3656 WITH clause on a private sibling.
3657 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
3658 child unit is a renaming, create an implicit with_clause on that

3726 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
3727 type from a limited_with_clause, and the full view is available, use it

3756 Gary Dismukes <dismukes@adacore.com>
3758 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
3759 requeue statement is dispatching. Do not emit an error when the name is
3760 not an entry and the context is a dispatching select. Add code to
3761 perform subtype conformance between the formals of the current entry
3762 and those of the target interface primitive.
3763 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
3764 Timed_Entry_Call): Analyze the triggering statement as the first step of
3765 the processing. If this is a dispatching select, postpone the analysis
3766 of all select statements until the Expander transforms the select. This
3767 approach avoids generating duplicate identifiers after the Expander has
3768 replicated some of the select statements. In case the Expander is
3769 disabled, perform regular analysis.
3770 (Check_Triggering_Statement): New routine.
3771 (Analyze_Requeue): Exclude any interpretations that are not entries when
3772 checking overloaded names in a requeue. Also test type conformance for
3773 matching interpretations rather than requiring subtype conformance at
3774 that point to conform with the RM's resolution rule for requeues.

3778 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
3779 inherited operation is a defaulted tag-indeterminate call, and there is
3780 a statically tagged actual, use the static tag as a controlling actual
3781 for the defaulted actual.
3783 2007-12-13 Geert Bosch <bosch@adacore.com>
3785 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

4368 multiple inherited interfaces info. This information cannot be stored
4369 in Xref_Entity_Record, which only supports a single instance of Tref_*,

4385 Dismukes). After this patch there is no need to perform any
4386 additional management on these nodes in Expand_Interface_Actuals.
4388 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
4389 that handles use of 'Access and 'Unchecked_Access applied to
4390 actuals covering interface types. Such code is now
4391 centralized in Expand_N_Attribute_Reference.
4393 2007-10-15 Ed Schonberg <schonberg@adacore.com>
4395 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
4396 of tagged types whose ultimate ancestor is a CPP type.

4432 for unsupported configurations; use it on VMS targets instead of the

4435 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
4436 used by VxWorks targets to have access to task-specific data and be
4437 able to extract the stack boundaries for stack checking.

4481 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
4482 association for an access component, add an association with null as
4483 the expression. Remove testing for array subtypes and the setting in
4484 that case of Ctyp to the array component type, which prevented proper
4485 inclusion of an association for null-initialized arrays. Collapse
4486 condition that tests for array subtypes into just a test of

4641 type of file_info_ptr parameter.
4642 If mapped location support is enabled, create the isomorphic mapping
4643 between source files and line maps.
4644 (Sloc_to_locus): If mapped location support is enabled, translate
4645 source location into mapped location.

4672 * a-calend-vms.adb, a-calend.adb:
4673 Add a section on leap seconds control along with two entities used to
4674 enable and disable leap seconds support. The array Leap_Second_Times is
4675 now constant and contains hard time values pre-generated. Remove
4676 all elaboration code used to populate the table of leap seconds.
4679 Add entity Leap_Seconds_Support to the list of global run-time variables
4680 along with a comment on its usage and values.

4737 Eric Botcazou <ebotcazou@adacore.com>
4740 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
4741 indirection added to the HT_Link component of the TSD. This is required
4742 to statically allocate the TSD.
4745 Minor reordering of the declarations in the private part. Required to
4746 add a level of indirection to the contents of the TSD component HT_Link.
4747 This is required to statically allocate the TSD.
4749 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
4750 Is_Statically_Allocated set from constant objects.
4751 Do not make exported constants created by the compiler volatile.
4752 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
4755 * trans.c (Identifier_to_gnu): For constants, unshare initializers
4756 before returning them.
4758 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
4759 public part of the package.
4760 (Make_DT): Move HT_Link component out of the TSD record. For this
4761 purpose Make_DT now declares a separate object that stores the
4762 HT_Link value, and initializes the TSD component with the address
4763 of this new object. The addition of this level of indirection is
4764 required to statically allocate the TSD because the TSD cannot
4765 have variable components.
4766 (Expand_Interface_Conversion): Improve the expanded code.
4767 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
4769 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
4770 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
4771 if we are building static dispatch tables then we must not generate
4772 extra code to register the primitive because the dispatch table will
4773 be built at the end of the library package; otherwise we notify that
4774 we cannot build the static dispatch table.
4776 2007-09-26 Robert Dewar <dewar@adacore.com>
4778 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

4793 for thunks associated with interface types.
4795 * einfo.ads: Improve documentatation of Is_Internal
4796 (Is_Thunk): New attribute applicable to subprograms. True for thunks
4797 associated with interface types.
4798 Extensive comment fixes regarding flags that appear in all entities. The
4799 documentation is now consistent for all such flags (there were a number
4800 of errors in the documentation in this regard).
4802 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
4804 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
4805 of these procedures are passed a function call that already has
4806 build-in-place actuals (testing new flag
4807 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
4808 the case where processing continues.
4809 (Expand_Call): If the call is generated from a thunk body then we
4810 propagate the extra actuals associated with the accessibility
4811 level of the access type actuals.
4813 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
4814 of each extra formal of a protected operation to reference the
4815 corresponding extra formal of the subprogram denoted by the
4816 operation's Protected_Body_Subprogram.
4818 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
4819 N_Function_Call nodes.
4821 2007-09-26 Robert Dewar <dewar@adacore.com>
4823 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
4825 * debug.adb: Add d.s flag.
4827 2007-09-26 Gary Dismukes <dismukes@adacore.com>
4829 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
4830 debug variable so that it won't be initialized when pragma
4831 Initialize_Scalars is in effect.
4833 2007-09-26 Gary Dismukes <dismukes@adacore.com>
4835 * freeze.adb (Freeze_Entity): Remove check for preelaborable
4836 initialization of a full view. This is moved to
4837 Analyze_Package_Specification.
4839 * sem_ch7.adb (Analyze_Package_Specification): Add check for
4840 preelaborable initialization of a full view in entity loop.
4841 (Uninstall_Declarations): If entity is a use-visible compilation unit,
4842 its child units are use-visible only if they are visible child units.
4844 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
4845 whether an expression can be used within a type declaration that
4846 requires preelaborable init.
4847 (Check_Components): Replace inline code that does partial checking for
4848 preelaborable default expressions with call to
4849 Is_Preelaborable_Expression.
4850 (Has_Preelaborable_Initialization): In the case of a generic actual
4851 subtype, (that is, Is_Generic_Actual is True), return the result of
4852 applying Has_Preelaborable_Initialization to the generic actual's base
4855 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
4857 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
4858 call to Jan_1_Day _Of_Week to optimize its performance.
4859 (Is_Leap): Move the routine to the scope of Week_In_Year.
4860 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
4861 weekday on which January 1 falls of Year - 1 and Year + 1. This function
4862 avoids calling Time_Of and Split, thus making it more efficent.
4863 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
4865 * g-calend.ads (Week_In_Year): Change comment to reflect new
4868 2007-09-26 Emmanuel Briot <briot@adacore.com>
4870 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
4871 Command_Line): New types
4872 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
4873 support for defining how switches can be grouped on a command line (as
4874 is the case for -gnatw... for GNAT), and how simple switches can be
4875 used as aliases for more complex switches (-gnatwa is same as
4877 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
4878 (Start, Current_*): New subprograms
4879 Added support for parsing an array of strings in addition to the real
4881 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
4882 be moved from the body to the private part of the spec.
4883 (*): All subprograms now have an extra parameter with default value to
4884 specify which parser should be used. For backward compatibility, it
4885 defaults to parsing the command line of the application. They were also
4886 modified to properly handle cases where each of the argument does not
4887 start at index 1 (which is always true for Ada.Command_Line, but not
4888 when processing any Argument_List).
4889 (Free): New subprogram
4890 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
4891 Argument): New subprograms
4892 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
4893 special characters like ':', '=',... are now handled in a single place,
4894 which makes the code more extensible eventually.
4895 (Getopt, Full_Switch): When the switch was returned as part of the
4896 special character '*', make sure it is prepended by the switch character
4897 ('-' in general), so that the application knows whether "foo" or "-foo"
4898 was specified on the command line.
4900 2007-09-26 Florian Villoing <villoing@adacore.com>
4902 * g-dirope.adb (Remove_Dir): In case we are removing directories
4903 recursively, make sure that if an exception is raised during the
4904 processing, the current working directory is reset to its initial
4905 value before propagating the exception.
4907 2007-09-26 Vincent Celier <celier@adacore.com>
4909 * gnatbind.adb: If there are several ALI files specified and there is
4910 a main program to bind, the first ALI is expected to contain the main
4911 subprogram and the names of the binder generated files will be derived
4912 from the first ALI file name.
4913 (Gnatbind): Fix insertion character in invocation of Error_Msg
4915 2007-09-26 Vincent Celier <celier@adacore.com>
4917 * gnatcmd.adb (Check_Files): Do not include sources that have been
4918 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
4920 2007-09-26 Ed Schonberg <schonberg@adacore.com>
4922 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
4923 information about each of its index types, following the type
4924 reference for its component type.
4926 2007-09-26 Vincent Celier <celier@adacore.com>
4928 * make.adb: (Kill): New procedure (__gnat_kill imported)

4935 sources, so that the correct paths will be found.
4937 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
4939 2007-09-26 Vincent Celier <celier@adacore.com>
4941 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
4943 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
4944 Replace components Compiler_Min_Options and Binder_Min_Options with
4945 Compiler_Required_Switches and Binder_Required_Switches in record
4947 Remove components Default_Language and Config in Project_Tree_Data,
4950 * prj-attr.adb: New attributes Required_Switches (<language>) in
4951 packages Compiler and Binder.
4953 * prj-nmsc.adb: Major rewrite of the processing of configuration
4954 attributes for gprbuild. No impact on GNAT tools.
4956 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

4959 being extended, instead of a shallow copy.
4960 (Process_Project_Tree_Phase_1): New procedure

4962 (Process): Implementation now uses the two new procedures
4964 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
4965 from the project config, not the tree config that no longer exists.

4985 * sem_attr.adb (Analyze_Access_Attribute): Fix missing set of
4988 2007-09-26 Ed Schonberg <schonberg@adacore.com>
4990 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
4991 ancestor of the derived type, the operations are inherited from the
4992 primary dispatch table of the parent.
4993 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
4994 when the context is an explicit type conversion.
4996 2007-09-26 Ed Schonberg <schonberg@adacore.com>
4998 * sem_ch4.adb (Analyze_Qualified_Expression): Apply name resolution
4999 rule for qualified expressions properly, to detect improper conversions

5296 potentially be called.
5297 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
5298 body for 'Output when the type is abstract (only the creation of the
5299 body for 'Input is excluded when the type is abstract).

5301 statement, so that False will be returned for TTS_Stream_Input if the
5302 associated tagged type is an abstract extension. Add comments for

5305 variable, insert init proc call only after the shared variable
5306 procedures have been processed, because the IP call needs to undergo
5307 shared passive variable reference expansion, which requires these
5308 procedures to be available (and elaborated).

5320 type, retrieve its value from the aggregate itself, where it must have
5323 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
5324 to remove other spurious ambiguities on arithmetic operations involving
5325 literals and addresses, on systems where Address is a visible integer
5326 type, when the operator is called in functional notation.
5327 (Try_Primitive_Operation): Within an instance, a call in prefixed form
5328 is legal when the types match, even if the operation is currently

5476 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
5477 library-level package renaming, pass the declaration associated with
5478 the renaming's special debug variable to Qualify_Entity_Names to ensure
5479 that its encoded name is properly qualified.
5481 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
5482 occurring in the list of entities to qualify, and do not attempt to
5483 traverse an entity list in that case. Variables associated with
5484 ` library-level package renamings can now occur in the table.

5510 avoid very deep recursion in the front end, which was causing stack
5513 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
5514 string, and the right operand is a string literal (the case of "" &
5515 "..."), optimize by avoiding copying the right operand -- just use the
5516 value of the right operand directly.
5518 * stringt.adb (Store_String_Chars): Optimize by growing the
5519 String_Chars table all at once, rather than appending characters one by
5521 (Write_String_Table_Entry): If the string to be printed is very long,
5522 just print the first few characters, followed by the length. Otherwise,
5523 doing "pn(n)" in the debugger can take an extremely long time.

5633 (Debug_Renaming_Declaration): Replace creation of an enumeration type
5634 and literal with creation of a variable of type
5635 Standard_Debug_Renaming_Type whose name encodes both the renamed object
5636 and the entity of the renaming declaration.
5637 (Qualify_Entity_Name): Add the delayed qualification of the entity name
5638 part of the name of a variable that has a Debug_Renaming_Link.

5648 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
5649 ancestor part given by an aggregate to test for an unchecked conversion,
5650 since this can occur in some cases when the ancestor part is a function
5651 call, and we don't want to fall into the recursive call to this
5652 procedure in that case.
5654 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
5655 stream attributes on limited types to account for user-specified
5656 attributes as well as whether Input (resp. Output) becomes available
5657 due to Read (resp. Write) being available for the type. Change Boolean
5658 variable to the more accurate name
5659 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
5660 double-"not" predicate at beginning of return statement to more
5661 understandable form.
5663 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
5664 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
5665 in a block statement and use that as the first statement of the
5666 expanded return rather than incorrectly using the handled sequence as
5667 the first statement.
5669 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
5670 operation, generate an explicit freeze node for it rather than
5671 generating extra formals, to ensure that gigi has the proper order of
5672 elaboration for anonymous subtypes in the signature of the subprograms.
5673 (Build_In_Place_Formal): Move assertion to beginning of loop.
5674 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
5675 applied to a function call (occurs for some cases of 'Input).
5676 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
5677 applied to a function call (occurs for some cases of 'Input).
5679 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
5680 2005, generate an extended return statement enclosing the result object
5683 * freeze.adb (Freeze_Record_Type): Extend the current management of
5684 components that are access type with an allocator as default value: add
5685 missing support to the use of qualified expressions of the
5686 allocator (which also cause freezing of the designated type!)
5687 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
5688 dispatching operation, since extra formals may be needed by calls to
5689 build-in-place functions (such as stream 'Input).
5691 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
5692 formals for 'Constrained and accessibility level in the case of a
5693 predefined dispatching operation.
5695 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
5696 point, no need to find the parent node.
5698 2007-08-16 Javier Miranda <miranda@adacore.com>
5700 * exp_attr.adb (Attribute_Priority): Add missing support for entries
5703 2007-08-16 Javier Miranda <miranda@adacore.com>
5705 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
5706 is not really required and can introduce regression with the debugger.
5707 The original problem is fixed with the patch written for checks.adb.
5709 2007-08-16 Thomas Quinot <quinot@adacore.com>
5711 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

5719 Including_Non_Switch set to False.
5721 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
5722 parameter Including_Non_Switch, defaulted to True. When
5723 Including_Non_Switch is False, options that are not switches and
5724 appear as relative path are not converted to absolute paths.

5736 currently inspected is a selected component, retrieve the entity of
5738 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
5739 from the immediate ancestor of Main_Unit_Entity.
5740 (Install_Limited_Withed_Unit): Do not install the limited view of
5741 package P if P is reachable through an ancestor chain from package C
5742 and C also has a with clause for P in its body.
5743 (Has_Limited_With_Clause): New routine.
5744 (Has_With_Clause): New routine.
5746 2007-08-16 Ed Schonberg <schonberg@adacore.com>
5748 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
5749 generic for an enclosing instance is a global reference, even though
5750 its scope is the enclosing instance.

5753 Javier Miranda <miranda@adacore.com>
5755 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

5776 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
5777 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
5778 the statement which is being resolved comes from a predefined library
5779 unit, all non-predefined library interpretations are skipped.
5780 (Resolve_Op_Concat): If string concatenation was folded in the parser,
5781 but the "&" is user defined, give an error, because the folding would
5784 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
5785 the parser has folded a long sequence of concatenations of string
5788 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
5789 and "JMP_BUF" variables as artificial.
5790 (N_String_Literal): Do not use alloca for very long string literals. Use
5791 xmalloc/free instead. Otherwise the stack might overflow.

5843 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
5844 needed for access to concurrent record types generated by the expander.
5845 (Generate_Range_Check): When generating a temporary to capture the
5846 value of a conversion that requires a range check, set the type of the
5847 temporary before rewriting the node, so that the type is always
5848 properly placed for back-end use.
5849 (Apply_Float_Conversion_Check): Handle case where the conversion is
5851 (Get_Discriminal): Code reformatting. Climb the scope stack looking

5867 (Expand_N_Type_Conversion): Test for the case of renamings of access
5868 parameters when deciding whether to apply a run-time accessibility
5870 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
5871 aggregate code before allocator, and ahead of declaration for
5872 temporary, to prevent access before elaboration when the allocator is
5873 an actual for an access parameter.
5874 (Expand_N_Type_Conversion): On an access type conversion involving an
5875 access parameter, do not apply an accessibility check when the
5876 operand's original node was an attribute other than 'Access. We now
5877 create access conversions for the expansion of 'Unchecked_Access and
5878 'Unrestricted_Access in certain cases and clearly accessibility should
5879 not be checked for those.
5881 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
5882 includes a type conversion of a packed component that has been expanded,
5883 recover the original expression for the object, and use this expression
5884 in the post-call assignment statement, so that the assignment is made
5885 to the object and not to a back-end temporary.
5886 (Freeze_Subprogram): In case of primitives of tagged types not defined
5887 at the library level force generation of code to register the primitive
5888 in the dispatch table. In addition some code reorganization has been
5889 done to leave the implementation clear.
5890 (Expand_Call): When expanding an inherited implicit conversion,
5891 preserve the type of the inherited function after the intrinsic
5892 operation has been expanded.
5894 * exp_ch2.ads, exp_ch2.adb
5895 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
5896 of an entry formal appearing in an assignment statement does not assign
5898 (Expand_Current_Value): Instead of calling a routine to determine
5899 whether the prefix of an attribute reference should be optimized or
5900 not, prevent the optimization of such prefixes all together.
5902 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
5903 component whose prefix is known to be of an access type is an implicit
5904 dereference and does not assign to the prefix.
5906 2007-08-14 Ed Schonberg <schonberg@adacore.com>
5907 Robert Dewar <dewar@adacore.com>
5909 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
5910 itype is visited, make an entry into table to link associated node and
5912 Add comments and correct harmless error in Build_NCT_Hash_Tables
5913 (Array_Aggr_Subtype): Associate each itype created for an index type to
5914 the corresponding range construct, and not to the aggregate itself. to

5920 treatment of limited views uniform for all visible declarations in a
5921 limited_withed package.
5922 (New_Copy_Tree): If hash table is being used and itype is visited,
5923 make an entry into table to link associated node and new itype.
5924 (Resolve_Record_Aggregate): Do not add an others box association for a
5925 discriminated record component that has only discriminants, when there
5926 is a box association for the component itself.

5975 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
5976 generation of a freezing node to ensure proper management of null
5977 excluding access types in the backend.
5978 (Create_Extra_Formals): Test base type of the formal when checking for
5979 the need to add an extra accessibility-level formal. Pass the entity E
5980 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
5981 originally being done in a couple of cases), to ensure that the
5982 Extra_Formals list gets set on the entity E when the first entity is
5984 (Conforming_Types): Add missing calls to Base_Type to the code that
5985 handles anonymous access types. This is required to handle the
5986 general case because Process_Formals builds internal subtype entities
5987 to handle null-excluding access types.
5988 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
5989 functions that need it, even when not marked Requires_Overriding.
5990 Improve warnings for in out parameters
5991 (Analyze_Function_Return): Warn for disallowed null return
5992 Warn on return from procedure with unset out parameter
5993 Ensure consistent use of # in error messages
5994 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
5995 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
5996 the implicit conversion of the expression done for anonymous access
5997 types. This is required to generate the code of the null excluding
5998 check (if required).
6000 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
6001 A formal parameter is never publicly referenceable outside of its body.
6002 (Check_References): For an unreferenced formal parameter in an accept
6003 statement, use the same warning circuitry as for subprogram formal
6005 (Warn_On_Unreferenced_Entity): New subprogram, taken from
6006 Output_Unreferenced_Messages, containing the part of that routine that
6007 is now reused for entry formals as described above.
6008 (Goto_Spec_Entity): New function
6009 (Check_References): Do not give IN OUT warning for dispatching operation
6010 Improve warnings for in out parameters
6011 (Test_Ref): Check that the entity is not undefinite before calling
6012 Scope_Within, in order to avoid infinite loops.
6013 Warn on return from procedure with unset out parameter
6014 Improved warnings for unused variables

6017 Javier Miranda <miranda@adacore.com>
6018 Gary Dismukes <dismukes@adacore.com>
6020 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
6021 (Expand_N_Attribute_Reference): Further unify the handling of the
6022 three forms of access attributes, using common code now for all three
6023 cases. Add a test for the case of applying an access attribute to
6024 an explicit dereference when the context is an access-to-interface
6025 type. In that case we need to apply the conversion to the prefix
6026 of the explicit dereference rather than the prefix of the attribute.
6027 (Attribute_Version, UET_Address): Set entity as internal to ensure
6028 proper dg output of implicit importation.
6029 (Expand_Access_To_Type): Removed.
6030 (Expand_N_Attribute_Reference): Merge the code from the three cases
6031 of access attributes, since the processing is largely identical for
6032 these cases. The substantive fix here is to process the case of a
6033 type name prefix (current instance case) before handling the case
6034 of interface prefixes.

6038 Javier Miranda <miranda@adacore.com>
6039 Robert Dewar <dewar@adacore.com>
6041 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
6042 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
6043 type that is an anonymous access to controlled object, establish
6044 an associated finalization chain to avoid corrupting the global
6045 finalization list when a dynamically allocated object designated
6046 by such a component is deallocated.
6047 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
6048 functions that need it, even when not marked Requires_Overriding.
6049 (Initialize_Tag): Replace call to has_discriminants by call to
6050 Is_Variable_Size_Record in the circuitry that handles the
6051 initialization of secondary tags.

6053 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
6054 Suppress_Initialization pragma for a derived type.
6055 (Is_Variable_Size_Record): New subprogram.
6056 (Build_Offset_To_Top_Functions): New implementation that simplifies the
6057 initial version of this routine and also fixes problems causing
6058 incomplete initialization of the table of interfaces.
6059 (Build_Init_Procedure): Improve the generation of code to initialize the
6060 the tag components of secondary dispatch tables.
6061 (Init_Secondary_Tags): New implementation that simplifies the previous
6062 version of this routine.

6066 diagnose attemps to freeze a subprogram when some untagged type of its
6067 profile is a private type whose full view has not been analyzed yet.
6068 (Freeze_Array_Type): Generate init proc for packed array if either
6069 Initialize or Normalize_Scalars is set.
6070 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
6071 constructing the new profile, copy the null_exclusion indicator for each
6072 parameter, to ensure full conformance of the new body with the spec.
6074 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
6075 Create wrappers for constructor functions that need it, even when not
6076 marked Requires_Overriding.
6077 (Covers): Handle properly designated types of anonymous access types,
6078 whose non-limited views are themselves incomplete types.
6079 (Add_Entry): Use an entity to store the abstract operation which hides
6081 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
6082 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
6083 initialization aggregate.

6088 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
6089 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
6090 (Write_Overloads): Output the abstract operator if present.
6091 (Add_Entry): Before inserting a new entry into the interpretation table
6092 for a node, determine whether the entry will be disabled by an abstract
6094 (Binary_Op_Interp_May_Be_Hidden): New routine.
6095 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
6097 (Function_Interp_May_Be_Hidden): New routine.
6098 (Has_Compatible_Type): Do not consider interpretations hidden by
6099 abstract operators when trying to determine whether two types are

6106 Javier Miranda <miranda@adacore.com>
6108 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
6109 types declared in the declarative part of a nested package body or in

6116 output of implicit importation and exportation.
6117 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
6118 first formal of the thunk is always associated with the controlling
6119 type. In addition perform the following code cleanup: remove formal
6120 Thunk_Alias which is no longer required, cleanup evaluation of the
6121 the controlling type, and update the documentation.
6122 Replace occurrence of Default_Prim_Op_Count by
6123 Max_Predef_Prims. Addition of compile-time check to verify
6124 that the value of Max_Predef_Prims is correct.
6125 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
6126 (Make_DT): Add parameter to indicate when type has been frozen by an
6127 object declaration, for diagnostic purposes.

6129 construction of statically allocated dispatch tables.
6130 (Make_DT): In case of library-level tagged types export the declaration
6131 of the primary tag. Remove generation of tags (now done by Make_Tags).
6132 Additional modifications to handle non-static generation of dispatch
6133 tables. Take care of building tables for asynchronous interface types
6134 (Make_Tags): New subprogram that generates the entities associated with
6135 the primary and secondary tags of Typ and fills the contents of Access_
6136 Disp_Table. In case of library-level tagged types imports the forward
6137 declaration of the primary tag that will be declared later by Make_DT.
6138 (Expand_Interface_Conversion): In case of access types to interfaces
6139 replace an itype declaration by an explicit type declaration to avoid
6140 problems associated with the scope of such itype in transient blocks.
6142 2007-08-14 Robert Dewar <dewar@adacore.com>
6143 Ed Schonberg <schonberg@adacore.com>
6144 Javier Miranda <miranda@adacore.com>
6146 * exp_util.ads, exp_util.adb:
6147 This patch replaces a number of occurrences of explicit tests for N_Null
6148 with calls to Known_Null. This improves tracking of null values, since
6149 Known_Null also catches null constants, and variables currently known to
6150 be null, so we get better tracking.
6151 (Ensure_Defined): create an itype reference only in the scope of the
6153 (Side_Effect_Free): A selected component of an access type that
6154 denotes a component with a rep clause must be treated as not
6155 side-effect free, because if it is part of a linked structure its
6156 value may be affected by a renaming.
6157 (Expand_Subtype_From_Expr): For limited objects initialized with build
6158 in place function calls, do nothing; otherwise we prematurely introduce
6159 an N_Reference node in the expression initializing the object, which
6160 breaks the circuitry that detects and adds the additional arguments to
6161 the called function. Bug found working in the new patch for statically
6162 allocated dispatch tables.
6163 (Is_Library_Level_Tagged_Type): New subprogram.
6164 (Remove_Side_Effects): If the expression of an elementary type is an
6165 operator treat as a function call.
6166 (Make_Literal_Range): If the index type of the array is not integer, use
6167 attributes properly to compute the constraint on the resulting aggregate
6170 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
6171 class-wide type whose base type is an incomplete private type, leave
6172 class-wide type unfrozen so that freeze nodes can be generated
6173 properly at a later point.
6174 (Freeze_Entity, array case): Handle case of pragma Pack and component
6175 size attributre clause for same array.

6235 source dirs are not known.
6236 (Check_Ada_Name): Allow all identifiers that are not reserved words
6238 Major update of the Project Manager and of the project aware tools,
6239 including gprmake, so that the same sources in the GNAT repository
6240 can be used by gprbuild.

6824 operations in Derive_Subprograms.
6825 (Collect_Previous_Instances): new procedure within of
6826 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
6827 unit being loaded, to ensure that the generation of global symbols is
6828 consistent in different compilation modes.
6829 (Is_Tagged_Ancestor): New function testing the ancestor relation that
6830 takes progenitor types into account.
6831 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
6832 traversing over the primitives of the formal and actual types to locate
6833 any abstract subprograms of the actual type that correspond to a
6834 nonabstract subprogram of the formal type's ancestor type(s), and issue
6835 an error if such is found.
6836 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,

6838 Remove bogus guard around calls to Inherit_Context.

6850 controlling formal is not an in_parameter, reject the actual if it is
6851 an access_to_constant type.
6852 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
6853 type, the candidate operations are found in the scope of declaration of
6854 the type, because the type has no primitive subprograms.
6855 (Analyze_Selected_Component): If prefix is class-wide, and root type is
6856 a private extension, only examine visible components before trying to
6857 analyze as a prefixed call.
6858 Change Entity_List to Type_To_Use, for better readability.
6859 (Has_Fixed_Op): Use base type when checking whether the type of an
6860 operator has a user-defined multiplication/division

6868 formal At_Any_Place indicating, when True, that we want to test for
6869 availability of the stream attribute at any place (as opposed to the
6870 current visibility context only).
6871 (Missing_Read_Write_Attributes): A stream attribute is missing for the
6872 purpose of enforcing E.2.2(8) only if it is not available at any place.
6873 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
6874 when checking the legality of an extension aggregate in a preelaborable
6875 package. Treat the literal null as a valid default expression in a
6876 component declaration for a type with preelaborable initialization.

8091 Arnaud Charlet <charlet@adacore.com>
8093 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
8094 applicable to types that have the With_Type flag set. Returns the
8095 non-limited view of the type, if available, otherwise the type itself.
8096 For class-wide types, there is no direct link in the tree, so we have
8097 to retrieve the class-wide type of the non-limited view of the Etype.
8098 New attributes Static_Initialization and Static_Elaboration_Desired.
8099 Remove the pragma Thread_Body, and the associated flag
8100 Is_Thread_Body in entities, and all related code.

8110 components of records. Set to point to the entity of the corresponding
8112 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
8113 (Original_Access_Type): Remove, not needed.
8114 (Root_Type): Handle properly subtypes of class-wide-types.
8117 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
8118 class-wide types visible through limited-with clauses.
8119 (Try_Primitive_Operation): When examining all primitive operations of a
8120 tagged type, do not consider subprograms labeled as hidden unless they
8121 belong to a private generic type with a tagged parent.
8122 (Try_Object_Operation): Extensive rewriting, to handle properly various
8123 overloading cases, when several ancestors may have class-wide operations
8124 that are possible candidates, and when the overloaded functions return
8125 array types and have defaulted parameters so that the call may be
8126 interpreted as an indexing.
8127 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
8128 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
8129 successive actuals before analyzing the call itself.
8130 (Try_Primitive_Operation): A primitive operation is compatible with the
8131 prefix if the prefix has a synchronized type and the type of the formal
8132 is its corresponding record, as can be the case when the primitive
8133 operation is declared outside of the body of the type.
8134 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
8135 perform homonym traversal, looking for class-wide operation matches
8136 (formerly done in statements of Try_Class_Wide_Operation). Matches on
8137 access parameters are now restricted to anonymous access types.
8138 (Mark_Allocator): An allocator with a discriminant association parent is
8140 (Try_One_Prefix_Interpretation): If the type of the object is
8141 incomplete, as can be happen when it is a limited view obtained through
8142 a limited_with_clause, the selected component is not part of a prefixed
8144 (Complete_Object_Operation): Diagnose properly an object that is not
8145 aliased when the corresponding controlling formal is an access
8147 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
8148 ambiguous calls in prefixed notation, where two primitives differ only
8149 in that the controlling argument of one is an access parameter.
8151 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
8152 whether a function that returns an unconstrained type can be inlined.
8153 (Process_Formals): Diagnose properly the illegal use of an incomplete
8154 type in the profile of an access_to_subprogram declaration.
8155 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
8156 operations are attached to the corresponding record.
8157 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
8158 When processing a primitive of a concurrent type which implements an
8159 interface change the type of all controlling formals to that of the
8160 corresponding record type.
8161 (Check_Synchronized_Overriding): Relax the conditional logic when trying
8162 to determine the tagged type to which a primitive belongs.
8163 (Check_Conventions): Capture condition to ignore a primitive operation
8164 (which is shared between the loop in Check_Conventions and the one in
8165 Check_Convention) in a new local function Skip_Check.
8166 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
8167 confusion with Check_Conventions' own Prim_Op local variable.
8168 (Create_Extra_Formals): Test for a tagged result type rather than a
8169 controlling result when determining whether to add a BIP_Alloc_Form
8170 formal and a BIP_Final_List formal to the function.
8171 (Check_Conformance); For parameters that are anonymous access types,
8172 subtype conformance requires that the not null and the constant
8173 indicators must match
8174 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
8175 to retrieve the appropriate type when processing a concurrent type
8176 declared within a generic. Minor comment reformatting. Change invocation
8177 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
8179 (Analyze_Subprogram_Body): If the return type of a function is an
8180 anonymous access to the limited view of a class-wide type, and the
8181 non-limited view of the type is available, update the type of the
8182 function so that code can be generated.
8183 (Process_Formals): In case of access-subtype itype whose designated
8184 type is also an itype (situation that happens now with access to
8185 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
8186 attribute to avoid backend problems.
8187 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
8188 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
8189 anonymous types' designated types are same before testing
8190 Subtypes_Statically_Match.
8191 (Create_Extra_Formals): Test for a named access parameter that is a
8192 controlling formal as an additional condition for adding an
8193 accessibility level formal. This can occur in the subp type created for
8194 dispatching calls in Expand_Dispatching_Call, and allows calling
8195 Create_Extra_Formals from that procedure rather than special-casing the
8196 extra formals there.
8197 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
8198 when the function has a controlling result.
8199 (Check_Returns): Add much more knowledge of the optimization of local
8200 raise statements to gotos, to retain proper warnings in this case.
8201 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
8202 nodes when looking for last statement.
8204 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
8205 class-wide types visible through limited with clauses.
8206 (Add_One_Interp): If the operands are anonymous access types, the
8207 predefined operator on universal_access is immediately visibles
8208 (Find_Unique_Type): Handle anonymous access to subprogram types just as
8209 other anonymous access types.
8210 (Disambiguate): Take into account CIL convention.
8211 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
8213 2007-06-06 Robert Dewar <dewar@adacore.com>

8227 Bob Duff <duff@adacore.com>
8228 Hristian Kirtchev <kirtchev@adacore.com>
8230 * exp_aggr.ads, exp_aggr.adb:
8231 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
8232 in extension aggregates.
8233 (Flatten): Other conditions being met, an aggregate is static if the
8234 low bound given by component associations is different from the low
8235 bound of the base index type.
8236 (Packed_Array_Aggregate_Handled): If the component type is itself a
8237 packed array or record, the front-end must expand into assignments.
8238 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
8239 Init_Pr, instead of Ancestor_Is_Expression.
8240 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
8241 coextension chain root, either generate a list controller or use the
8242 already existing one.
8243 (Static_Array_Aggregate): New procedure to construct a positional
8244 aggregate that can be handled by the backend, when all bounds and
8245 components are compile-time known constants.
8246 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
8247 types covering interface types into assignments.
8248 (Replace_Type): move to Build_Record_Aggr_Code.
8249 (Expand_Record_Aggr_Code): if the target of the aggregate is an
8250 interface type, convert to the definite type of the aggregate itself,
8251 so that needed components are visible.
8252 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
8253 components and the context is an extended return statement do not
8254 create a transient block for it, to prevent premature finalization
8255 before the return is executed.
8256 (Gen_Assign): Do not generate a call to deep adjust routine if the
8257 component type is itself an array of controlled (sub)-components
8258 initialized with an inner aggregate.
8259 (Component_Check): New name for Static_Check. This name is now more
8260 appropriate, and documentation is added which was missing.
8261 (Component_Check): Add test for bit aligned component value
8262 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
8263 Tagged_Comps, name is more appropriate given added function below.
8264 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

8267 Javier Miranda <miranda@adacore.com>
8268 Robert Dewar <dewar@adacore.com>
8270 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
8271 Terminated: Add unchecked type conversion from System.Address to
8272 System.Tasking.Task_Id when calling the predefined primitive
8274 Disable new Ada 05 accessibility check for JVM.NET targets, which
8275 cannot be implemented in a practical way.
8276 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
8277 the sources always references the tag of the actual object. Therefore,
8278 if 'Tag is applied in the sources to class-wide interface objects we
8279 generate code that displaces "this" to reference the base of the object.
8280 (Expand_N_Attribute_Reference, case Size): Return specified size if
8282 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
8283 has code that displaces the pointer of the object to manage interface
8284 types. However this code must not be executed when the prefix is a
8285 subprogram. This bug caused the wrong expansion of the internally
8286 generated assignment that fills the dispatch table when the primitive
8287 is a function returning a class-wide interface type.
8288 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
8289 Set_Attribute_Name for Name_Unaligned_Valid.
8291 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8292 Gary Dismukes <dismukes@adacore.com>
8294 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
8295 If the initialization is the equivalent aggregate of the initialization
8296 procedure of the type, do not remove it.
8297 (Expand_N_Attribute_Definition_Clause): Exclude access variables
8298 initialized to null from having their expression reset to empty and
8299 note this exception in the comment.

8303 Ed Schonberg <schonberg@adacore.com>
8304 Gary Dismukes <dismukes@adacore.com>
8306 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
8307 Add "with" and "use" clauses for Sem_Attr.
8308 (Expand_Current_Value): Do not replace occurences of attribute
8309 references where the prefix must be a simple name.
8311 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
8312 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
8313 Attribute_Requires_Simple_Name_Prefix.
8314 (Name_Modifies_Prefix): Body of new function.
8315 (Requires_Simple_Name_Prefix): Body of new function.
8316 (Resolve_Attribute, case Access): Improve error message for case of
8317 mismatched conventions.
8318 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
8320 (Analyze_Attribute, case 'Access): If the type of the prefix is a
8321 constrained subtype for a nominal unconstrained type, use its base type
8322 to check for conformance with the context.
8323 (Resolve_Attribute): Remove test of the access type being associated
8324 with a return statement from condition for performing accessibility
8325 checks on access attributes, since this case is now captured by
8326 Is_Local_Anonymous_Access.
8327 (Analyze_Access_Attribute): Set Address_Taken on entity
8328 (Analyze_Attribute, case Address): Set Address_Taken on entity
8329 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
8330 validating an access attribute whose prefix is a current instance.
8331 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
8332 applied to dispatching operations, if freezing is required then we set
8333 the attribute Has_Delayed_Freeze in the prefix's entity.
8334 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
8335 current scope if access of local subprogram taken
8336 (Analyze_Access_Attribute): Check legality of self-reference even if the
8337 expression comes from source, as when a single component association in
8338 an aggregate has a box association.
8339 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
8340 the prefix if it is a protected operation and the attribute is
8341 Unrestricted_Access.
8342 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
8343 reference to the base type of the context, to force a constraint check
8344 when the context is an access subtype with an explicit constraint.
8345 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
8346 node is rewritten as an interface conversion. leave unanalyzed after
8347 resolution, to ensure that type checking against the context will take

8351 Javier Miranda <miranda@adacore.com>
8352 Robert Dewar <dewar@adacore.com>
8354 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
8355 wrapper when the full view of the controlling type of an inherited
8356 function that dispatches on result implements interfaces.
8357 (Expand_N_Object_Declaration): In cases where the type of the
8358 declaration is anonymous access, create finalization list for it.
8359 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
8360 if the object has no explicit initialization, to match description of
8361 functionality of pragam Persistent_BSS.
8362 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
8363 new function to build static aggregates, to replace initialization call
8364 when static initialization is desired.
8365 (Freeze_Type): Generate a list controller for an access type whenever
8366 its designated type has controlled anonymous access discriminants.
8367 (Build_Equivalent_Aggregate): New procedure to compute a static
8368 aggregate to be used as default initialization for composite types,
8369 instead of a generating a call to the initialization procedure for the
8371 (Build_Initialization_Call): When available, replace a call to the
8372 initialization procedure with a copy of the equivalent static aggregate
8374 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
8375 declarations for objects of a class-wide interface type, rather than
8376 just identifiers, to prevent visibility problems.
8377 (Expand_N_Object_Declaration): When expanding the declaration for an
8378 object of a class-wide interface type, preserve the homonym chain of
8379 the original entity before exchanging it with that of the generated
8380 renaming declaration.
8381 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
8382 active, because there is no way to handle the exception.
8383 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
8384 to do a minimum decoration of the Access_Disp_Table list.
8385 (Expand_Record_Controller): Avoid the addition of the controller between
8386 the component containing the tag of a secondary dispatch table and its
8387 adjacent component that stores the offset to the base of the object.
8388 This latter component is only generated when the parent type has
8389 discriminants ---documented in Add_Interface_Tag_Components).
8390 (Apply_Array_Size_Check): Removed, no longer needed.
8391 (Expand_N_Full_Type_Declaration): If the type has anonymous access
8392 components, create a Master_Entity for it only if it contains tasks.
8393 (Build_Init_Procedure): Suppress the tag assignment compiling under
8395 (Freeze_Record_Type): Remove code associated with creation of dispatch
8397 (Init_Secondary_Tags): Update type of actuals when generating calls to
8398 Ada.Tags.Set_Offset_To_Top
8399 (Stream_Operation_OK): Disable use of streams compiling under no
8401 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
8402 if Has_Init_Expression set.
8403 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
8404 Register_Primitive, which provides the same functionality.
8405 (Requires_Init_Proc): Return false in case of interface types.
8406 (Add_Secondary_Tables): Use the new attribute Related_Interface to
8408 (Predefined_Primitive_Freeze): Do not assume that an internal entity
8409 is always associated with a predefined primitive because the internal
8410 entities associated with interface types are not predefined primitives.
8411 Therefore, the call to Is_Internal is replaced by a call to the
8412 function Is_Predefined_Dispatching_Operation.
8413 (Make_Eq_If): When generating the list of comparisons for the
8414 components of a given variant, omit the controller component that is
8415 present if the variant has controlled components.
8417 2007-06-06 Javier Miranda <miranda@adacore.com>
8418 Hristian Kirtchev <kirtchev@adacore.com>
8419 Bob Duff <duff@adacore.com>
8421 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
8422 handle the creation of finalization lists and calls for nested
8423 coextensions when the root of the chains is part of a return statement.
8424 (Inside_A_Return_Statement): New function inside Complete_Coextension_
8426 (Expand_Record_Equality): Skip components that are interface types.
8427 (Displace_Allocator_Pointer): Add missing support for interface subtypes
8428 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
8429 with Rewrite_Coextension. Change the condition for detecting coextension
8431 (Is_Local_Access_Discriminant): Removed.
8432 (Rewrite_Coextension): New routine which rewrites a static coextension
8433 as a temporary and uses its unrestricted access in the construction of
8435 (Complete_Coextension_Finalization): New routine. Generate finalization
8436 attachment calls to all delayed coextensions.
8437 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
8438 the allocator is not a coextension itself and has delayed coextensions.
8439 If the current allocator is controlled, but also a coextension, delay
8440 the generation of the finalization attachment call.
8441 Rename local variable "Node" to "Nod" in order to avoid confusion with
8443 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
8444 limited types that are not inherently limited. Such an allocator is
8445 illegal, but is generated by the expander for a return statement, to
8446 copy the result onto the secondary stack. This is the only case where a
8447 limited object can be copied. Generate code to displace the pointer
8448 to the object if the qualified expression is a class-wide interface
8449 object. Such displacement was missing and hence the copy of the object
8451 (Apply_Accessibility_Check): Handle allocated objects initialized in
8453 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
8454 and Expand_Allocator_Expression. Allocating class-wide interface objects
8455 this routine displaces the pointer to the allocated object to reference
8456 the component referencing the corresponding secondary dispatch table.
8457 Expand_Allocator_Expression): Add missing support to allocate class-wide
8458 interface objects initialized with a qualified expression.
8459 (Get_Allocator_Final_List): Test for an anonymous access type that is a
8460 function result type, and use the finalization list associated with the
8461 function scope in that case (such an anonymous type should not be
8462 treated like an access parameter's type).
8464 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8465 Gary Dismukes <dismukes@adacore.com>
8466 Javier Miranda <miranda@adacore.com>
8468 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
8469 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
8470 required exception handler.
8471 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
8472 properly the case of a function whose return type is a limited
8473 class-wide interface type. Modify the code of the accessibility
8474 check to handle class-wide interface objects. In this case we need to
8475 displace "this" to reference the primary dispatch table to get access
8476 to the TSD of the object (to evaluate its accessibility level).
8477 (Expand_N_Extended_Return_Statement): Test for a tagged result type
8478 rather than a controlling result as one of the conditions for
8479 generating tests of the implicit BIP_Alloc_Form formal. The
8480 initialization assignment is also handled according to whether the
8481 result is tagged instead of controlling.
8482 In the case where the init assignment is inserted in the "then" part of
8483 the allocation conditional, rewrite the target to be a dereference of
8484 the implicit BIP_Object_Access formal.
8485 If the returned value is unconstrained and created on the secondary
8486 stack, mark the enclosing block and function so that the secondary
8487 stack is not reclaimed on return.
8488 Treat returns from functions with controlling results similarly to
8489 returns from functions with unconstrained result subtypes.
8490 If the object returned is unconstrained, and an allocator must be
8491 created for it, analyze the allocator once the block for the extended
8492 return is installed, to ensure that finalizable components
8493 of the expression use the proper finalization list. Guard the call to
8494 Move_Final_List with a check that there is something to finalize.
8495 (Make_Tag_Ctrl_Assignment): Use "old" handling
8496 of controlled type assignment for virtual machines, since new code uses
8497 unsupported features (such as direct access to bytes in memory).
8499 2007-06-06 Gary Dismukes <dismukes@adacore.com>
8500 Ed Schonberg <schonberg@adacore.com>
8502 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
8503 accessibility actual, check for the case of an aliased object that has
8504 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
8505 we fall into processing for the attribute rather than the name of the
8507 (Expand_Inline_Call): If an actual is a literal, and the corresponding
8508 formal has its address taken in the body, create a temporary to capture
8509 value. If the return type is a limited interface, do not treat the
8510 return value as Controlled.
8511 (Is_In_Place_Function): If the return type is a limited interface,
8512 treat as returning in place. The actual returned object may not always
8513 be limited, but the caller has to assume that it is returned in place.
8514 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
8515 context of an allocator, use the correct finalization chain (that is,
8516 the chain belonging to the access type, rather than the chain belonging
8517 to the current scope).
8518 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
8519 result type rather than a controlling result as a precondition for
8520 adding an allocation form actual to a build-in-place call.
8521 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
8522 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
8523 primitive in the dispatch tables. This work is now done by Make_DT when
8525 (Register_Predefined_DT_Entry): Removed.
8526 (Add_Return): If end label is not present, use sloc of last statement
8527 for generated return statement in procedure, for better gdb behavior
8529 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
8530 object address nodes to ensure proper processing by routines like
8532 (Expand_Call): Fix generation of validity check for parameter
8533 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
8534 the allocation form parameter if the result subtype is constrained,
8535 except when the function has a controlling result.
8536 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
8537 rather than Is_Controlled and Has_Controlled_Component, since we want to
8538 include class-wide result types in this treatment. Also test for a
8539 controlling result, since that also requires passing a finalization
8541 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
8542 even when the result subtype is constrained, to handle calls involving
8543 controlling results.
8544 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
8545 is now called even when the result subtype is constrained, to handle
8546 calls involving controlling results.
8547 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
8548 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
8549 now performs the test).
8550 (Make_Build_In_Place_Call_In_Object_Declaration):
8551 Add_Alloc_Form_Actual_* is now called even when the result subtype is
8552 constrained, to handle calls involving controlling results.
8553 (Add_Return): Accomodate rewritten pattern from local raise to goto
8554 transformation, so that we still recognize an transfer statement
8555 and do the right thing here in that case.
8556 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
8557 and end of subprogram code.
8558 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
8559 support for primitives that are functions (without formals) with a
8561 (Inherited_From_Formal): If the actual subtype has not generic parent
8562 type, it is not an actual for a formal derived type, and there is no
8563 operation to inherit from the formal.
8565 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8566 Thomas Quinot <quinot@adacore.com>
8568 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
8569 inserted cleanup code appropriately for GDB use.
8570 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
8571 exception handler for Deep_Adjust or Deep_Finalize.
8572 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
8573 Raise_From_Controlled_Operation is available, use a call to that
8574 subprogram instead of a plain "raise Program_Error" node to raise
8575 Program_Error if an exception is propagated from an Adjust or Finalize
8577 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
8578 appears in the optional statement list of a triggering alternative, the
8579 scope actions can be inserted directly there, and not in the list that
8580 includes the asynchronous select itself.
8582 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8583 Robert Dewar <dewar@adacore.com>
8584 Hristian Kirtchev <kirtchev@adacore.com>
8586 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
8587 generated exception handler appropriately when debugging generated code.
8588 Deal properly with No_Exception_Propagation restriction mode.
8589 (Expand_N_Abort_Statement): Add an unchecked type conversion from
8590 System.Address to System.Tasking.Task_Id when processing the result of
8591 the predefined primitive _disp_get_task_id.
8592 (Expand_N_Asynchronous_Select): Clarify comment.
8593 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
8594 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
8595 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
8596 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
8597 privals and for generated call to Complete_Entry_Body, for better gdb
8599 (Copy_Result_Type): Utility to construct a parameter and result profile
8600 for protected functions whose return type is an anonymous access to
8602 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
8604 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
8605 point when the local-raise-to-goto transformation has taken place.
8607 2007-06-06 Javier Miranda <miranda@adacore.com>
8608 Nicolas Setton <setton@adacore.com>
8610 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
8611 functionality when the backend is generating code.
8612 Otherwise any serious error
8613 reported by the backend calling the frontend routine Error_Msg
8614 changes the Compilation_Mode to Check_Semantics, disables the
8615 functionality of this routine and causes the generation of
8616 spureous additional errors.
8618 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
8619 debugging information now generated by the compiler for fat-pointer
8621 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
8623 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
8625 2007-06-06 Thomas Quinot <quinot@adacore.com>
8627 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
8628 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
8629 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
8630 For a remote call to a function with a classwide return type, apply an
8631 E.4(18) check to the returned value.
8632 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
8633 stream attributes of the designated type of an RACW, as they are not
8634 dispatching primitive operations.
8636 2007-06-06 Geert Bosch <bosch@adacore.com>
8638 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
8640 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
8642 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
8643 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
8645 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
8647 2007-06-06 Javier Miranda <miranda@adacore.com>
8649 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
8650 attribute compiling package Ada.Tags under No_Run_Time_Mode.
8652 2007-06-06 Javier Miranda <miranda@adacore.com>
8654 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
8655 deallocation of class-wide interface objects.
8656 (Expand_Dispatching_Constructor_Call): Take into account that if the
8657 result of the dispatching constructor is an interface type, the
8658 function returns a class-wide interface type; otherwise the returned
8659 object would be actual. The frontend previously accepted returning
8660 interface types because Expand_Interface_Actuals silently performed
8661 the management of the returned type "as if" it were a class-wide
8663 (Expand_Dispatching_Constructor_Call): Replace call to
8664 Make_DT_Access_Action by direct call to Make_Function_Call.
8666 2007-06-06 Robert Dewar <dewar@adacore.com>
8667 Ed Schonberg <schonberg@adacore.com>
8669 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
8670 compute masking constant, since we now set Esize properly to the
8672 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
8673 to match the alignment.
8674 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
8675 packed arrays of 8 bits or less.
8677 * freeze.adb (Freeze_Entity): When freezing the formals of a

10554 of the record types found in the chain of the package.
10556 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
10557 "abstract subprograms must be visible" message, whether or not the type
10558 is an interface; that is, remove the special case for interface types.

10635 attempt to derive from a synchronized tagged type.
10636 (Analyze_Type_Declaration): If there is a incomplete tagged view of the

10638 already have been used in a self-referential anonymous access component.
10639 (Mentions_T): Recognize self-referential anonymous access components
10640 that use (a subtype of) the class-wide type of the enclosing type.
10641 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
10642 Derived_Type for Prev formal on call to
10643 Check_Anonymous_Access_Components rather than Empty.
10644 (Make_Incomplete_Type_Declaration): Add test for case where the type has

10693 (Compile): When compiling a predefined source, add -gnatpg
10694 as the second switch, after -c.
10695 (Compile_Sources): Allow compilation of Annex J renames without -a

10726 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
10727 when -gnatg is not specified.
10728 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
10729 there is no need to generate always a record_definition_node in case
10730 of synchronized interface types.

10757 (Convert_Aggr_In_Allocator): If the allocator is for an access
10758 discriminant and the type is controlled. do not place on a finalization
10759 list at this point. The proper list will be determined from the

10779 parameter of the containing subprogram.
10780 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
10781 under No_Dispatching_Calls restriction. During the semantic analysis
10782 we already notified such violation.
10783 (Tagged_Membership): Constant folding. There is no need to check
10784 the tag at run-time if the type of the right operand is non
10785 class-wide abstract.

10800 initialize most the TSD components by means of an aggregate.
10801 Modify the declaration of the object containing the TSD
10802 because we now expand code that has a higher level of abstraction.
10803 The TSD has a discriminant containing the Inheritance Depth Level,
10804 value that is used in the membership test but also to fix the size
10805 of the table of ancestors.
10806 (Expand_Interface_Conversion): Insert function body at the closest place
10807 to the conversion expression, to prevent access-before-elaboration

10869 CW_Or_Controlled_Type whenever the issue is related to
10870 using or not the secondary stack.

10962 Thus we must convert the low bound and the length to an appropriate
10963 type before doing the sum.
10964 (Build_Subprogram_Receiving_Stubs, PolyORB):
10965 * Retrieve the extra formals parameters at the
10966 end of the parameter stream.

10977 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
10978 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
10979 Use Build_Actual_Object_Declaration to prepare the actuals.
10980 (Add_Parameter_To_NVList): Set the parameter mode to In for
10981 Extra Constrained Parameters.
10982 (Build_General_Calling_Stubs): Set the parameter type to boolean for

10986 function with the first not implicit parent type.
10987 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
10988 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
10989 typecode from the Etype. Therefore we retrieve the correct typecode
10990 with a call to Get_Any_Type.
10991 (Copy_Specification): Do controlling formal type substitution based on
10992 Is_Controlling_Formal flag, instead of caller-provided object type.
10993 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
10994 a RACW primitive operation, we might get a subprogram declaration for an
10995 ancestor of the RACW designated type (not for the designated type
10996 itself), in the case where this operation is inherited. In this case we
10997 have no easy means of determining the original tagged type for which
10998 the primitive was declared, so instead we now rely on
10999 Copy_Specification to use the Is_Controlling_Formal flag to determine
11000 which formals require type substitution.

11449 because they were defaulted in the formal package and no check applies
11451 (Check_Formal_Package_Instance): Extend conformance check to other
11452 discrete types beyond Integer.
11453 (Process_Default): Copy directly the unmatched formal. A generic copy
11454 has already been performed in Analyze_Formal_Package.
11455 (Analyze_Associations): If a formal subprogram has no match, check for
11456 partial parametrization before looking for a default, to prevent
11458 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
11459 not set the instantiation environment before analyzing the actuals.
11460 Fixes regression on 8515-003 with implementation of AI-133.
11461 Set_Instance_Env checks whether the generic unit is a predefined
11462 unit, in which case the instance must be analyzed with the latest Ada
11463 mode. This setting must take place after analysis of the actuals,
11464 because the actuals must be analyzed and frozen in the Ada mode extant
11465 outside of the current instantiation.
11466 (Save_Env, Restore_Env): Preserve and restore the configuration
11467 parameters so that predefined units can be compiled in the proper Ada
11469 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
11470 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
11471 and Is_Abstract_Type.
11472 (Analyze_Formal_Package): For better error recovery, Add exception
11473 handler to catch Instantion_Error, which can be raised in
11474 Analyze_Associations

11477 Bob Duff <duff@adacore.com>
11478 Gary Dismukes <dismukes@adacore.com>
11480 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
11481 prefix type is a discriminated subtype of the type of the formal.
11482 (Analyze_Allocator): Collect all coextensions regardless of the context.
11483 Whether they can be allocated statically is determined in exp_ch4.
11484 (Analyze_Selected_Component): If the prefix is a limited view and the
11485 non-limited view is available, use the non-limited one.
11486 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
11487 therefore illegal), suggest a qualified expression rather than a type
11488 conversion, because a type conversion would be illegal in this context.
11489 (Anayze_Allocator): Trace recursively all nested allocators so that all
11490 coextensions are on the corresponding list for the root. Do no mark
11491 coextensions if the root allocator is within a declaration for a stack-
11492 allocated object, because the access discriminants will be allocated on
11494 (Analyze_Call): Remove restriction on calls to limited functions for the
11495 cases of generic actuals for formal objects, defaults for formal objects
11496 and defaults for record components.
11497 (Analyze_Allocator): Before analysis, chain coextensions on the proper
11498 element list. Their expansion is delayed until the enclosing allocator
11499 is processed and its finalization list constructed.
11500 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
11501 for an operation with the given name among the primitive operations of
11502 the corresponding record type.
11503 (Analyze_Selected_Component): If the prefix is a task type that
11504 implements an interface, and there is no entry with the given name,
11505 check whether there is another primitive operation (e.g. a function)
11507 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
11508 properly the indexing of a function call written in prefix form, where
11509 the function returns an array type, and all parameters of the function
11510 except the first have defaults.
11511 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
11512 the original operands, rather than relocating them, for efficiency and
11513 to work properly when an operand is overloaded.
11514 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
11515 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
11516 (Analyze_Selected_Component): If the prefix is a private extension, only
11517 scan the visible components, not those of the full view.
11518 (Try_Primitive_Operation): If the operation is a procedure, collect all
11519 possible interpretations, as for a function, because in the presence of
11520 classwide parameters several primitive operations of the type can match
11521 the given arguments.

11531 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11532 Thomas Quinot <quinot@adacore.com>
11534 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
11535 out of Analyze_Package_Declaration, because processing must be applied
11536 to package bodies as well, for deferred constants completed by pragmas.
11537 (Analyze_Package_Declaration): When the package declaration being
11538 analyzed does not require an explicit body, call Check_Completion.
11539 (May_Need_Implicit_Body): An implicit body is required when a package
11540 spec contains the declaration of a remote access-to-classwide type.
11541 (Analyze_Package_Body): If the package contains RACWs, append the
11542 pending subprogram bodies generated by exp_dist at the end of the body.
11543 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
11544 Is_Abstract_Subprogram and Is_Abstract_Type.
11545 (Preserve_Full_Attributes): The full entity list is not an attribute
11546 that must be preserved from full to partial view.
11548 * sem_dist.adb (Add_RAS_Dereference_TSS):
11549 Change primitive name to _Call so it cannot clash with any legal
11550 identifier, and be special-cased in Check_Completion.
11551 Mark the full view of the designated type for the RACW associated with
11552 a RAS as Comes_From_Source to get proper view switching when installing
11553 private declarations.
11554 Provite a placeholder nested package body along with the nested spec
11555 to have a place for Append_RACW_Bodies to generate the calling stubs
11556 and stream attributes.
11558 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11559 Robert Dewar <dewar@adacore.com>
11561 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
11562 that is a limited view, check the non-limited view if available.
11563 (Undefined): Refine error message for missing with of Text_IO
11564 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
11565 to distinguish real missing with cases.
11566 Fix format of all missing with messages
11567 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
11568 renaming as body when renamed entity is abstract.

11583 Javier Miranda <miranda@adacore.com>
11585 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
11586 dereference of a local object R created as a reference to another
11587 object O, use the access level of O.
11588 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
11589 rather than local Same_Formal_Type, to check whether protected operation
11590 overrides an inherited one.
11591 (Same_Formal_Type): New predicate, used when matching signatures of
11592 overriding synchronized operations, to handle the case when a formal
11593 has a type that is a generic actual.
11594 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
11595 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
11596 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
11597 syntactic ambiguities involving indexing of function calls that return
11599 (Abstract_Interface_List): New subprogram that returns the list of
11600 abstract interfaces associated with a concurrent type or a
11601 concurrent record type.
11602 (Interface_Present_In_Parent): New subprogram used to check if a
11603 given type or some of its parents implement a given interface.
11604 (Collect_Abstract_Interfaces): Add support for concurrent types
11605 with interface types.
11606 (Has_Abstract_Interfaces): Add support for concurrent types with
11608 (Is_Parent): New subprogram that determines whether E1 is a parent
11609 of E2. For a concurrent type its parent is the first element of its
11610 list of interface types; for other types this function provides the
11611 same result than Is_Ancestor.
11612 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
11613 (Collect_Synchronized_Interfaces): Removed because the subprogram
11614 Collect_Abstract_Interfaces provides this functionality.
11615 (Collect_Abstract_Interfaces): Minor update to give support to
11616 concurrent types and thus avoid undesired code duplication.
11617 (Get_Subprogram_Entity): Handle entry calls.
11618 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
11620 (Enter_Name): Do not give -gnatwh hiding warning for record component

11636 can be an E_Return_Statement.
11637 (Is_Coextension): New flag for allocators.

11656 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
11657 expression with a COMPOUND_EXPR including the call instead of emitting
11658 the call directly here.
11659 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
11660 high bound is constant and the slice is empty. Tidy.
11661 (tree_transform, case N_Op_Not): Handle properly the case where the
11662 operation applies to a private type whose full view is a modular type.
11663 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
11664 Address_Clause, use the associated Expression as the GNAT tree
11665 representing the choice value to ensure the corresponding GCC tree is
11666 of the proper kind.
11667 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
11668 instead of just the operands, as the base GCC stabilize_reference does.
11669 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
11670 requested; otherwise fail.
11671 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

11676 implementation of UI_Div.
11677 (UI_Div): Reimplement as a call to UI_Div_Rem.
11678 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
11679 remainder, avoiding the cost of a multiplication and a subtraction.
11680 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
11681 provides both quotient and remainder in a single computation.
11682 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
11683 functions for uint.
11684 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

11931 (mainly static expression evaluation).
11932 Reword some continuation messages
11933 Add some \\ sequences to continuation messages
11934 (Resolve_Call): Refine infinite recursion case. The test has been

11948 during analysis, and use May_Be_Lvalue to distinguish read/write.
11949 (Valid_Array_Conversion): New procedure, abstracted from
11950 Valid_Conversion, to incorporate accessibility checks for arrays of
11951 anonymous access types.
11952 (Valid_Conversion): For a conversion to a numeric type occurring in an
11953 instance or inlined body, no need to check that the operand type is
11954 numeric, since this has been checked during analysis of the template.

12542 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
12543 assignments where the target subtype is unconstrained and the target
12544 object is a parameter or dereference (other aliased cases are known

12772 (Make_Null_Procedure_Specs): New procedure to generate null procedure
12773 declarations for overriding null primitives inherited from interfaces.
12774 (Is_Null_Interface_Procedure): New function in
12775 Make_Null_Procedure_Specs.
12776 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
12777 immediate ancestor of a tagged type is an abstract interface type we
12778 must generate the specification of the predefined primitives associated
12779 with controlled types (because the dispatch table of the ancestor is
12780 null and hence these entries cannot be inherited). This is required to
12781 elaborate well the dispatch table.

12789 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
12791 (Expand_N_In): Do validity checks on range
12792 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
12793 (Expand_N_Allocator): For "new T", if the object is constrained by
12794 discriminant defaults, allocate the right amount of memory, rather than
12795 the maximum for type T.
12796 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
12797 when the allocator is initialized by a build-in-place call, since the
12798 allocator is already rewritten as a reference to the function result,
12799 and this prevents an unwanted duplication of the function call.
12800 Add with and use of Exp_Ch6.
12801 (Expand_Allocator_Expresssion): Check for an allocator whose expression
12802 is a call to build-in-place function and apply
12803 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
12804 untagged designated types).
12805 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
12806 optimization if source or target is biased.
12807 (Expand_N_Allocator): Add comments for case of an allocator within a
12808 function that returns an anonymous access type designating tasks.
12809 (Expand_N_Allocator): apply discriminant checks for access
12810 discriminants of anonymous access types (AI-402, AI-416)

12815 Ed Schonberg <schonberg@adacore.com>
12817 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
12819 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
12820 (Expand_N_Assignment_Statement): Call
12821 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
12822 build-in-place function call. Currently, this can happen only for
12823 assignments that come from aggregates.
12824 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
12825 in order to alleviate the upward compatibility introduced by AI-318.
12826 (Expand_N_Extended_Return_Statement): Add support for handling the
12827 return object as a build-in-place result.
12828 (Expand_Non_Function_Return): Implement simple return statements nested
12829 within an extended return.
12830 (Enable_New_Return_Processing): Turn on the new processing of return
12832 (Expand_Non_Function_Return): For a return within an extended return,
12833 don't raise Program_Error, because Sem_Ch6 now gives a warning.
12834 (Expand_N_Extended_Return_Statement): Implement AI-318
12835 (Expand_Simple_Function_Return): Ditto.
12836 (Expand_N_If_Statement): Handle new -gnatwt warning
12837 (Expand_N_Case_Statement): Handle new -gnatwt warning
12838 (Expand_N_Assignment): Handle assignment to the Priority attribute of
12839 a protected object.
12840 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
12841 validity checking of assignments to elementary record components.
12842 (Expand_N_Return_Statement): return Class Wide types on the secondary
12843 stack independantly of their controlled status since with HIE runtimes,
12844 class wide types are not potentially controlled anymore.
12846 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
12849 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
12850 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
12851 it expects a block, procedure, or task. The return statement will get
12852 turned into a block, and Expand_Cleanup_Actions will happen then.

12856 Bob Duff <duff@adacore.com>
12857 Gary Dismukes <dismukes@adacore.com>
12859 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
12861 (Expand_Inlined_Call): Tagged types are by-reference types, and
12862 therefore should be replaced by a renaming declaration in the expanded
12863 body, as is done for limited types.
12864 (Expand_Call): If this is a call to a function with dispatching access
12865 result, propagate tag from context.
12866 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
12868 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
12869 build-in-place when the right-hand side of an assignment is a
12870 build-in-place function call.
12871 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
12872 of the explicit dereference of the allocator to the result subtype of
12873 the build-in-place function. This is needed to satisfy type checking
12874 in cases where the caller's return object is created by an allocator for
12875 a class-wide access type and the type named in the allocator is a
12877 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
12878 conversion of the reference to the declared object to the result subtype
12879 of the build-in-place function. This is needed to satisfy type checking
12880 in cases where the declared object has a class-wide type. Also, in the
12881 class-wide case, change the type of the object entity to the specific
12882 result subtype of the function, to avoid passing a class-wide object
12883 without explicit initialization to the back end.
12884 (Register_Interface_DT_Entry): Moved outside the body of
12885 Freeze_Subprogram because this routine is now public; it is called from
12886 Check_Dispatching_Overriding to handle late overriding of abstract
12887 interface primitives.
12888 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
12889 adding an implicit access actual on a call to a build-in-place function.
12890 (Expand_Actuals): Test for an actual parameter that is a call to a
12891 build-in-place function and apply
12892 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
12893 (Is_Build_In_Place_Function): New function to determine whether an
12894 entity is a function whose calls should be handled as build-in-place.
12895 (Is_Build_In_Place_Function_Call): New function to determine whether an
12896 expression is a function call that should handled as build-in-place.
12897 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
12898 calls to build-in-place functions as the initialization of an allocator.
12899 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
12900 handling calls to build-in-place functions in contexts that do not
12901 involve init of a separate object (for example, actuals of subprogram
12903 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
12904 handling calls to build-in-place functions as the initialization of an
12905 object declaration.
12906 (Detect_Infinite_Recursion): Add explicit parameter Process to
12907 instantiation of Traverse_Body to avoid unreferenced warning.
12908 (Check_Overriding_Inherited_Interfaces): Removed.
12909 (Register_Interface_DT_Entry): Code cleanup.
12910 (Register_Predefined_DT_Entry): Code cleanup.
12911 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
12912 inlined statements if within a transient scope.
12913 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
12914 formal parameters with occurrences of actuals in inlined body, establish
12915 visibility on the proper view of the actual's subtype for the body's
12917 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
12918 compatibility mode and we have an imported CPP subprogram because
12919 for now we assume that imported CPP primitives correspond with
12920 objects whose constructor is in the CPP side (and therefore we
12921 don't need to generate code to register them in the dispatch table).
12922 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
12923 aligned selected component.
12924 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
12925 the actual of an in-mode parameter is a type conversion.
12926 (Expand_Actuals): If the call does not come from source and the actual
12927 is potentially misaligned, let gigi handle it rather than rejecting the
12928 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
12929 Class Wide types as returning by reference independantly of their
12930 controlled status since with HIE runtimes class wide types are not
12931 potentially controlled anymore.
12933 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12935 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
12936 references that are private components of the protected object.

12938 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
12939 instantiation to deal with warnings.

12941 System_Priority as its expected type, in case the expression has not
12944 2006-10-31 Robert Dewar <dewar@adacore.com>
12946 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
12947 initialization of Homonym_Len.
12948 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
12949 names from fully qualified name. Fixes problem of duplicate
12950 external names differing only in the presence of such a block name.
12952 2006-10-31 Thomas Quinot <quinot@adacore.com>
12953 Pablo Oliveira <oliveira@adacore.com>
12955 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
12956 subprogram Ids, even if they are not yet assigned.
12957 (Build_Subprogram_Id): It is now this function that will take care of
12958 calling Assign_Subprogram_Ids if necessary.
12959 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
12960 should be done only once they are assigned.
12961 (Build_From_Any_Function, case of tagged types): Add missing call to
12963 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
12964 type for an RACW type.
12965 (Add_RACW_Features): When processing an RACW declaration for which the
12966 designated type is already frozen, enforce E.2.2(14) rules immediately.
12967 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
12968 special reordering of controlling formals.
12970 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
12971 associated stub type for an RACW type.
12973 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12975 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
12976 fixed-point operations in an integer context, i.e. as operands of a
12977 conversion to an integer type, indicate that result must be rounded.
12979 2006-10-31 Robert Dewar <dewar@adacore.com>
12981 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
12982 cases, pass the encoding method, since it is now required by the run
12985 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
12986 assumption that Str'First = 1.
12987 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
12988 it on to the Value_Wide_Wide_Character call.
12989 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
12990 properly handles a string of the form quote-encoded_wide_char-quote.
12992 * s-wchcnv.adb: Minor reformatting
12994 2006-10-31 Javier Miranda <miranda@adacore.com>
12996 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
12997 run-time membership test to ensure that the constructed object
12998 implements the target abstract interface.
13000 2006-10-31 Robert Dewar <dewar@adacore.com>
13002 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
13003 Machine_Attribute pragma internally to implement the user pragma.
13004 Add processing for pragma Interface so that it is now completely
13005 equivalent to pragma Import.
13007 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
13008 so that it can be applied to all entities, including record components
13009 and enumeration literals.
13010 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
13011 priority ranges are correct, verify compatibility against task
13012 dispatching and locking policies, and if everything is correct an entry
13013 is added to the table containing priority specific dispatching entries
13014 for this compilation unit.
13015 (Delay_Config_Pragma_Analyze): Delay processing
13016 Priority_Specific_Dispatching pragmas because when processing the
13017 pragma we need to access run-time data, such as the range of
13018 System.Any_Priority.
13019 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
13020 Allow pragma Unreferenced as a context item
13021 Add pragma Preelaborable_Initialization
13022 (Analyze_Pragma, case Interface): Interface is extended so that it is
13023 now syntactically and semantically equivalent to Import.
13024 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
13025 insertion characters.
13026 Add handling for Pragma_Wide_Character_Encoding
13027 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
13028 never supercedes a real restriction, and that a real restriction
13029 always supercedes a warning.
13030 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

13035 Robert Dewar <dewar@adacore.com>
13037 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
13038 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
13039 Is_Inherently_Limited_Type, because return-by-reference has no meaning
13041 (Find_Node_To_Be_Wrapped): Use new method of determining the result
13042 type of the function containing a return statement, because the
13043 Return_Type field was removed. We now use the Return_Applies_To field.
13045 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
13046 (Build_Task_Image_Decl): If procedure is not called from an
13047 initialization procedure, indicate that function that builds task name
13048 uses the sec. stack. Otherwise the enclosing initialization procedure
13049 will carry the indication.
13050 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
13051 N_Object_Declaration instead.
13052 (Kill_Dead_Code): New interface to implement -gnatwt warning for
13053 conditional dead code killed, and change implementation accordingly.
13054 (Insert_Actions): Add N_Return_Object_Declaration case.
13055 Correct comment to mention N_Extension_Aggregate node.
13056 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
13057 attempts to save information for global variables which cannot be
13059 (Get_Current_Value_Condition): Handle conditions the other way round
13060 (constant on left). Also handle right operand of AND and AND THEN
13061 (Set_Current_Value_Condition): Corresponding changes
13062 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
13063 (Get_Current_Value_Condition): Handle simple boolean operands
13064 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
13065 (Get_Current_Value_Condition): If the variable reference is within an
13066 if-statement, does not appear in the list of then_statments, and does
13067 not come from source, treat it as being at unknown location.
13068 (Get_Current_Value_Condition): Enhance to allow while statements to be
13069 processed as well as if statements.
13070 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
13072 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
13073 of loop. This is safe now that we fixed Kill_Current_Values.
13074 (OK_To_Do_Constant_Replacement): Check whether current scope is
13075 Standard, before examining outer scopes.
13077 2006-10-31 Vincent Celier <celier@adacore.com>
13079 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
13080 When True, apply VMS treatment to children of packages A, G, I and S.
13083 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
13085 2006-10-31 Robert Dewar <dewar@adacore.com>
13086 Ed Schonberg <schonberg@adacore.com>
13088 * freeze.adb: Add handling of Last_Assignment field
13089 (Warn_Overlay): Supply missing continuation marks in error msgs
13090 (Freeze_Entity): Add check for Preelaborable_Initialization
13092 * g-comlin.adb: Add Warnings (Off) to prevent new warning
13094 * g-expect.adb: Add Warnings (Off) to prevent new warning
13096 * lib-xref.adb: Add handling of Last_Assignment field
13097 (Generate_Reference): Centralize handling of pragma Obsolescent here
13098 (Generate_Reference): Accept an implicit reference generated for a
13099 default in an instance.
13100 (Generate_Reference): Accept a reference for a node that is not in the
13101 main unit, if it is the generic body corresponding to an subprogram
13104 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
13106 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
13108 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
13110 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
13111 use clauses, to avoid messages on packages used to qualify, and also
13112 to avoid messages from obsolescent units.
13113 (Warn_On_Useless_Assignments): Don't generate messages for imported
13114 and exported variables.
13115 (Warn_On_Useless_Assignments): New procedure
13116 (Output_Obsolescent_Entity_Warnings): New procedure
13117 (Check_Code_Statement): New procedure
13119 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
13120 Change name Is_Ada_2005 to Is_Ada_2005_Only
13121 (Last_Assignment): New field for useless assignment warning
13123 2006-10-31 Olivier Hainque <hainque@adacore.com>
13125 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
13126 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
13128 2006-10-31 Bob Duff <duff@adacore.com>
13129 Robert Dewar <dewar@adacore.com>
13130 Ed Schonberg <schonberg@adacore.com>
13132 * g-awk.adb (Default_Session, Current_Session): Compile this file in
13133 Ada 95 mode, because it violates the new rules for AI-318.
13135 * g-awk.ads: Use overloaded subprograms in every case where we used to
13136 have a default of Current_Session. This makes the code closer to be
13137 correct for both Ada 95 and 2005.
13139 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
13140 code, relying on the fact that the compiler generates a warning
13141 instead of an error in -gnatg mode.
13143 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
13144 E_Return_Statement entity kind.
13145 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
13147 * par.adb (P_Interface_Type_Definition): Addition of one formal to
13148 report an error if the reserved word abstract has been previously found.
13149 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
13151 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
13152 parenthesized range attribute usage
13153 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
13155 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
13156 in the syntax for extended_return_statement. This is not in the latest
13157 RM, but the ARG is expected to issue an AI allowing this.
13158 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
13159 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
13160 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
13161 P_Return_Statement): Parse the new syntax for extended_return_statement.
13163 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
13164 Output_End_Missing): Add error-recovery code for the new
13165 extended_return_statement syntax; that is, the new E_Return entry on
13168 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
13169 limited to nonlimited, because otherwise we violate the new Ada 2005
13170 rules about returning limited types in function Create_AST_Handler in
13173 * sem.adb (Analyze): Add cases for new node kinds
13174 N_Extended_Return_Statement and N_Return_Object_Declaration.
13176 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
13177 type is in the same category as type of context before applying check,
13178 to prevent anomalies in instantiations.
13179 (Resolve_Aggregate): Remove test for limited components in aggregates.
13180 It's unnecessary in Ada 95, because if it has limited components, then
13181 it must be limited. It's wrong in Ada 2005, because limited aggregates
13183 (Resolve_Record_Aggregate): Move check for limited types later, because
13184 OK_For_Limited_Init requires its argument to have been resolved.
13185 (Get_Value): When copying the component default expression for a
13186 defaulted association in an aggregate, use the sloc of the aggregate
13187 and not that of the original expression, to prevent spurious
13188 elaboration errors, when the expression includes function calls.
13189 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
13190 were missing. We also didn't handle qualified expressions. Now also
13191 allow function calls. Use new common routine OK_For_Limited_Init.
13192 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
13193 with space can upper case letter).
13195 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
13196 Has_Static_Discriminants flag
13197 (Record_Type_Declaration): Diagnose an attempt to declare an interface
13198 type with discriminants.
13199 (Process_Range_Expr_In_Decl): Do validity checks on range
13200 (Build_Discriminant_Constraints): Use updated form of
13201 Denotes_Discriminant.
13202 (Process_Subtype): If the subtype is a private subtype whose full view
13203 is a concurrent subtype, introduce an itype reference to prevent scope
13205 (Build_Derived_Record_Type, Collect_Interface_Primitives,
13206 Record_Type_Declaration): The functionality of the subprograms
13207 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
13208 is now performed by a single routine.
13209 (Build_Derived_Record_Type): If the type definition includes an explicit
13210 indication of limitedness, then the type must be marked as limited here
13211 to ensure that any access discriminants will not be treated as having
13212 a local anonymous access type.
13213 (Check_Abstract_Overriding): Issue a detailed error message when an
13214 abstract subprogram was not overridden due to incorrect mode of its
13216 (Analyze_Private_Extension_Declaration): Add support for the analysis of
13217 synchronized private extension declarations. Verify that the ancestor is
13218 a limited or synchronized interface or in the generic case, the ancestor
13219 is a tagged limited type or synchronized interface and all progenitors
13220 are either limited or synchronized interfaces.
13221 Derived_Type_Declaration): Check for presence of private extension when
13222 dealing with synchronized formal derived types.
13223 Process_Full_View): Enchance the check done on the usage of "limited" by
13224 testing whether the private view is synchronized.
13225 Verify that a synchronized private view is completed by a protected or
13227 (OK_For_Limited_Init_In_05): New function.
13228 (Analyze_Object_Declaration): Move check for limited types later,
13229 because OK_For_Limited_Init requires its argument to have been resolved.
13230 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
13231 in order to alleviate the upward compatibility introduced by AI-318.
13232 (Constrain_Corresponding_Record): If the constraint is for a component
13233 subtype, mark the itype as frozen, to avoid out-of-scope references to
13234 discriminants in the back-end.
13235 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
13236 this subprogram against wrong sources.
13237 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
13238 discriminant of limited type completed with a protected type, when the
13239 discriminant is used to constrain a private component of the type, and
13240 expansion is disabled.
13241 (Find_Type_Of_Object): Do not treat a return subtype that is an
13242 anonymous subtype as a local_anonymous_type, because its accessibility
13243 level is the return type of the enclosing function.
13244 (Check_Initialization): In -gnatg mode, turn the error "cannot
13245 initialize entities of limited type" into a warning.
13246 (OK_For_Limited_Init): Return true for generated nodes, since it
13247 sometimes violates the legality rules.
13248 (Make_Incomplete_Declaration): If the type for which an incomplete
13249 declaration is created happens to be the currently visible entity,
13250 preserve the homonym chain when removing it from visibility.
13251 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
13252 inherited subprograms.
13253 (Access_Definition): If this is an access to function that is the return
13254 type of an access_to_function definition, context is a type declaration
13255 and the scope of the anonymous type is the current one.
13256 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
13257 incomplete subtype to the set of private dependents of the original
13259 (Constrain_Discriminated_Type): Emit an error message whenever an
13260 incomplete subtype is being constrained.
13261 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
13262 corresponding subtype of the full view of the original incomplete type.
13263 (Check_Incomplete): Properly detect invalid usage of incomplete types

13301 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
13302 call it with -static-libgcc, as there are some platforms, such as
13303 Darwin, where one of these two switches is compulsory to link.

13307 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
13308 instead of ADA_PROJECT_PATH, for the project path.

13312 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
13313 names in the project path, as absolute paths may correspond to
13314 multi-valued VMS logical names.

13347 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
13349 (Layout_Variant_Record): Retrieve the discriminants from the entity
13350 rather than from the type definition, because in the case of a full
13351 type for a private type we need to take the discriminants from the
13353 (Layout_Component_List): When applying the Max operator to variants with
13354 a nonstatic size, check whether either operand is static and scale that
13355 operand from bits to storage units before applying Max.
13356 (Layout_Type): In VMS, if a C-convention access type has no explicit
13357 size clause (and does not inherit one in the case of a derived type),
13358 then the size is reset to 32 from 64.
13360 2006-10-31 Vincent Celier <celier@adacore.com>
13362 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
13363 its file has already been loaded, according to the unit being loaded,
13364 not to the current value of Multiple_Unit_Index.
13366 2006-10-31 Thomas Quinot <quinot@adacore.com>

13402 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13404 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
13405 Process_Body_Clauses): If the context of a body includes a use clause
13406 for P.Q then a with_clause for P in the same body is not redundant,
13407 even if the spec also has a with_clause on P.
13408 Add missing continuation mark to error msg
13409 (Build_Limited_Views): A limited view of a type is tagged if its
13410 declaration includes a record extension.
13411 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
13412 node, even if the subunit has errors. This avoids malfunction by
13413 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
13414 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
13415 generation of obsolescent messages for with statements (cannot do
13416 this too early, or we cannot implement avoiding the messages in the
13417 case of obsolescent units withing obsolescent units).
13418 (Install_Siblings): If the with_clause is on a remote descendant of
13419 an ancestor of the current compilation unit, find whether there is
13420 a sibling child unit that is immediately visible.
13421 (Remove_Private_With_Clauses): New procedure, invoked after completing
13422 the analysis of the private part of a nested package, to remove from
13423 visibility the private with_clauses of the enclosing package

13426 now centralized in Generate_Reference.
13427 (Install_Limited_Context_Clauses): Remove superfluous error
13428 message associated with unlimited view visible through use
13429 and renamings. In addition, at the point in which the error
13430 is reported, we add the backslash to the text of the error
13431 to ensure that it is reported as a single error message.
13432 Use new // insertion for some continuation messages
13433 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
13434 to create implicit with_clause for parent unit mentioned in original
13435 limited_with_clause.

13502 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
13503 dot, instead of replacing only the first '_'.
13505 * prj-part.adb (Parse): Convert project file path to canonical form
13507 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
13508 extended, the project id of the project extending it is recorded in its

13517 Robert Dewar <dewar@adacore.com>
13519 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
13520 only a restriction warning is active for the given restriction. This is
13521 desirable because we do not want to modify code in the case where only
13523 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
13524 causes overriding of real restrictions.
13525 Take advantage of new No_Restrictions constant.
13527 * raise.h: (__gnat_set_globals): Change profile.
13529 2006-10-31 Arnaud Charlet <charlet@adacore.com>

13558 Generalizes previous mechanism to handle attribute references nested
13559 arbitrarily deep within the aggregate.
13560 (Analyze_Access_Attribute): An access attribute whose prefix is a type
13561 can appear in an aggregate if this is a default-initialized aggregate
13562 for a self-referential type.

13576 a class-wide interface to a tagged type.
13577 Add support for the attribute Priority.
13578 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
13579 whether the designated type is discriminated with a constrained partial
13580 view and require static matching in that case.
13581 Add local variable Des_Btyp. The Designated_Type
13582 of an access to incomplete subtype is either its non-limited view if
13583 coming from a limited with or its etype if regular incomplete subtype.

13586 Fix predicate to identify and allow cases of (expander-generated)
13587 references to tag of designated object of a RACW.
13588 (Validate_Static_Object_Name): In Ada 2005, a formal object is

13618 synchronized formal derived type is a synchronized tagged type.
13619 (Instantiate_Formal_Package): When creating the instantiation used to
13620 validate the actual package of a formal declared without a box, check
13621 whether the formal itself depends on a prior actual.
13622 (Instantiate_Formal_Subprogram): Create new entities for the defining
13623 identifiers of the formals in the renaming declaration, for ASIS use.
13624 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
13625 a renaming declaration or a subtype declaration for an actual in an
13626 instance, capture location information of declaration in generic, for

13629 AI-317 (partial parametrization) is fully implemented.
13630 (Validate_Private_Type_Instance): Add check for actual which
13631 must have preelaborable initialization
13632 Use new // insertion for some continuation messages
13633 (Analyze_Formal_Object_Declaration): Change usage of Expression to
13634 Default_Expression. Add type retrieval when the declaration has an
13635 access definition. Update premature usage of incomplete type check.
13636 (Check_Access_Definition): New subsidiary routine. Check whether the
13637 current compilation version is Ada 05 and the supplied node has an
13639 (Instantiate object): Alphabetize local variables. Handle the creation
13640 of new renaming declarations with respect to the kind of definition
13641 used - either an access definition or a subtype mark. Guard against
13642 unnecessary error message in the context of anonymous access types after
13643 they have been resolved. Add check for required null exclusion in a
13644 formal object declaration.
13645 (Switch_View): A private subtype of a non-private type needs to be
13646 switched (the base type can have been switched without its private
13647 dependents because of the last branch of Check_Private_View.
13648 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
13650 (Instantiate_Type): Emit an error message whenever a class-wide type of
13651 a tagged incomplete type is used as a generic actual.
13652 (Find_Actual_Type): Extend routine to handle a component type in a child
13653 unit that is imported from a formal package in a parent.
13654 (Validate_Derived_Type_Instance): Check that analyzed formal and actual

13664 (New_Stream_Subprogram): When processing an attribute definition clause
13665 for a stream-oriented subprogram, record an entity node occurring at

13679 generate the same errors compiling under -gnatc.
13680 (Try_Object_Operation): If no candidate interpretation succeeds, but
13681 there is at least one primitive operation with the right name, report
13682 error in call rather than on a malformed selected component.
13683 (Analyze_Selected_Component): If the prefix is an incomplete type from
13684 a limited view, and the full view is available, use the full view to
13685 determine whether this is a prefixed call to a primitive operation.
13686 (Operator_Check): Verify that a candidate interpretation is a binary
13687 operation before checking the type of its second formal.
13688 (Analyze_Call): Add additional warnings for function call contexts not
13690 (Analyze_Allocator): Move the check for "initialization not allowed for
13691 limited types" after analyzing the expression. This is necessary,
13692 because OK_For_Limited_Init looks at the structure of the expression.
13693 Before analysis, we don't necessarily know what sort of expression it
13694 is. For example, we don't know whether F(X) is a function call or an
13695 indexed component; the former is legal in Ada 2005; the latter is not.
13696 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
13697 were missing. We also didn't handle qualified expressions. Now also
13698 allow function calls. Use new common routine OK_For_Limited_Init.
13699 (Analyze_Type_Conversion): Do not perform some legality checks in an
13700 instance, because the error message will be redundant or spurious.
13701 (Analyze_Overloaded_Selected_Component): Do not do style check when
13702 setting an entity, since we do not know it is the right entity yet.
13703 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
13704 (Analyze_Overloaded_Selected_Component): Same change
13705 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
13706 since regular incomplete subtypes are transformed into corresponding
13707 subtypes of their full views.
13708 (Complete_Object_Operation): Treat name of transformed subprogram call
13709 as coming from source, for browsing purposes.
13710 (Try_Primitive_Operation): If formal is an access parameter, compare
13711 with base type of object to determine whether it is a primitive
13713 (Operator_Check): If no interpretation of the operator matches, check
13714 whether a use clause on any candidate might make the operation legal.
13715 (Try_Class_Wide_Operation): Check whether the first parameter is an
13716 access type whose designated type is class-wide.

13723 warn on infinite loops.
13724 Add \\ to some continuation messages
13725 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
13726 (Process_Bounds): If the bounds are integer literals that result from
13727 constant-folding, and they carry a user-defined type, preserve that type
13728 rather than treating this as an integer range.
13729 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
13730 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
13731 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
13732 left hand side of assignment.
13733 (Analyze_Assignment): Add suport to manage assigments to the attribute
13734 priority of a protected object.
13735 (Check_Possible_Current_Value_Condition): Allow fully qualified names
13736 not just identifiers.
13737 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
13738 or AND THEN for possible tracking.
13739 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
13740 case of while loops so we can track values in the loop body.
13742 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13743 Hristian Kirtchev <kirtchev@adacore.com>
13744 Bob Duff <duff@adacore.com>
13746 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
13747 procedure cannot be a protected operation (it is a basic_declaration,
13748 not a subprogram_declaration).
13749 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
13750 Subp. Add logic for entry processing.
13751 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
13752 Determine whether an entry or subprogram of a protected or task type
13753 override an inherited primitive of an implemented interface.
13754 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
13755 Update the actual used in calls to Check_Overriding_Indicator.
13756 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
13757 generate the proper reference to the parent unit, for cross-reference.
13758 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
13760 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
13761 (Add_Extra_Formal): Revise procedure to allow passing in associated
13762 entity, scope, and name suffix, and handle setting of the new
13763 Extra_Formals field.
13764 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
13765 pass new parameters. Add support for adding the new extra access formal
13766 for functions whose calls are treated as build-in-place.
13767 (Analyze_A_Return_Statement): Correct casing in error message.
13768 Move Pop_Scope to after Analyze_Function_Return, because an extended
13769 return statement really is a full-fledged scope. Otherwise, visibility
13770 doesn't work right. Correct use of "\" for continuation messages.
13771 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
13772 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
13773 the node doesn't get properly marked as analyzed.
13774 (Analyze_Subprogram_Body): If subprogram is a function that returns
13775 an anonymous access type that denotes a task, build a Master Entity
13777 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
13778 proper usage of null exclusion in a result definition.
13779 (Process_Formals): Code cleanup and new error message.
13780 (Process_Formals): Detect incorrect application of null exclusion to
13782 (Conforming_Types): Handle conformance between [sub]types and itypes
13783 generated for entities that have null exclusions applied to them.
13784 (Maybe_Primitive_Operation): Add an additional type retrieval when the
13785 base type is an access subtype. This case arrises with null exclusions.
13786 (New_Overloaded_Entity): Do not remove the overriden entity from the
13787 homonym chain if it corresponds with an abstract interface primitive.
13788 (Process_Formals): Replace membership test agains Incomplete_Kind with a
13789 call to the synthesized predicate Is_Incomplete_Type.
13790 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
13792 (Analyze_Subprogram_Declaration): Check that abstract interface
13793 primitives are abstract or null.
13794 (Analyze_Subprogram_Specification): Remove previous check for abstract
13795 interfaces because it was not complete.
13796 (Has_Interface_Formals): Removed.

13799 Javier Miranda <miranda@adacore.com>
13801 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
13802 of Analyze_Package_Body, to create Itype references for anonymous
13803 access types created in the package declaration, whose designated types
13804 may have only a limited view.
13805 (Analyze_Package_Specification): For the private part of a nested
13806 package, install private_with_clauses of enclosing compilation unit if
13807 we are in its visible part.
13808 (Declare_Inherited_Private_Subprograms): Complete barrier
13809 to ensure that the primitive operation has an alias to some parent
13810 primitive. This is now required because, after the changes done for the
13811 implementation of abstract interfaces, the contents of the list of
13812 primitives has entities whose alias attribute references entities of
13813 such list of primitives.
13814 (Analyze_Package_Specification): Simplify code that handles parent units
13815 of instances and formal packages.
13816 (Uninstall_Declarations): Check the convention consistency among
13817 primitive overriding operations of a tagged record type.

13822 Ed Schonberg <schonberg@adacore.com>
13824 * sem_ch8.adb: Minor error msg rewording

13826 expected and found set right)
13827 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
13828 (Analyze_Generic_Renaming): Same fix
13829 (Use_One_Package): Do not take into account the internal entities of
13830 abstract interfaces during the analysis of entities that are marked
13831 as potentially use-visible.
13832 (Find_Type): Handle the case of an attribute reference for
13833 implementation defined attribute Stub_Type (simply let the analysis of
13834 the attribute reference rewrite it).
13835 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
13836 type that appears in a Use_Type clause.
13837 (Analyze_Object_Renaming): Add support for renaming of the Priority
13839 (Find_Type): In Ada 2005, a task type can be used within its own body,
13840 when it appears in an access definition.
13841 (Analyze_Object_Renaming): Remove warning on null_exclusion.
13842 (Analyze_Object_Renaming): Introduce checks for required null exclusion
13843 in a formal object declaration or in a subtype declaration.
13844 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
13845 (Check_Null_Exclusion): New local routine to
13846 Analyze_Subprogram_Renaming. Check whether the formals and return
13847 profile of a renamed subprogram have required null exclusions when
13848 their counterparts of the renaming already impose them.
13849 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
13850 Determine whether an entity is inside a generic scope.
13851 (In_Open_Scope): First pass of documentation update.
13852 (Find_Expanded_Name): Add support for shadow entities associated with
13853 limited withed packages. This is required to handle nested packages.
13854 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
13855 that makes a renaming of a limited withed package illegal.
13857 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
13858 Ed Schonberg <schonberg@adacore.com>
13860 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
13861 Check_Overriding_Indicator.
13862 (Analyze_Task_Definition): Ditto.
13863 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
13864 (Check_Overriding_Indicator): To find overridden interface operation,
13865 examine only homonyms that have an explicit subprogram declaration, not
13866 inherited operations created by an unrelated type derivation.
13867 (Check_Overriding_Indicator): When checking for the presence of "null"
13868 in a procedure, ensure that the queried node is a procedure
13870 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
13871 type when the formal is an access to variable.
13872 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
13873 (Analyze_Task_Type): Same addition
13874 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
13875 provide navigation capabilities for entries.

13882 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
13883 inherited from an interface ancestor by another interface in the
13884 context of an instance as 'late'.
13885 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
13886 of a call to a function that dispatches on access result.
13887 (Check_Dispatching_Operation): In case of late overriding of a primitive
13888 that covers abstract interface subprograms we register it in all the
13889 secondary dispatch tables associated with abstract interfaces.
13890 (Check_Dispatching_Call): Add check that a dispatching call is not made
13891 to a function with a controlling result of a limited type. This is a
13892 current implementation restriction.
13893 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
13894 (Check_Dispatching_Operation): Do no emit a warning if the controlling
13895 argument is an interface type that is a generic formal.
13896 (Is_Interface_Subprogram): Removed.
13897 (Check_Dispatching_Operation): If the subprogram is not a dispatching
13898 operation, check the formals to handle the case in which it is
13899 associated with an abstract interface type.

13916 Hristian Kirtchev <kirtchev@adacore.com>
13917 Javier Miranda <miranda@adacore.com>
13919 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
13920 subprogram type to provide better diagnostics in case of ambiguity.
13921 (Covers): Handle coverage of formal and actual anonymous access types in
13922 the context of generic instantiation.
13923 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
13924 abstract interface types; this is required to handle concurrent types
13925 with discriminants and abstract interface types.
13926 (Covers): Include type coverage of both regular incomplete subtypes and
13927 incomplete subtypes of incomplete type visibles through a limited with

13939 Add missing continuation marks in error msgs
13940 (Unqualify): New function for removing zero or more levels of
13941 qualification from an expression. There are numerous places where this
13942 ought to be used, but we currently only deal properly with zero or one
13944 (In_Instance); The analysis of the actuals in the instantiation of a
13945 child unit is not within an instantiation, even though the parent
13946 instance is on the scope stack.
13947 (Safe_To_Capture_Value): Exclude the case of variables that are
13949 (Check_Obsolescent): Removed
13950 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
13951 is an aliased view, even when rewritten as a reference to the target
13952 object in an assignment.

13962 has a null exclusion depending on its Nkind.
13963 Change Is_Lvalue to May_Be_Lvalue
13964 (May_Be_Lvalue): Extensive additional code to deal with subprogram
13965 arguments (IN parameters are not Lvalues, IN OUT parameters are).
13966 (Safe_To_Capture_Value): Extend functionality so it can be used for
13967 the current value condition case.
13968 (Has_Compatible_Alignment): New function
13969 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
13970 objects to handle the Ada 2005 case, where aliasedness no longer implies
13971 that the object is constrained. In particular, for dereferenced names,
13972 the designated object must be assumed to be unconstrained.
13973 (Kill_Current_Values): Properly deal with the case where we encounter
13974 a loop in the scope chain.
13975 (Safe_To_Capture_Value): Do not let a loop stop us from capturing

13985 * s-osinte-tru64.adb:
13986 Mark Asm statements Volatile to prevent warnings (seems a
13987 reasonable change anyway)
13990 * s-mastop-irix.adb: Add Volatile to Asm statements
13991 Suppresses warning, and seems appropriate in any case
13993 * s-osinte-vms.adb: Add Volatile to Asm statement

14014 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
14015 (N_Return_Object_Declaration): Remove this node kind. We now use

14018 N_Extended_Return_Statement.
14019 (Procedure_To_Call): Move to a different place to make room in
14020 N_Extended_Return_Statement.
14021 (Return_Type): Removed this field to make room in return statements
14023 (Return_Statement_Entity): New field in return statements, in part to
14024 replace Return_Type, and in part to support the fact that return
14025 statements are now pushed on the scope stack during semantic analysis.
14026 (Return_Object_Declarations): New field to support extended return
14028 (N_Extended_Return_Statement): New node for extended_return_statement
14030 (N_Return_Object_Declaration): New node for part of
14031 extended_return_statement nonterminal. Needed because all the necessary
14032 fields won't fit in N_Extended_Return_Statement.
14033 Generic_associations now carry the Box_Present flag, to indicate a
14034 default for an actual in a partially parametrized formal package.
14036 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
14037 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma

14052 print null exclusion twice in the case of an access definition,
14053 Implement new -gnatL switch
14054 Remove N_Return_Object_Declaration. We now use
14055 N_Object_Declaration instead. Implement the case for
14056 N_Extended_Return_Statement. Alphabetize the cases.
14057 Add cases for new nodes N_Extended_Return_Statement and
14058 N_Return_Object_Declaration. The code is not yet written.
14059 Update the output for N_Formal_Object_Declaration
14060 and N_Object_Renaming_Declaration.

14079 * s-scaval.adb (Initialize): Add new Boolean flag AFloat that is set
14080 True when AAMP extended floating-point is in use (48-bit). Change type
14081 ByteLF to ByteLLF, add new array type ByteLF and condition the size of
14082 the two byte array types on AFloat. Change type of IV_Ilf overlay
14083 variable from Byte8 to ByteLF. Add appropriate initializations of
14084 floating-point overlays for AAMP cases.

14112 2006-10-31 Olivier Hainque <hainque@adacore.com>
14114 * s-stchop.ads: make this unit preelaborate. This is desirable in
14115 general and made mandatory by the use of this unit by s-taprop which
14116 is itself preelaborate.
14118 * s-stchop-vxworks.adb (Set_Stack_Info, Task_Descriptor type): Add
14119 Td_Events component.

14686 the current instance is nested within another instance in a child unit.
14688 2006-02-17 Javier Miranda <miranda@adacore.com>
14689 Ed Schonberg <schonberg@adacore.com>
14691 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
14692 type we cannot inherit the primitive operations; we inherit the
14693 Corresponding_Record_Type (which has the list of primitive operations).
14694 (Check_Anonymous_Access_Types): When creating anonymous access types for
14695 access components, use Rewrite in order to preserve the tree structure,
14697 (Analyze_Object_Declaration): For limited types with access
14698 discriminants with defaults initialized by an aggregate, obtain
14699 subtype from aggregate as for other mutable types.
14700 (Derived_Type_Declaration): If the derived type is a limited interface,
14701 set the corresponding flag (Is_Limited_Record is not sufficient).

14707 expression must be the first variable declared in the body of the
14710 2006-02-17 Javier Miranda <miranda@adacore.com>
14712 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
14713 abstract interface type, the static analysis is not enough to know if
14714 the interface is implemented or not by the source tagged type. Hence
14715 we must pass the work to the expander to generate the required code to
14716 evaluate the conversion at run-time.
14717 (Resolve_Equality_Op): Do not apply previous
14718 transformation if expansion is disasbled, to prevent anomalies when
14719 locating global references in a generic unit.

14753 this to ["5B"] and the new comments say why not.
14756 Add note for -gnatVo that this now includes the cases of type
14757 conversions and qualified expressions.

14899 table to take advantage of the 16 priority levels available on Windows
14900 2000 and XP. On NT4 there are only 7 priority levels, this is properly
14901 supported by this new mapping.

14947 (Read): Change the implementation to support unicode characters. It is
14948 not possible to use strlen() on Windows as this version supports only
14949 standard ASCII characters. So the length of the directory entry is now
14950 returned from the imported __gnat_readdir routine.

14988 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
14989 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
14990 necessary since these are not different types and pointers may
14991 actually designate any subtype in this hierarchy.
14992 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
14993 discriminants but put them into record only if not Unchecked_Union;
14994 pass flag to components_to_record showing Unchecked_Union.

14996 components before variants; don't set TYPE_UNCHECKED_UNION_P.

14998 Remove special case code for Unchecked_Union and instead use main code
14999 with small changes.
15002 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
15003 variable with the expression being built, only its inner field.

15016 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
15017 discriminants of Unchecked_Union.
15018 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses
15019 don't need cluttering preprocessor directives.
15020 (establish_gnat_vms_condition_handler): New function. Establish the GNAT
15021 condition handler as current in the compiled function.
15022 (body_with_handlers_p): New function. Tell whether a given sequence of
15023 statements node is attached to a package or subprogram body and involves
15024 exception handlers possibly nested within inner block statements.
15025 (emit_sequence_entry_statements): New function, to emit special
15026 statements on entry of sequences when necessary. Establish GNAT
15027 condition handler in the proper cases for VMS.

15057 other basic tools. The full version that includes the Ada 2005 stuff

15391 save/restore routines.
15392 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

15394 Since we are changing the tree format anyway, also get rid of the
15395 junk obsolete Immediate_Errors flag.
15396 (Tree_Read): Change the way of reading Tree_Version_String - now we

15477 * sinfo.ads: Document that Mechanism_Code cannot be applied to
15478 renamed subprograms so that the front-end must replace the prefix

15487 (Freeze_Record_Type): Do not generate the tables associated with
15488 timed and conditional dispatching calls through synchronized
15489 interfaces if compiling under No_Dispatching_Calls restriction.
15490 When compiling for Ada 2005, for a nonabstract
15491 type with a null extension, call Make_Controlling_Function_Wrappers
15492 and insert the wrapper function declarations and bodies (the latter
15493 being appended as freeze actions).
15494 (Predefined_Primitive_Bodies): Do not generate the bodies of the
15495 predefined primitives associated with timed and conditional
15496 dispatching calls through synchronized interfaces if we are
15497 compiling under No_Dispatching_Calls.
15498 (Build_Init_Procedure): Use RTE_Available to check if a run-time
15499 service is available before generating a call.
15500 (Make_Controlling_Function_Wrappers): New procedure.
15501 (Expand_N_Full_Type_Declaration): Create a class-wide master for
15502 access-to-limited-interfaces because they can be used to reference
15503 tasks that implement such limited interface.
15504 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
15505 procedure spec and body of the Offset_To_Top function that is generated
15506 when the parent of a type with discriminants has secondary dispatch
15508 (Init_Secondary_Tags): Handle the case in which the parent of the type
15509 containing secondary dispatch tables has discriminants to generate the
15510 correct arguments to call Set_Offset_To_Top.
15511 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
15513 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
15514 Add Wide_[Wide_]Expanded_Name.
15515 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
15516 the same functionality of Get_Prim_Op_Address but applied to predefined
15517 primitive operations because the pointers to the predefined primitives
15518 are now saved in a separate table.
15519 (Parent_Size): Modified to get access to the separate table of primitive
15520 operations or the parent type.
15521 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
15522 functionality of Set_Prim_Op_Address but applied to predefined primitive
15524 (Set_Signature): New subprogram used to store the signature of a DT.
15525 (Displace): If the Offset_To_Top value is not static then call the
15526 function generated by the expander to get such value; otherwise use
15527 the value stored in the table of interfaces.
15528 (Offset_To_Top): The type of the actual has been changed to Address to
15529 give the correct support to tagged types with discriminants. In this
15530 case this value is stored just immediately after the tag field.
15531 (Set_Offset_To_Top): Two new formals have been added to indicate if the
15532 offset_to_top value is static and hence pass this value to the run-time
15533 to store it in the table of interfaces, or else if this value is dynamic
15534 and then pass to the run-time the address of a function that is
15535 generated by the expander to provide this value for each object of the
15538 * rtsfind.ads (Default_Prin_Op_Count): Removed.
15539 (Default_Prim_Op_Count): New entity

15550 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
15551 in a subprogram are wrapped in a cleanup block, indicate that the
15552 subprogram contains an inner block with an exception handler.
15553 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
15554 Adjust call is for a newly-allocated object. In that case we must not
15555 assume that the finalization list chain pointers are correct (since they
15556 come from a bit-for-bit copy of the original object's pointers) so if
15557 the attach level would otherwise be zero (no change), we set it to 4
15558 instead to cause the pointers to be reset to null.
15560 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
15561 reset chain pointers to null.
15563 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15565 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
15566 string, and the context requires a loop for the assignment (e.g.
15567 because the left-hand side is packed), generate a unique name for the
15568 temporary that holds the string, to prevent spurious name clashes.

15572 Robert Dewar <dewar@adacore.com>
15573 Gary Dismukes <dismukes@adacore.com>
15575 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
15576 return unconstrained arrays.
15578 (Expand_Call): An indirect call through an access parameter of a
15579 protected operation is not a protected call.
15580 Add circuit to raise CE in Ada 2005 mode following call
15581 to Raise_Exception.
15582 (Register_DT_Entry): Do nothing if
15583 the run-time does not give support to abstract interfaces.
15584 (Freeze_Subprogram): In case of dispatching operations, do not generate
15585 code to register the operation in the dispatch table if the source
15586 is compiled with No_Dispatching_Calls.
15587 (Register_Predefined_DT_Entry): Generate code that calls the new
15588 run-time subprogram Set_Predefined_Prim_Op_Address instead of
15589 Set_Prim_Op_Address.
15591 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
15592 on array assignments if the right-hand side is a function call that has
15593 been inlined. Check is performed on the assignment in the block.
15594 (Process_Bounds): If bounds and range are overloaded, apply preference
15595 rule for root operations to disambiguate, and diagnose true ambiguity.
15596 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
15597 a tag-indeterminate right-hand side even when Expander_Active is True.
15598 Needed to ensure that dispatching calls to T'Input are allowed and
15599 get the tag of the target class-wide object.
15601 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
15602 an inherited primitive operation that already overrides several
15603 abstract interface primitives. For transitivity, the new entity must
15604 also override all the abstract interface primitives covered by the
15605 inherited overriden primitive.
15606 Emit warning if new entity differs from homograph in same scope only in
15607 that one has an access parameter and the other one has a parameter of
15608 a general access type with the same designated type, at the same
15609 position in the signature.
15610 (Make_Inequality_Operator): Use source locations of parameters and
15611 subtype marks from corresponding equality operator when creating the
15612 tree structure for the implicit declaration of "/=". This does not
15613 change anything in behaviour except that the decoration of the
15614 components of the subtree created for "/=" allows ASIS to get the
15615 string images of the corresponding identifiers.
15616 (Analyze_Return_Statement): Remove '!' in warning message.
15617 (Check_Statement_Sequence): Likewise.
15618 (Analyze_Subprogram_Body): For an access parameter whose designated type
15619 is an incomplete type imported through a limited_with clause, use the
15620 type of the corresponding formal in the body.
15621 (Check_Returns): Implicit return in No_Return procedure now raises
15622 Program_Error with a compile time warning, instead of beging illegal.
15623 (Has_Single_Return): Function returning unconstrained type cannot be
15624 inlined if expression in unique return statement is not an identifier.
15625 (Build_Body_To_Inline): It is possible to inline a function call that
15626 returns an unconstrained type if all return statements in the function
15627 return the same local variable. Subsidiary procedure Has_Single_Return
15628 verifies that the body conforms to this restriction.
15630 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
15631 same type, and one of them is of an anonymous access type, convert
15632 the other operand to it, so that this is a valid binary operation for
15634 (Resolve_Type_Conversion): Handle subtypes of protected types and
15635 task types when accessing to the corresponding record type.
15636 (Resolve_Allocator): Add '\' in 2-line warning message.
15637 Remove '!' in warning message.
15638 (Resolve_Call): Add '\' in 2-line warning message.
15639 (Valid_Conversion): Likewise.
15640 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
15641 resulting type may be an access type with an implicit dereference.
15642 Obtain the proper component from the designated type.
15643 (Make_Call_Into_Operator): Handle properly a call to predefined equality
15644 given by an expanded name with prefix Standard, when the operands are
15645 of an anonymous access type.
15646 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
15647 Explicit_Dereference and Resolve_Selected_Component, to verify that the
15648 prefix of the expression is not of an incomplete type. Allows full
15649 diagnoses of all semantic errors.
15650 (Resolve_Actuals): If the actual is an allocator whose directly
15651 designated type is a class-wide interface we build an anonymous
15652 access type to use it as the type of the allocator. Later, when
15653 the subprogram call is expanded, if the interface has a secondary
15654 dispatch table the expander will add a type conversion to force
15655 the displacement of the pointer.
15656 (Resolve_Call): If a function that returns an unconstrained type is
15657 marked Inlined_Always and inlined, the call will be inlined and does
15658 not require the creation of a transient scope.
15659 (Check_Direct_Boolean_Op): Removed
15660 (Resolve_Comparison_Op): Remove call to above
15661 (Resolve_Equality_Op): Remove call to above
15662 (Resolve_Logical_Op): Inline above, since this is only call.
15663 (Valid_Conversion): Handle properly conversions between arrays of
15664 convertible anonymous access types.
15667 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
15668 the literal in an unchecked conversion, because GCC 4.x needs a static
15669 value for a string bound.
15671 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15672 Hristian Kirtchev <kirtchev@adacore.com>
15674 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
15675 components of the corresponding record, take into account component
15676 definitions that are access definitions.
15677 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
15678 procedure is not considered a dispatching call and will be expanded
15681 2006-02-13 Javier Miranda <miranda@adacore.com>
15683 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
15684 controlling argument of the dispatching call is an abstract interface
15685 class-wide type then we use it directly.
15686 Check No_Dispatching_Calls restriction.
15687 (Default_Prim_Op_Position): Remove the code that looks for the last
15688 entity in the list of aliased subprograms. This code was wrong in
15690 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
15691 when the source is compiled with the No_Dispatching_Calls restriction.
15692 (Init_Predefined_Interface_Primitives): No need to inherit primitives
15693 if we are compiling with restriction No_Dispatching_Calls.
15694 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
15695 subprograms if we are compiling under No_Dispatching_Calls restriction.
15696 (Make_DT): Generate a dispatch table with a single dummy entry if
15697 we are compiling with the No_Dispatching_Calls restriction. In
15698 addition, in this case we don't generate code that calls to the
15699 following run-time subprograms: Set_Type_Kind, Inherit_DT.
15700 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
15701 of this subprogram if compiling with the No_Dispatching_Calls
15703 (Expand_Type_Conversion): Instead of using the actual parameter,
15704 the argument passed as parameter to the conversion function was
15705 erroneously referenced by the expander.
15706 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
15707 Set_Predefined_Primitive_Op_Address and Set_Signature.
15708 (Expand_Dispatching_Call): Generate call to
15709 Get_Predefined_Prim_Op_Address for predefined primitives.
15710 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
15711 predefined primitives.
15712 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
15713 primitives we reserve one dummy entry to ensure that the tag does not
15714 point to some memory that is associated with some other object. In
15715 addition, remove all the old code that generated the assignments
15716 associated with the signature of the dispatch table and replace them
15717 by a call to the new subprogram Set_Signature.
15718 (Set_All_DT_Position): Change the algorithm because now we have a
15719 separate dispatch table associated with predefined primitive operations.
15720 (Expand_Interface_Conversion): In case of non-static offset_to_top
15721 add explicit dereference to get access to the object after the call
15722 to displace the pointer to the object.
15723 (Expand_Interface_Thunk): Modify the generation of the actual used
15724 in the calls to the run-time function Offset_To_Top to fulfil its
15726 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
15728 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15730 * exp_dist.adb (Copy_Specification): For access parameters, copy
15731 Null_Exclusion flag, which will have been set for stream subprograms
15734 2006-02-13 Pascal Obry <obry@adacore.com>
15736 * expect.c (__gnat_expect_portable_execvp): New implementation. The
15737 previous implementation was using the C runtime spawnve routine but
15738 the corresponding wait was using directly the Win32 API. This was
15739 causing some times a lock when waiting for an event using
15740 WaitForSingleObject in __gnat_waitpid. This new implementation uses
15741 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
15742 API fixes this problem.
15744 2006-02-13 Robert Dewar <dewar@adacore.com>
15746 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

15754 array reference that is an explicit dereference, mark the converted
15755 (packed) array reference as analyzed to prevent a forthcoming
15756 reanalysis from resetting its type to the original (non-packed) array
15759 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15760 Javier Miranda <miranda@adacore.com>
15761 Eric Botcazou <ebotcazou@adacore.com>
15763 * exp_util.ads, exp_util.adb (Find_Prim_Op,
15764 Is_Predefined_Primitive_Operation): When
15765 searching for the predefined equality operator, verify that operands
15766 have the same type.
15767 (Is_Predefined_Dispatching_Operation): Remove the code that looks
15768 for the last entity in the list of aliased subprograms. This code
15769 was wrong in case of renamings.
15770 (Set_Renamed_Subprogram): New procedure
15771 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
15772 Exp_Type constant computed when entering this subprogram.
15773 (Known_Null): New function
15774 (OK_To_Do_Constant_Replacement): New function
15775 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
15776 (Side_Effect_Free): An attribute reference 'Input is not free of
15777 side effect, unlike other attributes that are functions. (from code
15779 (Remove_Side_Effects): Expressions that involve packed arrays or records
15780 are copied at the point of reference, and therefore must be marked as
15781 renamings of objects.
15782 (Is_Predefined_Dispatching_Operation): Return false if the operation is
15783 not a dispatching operation.
15786 (Remove_Side_Effects): Lift enclosing type conversion nodes for
15787 elementary types in all cases.
15789 2006-02-13 Javier Miranda <miranda@adacore.com>
15791 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
15792 task types when accessing to the corresponding record type.
15793 Remove '!' in warning message.
15795 2006-02-13 Olivier Hainque <hainque@adacore.com>
15797 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
15798 to avoid useless and space inefficient overalignments on targets where
15799 Max_Alignment is larger than 16.
15801 2006-02-13 Pascal Obry <obry@adacore.com>
15803 * g-catiio.adb (Sec_Number): New type used to compute the number of
15804 seconds since 1-1-1970.
15805 (Image) [Natural]: The parameter was an Integer, as we can't deal with
15806 negative numbers (years, months...) it is better to have a Natural here.
15808 (Image) [Number]: Change parameter from Long_Integer to Number.
15809 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
15810 overflow for dates past year 2038.
15812 2006-02-13 Matthew Heaney <heaney@adacore.com>
15814 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
15817 2006-02-13 Arnaud Charlet <charlet@adacore.com>
15819 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
15821 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
15822 finalization can occur normally.
15824 2006-02-13 Vincent Celier <celier@adacore.com>
15826 * gnatcmd.adb (Rules_Switches): New table
15827 (Add_To_Rules_Switches): New procedure
15828 (GNATCmd): For command CHECK, put all options following "-rules" in the
15829 Rules_Switches table. Append these -rules switches after the -cargs
15832 2006-02-13 Robert Dewar <dewar@adacore.com>
15834 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
15835 These two cases were generating incorrect output, and if this unit
15836 was built with checks on, generated a discriminant mismatch constraint
15839 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15840 Robert Dewar <dewar@adacore.com>
15842 * lib-xref.adb (Get_Type_Reference): For a private type whose full
15843 view is an array type, indicate the component type as well, for
15844 navigation purposes.
15845 (Generate_Reference): Don't consider array ref on LHS to be a case
15846 of violating pragma Unreferenced.
15847 Do not give Ada 2005 warning except on real reference.
15849 2006-02-13 Vincent Celier <celier@adacore.com>
15851 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
15852 main source, add switch -mdebug-main=_ada_ so that the executable can
15853 be debugged by the standard VMS debugger.
15854 (Gnatmake): Set No_Main_Subprogram to True when there is no main
15855 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
15856 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
15857 of the last source, as the binding and linking phases are never
15859 Set all executable obsolete when rebuilding a library.
15861 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
15864 2006-02-13 Javier Miranda <miranda@adacore.com>
15867 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
15868 code to improve the error message reported when the program has
15869 declarations of abstract interface types and it is not compiled with
15870 the -gnat05 switch.
15871 (P_Access_Definition): Reorganize the code to improve the error
15872 message reported when the new Ada 2005 syntax for anonymous
15873 access types is used and the program is not compiled with the
15876 2006-02-13 Robert Dewar <dewar@adacore.com>
15878 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,
15879 stylesw.ads, usage.adb, vms_data.ads: Implement -gnatyI switch
15882 2006-02-13 Javier Miranda <miranda@adacore.com>
15884 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser

15887 2006-02-13 Vincent Celier <celier@adacore.com>
15889 * prj.adb (Reset): Initialize the first element of table Namings with
15890 the standard naming data.
15892 2006-02-13 Vincent Celier <celier@adacore.com>
15894 * prj.ads (Error_Warning): New enumeration type
15896 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
15897 unknown, use the location of the project to report the error.
15898 (When_No_Sources): New global variable
15899 (Report_No_Ada_Sources): New procedure
15900 (Check): New parameter When_No_Sources. Set value of global variable

15904 (Warn_If_Not_Sources): Better warning messages indicating the unit name
15907 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.

15910 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
15911 Call Recursive_Check with parameter When_No_Sources.
15912 (Recursive_Check): New parameter When_No_Sources. Call itself and
15913 Prj.Nmsc.Check with parameter When_No_Sources.
15914 (Process): New parameter When_No_Sources. Call Check with parameter
15916 (Copy_Package_Declarations): New procedure to copy renamed parameters
15917 and setting the location of the declared attributes to the location
15918 of the renamed package.
15919 (Process_Declarative_Items): Call Copy_Package_Declarations for renamed
15922 2006-02-13 Vincent Celier <celier@adacore.com>
15924 * prj-makr.adb (Make): Preserve the comments from the original project
15926 When removing nodes (attributes Source_Dirs, Source_Files,
15927 Source_List_File and package Naming), save the comments and attach the
15928 saved comments to the newly created nodes.
15929 Do not add a with clause for the naming package if one already exists.

15937 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
15938 aliased entities to look for the overriden abstract interface
15940 (Is_Interface_Subprogram): Complete documentation.
15941 (Check_Dispatching_Operation): Do not generate code to register the
15942 operation in the dispatch table if the source is compiled with
15943 restriction No_Dispatching_Calls.
15944 (Override_Dispatching_Operation): Check for illegal attempt to override
15945 No_Return procedure with procedure that is not No_Return
15946 (Check_Dispatching_Call): Suppress the check for an abstract operation
15947 when the original node of an actual is a tag-indeterminate attribute
15948 call, since the attribute, which must be 'Input, can never be abstract.
15949 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
15950 call to the Input attribute (even when rewritten).
15951 (Propagate_Tag): Augment comment to indicate the possibility of a call
15952 to an Input attribute.
15954 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
15955 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
15957 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
15958 No_Wide_Characters is no longer partition-wide
15959 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
15962 2006-02-13 Douglas Rupp <rupp@adacore.com>
15964 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
15966 2006-02-13 Javier Miranda <miranda@adacore.com>
15968 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
15969 handles default-initialized components to keep separate the management
15970 of this feature but also avoid the unrequired resolution and
15971 expansion of components that do not have partially initialized
15973 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
15974 (Check_Bounds): Likewise.
15975 (Check_Length): Likewise.
15977 2006-02-13 Javier Miranda <miranda@adacore.com>
15978 Ed Schonberg <schonberg@adacore.com>
15980 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
15981 abstract interface type call analyze_and_resolve to expand the type
15982 conversion into the corresponding displacement of the
15983 reference to the base of the object.
15984 (Eval_Attribute, case Width): For systems where IEEE extended precision
15985 is supported, the maximum exponent occupies 4 decimal digits.
15986 (Accessibility_Message): Add '\' in 2-line warning message.
15987 (Resolve_Attribute): Likewise.
15988 (case Attribute_Access): Significantly revise checks
15989 for illegal access-to-subprogram Access attributes to properly enforce
15990 the rules of 3.10.2(32/2).
15991 Diagnose use of current instance with an illegal attribute.
15993 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
15995 (Enclosing_Generic_Unit): New function to return a node's innermost
15996 enclosing generic declaration node.
15997 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
15998 (Type_Access_Level): The accessibility level of anonymous acccess types
15999 associated with discriminants is that of the current instance of the
16000 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
16001 (Compile_Time_Constraint_Error): Handle case of conditional expression.
16002 (Kill_Current_Values_For_Entity): New function
16003 (Enter_Name): Change formal type to Entity_Id
16005 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
16006 Ed Schonberg <schonberg@adacore.com>
16007 Gary Dismukes <dismukes@adacore.com>
16009 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
16010 Analyze_Compilation_Unit.
16011 Detect and warn on redundant with clauses detected in a package spec
16012 and/or body when -gnatwr is used.
16013 (Analyze_Context): Analyze config pragmas before other items
16014 (Install_Context_Items): Don't analyze config pragmas here
16015 (Install_Limited_Withed_Unit): Set limited entity of package in
16016 with_clause so that cross-reference information or warning messages on
16017 unused packages can be properly generated
16018 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
16019 has Error_Posted set. Prevent infinite loops in illegal programs.
16020 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
16021 to the point of the error test requiring the current unit to be private.
16022 This ensures that private with clauses are not exempted from the basic
16023 checking for being a descendant of the same library unit parent as a
16024 withed private descendant unit.
16025 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
16026 handle private with clauses properly, as well as to account for cases
16027 where the withed unit is a public descendant of a private ancestor
16028 (in which case the current unit must be a descendant of the private
16029 ancestor's parent). The spec comments were updated accordingly. Also,
16030 the old error message in this subprogram was replaced with error
16031 messages that mirror the errors tested and reported by
16032 Check_Private_Child_Unit.
16033 Parameter and variable names improved for readability.
16034 (Install_Limited_Context_Clauses): Remove test for a withed unit being
16035 private as the precondition for calling
16036 Check_Private_Limited_Withed_Unit since that subprogram has been
16037 revised to test public units as well as private units.

16041 Ed Schonberg <schonberg@adacore.com>
16042 Javier Miranda <miranda@adacore.com>
16044 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
16045 that Scope_Stack.First = 1.
16046 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
16047 were not always properly handled previously.
16048 (Formal_Entity): Complete rewrite, to handle properly some complex case
16049 with multiple levels of parametrization by formal packages.
16050 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
16051 to the corresponding derived type declaration for proper semantics.
16053 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
16054 (Check_Component): Enforce restriction on components of
16055 unchecked_unions: a component in a variant cannot contain tasks or
16057 (Unchecked_Union): Allow nested variants and multiple discriminants, to
16059 Add pragma Ada_2005 (synonym for Ada_05)
16060 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
16061 were not always properly handled previously.
16062 Document that pragma Propagate_Exceptions has no effect
16063 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
16064 (Set_Convention_From_Pragma): Check that if a convention is
16065 specified for a dispatching operation, then it must be
16066 consistent with the existing convention for the operation.
16067 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
16068 longer required to specify an vtable-ptr component in the record. For
16069 compatibility reasons we leave the support for the previous definition.
16070 (Analyze_Pragma, case No_Return): Allow multiple arguments
16072 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
16073 non-overrideen inherited operation with a controlling result as
16074 illegal only its implicit declaration comes from the derived type
16075 declaration of its result's type.
16076 (Check_Possible_Deferred_Completion): Relocate the object definition
16077 node of the subtype indication of a deferred constant completion rather
16078 than directly analyzing it. The analysis of the generated subtype will
16079 correctly decorate the GNAT tree.
16080 (Record_Type_Declaration): Check whether this is a declaration for a
16081 limited derived record before analyzing components.
16082 (Analyze_Component_Declaration): Diagnose record types not explicitly
16083 declared limited when a component has a limited type.
16084 (Build_Derived_Record_Type): Code reorganization to check if some of
16085 the inherited subprograms of a tagged type cover interface primitives.
16086 This check was missing in case of a full-type associated with a private
16088 (Constant_Redeclaration): Check that the subtypes of the partial and the
16089 full view of a constrained deferred constant statically match.
16090 (Mentions_T): A reference to the current type in an anonymous access
16091 component declaration must be an entity name.
16092 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
16093 class_wide type to refer to full type, not to the incomplete one.
16094 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
16095 available. Required to give support to the certified run-time.
16096 (Analyze_Component_Declaration): In case of anonymous access components
16097 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
16098 (Process_Discriminants): For an access discriminant, use the
16099 discriminant specification as the associated_node_for_itype, to
16100 simplify accessibility checks.
16102 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16103 Javier Miranda <miranda@adacore.com>
16105 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
16106 abstract interpretations on an operator, remove interpretations that
16107 yield Address or a type derived from it, if one of the operands is an
16109 (Try_Object_Operation.Try_Primitive_Operation,
16110 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
16111 location when creating the new reference to a primitive or class-wide
16112 operation as a part of rewriting a subprogram call.
16113 (Try_Primitive_Operations): If context requires a function, collect all
16114 interpretations after the first match, because there may be primitive
16115 operations of the same type with the same profile and different return
16116 types. From code reading.
16117 (Try_Primitive_Operation): Use the node kind to choose the proper
16118 operation when a function and a procedure have the same parameter
16120 (Complete_Object_Operation): If formal is an access parameter and prefix
16121 is an object, rewrite as an Access reference, to match signature of
16122 primitive operation.
16123 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
16124 by an expanded name with prefix Standard, when the operands are of an
16125 anonymous access type.
16126 (Remove_Abstract_Operations): If the operation is abstract because it is
16127 inherited by a user-defined type derived from Address, remove it as
16128 well from the set of candidate interpretations of an overloaded node.
16129 (Analyze_Membership_Op): Membership test not applicable to cpp-class
16132 2006-02-13 Bob Duff <duff@adacore.com>
16134 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
16135 redundant use clauses.
16136 In particular, if the scope of two use clauses overlaps, but one is not
16137 entirely included in the other, we should not warn. This can happen
16138 with nested packages.
16139 (Analyze_Subprogram_Renaming): Protect the compiler against previously
16140 reported errors. The bug was reported when the compiler was built
16141 with assertions enabled.
16142 (Find_Type): If the node is a 'Class reference and the prefix is a
16143 synchronized type without a corresponding record, return the type
16146 2006-02-13 Javier Miranda <miranda@adacore.com>
16148 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
16149 if this is the full-declaration associated with a private declaration
16150 that implement interfaces, then the private type declaration must be
16152 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
16153 as aliased. The use of the 'access attribute is not available for such
16154 object (for this purpose the object should be explicitly marked as
16155 aliased, but being an anonymous type this is not possible).
16157 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16158 Robert Dewar <dewar@adacore.com>
16160 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
16161 compilation unit is an elaboration scope.
16162 (Add_Task_Proc): Add '\' in 2-line warning message.
16163 (Activate_All_Desirable): Deal with case of unit with'ed by parent
16165 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16166 Javier Miranda <miranda@adacore.com>
16168 * sem_type.adb (Write_Overloads): Improve display of candidate
16170 (Add_One_Interp): Do not add to the list of interpretations aliased
16171 entities corresponding with an abstract interface type that is an
16172 immediate ancestor of a tagged type; otherwise we have a dummy
16173 conflict between this entity and the aliased entity.
16174 (Disambiguate): The predefined equality on universal_access is not
16175 usable if there is a user-defined equality with the proper signature,
16176 declared in the same declarative part as the designated type.
16177 (Find_Unique_Type): The universal_access equality operator defined under
16178 AI-230 does not cover pool specific access types.
16179 (Covers): If one of the types is a generic actual subtype, check whether
16180 it matches the partial view of the other type.
16182 2006-02-13 Thomas Quinot <quinot@adacore.com>
16184 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
16185 line. This is necessary to allow In_Extended_Main_Unit to provide
16186 correct results for itypes while writing out expanded source.
16187 (Close_File): No need to update the source_index_table here since it's
16188 now done for each line.
16190 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16191 Robert Dewar <dewar@adacore.com>
16193 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
16194 preserve the source unit where the itype is declared, and prevent a
16196 (Note_Implicit_Run_Time_Call): New procedure
16197 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
16200 * sprint.ads: Document use of $ for implicit run time routine call
16202 2006-02-13 Quentin Ochem <ochem@adacore.com>
16204 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
16207 2006-02-13 Bob Duff <duff@adacore.com>
16209 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
16210 Scan_Unsigned, so we do not scan leading blanks and sign twice.
16211 Integer'Value("- 5") and Integer'Value("-+5") now correctly
16212 raise Constraint_Error.
16214 * s-vallli.adb (Scan_Long_Long_Integer): Call
16215 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
16216 do not scan leading blanks and sign twice.
16217 Integer'Value("- 5") and Integer'Value("-+5") now correctly
16218 raise Constraint_Error.
16220 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
16221 Scan_Long_Long_Unsigned): Split out most of the processing from
16222 Scan_Long_Long_Unsigned out into
16223 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
16224 This prevents scanning leading blanks and sign twice.
16225 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
16228 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
16229 out most of the processing from Scan_Unsigned out into
16230 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
16231 This prevents scanning leading blanks and sign twice.
16233 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
16234 use with Modular'Value attribute.
16235 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
16238 2006-02-13 Robert Dewar <dewar@adacore.com>
16240 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
16242 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
16244 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
16245 (PPC VxWorks): Likewise.
16246 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
16247 (forced_callee): Make non-inlinable and non-pure.
16248 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

16251 Ben Brosgol <brosgol@adacore.com>
16252 Robert Dewar <dewar@adacore.com>
16254 * gnat_rm.texi, gnat_ugn.texi: Remove limitations with sparc m64
16256 Document that gnatbind -M option is for cross environments only.

16361 Targparm.OpenVMS_On_Target.
16362 (Object_Suffix): Initialize with call to Get_Target_Object_Suffix.
16363 ({declaraction},Delete_Binder_Generated_Files,{initialization}): Change
16364 Ada bind file prefix on VMS from b$ to b__.
16366 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
16367 --GCC so that Get_Target_Parameters can find system.ads.
16368 (Gnatlink): Call Get_Target_Parameters in mainline.
16369 Initialize standard packages for Targparm.
16370 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

16389 * Makefile.in: add support for vxworks653 builds
16390 (../../vxaddr2line): gnatlink with targext.o.
16391 (TOOLS_LIBS): Move targext.o to precede libgnat.
16392 (init.o, initialize.o): Minor clean up in dependencies.
16393 (GNATLINK_OBJS): Add targparm.o, snames.o
16394 Add rules fo building targext.o and linking it explicitly with all
16396 Also add targext.o to gnatlib.

16430 Quentin Ochem <ochem@adacore.com>
16431 Florian Villoing <villoing@adacore.com>
16433 * a-taster.ads, a-taster.adb: New files.
16435 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
16436 link to the version that does nothing. This way the task termination
16437 routine is not executed twice for the environment task when finishing
16438 because of an unhandled exception.
16440 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
16441 handler because of an unhandled exception.
16443 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
16444 System.Tasking.Utilities instead of that in System.Tasking.Stages.
16446 * s-finimp.adb (initialization code): Modify the soft link for the
16447 finalization of the global list instead of Adafinal.
16449 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
16450 non-tasking version of the soft link for task termination. We do
16451 nothing since if we are using the non-tasking version it
16452 means that the task termination functionality is not used.
16453 (Null_Finalize_Global_List): Add this null version for the procedure
16454 in charge of finalizing the global list for controlled objects.
16455 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
16456 instead for handling run-time termination in a more flexible way.
16457 (Adafinal_NT): This new procedure will take care of finalizing the
16458 global list for controlled objects if needed, but no tasking
16461 * s-tarest.adb (Task_Lock): Do not try to lock again the
16462 Global_Task_Lock if we already own it. Otherwise, we get blocked in
16463 some run-time operations.
16464 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
16465 until all nested locks have been released.
16466 (Task_Wrapper): Call the fall-back task termination handler. It
16467 applies to all tasks but the environment task.
16468 (Finalize_Global_Tasks): Add the call for the task termination
16469 procedure for the environment task.
16470 (Task_Wrapper): suppress warnings around declaration of
16471 Secondary_Stack_Address.
16473 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
16474 moved to the Common_ATCB record.
16475 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
16476 Common_ATCB record.
16477 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
16478 Common_ATCB record.
16480 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
16481 Fall_Back_Handler, and Specific_Handler.
16483 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
16484 defined in Ada.Task_Termination, to avoid circular dependencies.
16485 (Termination_Handler): Redefine this type here, alredy defined in
16486 Ada.Task_Termination, for avoiding circular dependencies.
16487 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
16488 for storing task termination handlers. In addition,
16489 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
16490 Common_ATCB because it is used by both the regular and the restricted
16492 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
16493 Common_ATCB because it is used by both the regular and the restricted
16495 (Common_ATCB): Added a dynamic task analyzer field.
16497 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
16498 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
16499 (Task_Wrapper): Call the task termination handler. It applies to all
16500 tasks but the environment task.
16501 (Finalize_Global_Tasks): Call the task termination procedure for the
16502 environment task. The call to Finalize_Global_List is now performed
16503 using the soft links mechanism.
16504 (Task_Wrapper): added dynamic stack analysis.
16506 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
16507 potentially blocking operations has been moved from
16508 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
16509 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
16510 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
16511 this run-time check.
16513 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
16514 of task termination procedure.
16515 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
16516 link for the task termination procedure.
16518 * bindusg.adb: (Bindusg): Added documentation for -u option.

16562 (Displace): New subprogram that displaces the pointer to the object
16563 to reference one of its secondary dispatch tables.
16564 (IW_Membership): Modified to use the new table of interfaces.
16565 (Inherit_TSD): Modified to use the new table of interfaces.

16586 have to use the Offset_To_Top run-time function to get this information;
16587 otherwise if the pointer to the base of the object has been displace
16588 we get a wrong value if we use the 'position attribute.
16590 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
16591 all the calls to Expand_Interface_Thunk.

16626 RE_TK_Tagged, RE_TK_Task.
16628 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
16629 Init_Secondary_Tags_Internal to allow its use with interface types and
16630 also to generate the code for the new additional actual required
16631 by Set_Offset_To_Top.
16632 (Build_Init_Statements): In case of components associated with abstract
16633 interface types there is no need to generate a call to its IP.

16660 pointer initialization values. Make a SAVE_EXPR instead. Add comments
16661 about the use and expansion of SAVE_EXPRs in the various possible
16662 renaming handling cases.
16663 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by

16834 are implemented by the ancestors.
16835 (Derived_Type_Declaration): If the parent of the full-view is an
16836 interface perform a transformation of the tree to ensure that it has
16837 the same parent than the partial-view. This simplifies the job of the
16838 expander in order to generate the correct object layout, and it is
16839 needed because the list of interfaces of the full-view can be given in
16841 (Process_Full_View): The parent of the full-view does not need to be
16842 a descendant of the parent of the partial view if both parents are
16844 (Analyze_Private_Extension_Declaration): If declaration has an explicit
16845 "limited" the parent must be a limited type.

16922 attributes are visible at the point of the subprogram declaration.
16923 For Ada 2005, the error message is modified to indicate that the

17182 TARGET, as it has the form of a math expression, and some components
17183 may be platform-defined macros.
17184 For VxWorks, generate the OK and ERROR values.
17185 New constants giving the sizes of the components of C struct timeval.

17197 deal with different cases of static and dynamic elaboration checks (all
17198 checks does not count in the first case, but does in the second).

17204 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
17205 elementary types using the operator in standard. It is cleaner not to
17206 modify the programmers intent, especially in the case of floating-point.
17207 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
17208 it did not matter because we always rewrote a/=b to not(a=b).
17209 (Expand_Allocator_Expression): For an allocator expression whose nominal
17210 subtype is an unconstrained packed type, convert the expression to its
17211 actual constrained subtype.
17212 Implement warning for <= or >= where < or > not possible
17213 Fix to Vax_Float tests (too early in many routines, causing premature
17214 Vax_Float expansions.
17216 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
17217 to be used with packages and generic packages as well as with

17220 of pragma Suppress (All_Checks)
17221 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
17222 a string literal for precise control over warnings.

17228 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
17229 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

17232 Allow optional = after -gnatm
17233 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
17234 longer sets Elaboration_Checks.
17235 Code to set warning mode moved to Sem_Warn
17236 so that it can be shared by pragma processing.
17238 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
17241 * s-taprop-solaris.adb:
17242 Change some <= to =, to avoid new warning

17248 2005-11-14 Robert Dewar <dewar@adacore.com>
17250 * exp_vfpt.adb: Handle /= case
17251 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
17252 so that we do not get duplicate scaling for fixed point conversions.
17254 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
17256 2005-11-14 Matthew Gingell <gingell@adacore.com>
17258 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
17259 Increase default priority on Lynx from 15 to 17, and meet the Ada
17260 requirement that Default_Priority be ((Priority'First +
17261 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

17358 from a fat or thin pointer type and a constrained object type.
17359 (annotate_value): Handle BIT_AND_EXPR.
17360 (annotate_rep): Don't restrict the back annotation of inherited
17361 components to the type_annotate_only case.
17362 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
17363 we are not defining the type.
17364 <E_Record_Type>: Likewise.
17365 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
17366 to get advantage of the new maybe_stabilize_reference interface, to
17367 ensure that what we reference is indeed stabilized instead of relying
17368 on assumptions on what the stabilizer does.
17369 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
17370 type imported through a limited_with clause, use its non-limited view.
17371 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
17373 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
17374 of #if sections + explicit comparisons of convention identifiers.
17375 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
17376 before early-returning for certain types when code generation is
17378 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
17379 nullification of gnu_expr we do for objects with address clause and
17380 that we are not defining.
17381 (elaborate_expression_1): Do not create constants when creating
17382 variables needed by the debug info: the dwarf2 writer considers that
17383 CONST_DECLs is used only to represent enumeration constants, and emits
17385 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
17386 object with an address clause into an indirect reference, drop the
17387 initializing expression.
17389 (STACK_CHECK_BUILTIN): Delete.
17390 (STACK_CHECK_PROBE_INTERVAL): Likewise.

17397 related): For a prefix that is a dereference of a fat or thin pointer,
17398 if there is an actual subtype provided by the front-end, use that
17399 subtype to build an actual type with bounds template.
17400 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
17401 is provided by the front-end, use that subtype to compute the size of
17402 the deallocated object.
17403 (gnat_to_gnu): When adding a statement into an elaboration procedure,
17404 check for a potential violation of a No_Elaboration_Code restriction.
17405 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
17406 with extra arguments to control whether to recurse through non-values
17407 and to let the caller know if the stabilization has succeeded.

17409 maybe_stabilize, for common uses without restriction on lvalues and
17410 without need to check for the success indication.
17411 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
17412 pass false instead of 0 as the FORCE argument which is a bool.
17413 (Identifier_to_gnu): Remove checks ensuring that an renamed object
17414 attached to a renaming pointer has been properly stabilized, as no such
17415 object is attached otherwise.
17416 (call_to_gnu): Invoke create_var_decl to create the temporary when the
17417 function uses the "target pointer" return mechanism.
17418 Reinstate conversion of the actual to the type of the formal
17419 parameter before any other specific treatment based on the passing
17420 mechanism. This turns out to be necessary in order for PLACEHOLDER
17421 substitution to work properly when the latter type is unconstrained.
17423 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
17425 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
17426 with extra arguments to control whether to recurse through non-values
17427 and to let the caller know if the stabilization has succeeded.
17429 * utils2.c (gnat_build_constructor): Only sort the fields for possible
17430 static output of record constructor if all the components are constant.
17431 (gnat_build_constructor): For a record type, sort the list of field
17432 initializers in increasing bit position order.
17433 Factor common code to build a storage type for an unconstrained object
17434 from a fat or thin pointer type and a constrained object type.
17435 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
17436 types variants, and process special cases of VIEW_CONVERT expressions
17437 as their NOP_EXPR counterpart to ensure we get to the
17438 CORRESPONDING_VARs associated with CONST_DECls.
17439 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
17440 on the right-hand side.
17442 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
17444 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
17445 are converting back to its original type.
17446 (convert) <JM input>: Fallthrough regular conversion code instead of
17447 extracting the object if converting to a type variant.
17448 (create_var_decl): When a variable has an initializer requiring code
17449 generation and we are at the top level, check for a potential violation
17450 of a No_Elaboration_Code restriction.
17451 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
17452 SIZE and SIZE_UNIT which we need for later back-annotations.
17453 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
17454 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
17455 is an unchecked union.
17456 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
17457 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
17458 main variant, just replace the VIEW_CONVERT_EXPR.
17459 <UNION_TYPE>: Revert 2005-03-02 change.

17643 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
17644 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
17645 'Terminated for task interface class-wide objects. Generate a call to
17646 the predefined dispatching routine used to retrieve the _task_id from

17676 the return value into its actual subtype in order to help the backend

17727 attribute of the N_Free_Statement.
17728 Generate itype for classwide designated object in both cases of

17969 not already set. Replace test of Is_Child_Unit with test of parent's
17970 scope against package Standard. Add comments and a ??? comment.
17971 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
17972 on a child instance parent to test that the parent equals

17987 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
17989 (Build_Private_Derived_Type): The entity of the created full view of the
17990 derived type does not come from source. If after installing the private
17991 declarations of the parent scope the parent is still private, use its
17992 full view to construct the full declaration of the derived type.
17993 (Build_Derived_Record_Type): Relax the condition that controls the
17994 execution of the check that verifies that the partial view and
17995 the full view agree in the set of implemented interfaces. In
17996 addition, this test now only takes into account the progenitors.
17997 (Derive_Interface_Subprograms): No need to derive subprograms
17998 of ancestors that are interfaces.

18003 view is a transitive derivation of the ancestor of the partial view.
18004 (Process_Full_View): Rename local subprogram Find_Interface_In_
18005 Descendant to Find_Ancestor_Interface to leave the code more clear.
18006 Remove wrong code that avoids the generation of an error message
18007 when the immediate ancestor of the partial view is an interface.
18008 In addition some minor reorganization of the code has been done to
18009 leave it more clear.
18010 (Analyze_Type_Declaration): If type has previous incomplete tagged
18011 partial view, inherit properly its primitive operations.

18024 and derived protected types, the parent may be an interface that must
18025 be included in the interface list.
18026 (Access_Definition): If the designated type is an interface that may
18027 contain tasks, create Master_Id for it before analyzing the expression
18028 of the declaration, which may be an allocator.
18029 (Record_Type_Declaration): Set properly the interface kind, for use
18030 in allocators, the creation of master id's for task interfaces, etc.

18056 Change name Is_Package to Is_Package_Or_Generic_Package
18057 (Preserve_Full_Attributes): For a synchronized type, the corresponding

18063 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
18064 not try to rewrite a renamed stream attribute, because the operations
18065 on the type may not have been generated.
18066 Handle properly a renaming_as_body generated for a stream operation
18067 whose default is abstract because the object type itself is abstract.
18068 (Find_Type): If the type is incomplete and appears as the prefix of a
18069 'Class reference, it is tagged, and its list of primitive operations
18070 must be initialized properly.
18071 (Chain_Use_Clauses): When chaining the use clauses that appear in the
18072 private declaration of a parent unit, prior to compiling the private
18073 part of a child unit, find on the scope stack the proper parent entity
18074 on which to link the use clause.
18075 (Note_Redundant_Use): Emit a warning when a redundant use clause is
18077 (Analyze_Object_Renaming): An attribute reference is not a legal object
18078 if it is not a function call.

18095 a procedure call is used as a select statement trigger and is not an
18096 entry renaming or a primitive of a limited interface.
18097 (Valid_Conversion): If the operand has a single interpretation do not
18098 remove address operations.
18099 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
18100 statement to inhibit warning.
18101 (Resolve_Unary_Op): Do not produce a warning when
18102 processing an expression of the form -(A mod B)
18103 Use Universal_Real instead of Long_Long_Float when we need a high
18104 precision float type for the generated code (prevents gratuitous
18105 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
18106 (Resolve_Concatenation_Arg): Improve error message when argument is an
18107 ambiguous call to a function that returns an array.
18108 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
18109 there is an implicit operator in the given scope if we are within an
18110 instance: legality check has been performed on the generic.

19065 * errutil.adb, erroutc.adb: Implement new insertion char <
19066 (conditional warning).
19067 * sem_elab.adb, prj-dect.adb, erroutc.ads, err_vars.ads
19068 (Error_Msg_Warn): New variable for < insertion char.
19069 * prj-nmsc.adb: Implement new errout insertion char < (conditional
19071 (Check_For_Source): Change value of Source_Id only after the current
19072 source has been dealt with.
19074 2005-09-01 Robert Dewar <dewar@adacore.com>
19075 Doug Rupp <rupp@adacore.com>
19077 * exp_attr.adb: Handle vax fpt for 'Valid attribute
19078 * exp_vfpt.ads, exp_vfpt.adb: (Expand_Vax_Valid): New procedure
19079 * s-vaflop-vms-alpha.adb, s-vaflop.ads, s-vaflop.adb
19080 (Valid_D, Valid_F, Valid_G): New functions
19082 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19083 Hristian Kirtchev <kirtchev@adacore.com>
19084 Javier Miranda <miranda@adacore.com>
19086 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
19087 from object notation, the original node is unanalyzed and carries no
19088 semantic information, so that accessiblity checks must be performed on
19089 the type of the actual itself.
19090 (Expand_N_Subprogram_Declaration): Change last actual parameter for
19091 compatibility with Build_Protected_Sub_Specification.
19092 (Check_Overriding_Inherited_Interfaces): Add suport to handle
19093 overloaded primitives.
19094 (Register_Interface_DT_Entry): Use the new name of the formal
19095 the the calls to Expand_Interface_Thunk
19097 * exp_dbug.ads: Augment comments on encoding of protected types to
19098 include the generation of dispatching subprograms when the type
19099 implements at least one interface.
19101 * lib.ads: Extend information in Load_Stack to include whether a given
19102 load comes from a Limited_With_Clause.
19104 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
19105 whether a potential circularity is harmless, because it includes units
19106 loaded through a limited_with clause. Extends previous treatment which
19107 did not handle properly arbitrary combinations of limited and
19108 non-limited clauses.
19110 2005-09-01 Nicolas Setton <setton@adacore.com>
19112 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
19113 to be encoded as typ___XBLU_lowerbound__upperbound instead of
19114 typ___XB_lowerbound__upperbound.
19116 2005-09-01 Thomas Quinot <quinot@adacore.com>
19118 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
19119 dummy access formal for RACW/RAS TypeCode TSS.
19120 (Build_TypeCode_Call): Do not generate dummy null access actual for
19121 calls to the TypeCode TSS.
19123 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19125 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
19126 fully qualified name, to distinguish instances with the same local name.
19128 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
19131 2005-09-01 Robert Dewar <dewar@adacore.com>

19136 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
19138 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
19139 (Free): New deallocation procedure for filter elements
19140 (Close): Deallocate any existing filter for the concerned connection
19142 2005-09-01 Laurent Pautet <pautet@adacore.com>
19144 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
19145 position set is provided, we compute one in order to reduce the maximum
19146 length of the keys. This computation first selects a character
19147 position between 1 and the minimum length of the keys in order to
19148 avoid reducing one of the keys to an empty string.
19149 (Initialize, Compute): When the ratio V to K is too low, the algorithm
19150 does not converge. The initialization procedure now comes with a
19151 maximum number of iterations such that when exceeded, an exception is
19152 raised in Compute. The user can initialize this ratio to another value
19154 Reformating and updated headers.
19156 2005-09-01 Javier Miranda <miranda@adacore.com>
19158 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
19159 that given an entity T creates and returns an Itype that duplicates the
19160 contents of T. The returned Itype has the null-exclusion
19161 attribute set to True, and its Etype attribute references T
19162 to keep the association between the two entities.
19163 Update copyright notice
19165 * sem_aggr.adb (Check_Can_Never_Be_Null,
19166 Aggregate_Constraint_Checks, Resolve_Aggregate,
19167 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
19169 * sem_ch5.adb (Analyze_Assignment): Code cleanup.
19171 2005-09-01 Gary Dismukes <dismukes@adacore.com>
19172 Robert Dewar <dewar@adacore.com>
19173 Hristian Kirtchev <kirtchev@adacore.com>
19175 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
19178 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
19180 Call Set_Result_Definition instead of Set_Subtype_Mark.
19181 (P_Subprogram_Specification): Add parsing of anonymous access result
19182 plus null exclusions. Call Set_Result_Definition instead of
19185 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
19186 (P_Access_Type_Definition): Add parsing for an anonymous access result
19187 subtype, plus parsing for null exclusions. Call Set_Result_Definition
19188 instead of Set_Subtype_Mark.
19190 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
19191 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
19192 (Result_Definition): New function for N_Function_Specifications.
19193 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
19194 N_Function_Specification.
19195 (Set_Null_Exclusion_Present): Allow this flag for
19196 N_Function_Specification.
19197 (Set_Result_Definition): New procedure for N_Function_Specifications.
19198 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
19199 and N_Function_Specification.
19201 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
19202 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
19203 Add support for LIMITED NEW for Ada 2005 AI-419
19204 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
19205 syntax for anonymous access results.
19206 Replace Subtype_Mark field by Result_Definition in
19207 N_Function_Specification and N_Access_Definition specs.
19208 Add Null_Exclusion_Present to spec of N_Function_Specification.
19209 (Result_Definition): New function for N_Function_Specification and
19210 N_Access_Function_Definition.
19211 (Set_Result_Definition): New procedure for N_Function_Specification and
19212 N_Access_Function_Definition.
19214 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
19215 Result_Definition for cases of N_Access_Function_Definition and
19216 N_Function_Specification.
19217 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
19219 2005-09-01 Vincent Celier <celier@adacore.com>
19221 * lib-writ.adb: Update Copyright notice
19222 (Write_With_Lines): On platforms where file names are case-insensitive,
19223 record the file names in lower case.
19224 (Write_ALI): For D lines, on platforms where file names are
19225 case-insensitive, record the file names in lower case.
19227 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19228 Emmanuel Briot <briot@adacore.com>
19230 * lib-xref.adb (Output_Overridden_Op): Display information on
19231 overridden operation.
19233 * lib-xref.ads: Add documentation on overridden operations.
19235 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
19238 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
19239 overriding entity information.
19241 2005-09-01 Vincent Celier <celier@adacore.com>
19243 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
19244 including those that are inherited.
19246 2005-09-01 Robert Dewar <dewar@adacore.com>
19248 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
19250 * par-prag.adb: Implement new pragma Debug_Policy
19252 * sem_prag.adb Implement new pragma Debug_Policy
19253 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
19254 Component_Size attribute specification. Give warning for ignored pragma
19257 * snames.h, snames.ads, snames.adb: Introduce entries in
19258 Preset_Names for Name_Disp_Asynchronous_Select,
19259 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
19260 Name_Disp_Timed_Select.
19261 New pragma Debug_Policy
19263 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
19265 Switch -gnata also sets Debug_Pragmas_Enabled
19267 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
19268 handle an explicit -gnata when compiling predefined files.
19270 2005-09-01 Vincent Celier <celier@adacore.com>
19272 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
19273 directories of projects that have no Ada sources.
19275 2005-09-01 Robert Dewar <dewar@adacore.com>
19277 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
19278 (makes a difference for wide characters)
19280 * widechar.adb, widechar.ads:
19281 Add Wide_Char_Byte_Count feature to count chars vs bytes
19283 2005-09-01 Thomas Quinot <quinot@adacore.com>
19284 Ed Schonberg <schonberg@adacore.com>
19285 Robert Dewar <dewar@adacore.com>
19287 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
19288 'Address attribute reference with an overloaded prefix, use the
19289 location of the prefix (not the location of the attribute reference) as
19290 the error location.
19291 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
19292 a function renaming thereof, is a valid prefix for 'Size (where it is
19293 intepreted as a function call).
19294 (Statically_Denotes_Entity): New predicate to determine whether the
19295 prefix of an array attribute can be considered static.
19298 (Eval_Attr): Fix failure to evaluate Component_Size for
19299 unconstrained arrays (resulted in wrong value in packed case, since
19300 back end cannot handle this case)
19302 2005-09-01 Robert Dewar <dewar@adacore.com>
19304 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
19305 error msgs for most common cases.
19306 Use new errout insertion char < (conditional warning)
19308 2005-09-01 Javier Miranda <miranda@adacore.com>
19309 Ed Schonberg <schonberg@adacore.com>
19311 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
19312 become local to the whole package.
19313 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
19314 the package was already analyzed the new algorithm "replaces" the
19315 real entities by the shadow ones. This is required to ensure that
19316 the order of these entities in the homonym chains does not change;
19317 otherwise we can have undefined references at linking time because
19318 in case of conflicts the external name of the entities will have
19319 a suffix that depends on the order of the entities in the chain.
19320 (Remove_Limited_With_Clause): Complementary code that completes the
19321 new algorithm and replaces the shadow entities by the real ones.
19322 (Install_Limited_Withed_Unit): When unchaining entities before the
19323 installation of the shadow entities, only regular entities of the
19324 public part must be taken into account. This is required to
19325 keep this routine in synch with the work done by Remove_Limited_
19327 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
19328 even if unit is analyzed, because the analysis of the unit is
19329 idempotent in any case, and the limited view of the unit may have to
19330 be installed for proper visibility.
19331 (Expand_Limited_With_Clause): Even if the unit in the implicit
19332 with_clause has been analyzed already, a limited view of the package
19333 must be built for the current context, if it does not exist yet.
19335 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19336 Javier Miranda <miranda@adacore.com>
19337 Gary Dismukes <dismukes@adacore.com>
19339 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
19340 defining entity for the instance body, make a new defining identifier
19341 rather than copying the entity of the spec, to prevent accidental
19342 sharing of the entity list.
19343 (Check_Private_View): When exchanging views of private types, build the
19344 list of exchanged views as a stack, to ensure that on exit the exchanges
19345 are undone in the proper order.
19346 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
19347 Restore the compilation environment in case of instantiation_error.
19348 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
19349 for an anonymous access result.
19350 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
19351 (Formal_Entity): Handle properly the case of a formal package that
19352 denotes a generic package renaming.
19354 2005-09-01 Thomas Quinot <quinot@adacore.com>
19356 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
19357 clause if the array aggregate is surrounded by parentheses.
19359 2005-09-01 Cyrille Comar <comar@adacore.com>
19360 Gary Dismukes <dismukes@adacore.com>
19361 Ed Schonberg <schonberg@adacore.com>
19362 Javier Miranda <miranda@adacore.com>
19364 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
19366 to check if a type is Constrained in cases related to code generation
19367 (rather than semantic checking) since otherwise we do not generate
19368 similar code for mutable private types depending if their
19369 discriminants are visible or not.
19370 (Check_Abstract_Overriding): Do not complain about failure to override
19371 the primitive operations used in dispatching selects since they will
19372 always be overriden at the freeze point of the type.
19373 (Access_Definition): Separate out handling for resetting the scope
19374 of an anonymous access function result type. Retrieve the scope
19375 of the associated function rather than using Current_Scope, which
19376 does not have a consistent value (depends on whether we're in the
19377 middle of analyzing formal parameters). Add ??? comment about
19378 finding a cleaner way to handle the special cases of scope setting.
19379 (Process_Incomplete_Dependents): A protected operation is never a
19380 dispatching operation (only its wrapper may be).
19381 (Build_Derived_Record_Type): In case of tagged private types that
19382 implement interfaces add derivation of predefined primitive
19384 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
19385 by two parameters that are used in case of derivation from abstract
19386 interface types: No_Predefined_Prims is used to avoid the derivation
19387 of predefined primitives from the interface, and Predefined
19388 Prims_Only is used to complete the derivation predefined primitives
19389 in case of private tagged types implementing interfaces.
19390 Fix typo in comments
19391 (Find_Interface_In_Descendant): Protect the frontend against
19392 wrong code with large circularity chains.
19393 (Is_Private_Overriding): Add support for entities overriding interface
19394 subprograms. The test failed because Entities associated with overriden
19395 interface subprograms are always marked as hidden (and used to build
19396 the secondary dispatch table); in this case the overriden entity is
19397 available through the field abstract_interface_alias (cf. override_
19398 dispatching_operation)
19399 (Access_Definition): Set the scope of the type to Current_Scope for the
19400 case of a function with an anonymous access result type.
19401 (Access_Subprogram_Declaration): Handle creation of the type entity for
19402 an access-to-function type with an anonymous access result.
19403 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
19404 in handling for N_Access_Function_Definition.
19405 (Analyze_Subtype_Declaration): Modify the text of error message.
19406 (Derived_Type_Declaration): Modify the text of error message.
19407 (Process_Subtype): Modify the text of error message plus cleanup
19408 of one redundant error message.
19409 (Analyze_Component_Declaration): Code cleanup.
19410 (Analyze_Object_Declaration): Code cleanup.
19411 (Analyze_Subtype_Declaration): Propagate the null-exclusion
19412 attribute in case of access types. Code cleanup.
19413 (Array_Type_Declaration): Code cleanup.
19414 (Process_Discriminants): Create the new null-excluding itype
19415 if required. Code cleanup.
19416 (Process_Subtype): Create the new null-excluding itype if
19417 required. Code cleanup.
19418 (Build_Derived_Record_Type): Code cleanup to avoid calling
19419 twice the subprogram derive_subprograms in case of private
19420 types that implement interfaces. In this particular case the
19421 subprogram Complete_Subprograms_Derivation already does the
19422 job associated with the second call.
19424 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
19425 conversion to the full view when generating an operation for a
19426 discriminant whose type may currently be private.
19428 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19429 Javier Miranda <miranda@adacore.com>
19431 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
19432 V (Obj.F), the rewriting does not involve the indexed component, but
19433 only the selected component itself.
19434 Do not apply the transformation if the analyzed node is an actual of a
19435 call to another subprogram.
19436 (Complete_Object_Operation): Retain the entity of the
19437 dispatching operation in the selector of the rewritten node. The
19438 entity will be used in the expansion of dispatching selects.
19439 (Analyze_One_Call): Improve location of the error message associated
19441 (Analyze_Selected_Component): No need to resolve prefix when it is a
19442 function call, resolution is done when parent node is resolved, as
19444 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
19445 when attempting to resolve a call transformed from its object notation.
19446 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
19447 of the argument list for each interpretation of the operation.
19448 (Try_Object_Operation): The designated type of an access parameter may
19449 be an incomplete type obtained through a limited_with clause, in which
19450 case the primitive operations of the type are retrieved from its full
19452 (Analyze_Call): If this is an indirect call, and the return type of the
19453 access_to_subprogram is incomplete, use its full view if available.
19455 2005-09-01 Javier Miranda <miranda@adacore.com>
19456 Gary Dismukes <dismukes@adacore.com>
19458 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
19459 access types the null-exclusion and access-to-constant attributes must
19461 (Analyze_Return_Statement): When the result type is an anonymous access
19462 type, apply a conversion of the return expression to the access type
19463 to ensure that appropriate accessibility checks are performed.
19464 (Analyze_Return_Type): For the case of an anonymous access result type,
19465 generate the Itype and set Is_Local_Anonymous_Access on the type.
19466 Add ??? placeholder for check to disallow returning a limited object
19467 in Ada 2005 unless it's an aggregate or a result of a function call.
19468 Change calls from Subtype_Mark to Result_Definition.
19469 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
19470 Result_Definition in call to Make_Function_Specification.
19471 (Build_Body_To_Inline): Change Set_Subtype_Mark to
19472 Set_Result_Definition.
19473 (Make_Inequality_Operator): Change formal Subtype_Mark to
19474 Result_Definition in call to Make_Function_Specification.
19475 (Process_Formals): Create the new null-excluding itype if required.
19476 (New_Overloaded_Entity): For an entity overriding an interface primitive
19477 check if the entity also covers other abstract subprograms in the same
19478 scope. This is required to handle the general case, that is, overriding
19479 other interface primitives and overriding abstract subprograms inherited
19480 from some abstract ancestor type.
19481 (New_Overloaded_Entity): For an overriding entity that comes from
19482 source, note the operation that it overrides.
19483 (Check_Conformance, Type_Conformant): Addition of one new formal
19484 to skip controlling formals in the analysis. This is used to
19485 handle overloading of abstract interfaces.
19486 (Base_Types_Match): Add missing case for types imported from
19487 limited-with clauses
19488 (New_Overloaded_Entity): Add barrier to protect the use of
19489 the "alias" attribute.
19491 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19493 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
19494 verify that the procedure and the entry are mode conformant.
19495 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
19496 as a different operator, which is often a cut-and-paste error.
19498 2005-09-01 Javier Miranda <miranda@adacore.com>
19499 Ed Schonberg <schonberg@adacore.com>
19501 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
19502 used in controlling parameters exclude null because it is necessary to
19503 read the tag to dispatch, and null has no tag.
19504 (Override_Dispatching_Operation): If the previous operation is inherited
19505 from an interface, it becomes hidden and does not participate in later
19508 2005-09-01 Javier Miranda <miranda@adacore.com>
19509 Ed Schonberg <schonberg@adacore.com>
19510 Gary Dismukes <dismukes@adacore.com>
19512 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
19513 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
19514 the expander will generate the corresponding run-time check to evaluate
19516 (Resolve_Call): Check for legal type of procedure name or prefix that
19517 appears as a trigger in a triggering alternative.
19518 (Valid_Conversion): If expression is ambiguous and the context involves
19519 an extension of System, remove System.Address interpretations.
19520 (Resolve_Qualified_Expression): Reject the case of a specific-type
19521 qualification applied to a class-wide argument. Enhance comment
19522 to explain checking of Original_Node.
19523 (Resolve_Type_Conversion): The location of the error message was not
19524 general enough to handle the general case and hence it has been removed.
19525 In addition, this patch improves the text of the message.
19526 (Resolve_Type_Conversion): Add missing support for access to interface
19528 (Resolve_Type_Conversion): If the target is a class-wide interface type,
19529 do not expand if the expression is the actual in a call, because proper

19541 (Interface_Present_In_Ancestor): In case of concurrent types we can't
19542 use the Corresponding_Record_Typ attribute to look for the interface

20350 longer protected objects. They have been replaced by lower-level
20351 suspension objects made up by a mutex and a condition variable (or
20352 their equivalent given a particular OS) plus some internal data to
20353 reflect the state of the suspension object.

20793 error message condition, null procedures are correctly detected now.
20794 (New_Overloaded_Entity): Bypass trivial overriding indicator check

20810 subprogram_specification that returns true if some non
20811 class-wide interface subprogram is found

20815 access to subprograms must be recursive.
20816 (Is_Unchecked_Conversion): Improve the test that recognizes
20817 instantiations of Unchecked_Conversion, and allows them in bodies that
20818 are to be inlined by the front-end. When the body comes from an

20841 object or component (that is, when Is_Local_Anonymous_Access is true).
20842 Prevent the special checks for conversions of access discriminants in
20843 the case where the discriminant belongs to a nonlimited type, since

20845 way as a normal component of an anonymous access type.
20846 (Resolve_Allocator): When an allocator's designated type is a class-wide
20847 type, check that the accessibility level of type given in the
20848 allocator's expression or subtype indication is not statically deeper
20849 than the level of the allocator's access type.

20865 pragma Restrictions (No_Obsolescent_Features).
20866 (Check_Direct_Boolean_Operator): If the boolean operation has been
20867 constant-folded, there is nothing to check.
20868 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
20869 check on possible violation of restriction No_Direct_Boolean_Operators
20870 until after expansion of operands, to prevent spurious errors when

20906 both bound checks, rather than a conjunction.
20907 (Insert_Valid_Check): If the expression is an actual that is an indexed
20908 component of a bit-packed array, force expansion of the packed element
20909 reference, because it is specifically inhibited elsewhere.

21827 (check dos line terminator).
21828 (Check_Line_Max_Length): New procedure, split off from the existing
21829 Check_Line_Terminator routine. Separating this out allows -gnatyf to
21830 be properly recognized.
21832 * styleg.adb: Add ??? comment for line terminator reference

21875 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
21876 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
21877 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
21878 analyzed if expansion is disabled (which could otherwise cause spurious
21879 error messages if expansion has been disabled due to previous
21880 (unrelated) errors).
21882 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
21883 is disabled, the entity denoted by the argument is the access type
21884 itself, not an underlying record type, so there is no need to go back
21885 to the Corresponding_Remote_Type.
21887 2005-03-29 Gary Dismukes <dismukes@adacore.com>
21888 Robert Dewar <dewar@adacore.com>
21890 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
21891 expand a call to an instance of
21892 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
21893 Constructor actual of the instance. A class-wide membership
21894 check is also generated, to ensure that the tag passed to the instance
21895 denotes a type in the class.
21896 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
21897 of Name_Generic_Dispatching_Constructor.
21899 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
21900 05 unit for AI-260-02).

21914 the case of renaming of stream attributes when the renaming denotes a
21915 generic formal subprogram association for an abstract formal subprogram.
21916 Check that the attribute is a primitive stream attribute (and not
21917 a class-wide stream attribute) and then rewrite the attribute name
21918 as the name of the appropriate compiler-generated stream primitive.
21920 2005-03-29 Robert Dewar <dewar@adacore.com>
21922 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

21927 2005-03-29 Ed Schonberg <schonberg@adacore.com>
21929 * freeze.adb (Freeze_Record_Type): If the type of the component is an
21930 itype whose parent is controlled and not yet frozen, do not create a
21931 freeze node for the itype if expansion is disabled.
21933 2005-03-29 Vincent Celier <celier@adacore.com>
21935 * make.adb (Gnatmake): Don't fail if the main project file is declared
21936 as having no Ada sources. Do not display message "no sources to
21937 compile" in quiet output.
21939 2005-03-29 Doug Rupp <rupp@adacore.com>
21941 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

21952 missing TYPE Improve the error message generated when compiling a
21953 limited interface in Ada83 or Ada95 mode.
21955 2005-03-29 Robert Dewar <dewar@adacore.com>
21957 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
21958 rather than proceed ahead using a junk attribute name.
21960 2005-03-29 Vincent Celier <celier@adacore.com>
21962 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
21964 * prj-part.adb (Parse_Single_Project): Set the location of a project
21965 on its defining identifier, rather than on the reserved word "project".
21967 * prj-proc.adb (Expression): Adapt to the fact that default of external
21968 references may be string expressions, not always literal strings.
21969 (Recursive_Process): Set Display_Name equal to Name
21970 when Location is No_Location, that is when there is no actual file.
21971 Get the Display_Name of the project from the source, when it is not a
21973 (Process): Use the Display_Name in error messages
21975 * prj-strt.adb (External_Reference): Allow default to be string
21976 expressions, not only literal strings.
21978 2005-03-29 Vincent Celier <celier@adacore.com>

21985 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
21986 forbid conversion of a local access-to-subprogram type to a remote one.
21988 * sem_util.adb (Wrong_Type): For a record type that is the expanded
21989 equivalent type for a remote access-to-subprogram type, go back to the
21990 original RAS entity when displaying an error message, so the casing is
21991 the original source casing.
21993 2005-03-29 Robert Dewar <dewar@adacore.com>
21995 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
21998 2005-03-29 Ed Schonberg <schonberg@adacore.com>
22000 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
22001 subtype if code is being pre-analyzed, to prevent un-expanded
22002 references to protected formals, among others.
22003 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
22004 interpretation that can be a call, include the result of the call as a
22005 possible interpretation of the dereference.
22007 * sem_ch5.adb (Process_Bounds): Determine type of range by
22008 pre-analyzing a copy of the original range, and then analyze the range
22009 with the expected type.
22011 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
22012 with an overloaded prefix where not all interpretations yield an
22013 access to subprogram, do not rewrite node as a call.
22014 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
22015 the node as a call once the context identifies the interpretation of
22016 the prefix whose call yields the context type.
22017 (Valid_Conversion): For the case of a conversion between
22018 local access-to-subprogram types, check subtype conformance using
22019 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
22020 detailed error message.
22022 2005-03-29 Ed Schonberg <schonberg@adacore.com>
22024 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
22025 indicator, indicate that the formal can never be null.
22026 (Process_Formals): If a formal has a non_null indicator, insert the
22027 resulting subtype immediately before the enclosing subprogram decl,
22028 and not at the beginning of the corresponding declarative part, to
22029 prevent access before elaboration (Ada2005).

22135 Adapt the code to traverse the entities in the
22136 scope of a record_type because in addition to its usage regarding

22138 to install the visible declarations of the enclosing scope of a
22139 record_type_with_private to establish the proper visibility before
22140 freezing the entity and related subprograms.

22150 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
22151 into a new Check_Attr subprogram, in order to provide a more
22152 explanatory error message (including the name of the missing attribute).
22153 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
22154 subprogram determines whether a default implementation exists for a
22155 given stream attribute.
22156 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
22157 Determine whether to generate a default implementation for each stream
22158 attribute separately, as this depends on the specific attribute.
22160 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
22161 limited extension where a stream attribute is missing for a limited
22162 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

22646 tables (rather than a single dispatch table).
22647 Similarly, upgrade all the references to Tag_Component by the
22648 new attribute First_Tag_Component.
22649 (Find_Inherited_TSS): Moved to exp_tss.
22650 Clean up test in Expand_N_Object_Declaration for cases
22651 where we need to do a separate assignment of the initial value.
22652 (Expand_N_Object_Declaration): If the expression in the
22653 declaration of a tagged type is an aggregate, no need to generate an
22654 additional tag assignment.
22655 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
22657 Bit packed array ops are only called if operands are known to be
22659 (Component_Equality): When returning an N_Raise_Program_Error statement,
22660 ensure that its Etype is set to Empty to avoid confusing GIGI (which
22661 expects that only expressions have a bona fide type).
22662 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
22663 determine the amount of data to be copied.
22665 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
22666 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
22667 INTERFACE_TYPE_DEFINITION ::=
22668 [limited | task | protected | synchronized] interface
22669 [AND interface_list]
22671 * par-ch3.adb (P_Type_Declaration): Modified to give support to
22673 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
22675 (P_Interface_Type_Definition): New subprogram that parses the new
22676 syntax rule of Ada 2005 interfaces
22677 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
22678 messages by the correct RENAMES (quotes removed).
22680 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
22681 attribute First_Tag_Component.
22683 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
22684 (Interface_List, Set_Interface_List): New subprograms.
22685 (Interface_Present, Set_Interface_Present): New subprograms.

22689 record type definition and
22690 derived type definition nodes.
22691 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
22692 (Task_Present, Set_Task_Present): New subprogram.
22693 (Task_Body_Procedure): Removed.
22694 (Set_Task_Body_Procedure): Removed.
22695 These subprogram have been removed because the attribute
22696 Task_Body_Procedure has been moved to the corresponding task type
22697 or task subtype entity to leave a field free to store the list
22698 of interfaces implemented by a task (for AI-345)
22699 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
22700 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
22701 expression flag Do_Range_Check
22702 (Exception_Junk): Change to Flag7 to accomodate above change
22703 (Box_Present, Default_Name, Specification, Set_Box_Present,
22704 Set_Default_Name, Set_Specification): Expand the expression
22705 "X in N_Formal_Subprogram_Declaration" into the corresponding
22706 two comparisons. Required to use the csinfo tool.
22708 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
22709 "with string" given.
22711 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
22714 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
22717 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
22718 attribute Task_Body_Procedure rather than the old semantic field that
22719 was available in the task_type_declaration node.
22721 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
22722 interface type definitions.
22723 (P_Formal_Derived_Type_Definition): Modified to handle the list of
22726 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
22727 task type declaration.
22728 (P_Protected): Modified to handle the list of interfaces in a
22729 protected type declaration.
22731 2005-03-15 Doug Rupp <rupp@adacore.com>
22732 Vincent Celier <celier@adacore.com>
22734 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
22735 (Gen_Output_File_C): Likewise.
22736 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
22738 2005-03-15 Thomas Quinot <quinot@adacore.com>
22740 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
22741 is an N_Raise_Constraint_Error node, create a new copy of it without
22742 going through a call to Duplicate_Subexpr.
22744 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
22745 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
22746 Nicolas Setton <setton@adacore.com>
22747 Ed Schonberg <schonberg@adacore.com>
22753 * decl.c (gnat_to_gnu_field): Reject aliased components with a
22754 representation clause that prescribes a size not equal to the rounded
22755 size of their types.
22756 (gnat_to_gnu_entity, case E_Component): Always look at
22757 Original_Record_Component if Present and not the entity.

22759 of tagged extension types by not making field for components that are
22761 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
22762 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
22763 expression to the type of the object when the object is constant.
22764 Reverse defer_debug_incomplete_list before traversing it, so that trees
22765 are processed in the order at which they were added to the list. This
22766 order is important when using the stabs debug format.
22767 If we are deferring the output of debug information, also defer this
22768 output for a function return type.
22769 When adding fields to a record, prevent emitting debug information
22770 for incomplete records, emit the information only when the record is
22772 (components_to_record): New parameter defer_debug.
22773 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
22774 (gnat_to_gnu_field_decl): New function.
22775 (substitution_list, annotate_rep): Call it.
22776 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
22777 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
22778 No longer update discriminants to not be a COMPONENT_REF.
22779 (copy_alias_set): Strip padding from input type; also handle
22780 unconstrained arrays properly.
22782 * gigi.h (write_record_type_debug_info): New function.
22783 Convert to use ANSI-style prototypes. Remove unused
22784 declarations for emit_stack_check, elab_all_gnat and
22785 set_second_error_entity.
22786 (gnat_to_gnu_field_decl): New decl.
22788 * utils.c (write_record_type_debug_info): New function.
22789 (finish_record_type): Delegate generation of debug information to

22791 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
22792 (update_pointer_to): Fix pasto.
22793 (convert) <UNION_TYPE>: Accept slight type variations when
22794 converting to an unchecked union type.
22796 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
22797 replace the N_Freeze_Entity with a null statement.
22799 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
22800 within a constrained subcomponent of an enclosing record, place the
22801 freeze nodes in the scope stack entry for the enclosing record.
22802 (Undelay_Type): New Subprogram.
22803 (Set_Small_Size): Pass T, the type to modify; all callers changed.
22804 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
22805 within records; allow them to have freeze nodes if their base types
22808 * exp_util.adb (Remove_Side_Effects): Properly test for
22809 Expansion_Delayed and handle case when it's inside an
22810 N_Qualified_Expression.
22812 * sem_ch3.adb (Derived_Type_Declaration): New predicate
22813 Comes_From_Generic, to recognize accurately that the parent type in a
22814 derived type declaration can be traced back to a formal type, because
22815 it is one or is derived from one, or because its completion is derived
22817 (Constrain_Component_Type): If component comes from source and has no
22818 explicit constraint, no need to constrain in in a subtype of the
22820 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
22821 Minor change to propagate Is_Ada_2005 flag
22823 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
22824 Expansion_Delayed is False.
22825 (assoc_to_constructor): Ignore fields that have a
22826 Corresponding_Discriminant.
22827 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
22828 function returns "by target", dereference the target pointer using the
22829 type of the actual return value.
22830 <all>: Be prepared for a null gnu_result.
22831 (processed_inline_subprograms): Check flag_really_no_inline
22832 instead of flag_no_inline.

22838 2005-03-15 Robert Dewar <dewar@adacore.com>
22839 Ed Schonberg <schonberg@adacore.com>
22840 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
22842 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
22843 Must_Be_Byte_Aligned for cases where we do not need to use a
22844 System.Pack_nn unit.
22846 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
22848 Needed now that we do some processing for IN parameters as well. This
22849 may well fix some unrelated errors.
22850 (Expand_Call): Handle case of unaligned objects (in particular those
22851 that come from packed arrays).
22852 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
22853 renamed entity is an inherited operation, re-expand the call using the
22854 original operation, which is the one to call.
22855 Detect attempt to inline parameterless recursive subprogram.
22856 (Represented_As_Scalar): Fix to work properly with private types
22857 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
22858 accurate estimate. Yields True in far fewer cases than before,
22859 improving the quality of code that depends on this test.
22861 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
22862 over both visible and private declarations to remove them from tree,
22863 and mark subprograms declared in package as eliminated, to prevent
22864 spurious use in subsequent compilation of generic units in the context.
22866 * exp_util.ads: Minor cleanup in variable names
22868 * sem_eval.ads, sem_eval.adb: Minor reformatting
22869 (Compile_Time_Known_Bounds): New function
22871 2005-03-15 Ed Schonberg <schonberg@adacore.com>
22873 * exp_ch7.adb (Convert_View): Use base types of underlying types when
22874 determining whether an unchecked conversion is needed for the argument
22875 of an initialization call.
22877 2005-03-15 Ed Schonberg <schonberg@adacore.com>
22879 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
22880 that appears in the instantiation rather than the internal subtype
22881 generated in the wrapper package, to avoid anomalies in gigi when the
22882 target is derived from a private type whose full view is an access type.
22884 2005-03-15 Robert Dewar <dewar@adacore.com>
22886 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
22888 Add documentation to replace the use of this flag
22889 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
22892 2005-03-15 Thomas Quinot <quinot@adacore.com>
22894 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
22895 here from exp_attr so it can be shared between exp_attr and exp_dist.
22896 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
22897 all TSS names, not a subset thereof, and the previous name introduced
22898 an unnecessarily confusion that a distinction might exist between
22899 "OK" TSS names and some "not OK" TSS names.
22901 2005-03-15 Doug Rupp <rupp@adacore.com>
22903 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
22906 2005-03-15 Pascal Obry <obry@adacore.com>
22907 Eric Botcazou <ebotcazou@adacore.com>
22911 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
22912 when IN_RTS. This is to work around a bootstrap path problem.
22914 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
22915 table and pass it to __gnat_install_SEH_handler().
22916 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
22918 * lang.opt: Fix specification of -fRTS=.
22920 2005-03-15 Doug Rupp <rupp@adacore.com>
22921 Bernard Banner <banner@adacore.com>
22922 Vincent Celier <celier@adacore.com>
22923 Arnaud Charlet <charlet@adacore.com>
22926 This change works fine when gnatlib is built from the gcc directory,
22927 but does not work when using the libada Makefile, since GCC_FOR_TARGET
22928 is not passed to ada/Makefile.in, so more work is needed by a
22929 Makefile/configure expert.
22931 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
22932 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
22933 Setup gnatlink switch -M for x86_64 linux, as it is already setup
22935 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
22936 Run ranlib on libgccprefix.a
22937 Define PREFIX_OBJS for Darwin, to build libgccprefix.
22938 (ADA_INCLUDE_SRCS): Split Ada packages.
22940 2005-03-15 Robert Dewar <dewar@adacore.com>
22942 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
22944 * impunit.adb: Add GNAT.UTF_32
22946 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
22948 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
22949 now uses GNAT.UTF_32).
22951 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
22952 capabilities for categorizing characters using Unicode categories
22954 2005-03-15 Ed Schonberg <schonberg@adacore.com>
22956 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
22957 instantiation that has been rewritten as a package body, retrieve spec
22958 to generate proper name for implicit_with_clause.
22959 (Install_Parents): Recognize a parent that is an instantiation but has
22960 been rewritten as a package declaration during analysis.
22962 2005-03-15 Javier Miranda <miranda@adacore.com>
22963 Ed Schonberg <schonberg@adacore.com>
22965 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
22966 parameter reported some error we immediately return. This improves the
22967 behaviour of the frontend in case of errors.
22968 (Install_Parent, Remove_Parent): Introduce new flag
22969 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
22970 ancestor of a generic child unit, when the child is being instantiated.
22971 (Inline_Instance_Body): If we are compiling the private
22972 part or the body of a child unit, restore the proper visibility of the
22973 parents after compiling the instance body.
22975 2005-03-15 Ed Schonberg <schonberg@adacore.com>
22976 Javier Miranda <miranda@adacore.com>
22979 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
22980 of a private type, in which case it is underlying_type that denotes
22981 the proper task. Also modified to use the new entity attribute
22982 that is directly available in the task type and task subtype entities
22983 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
22984 arrays when other dimensions than the first are constrained by
22985 discriminants of an enclosing record.
22986 (Insert_Explicit_Dereference): If the prefix is an indexed component or
22987 a combination of indexed and selected components, find ultimate entity
22988 and generate the appropriate reference for it, to suppress spurious
22990 (Note_Possible_Modification): If an entity name has no entity, return.
22991 (Is_Variable): A function call never denotes a variable.
22992 (Requires_Transient_Scope): For record types, recurse only on
22993 components, not on internal subtypes that may have been generated for
22994 constrained components.
22996 2005-03-15 Ed Schonberg <schonberg@adacore.com>
22998 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
22999 Eliminated as candidates for resolution. Both efficient, and avoids
23000 anomalies with operators declared in deleted code.
23001 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
23002 expansion is disabled (as when compiling a generic) to prevent spurious
23003 warnings on prefixes of selected components.
23005 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23007 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
23008 attached to a list before checking whether it appears in the private
23009 declarations of the current package.
23010 (Make_Inequality_Operator): Insert declaration in proper declarative
23011 list rather than just setting the Parent field, so that
23012 Is_Private_Declaration can handle it properly.
23014 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23016 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
23017 a renaming a body, check that the renamed subprogram in not intrinsic.
23018 (Find_Direct_Name): If several use_visible entities hide
23019 each other, and the context is a predefined file compiled through
23020 rtsfind, keep only the entity that comes from a predefined file.
23022 2005-03-15 Geert Bosch <bosch@adacore.com>
23024 * s-fatgen.adb (Valid): Extend special exceptions to account for long
23025 long float padding to also cover AMD64 and IA64.
23027 2005-03-15 Gary Dismukes <dismukes@adacore.com>
23029 * s-imgwch.adb: Add with and use of Interfaces.
23030 (Img_Wide_Character): Change type of Val to Unsigned_16.
23031 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
23033 2005-03-15 Matthew Gingell <gingell@adacore.com>
23035 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
23037 2005-03-15 Robert Dewar <dewar@adacore.com>
23039 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
23041 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
23043 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
23045 2005-03-15 Robert Dewar <dewar@adacore.com>

23069 procedures in the bug boxes for various GNAT builds.
23071 2005-03-15 Vincent Celier <celier@adacore.com>
23073 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

23078 Cyrille Comar <comar@adacore.com>
23079 Sergey Rybin <rybin@adacore.com>
23081 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
23082 too specific and long-winded to be appropriate for the GNAT User's
23084 Warn about use of GCC switches not documented in the GNAT User's Guide,
23085 as these may cause generated code to not conform to Ada semantics.
23086 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
23087 Add documentation for -gnat95 and -gnat05 switches
23088 Remove paragraph documenting obsolete way to refer to third party
23090 Add a few references to Ada_05 that were missing.
23091 Update documentation on -gnatZ/-gnatL.
23092 Document limitation when using -m64 under Solaris.
23093 Change the "Name Casing" subsection of the pretty-printer section
23094 according to the changes in the dictionary processing.
23096 * gnat_rm.texi: Document the Ada_05 pragma.
23097 Section on record representation clauses describes the new more
23098 relaxed rules about placement of large packed bit array components.
23099 Add documentation of GNAT.UTF_32
23101 2005-03-12 Daniel Berlin <dberlin@dberlin.org>

23110 2005-03-07 James A. Morrison <phython@gcc.gnu.org>
23111 Laurent Guerby <laurent@guerby.net>
23114 * system-linux-sparc.ads: New.

23364 value by a warning message.
23365 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted

23484 describing the new layout.
23485 (Dispatch_Table): The expander computes the actual array size, allocates

23505 dispatching, setting the controlling status of the formal parameters
23506 and result, and issuing an error if there is no controlling type for
23507 the formal subprogram.
23508 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
23509 which is an unclean use of that field, we set the new field
23510 Corresponding_Formal_Spec to make the formal subprogram available to

23523 subprogram only if inner one comes from source.
23524 (Analyze_Function_Call): If the call is given in object notation, the

23526 argument list. After analyzing the name, if the call has been rewritten
23527 and the result type is set, no further analysis is needed.
23528 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
23529 mark in function specification, in a context where the formals are
23530 visible and hide outer homographs.
23532 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
23533 as the tagged type for the cases of abstract formal subprograms and
23534 renamings of those. Clean up spec comments.
23535 (Check_Dispatching_Context): Add error message to indicate "abstract
23536 procedure", covering the case of a call to a formal abstract procedure
23537 that has statically tagged operands.
23538 (Check_Dispatching_Call): Check for the case of an actual given by
23539 a tag-indeterminate function call whose type is an ancestor of the
23540 containing call's associated tagged type. This situation can occur
23541 for inherited primitives with function defaults. In this case we
23542 use the tagged type's tag directly as the controlling argument for

23608 (__gnat_set_close_on_exec): New routine to support
23609 GNAT.OS_Lib.Set_Close_On_Exec.
23611 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
23612 the parent side as close-on-exec so that they are not inherited by the
23615 * g-os_lib.ads, g-os_lib.adb (Set_Close_On_Exec): New subprogram to
23616 set or clear the FD_CLOEXEC flag on a file descriptor.
23618 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
23619 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
23623 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
23624 on the field if Pragma Component_Alignment (Storage_Unit).
23625 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
23626 side-effects as if it were a constant; also make SAVE_EXPR to protect
23628 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
23630 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.

23644 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23646 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
23647 component of an array of arrays in an assignment context, and the
23648 aggregate has component associations that require sliding on
23649 assignment, force reanalysis of the aggregate to generate a temporary
23650 before the assignment.
23651 (Must_Slide): Make global to the package, for use in Gen_Assign.
23653 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23655 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
23656 unchecked union with no inferable discriminants, return a
23657 Raise_Program_Error node, rather than inserting it at the point the
23659 (Expand_Record_Equality, Component_Equality): Handle properly the case
23660 where some subcomponent is an unchecked union whose generated equality
23661 code raises program error.

23669 Arnaud Charlet <charlet@adacore.com>
23671 * init.c (__gnat_initialize): Add a new parameter eh which contains the
23672 address of the exception registration. The Win32 version of this
23673 routine calls __gnat_install_SEH_handler() to initialize the SEH
23674 (Structured Exception Handling) handler.
23675 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
23676 SEH (Structured Exception Handling) now.
23677 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
23678 (__gnat_initialize for ppc-vxworks): Adjust comments and the
23679 preprocessor condition protecting the call to the extra eh setup
23680 subprogram, which is only available for the ppc target.
23681 (__gnat_clear_exception_count): replaced reference to
23682 variable taskIdCurrent by call to taskIdSelf(), cleaner.
23684 * seh_init.c: New file.

23687 (GNATBIND_OBJS): Idem.
23689 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
23690 routine takes a new parameter (a pointer to the exception registration
23691 for the SEH (Structured Exception Handling) support.
23693 * raise.h: (__gnat_install_SEH_handler): New prototype.
23694 Update copyright notice.
23696 * s-tassta.adb (Task_Wrapper): Declare the exception registration
23697 record and initialize it by calling __gnat_install_SEH_handler.

23722 -shared-libgcc is now used by default on some systems (e.g. linux with
23724 Remove references to Makefile.prolog/generic, no longer used.
23726 2005-02-09 Vincent Celier <celier@adacore.com>
23728 * prj-makr.adb (Process_Directory): Put file name in canonical case
23729 before matching against the patterns.
23730 If gnatname has been invoked as <prefix>-gnatname
23731 then invoke the compiler as <prefix>-gcc, not just "gcc".
23733 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23735 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
23736 with expansion disabled. The actual subtype is needed among other
23737 places when the selected component appears in the context of a loop
23738 bound, and denotes a packed array.
23739 (Operator_Check): Always use the first subtype in the
23740 error message, to avoid the appearance of internal base types.
23741 (Transform_Object_Operation): Copy each actual in full
23742 to the parameter associations of the constructed call, rather than
23743 using the shallow copy mechanism of New_Copy_List. This ensures that
23744 the chaining of named associations is done properly.
23745 (Complete_Object_Operation): Rewrite node, rather than
23746 replacing it, so that we can trace back to the original selected
23749 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
23750 and calls that use object notation, if the called function is not
23751 declared in a withed unit, place the elaboration constraint on the
23752 unit in the context that makes the function accessible.
23753 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
23754 imposes an elaboration constraint between two packages.
23756 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23758 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
23759 views of a private type after handling its private dependents, to
23760 maintain proper stack discipline between entry and exit from the
23763 2005-02-09 Cyrille Comar <comar@adacore.com>

23783 * xr_tabls.ads: Add ??? comment for missing overall comment
23785 * xsinfo.adb: Make default file name be sinfo.h, since this is what
23786 we now use by default.
23788 * xsnames.adb: Adjust end of file test to look for five space followed
23789 by '#' instead of six spaces. The format of xsnames.adb was modified
23790 in the last update.
23792 * a-numeri.ads: Add reference to AI-388 for greek letter pi
23795 * clean.adb: Minor reformatting.
23797 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
23798 gnatname.adb: Minor reformatting

23803 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
23806 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
23808 2005-02-09 Sergey Rybin <rybin@adacore.com>
23810 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
23811 the difference between compact and incompact layout and add the record
23812 representation clause to the example illustrating different layouts.
23813 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
23814 component clauses").
23816 2005-02-09 Florian Villoing <villoing@adacore.com>
23818 * gnat_ugn.texi: Fix typos.
23819 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

23868 2005-02-09 Arnaud Charlet <charlet@adacore.com>
23870 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
23871 since this procedure is now too complex to be worth inlining.

24009 (Resolve_Access, case 'Access): Note that GNAT uses the context type to
24010 disambiguate overloaded prefixes, in accordance with AI-235. GNAT code
24011 predates, and partly motivates, the adoption of the AI.

24124 The current code actually does not check antyhing - this a placeholder
24125 for future refinements.
24126 (gnat_to_gnu_entity) <E_Subprogram_Call>: Add preliminary bits to handle

24170 variable Dynamic_Async.
24171 (Build_Subprogram_Receiving_Stubs): Make PCS-specific

24539 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
24540 with an implicit dereference as its prefix, use

24543 prefix is generated, if appropriate.
24545 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
24546 dereference is rewritten to an explicit one, generate a reference to
24547 the entity denoted by its prefix using the original prefix node, so

24549 access value, if appropriate.
24551 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
24552 emitting 'assigned but never read' warning on a variable on the basis

24566 an external name, to be handled by the back end.
24568 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
24569 subprogram which is Imported with convention Intrinsic if an
24570 External_Name argument is specified.
24571 (Process_Import_Or_Interface): Properly diagnose link name argument.
24572 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

24659 (Remove_Next): Same cleanup
24661 2004-12-07 Thomas Quinot <quinot@adacore.com>
24663 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
24664 used to record an implicit dereference as a read operation on its
24665 prefix when operating under -gnatc. Necessary to avoid spurious
24666 'variable assigned but never read' warnings in that mode.
24667 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
24668 is a non-overloaded implicit dereference, call the above subprogram to
24669 ensure proper recording of references.
24671 2004-12-07 Gary Dismukes <dismukes@adacore.com>
24673 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

24723 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
24724 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
24725 and -eit to -ept. Added qualifier
24726 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
24728 2004-11-27 Andreas Schwab <schwab@suse.de>

24734 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
24735 internal implementation unit GNAT.Sockets.Thin,
24736 as their usage for sockets is non-portable (using the read and write
24737 functions from the system runtime library is fine on UNIX but won't
24738 work under Windows).
24740 * mingw32.h: Update copyright notice.
24742 2004-11-25 Arnaud Charlet <charlet@adacore.com>

24787 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
24788 address of which may be used to represent "others" and "all others"

24791 (Setup_Exception): Do nothing in the GNAT SJLJ case.
24793 * gigi.h (others_decl, all_others_decl): New decls representing the
24794 new Others_Value and All_Others_Value objects.
24795 (struct attrib): Rename "arg" component as "args", since GCC expects a
24796 list of arguments in there.
24798 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
24799 corresponding objects exported by a-exexpr, instead of hardcoded dummy
24802 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
24803 others_decl and all_others_decl instead of hardcoded dummy addresses
24804 to represent "others" and "all others" choices, which is cleaner and
24805 more flexible with respect to the possible eh pointer encoding policies.
24807 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
24808 (process_attributes): Account for the naming change of the "args"
24809 attribute list entry component.

24812 cumulating attributes for different entities into a single list.
24813 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
24814 attributes for the current entity and propagate first subtype
24815 attributes to other subtypes.
24816 <E_Procedure>: Attribute arguments are attr->args and not
24817 attr->arg any more.
24818 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
24819 argument provided, as this is what GCC expects. Use NULL_TREE instead

24857 (First_RCI_Subprogram_Id): Document this constant.
24858 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
24860 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
24861 replaced with calls to Get_Library_Unit_Name_String. Previously there
24862 were several instances of the same code in different locations in the
24863 compiler; this checkin completes the replacement of all of these
24864 instances with calls to a common subprogram.
24865 Minor reformatting.
24867 * sem_dist.adb: Remove comment noting that RPC receiver generation
24868 should be disabled for RACWs that implement RASs.

24894 (Expand_Pragma_Psect_Object): New procedure
24895 These procedures contain the revised and cleaned up processing for
24896 these two pragmas. This processing was formerly in Sem_Prag, but
24897 is more appropriately moved here. The cleanup involves making sure
24898 that the pragmas are properly attached to the tree, and that no
24899 nodes are improperly shared.
24901 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
24902 pragmas to Exp_Prag, which is more appropriate.
24903 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
24904 check for duplicates Remove use of Is_Psected flag, no longer needed.
24905 Use new Make_String_Literal function with string.
24907 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
24908 that are functions return universal values, that have to be converted
24909 to the context type.
24910 Use new Make_String_Literal function with string.
24911 (Get_Stream_Convert_Pragma): New function, replaces the use of
24912 Get_Rep_Pragma, which had to be kludged to work in this case.
24914 * freeze.adb: Use new Has_Rep_Pragma function
24916 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
24917 function with string.

24944 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
24945 discriminant of a constrained subtype, analyze the copy of the
24946 corresponding constraint, because in some cases it may be only
24947 partially analyzed.
24948 Removes long-lived ??? comments.
24950 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
24951 handled controlled or secondary-stack expressions within the
24952 iteration_scheme of a loop.
24954 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
24955 bounds that may contain functions calls, to prevent memory leaks when
24956 the bound contains a call to a function that uses the secondary stack.
24957 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
24958 generate temporaries for loop bounds that might contain function calls
24959 that require secondary stack and/or finalization actions.
24961 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
24962 selected component and the selector is overloadable (not just a
24963 function) treat as function call, Analyze_Call will disambiguate if
24965 (Analyze_Selected_Component): Do not generate an actual subtype for the
24966 selected component if expansion is disabled. The actual subtype is only
24967 needed for constraint checks.

24969 not permit objects to be declared of a stream type, or of a
24970 composite type containing a stream.
24972 * restrict.ads: Remove the a-stream entry from Unit_Array, since
24973 No_Streams no longer prohibits with'ing this package.
24975 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
24976 discriminants, but the parent base has unknown discriminants, there is
24977 no discriminant constraint to inherit. Such a discrepancy can arise
24978 when the actual for a formal type with unknown discriminants is a
24979 similar private type whose full view has discriminants.
24980 (Analyze_Object_Declaration): If restriction No_Streams is set, then
24981 do not permit objects to be declared of a stream type, or of a
24982 composite type containing a stream.
24984 2004-11-18 Ed Schonberg <schonberg@adacore.com>
24986 * exp_dbug.ads: Update documentation to reflect simpler encoding for
24987 protected operations.
24989 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
24990 generated name, it complicates decoding in gdb and hinders debugging
24991 of protected operations.

24993 flag for the protected entry barrier function.
24994 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info

25034 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
25035 for Detect_Blocking which is redundant with the check done within the
25036 procedure Protected_Single_Entry_Call.
25037 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
25038 Detect_Blocking which is redundant with the check done within the
25039 procedure Protected_Single_Entry_Call.

25043 * makegpr.adb (Compile): Put the compiling switches (in package
25044 Compiler and on the command line) immediately after "-c", instead of
25045 at the end of the command line invocation of the compiler, when
25046 compiling a non-Ada file.
25047 (Build_Global_Archive): When there is no need to rebuild the archive,
25048 set Global_Archive_Exists, so that the archive is passed to the linker

25057 Remove paragraph about gnatelim debug options.
25059 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
25060 objects rather than forbidding dependencies on the package Ada.Streams.

25088 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
25089 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
25090 there is no use of GNAT.Sockets.Constants.
25091 Remove remaining pragma Import for C_Write
25092 Remove C_Read and C_Write from internal implementation unit
25093 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
25094 the read and write functions from the system runtime library is fine
25095 on UNIX but won't work under Windows).
25097 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
25098 (Check_Selector): Use C_Recv instead of C_Read.
25099 Selectors are the GNAT.Sockets abstraction to perform a select()
25100 call on a set of descriptors. To allow abortion of an ongoing
25101 select operation, some data is written to a dedicated socket that
25102 is always monitored.
25103 Under Windows, the write and read library functions cannot operate
25104 on sockets, so we need to use send and recv instead, which is portable
25105 across all supported platforms.
25107 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
25108 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
25109 (using the read and write functions from the system runtime library is
25110 fine on UNIX but won't work under Windows).
25112 2004-10-26 Nicolas Setton <setton@act-europe.fr>
25114 * mlib-tgt-darwin.adb: New file.
25116 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
25117 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
25118 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
25119 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
25122 * Makefile.in: Add support for building shared libraries under Darwin.
25123 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
25124 the low level EH init subprogram to be called from __gnat_initialize.
25126 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
25127 indicates which options to pass to the archive indexer.
25129 * mlib-utl.adb: Add support for calling ranlib with additional
25130 options. This is needed for instance under Mac OS X.
25131 (Ranlib_Options): New global variable, used to store the potential
25132 options to pass to ranlib.
25133 (Ar): Use Ranlib_Options when spawning ranlib.
25134 (Initialize): Set the value of ranlib option.
25136 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
25138 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
25139 instead of 8K, to reflect the real potential needs for stack-checking
25142 2004-10-26 Pascal Obry <obry@gnat.com>
25144 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
25146 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
25147 Windows only the initial thread stack size can be set so it is good to
25148 start we a low stack size.
25149 The OS will adjust the size as needed.
25151 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
25152 Nicolas Setton <setton@act-europe.fr>
25154 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
25155 "__unix__" instead of "unix".
25156 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
25157 sections were just mistakenly ignored. The former is
25158 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
25159 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
25160 of hpux. This prevents an unwanted definition of the symbol
25161 convert_addresses in adaint.o.
25163 2004-10-26 Gary Dismukes <dismukes@gnat.com>
25165 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
25166 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
25168 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25170 * a-filico.ads, a-filico.adb: fix incorrect header.
25172 2004-10-26 Javier Miranda <miranda@gnat.com>
25174 * a-ststio.ads: Fix typo in identifier
25176 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25178 * sem_ch4.adb: Minor reformatting.
25180 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25182 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
25183 enabled, check the result of unary and binary operations when the
25184 expression is the right-hand side of an assignment.
25186 2004-10-26 Vincent Celier <celier@gnat.com>
25188 * clean.adb (Delete): Do not output warnings when in quiet output and
25189 not in verbose mode.
25190 (Force_Deletions): New Boolean flag, defaulted to False
25191 (Delete): Only delete a file if it is writable, and when
25192 Force_Deletions is True.
25193 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
25194 (Usage): Line for new switch -f
25195 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
25198 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
25200 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
25201 JM type only if its size matches that of the wrapper. When a size is
25202 prescribed and the field is not aliased, remove the wrapper of a JM
25203 type only if the size is not greater than that of the packed array.
25204 (gnat_to_gnu_entity): Change the extension of packed array wrappers
25207 2004-10-26 Geert Bosch <bosch@gnat.com>
25209 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
25210 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
25211 (Pred): Implement in terms of Succ.
25213 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25215 * exp_aggr.adb (Safe_Component): An aggregate component that is an
25216 unchecked conversion is safe for in-place use if the expression of the
25217 conversion is safe.
25218 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
25219 be expandable in place even if the aggregate does not come from source.
25220 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
25221 designated object of an allocator in place, rather than building it
25222 first on the stack. The previous scheme forces a full copy of the array,
25223 and may be altogether unsusable if the size of the array is too large
25224 for stack allocation.
25226 2004-10-26 Robert Dewar <dewar@gnat.com>
25228 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
25229 compares if the component is atomic.
25231 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
25232 array assignment if the component type is atomic.
25234 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25235 Eric Botcazou <ebotcazou@act-europe.fr>
25237 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
25238 is aliased and is a by_reference type, do not pass by copy.
25239 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
25240 detect whether the call is in the right side of an assignment or
25241 the expression of an object declaration. Recurse on component
25242 association within aggregates.
25243 Call it in the condition that determines whether the temporary is
25244 necessary for correct stack-checking.
25246 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25248 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
25249 RACW_Type, used in the PolyORB version.
25250 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
25251 version and the GARLIC version.
25253 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
25254 Rename RCI_Info to RCI_Locator for better consistency between the
25255 GARLIC and PolyORB versions of the distributed systems annex.
25256 (DSA_Implementation_Name): This enumeration lists the possible
25257 implementations of the Partition Communication Subsystem for the
25258 Distributed Systems Annex (DSA). The three available implementations
25259 are the dummy stub implementation (No_DSA), and two versions based on
25260 two different distribution runtime libraries: GARLIC and PolyORB. Both
25261 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
25263 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
25266 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
25267 between the GARLIC and PolyORB versions of the distributed systems
25269 Remove RE_Unbounded_Reclaim_Pool since it is unused.
25271 2004-10-26 Gary Dismukes <dismukes@gnat.com>
25273 * gnat1drv.adb: Suppress calling the back end when
25274 Frontend_Layout_On_Target is true.
25276 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25278 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
25279 Set_Read_Only): New subprograms.
25280 These new routines allow the user to set or unset the Owner execute
25281 and Owner write permission flags on a file.
25283 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
25284 GNAT.OS_Lib.Set_Executable instead of rolling our own.
25286 2004-10-26 Matthew Gingell <gingell@gnat.com>
25288 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
25290 2004-10-26 Pascal Obry <obry@gnat.com>
25292 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
25293 memory before the faulting page we properly test the process read
25294 access for this address using appropriate Win32 routine.
25295 (HPUX sections): guard with "__hpux__" instead of "hpux".
25297 2004-10-26 Robert Dewar <dewar@gnat.com>
25299 * lib-xref.adb (Generate_Reference): Don't complain about reference to
25300 entry parameter if pragma Unreferenced set, since we do not properly
25301 handle the case of multiple parameters.
25303 2004-10-26 Vincent Celier <celier@gnat.com>
25305 * prj-env.adb: (Contains_ALI_Files): New Boolean function
25306 (Ada_Objects_Path.Add): For a library project, add to the object path
25307 the library directory only if there is no object directory or if the
25308 library directory contains ALI files.
25309 (Set_Ada_Paths.Add.Recursive_Add): Ditto
25311 2004-10-26 Vincent Celier <celier@gnat.com>
25313 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
25314 extension of library projects.
25316 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
25317 path defaults to ".:<prefix>/lib/gnat".
25318 (Parse): For an extending all project, allow direct import of a project
25319 that is virtually extended.
25321 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
25322 the specified name is directly imported, return its ID. Otherwise, if
25323 an extension of this project is imported, return the ID of the
25326 2004-10-26 Robert Dewar <dewar@gnat.com>
25328 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
25329 (Sub3): New procedure, used by Scaled_Divide
25330 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
25331 correct more than one instance of failure to propagate carries
25333 (Double_Divide): Handle overflow case of largest negative number
25334 divided by minus one.
25336 * s-arit64.ads (Double_Divide): Document that overflow can occur in
25337 the case of a quotient value out of range.
25340 2004-10-26 Robert Dewar <dewar@gnat.com>
25342 * s-bitops.adb (Bit_Eq): Remove redundant check.
25344 * s-bitops.ads: Minor comment updates
25345 Change some occurrences of Address to System.Address
25347 * s-carsi8.ads: Fix minor cut-and-paste error in comments
25349 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25351 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
25352 accessibility check to prefix that is a protected operation.
25354 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25356 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
25357 empty, post message on stub.
25359 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25360 Javier Miranda <miranda@gnat.com>
25362 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
25363 current instance appears within a unit that is directly in the context
25365 Used to determine whether the body of the instance should be analyzed
25366 immediately after its spec, to make its subprogram bodies available
25367 for front-end inlining.
25368 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
25369 constraint is not allowed on the component type (AARM 12.5.3(3))
25371 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25373 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
25374 'Storage_Pool): enhance, document & limit detection of non-sharable
25377 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
25379 * s-pooglo.ads: Add more documentation now that this pool is properly
25382 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25384 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
25385 or protected type with discriminants, do not constrain the
25386 corresponding record type if the subtype declaration has no
25387 discriminant constraints. This can be the case in source code, or in
25388 the subtype declaration created to rename an actual type within an
25391 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25393 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
25394 different kind of stub (possibly wrong name for file), do not check
25396 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
25397 includes call to some function that returns an unconstrained type, do
25400 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25402 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
25403 appear in the code for the main unit. Dependencies among units in the
25404 context of the main unit are established when those other units are
25405 compiled. Otherwise spurious elaboration constraints can generate
25406 incorrect elaboration circularities.
25408 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25409 Ed Schonberg <schonberg@gnat.com>
25411 * sem_util.adb (Is_Aliased_View): Defend against the case where this
25412 subprogram is called with a parameter that is not an object name. This
25413 situation arises for some cases of illegal code, which is diagnosed
25414 later, and in this case it is wrong to call Is_Aliased, as that might
25415 cause a compiler crash.
25416 (Explain_Limited_Type): Refine previous fix to include
25417 inherited components of derived types, to provide complete information.
25419 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
25420 is the prival for a protected object.
25421 It is necessary to mark this entity as a variable, in addition to
25422 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
25423 modified to avoid checking the Aliased flag on entities that are not
25424 objects. (Checking that flag for non-objects is erroneous and could
25425 lead to a compiler crash).
25427 2004-10-26 Robert Dewar <dewar@gnat.com>
25429 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
25430 X_Frac = 0.5, then we know that the number X must be positive.
25431 (Succ): Remove the same redundant test, and also fix the primary test
25432 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
25434 (Decompose): Add fuller comments to spec
25436 2004-10-26 Pascal Obry <obry@gnat.com>
25438 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
25439 validity (process must have read access). Set to 0 in all other cases.
25440 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
25441 violation on Win32.
25442 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
25443 segmentation violation.
25445 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
25447 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
25448 whose type is a constructed subtype of an aliased object with an
25449 unconstrained nominal subtype, convert the actual to the constructed
25450 subtype before taking its address.
25452 2004-10-26 Vincent Celier <celier@gnat.com>
25454 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
25455 (Is_Path_Name_Case_Sensitive): New function
25457 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
25458 (Base_Name, Simple_Name, Current_Directory, Compose,
25459 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
25462 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25463 Vasiliy Fofanov <fofanov@act-europe.fr>
25464 Vincent Celier <celier@gnat.com>
25466 * gnat_ugn.texi: Generalize "finding memory problems" section into a
25467 "memory management issues" section and document some of the useful
25468 memory pools provided as part of the GNAT library.
25469 Remove "virtual" from declaration of A::method2 in
25470 the simple example of Ada/C++ mixed system.
25471 Library Projects may be virtually extended: their virtual extensions
25472 are not Library Projects.
25473 Added section on extending project hierarchies.
25475 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
25477 * adaint.c (__gnat_get_libraries_from_registry): Cast value
25479 (__gnat_portable_spawn): Remove const.
25481 * mingw32.h (MAXPATHLEN): Check for previous definition.
25483 2004-10-17 Matthias Klose <doko@debian.org>
25485 * gnatvsn.ads: Set gnat library version to 4.0.
25487 2004-10-05 Vincent Celier <celier@gnat.com>
25489 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
25491 2004-10-04 Laurent Guerby <laurent@guerby.net>
25494 * Makefile.in: Define and use RANLIB_FLAGS.
25496 2004-10-04 Pascal Obry <obry@gnat.com>
25498 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
25499 other x86 platforms).
25501 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
25503 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
25504 in general and triggers stack alignment adjustment for thread entry
25505 points on targets where this is necessary.
25507 2004-10-04 Bernard Banner <banner@gnat.com>
25510 * Makefile.in: Add section for powerpc linux
25511 Add variant i-vxwork-x86.ads
25513 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
25515 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
25517 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
25518 table registration calls when need be. Ensures no reference to the crt
25519 ctors symbol are issued in the SJLJ case, which avoids possible
25520 undefined symbol errors in the case of modules to be statically linked
25523 2004-10-04 Javier Miranda <miranda@gnat.com>
25525 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
25526 in-line the code corresponding to subprogram Analyze_Actuals. In
25527 addition, analyze the actuals only in case of subprogram call.
25529 2004-10-04 Ed Falis <falis@gnat.com>
25531 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
25533 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
25535 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
25536 in the documentation.
25538 2004-10-04 Robert Dewar <dewar@gnat.com>
25540 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
25542 (Analyze_Block_Statement): Add circuitry to detect following dead code
25543 (Check_Unreachable_Code): Handle case of block exit
25545 2004-10-04 Robert Dewar <dewar@gnat.com>
25547 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
25548 (XMatchD): Avoid warning for Logic_Error call
25550 2004-10-04 Robert Dewar <dewar@gnat.com>
25552 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
25553 consider expressions buried within a procedure actual to be an actual.
25554 This caused some blowups with uses of packed slices within a procedure
25557 2004-10-04 Robert Dewar <dewar@gnat.com>
25559 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
25560 longer need to be initialized to zero.
25561 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
25562 initialized to zero.
25564 * checks.adb (Expr_Known_Valid): Packed arrays are now always
25565 considered valid, even if the representation is modular. That's correct
25566 now that we no longer initialize packed modular arrays to zero.
25568 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
25569 suffixes. These are now documented as the only cases in which the
25570 debugger ignores outer records.
25571 Previously, the spec allowed arbitrary suffixes for this purpose.
25572 Change name of LJM to JM for packed array pad records
25573 Create separate section on packed array handling, and add a whole new
25574 set of comments to this section describing the situation with packed
25575 modular types and justification requirements depending on endianness.
25577 2004-10-04 Robert Dewar <dewar@gnat.com>
25579 * a-except.adb: Add a comment for last change
25581 * einfo.ads: Minor spelling correction in comment
25583 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
25585 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
25588 * sem_util.ads: Minor comment update
25590 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25592 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
25593 Inline_Always when in Configurable_Run_Time mode.
25595 * sem_prag.adb (Process_Convention): If entity is an inherited
25596 subprogram, apply convention to parent subprogram if in same scope.
25597 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
25598 when in Configurable_Run_Time mode.
25600 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25602 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
25603 class_wide type after component list has been inherited.
25605 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25607 * sem_ch12.adb (Check_Generic_Actuals): New predicate
25608 Denotes_Previous_Actual, to handle properly the case of a private
25609 actual that is also the component type of a subsequent array actual.
25610 The visibility status of the first actual is not affected when the
25611 second is installed.
25612 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
25613 make fully recursive the treatment of formals of packages declared
25615 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
25616 the above on exit from an instantiation.
25617 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
25618 current instantiation which is now complete.
25619 (Analyze_Package_Instantiation): No instantiated body is needed if the
25620 main unit is generic. Efficient, and avoid anomalies when a instance
25621 appears in a package accessed through rtsfind.
25623 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25625 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
25626 do not generate a declaration for a temporary if the call is part of a
25627 library-level instantiation.
25629 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25631 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
25632 searching for a limited component to flag.
25634 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
25635 expansion of Input, to account for the fact that the implicit call
25636 generated by the attribute reference must freeze the user-defined
25637 stream subprogram. This is only relevant to 'Input, because it can
25638 appear in an object declaration, prior to the body of the subprogram.
25640 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
25641 expansion can proceed and further errors uncovered.
25642 (Minor clean up): Fix cases of using | instead of \ for continuation
25645 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
25647 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
25649 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
25650 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
25651 Use gcc_assert and gcc_unreachable.
25653 * decl.c (gnat_to_gnu_entity, case object): Check and process a
25654 specified alignment before validating size.
25655 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
25656 stripped-down declaration for the type of the inner field when making
25659 * utils.c (finish_record_type): Do not compute the size in units
25660 incrementally. Instead compute it once for the rep clause case.
25661 Use gcc_assert and gcc_unreachable.
25663 2004-10-04 Vincent Celier <celier@gnat.com>
25665 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
25667 (Is_Valid_Path_Name): Take '/' as a directory separator.
25669 2004-10-04 Vincent Celier <celier@gnat.com>
25671 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
25672 (Extended_Project) only if Extended_Project is defined, to avoid
25674 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
25676 (Parse_Single_Project): Ditto.
25678 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
25679 Add_To_Project_Path for virtual projects.
25681 2004-10-04 Vincent Celier <celier@gnat.com>
25683 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

25686 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
25687 parameter Options_2.
25689 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
25690 Build_Dynamic_Library with an empty Options_2.
25692 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
25695 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
25696 directory separator, if any.
25697 (Gprmake): Do not allow mains on the command line for library projects.
25698 Do not attempt to link when the project is a library project.
25699 (Library_Opts): New table to store Library_Options.
25700 (Build_Library): If Library_Options is specified, pass these options
25701 when building a shared library.
25703 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
25705 * s-tposen.adb (Service_Entry): The object must be always unlocked at
25706 the end of this procedure now that the unlock operation was inserted
25709 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
25711 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
25712 corresponding to the Preallocated_Stacks flags in System.
25713 (Get_Target_Parameters): Including the processing for
25714 Preallocated_Stacks.

25724 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
25725 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
25726 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
25727 used to signal whether the compiler creates the required stacks and
25728 descriptors for the different tasks (when True) or it is done by the
25729 underlying operating system at run time (when False).
25730 It is initially set to False in all targets.
25732 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
25733 if it is supported by the target.
25734 (Make_Task_Create_Call): Pass the stack address if it has been
25735 previously created. Otherwise pass a Null_Address.
25737 * snames.adb: Add _stack.
25739 * snames.ads: Add Name_uStack. Required to allow the expander to
25740 statically allocated task stacks.
25742 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
25743 Stack_Address argument.
25744 Check that its value is equal to Null_Address because this target does
25745 not support the static stack allocation.
25747 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
25749 * usage.adb: Change "pragma inline" to "pragma Inline" in information
25752 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
25754 * exp_dist.adb: Split declaration of asynchronous flag out of
25755 Add_RACW_Read_Attribute.
25756 Minor reformatting for better alignment with PolyORB version.
25757 Store the entity for the asynchronous flag of an RACW, rather than the
25758 expression, in the asynchronous flags table. This will allow this flag
25759 to be used in other subprograms beside Add_RACW_Read_Attribute.
25761 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
25763 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

25767 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
25768 sockets constant MSG_NOSIGNAL (Linux-specific).
25769 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
25770 all Send operations.
25771 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
25772 from trigerring SIGPIPE.
25773 Rename components to avoid clash with Ada 2005 possible reserved
25775 (Check_Selector): When the select system call returns with an error
25776 condition, propagate Socket_Error to the caller.
25778 2004-10-01 Jan Hubicka <jh@suse.cz>
25780 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
25782 2004-09-23 Robert Dewar <dewar@gnat.com>
25785 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
25786 instead do this at freeze time (we won't do it if there is an address
25788 Change "pragma inline" to "pragma Inline" in information and error
25790 Minor reformatting.
25792 * freeze.adb (Check_Address_Clause): Remove previous change, not the
25793 right way of doing things after all.
25794 (Freeze_Entity): For object, set Is_Public for imported entities
25795 unless there is an address clause present.
25797 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
25799 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
25800 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
25801 ensures proper handling of types with rep clauses, which might have
25802 their TYPE_SIZE set already.
25804 2004-09-21 Robert Dewar <dewar@gnat.com>
25806 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
25807 packed array types in both little- and big-endian cases. This change
25808 ensures that we no longer count on the unused bits being initialized
25809 for such types (and in particular ensures that equality testing will
25810 only read the relevant bits).
25811 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
25812 These changes mean that we no longer need to initialize small packed
25814 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
25815 optimization to an LJM field as to its parent field.
25817 * ada-tree.h, trans.c, utils.c, utils2.c:
25818 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
25820 2004-09-20 Jan Hubicka <jh@suse.cz>
25822 * utils.c (gnat_finalize): Remove.
25823 (end_subprog_body): Directly call cgraph_finalize_function;
25824 do not lower the nested functions.
25826 2004-09-20 Robert Dewar <dewar@gnat.com>
25829 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
25830 if an address clause is present, since that means that the Import
25833 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
25835 * 5tsystem.ads: Removed, no longer used.
25837 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
25838 Zack Weinberg <zack@codesourcery.com>
25840 * ada-tree.def: Use tree_code_class enumeration constants
25841 instead of code letters.
25842 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
25843 Update for new tree-class enumeration constants.

25858 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
25859 an existing directory.
25860 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
25861 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
25862 Convert the result to File_Size.
25864 * prj.ads: (Project_Error): New exception
25866 * prj-attr.adb: Except in procedure Initialize, Fail comes from
25867 Prj.Com, not from Osint.
25868 (Attrs, Package_Attributes): Tables moved to private part of spec
25869 (Add_Attribute, Add_Unknown_Package): Moved to new child package
25871 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
25872 Prj.Project_Error after call to Fail.
25873 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
25874 Fail. Check that package name is not already in use.
25876 * prj-attr.ads: Comment updates to indicate that all subprograms may be
25877 used by tools, not only by the project manager, and to indicate that
25878 exception Prj.Prj_Error may be raised in case of problem.
25879 (Add_Unknown_Package, Add_Attribute): Moved to new child package
25881 (Attrs, Package_Attributes): Table instantiations moved from the body to
25882 the private part to be accessible from Prj.Attr.PM body.
25884 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
25885 from new package Prj.Attr.PM.
25886 (Parse_Attribute_Declaration): Call Add_Attribute from new package
25889 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
25891 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
25892 instead of Elaboration_Checks).
25894 * a-calend.adb: Minor reformatting
25896 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

25922 * utils.c (create_subprog_type): New operand RETURNS_BY_TARGET_PTR.
25923 (create_var_decl): Refine when TREE_STATIC is set.
25924 Convert to use buildN.

25937 pragmas recognized by GNAT.
25939 * gnat_rm.texi: Document pragma Detect_Blocking.
25941 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
25942 raise Program_Error if called from a protected operation.
25944 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
25945 the protected action nesting level.
25946 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
25947 protected action nesting level.
25948 (Unlock): When pragma Detect_Blocking is active decrease the protected
25949 action nesting level.
25951 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
25952 Protected_Action_Nesting.
25954 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
25955 Common_ATCB record. It contains the dynamic level of protected action
25956 nesting for each task. It is needed for checking whether potentially
25957 blocking operations are called from protected operations.
25958 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
25959 Detect_Blocking is active or not in the partition.
25961 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
25962 raise Program_Error if called from a protected operation.

25971 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
25972 raise Program_Error if called from a protected operation, and increase
25973 the protected action nesting level.
25974 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
25975 Program_Error if called from a protected operation, and increase the
25976 protected action nesting level.

25978 protected action nesting level.
25980 * s-tposen.adb (Lock_Entry): When pragma Detect_Blocking is active,
25981 raise Program_Error if called from a protected operation, and increase
25982 the protected action nesting level.
25983 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
25984 Program_Error if called from a protected operation, and increase the
25985 protected action nesting level.

25990 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
25991 protected action nesting level.
25993 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
25994 insertion of the statement raising Program_Error. The run time
25995 contains the required machinery for handling that.
25997 * sem_util.ads: Change comment associated to procedure
25998 Check_Potentially_Blocking_Operation.
25999 This procedure does not insert a call for raising the exception because
26000 that is currently done by the run time.
26002 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
26004 * init.c: Add the global variable __gl_detect_blocking that indicates
26005 whether pragma Detect_Blocking is active (1) or not (0). Needed for
26006 making the pragma available at run time.
26007 (__gnat_set_globals): Pass and update the detect_blocking parameter.
26009 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
26010 pragma Detect_Blocking is active.
26012 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
26014 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
26015 DB is found in the ali file. Any unit compiled with pragma
26016 Detect_Blocking active forces its effect in the whole partition.
26018 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
26019 Detect_Blocking is active and delay is called from a protected
26022 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
26023 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
26024 Detect_Blocking is active (0 otherwise).
26025 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
26026 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
26029 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
26031 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
26032 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
26035 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
26036 (Register_Receiving_Stub): Add Subp_Info formal parameter.
26037 Update API in placeholder implemetation of s-parint to reflect changes
26038 in distribution runtime library.
26040 * sem_ch3.adb (Expand_Derived_Record): Rename to
26041 Expand_Record_Extension.
26043 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
26044 primitive operations of potentially distributed object types that have
26045 non-controlling anonymous access formals.
26047 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
26049 New implementation of expansion for remote access-to-subprogram types,
26050 based on the RACW infrastructure.
26051 This version of sem_dist is compatible with PolyORB/DSA as well as
26054 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
26055 Asynchrronous that applies to a remote access-to-subprogram type, mark
26056 the underlying RACW type as asynchronous.
26058 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
26059 __gnat_using_gnu_linker to 1.
26061 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
26062 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
26063 GNAT.Perfect_Hash_Generators, and remove the empty
26064 GNAT.Perfect_Hash package.
26066 * atree.adb: Minor reformatting
26068 * exp_ch3.adb (Expand_Derived_Record): Rename to
26069 Expand_Record_Extension.
26070 (Build_Record_Init_Proc.Build_Assignment): The default expression in
26071 a component declaration must remain attached at that point in the
26072 tree so New_Copy_Tree copies it if the enclosing record type is derived.
26073 It is therefore necessary to take a copy of the expression when building
26074 the corresponding assignment statement in the init proc.
26075 As a side effect, in the case of a derived record type, we now see the
26076 original expression, without any rewriting that could have occurred
26077 during expansion of the ancestor type's init proc, and we do not need
26078 to go back to Original_Node.
26080 * exp_ch3.ads (Expand_Derived_Record): Rename to
26081 Expand_Record_Extension.
26083 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
26084 Returns the RACW type used to implement a remote access-to-subprogram
26086 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):

26281 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
26282 target names rewrite to fix regressions with recent version of

26336 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
26337 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared

26361 for a global aliased object with a variable size and an unconstrained
26362 nominal subtype, pretend there is no initializer if the one we have is
26363 incomplete, and avoid referencing an inexistant component in there. The
26364 part we have will be rebuilt anyway and the reference may confuse

26387 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
26388 unit, this is an attempt to inline a construct that is not available in
26389 the current restricted mode, so abort rather than trying to continue.
26391 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
26392 discriminants that rename those of the parent, recover names of
26393 original discriminants for the constraint on the full view of the

26396 subtype is an itype.
26398 * gnat_rm.texi: Added section on implementation of discriminated

26424 returning C.int, to avoid using a derived boolean type.
26426 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

26455 ignore overflows on low and high bounds of an index to also account for
26456 differences in signedness between sizetype and gnu_index_subtype.
26457 These are as legitimate as the ones caused by a lower TYPE_PRECISION

29084 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
29085 overriding, use the operation of the parent unconditionally.
29087 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
29088 operation when either operand is a literal, to avoid further
29091 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

30373 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
30374 complete assignment subtree which is now unnecessary, as the expansion
30375 of inlined call has been improved to preserve a consistent assignment
30376 tree. Note_Possible_Modification must be called only
30377 after checks have been applied, or else unnecessary checks will
30380 * sem_util.adb (Note_Possible_Modification): Reorganise the handling

30384 recorded as modifying the pointer);

30638 * osint.adb (Executable_Prefix): Set Exec_Name to the current
30639 executable name when not initialized. Otherwise, use its current value.
30641 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
30642 initialize it to another executable name than the current one. This
30643 allows to configure paths for an executable name (gnatmake) different
30644 from the current one (gnatdist).
30646 2004-03-29 Ed Schonberg <schonberg@gnat.com>
30648 * exp_ch6.adb (Expand_Call): A call to a function declared in the
30649 current unit cannot be inlined if it appears in the body of a withed
30650 unit, to avoid order of elaboration problems in gigi.
30652 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
30653 information for protected (wrapper) operation as well, to simplify gdb
30656 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
30657 protected body, indicate that the entity for the generated spec comes
30658 from source, to ensure that references are properly generated for it.

30693 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
30695 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
30696 attribute reference does not denote a subtype, it can be any
30697 expression that has a classwide type, potentially after an implicit
30698 dereference. In particular, the prefix can be a view conversion for
30699 a classwide type (for which Is_Object_Reference holds), but it can
30700 also be a value conversion for an access-to-classwide type. In the
30701 latter case, there is an implicit dereference, and the original node
30702 for the prefix does not verify Is_Object_Reference.
30704 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
30705 conversion of a discriminant-dependent component of a mutable object
30708 2004-03-25 Ed Schonberg <schonberg@gnat.com>
30710 * freeze.adb (Freeze_Entity): When an inherited subprogram is
30711 inherited, has convention C, and has unconstrained array parameters,
30712 place the corresponding warning on the derived type declaration rather
30713 than the original subprogram.

30729 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
30730 value expressions to ensure that calls within a component definition
30731 will be checked (since those are evaluated during the record type's

30783 declaration for a child subprogram body that acts as a spec, indicate
30784 that the entity in the declaration needs debugging information.
30786 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
30787 full view if the subtype is created for a constrained record component;
30788 gigi has enough information to construct the record, and there is no
30789 place in the tree for the declaration.
30791 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
30792 serial number for the dummy body that is built for analysis, to avoid

30830 Minor reformatting.
30832 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
30834 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
30835 as regular exception objects and not as mere integers representing the
30836 condition code. The latter approach required some dynamics to mask off
30837 severity bits, which did not fit well into the GCC table based model.
30838 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
30839 exception data objects. We don't it and it would conflict with the other
30840 external symbol we have to generate for such exceptions.
30842 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
30843 the special code for VMS exceptions, since these are now represented
30844 as regular exceptions objects.
30846 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30848 * decl.c (debug_no_type_hash): Remove.

30886 * init.c [VxWorks]: Do not fix the stack size for the environment task.
30887 When needed (stack checking) the stack size is retrieved
30888 from the VxWorks kernel.
30890 * Makefile.in: Flag -nostdinc is required when building the run time
30891 for avoiding looking for files in the base compiler.
30892 Add the VxWorks specific version of the package body for
30893 System.Stack_checking.Operations (5zstchop.adb).
30895 * Make-lang.in: Add the object file for
30896 System.Stack_Checking.Operations.

30920 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
30921 the procedures Add_To_Path_File.
30922 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
30923 making sure that each directory is present only once and, for object
30924 dirs, when a directory already present is added, the duplicate is
30925 removed and the directory is always put as the last in the table.
30926 Write the path files at the end of these accumulations.

30929 Files_Htable for all sources.

30949 * sem_warn.adb (Check_References): For a warning on a selected
30950 component that does not come from source, locate an uninitialized
30951 component of the record type to produce a more precise error message.

30977 * a-ngcoty.adb (Modulus): In alternate formula for large real or
30978 imaginary parts, use Double precision throughout.
30980 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
30981 we want to be able to compile run-time with -gnata for testing, but
30982 this may also be instantiated in user code that is compiled with -gnata.

31001 occurrence matches some handler choice specification. Extracted out of
31002 get_action_description_for, and expanded to take care of the VMS
31004 (get_action_description_for): Use is_handled_by instead of an explicit
31005 complex condition to decide if the current choice at hand catches the
31006 propagated occurrence.
31008 * raise.h (Exception_Code): New type for C.
31010 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
31011 System.Standard_Library.Exception_Code, to allow references from the

31019 routine which will now be able to call the appropriate exception data
31022 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
31023 component of Standard_Exception_Type to be the closest possible to
31024 Exception_Code in System.Standard_Library, that we cannot get at this
31025 point. Expand a ??? comment to notify that this type node should
31026 probably be rewritten later on.
31028 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
31029 registration call to include a pointer to the exception object in the
31032 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

31052 (Scan_Make_Arg): Add the executable suffix only if the argument
31053 following -o, in canonical case, does not end with the executable
31054 suffix. When in verbose mode and executable file name does not end
31055 with executable suffix, output the executable name, in canonical case.
31057 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
31058 to avoid warnings when instantiating Ada.Task_Attributes.

31077 corresponding dispatch entry is properly initialized.
31078 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
31079 when looking for user-defined equality operation.

31082 boolean when locating primitive equality of tagged component.
31084 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

31135 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
31136 Insert_Dereference_Action when rewriting an implicit dereference into
31137 an explicit one, this will be taken care of during expansion of the
31138 explicit dereference.
31139 (Expand_N_Slice): Same. Always do the rewriting, even for the case
31140 of non-packed slices, since the dereference action generated by
31141 expansion of the explicit dereference is needed in any case.
31142 (Expand_N_Selected_Component): When rewriting an implicit dereference,
31143 analyze and resolve the rewritten explicit dereference so it is seen
31145 (Insert_Dereference_Action): This procedure is now called only for the
31146 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
31147 dereferences that do not come from source (including explicit
31148 dereferences resulting from rewriting implicit ones), but do not
31149 recursively insert a check for the dereference nodes contained within
31151 (Insert_Dereference_Action): Clarify and correct comment.

31987 No_Requeue_Statements.
31989 * s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)

32022 * utils.c (create_field_decl): Augment the head comment about bitfield
32023 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
32024 here, because the former is not accurate enough at this point.
32025 Let finish_record_type decide instead.
32026 Don't make a bitfield if the field is to be addressable.
32027 Always set a size for the field if the record is packed, to ensure the
32028 checks for bitfield creation are triggered.
32029 (finish_record_type): During last pass over the fields, clear
32030 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
32031 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
32032 from DECL_BIT_FIELD.

32489 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
32490 N_String_Literal node always references an E_String_Literal_Subtype
32491 entity. This may not be true in the future.
32492 (Possible_Bit_Aligned_Component): Move processing of
32493 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
32495 * exp_ch6.adb (Expand_Thread_Body): Pick up
32496 Default_Secondary_Stack_Size as variable so that we get value modified
32497 by possible -Dnnn binder parameter.
32499 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
32500 (Type_May_Have_Bit_Aligned_Components): New function.

32540 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
32541 ineffective elaborate all pragmas on non-visible packages (this
32542 happened when a renamed subprogram was called). Now the elaborate all
32543 always goes on the package containing the renaming rather than the one
32544 containing the renamed subprogram.
32546 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
32547 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

32572 * make.adb (Gnatmake): Special process for files to compile/check when
32573 -B is specified. Fail when there are only foreign mains in attribute
32574 Main of the project file and -B is not specified. Do not skip bind/link
32575 steps when -B is specified.

32620 based on the new naming scheme.
32622 * gnatlink.adb (Process_Binder_File): Properly detect the new naming

32764 to __gnat_map_signal, imported from init.c to support
32765 signal -> exception mappings that depend on the vxWorks version.
32768 Created and exported __gnat_map_signal to support signal -> exception
32769 mapping that is dependent on the VxWorks version.

32800 2003-12-11 Ed Schonberg <schonberg@gnat.com>
32802 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
32803 bounds of a loop, create a separate block in order to generate proper
32804 cleanup actions to prevent memory leaks.
32806 * sem_res.adb (Resolve_Call): After a call to
32807 Establish_Transient_Scope, the call may be rewritten and relocated, in
32808 which case no further processing is needed.

32826 2003-12-08 Robert Dewar <dewar@gnat.com>
32828 * 7sintman.adb: Minor reformatting
32830 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
32831 standard linker options to get standard libraries linked. We now plan
32832 to provide dummy versions of these libraries to match the appropriate
32833 configurable run-time (e.g. if a library is not needed at all, provide
32834 a dummy empty library).
32836 * targparm.ads: Configurable_Run_Time mode no longer affects linker
32837 options (-L parameters and standard libraries). What we plan to do is
32838 to provide dummy libraries where the libraries are not required.
32840 * gnatbind.adb: Minor comment improvement
32842 2003-12-08 Javier Miranda <miranda@gnat.com>
32844 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
32845 aggregate in the parent. Otherwise constants with limited aggregates

32847 It is required to call the corresponding IP subprogram in case of
32848 default initialized components.
32849 (Gen_Assign): In case of default-initialized component, generate a
32850 call to the IP subprogram associated with the component.
32851 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
32852 of aggregate with default initialized components.
32853 (Has_Default_Init_Comps): Improve implementation to recursively check
32854 all the present expressions.
32856 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
32857 to indicate that the initialization call corresponds to a
32858 default-initialized component of an aggregate.
32859 In case of default initialized aggregate with tasks this parameter is
32860 used to generate a null string (this is just a workaround that must be
32861 improved later). In case of discriminants, this parameter is used to
32862 generate a selected component node that gives access to the discriminant
32865 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
32866 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
32867 allocated aggregates with default-initialized components.
32869 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
32870 the box notation is used in positional aggregates.

32889 Store_Comments is True.
32890 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
32891 comments are associated with these nodes. Store the node IDs in the
32893 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the

32898 for comment storage (Next_End, End_Of_Line, Previous_Line,
32901 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
32902 defaulted to False.

32912 Process nodes N_Comment.
32914 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
32915 without comments and there are some comments, set the flag
32916 Unkept_Comments to True.
32917 (Scan): If there are comments, set the flag Unkept_Comments to True and
32918 clear the comments.
32919 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
32920 (Next_End_Nodes: New table
32921 (Comment_Zones_Of): New function

32947 (Scan): Store position of start of comment. If comments are tokens, set
32948 Comment_Id and set Token to Tok_Comment when scanning a comment.
32949 (Set_Comment_As_Token): New procedure
32951 * sinput-p.adb: Update Copyright notice
32952 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

32957 * sem_aggr.adb: Add dependence on Exp_Tss package
32958 Correct typo in comment
32959 (Resolve_Aggregate): In case of array aggregates set the estimated
32960 type of the aggregate before calling resolve. This is needed to know
32961 the name of the corresponding IP in case of limited array aggregates.
32962 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
32963 in case of default initialized array components.
32965 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

32974 until bounds are analyzed, to diagnose premature use of type.
32976 * sem_util.adb (Wrong_Type): Improve error message when the type of
32977 the expression is used prematurely.

32985 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
32986 they are automatically generated by Make-lang.in and cause nothing but
32987 maintenance troubles.
32989 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
32991 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

33005 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
33006 to ensure that the kernel fills in the interrupted context structure
33007 before calling a signal handler, which is necessary to be able to
33008 unwind past it. Update the copyright notice.
33010 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
33012 * a-elchha.ads: New file.
33014 * a-elchha.adb: New default last chance handler. Contents taken from
33015 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
33017 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
33018 is moved to a-elchha.adb to provide a target-independent default last

33092 2003-12-03 Jose Ruiz <ruiz@act-europe.fr>
33095 When defining LIBGNAT_TARGET_PAIRS for bare board targets, remove the
33096 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
33097 included in HIE_NONE_TARGET_PAIRS.
33099 2003-12-03 Ed Schonberg <schonberg@gnat.com>
33102 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
33103 is legal in an instance, because legality is cheched in the template.
33106 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
33107 appplied to an unchecked conversion of a formal parameter.

36673 * gnat-style.texi (header): Add @dircategory, @direntry.
36674 (title page): Remove date.
36675 (general) Add @./@: where approriate, and two spaces after the
36676 full stop at the end of a sentence. Use @samp markup when
36677 referring concrete lexical entities (keywords, attribute names
36678 etc.), and @syntax for ARM grammar elements. Use @r for English

36734 * raise.c (__gnat_eh_personality): Exception handling personality
36735 routine for Ada. Still in rough state, inspired from the C++ version

36738 inspired from the C++ library.
36740 * raise.c (eh_personality): Add comments. Part of work for the GCC 3

36755 Add 2001 to copyright date
36757 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
36758 need to force universal inlining for these cases.
36760 2001-12-19 Arnaud Charlet <charlet@gnat.com>
36762 * s-taprob.adb: Minor clean ups so that this unit can be used in
36765 * exp_ch7.adb: Allow use of secondary stack in HI mode.
36766 Disallow it when pragma Restrictions (No_Secondary_Stack) is specified.

36788 discriminant check if the selected component is a component of
36789 the argument of an initialization procedure.
36791 * trans.c (tree_transform, case of arithmetic operators): If result
36792 type is private, the gnu_type is the base type of the full view,
36793 given that the full view itself may be a subtype.
36795 2001-12-17 Robert Dewar <dewar@gnat.com>
36797 * sem_res.adb: Minor reformatting
36799 * trans.c (tree_transform, case N_Real_Literal): Add missing third

37063 2001-12-17 Laurent Pautet <pautet@gnat.com>
37066 Fix comment of Shutdown_Socket and Close_Socket. These functions
37067 should not fail silently because if they are called twice, this
37068 probably means that there is a race condition in the user program.
37069 Anyway, this behaviour is consistent with the rest of this unit.
37070 When an error occurs, an exception is raised with the error message
37071 as exception message.

38403 (CRC_Match): new function.
38404 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
38405 instead of the previous simple checksum algorithm.
38406 (Time_Stamp_Mismatch): use CRC_Match for comparison.
38407 (Set_Source_Table): idem.
38410 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
38411 instead of simple checksum.
38412 (CRC_Match): new function.
38413 (CRC_Error): new constant.
38415 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
38416 a CRC now and not a simple checksum. A CRC uses lower-case hex
38417 letters, fixes ambiguity in parsing.
38419 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
38420 is what this variable will store.
38422 * bcheck.adb: Change reference to chechsum in comments by CRC.
38423 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
38424 rename All_Checksum_Match to All_CRC_Match. Change due to API
38425 renaming since now GNAT does not use a simple checksum but a
38426 CRC using GNAT.CRC32.
38428 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
38429 now and not anymore a simple checksum.
38431 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
38434 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
38437 (Restore_Scan_State): rename Checksum to CRC.
38438 (Save_Scan_State): idem.
38442 (Checksum): rename to CRC.
38443 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
38445 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
38446 GNAT.CRC32). Update copyright notice.
38448 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
38449 GNAT.CRC32). Update copyright notice.
38452 (Accumulate_Checksum): removed.
38453 (Update): new procedure. Add a wide-character into the CRC.
38456 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
38457 (Load_File): fix initialization of S (change Source_Checksum to
38460 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
38461 Source_CRC in S initialization.
38463 * sinput.adb (Source_Checksum): renamed to Source_CRC.
38465 * sinput.ads (Source_Checksum): renamed to Source_CRC.
38466 Update comments for the CRC.
38468 * types.adb (Hex): Use lowercase for the letter part.
38470 * types.ads (Get_Hex_String): Returns the hexadecimal representation
38471 for a word. This is currently used only for CRC. In previous version,
38472 the checksum was using a representation with all letter being
38473 upper-case. With the new implementation (using CRC) we do not remove
38474 the 32th bit of the CRC, so we can have an upper-case starting letter
38475 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
38476 It is ambigous since the CRC was optional and could be followed by
38477 options like EB, EE. So now this routines uses lower-case letter for
38478 the hexadecimal representation. Strange enough only lower case letters
38479 where checked in Scan_ALI (even if this was not a possible case).
38481 * gnatvsn.ads (Library_Version): changed to 3.15a.
38483 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
38486 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
38489 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
38490 Add 2001 to copyright notice
38491 (Accumulate_Checksum): Modify to use System.CRC32.
38493 * ali-util.ads: Redo changes of previous revision to continue to use
38494 the word Checksum. Add 2001 to copyright notice.
38496 * ali.adb: Undo some of previous changes, not needed.
38497 Keep the change for lower case letters in the checksum.
38499 * ali.ads: Undo previous change not needed.
38501 * bcheck.adb: Undo most of previous change, not needed.
38502 But do use Checksums_Match for checksum comparison.
38504 * gnatls.adb: Undo most of previous change, not needed.
38505 But do use Checksums_Match for comparing checksums.
38507 * lib-load.adb: Undo previous change, not needed.
38509 * lib-writ.adb: Undo previous change, not needed.
38511 * lib-writ.ads: Document that checksums use lower case,
38512 not upper case letters.
38514 * scans.adb: Undo previous change, not needed
38516 * scans.ads: Undo previous change, not needed.
38518 * scn-nlit.adb: Undo previous changes, not needed.
38520 * scn-slit.adb: Undo previous change, not needed. Fix header format.
