this case.
11449 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
11450 nodes when looking for last statement.
11452 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
11453 class-wide types visible through limited with clauses.
11454 (Add_One_Interp): If the operands are anonymous access types, the
11455 predefined operator on universal_access is immediately visibles
11456 (Find_Unique_Type): Handle anonymous access to subprogram types just as
11457 other anonymous access types.
11458 (Disambiguate): Take into account CIL convention.
11459 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
11461 2007-06-06 Robert Dewar <dewar@adacore.com>
11463 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
11464 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
11465 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
11466 Fix lower bound of tables.
11469 * nlists.adb: Ditto.
11470 (Prev_Node, Next_Node): Change index type to Int so that it properly
11471 covers the range First_Node_Id - 1 up.
11473 2007-06-06 Javier Miranda <miranda@adacore.com>
11474 Ed Schonberg <schonberg@adacore.com>
11475 Bob Duff <duff@adacore.com>
11476 Hristian Kirtchev <kirtchev@adacore.com>
11478 * exp_aggr.ads, exp_aggr.adb:
11479 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
11480 in extension aggregates.
11481 (Flatten): Other conditions being met, an aggregate is static if the
11482 low bound given by component associations is different from the low
11483 bound of the base index type.
11484 (Packed_Array_Aggregate_Handled): If the component type is itself a
11485 packed array or record, the front-end must expand into assignments.
11486 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
11487 Init_Pr, instead of Ancestor_Is_Expression.
11488 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
11489 coextension chain root, either generate a list controller or use the
11490 already existing one.
11491 (Static_Array_Aggregate): New procedure to construct a positional
11492 aggregate that can be handled by the backend, when all bounds and
11493 components are compile-time known constants.
11494 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
11495 types covering interface types into assignments.
11496 (Replace_Type): move to Build_Record_Aggr_Code.
11497 (Expand_Record_Aggr_Code): if the target of the aggregate is an
11498 interface type, convert to the definite type of the aggregate itself,
11499 so that needed components are visible.
11500 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
11501 components and the context is an extended return statement do not
11502 create a transient block for it, to prevent premature finalization
11503 before the return is executed.
11504 (Gen_Assign): Do not generate a call to deep adjust routine if the
11505 component type is itself an array of controlled (sub)-components
11506 initialized with an inner aggregate.
11507 (Component_Check): New name for Static_Check. This name is now more
11508 appropriate, and documentation is added which was missing.
11509 (Component_Check): Add test for bit aligned component value
11510 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
11511 Tagged_Comps, name is more appropriate given added function below.
11512 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

11515 Javier Miranda <miranda@adacore.com>
11516 Robert Dewar <dewar@adacore.com>
11518 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
11519 Terminated: Add unchecked type conversion from System.Address to
11520 System.Tasking.Task_Id when calling the predefined primitive
11522 Disable new Ada 05 accessibility check for JVM.NET targets, which
11523 cannot be implemented in a practical way.
11524 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
11525 the sources always references the tag of the actual object. Therefore,
11526 if 'Tag is applied in the sources to class-wide interface objects we
11527 generate code that displaces "this" to reference the base of the object.
11528 (Expand_N_Attribute_Reference, case Size): Return specified size if
11529 known to front end.
11530 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
11531 has code that displaces the pointer of the object to manage interface
11532 types. However this code must not be executed when the prefix is a
11533 subprogram. This bug caused the wrong expansion of the internally
11534 generated assignment that fills the dispatch table when the primitive
11535 is a function returning a class-wide interface type.
11536 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
11537 Set_Attribute_Name for Name_Unaligned_Valid.
11539 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11540 Gary Dismukes <dismukes@adacore.com>
11542 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
11543 If the initialization is the equivalent aggregate of the initialization
11544 procedure of the type, do not remove it.
11545 (Expand_N_Attribute_Definition_Clause): Exclude access variables
11546 initialized to null from having their expression reset to empty and
11547 note this exception in the comment.

11551 Ed Schonberg <schonberg@adacore.com>
11552 Gary Dismukes <dismukes@adacore.com>
11554 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
11555 Add "with" and "use" clauses for Sem_Attr.
11556 (Expand_Current_Value): Do not replace occurences of attribute
11557 references where the prefix must be a simple name.
11559 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
11560 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
11561 Attribute_Requires_Simple_Name_Prefix.
11562 (Name_Modifies_Prefix): Body of new function.
11563 (Requires_Simple_Name_Prefix): Body of new function.
11564 (Resolve_Attribute, case Access): Improve error message for case of
11565 mismatched conventions.
11566 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
11568 (Analyze_Attribute, case 'Access): If the type of the prefix is a
11569 constrained subtype for a nominal unconstrained type, use its base type
11570 to check for conformance with the context.
11571 (Resolve_Attribute): Remove test of the access type being associated
11572 with a return statement from condition for performing accessibility
11573 checks on access attributes, since this case is now captured by
11574 Is_Local_Anonymous_Access.
11575 (Analyze_Access_Attribute): Set Address_Taken on entity
11576 (Analyze_Attribute, case Address): Set Address_Taken on entity
11577 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
11578 validating an access attribute whose prefix is a current instance.
11579 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
11580 applied to dispatching operations, if freezing is required then we set
11581 the attribute Has_Delayed_Freeze in the prefix's entity.
11582 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
11583 current scope if access of local subprogram taken
11584 (Analyze_Access_Attribute): Check legality of self-reference even if the
11585 expression comes from source, as when a single component association in
11586 an aggregate has a box association.
11587 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
11588 the prefix if it is a protected operation and the attribute is
11589 Unrestricted_Access.
11590 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
11591 reference to the base type of the context, to force a constraint check
11592 when the context is an access subtype with an explicit constraint.
11593 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
11594 node is rewritten as an interface conversion. leave unanalyzed after
11595 resolution, to ensure that type checking against the context will take

11599 Javier Miranda <miranda@adacore.com>
11600 Robert Dewar <dewar@adacore.com>
11602 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
11603 wrapper when the full view of the controlling type of an inherited
11604 function that dispatches on result implements interfaces.
11605 (Expand_N_Object_Declaration): In cases where the type of the
11606 declaration is anonymous access, create finalization list for it.
11607 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
11608 if the object has no explicit initialization, to match description of
11609 functionality of pragam Persistent_BSS.
11610 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
11611 new function to build static aggregates, to replace initialization call
11612 when static initialization is desired.
11613 (Freeze_Type): Generate a list controller for an access type whenever
11614 its designated type has controlled anonymous access discriminants.
11615 (Build_Equivalent_Aggregate): New procedure to compute a static
11616 aggregate to be used as default initialization for composite types,
11617 instead of a generating a call to the initialization procedure for the
11619 (Build_Initialization_Call): When available, replace a call to the
11620 initialization procedure with a copy of the equivalent static aggregate
11622 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
11623 declarations for objects of a class-wide interface type, rather than
11624 just identifiers, to prevent visibility problems.
11625 (Expand_N_Object_Declaration): When expanding the declaration for an
11626 object of a class-wide interface type, preserve the homonym chain of
11627 the original entity before exchanging it with that of the generated
11628 renaming declaration.
11629 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
11630 active, because there is no way to handle the exception.
11631 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
11632 to do a minimum decoration of the Access_Disp_Table list.
11633 (Expand_Record_Controller): Avoid the addition of the controller between
11634 the component containing the tag of a secondary dispatch table and its
11635 adjacent component that stores the offset to the base of the object.
11636 This latter component is only generated when the parent type has
11637 discriminants ---documented in Add_Interface_Tag_Components).
11638 (Apply_Array_Size_Check): Removed, no longer needed.
11639 (Expand_N_Full_Type_Declaration): If the type has anonymous access
11640 components, create a Master_Entity for it only if it contains tasks.
11641 (Build_Init_Procedure): Suppress the tag assignment compiling under
11643 (Freeze_Record_Type): Remove code associated with creation of dispatch
11645 (Init_Secondary_Tags): Update type of actuals when generating calls to
11646 Ada.Tags.Set_Offset_To_Top
11647 (Stream_Operation_OK): Disable use of streams compiling under no
11649 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
11650 if Has_Init_Expression set.
11651 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
11652 Register_Primitive, which provides the same functionality.
11653 (Requires_Init_Proc): Return false in case of interface types.
11654 (Add_Secondary_Tables): Use the new attribute Related_Interface to
11656 (Predefined_Primitive_Freeze): Do not assume that an internal entity
11657 is always associated with a predefined primitive because the internal
11658 entities associated with interface types are not predefined primitives.
11659 Therefore, the call to Is_Internal is replaced by a call to the
11660 function Is_Predefined_Dispatching_Operation.
11661 (Make_Eq_If): When generating the list of comparisons for the
11662 components of a given variant, omit the controller component that is
11663 present if the variant has controlled components.
11665 2007-06-06 Javier Miranda <miranda@adacore.com>
11666 Hristian Kirtchev <kirtchev@adacore.com>
11667 Bob Duff <duff@adacore.com>
11669 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
11670 handle the creation of finalization lists and calls for nested
11671 coextensions when the root of the chains is part of a return statement.
11672 (Inside_A_Return_Statement): New function inside Complete_Coextension_
11674 (Expand_Record_Equality): Skip components that are interface types.
11675 (Displace_Allocator_Pointer): Add missing support for interface subtypes
11676 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
11677 with Rewrite_Coextension. Change the condition for detecting coextension
11679 (Is_Local_Access_Discriminant): Removed.
11680 (Rewrite_Coextension): New routine which rewrites a static coextension
11681 as a temporary and uses its unrestricted access in the construction of
11683 (Complete_Coextension_Finalization): New routine. Generate finalization
11684 attachment calls to all delayed coextensions.
11685 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
11686 the allocator is not a coextension itself and has delayed coextensions.
11687 If the current allocator is controlled, but also a coextension, delay
11688 the generation of the finalization attachment call.
11689 Rename local variable "Node" to "Nod" in order to avoid confusion with
11691 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
11692 limited types that are not inherently limited. Such an allocator is
11693 illegal, but is generated by the expander for a return statement, to
11694 copy the result onto the secondary stack. This is the only case where a
11695 limited object can be copied. Generate code to displace the pointer
11696 to the object if the qualified expression is a class-wide interface
11697 object. Such displacement was missing and hence the copy of the object
11699 (Apply_Accessibility_Check): Handle allocated objects initialized in
11701 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
11702 and Expand_Allocator_Expression. Allocating class-wide interface objects
11703 this routine displaces the pointer to the allocated object to reference
11704 the component referencing the corresponding secondary dispatch table.
11705 Expand_Allocator_Expression): Add missing support to allocate class-wide
11706 interface objects initialized with a qualified expression.
11707 (Get_Allocator_Final_List): Test for an anonymous access type that is a
11708 function result type, and use the finalization list associated with the
11709 function scope in that case (such an anonymous type should not be
11710 treated like an access parameter's type).
11712 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11713 Gary Dismukes <dismukes@adacore.com>
11714 Javier Miranda <miranda@adacore.com>
11716 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
11717 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
11718 required exception handler.
11719 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
11720 properly the case of a function whose return type is a limited
11721 class-wide interface type. Modify the code of the accessibility
11722 check to handle class-wide interface objects. In this case we need to
11723 displace "this" to reference the primary dispatch table to get access
11724 to the TSD of the object (to evaluate its accessibility level).
11725 (Expand_N_Extended_Return_Statement): Test for a tagged result type
11726 rather than a controlling result as one of the conditions for
11727 generating tests of the implicit BIP_Alloc_Form formal. The
11728 initialization assignment is also handled according to whether the
11729 result is tagged instead of controlling.
11730 In the case where the init assignment is inserted in the "then" part of
11731 the allocation conditional, rewrite the target to be a dereference of
11732 the implicit BIP_Object_Access formal.
11733 If the returned value is unconstrained and created on the secondary
11734 stack, mark the enclosing block and function so that the secondary
11735 stack is not reclaimed on return.
11736 Treat returns from functions with controlling results similarly to
11737 returns from functions with unconstrained result subtypes.
11738 If the object returned is unconstrained, and an allocator must be
11739 created for it, analyze the allocator once the block for the extended
11740 return is installed, to ensure that finalizable components
11741 of the expression use the proper finalization list. Guard the call to
11742 Move_Final_List with a check that there is something to finalize.
11743 (Make_Tag_Ctrl_Assignment): Use "old" handling
11744 of controlled type assignment for virtual machines, since new code uses
11745 unsupported features (such as direct access to bytes in memory).
11747 2007-06-06 Gary Dismukes <dismukes@adacore.com>
11748 Ed Schonberg <schonberg@adacore.com>
11750 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
11751 accessibility actual, check for the case of an aliased object that has
11752 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
11753 we fall into processing for the attribute rather than the name of the
11755 (Expand_Inline_Call): If an actual is a literal, and the corresponding
11756 formal has its address taken in the body, create a temporary to capture
11757 value. If the return type is a limited interface, do not treat the
11758 return value as Controlled.
11759 (Is_In_Place_Function): If the return type is a limited interface,
11760 treat as returning in place. The actual returned object may not always
11761 be limited, but the caller has to assume that it is returned in place.
11762 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
11763 context of an allocator, use the correct finalization chain (that is,
11764 the chain belonging to the access type, rather than the chain belonging
11765 to the current scope).
11766 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
11767 result type rather than a controlling result as a precondition for
11768 adding an allocation form actual to a build-in-place call.
11769 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
11770 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
11771 primitive in the dispatch tables. This work is now done by Make_DT when
11772 the type is frozen.
11773 (Register_Predefined_DT_Entry): Removed.
11774 (Add_Return): If end label is not present, use sloc of last statement
11775 for generated return statement in procedure, for better gdb behavior
11777 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
11778 object address nodes to ensure proper processing by routines like
11780 (Expand_Call): Fix generation of validity check for parameter
11781 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
11782 the allocation form parameter if the result subtype is constrained,
11783 except when the function has a controlling result.
11784 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
11785 rather than Is_Controlled and Has_Controlled_Component, since we want to
11786 include class-wide result types in this treatment. Also test for a
11787 controlling result, since that also requires passing a finalization
11789 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
11790 even when the result subtype is constrained, to handle calls involving
11791 controlling results.
11792 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
11793 is now called even when the result subtype is constrained, to handle
11794 calls involving controlling results.
11795 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
11796 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
11797 now performs the test).
11798 (Make_Build_In_Place_Call_In_Object_Declaration):
11799 Add_Alloc_Form_Actual_* is now called even when the result subtype is
11800 constrained, to handle calls involving controlling results.
11801 (Add_Return): Accomodate rewritten pattern from local raise to goto
11802 transformation, so that we still recognize an transfer statement
11803 and do the right thing here in that case.
11804 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
11805 and end of subprogram code.
11806 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
11807 support for primitives that are functions (without formals) with a
11808 controlling result.
11809 (Inherited_From_Formal): If the actual subtype has not generic parent
11810 type, it is not an actual for a formal derived type, and there is no
11811 operation to inherit from the formal.
11813 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11814 Thomas Quinot <quinot@adacore.com>
11816 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
11817 inserted cleanup code appropriately for GDB use.
11818 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
11819 exception handler for Deep_Adjust or Deep_Finalize.
11820 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
11821 Raise_From_Controlled_Operation is available, use a call to that
11822 subprogram instead of a plain "raise Program_Error" node to raise
11823 Program_Error if an exception is propagated from an Adjust or Finalize
11825 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
11826 appears in the optional statement list of a triggering alternative, the
11827 scope actions can be inserted directly there, and not in the list that
11828 includes the asynchronous select itself.
11830 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11831 Robert Dewar <dewar@adacore.com>
11832 Hristian Kirtchev <kirtchev@adacore.com>
11834 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
11835 generated exception handler appropriately when debugging generated code.
11836 Deal properly with No_Exception_Propagation restriction mode.
11837 (Expand_N_Abort_Statement): Add an unchecked type conversion from
11838 System.Address to System.Tasking.Task_Id when processing the result of
11839 the predefined primitive _disp_get_task_id.
11840 (Expand_N_Asynchronous_Select): Clarify comment.
11841 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
11842 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
11843 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
11844 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
11845 privals and for generated call to Complete_Entry_Body, for better gdb
11847 (Copy_Result_Type): Utility to construct a parameter and result profile
11848 for protected functions whose return type is an anonymous access to

11859 functionality when the backend is generating code.
11860 Otherwise any serious error
11861 reported by the backend calling the frontend routine Error_Msg

12004 subtype from the function call, as is done for private types.
12005 (Side_Effect_Free): An expression that is the renaming of an object or
12006 whose prefix is the renaming of a object, is not side-effect free
12007 because it may be assigned through the renaming and its value must be

12532 associated with dispatch tables is known at compile time.
12533 (Get_Value): If an association in a record aggregate has a box
12534 association, and the corresponding record component has a default
12535 expression, always copy the default expression, even when the

13673 object of a null-excluding access type then don't require the
13674 the object declaration to have an expression and don't emit a

13737 (E_Return_Statement): This node type has the Finalization_Chain_Entity
13738 attribute, in case the result type has controlled parts.
13739 (Requires_Overriding): Add this new flag, because "requires
13740 overriding" is subtly different from "is abstract" (see AI-228).
13741 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
13742 Is_Abstract_Type. Make sure these are called only when appropriate.

13776 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
13777 stubbed procedure with a null body, replace the call with a null
13778 statement without using the full inlining machinery, for efficiency
13779 and to avoid invalid values in source file table entries.

13804 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
13805 "abstract subprograms must be visible" message, whether or not the type
13806 is an interface; that is, remove the special case for interface types.

13832 build-in-place functions with result type with controlled parts.
13833 Remove no longer used entities.
13835 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
13836 longer needed, because the full type is now limited, and therefore a

13838 (Foreign_Task_Level): New constant.
13840 * s-tassta.ads, s-tassta.adb (Move_Activation_Chain): New procedure to

13869 to handle properly the anonymous access case.
13871 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
13872 for all access attributes, because overload resolution should work the
13873 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This

13883 attempt to derive from a synchronized tagged type.
13884 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
13885 type, inherit the class-wide type already created, because it may
13886 already have been used in a self-referential anonymous access component.
13887 (Mentions_T): Recognize self-referential anonymous access components
13888 that use (a subtype of) the class-wide type of the enclosing type.
13889 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
13890 Derived_Type for Prev formal on call to
13891 Check_Anonymous_Access_Components rather than Empty.
13892 (Make_Incomplete_Type_Declaration): Add test for case where the type has
13893 a record extension in deciding whether to create a class-wide type,

13939 (Compile_Sources): Do nothing, not even check if the source is up to
13940 date, if its project is externally built.
13941 (Compile): When compiling a predefined source, add -gnatpg
13942 as the second switch, after -c.
13943 (Compile_Sources): Allow compilation of Annex J renames without -a
13944 (Is_In_Object_Directory): Check if the ALI file is in the object
13945 even if there is no project extension.

13947 gnatbind if the ALI file effectively exists.
13948 (Initialize): Add the directory where gnatmake is invoked in front of
13949 the path if it is invoked from a bin directory, even without directory

13974 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
13975 when -gnatg is not specified.
13976 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
13977 there is no need to generate always a record_definition_node in case
13978 of synchronized interface types.

14005 (Convert_Aggr_In_Allocator): If the allocator is for an access
14006 discriminant and the type is controlled. do not place on a finalization
14007 list at this point. The proper list will be determined from the

14026 succeed in that case, even when the expression originates from a
14027 parameter of the containing subprogram.
14028 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
14029 under No_Dispatching_Calls restriction. During the semantic analysis
14030 we already notified such violation.

14048 initialize most the TSD components by means of an aggregate.
14049 Modify the declaration of the object containing the TSD
14050 because we now expand code that has a higher level of abstraction.
14051 The TSD has a discriminant containing the Inheritance Depth Level,
14052 value that is used in the membership test but also to fix the size
14053 of the table of ancestors.
14054 (Expand_Interface_Conversion): Insert function body at the closest place
14055 to the conversion expression, to prevent access-before-elaboration

14095 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
14096 First (Parameter_Associations ()) with the call to First_Actual that
14097 returns an actual parameter expression for both named and positional
14100 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
14101 check violation of restriction No_Dispatching_Calls.
14102 (Check_Controlling_Type): A formal of a tagged incomplete type is a
14103 controlling argument.

14106 First/Next_Component_Or_Discriminant
14107 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
14108 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14109 specify Any_Limited_Interface, and this functionality is already
14110 provided by the function Has_Abstract_Interfaces.
14111 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
14112 support concurrent types implementing interfaces.
14113 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14114 specify kind Any_Limited_Interface, and this functionality is already

14131 Cyrille Comar <comar@adacore.com>
14133 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
14134 anonymous, use finalization list of enclosing dynamic scope.
14135 (Expand_N_Package_Declaration): For a library package declaration
14136 without a corresponding body, generate RACW subprogram bodies in the
14137 spec (just as we do for the task activation call).
14138 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
14139 Is_Abstract_Type. Make sure these are called only when appropriate.
14140 Remove all code for DSP option
14141 (CW_Or_Controlled_Type): new subprogram.
14143 2007-04-06 Eric Botcazou <botcazou@adacore.com>
14144 Ed Schonberg <schonberg@adacore.com>
14145 Gary Dismukes <dismukes@adacore.com>
14147 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
14148 parameter. If it is set to true, return a result capped according to
14149 the global upper bound for the index of an entry family.
14150 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
14151 (Build_Find_Body_Index): Adjust for above change.
14152 (Entry_Index_Expression): Likewise.
14153 (Is_Potentially_Large_Family): New function extracted from...
14154 (Collect_Entry_Families): ...here. Call it to detect whether the family
14155 is potentially large.
14156 (Build_Entry_Count_Expression): If the family is potentially large, call
14157 Family_Size with 'Cap' set to true.
14158 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
14159 a protected version of an operation declared in the private part of
14160 a protected object, because they may be invoked through a callback.
14161 (Set_Privals): If the type of a private component is an anonymous access
14162 type, do not create a new itype for each protected body.
14163 If the body of a protected operation creates
14164 controlled types (including allocators for class-widetypes), the
14165 body of the corresponding protected subprogram must include a
14167 (Build_Activation_Chain_Entity): Build the chain entity for extended
14169 (Type_Conformant_Parameters): Use common predicate Conforming_Types
14170 to determine whether operation overrides an inherited primitive.
14171 (Build_Wrapper_Spec): Add code to examine the parents while looking
14172 for a possible overriding candidate.
14173 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
14174 hold an actual parameter value since its initialization is separated
14175 from the the declaration. Prevents errors on null-excluding access
14178 2007-04-06 Thomas Quinot <quinot@adacore.com>
14179 Pablo Oliveira <oliveira@adacore.com>
14181 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
14182 Do an Unchecked_Conversion to handle the passage from the Underlying
14183 Type to the Base Type when calling Build_To_Any_Call and
14184 Build_From_Any_Call.
14185 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
14186 E_Constant, depending upon Variable formal.
14187 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14188 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
14189 parameter that requires an extra constrained parameter, declare
14190 temporary for actual as a variable, not a constant.
14191 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
14192 the unit being compiled is the one that contains the stub type.
14193 Change primitive operation name for the RACW associated with a RAS
14194 from Call to _Call so it cannot clash with any legal identifier.
14195 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
14197 (Append_RACW_Bodies): New subprogram.
14198 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
14199 Add_Receiving_Stubs_To_Declarations functions.
14200 When expanding a package body, this list correspond to the
14201 statements in the HSS at the end of the pacakge.
14202 When expanding a package spec, this list correspond to the
14204 (Add_Receiving_Stubs_To_Declarations): Append the function
14205 registering the receiving stubs at the end of the 'Stmts' list.
14206 (RCI_Package_Locator): Pass the new Version generic formal when
14207 instantiating a RCI_Locator package.
14208 (Build_From_Any_Function): To compute the High bound for an
14209 unconstrained array actual, we add the Low bound with the length.
14210 Thus we must convert the low bound and the length to an appropriate
14211 type before doing the sum.
14212 (Build_Subprogram_Receiving_Stubs, PolyORB):
14213 * Retrieve the extra formals parameters at the
14214 end of the parameter stream.
14215 * Use Move_Any_Value to write back out parameters
14216 after executing the request as it is more efficient
14217 than Copy_Any_Value.
14218 * Build the any containing Extra Formals with the
14219 appropriate typecode.
14220 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
14221 empty Component_List.
14222 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
14223 the tree the declaration for an object that serves as actual parameter
14224 in server-side stubs.
14225 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14226 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14227 Use Build_Actual_Object_Declaration to prepare the actuals.

14234 function with the first not implicit parent type.
14235 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
14236 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
14237 typecode from the Etype. Therefore we retrieve the correct typecode
14238 with a call to Get_Any_Type.
14239 (Copy_Specification): Do controlling formal type substitution based on
14240 Is_Controlling_Formal flag, instead of caller-provided object type.
14241 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
14242 a RACW primitive operation, we might get a subprogram declaration for an
14243 ancestor of the RACW designated type (not for the designated type
14244 itself), in the case where this operation is inherited. In this case we
14245 have no easy means of determining the original tagged type for which
14246 the primitive was declared, so instead we now rely on
14247 Copy_Specification to use the Is_Controlling_Formal flag to determine
14248 which formals require type substitution.

14256 handler unsuitable as a target for a local raise statement.
14257 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
14258 run-time subprogram CW_Membership by call to Build_CW_Membership.
14259 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
14260 by a function call, a temporary must be created before expanding the
14261 Constructor_Call itself, to prevent out-of-order elaboration in the
14262 back-end when stack checking is enabled..
14264 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14266 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
14267 result are the bounds of the left operand, not the right.
14269 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14272 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

14389 * mingw32.h (S2WSU): New macro to convert from a string to a
14390 wide-string using the UTF-8 encoding. The S2WS macro supports now only
14391 standard 8bits encoding.
14392 (WS2SU): As above but converting from wide-sring to string.
14393 This is needed as it is necessary to have access to both versions in the
14394 runtime for the form parameter encoding support.
14395 This set of patch add support for the encoding form parameter.
14396 (S2WS): Improve implementation to handle cases where the filename is not
14397 UTF-8 encoded. In this case we default to using the current code page
14398 for the conversion.
14400 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
14401 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

14445 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
14446 __gnat_adjust_context_for_raise.
14447 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
14448 implementation of floating point operations as native x86 targets.
14449 So the FPU should be initialized in the same way using finit. Fix
14450 floating point operations accuracy issues.
14451 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
14452 member in struct sigaction, so as to avoid warning for incompatible

14470 * lib-xref.ads, lib-xref.adb:
14471 Modify the loop that collects type references, to include interface
14472 types that the type implements. List each of these interfaces when
14473 building the entry for the type.
14474 (Generate_Definition): Initialize component Def and Typ of new entry
14475 in table Xrefs, to avoid to have these components unitialized.

14519 2007-04-06 Robert Dewar <dewar@adacore.com>
14521 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
14522 it no longer destroys the contents of Name_Buffer or Name_Len and
14523 non-standard and invalid names are handled better.
14524 (Get_Decoded_Name_String): Improve performance by using
14525 Name_Has_No_Encodings flag in the name table.
14526 (Is_Valid_Name): New function to determine whether a Name_Id is valid.

14536 of synchronized interface types.
14537 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
14538 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
14539 illegal in Ada 95, in cases where it is legal. Change the warnings to
14540 errors in other cases. Don't give the error unless the "not null"
14541 parses properly. Correct the source position at which the error occurs.
14542 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
14543 P_Null_Exclusion, to suppress "not null" warnings.

14619 the default project path, initially done during elaboration of the
14621 If the prefix returned by Sdefault is null, get the prefix from a call
14622 to Executable_Prefix_Path.
14623 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
14626 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
14627 canonical directory name to open the directory from which files are
14629 (Record_Other_Sources): Idem.
14630 (Locate_Directory): Add the possibility to create automatically missing
14631 directories when Setup_Projects is True.

14634 library source copy dir and exec dir.
14636 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
14639 2007-04-06 Robert Dewar <dewar@adacore.com>

14674 full word is no longer compared twice.
14676 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14678 * sem_ch10.adb (Install_Limited_Context_Clauses.
14679 Expand_Limited_With_Clause): Use a new copy of selector name in the
14680 call to Make_With_Clause. This fixes the tree structure for ASIS
14681 purposes. Nothing is changed in the compiler behaviour.
14682 (Process_Body_Clauses): Handle properly use clauses whose prefix is
14683 a package renaming.
14684 (Install_Limited_With_Clauses): Do not install non-limited view when it
14685 is still incomplete.

14688 Gary Dismukes <dismukes@adacore.com>
14690 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
14691 when capturing size information, instead of base type, which for a
14692 formal array type will be the unconstrained type.
14693 (Analyze_Formal_Object_Declaration): Add check for illegal default
14694 expressions for a formal in object of a limited type.
14695 (Instantiate_Object): Ditto.
14696 (Check_Formal_Package_Instance): Skip entities that are formal objects,
14697 because they were defaulted in the formal package and no check applies
14699 (Check_Formal_Package_Instance): Extend conformance check to other
14700 discrete types beyond Integer.
14701 (Process_Default): Copy directly the unmatched formal. A generic copy
14702 has already been performed in Analyze_Formal_Package.
14703 (Analyze_Associations): If a formal subprogram has no match, check for
14704 partial parametrization before looking for a default, to prevent
14706 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
14707 not set the instantiation environment before analyzing the actuals.
14708 Fixes regression on 8515-003 with implementation of AI-133.
14709 Set_Instance_Env checks whether the generic unit is a predefined
14710 unit, in which case the instance must be analyzed with the latest Ada
14711 mode. This setting must take place after analysis of the actuals,
14712 because the actuals must be analyzed and frozen in the Ada mode extant
14713 outside of the current instantiation.
14714 (Save_Env, Restore_Env): Preserve and restore the configuration
14715 parameters so that predefined units can be compiled in the proper Ada
14717 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
14718 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
14719 and Is_Abstract_Type.
14720 (Analyze_Formal_Package): For better error recovery, Add exception
14721 handler to catch Instantion_Error, which can be raised in
14722 Analyze_Associations

14725 Bob Duff <duff@adacore.com>
14726 Gary Dismukes <dismukes@adacore.com>
14728 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
14729 prefix type is a discriminated subtype of the type of the formal.
14730 (Analyze_Allocator): Collect all coextensions regardless of the context.
14731 Whether they can be allocated statically is determined in exp_ch4.
14732 (Analyze_Selected_Component): If the prefix is a limited view and the
14733 non-limited view is available, use the non-limited one.
14734 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
14735 therefore illegal), suggest a qualified expression rather than a type
14736 conversion, because a type conversion would be illegal in this context.
14737 (Anayze_Allocator): Trace recursively all nested allocators so that all
14738 coextensions are on the corresponding list for the root. Do no mark
14739 coextensions if the root allocator is within a declaration for a stack-
14740 allocated object, because the access discriminants will be allocated on
14742 (Analyze_Call): Remove restriction on calls to limited functions for the
14743 cases of generic actuals for formal objects, defaults for formal objects
14744 and defaults for record components.
14745 (Analyze_Allocator): Before analysis, chain coextensions on the proper
14746 element list. Their expansion is delayed until the enclosing allocator
14747 is processed and its finalization list constructed.
14748 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
14749 for an operation with the given name among the primitive operations of
14750 the corresponding record type.
14751 (Analyze_Selected_Component): If the prefix is a task type that
14752 implements an interface, and there is no entry with the given name,
14753 check whether there is another primitive operation (e.g. a function)
14755 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
14756 properly the indexing of a function call written in prefix form, where
14757 the function returns an array type, and all parameters of the function
14758 except the first have defaults.
14759 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
14760 the original operands, rather than relocating them, for efficiency and
14761 to work properly when an operand is overloaded.
14762 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
14763 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
14764 (Analyze_Selected_Component): If the prefix is a private extension, only
14765 scan the visible components, not those of the full view.
14766 (Try_Primitive_Operation): If the operation is a procedure, collect all
14767 possible interpretations, as for a function, because in the presence of
14768 classwide parameters several primitive operations of the type can match
14769 the given arguments.
14771 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14772 Robert Dewar <dewar@adacore.com>
14774 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
14775 tag-indeterminate call to an abstract function, when the left-hand side
14777 (Analyze_Loop_Statement): Improve detection of infinite loops
14779 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14780 Thomas Quinot <quinot@adacore.com>
14782 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
14783 out of Analyze_Package_Declaration, because processing must be applied
14784 to package bodies as well, for deferred constants completed by pragmas.
14785 (Analyze_Package_Declaration): When the package declaration being
14786 analyzed does not require an explicit body, call Check_Completion.
14787 (May_Need_Implicit_Body): An implicit body is required when a package
14788 spec contains the declaration of a remote access-to-classwide type.
14789 (Analyze_Package_Body): If the package contains RACWs, append the
14790 pending subprogram bodies generated by exp_dist at the end of the body.
14791 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
14792 Is_Abstract_Subprogram and Is_Abstract_Type.
14793 (Preserve_Full_Attributes): The full entity list is not an attribute
14794 that must be preserved from full to partial view.
14796 * sem_dist.adb (Add_RAS_Dereference_TSS):
14797 Change primitive name to _Call so it cannot clash with any legal
14798 identifier, and be special-cased in Check_Completion.
14799 Mark the full view of the designated type for the RACW associated with
14800 a RAS as Comes_From_Source to get proper view switching when installing
14801 private declarations.
14802 Provite a placeholder nested package body along with the nested spec
14803 to have a place for Append_RACW_Bodies to generate the calling stubs
14804 and stream attributes.
14806 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14807 Robert Dewar <dewar@adacore.com>
14809 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
14810 that is a limited view, check the non-limited view if available.
14811 (Undefined): Refine error message for missing with of Text_IO
14812 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
14813 to distinguish real missing with cases.
14814 Fix format of all missing with messages
14815 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
14816 renaming as body when renamed entity is abstract.
14818 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14819 Javier Miranda <miranda@adacore.com>
14821 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make

14831 Javier Miranda <miranda@adacore.com>
14833 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
14834 dereference of a local object R created as a reference to another
14835 object O, use the access level of O.
14836 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
14837 rather than local Same_Formal_Type, to check whether protected operation
14838 overrides an inherited one.
14839 (Same_Formal_Type): New predicate, used when matching signatures of
14840 overriding synchronized operations, to handle the case when a formal
14841 has a type that is a generic actual.
14842 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
14843 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
14844 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
14845 syntactic ambiguities involving indexing of function calls that return
14847 (Abstract_Interface_List): New subprogram that returns the list of
14848 abstract interfaces associated with a concurrent type or a
14849 concurrent record type.
14850 (Interface_Present_In_Parent): New subprogram used to check if a
14851 given type or some of its parents implement a given interface.
14852 (Collect_Abstract_Interfaces): Add support for concurrent types
14853 with interface types.
14854 (Has_Abstract_Interfaces): Add support for concurrent types with
14856 (Is_Parent): New subprogram that determines whether E1 is a parent
14857 of E2. For a concurrent type its parent is the first element of its
14858 list of interface types; for other types this function provides the
14859 same result than Is_Ancestor.
14860 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
14861 (Collect_Synchronized_Interfaces): Removed because the subprogram
14862 Collect_Abstract_Interfaces provides this functionality.
14863 (Collect_Abstract_Interfaces): Minor update to give support to
14864 concurrent types and thus avoid undesired code duplication.
14865 (Get_Subprogram_Entity): Handle entry calls.
14866 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
14868 (Enter_Name): Do not give -gnatwh hiding warning for record component

14884 can be an E_Return_Statement.
14885 (Is_Coextension): New flag for allocators.

14904 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
14905 expression with a COMPOUND_EXPR including the call instead of emitting
14906 the call directly here.
14907 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
14908 high bound is constant and the slice is empty. Tidy.
14909 (tree_transform, case N_Op_Not): Handle properly the case where the
14910 operation applies to a private type whose full view is a modular type.
14911 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
14912 Address_Clause, use the associated Expression as the GNAT tree
14913 representing the choice value to ensure the corresponding GCC tree is
14914 of the proper kind.
14915 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
14916 instead of just the operands, as the base GCC stabilize_reference does.
14917 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
14918 requested; otherwise fail.
14919 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

14924 implementation of UI_Div.
14925 (UI_Div): Reimplement as a call to UI_Div_Rem.
14926 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
14927 remainder, avoiding the cost of a multiplication and a subtraction.
14928 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
14929 provides both quotient and remainder in a single computation.
14930 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
14931 functions for uint.
14932 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
14933 is undefined if the given n is not inversible.
14935 2007-04-06 Olivier Hainque <hainque@adacore.com>
14937 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
14938 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion

14942 Olivier Hainque <hainque@adacore.com>
14944 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
14945 when updating the contents of the old pointer to an unconstrained array.
14946 (end_subprog_body): Set error_gnat_node to Empty.
14947 (write_record_type_debug_info): Do not be unduly sparing with our bytes.

15198 Valid_Conversion, to incorporate accessibility checks for arrays of
15199 anonymous access types.
15200 (Valid_Conversion): For a conversion to a numeric type occurring in an
15201 instance or inlined body, no need to check that the operand type is
15202 numeric, since this has been checked during analysis of the template.

15904 Ed Schonberg <schonberg@adacore.com>
15906 * exp_aggr.adb (Build_Record_Aggr_Code): For extension aggregates, if
15907 the parent part is a build-in-place function call, generate assignments.
15908 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
15909 are build-in-place function calls.
15910 (Replace_Self_Reference): New subsidiary of
15911 Make_OK_Assignment_Statement, to replace an access attribute that is a
15912 self-reference into an access to the appropriate component of the
15913 target object. Generalizes previous mechanism to handle self-references
15914 nested at any level.
15915 (Is_Self_Referential_Init): Remove, not needed.
15916 (Is_Self_Referential_Init): New predicate to simplify handling of self
15917 referential components in record aggregates.
15918 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
15919 check for presence of entity before checking for self-reference.
15920 (Has_Default_Init_Comps): Return True if a component association is a
15921 self-reference to the enclosing type, which can only come from a
15922 default initialization.
15923 (Make_OK_Assignment_Statement): If the expression is of the form
15924 Typ'Acc, where Acc is an access attribute, the expression comes from a
15925 default initialized self-referential component.
15926 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
15927 that has been derived from several abstract interfaces we must also
15928 initialize the tags of the secondary dispatch tables.
15930 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15931 Thomas Quinot <quinot@adacore.com>
15932 Javier Miranda <miranda@adacore.com>
15933 Robert Dewar <dewar@adacore.com>
15936 (Expand_Access_To_Protected_Op): If the context indicates that an access
15937 to a local operation may be transfered outside of the object, create an
15938 access to the wrapper operation that must be used in an external call.
15939 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
15940 target, pass the Valid attribute applied to a floating-point prefix on
15941 to the back end without expansion.
15942 (Storage_Size): Use the new run-time function Storage_Size to retrieve
15943 the allocated storage when it is specified by a per-object expression.
15944 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
15945 Nothing to do here, the attribute has been rewritten during semantic
15947 (Expand_Attribute_Reference): Handle expansion of the new Priority
15949 (Find_Fat_Info): Handle case of universal real
15950 (Expand_Access_To_Protected_Op): Fix use of access to protected
15951 subprogram from inside the body of a protected entry.
15952 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
15953 'Access and 'Unrestricted_Access, to transform the attribute reference
15954 into a fat pointer.
15955 (Is_Constrained_Aliased_View): New predicate to help determine whether a
15956 subcomponent's enclosing variable is aliased with a constrained subtype.
15957 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
15958 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
15959 an aliased prefix must be known to be constrained in order to use True
15960 for the attribute value, and now it's possible for some aliased views
15961 to be unconstrained.
15963 2006-10-31 Robert Dewar <dewar@adacore.com>
15965 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
15966 (Expand_Entity_Reference): Correct error of not handling subprogram
15967 formals in current_value processing.
15969 2006-10-31 Javier Miranda <miranda@adacore.com>
15970 Robert Dewar <dewar@adacore.com>
15971 Ed Schonberg <schonberg@adacore.com>
15972 Gary Dismukes <dismukes@adacore.com>
15974 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
15975 register in the final list objects containing class-wide interfaces;
15976 otherwise we incorrectly register the tag of the interface in the final
15978 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
15979 generate the wrapper if the parent primitive is abstract. This is
15980 required to report the correct error message.
15981 (Expand_N_Subtype_Indication): Do validity checks on range
15982 (Clean_Task_Names): If an initialization procedure includes a call to
15983 initialize a task (sub)component, indicate that the procedure will use
15984 the secondary stack.
15985 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
15986 compatibility for interfacing with CPP by default.
15987 (Expand_N_Object_Declaration): Only build an Adjust call when the
15988 object's type is a nonlimited controlled type.
15989 * exp_ch3.adb: Add with and use of Exp_Ch6.
15990 (Expand_N_Object_Declaration): Check for object initialization that is a
15991 call to build-in-place function and apply Make_Build_In_Place_Call_In_
15992 Object_Declaration to the call.
15993 (Freeze_Type): When the designated type of an RACW was not frozen at the
15994 point where the RACW was declared, validate the primitive operations
15995 with respect to E.2.2(14) when it finally is frozen.
15996 (Build_Initialization_Call,Expand_Record_Controller): Rename
15997 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
15998 return-by-reference has no meaning in Ada 2005.
15999 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
16000 to register tag of the immediate ancestor interfaces in the
16001 run-time structure.
16002 (Init_Secondary_Tags): Moved to the specification to allow the
16003 initialization of extension aggregates with abstract interfaces.
16004 (Build_Master_Renaming): Make public, for use by function declarations
16005 whose return type is an anonymous access type.
16006 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
16007 Insert_List_Before_And_Analyze after the generation of the specs
16008 associated with null procedures.
16009 (Expand_Tagged_Root): Update documentation in its specification.
16010 (Init_Secondary_Tags): Update documentation.
16011 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
16012 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
16013 then generate code to inherit the contents of the dispatch table
16014 directly from the ancestor.
16015 (Expand_Record_Controller): Insert controller component after tags of
16016 implemented interfaces.
16017 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
16018 create null procedure overridings when null procedures are inherited
16020 (Make_Null_Procedure_Specs): New procedure to generate null procedure
16021 declarations for overriding null primitives inherited from interfaces.
16022 (Is_Null_Interface_Procedure): New function in
16023 Make_Null_Procedure_Specs.
16024 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
16025 immediate ancestor of a tagged type is an abstract interface type we
16026 must generate the specification of the predefined primitives associated
16027 with controlled types (because the dispatch table of the ancestor is
16028 null and hence these entries cannot be inherited). This is required to
16029 elaborate well the dispatch table.

16037 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
16039 (Expand_N_In): Do validity checks on range
16040 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
16041 (Expand_N_Allocator): For "new T", if the object is constrained by
16042 discriminant defaults, allocate the right amount of memory, rather than
16043 the maximum for type T.
16044 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
16045 when the allocator is initialized by a build-in-place call, since the
16046 allocator is already rewritten as a reference to the function result,
16047 and this prevents an unwanted duplication of the function call.
16048 Add with and use of Exp_Ch6.
16049 (Expand_Allocator_Expresssion): Check for an allocator whose expression
16050 is a call to build-in-place function and apply
16051 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
16052 untagged designated types).
16053 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
16054 optimization if source or target is biased.
16055 (Expand_N_Allocator): Add comments for case of an allocator within a
16056 function that returns an anonymous access type designating tasks.
16057 (Expand_N_Allocator): apply discriminant checks for access
16058 discriminants of anonymous access types (AI-402, AI-416)

16061 Robert Dewar <dewar@adacore.com>
16062 Gary Dismukes <dismukes@adacore.com>
16063 Ed Schonberg <schonberg@adacore.com>
16065 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
16067 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
16068 (Expand_N_Assignment_Statement): Call
16069 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
16070 build-in-place function call. Currently, this can happen only for
16071 assignments that come from aggregates.
16072 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16073 in order to alleviate the upward compatibility introduced by AI-318.
16074 (Expand_N_Extended_Return_Statement): Add support for handling the
16075 return object as a build-in-place result.
16076 (Expand_Non_Function_Return): Implement simple return statements nested
16077 within an extended return.
16078 (Enable_New_Return_Processing): Turn on the new processing of return
16080 (Expand_Non_Function_Return): For a return within an extended return,
16081 don't raise Program_Error, because Sem_Ch6 now gives a warning.
16082 (Expand_N_Extended_Return_Statement): Implement AI-318
16083 (Expand_Simple_Function_Return): Ditto.
16084 (Expand_N_If_Statement): Handle new -gnatwt warning
16085 (Expand_N_Case_Statement): Handle new -gnatwt warning
16086 (Expand_N_Assignment): Handle assignment to the Priority attribute of
16087 a protected object.
16088 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
16089 validity checking of assignments to elementary record components.
16090 (Expand_N_Return_Statement): return Class Wide types on the secondary
16091 stack independantly of their controlled status since with HIE runtimes,
16092 class wide types are not potentially controlled anymore.
16094 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
16097 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
16098 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
16099 it expects a block, procedure, or task. The return statement will get
16100 turned into a block, and Expand_Cleanup_Actions will happen then.
16102 2006-10-31 Robert Dewar <dewar@adacore.com>
16103 Ed Schonberg <schonberg@adacore.com>
16104 Bob Duff <duff@adacore.com>
16105 Gary Dismukes <dismukes@adacore.com>
16107 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
16109 (Expand_Inlined_Call): Tagged types are by-reference types, and
16110 therefore should be replaced by a renaming declaration in the expanded
16111 body, as is done for limited types.
16112 (Expand_Call): If this is a call to a function with dispatching access
16113 result, propagate tag from context.
16114 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
16116 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
16117 build-in-place when the right-hand side of an assignment is a
16118 build-in-place function call.
16119 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
16120 of the explicit dereference of the allocator to the result subtype of
16121 the build-in-place function. This is needed to satisfy type checking
16122 in cases where the caller's return object is created by an allocator for
16123 a class-wide access type and the type named in the allocator is a
16125 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
16126 conversion of the reference to the declared object to the result subtype
16127 of the build-in-place function. This is needed to satisfy type checking
16128 in cases where the declared object has a class-wide type. Also, in the
16129 class-wide case, change the type of the object entity to the specific
16130 result subtype of the function, to avoid passing a class-wide object
16131 without explicit initialization to the back end.
16132 (Register_Interface_DT_Entry): Moved outside the body of
16133 Freeze_Subprogram because this routine is now public; it is called from
16134 Check_Dispatching_Overriding to handle late overriding of abstract
16135 interface primitives.
16136 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
16137 adding an implicit access actual on a call to a build-in-place function.
16138 (Expand_Actuals): Test for an actual parameter that is a call to a
16139 build-in-place function and apply
16140 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
16141 (Is_Build_In_Place_Function): New function to determine whether an
16142 entity is a function whose calls should be handled as build-in-place.
16143 (Is_Build_In_Place_Function_Call): New function to determine whether an
16144 expression is a function call that should handled as build-in-place.
16145 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
16146 calls to build-in-place functions as the initialization of an allocator.
16147 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
16148 handling calls to build-in-place functions in contexts that do not
16149 involve init of a separate object (for example, actuals of subprogram
16151 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
16152 handling calls to build-in-place functions as the initialization of an
16153 object declaration.
16154 (Detect_Infinite_Recursion): Add explicit parameter Process to
16155 instantiation of Traverse_Body to avoid unreferenced warning.
16156 (Check_Overriding_Inherited_Interfaces): Removed.
16157 (Register_Interface_DT_Entry): Code cleanup.
16158 (Register_Predefined_DT_Entry): Code cleanup.
16159 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
16160 inlined statements if within a transient scope.
16161 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
16162 formal parameters with occurrences of actuals in inlined body, establish
16163 visibility on the proper view of the actual's subtype for the body's
16165 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
16166 compatibility mode and we have an imported CPP subprogram because
16167 for now we assume that imported CPP primitives correspond with
16168 objects whose constructor is in the CPP side (and therefore we
16169 don't need to generate code to register them in the dispatch table).
16170 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
16171 aligned selected component.
16172 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
16173 the actual of an in-mode parameter is a type conversion.
16174 (Expand_Actuals): If the call does not come from source and the actual
16175 is potentially misaligned, let gigi handle it rather than rejecting the
16176 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
16177 Class Wide types as returning by reference independantly of their
16178 controlled status since with HIE runtimes class wide types are not
16179 potentially controlled anymore.
16181 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16183 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
16184 references that are private components of the protected object.
16185 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
16186 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
16187 instantiation to deal with warnings.
16188 (Initialize_Protection): If expression for priority is non-static, use
16189 System_Priority as its expected type, in case the expression has not
16192 2006-10-31 Robert Dewar <dewar@adacore.com>
16194 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
16195 initialization of Homonym_Len.
16196 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
16197 names from fully qualified name. Fixes problem of duplicate
16198 external names differing only in the presence of such a block name.
16200 2006-10-31 Thomas Quinot <quinot@adacore.com>
16201 Pablo Oliveira <oliveira@adacore.com>
16203 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
16204 subprogram Ids, even if they are not yet assigned.
16205 (Build_Subprogram_Id): It is now this function that will take care of
16206 calling Assign_Subprogram_Ids if necessary.
16207 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
16208 should be done only once they are assigned.
16209 (Build_From_Any_Function, case of tagged types): Add missing call to
16211 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
16212 type for an RACW type.
16213 (Add_RACW_Features): When processing an RACW declaration for which the
16214 designated type is already frozen, enforce E.2.2(14) rules immediately.
16215 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
16216 special reordering of controlling formals.
16218 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
16219 associated stub type for an RACW type.
16221 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16223 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
16224 fixed-point operations in an integer context, i.e. as operands of a
16225 conversion to an integer type, indicate that result must be rounded.
16227 2006-10-31 Robert Dewar <dewar@adacore.com>
16229 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
16230 cases, pass the encoding method, since it is now required by the run
16233 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
16234 assumption that Str'First = 1.
16235 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
16236 it on to the Value_Wide_Wide_Character call.
16237 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
16238 properly handles a string of the form quote-encoded_wide_char-quote.
16240 * s-wchcnv.adb: Minor reformatting
16242 2006-10-31 Javier Miranda <miranda@adacore.com>
16244 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
16245 run-time membership test to ensure that the constructed object
16246 implements the target abstract interface.
16248 2006-10-31 Robert Dewar <dewar@adacore.com>
16250 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
16251 Machine_Attribute pragma internally to implement the user pragma.
16252 Add processing for pragma Interface so that it is now completely
16253 equivalent to pragma Import.
16255 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
16256 so that it can be applied to all entities, including record components
16257 and enumeration literals.
16258 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
16259 priority ranges are correct, verify compatibility against task
16260 dispatching and locking policies, and if everything is correct an entry
16261 is added to the table containing priority specific dispatching entries
16262 for this compilation unit.
16263 (Delay_Config_Pragma_Analyze): Delay processing
16264 Priority_Specific_Dispatching pragmas because when processing the
16265 pragma we need to access run-time data, such as the range of
16266 System.Any_Priority.
16267 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
16268 Allow pragma Unreferenced as a context item
16269 Add pragma Preelaborable_Initialization
16270 (Analyze_Pragma, case Interface): Interface is extended so that it is
16271 now syntactically and semantically equivalent to Import.
16272 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
16273 insertion characters.
16274 Add handling for Pragma_Wide_Character_Encoding
16275 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
16276 never supercedes a real restriction, and that a real restriction
16277 always supercedes a warning.
16278 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

16283 Robert Dewar <dewar@adacore.com>
16285 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
16286 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
16287 Is_Inherently_Limited_Type, because return-by-reference has no meaning
16289 (Find_Node_To_Be_Wrapped): Use new method of determining the result
16290 type of the function containing a return statement, because the
16291 Return_Type field was removed. We now use the Return_Applies_To field.
16293 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
16294 (Build_Task_Image_Decl): If procedure is not called from an
16295 initialization procedure, indicate that function that builds task name
16296 uses the sec. stack. Otherwise the enclosing initialization procedure
16297 will carry the indication.
16298 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
16299 N_Object_Declaration instead.
16300 (Kill_Dead_Code): New interface to implement -gnatwt warning for
16301 conditional dead code killed, and change implementation accordingly.
16302 (Insert_Actions): Add N_Return_Object_Declaration case.
16303 Correct comment to mention N_Extension_Aggregate node.
16304 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
16305 attempts to save information for global variables which cannot be
16307 (Get_Current_Value_Condition): Handle conditions the other way round
16308 (constant on left). Also handle right operand of AND and AND THEN
16309 (Set_Current_Value_Condition): Corresponding changes
16310 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
16311 (Get_Current_Value_Condition): Handle simple boolean operands
16312 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
16313 (Get_Current_Value_Condition): If the variable reference is within an
16314 if-statement, does not appear in the list of then_statments, and does
16315 not come from source, treat it as being at unknown location.
16316 (Get_Current_Value_Condition): Enhance to allow while statements to be
16317 processed as well as if statements.
16318 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
16320 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
16321 of loop. This is safe now that we fixed Kill_Current_Values.
16322 (OK_To_Do_Constant_Replacement): Check whether current scope is
16323 Standard, before examining outer scopes.
16325 2006-10-31 Vincent Celier <celier@adacore.com>
16327 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
16328 When True, apply VMS treatment to children of packages A, G, I and S.
16331 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
16333 2006-10-31 Robert Dewar <dewar@adacore.com>
16334 Ed Schonberg <schonberg@adacore.com>
16336 * freeze.adb: Add handling of Last_Assignment field
16337 (Warn_Overlay): Supply missing continuation marks in error msgs
16338 (Freeze_Entity): Add check for Preelaborable_Initialization
16340 * g-comlin.adb: Add Warnings (Off) to prevent new warning
16342 * g-expect.adb: Add Warnings (Off) to prevent new warning
16344 * lib-xref.adb: Add handling of Last_Assignment field
16345 (Generate_Reference): Centralize handling of pragma Obsolescent here
16346 (Generate_Reference): Accept an implicit reference generated for a
16347 default in an instance.
16348 (Generate_Reference): Accept a reference for a node that is not in the
16349 main unit, if it is the generic body corresponding to an subprogram
16352 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
16354 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
16356 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
16358 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
16359 use clauses, to avoid messages on packages used to qualify, and also
16360 to avoid messages from obsolescent units.
16361 (Warn_On_Useless_Assignments): Don't generate messages for imported
16362 and exported variables.
16363 (Warn_On_Useless_Assignments): New procedure
16364 (Output_Obsolescent_Entity_Warnings): New procedure
16365 (Check_Code_Statement): New procedure
16367 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

16369 (Last_Assignment): New field for useless assignment warning
16371 2006-10-31 Olivier Hainque <hainque@adacore.com>
16373 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
16374 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
16376 2006-10-31 Bob Duff <duff@adacore.com>
16377 Robert Dewar <dewar@adacore.com>
16378 Ed Schonberg <schonberg@adacore.com>
16380 * g-awk.adb (Default_Session, Current_Session): Compile this file in
16381 Ada 95 mode, because it violates the new rules for AI-318.
16383 * g-awk.ads: Use overloaded subprograms in every case where we used to
16384 have a default of Current_Session. This makes the code closer to be
16385 correct for both Ada 95 and 2005.
16387 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
16388 code, relying on the fact that the compiler generates a warning
16389 instead of an error in -gnatg mode.
16391 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
16392 E_Return_Statement entity kind.
16393 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
16395 * par.adb (P_Interface_Type_Definition): Addition of one formal to
16396 report an error if the reserved word abstract has been previously found.
16397 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
16399 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
16400 parenthesized range attribute usage
16401 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
16403 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
16404 in the syntax for extended_return_statement. This is not in the latest
16405 RM, but the ARG is expected to issue an AI allowing this.
16406 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
16407 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
16408 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
16409 P_Return_Statement): Parse the new syntax for extended_return_statement.
16411 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
16412 Output_End_Missing): Add error-recovery code for the new
16413 extended_return_statement syntax; that is, the new E_Return entry on
16416 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
16417 limited to nonlimited, because otherwise we violate the new Ada 2005
16418 rules about returning limited types in function Create_AST_Handler in
16421 * sem.adb (Analyze): Add cases for new node kinds
16422 N_Extended_Return_Statement and N_Return_Object_Declaration.
16424 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
16425 type is in the same category as type of context before applying check,
16426 to prevent anomalies in instantiations.
16427 (Resolve_Aggregate): Remove test for limited components in aggregates.
16428 It's unnecessary in Ada 95, because if it has limited components, then
16429 it must be limited. It's wrong in Ada 2005, because limited aggregates
16431 (Resolve_Record_Aggregate): Move check for limited types later, because
16432 OK_For_Limited_Init requires its argument to have been resolved.
16433 (Get_Value): When copying the component default expression for a
16434 defaulted association in an aggregate, use the sloc of the aggregate
16435 and not that of the original expression, to prevent spurious
16436 elaboration errors, when the expression includes function calls.
16437 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
16438 were missing. We also didn't handle qualified expressions. Now also
16439 allow function calls. Use new common routine OK_For_Limited_Init.
16440 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
16441 with space can upper case letter).
16443 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
16444 Has_Static_Discriminants flag
16445 (Record_Type_Declaration): Diagnose an attempt to declare an interface
16446 type with discriminants.
16447 (Process_Range_Expr_In_Decl): Do validity checks on range
16448 (Build_Discriminant_Constraints): Use updated form of
16449 Denotes_Discriminant.
16450 (Process_Subtype): If the subtype is a private subtype whose full view
16451 is a concurrent subtype, introduce an itype reference to prevent scope
16453 (Build_Derived_Record_Type, Collect_Interface_Primitives,
16454 Record_Type_Declaration): The functionality of the subprograms
16455 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
16456 is now performed by a single routine.
16457 (Build_Derived_Record_Type): If the type definition includes an explicit
16458 indication of limitedness, then the type must be marked as limited here
16459 to ensure that any access discriminants will not be treated as having
16460 a local anonymous access type.
16461 (Check_Abstract_Overriding): Issue a detailed error message when an
16462 abstract subprogram was not overridden due to incorrect mode of its
16464 (Analyze_Private_Extension_Declaration): Add support for the analysis of
16465 synchronized private extension declarations. Verify that the ancestor is
16466 a limited or synchronized interface or in the generic case, the ancestor
16467 is a tagged limited type or synchronized interface and all progenitors
16468 are either limited or synchronized interfaces.
16469 Derived_Type_Declaration): Check for presence of private extension when
16470 dealing with synchronized formal derived types.
16471 Process_Full_View): Enchance the check done on the usage of "limited" by
16472 testing whether the private view is synchronized.
16473 Verify that a synchronized private view is completed by a protected or
16475 (OK_For_Limited_Init_In_05): New function.
16476 (Analyze_Object_Declaration): Move check for limited types later,
16477 because OK_For_Limited_Init requires its argument to have been resolved.
16478 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16479 in order to alleviate the upward compatibility introduced by AI-318.
16480 (Constrain_Corresponding_Record): If the constraint is for a component
16481 subtype, mark the itype as frozen, to avoid out-of-scope references to
16482 discriminants in the back-end.
16483 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
16484 this subprogram against wrong sources.
16485 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
16486 discriminant of limited type completed with a protected type, when the
16487 discriminant is used to constrain a private component of the type, and
16488 expansion is disabled.
16489 (Find_Type_Of_Object): Do not treat a return subtype that is an
16490 anonymous subtype as a local_anonymous_type, because its accessibility
16491 level is the return type of the enclosing function.
16492 (Check_Initialization): In -gnatg mode, turn the error "cannot
16493 initialize entities of limited type" into a warning.
16494 (OK_For_Limited_Init): Return true for generated nodes, since it
16495 sometimes violates the legality rules.
16496 (Make_Incomplete_Declaration): If the type for which an incomplete
16497 declaration is created happens to be the currently visible entity,
16498 preserve the homonym chain when removing it from visibility.
16499 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
16500 inherited subprograms.
16501 (Access_Definition): If this is an access to function that is the return
16502 type of an access_to_function definition, context is a type declaration
16503 and the scope of the anonymous type is the current one.
16504 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
16505 incomplete subtype to the set of private dependents of the original
16507 (Constrain_Discriminated_Type): Emit an error message whenever an
16508 incomplete subtype is being constrained.
16509 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
16510 corresponding subtype of the full view of the original incomplete type.
16511 (Check_Incomplete): Properly detect invalid usage of incomplete types
16514 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
16516 * g-catiio.ads, g-catiio.adb (Value): New function.

16525 Robert Dewar <dewar@adacore.com>
16527 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
16528 handling executable extension manually and duplicating code.
16530 * make.adb: Implement new -S switch
16531 (Gnatmake): Use new function Osint.Executable_Name instead
16532 of handling executable extension manually.
16534 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
16535 is specified, the executable name ends with this suffix.
16536 Take advantage of Osint.Executable_Name instead of duplicating code.
16538 * switch-m.adb: Recognize new gnatmake -S switch
16540 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
16542 (Get_Target_Parameters): Set Executable_Extension_On_Target if
16545 * makeusg.adb: Add line for gnatmake -S switch
16547 2006-10-31 Vincent Celier <celier@adacore.com>
16549 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
16550 call it with -static-libgcc, as there are some platforms, such as
16551 Darwin, where one of these two switches is compulsory to link.
16553 2006-10-31 Vincent Celier <celier@adacore.com>
16555 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
16556 instead of ADA_PROJECT_PATH, for the project path.
16557 (Gnatls): When displaying the project path directories, use host dir
16560 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
16561 names in the project path, as absolute paths may correspond to
16562 multi-valued VMS logical names.
16564 2006-10-31 Vincent Celier <celier@adacore.com>
16566 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
16567 absolute path name.
16568 (Locate_Regular_File): Ditto
16569 (Change_Dir): Remove, no longer used
16570 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
16571 on Windows. Get it calling Get_Current_Dir.
16572 (OpenVMS): Remove imported boolean, no longer needed.
16573 (Normalize_Pathname)[VMS]: Do not resolve directory names.
16574 (Pid_To_Integer): New function to convert a Process_Id to Integer
16576 2006-10-31 Thomas Quinot <quinot@adacore.com>
16578 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
16579 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
16581 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
16584 2006-10-31 Robert Dewar <dewar@adacore.com>

16591 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
16593 2006-10-31 Robert Dewar <dewar@adacore.com>
16595 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
16597 (Layout_Variant_Record): Retrieve the discriminants from the entity
16598 rather than from the type definition, because in the case of a full
16599 type for a private type we need to take the discriminants from the
16601 (Layout_Component_List): When applying the Max operator to variants with
16602 a nonstatic size, check whether either operand is static and scale that
16603 operand from bits to storage units before applying Max.
16604 (Layout_Type): In VMS, if a C-convention access type has no explicit
16605 size clause (and does not inherit one in the case of a derived type),
16606 then the size is reset to 32 from 64.
16608 2006-10-31 Vincent Celier <celier@adacore.com>
16610 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
16611 its file has already been loaded, according to the unit being loaded,
16612 not to the current value of Multiple_Unit_Index.
16614 2006-10-31 Thomas Quinot <quinot@adacore.com>
16615 Eric Botcazou <ebotcazou@adacore.com>

16627 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
16628 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
16629 Ada.Dispatching.Round_Robin.

16650 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16652 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
16653 Process_Body_Clauses): If the context of a body includes a use clause
16654 for P.Q then a with_clause for P in the same body is not redundant,
16655 even if the spec also has a with_clause on P.
16656 Add missing continuation mark to error msg
16657 (Build_Limited_Views): A limited view of a type is tagged if its
16658 declaration includes a record extension.
16659 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
16660 node, even if the subunit has errors. This avoids malfunction by
16661 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
16662 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
16663 generation of obsolescent messages for with statements (cannot do
16664 this too early, or we cannot implement avoiding the messages in the
16665 case of obsolescent units withing obsolescent units).
16666 (Install_Siblings): If the with_clause is on a remote descendant of
16667 an ancestor of the current compilation unit, find whether there is
16668 a sibling child unit that is immediately visible.
16669 (Remove_Private_With_Clauses): New procedure, invoked after completing
16670 the analysis of the private part of a nested package, to remove from
16671 visibility the private with_clauses of the enclosing package
16673 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
16674 now centralized in Generate_Reference.
16675 (Install_Limited_Context_Clauses): Remove superfluous error
16676 message associated with unlimited view visible through use
16677 and renamings. In addition, at the point in which the error
16678 is reported, we add the backslash to the text of the error
16679 to ensure that it is reported as a single error message.
16680 Use new // insertion for some continuation messages
16681 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
16682 to create implicit with_clause for parent unit mentioned in original
16683 limited_with_clause.
16684 (Install_Limited_With_Unit): Set entity of parent identifiers if the
16685 unit is a child unit. For ASIS queries.
16686 (Analyze_Subunit): If the subunit appears within a child unit, make all
16687 ancestor child units directly visible again.

16702 a formal object declaration with an access definition or a subtype mark
16703 with a null exclusion.
16704 (P_Generic_Association): Handle association with box, and others_choice
16705 with box, to support Ada 2005 partially parametrized formal packages.
16707 2006-10-31 Robert Dewar <dewar@adacore.com>
16708 Javier Miranda <miranda@adacore.com>
16710 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
16711 (P_Type_Declaration): Remove barrier against the reserved word "limited"
16712 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
16713 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
16714 private extensions.
16715 (P_Type_Declaration): Add the new actual Abstract_Present to every call
16716 to P_Interface_Type_Definition.
16717 (P_Interface_Type_Definition): Addition of one formal to report an error
16718 if the reserved word abstract has been previously found.
16719 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
16720 object renaming declaration with an access definition or subtype mark
16721 with a possible null exclusion.
16723 * par-ch9.adb: Minor error msg fix
16725 * par-load.adb: Add missing continuation mark to error msg

16740 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
16743 2006-10-31 Vincent Celier <celier@adacore.com>
16745 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
16746 on VMS, change "__" to '.' before checking the name.
16747 (Record_Ada_Source): Always add the source file name in the list of
16748 of sources, even if it is not the first time, as it is for another
16750 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
16751 dot, instead of replacing only the first '_'.
16753 * prj-part.adb (Parse): Convert project file path to canonical form
16755 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
16756 extended, the project id of the project extending it is recorded in its
16757 data, even when it has already been processed as an imported project.
16759 2006-10-31 Robert Dewar <dewar@adacore.com>
16761 * repinfo.adb (List_Entities): Don't list entities from renaming
16764 2006-10-31 Arnaud Charlet <charlet@adacore.com>
16765 Robert Dewar <dewar@adacore.com>
16767 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
16768 only a restriction warning is active for the given restriction. This is
16769 desirable because we do not want to modify code in the case where only
16771 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
16772 causes overriding of real restrictions.
16773 Take advantage of new No_Restrictions constant.
16775 * raise.h: (__gnat_set_globals): Change profile.
16777 2006-10-31 Arnaud Charlet <charlet@adacore.com>
16779 * rtsfind.adb: Remove s-polint from comment as it exists no more.

16800 Gary Dismukes <dismukes@adacore.com>
16802 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
16803 properly an attempt to apply Unchecked_Access to a protected operation.
16804 (OK_Self_Reference): New subprogram to check the legality of an access
16805 attribute whose prefix is the type of an enclosing aggregate.
16806 Generalizes previous mechanism to handle attribute references nested
16807 arbitrarily deep within the aggregate.
16808 (Analyze_Access_Attribute): An access attribute whose prefix is a type
16809 can appear in an aggregate if this is a default-initialized aggregate
16810 for a self-referential type.
16811 (Resolve_Attribute, case Access): Ditto.
16812 Add support for new implementation defined attribute Stub_Type.
16813 (Eval_Attribute, case Attribute_Stub_Type): New case.
16814 (Analyze_Attribute, case Attribute_Stub_Type): New case.
16815 (Stream_Attribute_Available): Implement using new subprogram from
16816 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
16817 Has_Specified_Stream_Attribute flag.
16818 Disallow Storage_Size and Storage_Pool for access to subprogram
16819 (Resolve_Attribute, case 'Access et al): Take into account anonymous
16820 access types of return subtypes in extended return statements. Remove
16821 accessibility checks on anonymous access types when Unchecked_Access is
16823 (Analyze_Attribute): Add support for the use of 'Class to convert
16824 a class-wide interface to a tagged type.
16825 Add support for the attribute Priority.
16826 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
16827 whether the designated type is discriminated with a constrained partial
16828 view and require static matching in that case.
16829 Add local variable Des_Btyp. The Designated_Type
16830 of an access to incomplete subtype is either its non-limited view if
16831 coming from a limited with or its etype if regular incomplete subtype.
16833 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
16834 Fix predicate to identify and allow cases of (expander-generated)
16835 references to tag of designated object of a RACW.
16836 (Validate_Static_Object_Name): In Ada 2005, a formal object is
16837 non-static, and therefore cannot appear as a primary in a preelaborable
16839 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
16840 Has_Read_Write_Attributes.
16841 (Has_Read_Write_Attributes): Reimplement in termes of
16842 Has_Stream_Attribute_Definition.
16843 (Missing_Read_Write_Attributes): When checking component types in a
16844 record, unconditionally call Missing_Read_Write_Attributes recursively
16845 (remove guard checking for Is_Record_Type / Is_Access_Type).
16847 2006-10-31 Robert Dewar <dewar@adacore.com>
16849 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
16850 useless assignments here and conditionalize it on absence of exception
16852 (Analyze_Exception_Handlers): Small code reorganization of error
16853 detection code, for new handling of formal packages.
16855 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16856 Hristian Kirtchev <kirtchev@adacore.com>
16858 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
16859 that has been constant-folded, preserve information of original tree,
16861 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
16862 generated private extension declaration if the formal derived type is
16863 synchronized. Carry synchronized present over to the generated private
16865 (Validate_Derived_Type_Instance): Ensure that the actual of a
16866 synchronized formal derived type is a synchronized tagged type.
16867 (Instantiate_Formal_Package): When creating the instantiation used to
16868 validate the actual package of a formal declared without a box, check
16869 whether the formal itself depends on a prior actual.
16870 (Instantiate_Formal_Subprogram): Create new entities for the defining
16871 identifiers of the formals in the renaming declaration, for ASIS use.
16872 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
16873 a renaming declaration or a subtype declaration for an actual in an
16874 instance, capture location information of declaration in generic, for
16876 (Instantiate_Formal_Package): Add comments on needed additional tests.
16877 AI-317 (partial parametrization) is fully implemented.
16878 (Validate_Private_Type_Instance): Add check for actual which
16879 must have preelaborable initialization
16880 Use new // insertion for some continuation messages
16881 (Analyze_Formal_Object_Declaration): Change usage of Expression to
16882 Default_Expression. Add type retrieval when the declaration has an
16883 access definition. Update premature usage of incomplete type check.
16884 (Check_Access_Definition): New subsidiary routine. Check whether the
16885 current compilation version is Ada 05 and the supplied node has an
16887 (Instantiate object): Alphabetize local variables. Handle the creation
16888 of new renaming declarations with respect to the kind of definition
16889 used - either an access definition or a subtype mark. Guard against
16890 unnecessary error message in the context of anonymous access types after
16891 they have been resolved. Add check for required null exclusion in a
16892 formal object declaration.
16893 (Switch_View): A private subtype of a non-private type needs to be
16894 switched (the base type can have been switched without its private
16895 dependents because of the last branch of Check_Private_View.
16896 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
16898 (Instantiate_Type): Emit an error message whenever a class-wide type of
16899 a tagged incomplete type is used as a generic actual.
16900 (Find_Actual_Type): Extend routine to handle a component type in a child
16901 unit that is imported from a formal package in a parent.
16902 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
16903 agree on constrainedness, rather than checking against ultimate ancestor
16904 (Instantiate_Subprogram_Body): Create a cross-reference link to the
16905 generic body, for navigation purposes.
16907 2006-10-31 Robert Dewar <dewar@adacore.com>
16908 Thomas Quinot <quinot@adacore.com>
16910 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
16912 (New_Stream_Subprogram): When processing an attribute definition clause
16913 for a stream-oriented subprogram, record an entity node occurring at
16914 the point of clause to use for checking the visibility of the clause,
16915 as defined by 8.3(23) as amended by AI-195.
16916 (New_Stream_Subprogram): New procedure, factoring behaviour from both
16917 New_Stream_Function and New_Stream_Procedure.
16918 (New_Stream_Function, New_Stream_Procedure): Removed.
16919 (Analyze_Attribute_Definition_Clause, case Address): Check new
16920 Alignment_Check check

16923 Javier Miranda <miranda@adacore.com>
16924 Robert Dewar <dewar@adacore.com>
16926 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
16927 generate the same errors compiling under -gnatc.
16928 (Try_Object_Operation): If no candidate interpretation succeeds, but
16929 there is at least one primitive operation with the right name, report
16930 error in call rather than on a malformed selected component.
16931 (Analyze_Selected_Component): If the prefix is an incomplete type from
16932 a limited view, and the full view is available, use the full view to
16933 determine whether this is a prefixed call to a primitive operation.
16934 (Operator_Check): Verify that a candidate interpretation is a binary
16935 operation before checking the type of its second formal.
16936 (Analyze_Call): Add additional warnings for function call contexts not
16938 (Analyze_Allocator): Move the check for "initialization not allowed for
16939 limited types" after analyzing the expression. This is necessary,
16940 because OK_For_Limited_Init looks at the structure of the expression.
16941 Before analysis, we don't necessarily know what sort of expression it
16942 is. For example, we don't know whether F(X) is a function call or an
16943 indexed component; the former is legal in Ada 2005; the latter is not.
16944 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
16945 were missing. We also didn't handle qualified expressions. Now also
16946 allow function calls. Use new common routine OK_For_Limited_Init.
16947 (Analyze_Type_Conversion): Do not perform some legality checks in an
16948 instance, because the error message will be redundant or spurious.
16949 (Analyze_Overloaded_Selected_Component): Do not do style check when
16950 setting an entity, since we do not know it is the right entity yet.
16951 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
16952 (Analyze_Overloaded_Selected_Component): Same change
16953 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
16954 since regular incomplete subtypes are transformed into corresponding
16955 subtypes of their full views.
16956 (Complete_Object_Operation): Treat name of transformed subprogram call
16957 as coming from source, for browsing purposes.
16958 (Try_Primitive_Operation): If formal is an access parameter, compare
16959 with base type of object to determine whether it is a primitive
16961 (Operator_Check): If no interpretation of the operator matches, check
16962 whether a use clause on any candidate might make the operation legal.
16963 (Try_Class_Wide_Operation): Check whether the first parameter is an
16964 access type whose designated type is class-wide.

16971 warn on infinite loops.
16972 Add \\ to some continuation messages
16973 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
16974 (Process_Bounds): If the bounds are integer literals that result from
16975 constant-folding, and they carry a user-defined type, preserve that type
16976 rather than treating this as an integer range.
16977 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
16978 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
16979 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
16980 left hand side of assignment.
16981 (Analyze_Assignment): Add suport to manage assigments to the attribute
16982 priority of a protected object.
16983 (Check_Possible_Current_Value_Condition): Allow fully qualified names
16984 not just identifiers.
16985 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
16986 or AND THEN for possible tracking.
16987 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
16988 case of while loops so we can track values in the loop body.

16991 Hristian Kirtchev <kirtchev@adacore.com>
16992 Bob Duff <duff@adacore.com>
16994 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
16995 procedure cannot be a protected operation (it is a basic_declaration,
16996 not a subprogram_declaration).
16997 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
16998 Subp. Add logic for entry processing.
16999 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
17000 Determine whether an entry or subprogram of a protected or task type
17001 override an inherited primitive of an implemented interface.
17002 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
17003 Update the actual used in calls to Check_Overriding_Indicator.
17004 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
17005 generate the proper reference to the parent unit, for cross-reference.
17006 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
17008 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17009 (Add_Extra_Formal): Revise procedure to allow passing in associated
17010 entity, scope, and name suffix, and handle setting of the new
17011 Extra_Formals field.
17012 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
17013 pass new parameters. Add support for adding the new extra access formal
17014 for functions whose calls are treated as build-in-place.
17015 (Analyze_A_Return_Statement): Correct casing in error message.
17016 Move Pop_Scope to after Analyze_Function_Return, because an extended
17017 return statement really is a full-fledged scope. Otherwise, visibility
17018 doesn't work right. Correct use of "\" for continuation messages.
17019 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
17020 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
17021 the node doesn't get properly marked as analyzed.
17022 (Analyze_Subprogram_Body): If subprogram is a function that returns
17023 an anonymous access type that denotes a task, build a Master Entity
17025 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
17026 proper usage of null exclusion in a result definition.
17027 (Process_Formals): Code cleanup and new error message.
17028 (Process_Formals): Detect incorrect application of null exclusion to
17030 (Conforming_Types): Handle conformance between [sub]types and itypes
17031 generated for entities that have null exclusions applied to them.
17032 (Maybe_Primitive_Operation): Add an additional type retrieval when the
17033 base type is an access subtype. This case arrises with null exclusions.
17034 (New_Overloaded_Entity): Do not remove the overriden entity from the
17035 homonym chain if it corresponds with an abstract interface primitive.
17036 (Process_Formals): Replace membership test agains Incomplete_Kind with a
17037 call to the synthesized predicate Is_Incomplete_Type.
17038 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
17040 (Analyze_Subprogram_Declaration): Check that abstract interface
17041 primitives are abstract or null.
17042 (Analyze_Subprogram_Specification): Remove previous check for abstract
17043 interfaces because it was not complete.
17044 (Has_Interface_Formals): Removed.

17047 Javier Miranda <miranda@adacore.com>
17049 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
17050 of Analyze_Package_Body, to create Itype references for anonymous
17051 access types created in the package declaration, whose designated types
17052 may have only a limited view.
17053 (Analyze_Package_Specification): For the private part of a nested
17054 package, install private_with_clauses of enclosing compilation unit if
17055 we are in its visible part.
17056 (Declare_Inherited_Private_Subprograms): Complete barrier
17057 to ensure that the primitive operation has an alias to some parent
17058 primitive. This is now required because, after the changes done for the
17059 implementation of abstract interfaces, the contents of the list of
17060 primitives has entities whose alias attribute references entities of
17061 such list of primitives.
17062 (Analyze_Package_Specification): Simplify code that handles parent units
17063 of instances and formal packages.
17064 (Uninstall_Declarations): Check the convention consistency among
17065 primitive overriding operations of a tagged record type.

17074 expected and found set right)
17075 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
17076 (Analyze_Generic_Renaming): Same fix
17077 (Use_One_Package): Do not take into account the internal entities of
17078 abstract interfaces during the analysis of entities that are marked
17079 as potentially use-visible.
17080 (Find_Type): Handle the case of an attribute reference for
17081 implementation defined attribute Stub_Type (simply let the analysis of
17082 the attribute reference rewrite it).
17083 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
17084 type that appears in a Use_Type clause.
17085 (Analyze_Object_Renaming): Add support for renaming of the Priority
17087 (Find_Type): In Ada 2005, a task type can be used within its own body,
17088 when it appears in an access definition.
17089 (Analyze_Object_Renaming): Remove warning on null_exclusion.
17090 (Analyze_Object_Renaming): Introduce checks for required null exclusion
17091 in a formal object declaration or in a subtype declaration.
17092 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
17093 (Check_Null_Exclusion): New local routine to
17094 Analyze_Subprogram_Renaming. Check whether the formals and return
17095 profile of a renamed subprogram have required null exclusions when
17096 their counterparts of the renaming already impose them.
17097 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
17098 Determine whether an entity is inside a generic scope.
17099 (In_Open_Scope): First pass of documentation update.
17100 (Find_Expanded_Name): Add support for shadow entities associated with
17101 limited withed packages. This is required to handle nested packages.
17102 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
17103 that makes a renaming of a limited withed package illegal.

17109 Check_Overriding_Indicator.
17110 (Analyze_Task_Definition): Ditto.
17111 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
17112 (Check_Overriding_Indicator): To find overridden interface operation,
17113 examine only homonyms that have an explicit subprogram declaration, not
17114 inherited operations created by an unrelated type derivation.
17115 (Check_Overriding_Indicator): When checking for the presence of "null"
17116 in a procedure, ensure that the queried node is a procedure

17119 type when the formal is an access to variable.
17120 (Analyze_Protected_Type): Add check for Preelaborable_Initialization

17131 inherited from an interface ancestor by another interface in the
17132 context of an instance as 'late'.

17134 of a call to a function that dispatches on access result.
17135 (Check_Dispatching_Operation): In case of late overriding of a primitive
17136 that covers abstract interface subprograms we register it in all the
17137 secondary dispatch tables associated with abstract interfaces.
17138 (Check_Dispatching_Call): Add check that a dispatching call is not made
17139 to a function with a controlling result of a limited type. This is a
17140 current implementation restriction.
17141 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
17142 (Check_Dispatching_Operation): Do no emit a warning if the controlling
17143 argument is an interface type that is a generic formal.
17144 (Is_Interface_Subprogram): Removed.
17145 (Check_Dispatching_Operation): If the subprogram is not a dispatching
17146 operation, check the formals to handle the case in which it is
17147 associated with an abstract interface type.

17167 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
17168 subprogram type to provide better diagnostics in case of ambiguity.
17169 (Covers): Handle coverage of formal and actual anonymous access types in
17170 the context of generic instantiation.
17171 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
17172 abstract interface types; this is required to handle concurrent types
17173 with discriminants and abstract interface types.
17174 (Covers): Include type coverage of both regular incomplete subtypes and
17175 incomplete subtypes of incomplete type visibles through a limited with

17187 Add missing continuation marks in error msgs
17188 (Unqualify): New function for removing zero or more levels of
17189 qualification from an expression. There are numerous places where this
17190 ought to be used, but we currently only deal properly with zero or one
17192 (In_Instance); The analysis of the actuals in the instantiation of a
17193 child unit is not within an instantiation, even though the parent
17194 instance is on the scope stack.
17195 (Safe_To_Capture_Value): Exclude the case of variables that are
17197 (Check_Obsolescent): Removed
17198 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

17211 Change Is_Lvalue to May_Be_Lvalue
17212 (May_Be_Lvalue): Extensive additional code to deal with subprogram
17213 arguments (IN parameters are not Lvalues, IN OUT parameters are).
17214 (Safe_To_Capture_Value): Extend functionality so it can be used for
17215 the current value condition case.
17216 (Has_Compatible_Alignment): New function
17217 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
17218 objects to handle the Ada 2005 case, where aliasedness no longer implies
17219 that the object is constrained. In particular, for dereferenced names,
17220 the designated object must be assumed to be unconstrained.
17221 (Kill_Current_Values): Properly deal with the case where we encounter
17222 a loop in the scope chain.
17223 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
17225 (Compile_Time_Constraint_Error): Improve error message in error case

17960 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
17961 abstract interface type, the static analysis is not enough to know if
17962 the interface is implemented or not by the source tagged type. Hence
17963 we must pass the work to the expander to generate the required code to
17964 evaluate the conversion at run-time.
17965 (Resolve_Equality_Op): Do not apply previous
17966 transformation if expansion is disasbled, to prevent anomalies when

18688 Olivier Hainque <hainque@adacore.com>
18690 * bindusg.adb: Updated documentation for -d and -D switches.
18692 * raise.h (__gnat_set_globals): added new parameter for
18693 Default_Stack_Size.
18695 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
18696 (__gnat_handle_vms_condition): Adjust context before raise.
18697 (__gnat_install_handler): Restore the global vector setup for GCC
18698 versions before 3.4, as the frame based circtuitry is not available
18700 (__gnat_set_globals): added a parameter default_stack_size
18701 (__gl_default_stack_size): new variable.
18703 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18705 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
18706 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
18707 does not exist in the Ada RM.
18708 (Compatible_Int_Bounds): Determine whether two integer range bounds
18709 are of equal length and have the same start and end values.
18710 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
18711 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
18712 aggregate when it is part of an object declaration.
18713 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
18714 constrains discriminants of its parent, add explicitly the discriminant
18715 constraints of the ancestor by retrieving them from the
18716 stored_constraint of the parent.
18718 2006-02-13 Robert Dewar <dewar@adacore.com>
18720 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
18721 attribute Mechanism_Code is applied to renamed subprogram, modify
18722 prefix to point to base subprogram.
18723 Max/Min attributes now violate Restriction No_Implicit_Conditionals
18725 * sinfo.ads: Document that Mechanism_Code cannot be applied to
18726 renamed subprograms so that the front-end must replace the prefix
18729 2006-02-13 Javier Miranda <miranda@adacore.com>
18730 Gary Dismukes <dismukes@adacore.com>
18732 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
18733 availability of RE_Interface_Tag.
18734 (Build_Initialization_Call): Fix wrong access to the discriminant value.
18735 (Freeze_Record_Type): Do not generate the tables associated with
18736 timed and conditional dispatching calls through synchronized
18737 interfaces if compiling under No_Dispatching_Calls restriction.
18738 When compiling for Ada 2005, for a nonabstract
18739 type with a null extension, call Make_Controlling_Function_Wrappers
18740 and insert the wrapper function declarations and bodies (the latter
18741 being appended as freeze actions).
18742 (Predefined_Primitive_Bodies): Do not generate the bodies of the
18743 predefined primitives associated with timed and conditional
18744 dispatching calls through synchronized interfaces if we are
18745 compiling under No_Dispatching_Calls.
18746 (Build_Init_Procedure): Use RTE_Available to check if a run-time
18747 service is available before generating a call.
18748 (Make_Controlling_Function_Wrappers): New procedure.
18749 (Expand_N_Full_Type_Declaration): Create a class-wide master for
18750 access-to-limited-interfaces because they can be used to reference
18751 tasks that implement such limited interface.
18752 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
18753 procedure spec and body of the Offset_To_Top function that is generated
18754 when the parent of a type with discriminants has secondary dispatch
18756 (Init_Secondary_Tags): Handle the case in which the parent of the type
18757 containing secondary dispatch tables has discriminants to generate the
18758 correct arguments to call Set_Offset_To_Top.
18759 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
18761 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
18762 Add Wide_[Wide_]Expanded_Name.
18763 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
18764 the same functionality of Get_Prim_Op_Address but applied to predefined
18765 primitive operations because the pointers to the predefined primitives
18766 are now saved in a separate table.
18767 (Parent_Size): Modified to get access to the separate table of primitive
18768 operations or the parent type.
18769 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
18770 functionality of Set_Prim_Op_Address but applied to predefined primitive
18772 (Set_Signature): New subprogram used to store the signature of a DT.
18773 (Displace): If the Offset_To_Top value is not static then call the
18774 function generated by the expander to get such value; otherwise use
18775 the value stored in the table of interfaces.
18776 (Offset_To_Top): The type of the actual has been changed to Address to
18777 give the correct support to tagged types with discriminants. In this
18778 case this value is stored just immediately after the tag field.
18779 (Set_Offset_To_Top): Two new formals have been added to indicate if the
18780 offset_to_top value is static and hence pass this value to the run-time
18781 to store it in the table of interfaces, or else if this value is dynamic
18782 and then pass to the run-time the address of a function that is
18783 generated by the expander to provide this value for each object of the
18786 * rtsfind.ads (Default_Prin_Op_Count): Removed.
18787 (Default_Prim_Op_Count): New entity
18788 (Get_Predefined_Prim_Op_Address): New entity
18789 (Set_Predefined_Prim_Op_Address): New entity
18790 (RE_Set_Signature): New entity
18792 2006-02-13 Thomas Quinot <quinot@adacore.com>
18793 Ed Schonberg <schonberg@adacore.com>
18795 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
18796 Make_Adjust_Call done for a newly-allocated object.
18798 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
18799 in a subprogram are wrapped in a cleanup block, indicate that the
18800 subprogram contains an inner block with an exception handler.
18801 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
18802 Adjust call is for a newly-allocated object. In that case we must not
18803 assume that the finalization list chain pointers are correct (since they
18804 come from a bit-for-bit copy of the original object's pointers) so if
18805 the attach level would otherwise be zero (no change), we set it to 4
18806 instead to cause the pointers to be reset to null.
18808 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
18809 reset chain pointers to null.
18811 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18813 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
18814 string, and the context requires a loop for the assignment (e.g.
18815 because the left-hand side is packed), generate a unique name for the
18816 temporary that holds the string, to prevent spurious name clashes.
18818 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18819 Javier Miranda <miranda@adacore.com>
18820 Robert Dewar <dewar@adacore.com>
18821 Gary Dismukes <dismukes@adacore.com>
18823 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
18824 return unconstrained arrays.
18826 (Expand_Call): An indirect call through an access parameter of a
18827 protected operation is not a protected call.
18828 Add circuit to raise CE in Ada 2005 mode following call
18829 to Raise_Exception.
18830 (Register_DT_Entry): Do nothing if
18831 the run-time does not give support to abstract interfaces.
18832 (Freeze_Subprogram): In case of dispatching operations, do not generate
18833 code to register the operation in the dispatch table if the source
18834 is compiled with No_Dispatching_Calls.
18835 (Register_Predefined_DT_Entry): Generate code that calls the new
18836 run-time subprogram Set_Predefined_Prim_Op_Address instead of
18837 Set_Prim_Op_Address.
18839 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
18840 on array assignments if the right-hand side is a function call that has
18841 been inlined. Check is performed on the assignment in the block.
18842 (Process_Bounds): If bounds and range are overloaded, apply preference
18843 rule for root operations to disambiguate, and diagnose true ambiguity.
18844 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
18845 a tag-indeterminate right-hand side even when Expander_Active is True.
18846 Needed to ensure that dispatching calls to T'Input are allowed and
18847 get the tag of the target class-wide object.
18849 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
18850 an inherited primitive operation that already overrides several
18851 abstract interface primitives. For transitivity, the new entity must
18852 also override all the abstract interface primitives covered by the
18853 inherited overriden primitive.
18854 Emit warning if new entity differs from homograph in same scope only in
18855 that one has an access parameter and the other one has a parameter of
18856 a general access type with the same designated type, at the same
18857 position in the signature.
18858 (Make_Inequality_Operator): Use source locations of parameters and
18859 subtype marks from corresponding equality operator when creating the
18860 tree structure for the implicit declaration of "/=". This does not
18861 change anything in behaviour except that the decoration of the
18862 components of the subtree created for "/=" allows ASIS to get the
18863 string images of the corresponding identifiers.
18864 (Analyze_Return_Statement): Remove '!' in warning message.
18865 (Check_Statement_Sequence): Likewise.
18866 (Analyze_Subprogram_Body): For an access parameter whose designated type
18867 is an incomplete type imported through a limited_with clause, use the
18868 type of the corresponding formal in the body.
18869 (Check_Returns): Implicit return in No_Return procedure now raises
18870 Program_Error with a compile time warning, instead of beging illegal.
18871 (Has_Single_Return): Function returning unconstrained type cannot be
18872 inlined if expression in unique return statement is not an identifier.
18873 (Build_Body_To_Inline): It is possible to inline a function call that
18874 returns an unconstrained type if all return statements in the function
18875 return the same local variable. Subsidiary procedure Has_Single_Return
18876 verifies that the body conforms to this restriction.
18878 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
18879 same type, and one of them is of an anonymous access type, convert
18880 the other operand to it, so that this is a valid binary operation for
18882 (Resolve_Type_Conversion): Handle subtypes of protected types and
18883 task types when accessing to the corresponding record type.
18884 (Resolve_Allocator): Add '\' in 2-line warning message.
18885 Remove '!' in warning message.
18886 (Resolve_Call): Add '\' in 2-line warning message.
18887 (Valid_Conversion): Likewise.
18888 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
18889 resulting type may be an access type with an implicit dereference.
18890 Obtain the proper component from the designated type.
18891 (Make_Call_Into_Operator): Handle properly a call to predefined equality
18892 given by an expanded name with prefix Standard, when the operands are
18893 of an anonymous access type.
18894 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
18895 Explicit_Dereference and Resolve_Selected_Component, to verify that the
18896 prefix of the expression is not of an incomplete type. Allows full
18897 diagnoses of all semantic errors.
18898 (Resolve_Actuals): If the actual is an allocator whose directly
18899 designated type is a class-wide interface we build an anonymous
18900 access type to use it as the type of the allocator. Later, when
18901 the subprogram call is expanded, if the interface has a secondary
18902 dispatch table the expander will add a type conversion to force
18903 the displacement of the pointer.
18904 (Resolve_Call): If a function that returns an unconstrained type is
18905 marked Inlined_Always and inlined, the call will be inlined and does
18906 not require the creation of a transient scope.
18907 (Check_Direct_Boolean_Op): Removed
18908 (Resolve_Comparison_Op): Remove call to above
18909 (Resolve_Equality_Op): Remove call to above
18910 (Resolve_Logical_Op): Inline above, since this is only call.
18911 (Valid_Conversion): Handle properly conversions between arrays of
18912 convertible anonymous access types.
18915 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
18916 the literal in an unchecked conversion, because GCC 4.x needs a static
18917 value for a string bound.
18919 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18920 Hristian Kirtchev <kirtchev@adacore.com>
18922 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
18923 components of the corresponding record, take into account component
18924 definitions that are access definitions.
18925 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
18926 procedure is not considered a dispatching call and will be expanded
18929 2006-02-13 Javier Miranda <miranda@adacore.com>
18931 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
18932 controlling argument of the dispatching call is an abstract interface
18933 class-wide type then we use it directly.
18934 Check No_Dispatching_Calls restriction.
18935 (Default_Prim_Op_Position): Remove the code that looks for the last
18936 entity in the list of aliased subprograms. This code was wrong in
18938 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
18939 when the source is compiled with the No_Dispatching_Calls restriction.
18940 (Init_Predefined_Interface_Primitives): No need to inherit primitives
18941 if we are compiling with restriction No_Dispatching_Calls.
18942 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
18943 subprograms if we are compiling under No_Dispatching_Calls restriction.
18944 (Make_DT): Generate a dispatch table with a single dummy entry if
18945 we are compiling with the No_Dispatching_Calls restriction. In
18946 addition, in this case we don't generate code that calls to the
18947 following run-time subprograms: Set_Type_Kind, Inherit_DT.
18948 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
18949 of this subprogram if compiling with the No_Dispatching_Calls
18951 (Expand_Type_Conversion): Instead of using the actual parameter,
18952 the argument passed as parameter to the conversion function was
18953 erroneously referenced by the expander.
18954 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
18955 Set_Predefined_Primitive_Op_Address and Set_Signature.
18956 (Expand_Dispatching_Call): Generate call to
18957 Get_Predefined_Prim_Op_Address for predefined primitives.
18958 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
18959 predefined primitives.
18960 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
18961 primitives we reserve one dummy entry to ensure that the tag does not
18962 point to some memory that is associated with some other object. In
18963 addition, remove all the old code that generated the assignments
18964 associated with the signature of the dispatch table and replace them
18965 by a call to the new subprogram Set_Signature.
18966 (Set_All_DT_Position): Change the algorithm because now we have a
18967 separate dispatch table associated with predefined primitive operations.
18968 (Expand_Interface_Conversion): In case of non-static offset_to_top
18969 add explicit dereference to get access to the object after the call
18970 to displace the pointer to the object.
18971 (Expand_Interface_Thunk): Modify the generation of the actual used
18972 in the calls to the run-time function Offset_To_Top to fulfil its
18974 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
18976 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18978 * exp_dist.adb (Copy_Specification): For access parameters, copy
18979 Null_Exclusion flag, which will have been set for stream subprograms
18982 2006-02-13 Pascal Obry <obry@adacore.com>
18984 * expect.c (__gnat_expect_portable_execvp): New implementation. The
18985 previous implementation was using the C runtime spawnve routine but
18986 the corresponding wait was using directly the Win32 API. This was
18987 causing some times a lock when waiting for an event using
18988 WaitForSingleObject in __gnat_waitpid. This new implementation uses
18989 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
18990 API fixes this problem.
18992 2006-02-13 Robert Dewar <dewar@adacore.com>
18994 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
18997 2006-02-13 Thomas Quinot <quinot@adacore.com>
18999 * exp_pakd.ads: Fix typos in comments.
19001 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
19002 array reference that is an explicit dereference, mark the converted
19003 (packed) array reference as analyzed to prevent a forthcoming
19004 reanalysis from resetting its type to the original (non-packed) array
19007 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19008 Javier Miranda <miranda@adacore.com>
19009 Eric Botcazou <ebotcazou@adacore.com>
19011 * exp_util.ads, exp_util.adb (Find_Prim_Op,
19012 Is_Predefined_Primitive_Operation): When
19013 searching for the predefined equality operator, verify that operands
19014 have the same type.
19015 (Is_Predefined_Dispatching_Operation): Remove the code that looks
19016 for the last entity in the list of aliased subprograms. This code
19017 was wrong in case of renamings.
19018 (Set_Renamed_Subprogram): New procedure
19019 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
19020 Exp_Type constant computed when entering this subprogram.
19021 (Known_Null): New function
19022 (OK_To_Do_Constant_Replacement): New function
19023 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
19024 (Side_Effect_Free): An attribute reference 'Input is not free of
19025 side effect, unlike other attributes that are functions. (from code
19027 (Remove_Side_Effects): Expressions that involve packed arrays or records
19028 are copied at the point of reference, and therefore must be marked as
19029 renamings of objects.
19030 (Is_Predefined_Dispatching_Operation): Return false if the operation is
19031 not a dispatching operation.
19034 (Remove_Side_Effects): Lift enclosing type conversion nodes for
19035 elementary types in all cases.
19037 2006-02-13 Javier Miranda <miranda@adacore.com>
19039 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
19040 task types when accessing to the corresponding record type.
19041 Remove '!' in warning message.
19043 2006-02-13 Olivier Hainque <hainque@adacore.com>
19045 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
19046 to avoid useless and space inefficient overalignments on targets where
19047 Max_Alignment is larger than 16.
19049 2006-02-13 Pascal Obry <obry@adacore.com>
19051 * g-catiio.adb (Sec_Number): New type used to compute the number of
19052 seconds since 1-1-1970.
19053 (Image) [Natural]: The parameter was an Integer, as we can't deal with
19054 negative numbers (years, months...) it is better to have a Natural here.
19056 (Image) [Number]: Change parameter from Long_Integer to Number.
19057 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
19058 overflow for dates past year 2038.
19060 2006-02-13 Matthew Heaney <heaney@adacore.com>
19062 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
19065 2006-02-13 Arnaud Charlet <charlet@adacore.com>
19067 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
19069 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
19070 finalization can occur normally.
19072 2006-02-13 Vincent Celier <celier@adacore.com>
19074 * gnatcmd.adb (Rules_Switches): New table
19075 (Add_To_Rules_Switches): New procedure
19076 (GNATCmd): For command CHECK, put all options following "-rules" in the
19077 Rules_Switches table. Append these -rules switches after the -cargs
19080 2006-02-13 Robert Dewar <dewar@adacore.com>
19082 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
19083 These two cases were generating incorrect output, and if this unit
19084 was built with checks on, generated a discriminant mismatch constraint
19087 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19088 Robert Dewar <dewar@adacore.com>
19090 * lib-xref.adb (Get_Type_Reference): For a private type whose full
19091 view is an array type, indicate the component type as well, for
19092 navigation purposes.
19093 (Generate_Reference): Don't consider array ref on LHS to be a case
19094 of violating pragma Unreferenced.
19095 Do not give Ada 2005 warning except on real reference.
19097 2006-02-13 Vincent Celier <celier@adacore.com>
19099 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
19100 main source, add switch -mdebug-main=_ada_ so that the executable can
19101 be debugged by the standard VMS debugger.
19102 (Gnatmake): Set No_Main_Subprogram to True when there is no main
19103 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
19104 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
19105 of the last source, as the binding and linking phases are never
19107 Set all executable obsolete when rebuilding a library.
19109 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
19112 2006-02-13 Javier Miranda <miranda@adacore.com>
19115 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
19116 code to improve the error message reported when the program has
19117 declarations of abstract interface types and it is not compiled with
19118 the -gnat05 switch.
19119 (P_Access_Definition): Reorganize the code to improve the error
19120 message reported when the new Ada 2005 syntax for anonymous
19121 access types is used and the program is not compiled with the
19124 2006-02-13 Robert Dewar <dewar@adacore.com>
19126 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,
19127 stylesw.ads, usage.adb, vms_data.ads: Implement -gnatyI switch
19130 2006-02-13 Javier Miranda <miranda@adacore.com>
19132 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser
19133 against source containing syntax errors.
19135 2006-02-13 Vincent Celier <celier@adacore.com>
19137 * prj.adb (Reset): Initialize the first element of table Namings with
19138 the standard naming data.
19140 2006-02-13 Vincent Celier <celier@adacore.com>
19142 * prj.ads (Error_Warning): New enumeration type
19144 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
19145 unknown, use the location of the project to report the error.
19146 (When_No_Sources): New global variable
19147 (Report_No_Ada_Sources): New procedure

19161 Prj.Nmsc.Check with parameter When_No_Sources.
19162 (Process): New parameter When_No_Sources. Call Check with parameter
19164 (Copy_Package_Declarations): New procedure to copy renamed parameters
19165 and setting the location of the declared attributes to the location

19174 When removing nodes (attributes Source_Dirs, Source_Files,
19175 Source_List_File and package Naming), save the comments and attach the
19176 saved comments to the newly created nodes.
19177 Do not add a with clause for the naming package if one already exists.

19186 aliased entities to look for the overriden abstract interface
19188 (Is_Interface_Subprogram): Complete documentation.
19189 (Check_Dispatching_Operation): Do not generate code to register the
19190 operation in the dispatch table if the source is compiled with
19191 restriction No_Dispatching_Calls.
19192 (Override_Dispatching_Operation): Check for illegal attempt to override
19193 No_Return procedure with procedure that is not No_Return
19194 (Check_Dispatching_Call): Suppress the check for an abstract operation
19195 when the original node of an actual is a tag-indeterminate attribute
19196 call, since the attribute, which must be 'Input, can never be abstract.
19197 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
19198 call to the Input attribute (even when rewritten).
19199 (Propagate_Tag): Augment comment to indicate the possibility of a call
19200 to an Input attribute.
19202 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
19203 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

19210 2006-02-13 Douglas Rupp <rupp@adacore.com>
19212 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
19214 2006-02-13 Javier Miranda <miranda@adacore.com>
19216 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
19217 handles default-initialized components to keep separate the management
19218 of this feature but also avoid the unrequired resolution and
19219 expansion of components that do not have partially initialized
19221 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
19222 (Check_Bounds): Likewise.
19223 (Check_Length): Likewise.
19225 2006-02-13 Javier Miranda <miranda@adacore.com>
19226 Ed Schonberg <schonberg@adacore.com>
19228 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
19229 abstract interface type call analyze_and_resolve to expand the type
19230 conversion into the corresponding displacement of the
19231 reference to the base of the object.
19232 (Eval_Attribute, case Width): For systems where IEEE extended precision
19233 is supported, the maximum exponent occupies 4 decimal digits.
19234 (Accessibility_Message): Add '\' in 2-line warning message.
19235 (Resolve_Attribute): Likewise.
19236 (case Attribute_Access): Significantly revise checks
19237 for illegal access-to-subprogram Access attributes to properly enforce
19238 the rules of 3.10.2(32/2).
19239 Diagnose use of current instance with an illegal attribute.
19241 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
19243 (Enclosing_Generic_Unit): New function to return a node's innermost
19244 enclosing generic declaration node.
19245 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
19246 (Type_Access_Level): The accessibility level of anonymous acccess types
19247 associated with discriminants is that of the current instance of the
19248 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
19249 (Compile_Time_Constraint_Error): Handle case of conditional expression.
19250 (Kill_Current_Values_For_Entity): New function
19251 (Enter_Name): Change formal type to Entity_Id
19253 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
19254 Ed Schonberg <schonberg@adacore.com>
19255 Gary Dismukes <dismukes@adacore.com>
19257 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
19258 Analyze_Compilation_Unit.
19259 Detect and warn on redundant with clauses detected in a package spec
19260 and/or body when -gnatwr is used.
19261 (Analyze_Context): Analyze config pragmas before other items
19262 (Install_Context_Items): Don't analyze config pragmas here
19263 (Install_Limited_Withed_Unit): Set limited entity of package in
19264 with_clause so that cross-reference information or warning messages on
19265 unused packages can be properly generated
19266 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
19267 has Error_Posted set. Prevent infinite loops in illegal programs.
19268 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
19269 to the point of the error test requiring the current unit to be private.
19270 This ensures that private with clauses are not exempted from the basic
19271 checking for being a descendant of the same library unit parent as a
19272 withed private descendant unit.
19273 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
19274 handle private with clauses properly, as well as to account for cases
19275 where the withed unit is a public descendant of a private ancestor
19276 (in which case the current unit must be a descendant of the private
19277 ancestor's parent). The spec comments were updated accordingly. Also,
19278 the old error message in this subprogram was replaced with error
19279 messages that mirror the errors tested and reported by
19280 Check_Private_Child_Unit.
19281 Parameter and variable names improved for readability.
19282 (Install_Limited_Context_Clauses): Remove test for a withed unit being
19283 private as the precondition for calling
19284 Check_Private_Limited_Withed_Unit since that subprogram has been
19285 revised to test public units as well as private units.

19289 Ed Schonberg <schonberg@adacore.com>
19290 Javier Miranda <miranda@adacore.com>
19292 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
19293 that Scope_Stack.First = 1.
19294 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19295 were not always properly handled previously.
19296 (Formal_Entity): Complete rewrite, to handle properly some complex case
19297 with multiple levels of parametrization by formal packages.
19298 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
19299 to the corresponding derived type declaration for proper semantics.
19301 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
19302 (Check_Component): Enforce restriction on components of
19303 unchecked_unions: a component in a variant cannot contain tasks or
19305 (Unchecked_Union): Allow nested variants and multiple discriminants, to
19307 Add pragma Ada_2005 (synonym for Ada_05)
19308 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19309 were not always properly handled previously.
19310 Document that pragma Propagate_Exceptions has no effect
19311 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
19312 (Set_Convention_From_Pragma): Check that if a convention is
19313 specified for a dispatching operation, then it must be
19314 consistent with the existing convention for the operation.
19315 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
19316 longer required to specify an vtable-ptr component in the record. For
19317 compatibility reasons we leave the support for the previous definition.
19318 (Analyze_Pragma, case No_Return): Allow multiple arguments
19320 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
19321 non-overrideen inherited operation with a controlling result as
19322 illegal only its implicit declaration comes from the derived type
19323 declaration of its result's type.
19324 (Check_Possible_Deferred_Completion): Relocate the object definition
19325 node of the subtype indication of a deferred constant completion rather
19326 than directly analyzing it. The analysis of the generated subtype will
19327 correctly decorate the GNAT tree.
19328 (Record_Type_Declaration): Check whether this is a declaration for a
19329 limited derived record before analyzing components.
19330 (Analyze_Component_Declaration): Diagnose record types not explicitly
19331 declared limited when a component has a limited type.
19332 (Build_Derived_Record_Type): Code reorganization to check if some of
19333 the inherited subprograms of a tagged type cover interface primitives.
19334 This check was missing in case of a full-type associated with a private
19336 (Constant_Redeclaration): Check that the subtypes of the partial and the
19337 full view of a constrained deferred constant statically match.
19338 (Mentions_T): A reference to the current type in an anonymous access
19339 component declaration must be an entity name.
19340 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
19341 class_wide type to refer to full type, not to the incomplete one.
19342 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
19343 available. Required to give support to the certified run-time.
19344 (Analyze_Component_Declaration): In case of anonymous access components
19345 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
19346 (Process_Discriminants): For an access discriminant, use the
19347 discriminant specification as the associated_node_for_itype, to
19348 simplify accessibility checks.
19350 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19351 Javier Miranda <miranda@adacore.com>
19353 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
19354 abstract interpretations on an operator, remove interpretations that
19355 yield Address or a type derived from it, if one of the operands is an
19357 (Try_Object_Operation.Try_Primitive_Operation,
19358 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
19359 location when creating the new reference to a primitive or class-wide
19360 operation as a part of rewriting a subprogram call.
19361 (Try_Primitive_Operations): If context requires a function, collect all
19362 interpretations after the first match, because there may be primitive
19363 operations of the same type with the same profile and different return
19364 types. From code reading.
19365 (Try_Primitive_Operation): Use the node kind to choose the proper
19366 operation when a function and a procedure have the same parameter
19368 (Complete_Object_Operation): If formal is an access parameter and prefix
19369 is an object, rewrite as an Access reference, to match signature of
19370 primitive operation.
19371 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
19372 by an expanded name with prefix Standard, when the operands are of an
19373 anonymous access type.
19374 (Remove_Abstract_Operations): If the operation is abstract because it is
19375 inherited by a user-defined type derived from Address, remove it as
19376 well from the set of candidate interpretations of an overloaded node.
19377 (Analyze_Membership_Op): Membership test not applicable to cpp-class
19380 2006-02-13 Bob Duff <duff@adacore.com>
19382 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
19383 redundant use clauses.
19384 In particular, if the scope of two use clauses overlaps, but one is not
19385 entirely included in the other, we should not warn. This can happen
19386 with nested packages.
19387 (Analyze_Subprogram_Renaming): Protect the compiler against previously
19388 reported errors. The bug was reported when the compiler was built
19389 with assertions enabled.
19390 (Find_Type): If the node is a 'Class reference and the prefix is a
19391 synchronized type without a corresponding record, return the type
19394 2006-02-13 Javier Miranda <miranda@adacore.com>
19396 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
19397 if this is the full-declaration associated with a private declaration
19398 that implement interfaces, then the private type declaration must be
19400 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
19401 as aliased. The use of the 'access attribute is not available for such
19402 object (for this purpose the object should be explicitly marked as
19403 aliased, but being an anonymous type this is not possible).
19405 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19406 Robert Dewar <dewar@adacore.com>
19408 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
19409 compilation unit is an elaboration scope.
19410 (Add_Task_Proc): Add '\' in 2-line warning message.
19411 (Activate_All_Desirable): Deal with case of unit with'ed by parent
19413 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19414 Javier Miranda <miranda@adacore.com>
19416 * sem_type.adb (Write_Overloads): Improve display of candidate
19418 (Add_One_Interp): Do not add to the list of interpretations aliased
19419 entities corresponding with an abstract interface type that is an
19420 immediate ancestor of a tagged type; otherwise we have a dummy
19421 conflict between this entity and the aliased entity.
19422 (Disambiguate): The predefined equality on universal_access is not
19423 usable if there is a user-defined equality with the proper signature,
19424 declared in the same declarative part as the designated type.
19425 (Find_Unique_Type): The universal_access equality operator defined under
19426 AI-230 does not cover pool specific access types.
19427 (Covers): If one of the types is a generic actual subtype, check whether
19428 it matches the partial view of the other type.
19430 2006-02-13 Thomas Quinot <quinot@adacore.com>
19432 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
19433 line. This is necessary to allow In_Extended_Main_Unit to provide
19434 correct results for itypes while writing out expanded source.
19435 (Close_File): No need to update the source_index_table here since it's
19436 now done for each line.
19438 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19439 Robert Dewar <dewar@adacore.com>
19441 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
19442 preserve the source unit where the itype is declared, and prevent a
19444 (Note_Implicit_Run_Time_Call): New procedure
19445 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
19448 * sprint.ads: Document use of $ for implicit run time routine call
19450 2006-02-13 Quentin Ochem <ochem@adacore.com>
19452 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
19455 2006-02-13 Bob Duff <duff@adacore.com>
19457 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
19458 Scan_Unsigned, so we do not scan leading blanks and sign twice.
19459 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19460 raise Constraint_Error.
19462 * s-vallli.adb (Scan_Long_Long_Integer): Call
19463 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
19464 do not scan leading blanks and sign twice.
19465 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19466 raise Constraint_Error.
19468 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
19469 Scan_Long_Long_Unsigned): Split out most of the processing from
19470 Scan_Long_Long_Unsigned out into
19471 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
19472 This prevents scanning leading blanks and sign twice.
19473 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
19476 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
19477 out most of the processing from Scan_Unsigned out into
19478 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
19479 This prevents scanning leading blanks and sign twice.
19481 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
19482 use with Modular'Value attribute.
19483 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

19681 * a-taster.ads, a-taster.adb: New files.
19683 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
19684 link to the version that does nothing. This way the task termination
19685 routine is not executed twice for the environment task when finishing
19686 because of an unhandled exception.
19688 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
19689 handler because of an unhandled exception.
19691 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

19697 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
19698 non-tasking version of the soft link for task termination. We do
19699 nothing since if we are using the non-tasking version it
19700 means that the task termination functionality is not used.
19701 (Null_Finalize_Global_List): Add this null version for the procedure
19702 in charge of finalizing the global list for controlled objects.
19703 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
19704 instead for handling run-time termination in a more flexible way.
19705 (Adafinal_NT): This new procedure will take care of finalizing the
19706 global list for controlled objects if needed, but no tasking
19709 * s-tarest.adb (Task_Lock): Do not try to lock again the
19710 Global_Task_Lock if we already own it. Otherwise, we get blocked in
19711 some run-time operations.
19712 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
19713 until all nested locks have been released.
19714 (Task_Wrapper): Call the fall-back task termination handler. It
19715 applies to all tasks but the environment task.
19716 (Finalize_Global_Tasks): Add the call for the task termination
19717 procedure for the environment task.
19718 (Task_Wrapper): suppress warnings around declaration of
19719 Secondary_Stack_Address.
19721 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
19722 moved to the Common_ATCB record.
19723 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
19724 Common_ATCB record.
19725 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
19726 Common_ATCB record.
19728 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
19729 Fall_Back_Handler, and Specific_Handler.
19731 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
19732 defined in Ada.Task_Termination, to avoid circular dependencies.
19733 (Termination_Handler): Redefine this type here, alredy defined in
19734 Ada.Task_Termination, for avoiding circular dependencies.
19735 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
19736 for storing task termination handlers. In addition,
19737 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
19738 Common_ATCB because it is used by both the regular and the restricted
19740 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
19741 Common_ATCB because it is used by both the regular and the restricted
19743 (Common_ATCB): Added a dynamic task analyzer field.
19745 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
19746 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

19748 tasks but the environment task.
19749 (Finalize_Global_Tasks): Call the task termination procedure for the
19750 environment task. The call to Finalize_Global_List is now performed
19751 using the soft links mechanism.
19752 (Task_Wrapper): added dynamic stack analysis.
19754 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
19755 potentially blocking operations has been moved from
19756 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
19757 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
19758 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
19759 this run-time check.
19761 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
19762 of task termination procedure.
19763 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

19805 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
19806 to the specification because the frontend generates code that uses this
19808 (Set_Interface_Table): Add missing assertion.
19809 Update documentation describing the run-time structure.
19810 (Displace): New subprogram that displaces the pointer to the object
19811 to reference one of its secondary dispatch tables.
19812 (IW_Membership): Modified to use the new table of interfaces.
19813 (Inherit_TSD): Modified to use the new table of interfaces.
19814 (Register_Interface_Tag): Use the additional formal to fill the
19815 contents of the new table of interfaces.
19816 (Set_Interface_Table): New subprogram that stores in the TSD the
19817 pointer to the table of interfaces.

19831 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
19832 in all the calls to Expand_Interface_Thunk. Instead of referencing the
19833 record component containing the tag of the secondary dispatch table we
19834 have to use the Offset_To_Top run-time function to get this information;
19835 otherwise if the pointer to the base of the object has been displace
19836 we get a wrong value if we use the 'position attribute.
19838 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
19839 all the calls to Expand_Interface_Thunk.
19840 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
19841 interfaces; hence the call to Set_Interface_Table was clearly wrong.

19843 ensure that the interfaces implemented by the ancestors are placed
19844 at the header of the generated list.
19845 (Expand_Interface_Conversion): Handle the case in which the displacement
19846 associated with the interface conversion is not statically known. In
19847 this case we generate a call to the new run-time subprogram Displace.

19849 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
19850 Get_Tagged_Kind and Set_Tagged_Kind.
19851 (Tagged_Kind): New function that determines the tagged kind of a type
19852 with respect to limitedness and concurrency and returns a reference to

19858 secondary dispatch table respectively of a tagged type.
19860 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

19874 RE_TK_Tagged, RE_TK_Task.
19876 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
19877 Init_Secondary_Tags_Internal to allow its use with interface types and
19878 also to generate the code for the new additional actual required
19879 by Set_Offset_To_Top.
19880 (Build_Init_Statements): In case of components associated with abstract
19881 interface types there is no need to generate a call to its IP.
19882 (Freeze_Record_Type): Generate Select Specific Data tables only for
19884 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
19885 the bodies and specifications of the predefined primitive operations

19891 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
19892 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
19893 properly protected objects and attach handler in the case of the
19894 restricted profile.
19895 Move embeded package Select_Expansion_Utilities into a separate external
19897 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
19898 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
19899 (Build_K, Build_S_Assignment): New subprograms, part of the select
19900 expansion utilities.

19905 2005-12-09 Olivier Hainque <hainque@adacore.com>
19907 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
19908 pointer initialization values. Make a SAVE_EXPR instead. Add comments
19909 about the use and expansion of SAVE_EXPRs in the various possible
19910 renaming handling cases.
19911 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
19912 abusing DECL_FCONTEXT.

20082 are implemented by the ancestors.
20083 (Derived_Type_Declaration): If the parent of the full-view is an
20084 interface perform a transformation of the tree to ensure that it has
20085 the same parent than the partial-view. This simplifies the job of the
20086 expander in order to generate the correct object layout, and it is
20087 needed because the list of interfaces of the full-view can be given in
20089 (Process_Full_View): The parent of the full-view does not need to be
20090 a descendant of the parent of the partial view if both parents are
20092 (Analyze_Private_Extension_Declaration): If declaration has an explicit
20093 "limited" the parent must be a limited type.
20094 (Build_Derived_Record_Type): A derived type that is explicitly limited
20095 must have limited ancestor and progenitors.
20096 (Build_Derived_Type): Ditto.

20459 actual constrained subtype.

20614 to get advantage of the new maybe_stabilize_reference interface, to
20615 ensure that what we reference is indeed stabilized instead of relying
20616 on assumptions on what the stabilizer does.
20617 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
20618 type imported through a limited_with clause, use its non-limited view.
20619 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
20621 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
20622 of #if sections + explicit comparisons of convention identifiers.
20623 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
20624 before early-returning for certain types when code generation is
20626 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
20627 nullification of gnu_expr we do for objects with address clause and
20628 that we are not defining.
20629 (elaborate_expression_1): Do not create constants when creating
20630 variables needed by the debug info: the dwarf2 writer considers that
20631 CONST_DECLs is used only to represent enumeration constants, and emits
20633 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
20634 object with an address clause into an indirect reference, drop the
20635 initializing expression.
20637 (STACK_CHECK_BUILTIN): Delete.
20638 (STACK_CHECK_PROBE_INTERVAL): Likewise.

20645 related): For a prefix that is a dereference of a fat or thin pointer,
20646 if there is an actual subtype provided by the front-end, use that
20647 subtype to build an actual type with bounds template.
20648 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
20649 is provided by the front-end, use that subtype to compute the size of
20650 the deallocated object.
20651 (gnat_to_gnu): When adding a statement into an elaboration procedure,
20652 check for a potential violation of a No_Elaboration_Code restriction.
20653 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
20654 with extra arguments to control whether to recurse through non-values
20655 and to let the caller know if the stabilization has succeeded.

20657 maybe_stabilize, for common uses without restriction on lvalues and
20658 without need to check for the success indication.
20659 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
20660 pass false instead of 0 as the FORCE argument which is a bool.
20661 (Identifier_to_gnu): Remove checks ensuring that an renamed object
20662 attached to a renaming pointer has been properly stabilized, as no such
20663 object is attached otherwise.
20664 (call_to_gnu): Invoke create_var_decl to create the temporary when the
20665 function uses the "target pointer" return mechanism.
20666 Reinstate conversion of the actual to the type of the formal
20667 parameter before any other specific treatment based on the passing
20668 mechanism. This turns out to be necessary in order for PLACEHOLDER
20669 substitution to work properly when the latter type is unconstrained.
20671 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
20673 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
20674 with extra arguments to control whether to recurse through non-values
20675 and to let the caller know if the stabilization has succeeded.
20677 * utils2.c (gnat_build_constructor): Only sort the fields for possible
20678 static output of record constructor if all the components are constant.
20679 (gnat_build_constructor): For a record type, sort the list of field
20680 initializers in increasing bit position order.
20681 Factor common code to build a storage type for an unconstrained object
20682 from a fat or thin pointer type and a constrained object type.
20683 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
20684 types variants, and process special cases of VIEW_CONVERT expressions
20685 as their NOP_EXPR counterpart to ensure we get to the
20686 CORRESPONDING_VARs associated with CONST_DECls.
20687 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
20688 on the right-hand side.
20690 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
20692 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
20693 are converting back to its original type.
20694 (convert) <JM input>: Fallthrough regular conversion code instead of
20695 extracting the object if converting to a type variant.
20696 (create_var_decl): When a variable has an initializer requiring code
20697 generation and we are at the top level, check for a potential violation
20698 of a No_Elaboration_Code restriction.
20699 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
20700 SIZE and SIZE_UNIT which we need for later back-annotations.
20701 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
20702 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
20703 is an unchecked union.
20704 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
20705 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
20706 main variant, just replace the VIEW_CONVERT_EXPR.

20842 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
20843 for task component, in the case of a limited aggregate. The enclosed

20883 access to unconstrained packed array type, annotate the dereference
20884 with an actual subtype so GIGI can make a correct size computation.
20885 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
20886 'Unrestricted_Access, if the designated type is an interface we
20887 add a type conversion to force the displacement of the pointer
20888 to the secondary dispatch table.
20889 Use Universal_Real instead of Long_Long_Float when we need a high
20890 precision float type for the generated code (prevents gratuitous
20891 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
20892 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
20893 'Terminated for task interface class-wide objects. Generate a call to
20894 the predefined dispatching routine used to retrieve the _task_id from
20895 a task corresponding record.

20924 the return value into its actual subtype in order to help the backend
20925 to return the actual size instead of the maximum. This is another

20953 2005-11-14 Robert Dewar <dewar@adacore.com>
20955 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

20957 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
20960 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

20975 attribute of the N_Free_Statement.
20976 Generate itype for classwide designated object in both cases of
20977 user-specified storage pool: specific and class-wide, not only in the
20979 Raise CE when trying to set a not null access type object to null.

21256 In addition some minor reorganization of the code has been done to
21257 leave it more clear.
21258 (Analyze_Type_Declaration): If type has previous incomplete tagged
21259 partial view, inherit properly its primitive operations.

21315 whose default is abstract because the object type itself is abstract.
21316 (Find_Type): If the type is incomplete and appears as the prefix of a
21317 'Class reference, it is tagged, and its list of primitive operations
21318 must be initialized properly.
21319 (Chain_Use_Clauses): When chaining the use clauses that appear in the
21320 private declaration of a parent unit, prior to compiling the private
21321 part of a child unit, find on the scope stack the proper parent entity
21322 on which to link the use clause.

21346 remove address operations.
21347 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
21348 statement to inhibit warning.
21349 (Resolve_Unary_Op): Do not produce a warning when
21350 processing an expression of the form -(A mod B)
21351 Use Universal_Real instead of Long_Long_Float when we need a high

21354 (Resolve_Concatenation_Arg): Improve error message when argument is an
21355 ambiguous call to a function that returns an array.
21356 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

22296 2005-09-01 Robert Dewar <dewar@adacore.com>
22298 * checks.adb (Check_Needed): New procedure, deals with removing checks
22299 based on analysis of short-circuited forms. Also generates warnings for
22300 improper use of non-short-circuited forms.
22303 2005-09-01 Robert Dewar <dewar@adacore.com>
22305 * a-ztexio.adb, a-textio.adb, a-witeio.adb: Replace bad range checks
22308 2005-09-01 Robert Dewar <dewar@adacore.com>

22316 (Error_Msg_Warn): New variable for < insertion char.
22317 * prj-nmsc.adb: Implement new errout insertion char < (conditional
22319 (Check_For_Source): Change value of Source_Id only after the current
22320 source has been dealt with.
22322 2005-09-01 Robert Dewar <dewar@adacore.com>
22323 Doug Rupp <rupp@adacore.com>
22325 * exp_attr.adb: Handle vax fpt for 'Valid attribute

22331 Hristian Kirtchev <kirtchev@adacore.com>
22332 Javier Miranda <miranda@adacore.com>
22334 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
22335 from object notation, the original node is unanalyzed and carries no
22336 semantic information, so that accessiblity checks must be performed on
22337 the type of the actual itself.
22338 (Expand_N_Subprogram_Declaration): Change last actual parameter for
22339 compatibility with Build_Protected_Sub_Specification.
22340 (Check_Overriding_Inherited_Interfaces): Add suport to handle
22341 overloaded primitives.
22342 (Register_Interface_DT_Entry): Use the new name of the formal
22343 the the calls to Expand_Interface_Thunk
22345 * exp_dbug.ads: Augment comments on encoding of protected types to
22346 include the generation of dispatching subprograms when the type
22347 implements at least one interface.
22349 * lib.ads: Extend information in Load_Stack to include whether a given
22350 load comes from a Limited_With_Clause.
22352 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
22353 whether a potential circularity is harmless, because it includes units
22354 loaded through a limited_with clause. Extends previous treatment which
22355 did not handle properly arbitrary combinations of limited and
22356 non-limited clauses.
22358 2005-09-01 Nicolas Setton <setton@adacore.com>
22360 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
22361 to be encoded as typ___XBLU_lowerbound__upperbound instead of
22362 typ___XB_lowerbound__upperbound.
22364 2005-09-01 Thomas Quinot <quinot@adacore.com>
22366 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
22367 dummy access formal for RACW/RAS TypeCode TSS.
22368 (Build_TypeCode_Call): Do not generate dummy null access actual for
22369 calls to the TypeCode TSS.
22371 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22373 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
22374 fully qualified name, to distinguish instances with the same local name.
22376 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
22379 2005-09-01 Robert Dewar <dewar@adacore.com>

22384 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
22386 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
22387 (Free): New deallocation procedure for filter elements
22388 (Close): Deallocate any existing filter for the concerned connection
22390 2005-09-01 Laurent Pautet <pautet@adacore.com>
22392 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
22393 position set is provided, we compute one in order to reduce the maximum
22394 length of the keys. This computation first selects a character
22395 position between 1 and the minimum length of the keys in order to
22396 avoid reducing one of the keys to an empty string.
22397 (Initialize, Compute): When the ratio V to K is too low, the algorithm
22398 does not converge. The initialization procedure now comes with a
22399 maximum number of iterations such that when exceeded, an exception is
22400 raised in Compute. The user can initialize this ratio to another value
22402 Reformating and updated headers.
22404 2005-09-01 Javier Miranda <miranda@adacore.com>
22406 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
22407 that given an entity T creates and returns an Itype that duplicates the
22408 contents of T. The returned Itype has the null-exclusion
22409 attribute set to True, and its Etype attribute references T
22410 to keep the association between the two entities.
22411 Update copyright notice
22413 * sem_aggr.adb (Check_Can_Never_Be_Null,
22414 Aggregate_Constraint_Checks, Resolve_Aggregate,
22415 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
22417 * sem_ch5.adb (Analyze_Assignment): Code cleanup.
22419 2005-09-01 Gary Dismukes <dismukes@adacore.com>
22420 Robert Dewar <dewar@adacore.com>
22421 Hristian Kirtchev <kirtchev@adacore.com>
22423 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
22426 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
22428 Call Set_Result_Definition instead of Set_Subtype_Mark.
22429 (P_Subprogram_Specification): Add parsing of anonymous access result
22430 plus null exclusions. Call Set_Result_Definition instead of
22433 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
22434 (P_Access_Type_Definition): Add parsing for an anonymous access result
22435 subtype, plus parsing for null exclusions. Call Set_Result_Definition
22436 instead of Set_Subtype_Mark.
22438 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
22439 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
22440 (Result_Definition): New function for N_Function_Specifications.
22441 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
22442 N_Function_Specification.
22443 (Set_Null_Exclusion_Present): Allow this flag for
22444 N_Function_Specification.
22445 (Set_Result_Definition): New procedure for N_Function_Specifications.
22446 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
22447 and N_Function_Specification.
22449 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
22450 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
22451 Add support for LIMITED NEW for Ada 2005 AI-419
22452 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
22453 syntax for anonymous access results.
22454 Replace Subtype_Mark field by Result_Definition in
22455 N_Function_Specification and N_Access_Definition specs.
22456 Add Null_Exclusion_Present to spec of N_Function_Specification.
22457 (Result_Definition): New function for N_Function_Specification and
22458 N_Access_Function_Definition.
22459 (Set_Result_Definition): New procedure for N_Function_Specification and
22460 N_Access_Function_Definition.
22462 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
22463 Result_Definition for cases of N_Access_Function_Definition and
22464 N_Function_Specification.
22465 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
22467 2005-09-01 Vincent Celier <celier@adacore.com>
22469 * lib-writ.adb: Update Copyright notice
22470 (Write_With_Lines): On platforms where file names are case-insensitive,
22471 record the file names in lower case.
22472 (Write_ALI): For D lines, on platforms where file names are
22473 case-insensitive, record the file names in lower case.
22475 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22476 Emmanuel Briot <briot@adacore.com>
22478 * lib-xref.adb (Output_Overridden_Op): Display information on
22479 overridden operation.
22481 * lib-xref.ads: Add documentation on overridden operations.
22483 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
22486 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
22487 overriding entity information.
22489 2005-09-01 Vincent Celier <celier@adacore.com>
22491 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
22492 including those that are inherited.
22494 2005-09-01 Robert Dewar <dewar@adacore.com>
22496 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
22498 * par-prag.adb: Implement new pragma Debug_Policy
22500 * sem_prag.adb Implement new pragma Debug_Policy
22501 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
22502 Component_Size attribute specification. Give warning for ignored pragma
22505 * snames.h, snames.ads, snames.adb: Introduce entries in
22506 Preset_Names for Name_Disp_Asynchronous_Select,
22507 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
22508 Name_Disp_Timed_Select.
22509 New pragma Debug_Policy
22511 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
22513 Switch -gnata also sets Debug_Pragmas_Enabled
22515 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
22516 handle an explicit -gnata when compiling predefined files.
22518 2005-09-01 Vincent Celier <celier@adacore.com>
22520 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
22521 directories of projects that have no Ada sources.
22523 2005-09-01 Robert Dewar <dewar@adacore.com>
22525 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
22526 (makes a difference for wide characters)
22528 * widechar.adb, widechar.ads:
22529 Add Wide_Char_Byte_Count feature to count chars vs bytes
22531 2005-09-01 Thomas Quinot <quinot@adacore.com>
22532 Ed Schonberg <schonberg@adacore.com>
22533 Robert Dewar <dewar@adacore.com>
22535 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
22536 'Address attribute reference with an overloaded prefix, use the
22537 location of the prefix (not the location of the attribute reference) as
22538 the error location.
22539 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
22540 a function renaming thereof, is a valid prefix for 'Size (where it is
22541 intepreted as a function call).
22542 (Statically_Denotes_Entity): New predicate to determine whether the
22543 prefix of an array attribute can be considered static.
22546 (Eval_Attr): Fix failure to evaluate Component_Size for
22547 unconstrained arrays (resulted in wrong value in packed case, since
22548 back end cannot handle this case)
22550 2005-09-01 Robert Dewar <dewar@adacore.com>
22552 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
22553 error msgs for most common cases.
22554 Use new errout insertion char < (conditional warning)
22556 2005-09-01 Javier Miranda <miranda@adacore.com>
22557 Ed Schonberg <schonberg@adacore.com>
22559 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
22560 become local to the whole package.
22561 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
22562 the package was already analyzed the new algorithm "replaces" the
22563 real entities by the shadow ones. This is required to ensure that
22564 the order of these entities in the homonym chains does not change;
22565 otherwise we can have undefined references at linking time because
22566 in case of conflicts the external name of the entities will have
22567 a suffix that depends on the order of the entities in the chain.
22568 (Remove_Limited_With_Clause): Complementary code that completes the
22569 new algorithm and replaces the shadow entities by the real ones.
22570 (Install_Limited_Withed_Unit): When unchaining entities before the
22571 installation of the shadow entities, only regular entities of the
22572 public part must be taken into account. This is required to
22573 keep this routine in synch with the work done by Remove_Limited_
22575 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
22576 even if unit is analyzed, because the analysis of the unit is
22577 idempotent in any case, and the limited view of the unit may have to
22578 be installed for proper visibility.
22579 (Expand_Limited_With_Clause): Even if the unit in the implicit
22580 with_clause has been analyzed already, a limited view of the package
22581 must be built for the current context, if it does not exist yet.
22583 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22584 Javier Miranda <miranda@adacore.com>
22585 Gary Dismukes <dismukes@adacore.com>
22587 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
22588 defining entity for the instance body, make a new defining identifier
22589 rather than copying the entity of the spec, to prevent accidental
22590 sharing of the entity list.
22591 (Check_Private_View): When exchanging views of private types, build the
22592 list of exchanged views as a stack, to ensure that on exit the exchanges
22593 are undone in the proper order.
22594 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
22595 Restore the compilation environment in case of instantiation_error.
22596 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
22597 for an anonymous access result.
22598 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
22599 (Formal_Entity): Handle properly the case of a formal package that
22600 denotes a generic package renaming.
22602 2005-09-01 Thomas Quinot <quinot@adacore.com>
22604 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
22605 clause if the array aggregate is surrounded by parentheses.
22607 2005-09-01 Cyrille Comar <comar@adacore.com>
22608 Gary Dismukes <dismukes@adacore.com>
22609 Ed Schonberg <schonberg@adacore.com>
22610 Javier Miranda <miranda@adacore.com>
22612 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
22614 to check if a type is Constrained in cases related to code generation
22615 (rather than semantic checking) since otherwise we do not generate
22616 similar code for mutable private types depending if their
22617 discriminants are visible or not.
22618 (Check_Abstract_Overriding): Do not complain about failure to override
22619 the primitive operations used in dispatching selects since they will
22620 always be overriden at the freeze point of the type.
22621 (Access_Definition): Separate out handling for resetting the scope
22622 of an anonymous access function result type. Retrieve the scope
22623 of the associated function rather than using Current_Scope, which
22624 does not have a consistent value (depends on whether we're in the
22625 middle of analyzing formal parameters). Add ??? comment about
22626 finding a cleaner way to handle the special cases of scope setting.
22627 (Process_Incomplete_Dependents): A protected operation is never a
22628 dispatching operation (only its wrapper may be).
22629 (Build_Derived_Record_Type): In case of tagged private types that
22630 implement interfaces add derivation of predefined primitive
22632 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
22633 by two parameters that are used in case of derivation from abstract
22634 interface types: No_Predefined_Prims is used to avoid the derivation
22635 of predefined primitives from the interface, and Predefined
22636 Prims_Only is used to complete the derivation predefined primitives
22637 in case of private tagged types implementing interfaces.
22638 Fix typo in comments
22639 (Find_Interface_In_Descendant): Protect the frontend against
22640 wrong code with large circularity chains.
22641 (Is_Private_Overriding): Add support for entities overriding interface
22642 subprograms. The test failed because Entities associated with overriden
22643 interface subprograms are always marked as hidden (and used to build
22644 the secondary dispatch table); in this case the overriden entity is
22645 available through the field abstract_interface_alias (cf. override_
22646 dispatching_operation)
22647 (Access_Definition): Set the scope of the type to Current_Scope for the
22648 case of a function with an anonymous access result type.
22649 (Access_Subprogram_Declaration): Handle creation of the type entity for
22650 an access-to-function type with an anonymous access result.
22651 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
22652 in handling for N_Access_Function_Definition.
22653 (Analyze_Subtype_Declaration): Modify the text of error message.
22654 (Derived_Type_Declaration): Modify the text of error message.
22655 (Process_Subtype): Modify the text of error message plus cleanup
22656 of one redundant error message.
22657 (Analyze_Component_Declaration): Code cleanup.
22658 (Analyze_Object_Declaration): Code cleanup.
22659 (Analyze_Subtype_Declaration): Propagate the null-exclusion
22660 attribute in case of access types. Code cleanup.
22661 (Array_Type_Declaration): Code cleanup.
22662 (Process_Discriminants): Create the new null-excluding itype
22663 if required. Code cleanup.
22664 (Process_Subtype): Create the new null-excluding itype if
22665 required. Code cleanup.
22666 (Build_Derived_Record_Type): Code cleanup to avoid calling
22667 twice the subprogram derive_subprograms in case of private
22668 types that implement interfaces. In this particular case the
22669 subprogram Complete_Subprograms_Derivation already does the
22670 job associated with the second call.
22672 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
22673 conversion to the full view when generating an operation for a
22674 discriminant whose type may currently be private.
22676 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22677 Javier Miranda <miranda@adacore.com>
22679 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
22680 V (Obj.F), the rewriting does not involve the indexed component, but
22681 only the selected component itself.
22682 Do not apply the transformation if the analyzed node is an actual of a
22683 call to another subprogram.
22684 (Complete_Object_Operation): Retain the entity of the
22685 dispatching operation in the selector of the rewritten node. The
22686 entity will be used in the expansion of dispatching selects.
22687 (Analyze_One_Call): Improve location of the error message associated
22689 (Analyze_Selected_Component): No need to resolve prefix when it is a
22690 function call, resolution is done when parent node is resolved, as
22692 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
22693 when attempting to resolve a call transformed from its object notation.
22694 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
22695 of the argument list for each interpretation of the operation.
22696 (Try_Object_Operation): The designated type of an access parameter may
22697 be an incomplete type obtained through a limited_with clause, in which
22698 case the primitive operations of the type are retrieved from its full
22700 (Analyze_Call): If this is an indirect call, and the return type of the
22701 access_to_subprogram is incomplete, use its full view if available.
22703 2005-09-01 Javier Miranda <miranda@adacore.com>
22704 Gary Dismukes <dismukes@adacore.com>
22706 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
22707 access types the null-exclusion and access-to-constant attributes must
22709 (Analyze_Return_Statement): When the result type is an anonymous access
22710 type, apply a conversion of the return expression to the access type
22711 to ensure that appropriate accessibility checks are performed.
22712 (Analyze_Return_Type): For the case of an anonymous access result type,
22713 generate the Itype and set Is_Local_Anonymous_Access on the type.
22714 Add ??? placeholder for check to disallow returning a limited object
22715 in Ada 2005 unless it's an aggregate or a result of a function call.
22716 Change calls from Subtype_Mark to Result_Definition.
22717 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
22718 Result_Definition in call to Make_Function_Specification.
22719 (Build_Body_To_Inline): Change Set_Subtype_Mark to
22720 Set_Result_Definition.
22721 (Make_Inequality_Operator): Change formal Subtype_Mark to
22722 Result_Definition in call to Make_Function_Specification.
22723 (Process_Formals): Create the new null-excluding itype if required.
22724 (New_Overloaded_Entity): For an entity overriding an interface primitive
22725 check if the entity also covers other abstract subprograms in the same
22726 scope. This is required to handle the general case, that is, overriding
22727 other interface primitives and overriding abstract subprograms inherited
22728 from some abstract ancestor type.
22729 (New_Overloaded_Entity): For an overriding entity that comes from
22730 source, note the operation that it overrides.
22731 (Check_Conformance, Type_Conformant): Addition of one new formal
22732 to skip controlling formals in the analysis. This is used to
22733 handle overloading of abstract interfaces.
22734 (Base_Types_Match): Add missing case for types imported from
22735 limited-with clauses
22736 (New_Overloaded_Entity): Add barrier to protect the use of
22737 the "alias" attribute.
22739 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22741 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
22742 verify that the procedure and the entry are mode conformant.
22743 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
22744 as a different operator, which is often a cut-and-paste error.
22746 2005-09-01 Javier Miranda <miranda@adacore.com>
22747 Ed Schonberg <schonberg@adacore.com>
22749 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
22750 used in controlling parameters exclude null because it is necessary to
22751 read the tag to dispatch, and null has no tag.
22752 (Override_Dispatching_Operation): If the previous operation is inherited
22753 from an interface, it becomes hidden and does not participate in later
22756 2005-09-01 Javier Miranda <miranda@adacore.com>
22757 Ed Schonberg <schonberg@adacore.com>
22758 Gary Dismukes <dismukes@adacore.com>
22760 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
22761 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
22762 the expander will generate the corresponding run-time check to evaluate
22764 (Resolve_Call): Check for legal type of procedure name or prefix that
22765 appears as a trigger in a triggering alternative.
22766 (Valid_Conversion): If expression is ambiguous and the context involves
22767 an extension of System, remove System.Address interpretations.
22768 (Resolve_Qualified_Expression): Reject the case of a specific-type
22769 qualification applied to a class-wide argument. Enhance comment
22770 to explain checking of Original_Node.
22771 (Resolve_Type_Conversion): The location of the error message was not
22772 general enough to handle the general case and hence it has been removed.
22773 In addition, this patch improves the text of the message.
22774 (Resolve_Type_Conversion): Add missing support for access to interface
22776 (Resolve_Type_Conversion): If the target is a class-wide interface type,
22777 do not expand if the expression is the actual in a call, because proper
22778 expansion will take place when the call itself is expanded.
22779 (Resolve_Allocator): If the context is an unchecked conversion, the
22780 allocator inherits its storage pool, if any, from the target type of
22783 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22784 Javier Miranda <miranda@adacore.com>
22786 * sem_type.adb (Add_One_Interp): If a candidate operation is an
22787 inherited interface operation that has an implementation, use the
22788 implementation to avoid spurious ambiguities.
22789 (Interface_Present_In_Ancestor): In case of concurrent types we can't
22790 use the Corresponding_Record_Typ attribute to look for the interface
22791 because it is set by the expander (and hence it is not always
22792 available). For this reason we traverse the list of interfaces
22793 (available in the parent of the concurrent type).
22794 (Interface_Present_In_Ancestor): Handle entities from the limited view
22796 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22798 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
22799 from the list of required components.
22800 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
22801 primitive procedure of a limited interface with a controlling first
22803 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
22805 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
22806 capture if it is generated in the second operand of a short-circuit
22808 Do not capture values for variables with address clauses.
22809 (Is_Object_Reference): Treat a function call as an object reference only
22810 if its type is not Standard_Void_Type.
22812 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22814 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
22815 to a variable that is statically known to be constant.

22832 Document new treatment of wide characters in max line length
22834 Remove -gnatL/-gnatZ switches, no longer used.
22835 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

23074 _withed_unit that checks if some package installed through normal with
23075 clauses has a renaming declaration of package whose limited-view is
23076 ready to be installed. This enforces the check of the rule 10.1.2 (21/2)
23077 of the current Draft document for Ada 2005.
23078 (Analyze_Context): Complete the list of compilation units that
23079 are allowed to contain limited-with clauses. It also contains
23080 checks that were previously done by Install_Limited_Context_Clauses.

23597 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
23598 longer protected objects. They have been replaced by lower-level
23599 suspension objects made up by a mutex and a condition variable (or
23600 their equivalent given a particular OS) plus some internal data to
23601 reflect the state of the suspension object.
23602 (Initialize, Finalize): Add this initialization procedure for
23603 Suspension_Object, which is a controlled type.
23604 (Finalize): Add the finalization procedure for Suspension_Object,
23605 which is a controlled type.
23607 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

23623 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
23624 set the environment task mask here.
23625 (Current_State): Add this function that returns the state of the
23627 (Set_False): Add this procedure that sets the state of the suspension
23629 (Set_True): Add this procedure that sets the state of the suspension
23630 object to True, releasing the task that was suspended, if any.
23631 (Suspend_Until_True): Add this procedure that blocks the calling task
23632 until the state of the object is True. Program_Error is raised if
23633 another task is already waiting on that suspension object.
23634 (Initialize): Add this procedure for initializing the suspension
23635 object. It initializes the mutex and the condition variable which are
23636 used for synchronization and queuing, and it sets the internal state
23638 (Finalize): Add this procedure for finalizing the suspension object,
23639 destroying the mutex and the condition variable.

23644 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
23645 which provides a low-level abstraction (using operating system
23646 primitives) for Ada.Synchronous_Task_Control.
23647 This object is made up by a mutex (for ensuring mutual exclusion), a
23648 condition variable (for queuing threads until the condition is
23649 signaled), a Boolean (State) indicating whether the object is open,
23650 and a Boolean (Waiting) reflecting whether there is a task already
23651 suspended on this object.

23803 type given in the allocator's expression is not deeper than the level
23804 of the allocator's access type.
23806 (Tagged_Membership): Modified to gives support to abstract interface
23809 * a-tags.ads, a-tags.adb (type Type_Specific_Data): Add component

23814 (Set_Access_Level): New private procedure
23815 (IW_Membership): New function. Given the tag of an object and the tag
23816 associated with an interface, evaluate if the object implements the
23818 (Register_Interface_Tag): New procedure used to initialize the table of
23819 interfaces used by the IW_Membership function.

23825 (External_Tag): Raise Tag_Error if the passed tag equals No_Tag.
23826 (Parent_Tag): Return No_Tag in the case of a root-level tagged type,
23827 and raise Tag_Error if the passed tag equalis No_Tag, to conform with
23828 Ada 2005 semantics for the new predefined function.
23830 * exp_attr.adb (Expand_N_Attribute, case Attribute_Input): Generate
23831 call to Descendant_Tag rather than Internal_Tag.
23832 (Expand_N_Attribute, case Attribute_Output): Emit a check to ensure that
23833 the accessibility level of the attribute's Item parameter is not deeper
23834 than the level of the attribute's prefix type. Tag_Error is raised if
23835 the check fails. The check is only emitted for Ada_05.
23836 (Find_Stream_Subprogram): If a TSS exists on the type itself for the
23837 requested stream attribute, use it.
23838 (Expand_N_Attribute_Reference): If the designated type is an interface
23839 then rewrite the referenced object as a conversion to force the
23840 displacement of the pointer to the secondary dispatch table.
23841 (Expand_N_Attribute_Reference, case 'Constrained): Return false if this
23842 is a dereference of an object with a constrained partial view.
23844 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
23845 type is a class-wide type, emit a run-time check that the accessibility

23852 (Make_DT): Generate a call to set the accessibility level of the
23853 tagged type in its TSD.
23854 (Make_DT): Code cleanup. The functionality of generating all the
23855 secondary dispatch tables has been moved to freeze_record_type.
23856 (Make_Abstract_Interface_DT): Minor code cleanup.
23857 (Set_All_DT_Position): Code cleanup. As part of the code cleanup
23858 this subprogram implements a new algorithm that provides the
23859 same functionality and it is more clear in case of primitives
23860 associated with abstract interfaces.
23861 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code

24116 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
24117 check on possible violation of restriction No_Direct_Boolean_Operators

25074 * styleg.adb (Check_Line_Terminator): Add check for new switch -gnatyd
25075 (check dos line terminator).
25076 (Check_Line_Max_Length): New procedure, split off from the existing
25077 Check_Line_Terminator routine. Separating this out allows -gnatyf to
25078 be properly recognized.
25080 * styleg.adb: Add ??? comment for line terminator reference
25082 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

25119 views are involved.
25121 2005-03-29 Thomas Quinot <quinot@adacore.com>
25123 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
25124 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
25125 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
25126 analyzed if expansion is disabled (which could otherwise cause spurious
25127 error messages if expansion has been disabled due to previous
25128 (unrelated) errors).
25130 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
25131 is disabled, the entity denoted by the argument is the access type
25132 itself, not an underlying record type, so there is no need to go back
25133 to the Corresponding_Remote_Type.
25135 2005-03-29 Gary Dismukes <dismukes@adacore.com>
25136 Robert Dewar <dewar@adacore.com>
25138 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
25139 expand a call to an instance of
25140 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
25141 Constructor actual of the instance. A class-wide membership
25142 check is also generated, to ensure that the tag passed to the instance
25143 denotes a type in the class.
25144 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
25145 of Name_Generic_Dispatching_Constructor.
25147 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
25148 05 unit for AI-260-02).
25150 * a-tgdico.ads: New file.
25152 * impunit.adb (Non_Imp_File_Names_05): Add entry "a-tgdico" for new

25159 * sem_ch8.adb (Find_Direct_Name): Go to root type for check of
25160 character type cases.
25161 (Analyze_Subprogram_Renaming): Add special handling for
25162 the case of renaming of stream attributes when the renaming denotes a
25163 generic formal subprogram association for an abstract formal subprogram.
25164 Check that the attribute is a primitive stream attribute (and not
25165 a class-wide stream attribute) and then rewrite the attribute name
25166 as the name of the appropriate compiler-generated stream primitive.
25168 2005-03-29 Robert Dewar <dewar@adacore.com>
25170 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to
25172 (Is_Possibly_Unaligned_Object): Correct typo that
25173 resulted in inaccurate result for unaligned scalars within records.
25175 2005-03-29 Ed Schonberg <schonberg@adacore.com>
25177 * freeze.adb (Freeze_Record_Type): If the type of the component is an
25178 itype whose parent is controlled and not yet frozen, do not create a
25179 freeze node for the itype if expansion is disabled.
25181 2005-03-29 Vincent Celier <celier@adacore.com>
25183 * make.adb (Gnatmake): Don't fail if the main project file is declared
25184 as having no Ada sources. Do not display message "no sources to
25185 compile" in quiet output.
25187 2005-03-29 Doug Rupp <rupp@adacore.com>
25189 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as
25192 2005-03-29 Robert Dewar <dewar@adacore.com>
25194 * par-ch12.adb (P_Generic): Give better msg for illegal private generic
25197 2005-03-29 Robert Dewar <dewar@adacore.com>
25199 * par-ch3.adb (P_Type_Declaration): Fix bad error recovery after
25200 missing TYPE Improve the error message generated when compiling a
25201 limited interface in Ada83 or Ada95 mode.
25203 2005-03-29 Robert Dewar <dewar@adacore.com>
25205 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
25206 rather than proceed ahead using a junk attribute name.
25208 2005-03-29 Vincent Celier <celier@adacore.com>
25210 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
25212 * prj-part.adb (Parse_Single_Project): Set the location of a project
25213 on its defining identifier, rather than on the reserved word "project".
25215 * prj-proc.adb (Expression): Adapt to the fact that default of external
25216 references may be string expressions, not always literal strings.
25217 (Recursive_Process): Set Display_Name equal to Name
25218 when Location is No_Location, that is when there is no actual file.
25219 Get the Display_Name of the project from the source, when it is not a
25221 (Process): Use the Display_Name in error messages
25223 * prj-strt.adb (External_Reference): Allow default to be string
25224 expressions, not only literal strings.
25226 2005-03-29 Vincent Celier <celier@adacore.com>
25228 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
25229 file and the reference symbol file to be the same file.
25231 2005-03-29 Thomas Quinot <quinot@adacore.com>
25233 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
25234 forbid conversion of a local access-to-subprogram type to a remote one.
25236 * sem_util.adb (Wrong_Type): For a record type that is the expanded
25237 equivalent type for a remote access-to-subprogram type, go back to the
25238 original RAS entity when displaying an error message, so the casing is
25239 the original source casing.
25241 2005-03-29 Robert Dewar <dewar@adacore.com>
25243 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
25246 2005-03-29 Ed Schonberg <schonberg@adacore.com>
25248 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
25249 subtype if code is being pre-analyzed, to prevent un-expanded
25250 references to protected formals, among others.
25251 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
25252 interpretation that can be a call, include the result of the call as a
25253 possible interpretation of the dereference.
25255 * sem_ch5.adb (Process_Bounds): Determine type of range by
25256 pre-analyzing a copy of the original range, and then analyze the range
25257 with the expected type.
25259 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
25260 with an overloaded prefix where not all interpretations yield an
25261 access to subprogram, do not rewrite node as a call.
25262 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
25263 the node as a call once the context identifies the interpretation of
25264 the prefix whose call yields the context type.
25265 (Valid_Conversion): For the case of a conversion between
25266 local access-to-subprogram types, check subtype conformance using
25267 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
25268 detailed error message.
25270 2005-03-29 Ed Schonberg <schonberg@adacore.com>
25272 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
25273 indicator, indicate that the formal can never be null.
25274 (Process_Formals): If a formal has a non_null indicator, insert the
25275 resulting subtype immediately before the enclosing subprogram decl,
25276 and not at the beginning of the corresponding declarative part, to

25755 subprograms. Adapt to change in project manager with project tree
25756 In_Tree and project node tree From_Project_Node_Tree.
25758 * prj-strt.ads, prj-strt.adb (Buffer, Buffer_Last): Global variables,
25759 to replace those that were in the private part of package Prj.
25760 Add new parameter In_Tree to designate the project node tree to most
25761 subprograms. Adapt to change in Prj.Tree with project node tree In_Tree.
25763 * prj-tree.ads, prj-tree.adb: Add new parameter of type
25764 Project_Node_Tree_Ref to most subprograms.
25765 Use this new parameter to store project nodes in the designated project
25767 (Project_Node_Tree_Ref): New type to designate a project node tree

25778 2005-03-15 Olivier Hainque <hainque@adacore.com>
25780 * s-intman-posix.adb (Notify_Exception): Adjust signature, as handler
25781 for sigactions with SA_SIGINFO set. Call
25782 __gnat_adjust_context_for_raise before raising, to perform the
25783 potentially required adjustments to the machine context for the GCC
25786 * raise.h (__gnat_adjust_context_for_raise): New prototype.
25788 * init.c (__gnat_adjust_context_for_raise) HPUX: Initial revision.
25789 Adjust PC by one in the provided machine context.
25790 (__gnat_install_handler) HPUX: Set SA_SIGINFO in the sigaction flags,
25791 so that the handler is passed the context structure to adjust prior to
25793 (__gnat_error_handler) HPUX: Adjust the signature to match what an
25794 SA_SIGINFO sigaction should look like. Call
25795 __gnat_adjust_context_for_raise before actually raising.
25796 (__gnat_adjust_context_for_raise): Default noop to help PC
25797 adjustments before raise from signal handlers.
25798 (__gnat_error_handler): Indirectly call a predicate function to
25799 determine if a condition should be resignaled or not.

25828 a-stwiun.ads, a-stwiun.adb, a-strunb.ads, a-strunb.adb: Move
25829 Realloc_For_Chunk to private part of package.
25830 New subprograms for AI-301
25832 * a-szuzti.adb, a-suteio.adb, a-swuwti.adb: Improve efficiency of
25833 Get_Line procedure.
25834 Avoid unnecessary use of Get/Set_Wide_String
25836 2005-03-15 Robert Dewar <dewar@adacore.com>
25839 * a-stunau.ads, a-stunau.adb:
25840 Change interface to allow efficient (and correct) implementation
25841 The previous changes to allow extra space in unbounded strings had
25842 left this interface a bit broken.
25844 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
25846 * g-spipat.ads, g-spipat.adb: New interface for Get_String
25847 Minor reformatting (function specs)

25881 (Set_Task_Body_Procedure): New subprogram to set this attribute.
25882 (Has_Controlled_Component): Now applies to all entities.
25883 This is only a documentation change, since it always worked to apply
25884 this to other than composite types (yielding false), but now this is
25886 Update documentation on Must_Be_Byte_Aligned for new spec
25888 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
25889 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
25890 uses of the Access_Disp_Table attribute to reference the first dispatch
25891 table associated with a tagged type. As
25892 part of the implementation of abstract interface types,
25893 Access_Disp_Table has been redefined to contain a list of dispatch
25894 tables (rather than a single dispatch table).
25895 Similarly, upgrade all the references to Tag_Component by the
25896 new attribute First_Tag_Component.
25897 (Find_Inherited_TSS): Moved to exp_tss.
25898 Clean up test in Expand_N_Object_Declaration for cases
25899 where we need to do a separate assignment of the initial value.
25900 (Expand_N_Object_Declaration): If the expression in the
25901 declaration of a tagged type is an aggregate, no need to generate an
25902 additional tag assignment.
25903 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
25905 Bit packed array ops are only called if operands are known to be
25907 (Component_Equality): When returning an N_Raise_Program_Error statement,
25908 ensure that its Etype is set to Empty to avoid confusing GIGI (which
25909 expects that only expressions have a bona fide type).
25910 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
25911 determine the amount of data to be copied.
25913 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
25914 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
25915 INTERFACE_TYPE_DEFINITION ::=

25917 [AND interface_list]
25919 * par-ch3.adb (P_Type_Declaration): Modified to give support to

25926 messages by the correct RENAMES (quotes removed).
25928 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
25929 attribute First_Tag_Component.

25938 derived type definition nodes.
25939 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
25940 (Task_Present, Set_Task_Present): New subprogram.
25941 (Task_Body_Procedure): Removed.
25942 (Set_Task_Body_Procedure): Removed.
25943 These subprogram have been removed because the attribute
25944 Task_Body_Procedure has been moved to the corresponding task type
25945 or task subtype entity to leave a field free to store the list
25946 of interfaces implemented by a task (for AI-345)
25947 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
25948 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
25949 expression flag Do_Range_Check
25950 (Exception_Junk): Change to Flag7 to accomodate above change
25951 (Box_Present, Default_Name, Specification, Set_Box_Present,
25952 Set_Default_Name, Set_Specification): Expand the expression
25953 "X in N_Formal_Subprogram_Declaration" into the corresponding
25954 two comparisons. Required to use the csinfo tool.

25957 "with string" given.
25959 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
25962 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
25965 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
25966 attribute Task_Body_Procedure rather than the old semantic field that
25967 was available in the task_type_declaration node.
25969 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
25970 interface type definitions.
25971 (P_Formal_Derived_Type_Definition): Modified to handle the list of
25974 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
25975 task type declaration.
25976 (P_Protected): Modified to handle the list of interfaces in a
25977 protected type declaration.
25979 2005-03-15 Doug Rupp <rupp@adacore.com>
25980 Vincent Celier <celier@adacore.com>
25982 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
25983 (Gen_Output_File_C): Likewise.
25984 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
25986 2005-03-15 Thomas Quinot <quinot@adacore.com>
25988 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
25989 is an N_Raise_Constraint_Error node, create a new copy of it without
25990 going through a call to Duplicate_Subexpr.
25992 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
25993 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
25994 Nicolas Setton <setton@adacore.com>
25995 Ed Schonberg <schonberg@adacore.com>
26001 * decl.c (gnat_to_gnu_field): Reject aliased components with a
26002 representation clause that prescribes a size not equal to the rounded
26003 size of their types.
26004 (gnat_to_gnu_entity, case E_Component): Always look at
26005 Original_Record_Component if Present and not the entity.
26006 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
26007 of tagged extension types by not making field for components that are
26009 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
26010 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
26011 expression to the type of the object when the object is constant.
26012 Reverse defer_debug_incomplete_list before traversing it, so that trees
26013 are processed in the order at which they were added to the list. This
26014 order is important when using the stabs debug format.
26015 If we are deferring the output of debug information, also defer this
26016 output for a function return type.
26017 When adding fields to a record, prevent emitting debug information
26018 for incomplete records, emit the information only when the record is
26020 (components_to_record): New parameter defer_debug.
26021 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
26022 (gnat_to_gnu_field_decl): New function.

26024 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
26025 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
26026 No longer update discriminants to not be a COMPONENT_REF.
26027 (copy_alias_set): Strip padding from input type; also handle
26028 unconstrained arrays properly.
26030 * gigi.h (write_record_type_debug_info): New function.
26031 Convert to use ANSI-style prototypes. Remove unused
26032 declarations for emit_stack_check, elab_all_gnat and
26033 set_second_error_entity.
26034 (gnat_to_gnu_field_decl): New decl.
26036 * utils.c (write_record_type_debug_info): New function.

26040 (update_pointer_to): Fix pasto.
26041 (convert) <UNION_TYPE>: Accept slight type variations when
26042 converting to an unchecked union type.
26044 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
26045 replace the N_Freeze_Entity with a null statement.
26047 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
26048 within a constrained subcomponent of an enclosing record, place the
26049 freeze nodes in the scope stack entry for the enclosing record.
26050 (Undelay_Type): New Subprogram.
26051 (Set_Small_Size): Pass T, the type to modify; all callers changed.
26052 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
26053 within records; allow them to have freeze nodes if their base types
26056 * exp_util.adb (Remove_Side_Effects): Properly test for
26057 Expansion_Delayed and handle case when it's inside an
26058 N_Qualified_Expression.
26060 * sem_ch3.adb (Derived_Type_Declaration): New predicate
26061 Comes_From_Generic, to recognize accurately that the parent type in a
26062 derived type declaration can be traced back to a formal type, because
26063 it is one or is derived from one, or because its completion is derived
26065 (Constrain_Component_Type): If component comes from source and has no
26066 explicit constraint, no need to constrain in in a subtype of the
26068 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
26069 Minor change to propagate Is_Ada_2005 flag
26071 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
26072 Expansion_Delayed is False.
26073 (assoc_to_constructor): Ignore fields that have a
26074 Corresponding_Discriminant.
26075 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
26076 function returns "by target", dereference the target pointer using the
26077 type of the actual return value.
26078 <all>: Be prepared for a null gnu_result.
26079 (processed_inline_subprograms): Check flag_really_no_inline
26080 instead of flag_no_inline.
26081 (set_second_error_entity): Remove unused function.

26086 2005-03-15 Robert Dewar <dewar@adacore.com>
26087 Ed Schonberg <schonberg@adacore.com>
26088 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26090 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
26091 Must_Be_Byte_Aligned for cases where we do not need to use a
26092 System.Pack_nn unit.
26094 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
26096 Needed now that we do some processing for IN parameters as well. This
26097 may well fix some unrelated errors.
26098 (Expand_Call): Handle case of unaligned objects (in particular those
26099 that come from packed arrays).
26100 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
26101 renamed entity is an inherited operation, re-expand the call using the
26102 original operation, which is the one to call.
26103 Detect attempt to inline parameterless recursive subprogram.
26104 (Represented_As_Scalar): Fix to work properly with private types
26105 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
26106 accurate estimate. Yields True in far fewer cases than before,
26107 improving the quality of code that depends on this test.
26109 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
26110 over both visible and private declarations to remove them from tree,
26111 and mark subprograms declared in package as eliminated, to prevent
26112 spurious use in subsequent compilation of generic units in the context.
26114 * exp_util.ads: Minor cleanup in variable names
26116 * sem_eval.ads, sem_eval.adb: Minor reformatting
26117 (Compile_Time_Known_Bounds): New function
26119 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26121 * exp_ch7.adb (Convert_View): Use base types of underlying types when
26122 determining whether an unchecked conversion is needed for the argument
26123 of an initialization call.
26125 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26127 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
26128 that appears in the instantiation rather than the internal subtype
26129 generated in the wrapper package, to avoid anomalies in gigi when the
26130 target is derived from a private type whose full view is an access type.
26132 2005-03-15 Robert Dewar <dewar@adacore.com>
26134 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
26136 Add documentation to replace the use of this flag
26137 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
26140 2005-03-15 Thomas Quinot <quinot@adacore.com>
26142 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
26143 here from exp_attr so it can be shared between exp_attr and exp_dist.
26144 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
26145 all TSS names, not a subset thereof, and the previous name introduced
26146 an unnecessarily confusion that a distinction might exist between
26147 "OK" TSS names and some "not OK" TSS names.
26149 2005-03-15 Doug Rupp <rupp@adacore.com>
26151 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
26154 2005-03-15 Pascal Obry <obry@adacore.com>
26155 Eric Botcazou <ebotcazou@adacore.com>
26159 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
26160 when IN_RTS. This is to work around a bootstrap path problem.
26162 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
26163 table and pass it to __gnat_install_SEH_handler().
26164 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
26166 * lang.opt: Fix specification of -fRTS=.
26168 2005-03-15 Doug Rupp <rupp@adacore.com>
26169 Bernard Banner <banner@adacore.com>
26170 Vincent Celier <celier@adacore.com>
26171 Arnaud Charlet <charlet@adacore.com>
26174 This change works fine when gnatlib is built from the gcc directory,
26175 but does not work when using the libada Makefile, since GCC_FOR_TARGET
26176 is not passed to ada/Makefile.in, so more work is needed by a
26177 Makefile/configure expert.
26179 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
26180 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
26181 Setup gnatlink switch -M for x86_64 linux, as it is already setup
26183 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
26184 Run ranlib on libgccprefix.a
26185 Define PREFIX_OBJS for Darwin, to build libgccprefix.
26186 (ADA_INCLUDE_SRCS): Split Ada packages.
26188 2005-03-15 Robert Dewar <dewar@adacore.com>
26190 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
26192 * impunit.adb: Add GNAT.UTF_32
26194 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
26196 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
26197 now uses GNAT.UTF_32).
26199 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
26200 capabilities for categorizing characters using Unicode categories
26202 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26204 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
26205 instantiation that has been rewritten as a package body, retrieve spec
26206 to generate proper name for implicit_with_clause.
26207 (Install_Parents): Recognize a parent that is an instantiation but has
26208 been rewritten as a package declaration during analysis.
26210 2005-03-15 Javier Miranda <miranda@adacore.com>
26211 Ed Schonberg <schonberg@adacore.com>
26213 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
26214 parameter reported some error we immediately return. This improves the
26215 behaviour of the frontend in case of errors.
26216 (Install_Parent, Remove_Parent): Introduce new flag
26217 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
26218 ancestor of a generic child unit, when the child is being instantiated.
26219 (Inline_Instance_Body): If we are compiling the private
26220 part or the body of a child unit, restore the proper visibility of the
26221 parents after compiling the instance body.
26223 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26224 Javier Miranda <miranda@adacore.com>
26227 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
26228 of a private type, in which case it is underlying_type that denotes
26229 the proper task. Also modified to use the new entity attribute
26230 that is directly available in the task type and task subtype entities
26231 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
26232 arrays when other dimensions than the first are constrained by
26233 discriminants of an enclosing record.
26234 (Insert_Explicit_Dereference): If the prefix is an indexed component or
26235 a combination of indexed and selected components, find ultimate entity

26720 (which is now a subtype).
26721 Char_Literal_Value field is now a Uint
26723 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
26724 pointer to the base of the dispatch table.
26725 Minor changes to comments.
26726 (Controlling_Type): New function for determining the tagged type
26727 associated with a tagged primitive subprogram.
26728 (Expand_Dispatching_Call): Add support for a controlling actual that is
26729 directly a value of type Ada.Tag rather than a tagged object.
26731 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
26732 describing the new layout.
26733 (Dispatch_Table): The expander computes the actual array size, allocates
26734 the Dispatch_Table record accordingly, and generates code that displaces
26735 the base of the record after the Typeinfo_Ptr component. The access to
26736 these components is done by means of local functions.
26737 (Offset_To_Top): New function.
26738 (Typeinfo_Ptr): New function.
26739 (Get_TSD): Modified to access the new position of the TSD.
26740 (Set_TSD): Modified to save the TSD in its new position.
26742 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
26743 case of formal abstract subprograms. Add check and message for -gnat05.
26746 * sem_ch12.adb: Add with and use for Sem_Disp.

26748 N_Formal_Subtype_Declaration (which is now a subtype).
26749 (Set_Analyzed_Formal): Minor changes from "=" to "in" for uses of
26750 N_Formal_Subtype_Declaration (which is now a subtype).
26751 (Analyze_Formal_Subprogram): Add handling for
26752 N_Formal_Abstract_Subprogram, marking the formal as abstract and
26753 dispatching, setting the controlling status of the formal parameters
26754 and result, and issuing an error if there is no controlling type for
26755 the formal subprogram.
26756 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
26757 which is an unclean use of that field, we set the new field
26758 Corresponding_Formal_Spec to make the formal subprogram available to
26759 processing in Analyze_Subprogram_Declaration.
26760 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
26761 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
26762 Constrained, so that it is is does not statically match its anonymous
26765 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
26766 abstract formal subprograms in error check for functions returning
26767 abstract types. Set scope of new designator for
26768 a parameterless subprogram, so that it is available when checking the
26769 body for nested subprograms, before full analysis of said body.
26770 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
26771 subprogram only if inner one comes from source.
26772 (Analyze_Function_Call): If the call is given in object notation, the
26773 analysis of the name rewrites the node and analyzes it with the proper
26774 argument list. After analyzing the name, if the call has been rewritten
26775 and the result type is set, no further analysis is needed.
26776 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
26777 mark in function specification, in a context where the formals are
26778 visible and hide outer homographs.
26780 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
26781 as the tagged type for the cases of abstract formal subprograms and
26782 renamings of those. Clean up spec comments.
26783 (Check_Dispatching_Context): Add error message to indicate "abstract
26784 procedure", covering the case of a call to a formal abstract procedure
26785 that has statically tagged operands.
26786 (Check_Dispatching_Call): Check for the case of an actual given by
26787 a tag-indeterminate function call whose type is an ancestor of the
26788 containing call's associated tagged type. This situation can occur
26789 for inherited primitives with function defaults. In this case we
26790 use the tagged type's tag directly as the controlling argument for
26792 (Expand_Call): Name change on call to Expand_Dispatch_Call.
26794 * sprint.adb (Sprint_Node_Actual): Split
26795 N_Formal_Subprogram_Declaration into two alternatives for the new
26796 cases N_Formal_Abstract_Subprogram_Declaration and
26797 N_Formal_Concrete_Subprogram_Declaration.
26798 Char_Literal_Value field is now a Uint.
26800 * trans.c: Get rid of junk Uint2 reference.
26801 Char_Literal_Value field is now a Uint.
26802 (gnat_to_gnu, case N_Aggregate): Check TYPE_UNCHECKED_UNION_P.
26803 (gigi): Correct third arg to gimplify_body.
26805 * ada-tree.h: (TYPE_UNCHECKED_UNION_P): New flag.
26806 (TYPE_LANG_FLAG_0): Check for record or union.

26810 * uintp.h, uintp.ads, uintp.adb: Add new routines UI_To_CC and
26813 * widechar.ads, widechar.adb (Is_UTF_32_Non_Graphic): New function
26814 Add full UTF-32 support
26815 Char_Code is now 32 bits
26817 * sinput.ads, sinput.adb (Skip_Line_Terminators): Extend to deal with
26818 wide character UTF_32 line terminators.
26819 Initialize Main_Source_File to avoid error when no main
26822 * errout.adb (Finalize): Do not check Num_SRef_Pragmas
26823 (Main_Source_File) when no main source has been loaded, to avoid
26826 2005-02-09 Robert Dewar <dewar@adacore.com>
26828 * a-strunb.ads, a-strunb.adb: Add missing pragma Ada_05 statements

26842 a-wtedit.adb, a-wtedit.adb, a-wtedit.ads, a-wttest.adb,
26843 a-wttest.ads, a-strmap.ads, a-strmap.adb, a-stwima.adb,
26844 a-stwima.ads: Minor reformatting.
26846 2005-02-09 Doug Rupp <rupp@adacore.com>
26847 Thomas Quinot <quinot@adacore.com>
26849 * adaint.c, adaint.h
26850 [VMS] (to_ptr32): New function.

26855 [VMS] (#define fork()): Remove since unneccessary.
26856 (__gnat_set_close_on_exec): New routine to support
26857 GNAT.OS_Lib.Set_Close_On_Exec.
26859 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
26860 the parent side as close-on-exec so that they are not inherited by the
26863 * g-os_lib.ads, g-os_lib.adb (Set_Close_On_Exec): New subprogram to
26864 set or clear the FD_CLOEXEC flag on a file descriptor.
26866 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
26867 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26871 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
26872 on the field if Pragma Component_Alignment (Storage_Unit).
26873 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
26874 side-effects as if it were a constant; also make SAVE_EXPR to protect
26876 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
26878 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
26879 (components_to_record): Test it.
26880 Fix improper usage of REFERENCE_CLASS_P.
26882 * utils2.c (build_binary_op, case MODIFY_EXPRP): Treat UNION_TYPE as
26885 * utils2.c: Minor reformatting.
26887 * utils.c (convert, case UNION_TYPE): Check TYPE_UNCHECKED_UNION;

26890 * utils.c (gnat_pushdecl): Set TREE_NO_WARNING.
26892 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26894 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
26895 component of an array of arrays in an assignment context, and the
26896 aggregate has component associations that require sliding on
26897 assignment, force reanalysis of the aggregate to generate a temporary
26898 before the assignment.
26899 (Must_Slide): Make global to the package, for use in Gen_Assign.
26901 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26903 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
26904 unchecked union with no inferable discriminants, return a
26905 Raise_Program_Error node, rather than inserting it at the point the
26907 (Expand_Record_Equality, Component_Equality): Handle properly the case
26908 where some subcomponent is an unchecked union whose generated equality
26909 code raises program error.
26911 2005-02-09 Doug Rupp <rupp@adacore.com>
26913 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

26917 Arnaud Charlet <charlet@adacore.com>
26919 * init.c (__gnat_initialize): Add a new parameter eh which contains the
26920 address of the exception registration. The Win32 version of this
26921 routine calls __gnat_install_SEH_handler() to initialize the SEH
26922 (Structured Exception Handling) handler.
26923 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
26924 SEH (Structured Exception Handling) now.
26925 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
26926 (__gnat_initialize for ppc-vxworks): Adjust comments and the
26927 preprocessor condition protecting the call to the extra eh setup
26928 subprogram, which is only available for the ppc target.
26929 (__gnat_clear_exception_count): replaced reference to
26930 variable taskIdCurrent by call to taskIdSelf(), cleaner.
26932 * seh_init.c: New file.
26934 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
26935 (GNATBIND_OBJS): Idem.
26937 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
26938 routine takes a new parameter (a pointer to the exception registration
26939 for the SEH (Structured Exception Handling) support.
26941 * raise.h: (__gnat_install_SEH_handler): New prototype.
26942 Update copyright notice.
26944 * s-tassta.adb (Task_Wrapper): Declare the exception registration
26945 record and initialize it by calling __gnat_install_SEH_handler.
26947 2005-02-09 Vincent Celier <celier@adacore.com>
26949 * make.adb (Gnatmake): Do not fail when the main project has no object

26955 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
26956 [VMS]: Add translations for g-enblsp.adb.
26958 * s-asthan-vms.adb: Removed.
26959 * s-asthan-vms-alpha.adb: Added.
26961 2005-02-09 Pascal Obry <obry@adacore.com>
26963 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.
26964 (LIBGNAT_OBJS): Add seh_init.o.
26966 2005-02-09 Arnaud Charlet <charlet@adacore.com>
26969 * Makefile.in: Link all gnat tools with -static-libgcc, since
26970 -shared-libgcc is now used by default on some systems (e.g. linux with
26972 Remove references to Makefile.prolog/generic, no longer used.
26974 2005-02-09 Vincent Celier <celier@adacore.com>
26976 * prj-makr.adb (Process_Directory): Put file name in canonical case
26977 before matching against the patterns.
26978 If gnatname has been invoked as <prefix>-gnatname
26979 then invoke the compiler as <prefix>-gcc, not just "gcc".
26981 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26983 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
26984 with expansion disabled. The actual subtype is needed among other
26985 places when the selected component appears in the context of a loop
26986 bound, and denotes a packed array.
26987 (Operator_Check): Always use the first subtype in the
26988 error message, to avoid the appearance of internal base types.
26989 (Transform_Object_Operation): Copy each actual in full
26990 to the parameter associations of the constructed call, rather than
26991 using the shallow copy mechanism of New_Copy_List. This ensures that
26992 the chaining of named associations is done properly.
26993 (Complete_Object_Operation): Rewrite node, rather than
26994 replacing it, so that we can trace back to the original selected
26997 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
26998 and calls that use object notation, if the called function is not
26999 declared in a withed unit, place the elaboration constraint on the
27000 unit in the context that makes the function accessible.
27001 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
27002 imposes an elaboration constraint between two packages.
27004 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27006 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
27007 views of a private type after handling its private dependents, to
27008 maintain proper stack discipline between entry and exit from the
27011 2005-02-09 Cyrille Comar <comar@adacore.com>
27013 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

27018 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
27019 fields for foreign threads.
27021 2005-02-09 Doug Rupp <rupp@adacore.com>
27023 * s-vaflop.adb: Add pragma Warnings (Off) to eliminate infinite
27024 recursion warnings when compiled with -gnatdm.
27026 2005-02-09 Robert Dewar <dewar@adacore.com>
27028 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
27029 Slight fix to documentation of -gnaty with no parameters
27031 * xr_tabls.ads: Add ??? comment for missing overall comment
27033 * xsinfo.adb: Make default file name be sinfo.h, since this is what
27034 we now use by default.
27036 * xsnames.adb: Adjust end of file test to look for five space followed
27037 by '#' instead of six spaces. The format of xsnames.adb was modified
27038 in the last update.
27040 * a-numeri.ads: Add reference to AI-388 for greek letter pi
27043 * clean.adb: Minor reformatting.
27045 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
27046 gnatname.adb: Minor reformatting
27047 Add 2005 to copyright output when utility is run
27049 * csets.adb: Eliminate obsolete comment
27051 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
27054 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
27056 2005-02-09 Sergey Rybin <rybin@adacore.com>
27058 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
27059 the difference between compact and incompact layout and add the record
27060 representation clause to the example illustrating different layouts.
27061 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
27062 component clauses").
27064 2005-02-09 Florian Villoing <villoing@adacore.com>
27066 * gnat_ugn.texi: Fix typos.
27067 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
27069 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
27070 in the generated documentation.
27072 2005-02-09 Arnaud Charlet <charlet@adacore.com>
27074 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
27076 Update linker wrapper when linking with non GNU C++.
27078 2005-02-09 Pascal Obry <obry@adacore.com>
27081 Document the procedure to debug the DllMain routine on Windows.
27082 Add note about -funwind-tables and mixed Ada and C/C++ programming in
27084 Document new BIND qualifer /RETURN_CODES=VMS.
27086 2005-02-09 Ben Brosgol <brosgol@adacore.com>
27088 * gnat_ugn.texi: Wordsmithing of "GNAT and Libraries" chapter
27089 Edited gnatmetric chapter

27104 * s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
27105 from the VxWorks kernel) that is needed for getting the active
27106 priority of the different tasks.
27108 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
27109 Use a pragma Elaborate_Body in the spec file instead.
27110 Noticed by code reading.
27112 2005-02-09 Thomas Quinot <quinot@adacore.com>
27114 * exp_util.ads: Minor correction in comment.
27116 2005-02-09 Arnaud Charlet <charlet@adacore.com>
27118 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
27119 since this procedure is now too complex to be worth inlining.
27121 2005-02-09 Richard Henderson <rth@redhat.com>
27123 * utils.c (gnat_define_builtin): Remove.
27124 (gnat_install_builtins): Use build_common_builtin_nodes.

27762 TYPE_SIZE_UNIT of result type if SIZE is not specified.
27763 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
27764 of a bitfield, which we know is useless and causes trouble because of
27765 alignment implications.

27774 "no bitfield creation", to be used by make_aligning_type. Don't
27775 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
27776 fields claimed addressable still have to be bitfields. Use
27777 value_factor_p instead of a raw binop construction to check for the
27778 position's alignment.

27785 Ed Schonberg <schonberg@adacore.com>
27787 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
27788 with an implicit dereference as its prefix, use
27789 Insert_Explicit_Dereference instead of merely rewriting the prefix into
27790 an explicit dereference. This ensures that a reference to the original
27791 prefix is generated, if appropriate.
27793 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
27794 dereference is rewritten to an explicit one, generate a reference to
27795 the entity denoted by its prefix using the original prefix node, so
27796 the dereference can be properly recorded as a read of the denoted
27797 access value, if appropriate.
27799 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
27800 emitting 'assigned but never read' warning on a variable on the basis

27813 This deals with the case where the pragma Import specified
27814 an external name, to be handled by the back end.
27816 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
27817 subprogram which is Imported with convention Intrinsic if an
27818 External_Name argument is specified.
27819 (Process_Import_Or_Interface): Properly diagnose link name argument.
27820 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

27876 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
27877 and the Has_Pragma_Unreferenced flag for each formal before analyzing
27878 the body, to ensure that warnings are properly emitted for each accept
27879 statement of a given task entry.

27909 2004-12-07 Thomas Quinot <quinot@adacore.com>
27911 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
27912 used to record an implicit dereference as a read operation on its
27913 prefix when operating under -gnatc. Necessary to avoid spurious
27914 'variable assigned but never read' warnings in that mode.
27915 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
27916 is a non-overloaded implicit dereference, call the above subprogram to
27917 ensure proper recording of references.
27919 2004-12-07 Gary Dismukes <dismukes@adacore.com>
27921 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

27971 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
27972 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
27973 and -eit to -ept. Added qualifier
27974 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
27976 2004-11-27 Andreas Schwab <schwab@suse.de>
27978 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
27980 2004-11-25 Arnaud Charlet <charlet@adacore.com>
27982 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
27983 internal implementation unit GNAT.Sockets.Thin,
27984 as their usage for sockets is non-portable (using the read and write
27985 functions from the system runtime library is fine on UNIX but won't
27986 work under Windows).

28044 list of arguments in there.
28046 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
28047 corresponding objects exported by a-exexpr, instead of hardcoded dummy
28050 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
28051 others_decl and all_others_decl instead of hardcoded dummy addresses
28052 to represent "others" and "all others" choices, which is cleaner and
28053 more flexible with respect to the possible eh pointer encoding policies.
28055 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
28056 (process_attributes): Account for the naming change of the "args"
28057 attribute list entry component.

28060 cumulating attributes for different entities into a single list.
28061 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
28062 attributes for the current entity and propagate first subtype
28063 attributes to other subtypes.
28064 <E_Procedure>: Attribute arguments are attr->args and not
28065 attr->arg any more.
28066 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
28067 argument provided, as this is what GCC expects. Use NULL_TREE instead

28109 replaced with calls to Get_Library_Unit_Name_String. Previously there
28110 were several instances of the same code in different locations in the
28111 compiler; this checkin completes the replacement of all of these
28112 instances with calls to a common subprogram.
28113 Minor reformatting.

28147 nodes are improperly shared.
28149 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
28150 pragmas to Exp_Prag, which is more appropriate.

28157 to the context type.
28158 Use new Make_String_Literal function with string.
28159 (Get_Stream_Convert_Pragma): New function, replaces the use of
28160 Get_Rep_Pragma, which had to be kludged to work in this case.
28162 * freeze.adb: Use new Has_Rep_Pragma function
28164 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
28165 function with string.

28200 iteration_scheme of a loop.
28202 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
28203 bounds that may contain functions calls, to prevent memory leaks when
28204 the bound contains a call to a function that uses the secondary stack.
28205 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
28206 generate temporaries for loop bounds that might contain function calls
28207 that require secondary stack and/or finalization actions.
28209 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
28210 selected component and the selector is overloadable (not just a
28211 function) treat as function call, Analyze_Call will disambiguate if
28213 (Analyze_Selected_Component): Do not generate an actual subtype for the
28214 selected component if expansion is disabled. The actual subtype is only
28215 needed for constraint checks.
28216 (Analyze_Allocator): If restriction No_Streams is set, then do
28217 not permit objects to be declared of a stream type, or of a
28218 composite type containing a stream.
28220 * restrict.ads: Remove the a-stream entry from Unit_Array, since
28221 No_Streams no longer prohibits with'ing this package.
28223 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
28224 discriminants, but the parent base has unknown discriminants, there is
28225 no discriminant constraint to inherit. Such a discrepancy can arise
28226 when the actual for a formal type with unknown discriminants is a
28227 similar private type whose full view has discriminants.
28228 (Analyze_Object_Declaration): If restriction No_Streams is set, then
28229 do not permit objects to be declared of a stream type, or of a
28230 composite type containing a stream.
28232 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28234 * exp_dbug.ads: Update documentation to reflect simpler encoding for
28235 protected operations.
28237 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
28238 generated name, it complicates decoding in gdb and hinders debugging
28239 of protected operations.
28240 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
28241 flag for the protected entry barrier function.
28242 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
28243 flag for the protected entry function.
28245 2004-11-18 Nicolas Setton <setton@adacore.com>
28247 * expect.c: Define __unix__ when __APPLE__ is defined.
28249 * Makefile.in: Inform the value of the variable GMEM_LIB in the
28250 Darwin-specific section.
28252 * lang-specs.h: Change the placement of the %1 marker.
28253 Works around the fact that gcc adds -fPIC by default under Darwin.
28255 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28257 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
28258 type of the object with the packed array type, set the Analyzed flag
28259 on the object if it is an entity or simple indexed component, to avoid
28260 spurious type errors.
28262 2004-11-18 Gary Dismukes <dismukes@adacore.com>
28264 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
28265 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
28266 separate line from the version message.
28268 2004-11-18 Ed Falis <falis@adacore.com>
28270 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
28272 (init_float): Eliminate initialization of floating point status for
28273 AE653. The instructions have no effect for vThreads.
28275 2004-11-18 Vincent Celier <celier@adacore.com>
28277 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
28278 gnatbind is invoked with -shared.
28280 2004-11-18 Jose Ruiz <ruiz@adacore.com>
28282 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
28283 for Detect_Blocking which is redundant with the check done within the
28284 procedure Protected_Single_Entry_Call.
28285 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
28286 Detect_Blocking which is redundant with the check done within the
28287 procedure Protected_Single_Entry_Call.
28289 2004-11-18 Vincent Celier <celier@adacore.com>
28291 * makegpr.adb (Compile): Put the compiling switches (in package
28292 Compiler and on the command line) immediately after "-c", instead of
28293 at the end of the command line invocation of the compiler, when
28294 compiling a non-Ada file.
28295 (Build_Global_Archive): When there is no need to rebuild the archive,
28296 set Global_Archive_Exists, so that the archive is passed to the linker
28299 2004-11-18 Robert Dewar <dewar@adacore.com>
28300 Sergey Rybin <rybin@adacore.com>
28303 Remove extra paren check from list of checks for redundant constructs
28304 Add documentation of new -gnatyx style check (check extra parens)
28305 Remove paragraph about gnatelim debug options.
28307 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
28308 objects rather than forbidding dependencies on the package Ada.Streams.
28310 * sinfo.ads: Add ??? note that we should document pragmas passed to
28313 * g-expect.ads: Fix a few typos in the comments.
28315 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
28317 * misc.c (gnat_handle_option): Use %< and %> for quoting in
28320 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
28322 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
28324 2004-11-07 Andreas Schwab <schwab@suse.de>
28326 * Makefile.in (install-gnatlib): Remove spurious hyphen.
28328 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
28331 * Makefile.in (darwin): Set soext to .dylib.
28333 2004-10-26 Vincent Celier <celier@gnat.com>
28334 Thomas Quinot <quinot@act-europe.fr>
28336 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
28337 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
28338 there is no use of GNAT.Sockets.Constants.
28339 Remove remaining pragma Import for C_Write
28340 Remove C_Read and C_Write from internal implementation unit
28341 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
28342 the read and write functions from the system runtime library is fine
28343 on UNIX but won't work under Windows).
28345 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
28346 (Check_Selector): Use C_Recv instead of C_Read.
28347 Selectors are the GNAT.Sockets abstraction to perform a select()
28348 call on a set of descriptors. To allow abortion of an ongoing
28349 select operation, some data is written to a dedicated socket that
28350 is always monitored.
28351 Under Windows, the write and read library functions cannot operate
28352 on sockets, so we need to use send and recv instead, which is portable
28353 across all supported platforms.
28355 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
28356 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
28357 (using the read and write functions from the system runtime library is
28358 fine on UNIX but won't work under Windows).
28360 2004-10-26 Nicolas Setton <setton@act-europe.fr>
28362 * mlib-tgt-darwin.adb: New file.
28364 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
28365 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
28366 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
28367 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
28370 * Makefile.in: Add support for building shared libraries under Darwin.
28371 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
28372 the low level EH init subprogram to be called from __gnat_initialize.
28374 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
28375 indicates which options to pass to the archive indexer.
28377 * mlib-utl.adb: Add support for calling ranlib with additional
28378 options. This is needed for instance under Mac OS X.
28379 (Ranlib_Options): New global variable, used to store the potential
28380 options to pass to ranlib.
28381 (Ar): Use Ranlib_Options when spawning ranlib.
28382 (Initialize): Set the value of ranlib option.
28384 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
28386 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
28387 instead of 8K, to reflect the real potential needs for stack-checking
28390 2004-10-26 Pascal Obry <obry@gnat.com>
28392 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
28394 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
28395 Windows only the initial thread stack size can be set so it is good to
28396 start we a low stack size.
28397 The OS will adjust the size as needed.
28399 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
28400 Nicolas Setton <setton@act-europe.fr>
28402 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
28403 "__unix__" instead of "unix".
28404 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
28405 sections were just mistakenly ignored. The former is
28406 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
28407 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
28408 of hpux. This prevents an unwanted definition of the symbol
28409 convert_addresses in adaint.o.
28411 2004-10-26 Gary Dismukes <dismukes@gnat.com>
28413 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
28414 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
28416 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28418 * a-filico.ads, a-filico.adb: fix incorrect header.
28420 2004-10-26 Javier Miranda <miranda@gnat.com>
28422 * a-ststio.ads: Fix typo in identifier
28424 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28426 * sem_ch4.adb: Minor reformatting.
28428 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28430 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
28431 enabled, check the result of unary and binary operations when the
28432 expression is the right-hand side of an assignment.
28434 2004-10-26 Vincent Celier <celier@gnat.com>
28436 * clean.adb (Delete): Do not output warnings when in quiet output and
28437 not in verbose mode.
28438 (Force_Deletions): New Boolean flag, defaulted to False
28439 (Delete): Only delete a file if it is writable, and when
28440 Force_Deletions is True.
28441 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
28442 (Usage): Line for new switch -f
28443 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
28446 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
28448 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
28449 JM type only if its size matches that of the wrapper. When a size is
28450 prescribed and the field is not aliased, remove the wrapper of a JM
28451 type only if the size is not greater than that of the packed array.
28452 (gnat_to_gnu_entity): Change the extension of packed array wrappers
28455 2004-10-26 Geert Bosch <bosch@gnat.com>
28457 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
28458 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
28459 (Pred): Implement in terms of Succ.
28461 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28463 * exp_aggr.adb (Safe_Component): An aggregate component that is an
28464 unchecked conversion is safe for in-place use if the expression of the
28465 conversion is safe.
28466 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
28467 be expandable in place even if the aggregate does not come from source.
28468 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
28469 designated object of an allocator in place, rather than building it
28470 first on the stack. The previous scheme forces a full copy of the array,
28471 and may be altogether unsusable if the size of the array is too large
28472 for stack allocation.
28474 2004-10-26 Robert Dewar <dewar@gnat.com>
28476 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
28477 compares if the component is atomic.
28479 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
28480 array assignment if the component type is atomic.
28482 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28483 Eric Botcazou <ebotcazou@act-europe.fr>
28485 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
28486 is aliased and is a by_reference type, do not pass by copy.
28487 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
28488 detect whether the call is in the right side of an assignment or
28489 the expression of an object declaration. Recurse on component
28490 association within aggregates.
28491 Call it in the condition that determines whether the temporary is
28492 necessary for correct stack-checking.
28494 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28496 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
28497 RACW_Type, used in the PolyORB version.
28498 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
28499 version and the GARLIC version.
28501 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
28502 Rename RCI_Info to RCI_Locator for better consistency between the
28503 GARLIC and PolyORB versions of the distributed systems annex.
28504 (DSA_Implementation_Name): This enumeration lists the possible
28505 implementations of the Partition Communication Subsystem for the
28506 Distributed Systems Annex (DSA). The three available implementations
28507 are the dummy stub implementation (No_DSA), and two versions based on
28508 two different distribution runtime libraries: GARLIC and PolyORB. Both
28509 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
28511 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
28514 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
28515 between the GARLIC and PolyORB versions of the distributed systems
28517 Remove RE_Unbounded_Reclaim_Pool since it is unused.
28519 2004-10-26 Gary Dismukes <dismukes@gnat.com>
28521 * gnat1drv.adb: Suppress calling the back end when
28522 Frontend_Layout_On_Target is true.
28524 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28526 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
28527 Set_Read_Only): New subprograms.
28528 These new routines allow the user to set or unset the Owner execute
28529 and Owner write permission flags on a file.
28531 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
28532 GNAT.OS_Lib.Set_Executable instead of rolling our own.
28534 2004-10-26 Matthew Gingell <gingell@gnat.com>
28536 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
28538 2004-10-26 Pascal Obry <obry@gnat.com>
28540 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
28541 memory before the faulting page we properly test the process read
28542 access for this address using appropriate Win32 routine.
28543 (HPUX sections): guard with "__hpux__" instead of "hpux".
28545 2004-10-26 Robert Dewar <dewar@gnat.com>
28547 * lib-xref.adb (Generate_Reference): Don't complain about reference to
28548 entry parameter if pragma Unreferenced set, since we do not properly
28549 handle the case of multiple parameters.
28551 2004-10-26 Vincent Celier <celier@gnat.com>
28553 * prj-env.adb: (Contains_ALI_Files): New Boolean function
28554 (Ada_Objects_Path.Add): For a library project, add to the object path
28555 the library directory only if there is no object directory or if the
28556 library directory contains ALI files.
28557 (Set_Ada_Paths.Add.Recursive_Add): Ditto
28559 2004-10-26 Vincent Celier <celier@gnat.com>
28561 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
28562 extension of library projects.
28564 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
28565 path defaults to ".:<prefix>/lib/gnat".
28566 (Parse): For an extending all project, allow direct import of a project
28567 that is virtually extended.
28569 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
28570 the specified name is directly imported, return its ID. Otherwise, if
28571 an extension of this project is imported, return the ID of the
28574 2004-10-26 Robert Dewar <dewar@gnat.com>
28576 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
28577 (Sub3): New procedure, used by Scaled_Divide
28578 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
28579 correct more than one instance of failure to propagate carries
28581 (Double_Divide): Handle overflow case of largest negative number
28582 divided by minus one.
28584 * s-arit64.ads (Double_Divide): Document that overflow can occur in
28585 the case of a quotient value out of range.
28588 2004-10-26 Robert Dewar <dewar@gnat.com>
28590 * s-bitops.adb (Bit_Eq): Remove redundant check.
28592 * s-bitops.ads: Minor comment updates
28593 Change some occurrences of Address to System.Address
28595 * s-carsi8.ads: Fix minor cut-and-paste error in comments
28597 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28599 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
28600 accessibility check to prefix that is a protected operation.
28602 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28604 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
28605 empty, post message on stub.
28607 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28608 Javier Miranda <miranda@gnat.com>
28610 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
28611 current instance appears within a unit that is directly in the context
28613 Used to determine whether the body of the instance should be analyzed
28614 immediately after its spec, to make its subprogram bodies available
28615 for front-end inlining.
28616 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
28617 constraint is not allowed on the component type (AARM 12.5.3(3))
28619 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28621 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
28622 'Storage_Pool): enhance, document & limit detection of non-sharable
28625 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
28627 * s-pooglo.ads: Add more documentation now that this pool is properly
28630 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28632 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
28633 or protected type with discriminants, do not constrain the
28634 corresponding record type if the subtype declaration has no
28635 discriminant constraints. This can be the case in source code, or in
28636 the subtype declaration created to rename an actual type within an
28639 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28641 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
28642 different kind of stub (possibly wrong name for file), do not check
28644 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
28645 includes call to some function that returns an unconstrained type, do
28648 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28650 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
28651 appear in the code for the main unit. Dependencies among units in the
28652 context of the main unit are established when those other units are
28653 compiled. Otherwise spurious elaboration constraints can generate
28654 incorrect elaboration circularities.
28656 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28657 Ed Schonberg <schonberg@gnat.com>
28659 * sem_util.adb (Is_Aliased_View): Defend against the case where this
28660 subprogram is called with a parameter that is not an object name. This
28661 situation arises for some cases of illegal code, which is diagnosed
28662 later, and in this case it is wrong to call Is_Aliased, as that might
28663 cause a compiler crash.
28664 (Explain_Limited_Type): Refine previous fix to include
28665 inherited components of derived types, to provide complete information.
28667 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
28668 is the prival for a protected object.
28669 It is necessary to mark this entity as a variable, in addition to
28670 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
28671 modified to avoid checking the Aliased flag on entities that are not
28672 objects. (Checking that flag for non-objects is erroneous and could
28673 lead to a compiler crash).
28675 2004-10-26 Robert Dewar <dewar@gnat.com>
28677 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
28678 X_Frac = 0.5, then we know that the number X must be positive.
28679 (Succ): Remove the same redundant test, and also fix the primary test
28680 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
28682 (Decompose): Add fuller comments to spec
28684 2004-10-26 Pascal Obry <obry@gnat.com>
28686 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
28687 validity (process must have read access). Set to 0 in all other cases.
28688 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
28689 violation on Win32.
28690 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
28691 segmentation violation.
28693 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
28695 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
28696 whose type is a constructed subtype of an aliased object with an
28697 unconstrained nominal subtype, convert the actual to the constructed
28698 subtype before taking its address.

28712 Vincent Celier <celier@gnat.com>
28714 * gnat_ugn.texi: Generalize "finding memory problems" section into a
28715 "memory management issues" section and document some of the useful
28716 memory pools provided as part of the GNAT library.
28717 Remove "virtual" from declaration of A::method2 in
28718 the simple example of Ada/C++ mixed system.
28719 Library Projects may be virtually extended: their virtual extensions
28720 are not Library Projects.
28721 Added section on extending project hierarchies.
28723 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
28725 * adaint.c (__gnat_get_libraries_from_registry): Cast value

28747 other x86 platforms).
28749 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
28751 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
28752 in general and triggers stack alignment adjustment for thread entry
28753 points on targets where this is necessary.
28755 2004-10-04 Bernard Banner <banner@gnat.com>
28758 * Makefile.in: Add section for powerpc linux
28759 Add variant i-vxwork-x86.ads

28766 table registration calls when need be. Ensures no reference to the crt
28767 ctors symbol are issued in the SJLJ case, which avoids possible
28768 undefined symbol errors in the case of modules to be statically linked
28771 2004-10-04 Javier Miranda <miranda@gnat.com>
28773 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
28774 in-line the code corresponding to subprogram Analyze_Actuals. In
28775 addition, analyze the actuals only in case of subprogram call.

28793 2004-10-04 Robert Dewar <dewar@gnat.com>
28795 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
28796 (XMatchD): Avoid warning for Logic_Error call
28798 2004-10-04 Robert Dewar <dewar@gnat.com>
28800 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
28801 consider expressions buried within a procedure actual to be an actual.
28802 This caused some blowups with uses of packed slices within a procedure
28805 2004-10-04 Robert Dewar <dewar@gnat.com>
28807 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
28808 longer need to be initialized to zero.
28809 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
28810 initialized to zero.
28812 * checks.adb (Expr_Known_Valid): Packed arrays are now always
28813 considered valid, even if the representation is modular. That's correct
28814 now that we no longer initialize packed modular arrays to zero.
28816 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
28817 suffixes. These are now documented as the only cases in which the
28818 debugger ignores outer records.
28819 Previously, the spec allowed arbitrary suffixes for this purpose.
28820 Change name of LJM to JM for packed array pad records
28821 Create separate section on packed array handling, and add a whole new
28822 set of comments to this section describing the situation with packed
28823 modular types and justification requirements depending on endianness.
28825 2004-10-04 Robert Dewar <dewar@gnat.com>
28827 * a-except.adb: Add a comment for last change
28829 * einfo.ads: Minor spelling correction in comment

28841 Inline_Always when in Configurable_Run_Time mode.
28843 * sem_prag.adb (Process_Convention): If entity is an inherited
28844 subprogram, apply convention to parent subprogram if in same scope.
28845 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
28846 when in Configurable_Run_Time mode.
28848 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28850 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
28851 class_wide type after component list has been inherited.

28856 Denotes_Previous_Actual, to handle properly the case of a private
28857 actual that is also the component type of a subsequent array actual.
28858 The visibility status of the first actual is not affected when the
28859 second is installed.
28860 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
28861 make fully recursive the treatment of formals of packages declared
28863 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
28864 the above on exit from an instantiation.
28865 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
28866 current instantiation which is now complete.
28867 (Analyze_Package_Instantiation): No instantiated body is needed if the
28868 main unit is generic. Efficient, and avoid anomalies when a instance
28869 appears in a package accessed through rtsfind.
28871 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28873 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
28874 do not generate a declaration for a temporary if the call is part of a
28875 library-level instantiation.
28877 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28879 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
28880 searching for a limited component to flag.
28882 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
28883 expansion of Input, to account for the fact that the implicit call
28884 generated by the attribute reference must freeze the user-defined
28885 stream subprogram. This is only relevant to 'Input, because it can
28886 appear in an object declaration, prior to the body of the subprogram.
28888 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
28889 expansion can proceed and further errors uncovered.
28890 (Minor clean up): Fix cases of using | instead of \ for continuation
28893 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28895 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
28897 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
28898 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.

28902 specified alignment before validating size.
28903 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
28904 stripped-down declaration for the type of the inner field when making
28907 * utils.c (finish_record_type): Do not compute the size in units
28908 incrementally. Instead compute it once for the rep clause case.
28909 Use gcc_assert and gcc_unreachable.
28911 2004-10-04 Vincent Celier <celier@gnat.com>
28913 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
28915 (Is_Valid_Path_Name): Take '/' as a directory separator.
28917 2004-10-04 Vincent Celier <celier@gnat.com>
28919 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
28920 (Extended_Project) only if Extended_Project is defined, to avoid
28922 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
28924 (Parse_Single_Project): Ditto.
28926 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
28927 Add_To_Project_Path for virtual projects.
28929 2004-10-04 Vincent Celier <celier@gnat.com>
28931 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

28935 parameter Options_2.
28937 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
28938 Build_Dynamic_Library with an empty Options_2.
28940 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
28943 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
28944 directory separator, if any.
28945 (Gprmake): Do not allow mains on the command line for library projects.
28946 Do not attempt to link when the project is a library project.
28947 (Library_Opts): New table to store Library_Options.
28948 (Build_Library): If Library_Options is specified, pass these options
28949 when building a shared library.

28973 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
28974 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
28975 used to signal whether the compiler creates the required stacks and
28976 descriptors for the different tasks (when True) or it is done by the
28977 underlying operating system at run time (when False).
28978 It is initially set to False in all targets.
28980 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
28981 if it is supported by the target.
28982 (Make_Task_Create_Call): Pass the stack address if it has been
28983 previously created. Otherwise pass a Null_Address.

28988 statically allocated task stacks.
28990 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
28991 Stack_Address argument.
28992 Check that its value is equal to Null_Address because this target does
28993 not support the static stack allocation.
28995 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
28997 * usage.adb: Change "pragma inline" to "pragma Inline" in information

29002 * exp_dist.adb: Split declaration of asynchronous flag out of
29003 Add_RACW_Read_Attribute.
29004 Minor reformatting for better alignment with PolyORB version.
29005 Store the entity for the asynchronous flag of an RACW, rather than the
29006 expression, in the asynchronous flags table. This will allow this flag
29007 to be used in other subprograms beside Add_RACW_Read_Attribute.
29009 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29011 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

29015 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
29016 sockets constant MSG_NOSIGNAL (Linux-specific).
29017 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
29018 all Send operations.
29019 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
29020 from trigerring SIGPIPE.
29021 Rename components to avoid clash with Ada 2005 possible reserved
29023 (Check_Selector): When the select system call returns with an error
29024 condition, propagate Socket_Error to the caller.
29026 2004-10-01 Jan Hubicka <jh@suse.cz>
29028 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

29038 Minor reformatting.
29040 * freeze.adb (Check_Address_Clause): Remove previous change, not the
29041 right way of doing things after all.
29042 (Freeze_Entity): For object, set Is_Public for imported entities
29043 unless there is an address clause present.
29045 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
29047 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
29048 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
29049 ensures proper handling of types with rep clauses, which might have
29050 their TYPE_SIZE set already.
29052 2004-09-21 Robert Dewar <dewar@gnat.com>
29054 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
29055 packed array types in both little- and big-endian cases. This change
29056 ensures that we no longer count on the unused bits being initialized
29057 for such types (and in particular ensures that equality testing will
29058 only read the relevant bits).
29059 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29060 These changes mean that we no longer need to initialize small packed
29062 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
29063 optimization to an LJM field as to its parent field.
29065 * ada-tree.h, trans.c, utils.c, utils2.c:
29066 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29068 2004-09-20 Jan Hubicka <jh@suse.cz>
29070 * utils.c (gnat_finalize): Remove.
29071 (end_subprog_body): Directly call cgraph_finalize_function;
29072 do not lower the nested functions.
29074 2004-09-20 Robert Dewar <dewar@gnat.com>
29077 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
29078 if an address clause is present, since that means that the Import
29081 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
29083 * 5tsystem.ads: Removed, no longer used.
29085 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>

29107 an existing directory.
29108 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
29109 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
29110 Convert the result to File_Size.
29112 * prj.ads: (Project_Error): New exception
29114 * prj-attr.adb: Except in procedure Initialize, Fail comes from
29115 Prj.Com, not from Osint.
29116 (Attrs, Package_Attributes): Tables moved to private part of spec
29117 (Add_Attribute, Add_Unknown_Package): Moved to new child package
29119 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
29120 Prj.Project_Error after call to Fail.
29121 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
29122 Fail. Check that package name is not already in use.
29124 * prj-attr.ads: Comment updates to indicate that all subprograms may be
29125 used by tools, not only by the project manager, and to indicate that
29126 exception Prj.Prj_Error may be raised in case of problem.
29127 (Add_Unknown_Package, Add_Attribute): Moved to new child package
29129 (Attrs, Package_Attributes): Table instantiations moved from the body to
29130 the private part to be accessible from Prj.Attr.PM body.

29133 from new package Prj.Attr.PM.
29134 (Parse_Attribute_Declaration): Call Add_Attribute from new package
29137 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
29139 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
29140 instead of Elaboration_Checks).
29142 * a-calend.adb: Minor reformatting
29144 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

29202 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
29203 Common_ATCB record. It contains the dynamic level of protected action
29204 nesting for each task. It is needed for checking whether potentially
29205 blocking operations are called from protected operations.
29206 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
29207 Detect_Blocking is active or not in the partition.
29209 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
29210 raise Program_Error if called from a protected operation.
29211 (Task_Entry_Call): When pragma Detect_Blocking is active, raise
29212 Program_Error if called from a protected operation.
29213 (Timed_Task_Entry_Call): When pragma Detect_Blocking is active, raise
29214 Program_Error if called from a protected operation.

29217 raise Program_Error if called from a protected operation.
29219 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
29220 raise Program_Error if called from a protected operation, and increase
29221 the protected action nesting level.
29222 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
29223 Program_Error if called from a protected operation, and increase the
29224 protected action nesting level.

29230 the protected action nesting level.
29231 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
29232 Program_Error if called from a protected operation, and increase the
29233 protected action nesting level.
29234 (Protected_Single_Entry_Call): When pragma Detect_Blocking is active,
29235 raise Program_Error if called from a protected operation.
29236 (Timed_Protected_Single_Entry_Call): When pragma Detect_Blocking is
29237 active, raise Program_Error if called from a protected operation.
29238 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
29239 protected action nesting level.
29241 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
29242 insertion of the statement raising Program_Error. The run time
29243 contains the required machinery for handling that.
29245 * sem_util.ads: Change comment associated to procedure
29246 Check_Potentially_Blocking_Operation.
29247 This procedure does not insert a call for raising the exception because
29248 that is currently done by the run time.
29250 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
29252 * init.c: Add the global variable __gl_detect_blocking that indicates
29253 whether pragma Detect_Blocking is active (1) or not (0). Needed for
29254 making the pragma available at run time.
29255 (__gnat_set_globals): Pass and update the detect_blocking parameter.
29257 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
29258 pragma Detect_Blocking is active.
29260 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
29262 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
29263 DB is found in the ali file. Any unit compiled with pragma
29264 Detect_Blocking active forces its effect in the whole partition.
29266 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
29267 Detect_Blocking is active and delay is called from a protected
29270 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
29271 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
29272 Detect_Blocking is active (0 otherwise).
29273 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
29274 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
29277 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
29279 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
29280 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
29283 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
29284 (Register_Receiving_Stub): Add Subp_Info formal parameter.
29285 Update API in placeholder implemetation of s-parint to reflect changes
29286 in distribution runtime library.
29288 * sem_ch3.adb (Expand_Derived_Record): Rename to
29289 Expand_Record_Extension.
29291 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
29292 primitive operations of potentially distributed object types that have
29293 non-controlling anonymous access formals.
29295 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
29297 New implementation of expansion for remote access-to-subprogram types,
29298 based on the RACW infrastructure.
29299 This version of sem_dist is compatible with PolyORB/DSA as well as
29302 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
29303 Asynchrronous that applies to a remote access-to-subprogram type, mark
29304 the underlying RACW type as asynchronous.
29306 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
29307 __gnat_using_gnu_linker to 1.
29309 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
29310 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
29311 GNAT.Perfect_Hash_Generators, and remove the empty

29316 * exp_ch3.adb (Expand_Derived_Record): Rename to
29317 Expand_Record_Extension.
29318 (Build_Record_Init_Proc.Build_Assignment): The default expression in
29319 a component declaration must remain attached at that point in the
29320 tree so New_Copy_Tree copies it if the enclosing record type is derived.
29321 It is therefore necessary to take a copy of the expression when building
29322 the corresponding assignment statement in the init proc.
29323 As a side effect, in the case of a derived record type, we now see the
29324 original expression, without any rewriting that could have occurred
29325 during expansion of the ancestor type's init proc, and we do not need
29326 to go back to Original_Node.
29328 * exp_ch3.ads (Expand_Derived_Record): Rename to
29329 Expand_Record_Extension.
29331 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

29334 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
29335 New subprograms. Used to create a proxy tagged object for a remote
29336 subprogram. The proxy object is used as the designated object
29337 for RAS values on the same partition (unless All_Calls_Remote applies).
29338 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
29339 System.Partition_Interface.Get_Unique_Remote_Pointer.
29340 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
29341 Renamed from Add_RAS_*_Attribute.
29342 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
29344 New implementation of expansion for remote access-to-subprogram types,
29345 based on the RACW infrastructure.
29347 * exp_dist.ads (Copy_Specification): Update comment to note that this
29348 function can copy the specification from either a subprogram
29349 specification or an access-to-subprogram type definition.
29351 2004-09-09 Ed Schonberg <schonberg@gnat.com>
29353 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
29354 in an instance, between an explicit subprogram an one inherited from a
29355 type derived from an actual.
29357 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
29358 add a polling call if the subprogram is to be inlined by the back-end,
29359 to avoid repeated calls with multiple inlinings.
29361 * checks.adb (Apply_Alignment_Check): If the expression in the address
29362 clause is a call whose name is not a static entity (e.g. a dispatching
29363 call), treat as dynamic.
29365 2004-09-09 Robert Dewar <dewar@gnat.com>
29367 * g-trasym.ads: Minor reformatting
29369 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

29378 2004-09-09 Pascal Obry <obry@gnat.com>
29380 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
29381 enable map file generation. Add the right option to generate the map
29382 file if Map_File is set to True.
29384 * gnatdll.adb (Gen_Map_File): New variable.
29385 (Syntax): Add info about new -m (Map_File) option.

29408 * opt.ads: Add Ada_Version_Runtime constant used to decide which
29409 version of the language is used to compile the run time.
29411 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
29413 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
29414 of variable length temporaries for function return now that the
29415 back-end and gigi support it.

29466 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
29467 packed indexed component where array is an IN OUT formal. This
29468 generated garbage code previously.

29487 expander is not active (but check for unset reference to prefix of
29490 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
29491 pragma Debug as an if statement with a constant condition, for
29492 consistent treatment of entity references contained within the
29493 enclosed procedure call.
29495 2004-09-01 Vincent Celier <celier@gnat.com>
29497 * bindgen.adb: (Set_EA_Last): New procedure
29498 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
29500 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing

29522 2004-09-01 Pascal Obry <obry@gnat.com>
29524 * gprcmd.adb (Extend): Do not output trailing directory separator. This
29525 is not needed and it confuses Windows GNU/make which does not report
29526 directory terminated by a slash as a directory.
29527 (gprcmd): Idem for "pwd" internal command.
29529 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
29530 target names rewrite to fix regressions with recent version of

29582 2004-08-16 Pascal Obry <obry@gnat.com>
29584 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
29585 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
29586 option and not mdll anymore. Update comment.
29588 2004-08-16 Pascal Obry <obry@gnat.com>
29590 * bld.adb (Put_Include_Project): Properly handle directory separators
29593 2004-08-16 Ed Schonberg <schonberg@gnat.com>

29606 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
29608 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
29609 for a global aliased object with a variable size and an unconstrained
29610 nominal subtype, pretend there is no initializer if the one we have is
29611 incomplete, and avoid referencing an inexistant component in there. The
29612 part we have will be rebuilt anyway and the reference may confuse
29613 further operations.
29615 2004-08-13 Thomas Quinot <quinot@act-europe.fr>

29633 2004-08-13 Ed Schonberg <schonberg@gnat.com>
29635 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
29636 unit, this is an attempt to inline a construct that is not available in
29637 the current restricted mode, so abort rather than trying to continue.
29639 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
29640 discriminants that rename those of the parent, recover names of
29641 original discriminants for the constraint on the full view of the
29643 (Complete_Private_Subtype): Do not create a subtype declaration if the
29644 subtype is an itype.
29646 * gnat_rm.texi: Added section on implementation of discriminated
29647 records with default values for discriminants.
29649 2004-08-13 Ed Schonberg <schonberg@gnat.com>

29669 new specification and test explicitly for non-zero return value.
29671 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
29672 returning C.int, to avoid using a derived boolean type.
29674 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
29675 Duplicate_Subexpr_No_Checks in preference to direct use of
29676 Remove_Side_Effects and New_Copy_Tree.

30284 controller type, or an assignment of a record type with controlled
30285 components, copy only user data, and leave the finalization chain

31627 interpretations for rewritten right operand.
31628 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

32264 Merge from tree-ssa-20020619-branch.
32266 * config-lang.in (boot_language, build_by_default): Set

32332 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
32333 overriding, use the operation of the parent unconditionally.
32335 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
32336 operation when either operand is a literal, to avoid further
32339 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
32340 overridden by a previous explicit declaration, mark the previous entity
32343 * sem_disp.adb (Check_Dispatching_Operation): New predicate

32345 primitive control operation for a derived type overrides an inherited

32393 single string literal for pragma arguments.

32405 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was

32410 limitation on length of lines when scanning config pragma files.

33567 * g-curexc.ads: Document that lower bound of returned string values
33570 * gnatlink.adb: Add ??? comment for previous change
33571 (need to document why this is VMS specific)
33573 * s-stoele.ads: Minor reformatting
33575 * tbuild.ads: Minor reformatting throughout (new function specs)
33577 * par-ch10.adb (P_Context_Clause): Handle comma instead of semicolon
33580 * scng.adb: Minor reformatting
33582 2004-04-05 Geert Bosch <bosch@gnat.com>
33584 * eval_fat.adb (Machine): Remove unnecessary suppression of warning.
33585 (Leading_Part): Still perform truncation to machine number if the
33586 specified radix_digits is greater or equal to machine_mantissa.
33588 2004-04-05 Javier Miranda <miranda@gnat.com>
33590 * par-ch3.adb: Complete documentation of previous change
33591 Correct wrong syntax documentation of the OBJECT_DECLARATION rule
33592 (aliased must appear before constant).
33594 * par-ch4.adb: Complete documentation of previous change.
33596 * par-ch6.adb: Complete documentation of previous change.
33598 * sinfo.ads: Fix typo in commment.
33600 2004-04-05 Ed Schonberg <schonberg@gnat.com>
33602 * sem_ch3.adb (Inherit_Components): If derived type is private and has
33603 stored discriminants, use its discriminants to constrain parent type,
33604 as is done for non-private derived record types.
33606 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
33607 Ada 2005 AI-310: an abstract non-dispatching operation is not a
33608 candidate interpretation in an overloaded call.
33610 * tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
33611 expression is Null and target type is not an access type (e.g. a
33612 non-private address type).
33614 2004-04-05 Thomas Quinot <quinot@act-europe.fr>
33616 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
33617 statement whose right-hand side is an inlined call, save a copy of the
33618 original assignment subtree to preserve enough consistency for
33619 Analyze_Assignment to proceed.
33621 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
33622 complete assignment subtree which is now unnecessary, as the expansion
33623 of inlined call has been improved to preserve a consistent assignment
33624 tree. Note_Possible_Modification must be called only
33625 after checks have been applied, or else unnecessary checks will
33628 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
33629 of explicit dereferences that do not Come_From_Source:
33630 - be selective on cases where we must go back to the dereferenced
33631 pointer (an assignment to an implicit dereference must not be
33632 recorded as modifying the pointer);
33633 - do not rely on Original_Node being present (Analyze_Assignment
33634 calls Note_Possible_Modification on a copied tree).
33636 * sem_warn.adb (Check_References): When an unset reference to a pointer
33637 that is never assigned is encountered, prefer '<pointer> may be null'
33638 warning over '<pointer> is never assigned a value'.

33647 * 5gmastop.adb (Pop_Frame): Comment out the pragma Linker_Option for
33648 libexc. We currently don't reference anything in this library and
33649 linking it in triggers linker warnings we don't want to see.
33651 * init.c: Update comments.

33695 Note that prev checkin added RM reference to alignment warning
33697 2004-04-01 Ed Schonberg <schonberg@gnat.com>
33699 * exp_aggr.adb (Get_Component_Val): Treat a string literal as
33700 non-static when building aggregate for bit-packed array.
33702 * exp_ch4.adb (Expand_N_Slice): If a packed slice is an actual of a
33703 function call that is itself the actual in a procedure call, build
33706 * exp_pakd.adb (Expand_Bit_Packed_Element_Set): If right-hand side is
33707 a string literal, create a temporary for it, constant folding only
33708 handles scalars here.
33710 2004-04-01 Vincent Celier <celier@gnat.com>
33712 * ali-util.adb (Post_Scan, Error_Msg, Error_Msg_S, Error_Msg_SC,

33722 Increase the Marking_Label at the end of the Multiple_Main_Loop,
33723 instead of at the beginning.
33725 * osint.adb (Lib_File_Name): Use Multi_Unit_Index_Character, not '~'
33727 (Osint package elaboration): Change Multi_Unit_Index_Character to '$' if
33730 * osint.ads (Multi_Unit_Index_Character): New Character global variable

33823 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
33824 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
33825 type to force the corresponding run-time check
33826 (Resolve_Aggregate): Propagate the null-excluding attribute to the array
33828 (Resolve_Array_Aggregate): Carry out some static checks

33884 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
33886 * osint.adb (Executable_Prefix): Set Exec_Name to the current
33887 executable name when not initialized. Otherwise, use its current value.
33889 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
33890 initialize it to another executable name than the current one. This
33891 allows to configure paths for an executable name (gnatmake) different
33892 from the current one (gnatdist).
33894 2004-03-29 Ed Schonberg <schonberg@gnat.com>
33896 * exp_ch6.adb (Expand_Call): A call to a function declared in the
33897 current unit cannot be inlined if it appears in the body of a withed
33898 unit, to avoid order of elaboration problems in gigi.
33900 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
33901 information for protected (wrapper) operation as well, to simplify gdb
33904 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
33905 protected body, indicate that the entity for the generated spec comes
33906 from source, to ensure that references are properly generated for it.

33914 that renames an equality operator and the operands are overloaded,
33915 resolve them with the declared formal types, before rewriting as an

33941 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
33943 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
33944 attribute reference does not denote a subtype, it can be any
33945 expression that has a classwide type, potentially after an implicit
33946 dereference. In particular, the prefix can be a view conversion for
33947 a classwide type (for which Is_Object_Reference holds), but it can
33948 also be a value conversion for an access-to-classwide type. In the
33949 latter case, there is an implicit dereference, and the original node
33950 for the prefix does not verify Is_Object_Reference.
33952 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
33953 conversion of a discriminant-dependent component of a mutable object
33956 2004-03-25 Ed Schonberg <schonberg@gnat.com>
33958 * freeze.adb (Freeze_Entity): When an inherited subprogram is
33959 inherited, has convention C, and has unconstrained array parameters,
33960 place the corresponding warning on the derived type declaration rather
33961 than the original subprogram.

33964 indication on renaming declaration, if formal has a box and actual

33968 determine whether to generate an implicit or explicit reference to
33969 the renamed entity.

33972 subprogram renaming comes from a defaulted formal subprogram in an
33975 2004-03-25 Gary Dismukes <dismukes@gnat.com>
33977 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
33978 value expressions to ensure that calls within a component definition
33979 will be checked (since those are evaluated during the record type's
33982 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>

34030 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
34031 declaration for a child subprogram body that acts as a spec, indicate
34032 that the entity in the declaration needs debugging information.
34034 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
34035 full view if the subtype is created for a constrained record component;
34036 gigi has enough information to construct the record, and there is no
34037 place in the tree for the declaration.
34039 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
34040 serial number for the dummy body that is built for analysis, to avoid
34041 inconsistencies in the generation of internal names when compiling

34077 * ada-tree.h: Update copyright notice.
34078 Minor reformatting.
34080 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
34082 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
34083 as regular exception objects and not as mere integers representing the
34084 condition code. The latter approach required some dynamics to mask off
34085 severity bits, which did not fit well into the GCC table based model.
34086 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
34087 exception data objects. We don't it and it would conflict with the other
34088 external symbol we have to generate for such exceptions.
34090 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
34091 the special code for VMS exceptions, since these are now represented

34134 * init.c [VxWorks]: Do not fix the stack size for the environment task.
34135 When needed (stack checking) the stack size is retrieved
34136 from the VxWorks kernel.
34138 * Makefile.in: Flag -nostdinc is required when building the run time
34139 for avoiding looking for files in the base compiler.

34172 dirs, when a directory already present is added, the duplicate is
34173 removed and the directory is always put as the last in the table.
34174 Write the path files at the end of these accumulations.

34192 * scn.adb (Determine_License): Take into account a degenerated case
34193 when the source contains only comments.
34195 2004-03-18 Ed Schonberg <schonberg@gnat.com>
34197 * sem_warn.adb (Check_References): For a warning on a selected
34198 component that does not come from source, locate an uninitialized
34199 component of the record type to produce a more precise error message.

34226 imaginary parts, use Double precision throughout.
34228 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
34229 we want to be able to compile run-time with -gnata for testing, but
34230 this may also be instantiated in user code that is compiled with -gnata.

34258 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
34259 System.Standard_Library.Exception_Code, to allow references from the

34263 New accessors to allow easy access to GNAT exception data
34265 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
34266 redundant Handled_By_Others component, helper for the personality
34267 routine which will now be able to call the appropriate exception data
34270 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
34271 component of Standard_Exception_Type to be the closest possible to
34272 Exception_Code in System.Standard_Library, that we cannot get at this
34273 point. Expand a ??? comment to notify that this type node should
34274 probably be rewritten later on.
34276 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
34277 registration call to include a pointer to the exception object in the
34280 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

34294 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
34296 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
34298 * make.adb (Gnatmake): Do not check the executable suffix; it is being
34299 taken care of in Scan_Make_Arg.
34300 (Scan_Make_Arg): Add the executable suffix only if the argument
34301 following -o, in canonical case, does not end with the executable
34302 suffix. When in verbose mode and executable file name does not end
34303 with executable suffix, output the executable name, in canonical case.

34322 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
34323 tagged type is inherited, and the parent operation is not frozen yet,

34325 corresponding dispatch entry is properly initialized.
34326 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
34327 when looking for user-defined equality operation.

34330 boolean when locating primitive equality of tagged component.
34332 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

34383 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
34384 Insert_Dereference_Action when rewriting an implicit dereference into
34385 an explicit one, this will be taken care of during expansion of the
34386 explicit dereference.
34387 (Expand_N_Slice): Same. Always do the rewriting, even for the case
34388 of non-packed slices, since the dereference action generated by
34389 expansion of the explicit dereference is needed in any case.
34390 (Expand_N_Selected_Component): When rewriting an implicit dereference,
34391 analyze and resolve the rewritten explicit dereference so it is seen
34393 (Insert_Dereference_Action): This procedure is now called only for the
34394 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
34395 dereferences that do not come from source (including explicit
34396 dereferences resulting from rewriting implicit ones), but do not
34397 recursively insert a check for the dereference nodes contained within
34399 (Insert_Dereference_Action): Clarify and correct comment.

35276 checks for bitfield creation are triggered.
35277 (finish_record_type): During last pass over the fields, clear
35278 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
35279 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P

35718 Minor reformatting and code clean ups.
35719 Minor changes to prevent -gnatwa warnings
35721 * ali.adb: Minor reformatting and cleanup of code
35722 Acquire new SS indication of secondary stack use from ali files
35724 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
35725 (since now we expect this to be done for imported functions)
35727 * bindgen.adb: Generate call to modify default secondary stack size if
35730 * bindusg.adb: Add line for new -D switch
35732 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
35733 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
35734 Add circuitry for both records and arrays to avoid gigi
35735 processing if the type involved has non-bit-aligned components
35737 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
35738 N_String_Literal node always references an E_String_Literal_Subtype
35739 entity. This may not be true in the future.
35740 (Possible_Bit_Aligned_Component): Move processing of
35741 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
35743 * exp_ch6.adb (Expand_Thread_Body): Pick up
35744 Default_Secondary_Stack_Size as variable so that we get value modified
35745 by possible -Dnnn binder parameter.
35747 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
35748 (Type_May_Have_Bit_Aligned_Components): New function.
35750 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.
35751 (Type_May_Have_Bit_Aligned_Components): New function.

35758 importing constant atomic/volatile objects.
35759 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
35760 unless explicit Pure_Function pragma given, to avoid insidious bug of
35761 call to non-pure imported function getting eliminated.
35763 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
35764 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
35765 gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting

35779 New switch Sec_Stack_Used (GNAT, GNATBIND)
35780 Make Default_Secondary_Stack_Size a variable instead of a constant,
35781 so that it can be modified by the new -Dnnn bind switch.
35783 * rtsfind.adb (Load_Fail): Give full error message in configurable
35784 run-time mode if all_errors mode is set. This was not done in the case
35785 of a file not found, which was an oversight.
35786 Note if secondary stack unit is used by compiler.
35788 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
35789 ineffective elaborate all pragmas on non-visible packages (this
35790 happened when a renamed subprogram was called). Now the elaborate all
35791 always goes on the package containing the renaming rather than the one
35792 containing the renamed subprogram.
35794 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
35795 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
35797 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
35798 has an Etype that references an E_String_Literal.
35799 (Eval_String_Literal): Avoid assumption that N_String_Literal node
35800 always references an E_String_Literal_Subtype entity. This may not
35801 be true in the future.
35803 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
35806 * sem_res.adb (Resolve): Specialize msg for function name used in proc
35809 2004-01-05 Ed Falis <falis@gnat.com>
35811 * g-debuti.adb: Replaced direct boolean operator with short-circuit
35814 2004-01-05 Vincent Celier <celier@gnat.com>
35816 * bld.adb: Minor comment updates
35817 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
35820 * make.adb (Gnatmake): Special process for files to compile/check when
35821 -B is specified. Fail when there are only foreign mains in attribute
35822 Main of the project file and -B is not specified. Do not skip bind/link
35823 steps when -B is specified.
35825 * makeusg.adb: Document new switch -B
35827 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
35829 * switch-m.adb: (Scan_Make_Switches): Process -B switch
35831 * vms_data.ads: Add new GNAT PRETTY qualifier

35843 has size that overflows.
35845 2004-01-05 Gary Dismukes <dismukes@gnat.com>
35847 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
35848 -gnatwa warning on static condition.
35850 2004-01-05 Doug Rupp <rupp@gnat.com>
35852 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
35854 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
35856 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
35857 all attributes, including read-only attribute.
35859 2004-01-05 Pascal Obry <obry@gnat.com>

35862 library naming scheme.
35864 * mlib-prj.adb (Build_Library): Generate different names for the static
35865 or dynamic version of the GNAT runtime. This is needed to support the
35866 new shared library naming scheme.
35867 (Process_Binder_File): Add detection of shared library in binder file
35868 based on the new naming scheme.
35870 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
35871 scheme for the shared runtime libraries.
35874 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
35876 (install-gnatlib): Do not create symlinks for shared libraries.
35877 (gnatlib-shared-default): Idem.
35878 (gnatlib-shared-dual-win32): New target. Not used for now as the
35879 auto-import feature does not support arrays/records.
35880 (gnatlib-shared-win32): Do not create copy for the shared libraries.
35881 (gnatlib-shared-vms): Fix shared runtime libraries names.
35883 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
35884 dependent runtime shared library name.
35886 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
35888 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
35891 2004-01-05 Ed Schonberg <schonberg@gnat.com>
35893 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
35894 protected objects when allocator has a subtype indication, not a
35895 qualified expression. Note that qualified expressions may have to be
35896 checked when limited aggregates are implemented.
35898 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
35899 pure, emit warning.
35900 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
35901 subprogram is imported, remove warning.
35903 2004-01-05 Geert Bosch <bosch@gnat.com>
35905 * s-poosiz.adb: Update copyright notice.
35906 (Allocate): Use Task_Lock to protect against concurrent access.
35907 (Deallocate): Likewise.

35945 * cstand.adb (Create_Standard): Change the way how the declaration of
35946 the Duration type is created (making it the same way as it is for all
35947 the other standard types).

35957 the expression type only if it is declared in the current unit.
35959 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
35960 are universal and already analyzed, as can occur in constrained
35961 subcomponents that depend on discriminants, when one constraint is a

35979 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
35980 (Gnatchop): Do not set failure status when reporting the number of
35983 2003-12-15 Doug Rupp <rupp@gnat.com>
35985 * s-ctrl.ads: New file.

36007 2003-12-11 Ed Falis <falis@gnat.com>
36009 * 5zinit.adb: Clean up.
36011 * 5zintman.adb (Notify_Exception): replaced case statement with a call
36012 to __gnat_map_signal, imported from init.c to support

36046 Minor reformatting throughout
36048 2003-12-11 Ed Schonberg <schonberg@gnat.com>
36050 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
36051 bounds of a loop, create a separate block in order to generate proper
36052 cleanup actions to prevent memory leaks.
36054 * sem_res.adb (Resolve_Call): After a call to
36055 Establish_Transient_Scope, the call may be rewritten and relocated, in

36059 Fixes ACATS regressions.
36062 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always

36068 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
36071 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
36074 2003-12-08 Robert Dewar <dewar@gnat.com>
36076 * 7sintman.adb: Minor reformatting
36078 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
36079 standard linker options to get standard libraries linked. We now plan
36080 to provide dummy versions of these libraries to match the appropriate
36081 configurable run-time (e.g. if a library is not needed at all, provide
36082 a dummy empty library).
36084 * targparm.ads: Configurable_Run_Time mode no longer affects linker
36085 options (-L parameters and standard libraries). What we plan to do is
36086 to provide dummy libraries where the libraries are not required.
36088 * gnatbind.adb: Minor comment improvement
36090 2003-12-08 Javier Miranda <miranda@gnat.com>
36092 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
36093 aggregate in the parent. Otherwise constants with limited aggregates
36094 are not supported. Add new formal to pass the component type (Ctype).
36095 It is required to call the corresponding IP subprogram in case of
36096 default initialized components.
36097 (Gen_Assign): In case of default-initialized component, generate a
36098 call to the IP subprogram associated with the component.
36099 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
36100 of aggregate with default initialized components.
36101 (Has_Default_Init_Comps): Improve implementation to recursively check
36102 all the present expressions.
36104 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
36105 to indicate that the initialization call corresponds to a
36106 default-initialized component of an aggregate.
36107 In case of default initialized aggregate with tasks this parameter is
36108 used to generate a null string (this is just a workaround that must be
36109 improved later). In case of discriminants, this parameter is used to
36110 generate a selected component node that gives access to the discriminant
36113 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
36114 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
36115 allocated aggregates with default-initialized components.
36117 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
36118 the box notation is used in positional aggregates.

36136 Set the scanner to return ends of line and comments as tokens, if
36137 Store_Comments is True.
36138 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
36139 comments are associated with these nodes. Store the node IDs in the
36141 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
36143 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
36144 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
36145 current project. Call Tree.Restore afterwards. Set the various nodes
36146 for comment storage (Next_End, End_Of_Line, Previous_Line,
36149 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
36150 defaulted to False.
36152 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
36153 to False. When Truncated is True, truncate the string, never go to the
36155 (Write_End_Of_Line_Comment): New procedure
36156 (Print): Process comments for nodes N_With_Clause,
36157 N_Package_Declaration, N_String_Type_Declaration,
36158 N_Attribute_Declaration, N_Typed_Variable_Declaration,
36159 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
36160 Process nodes N_Comment.
36162 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
36163 without comments and there are some comments, set the flag
36164 Unkept_Comments to True.
36165 (Scan): If there are comments, set the flag Unkept_Comments to True and
36166 clear the comments.
36167 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
36168 (Next_End_Nodes: New table
36169 (Comment_Zones_Of): New function

36193 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
36194 defaulted to False.
36195 (Scan): Store position of start of comment. If comments are tokens, set
36196 Comment_Id and set Token to Tok_Comment when scanning a comment.
36197 (Set_Comment_As_Token): New procedure
36199 * sinput-p.adb: Update Copyright notice
36200 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
36201 that no longer exists.
36203 2003-12-08 Javier Miranda <miranda@gnat.com>

37714 Remove the test against being in No_Run_Time_Mode before generating a
37715 call to Register_Tag. It is redundant with the test against the
37716 availability of the function Register_Tag.

39923 (general) Add @./@: where approriate, and two spaces after the
39924 full stop at the end of a sentence. Use @samp markup when
39925 referring concrete lexical entities (keywords, attribute names
39926 etc.), and @syntax for ARM grammar elements. Use @r for English
39927 text in comments. Use @emph for emphasis. Change "if-statements"

39941 * make.adb (Add_Switch): Make Generic_Position a procedure. The
39942 function approach did not work well because of a side effect (the
39943 function call could reallocate the table which was being indexed
39944 using its result). Fixes ada/4851.

40311 2001-12-17 Laurent Pautet <pautet@gnat.com>
40314 Fix comment of Shutdown_Socket and Close_Socket. These functions
40315 should not fail silently because if they are called twice, this
40316 probably means that there is a race condition in the user program.
40317 Anyway, this behaviour is consistent with the rest of this unit.
40318 When an error occurs, an exception is raised with the error message
40319 as exception message.

41642 2001-10-11 Pascal Obry <obry@gnat.com>
41645 (GNAT_ADA_OBJS): add g-crc32.o, a-tags.o, a-stream.o
41646 (GNATBIND_OBJS): add g-crc32.o, a-tags.o, a-stream.o
41647 (GNATLS_RTL_OBJS): add g-crc32.o
41648 (GNATMAKE_RTL_OBJS): add g-crc32.o
41651 (CRC_Match): new function.
41652 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
41653 instead of the previous simple checksum algorithm.
41654 (Time_Stamp_Mismatch): use CRC_Match for comparison.
41655 (Set_Source_Table): idem.
41658 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
41659 instead of simple checksum.
41660 (CRC_Match): new function.
41661 (CRC_Error): new constant.
41663 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
41664 a CRC now and not a simple checksum. A CRC uses lower-case hex
41665 letters, fixes ambiguity in parsing.
41667 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
41668 is what this variable will store.
41670 * bcheck.adb: Change reference to chechsum in comments by CRC.
41671 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
41672 rename All_Checksum_Match to All_CRC_Match. Change due to API
41673 renaming since now GNAT does not use a simple checksum but a
41674 CRC using GNAT.CRC32.
41676 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
41677 now and not anymore a simple checksum.
41679 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
41682 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.

41690 (Checksum): rename to CRC.
41691 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
41693 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
41694 GNAT.CRC32). Update copyright notice.
41696 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
41697 GNAT.CRC32). Update copyright notice.
41700 (Accumulate_Checksum): removed.
41701 (Update): new procedure. Add a wide-character into the CRC.

41713 * sinput.ads (Source_Checksum): renamed to Source_CRC.
41714 Update comments for the CRC.
41716 * types.adb (Hex): Use lowercase for the letter part.
41718 * types.ads (Get_Hex_String): Returns the hexadecimal representation
41719 for a word. This is currently used only for CRC. In previous version,
41720 the checksum was using a representation with all letter being
41721 upper-case. With the new implementation (using CRC) we do not remove
41722 the 32th bit of the CRC, so we can have an upper-case starting letter
41723 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
41724 It is ambigous since the CRC was optional and could be followed by
41725 options like EB, EE. So now this routines uses lower-case letter for
41726 the hexadecimal representation. Strange enough only lower case letters
41727 where checked in Scan_ALI (even if this was not a possible case).
41729 * gnatvsn.ads (Library_Version): changed to 3.15a.
41731 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
41734 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
41737 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
41738 Add 2001 to copyright notice
41739 (Accumulate_Checksum): Modify to use System.CRC32.
41741 * ali-util.ads: Redo changes of previous revision to continue to use
41742 the word Checksum. Add 2001 to copyright notice.
41744 * ali.adb: Undo some of previous changes, not needed.
41745 Keep the change for lower case letters in the checksum.
41747 * ali.ads: Undo previous change not needed.
41749 * bcheck.adb: Undo most of previous change, not needed.
41750 But do use Checksums_Match for checksum comparison.
