1504 Add support for parsing multiple array index types info, or
1505 multiple inherited interfaces info. This information cannot be stored
1506 in Xref_Entity_Record, which only supports a single instance of Tref_*,

1525 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
1526 that handles use of 'Access and 'Unchecked_Access applied to

1572 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info

1618 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
1619 association for an access component, add an association with null as
1620 the expression. Remove testing for array subtypes and the setting in
1621 that case of Ctyp to the array component type, which prevented proper
1622 inclusion of an association for null-initialized arrays. Collapse
1623 condition that tests for array subtypes into just a test of
1624 Is_Partially_Initialized_Type (which already covers arrays anyway).
1626 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

1641 * sem_ch4.adb: Minor code and comment reformatting.
1642 (Analyze_Allocator): When the designated type of an unconstrained
1643 allocator is a record with unknown discriminants or an array with
1644 unknown range bounds, emit a detailed error message depending on the
1645 compilation mode and whether the designated type is limited.

1776 * trans.c (number_files): New global variable.
1777 (gigi): Rename and change type of number_units parameter, change
1778 type of file_info_ptr parameter.
1779 If mapped location support is enabled, create the isomorphic mapping
1780 between source files and line maps.
1781 (Sloc_to_locus): If mapped location support is enabled, translate
1782 source location into mapped location.
1783 (annotate_with_node): Rename into set_expr_location_from_node.

1809 * a-calend-vms.adb, a-calend.adb:
1810 Add a section on leap seconds control along with two entities used to
1811 enable and disable leap seconds support. The array Leap_Second_Times is
1812 now constant and contains hard time values pre-generated. Remove
1813 all elaboration code used to populate the table of leap seconds.
1816 Add entity Leap_Seconds_Support to the list of global run-time variables
1817 along with a comment on its usage and values.
1818 (Gen_Adainit_Ada): Add code to generate the declaration and import of
1819 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
1820 or one (enabled) depending on the presence of binder switch "-y".
1821 (Gen_Adainit_C): Add code to generate the declaration of external int
1822 __gl_leap_seconds_support. Set is value to zero (disabled) or one

1833 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
1835 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
1837 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time

1873 2007-09-26 Javier Miranda <miranda@adacore.com>
1874 Eric Botcazou <ebotcazou@adacore.com>
1877 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
1878 indirection added to the HT_Link component of the TSD. This is required
1879 to statically allocate the TSD.
1882 Minor reordering of the declarations in the private part. Required to
1883 add a level of indirection to the contents of the TSD component HT_Link.
1884 This is required to statically allocate the TSD.
1886 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
1887 Is_Statically_Allocated set from constant objects.
1888 Do not make exported constants created by the compiler volatile.
1889 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
1892 * trans.c (Identifier_to_gnu): For constants, unshare initializers
1893 before returning them.
1895 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
1896 public part of the package.
1897 (Make_DT): Move HT_Link component out of the TSD record. For this
1898 purpose Make_DT now declares a separate object that stores the
1899 HT_Link value, and initializes the TSD component with the address
1900 of this new object. The addition of this level of indirection is
1901 required to statically allocate the TSD because the TSD cannot
1902 have variable components.
1903 (Expand_Interface_Conversion): Improve the expanded code.
1904 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
1906 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
1907 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
1908 if we are building static dispatch tables then we must not generate
1909 extra code to register the primitive because the dispatch table will
1910 be built at the end of the library package; otherwise we notify that
1911 we cannot build the static dispatch table.
1913 2007-09-26 Robert Dewar <dewar@adacore.com>
1915 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

1930 for thunks associated with interface types.
1932 * einfo.ads: Improve documentatation of Is_Internal
1933 (Is_Thunk): New attribute applicable to subprograms. True for thunks
1934 associated with interface types.
1935 Extensive comment fixes regarding flags that appear in all entities. The
1936 documentation is now consistent for all such flags (there were a number
1937 of errors in the documentation in this regard).
1939 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
1941 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
1942 of these procedures are passed a function call that already has
1943 build-in-place actuals (testing new flag
1944 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
1945 the case where processing continues.
1946 (Expand_Call): If the call is generated from a thunk body then we
1947 propagate the extra actuals associated with the accessibility
1948 level of the access type actuals.
1950 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
1951 of each extra formal of a protected operation to reference the
1952 corresponding extra formal of the subprogram denoted by the
1953 operation's Protected_Body_Subprogram.
1955 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
1956 N_Function_Call nodes.
1958 2007-09-26 Robert Dewar <dewar@adacore.com>
1960 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
1962 * debug.adb: Add d.s flag.
1964 2007-09-26 Gary Dismukes <dismukes@adacore.com>
1966 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
1967 debug variable so that it won't be initialized when pragma
1968 Initialize_Scalars is in effect.
1970 2007-09-26 Gary Dismukes <dismukes@adacore.com>
1972 * freeze.adb (Freeze_Entity): Remove check for preelaborable
1973 initialization of a full view. This is moved to
1974 Analyze_Package_Specification.
1976 * sem_ch7.adb (Analyze_Package_Specification): Add check for
1977 preelaborable initialization of a full view in entity loop.
1978 (Uninstall_Declarations): If entity is a use-visible compilation unit,
1979 its child units are use-visible only if they are visible child units.
1981 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
1982 whether an expression can be used within a type declaration that
1983 requires preelaborable init.
1984 (Check_Components): Replace inline code that does partial checking for
1985 preelaborable default expressions with call to
1986 Is_Preelaborable_Expression.
1987 (Has_Preelaborable_Initialization): In the case of a generic actual
1988 subtype, (that is, Is_Generic_Actual is True), return the result of
1989 applying Has_Preelaborable_Initialization to the generic actual's base
1992 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
1994 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
1995 call to Jan_1_Day _Of_Week to optimize its performance.
1996 (Is_Leap): Move the routine to the scope of Week_In_Year.
1997 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
1998 weekday on which January 1 falls of Year - 1 and Year + 1. This function
1999 avoids calling Time_Of and Split, thus making it more efficent.
2000 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
2002 * g-calend.ads (Week_In_Year): Change comment to reflect new
2005 2007-09-26 Emmanuel Briot <briot@adacore.com>
2007 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
2008 Command_Line): New types
2009 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
2010 support for defining how switches can be grouped on a command line (as
2011 is the case for -gnatw... for GNAT), and how simple switches can be
2012 used as aliases for more complex switches (-gnatwa is same as
2014 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
2015 (Start, Current_*): New subprograms
2016 Added support for parsing an array of strings in addition to the real
2018 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
2019 be moved from the body to the private part of the spec.
2020 (*): All subprograms now have an extra parameter with default value to
2021 specify which parser should be used. For backward compatibility, it
2022 defaults to parsing the command line of the application. They were also
2023 modified to properly handle cases where each of the argument does not
2024 start at index 1 (which is always true for Ada.Command_Line, but not
2025 when processing any Argument_List).
2026 (Free): New subprogram
2027 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
2028 Argument): New subprograms
2029 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
2030 special characters like ':', '=',... are now handled in a single place,
2031 which makes the code more extensible eventually.
2032 (Getopt, Full_Switch): When the switch was returned as part of the
2033 special character '*', make sure it is prepended by the switch character
2034 ('-' in general), so that the application knows whether "foo" or "-foo"
2035 was specified on the command line.
2037 2007-09-26 Florian Villoing <villoing@adacore.com>
2039 * g-dirope.adb (Remove_Dir): In case we are removing directories
2040 recursively, make sure that if an exception is raised during the
2041 processing, the current working directory is reset to its initial
2042 value before propagating the exception.
2044 2007-09-26 Vincent Celier <celier@adacore.com>
2046 * gnatbind.adb: If there are several ALI files specified and there is
2047 a main program to bind, the first ALI is expected to contain the main
2048 subprogram and the names of the binder generated files will be derived
2049 from the first ALI file name.
2050 (Gnatbind): Fix insertion character in invocation of Error_Msg
2052 2007-09-26 Vincent Celier <celier@adacore.com>
2054 * gnatcmd.adb (Check_Files): Do not include sources that have been
2055 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
2057 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2059 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
2060 information about each of its index types, following the type
2061 reference for its component type.
2063 2007-09-26 Vincent Celier <celier@adacore.com>
2065 * make.adb: (Kill): New procedure (__gnat_kill imported)
2066 (Running_Compile, Outstanding_Compiles): Global variables that
2067 were previously local to procedure Compile_Sources.
2068 (Sigint_Intercepted): Send signal SIGINT to all outstanding
2069 compilation processes.
2071 (Gnatmake): If project files are used, create the mapping of all the
2072 sources, so that the correct paths will be found.
2074 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
2076 2007-09-26 Vincent Celier <celier@adacore.com>
2078 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
2080 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
2081 Replace components Compiler_Min_Options and Binder_Min_Options with
2082 Compiler_Required_Switches and Binder_Required_Switches in record
2084 Remove components Default_Language and Config in Project_Tree_Data,
2087 * prj-attr.adb: New attributes Required_Switches (<language>) in
2088 packages Compiler and Binder.
2090 * prj-nmsc.adb: Major rewrite of the processing of configuration
2091 attributes for gprbuild. No impact on GNAT tools.
2093 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
2094 process configuration attributes: this is done in Prj.Nmsc.Check.
2095 (Recursive_Process): Make a full copy of packages inherited from project
2096 being extended, instead of a shallow copy.
2097 (Process_Project_Tree_Phase_1): New procedure
2098 (Process_Project_Tree_Phase_1): New procedure
2099 (Process): Implementation now uses the two new procedures

2433 potentially be called.
2434 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
2435 body for 'Output when the type is abstract (only the creation of the
2436 body for 'Input is excluded when the type is abstract).

2438 statement, so that False will be returned for TTS_Stream_Input if the
2439 associated tagged type is an abstract extension. Add comments for

2442 variable, insert init proc call only after the shared variable
2443 procedures have been processed, because the IP call needs to undergo
2444 shared passive variable reference expansion, which requires these
2445 procedures to be available (and elaborated).

2461 to remove other spurious ambiguities on arithmetic operations involving
2462 literals and addresses, on systems where Address is a visible integer
2463 type, when the operator is called in functional notation.
2464 (Try_Primitive_Operation): Within an instance, a call in prefixed form
2465 is legal when the types match, even if the operation is currently

2613 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
2614 library-level package renaming, pass the declaration associated with

2619 occurring in the list of entities to qualify, and do not attempt to
2620 traverse an entity list in that case. Variables associated with
2621 ` library-level package renamings can now occur in the table.

2647 avoid very deep recursion in the front end, which was causing stack
2650 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
2651 string, and the right operand is a string literal (the case of "" &

2653 value of the right operand directly.
2655 * stringt.adb (Store_String_Chars): Optimize by growing the
2656 String_Chars table all at once, rather than appending characters one by
2658 (Write_String_Table_Entry): If the string to be printed is very long,
2659 just print the first few characters, followed by the length. Otherwise,
2660 doing "pn(n)" in the debugger can take an extremely long time.
2662 * sem_prag.adb (Process_Interface_Name): Replace loop doing

2682 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
2683 flag, for effiency. It is called when analyzing arithmetic operators
2684 and also for actuals in calls that are universal_integers. The flag is
2685 set for the predefined type address, and for any type or subtype
2688 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
2689 Universal_Integer, when the formal is a descendent of address and the

2760 renaming declarations.
2762 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.

2770 (Debug_Renaming_Declaration): Replace creation of an enumeration type
2771 and literal with creation of a variable of type
2772 Standard_Debug_Renaming_Type whose name encodes both the renamed object
2773 and the entity of the renaming declaration.

2782 Ed Schonberg <schonberg@adacore.com>
2783 Javier Miranda <miranda@adacore.com>
2785 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
2786 ancestor part given by an aggregate to test for an unchecked conversion,
2787 since this can occur in some cases when the ancestor part is a function
2788 call, and we don't want to fall into the recursive call to this
2789 procedure in that case.
2791 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
2792 stream attributes on limited types to account for user-specified
2793 attributes as well as whether Input (resp. Output) becomes available
2794 due to Read (resp. Write) being available for the type. Change Boolean
2795 variable to the more accurate name
2796 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
2797 double-"not" predicate at beginning of return statement to more
2798 understandable form.
2800 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
2801 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
2802 in a block statement and use that as the first statement of the
2803 expanded return rather than incorrectly using the handled sequence as
2804 the first statement.
2806 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
2807 operation, generate an explicit freeze node for it rather than
2808 generating extra formals, to ensure that gigi has the proper order of
2809 elaboration for anonymous subtypes in the signature of the subprograms.
2810 (Build_In_Place_Formal): Move assertion to beginning of loop.
2811 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
2812 applied to a function call (occurs for some cases of 'Input).

2814 applied to a function call (occurs for some cases of 'Input).
2816 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
2817 2005, generate an extended return statement enclosing the result object
2820 * freeze.adb (Freeze_Record_Type): Extend the current management of
2821 components that are access type with an allocator as default value: add
2822 missing support to the use of qualified expressions of the
2823 allocator (which also cause freezing of the designated type!)
2824 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
2825 dispatching operation, since extra formals may be needed by calls to
2826 build-in-place functions (such as stream 'Input).
2828 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
2829 formals for 'Constrained and accessibility level in the case of a
2830 predefined dispatching operation.
2832 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
2833 point, no need to find the parent node.
2835 2007-08-16 Javier Miranda <miranda@adacore.com>
2837 * exp_attr.adb (Attribute_Priority): Add missing support for entries
2840 2007-08-16 Javier Miranda <miranda@adacore.com>
2842 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
2843 is not really required and can introduce regression with the debugger.
2844 The original problem is fixed with the patch written for checks.adb.
2846 2007-08-16 Thomas Quinot <quinot@adacore.com>
2848 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

2856 Including_Non_Switch set to False.
2858 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
2859 parameter Including_Non_Switch, defaulted to True. When
2860 Including_Non_Switch is False, options that are not switches and

2877 (Install_Limited_Withed_Unit): Do not install the limited view of
2878 package P if P is reachable through an ancestor chain from package C
2879 and C also has a with clause for P in its body.
2880 (Has_Limited_With_Clause): New routine.
2881 (Has_With_Clause): New routine.
2883 2007-08-16 Ed Schonberg <schonberg@adacore.com>
2885 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
2886 generic for an enclosing instance is a global reference, even though
2887 its scope is the enclosing instance.

2890 Javier Miranda <miranda@adacore.com>

2913 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
2914 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
2915 the statement which is being resolved comes from a predefined library
2916 unit, all non-predefined library interpretations are skipped.
2917 (Resolve_Op_Concat): If string concatenation was folded in the parser,
2918 but the "&" is user defined, give an error, because the folding would
2921 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
2922 the parser has folded a long sequence of concatenations of string
2925 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
2926 and "JMP_BUF" variables as artificial.
2927 (N_String_Literal): Do not use alloca for very long string literals. Use

2981 needed for access to concurrent record types generated by the expander.
2982 (Generate_Range_Check): When generating a temporary to capture the
2983 value of a conversion that requires a range check, set the type of the
2984 temporary before rewriting the node, so that the type is always
2985 properly placed for back-end use.
2986 (Apply_Float_Conversion_Check): Handle case where the conversion is
2988 (Get_Discriminal): Code reformatting. Climb the scope stack looking

3012 access parameter, do not apply an accessibility check when the
3013 operand's original node was an attribute other than 'Access. We now
3014 create access conversions for the expansion of 'Unchecked_Access and
3015 'Unrestricted_Access in certain cases and clearly accessibility should
3016 not be checked for those.
3018 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
3019 includes a type conversion of a packed component that has been expanded,
3020 recover the original expression for the object, and use this expression
3021 in the post-call assignment statement, so that the assignment is made
3022 to the object and not to a back-end temporary.
3023 (Freeze_Subprogram): In case of primitives of tagged types not defined
3024 at the library level force generation of code to register the primitive
3025 in the dispatch table. In addition some code reorganization has been
3026 done to leave the implementation clear.
3027 (Expand_Call): When expanding an inherited implicit conversion,
3028 preserve the type of the inherited function after the intrinsic
3029 operation has been expanded.
3031 * exp_ch2.ads, exp_ch2.adb
3032 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
3033 of an entry formal appearing in an assignment statement does not assign
3035 (Expand_Current_Value): Instead of calling a routine to determine
3036 whether the prefix of an attribute reference should be optimized or
3037 not, prevent the optimization of such prefixes all together.
3039 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
3040 component whose prefix is known to be of an access type is an implicit
3041 dereference and does not assign to the prefix.
3043 2007-08-14 Ed Schonberg <schonberg@adacore.com>
3044 Robert Dewar <dewar@adacore.com>
3046 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
3047 itype is visited, make an entry into table to link associated node and
3049 Add comments and correct harmless error in Build_NCT_Hash_Tables
3050 (Array_Aggr_Subtype): Associate each itype created for an index type to
3051 the corresponding range construct, and not to the aggregate itself. to
3052 maintain a one-to-one correspondence between itype and its associated
3053 node, to prevent errors when complex expression is copied.
3054 Fix mishandling of multiple levels of parens
3056 * sem_aggr.adb: Create a limited view of an incomplete type, to make
3057 treatment of limited views uniform for all visible declarations in a
3058 limited_withed package.
3059 (New_Copy_Tree): If hash table is being used and itype is visited,
3060 make an entry into table to link associated node and new itype.
3061 (Resolve_Record_Aggregate): Do not add an others box association for a
3062 discriminated record component that has only discriminants, when there
3063 is a box association for the component itself.
3065 * par-ch4.adb: Fix mishandling of multiple levels of parens

3100 Javier Miranda <miranda@adacore.com>
3101 Gary Dismukes <dismukes@adacore.com>
3103 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
3104 to make treatment of limited views uniform for all visible declarations
3105 in a limited_withed package.
3106 Improve warnings for in out parameters
3107 (Set_Related_Interaface/Related_Interface): Allow the use of this
3108 attribute with constants.
3109 (Write_Field26_Name): Handle attribute Related_Interface in constants.
3110 Warn on duplicate pragma Preelaborable_Initialialization
3112 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
3113 generation of a freezing node to ensure proper management of null
3114 excluding access types in the backend.
3115 (Create_Extra_Formals): Test base type of the formal when checking for
3116 the need to add an extra accessibility-level formal. Pass the entity E
3117 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
3118 originally being done in a couple of cases), to ensure that the
3119 Extra_Formals list gets set on the entity E when the first entity is
3121 (Conforming_Types): Add missing calls to Base_Type to the code that
3122 handles anonymous access types. This is required to handle the
3123 general case because Process_Formals builds internal subtype entities
3124 to handle null-excluding access types.
3125 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3126 functions that need it, even when not marked Requires_Overriding.
3127 Improve warnings for in out parameters
3128 (Analyze_Function_Return): Warn for disallowed null return
3129 Warn on return from procedure with unset out parameter
3130 Ensure consistent use of # in error messages
3131 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
3132 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
3133 the implicit conversion of the expression done for anonymous access
3134 types. This is required to generate the code of the null excluding
3135 check (if required).
3137 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
3138 A formal parameter is never publicly referenceable outside of its body.
3139 (Check_References): For an unreferenced formal parameter in an accept
3140 statement, use the same warning circuitry as for subprogram formal
3142 (Warn_On_Unreferenced_Entity): New subprogram, taken from
3143 Output_Unreferenced_Messages, containing the part of that routine that
3144 is now reused for entry formals as described above.
3145 (Goto_Spec_Entity): New function
3146 (Check_References): Do not give IN OUT warning for dispatching operation
3147 Improve warnings for in out parameters
3148 (Test_Ref): Check that the entity is not undefinite before calling
3149 Scope_Within, in order to avoid infinite loops.
3150 Warn on return from procedure with unset out parameter
3151 Improved warnings for unused variables

3154 Javier Miranda <miranda@adacore.com>
3155 Gary Dismukes <dismukes@adacore.com>
3157 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
3158 (Expand_N_Attribute_Reference): Further unify the handling of the
3159 three forms of access attributes, using common code now for all three
3160 cases. Add a test for the case of applying an access attribute to
3161 an explicit dereference when the context is an access-to-interface
3162 type. In that case we need to apply the conversion to the prefix
3163 of the explicit dereference rather than the prefix of the attribute.
3164 (Attribute_Version, UET_Address): Set entity as internal to ensure
3165 proper dg output of implicit importation.
3166 (Expand_Access_To_Type): Removed.
3167 (Expand_N_Attribute_Reference): Merge the code from the three cases
3168 of access attributes, since the processing is largely identical for
3169 these cases. The substantive fix here is to process the case of a
3170 type name prefix (current instance case) before handling the case
3171 of interface prefixes.
3173 2007-08-14 Thomas Quinot <quinot@adacore.com>
3174 Ed Schonberg <schonberg@adacore.com>
3175 Javier Miranda <miranda@adacore.com>
3176 Robert Dewar <dewar@adacore.com>
3178 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
3179 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
3180 type that is an anonymous access to controlled object, establish
3181 an associated finalization chain to avoid corrupting the global
3182 finalization list when a dynamically allocated object designated
3183 by such a component is deallocated.
3184 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3185 functions that need it, even when not marked Requires_Overriding.
3186 (Initialize_Tag): Replace call to has_discriminants by call to
3187 Is_Variable_Size_Record in the circuitry that handles the
3188 initialization of secondary tags.
3189 (Is_Variable_Size_Record): New implementation.
3190 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
3191 Suppress_Initialization pragma for a derived type.
3192 (Is_Variable_Size_Record): New subprogram.
3193 (Build_Offset_To_Top_Functions): New implementation that simplifies the
3194 initial version of this routine and also fixes problems causing
3195 incomplete initialization of the table of interfaces.
3196 (Build_Init_Procedure): Improve the generation of code to initialize the
3197 the tag components of secondary dispatch tables.
3198 (Init_Secondary_Tags): New implementation that simplifies the previous
3199 version of this routine.
3200 (Make_DT): Add parameter to indicate when type has been frozen by an
3201 object declaration, for diagnostic purposes.
3202 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
3203 diagnose attemps to freeze a subprogram when some untagged type of its
3204 profile is a private type whose full view has not been analyzed yet.
3205 (Freeze_Array_Type): Generate init proc for packed array if either
3206 Initialize or Normalize_Scalars is set.
3207 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
3208 constructing the new profile, copy the null_exclusion indicator for each
3209 parameter, to ensure full conformance of the new body with the spec.
3211 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
3212 Create wrappers for constructor functions that need it, even when not
3213 marked Requires_Overriding.
3214 (Covers): Handle properly designated types of anonymous access types,
3215 whose non-limited views are themselves incomplete types.
3216 (Add_Entry): Use an entity to store the abstract operation which hides
3218 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

3224 they are labeled as potentially hidden by an abstract operator.
3225 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
3226 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
3227 (Write_Overloads): Output the abstract operator if present.
3228 (Add_Entry): Before inserting a new entry into the interpretation table
3229 for a node, determine whether the entry will be disabled by an abstract
3231 (Binary_Op_Interp_May_Be_Hidden): New routine.
3232 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
3234 (Function_Interp_May_Be_Hidden): New routine.
3235 (Has_Compatible_Type): Do not consider interpretations hidden by
3236 abstract operators when trying to determine whether two types are
3238 (Has_Hidden_Interp): New routine.
3239 (Set_May_Be_Hidden_Interp): New routine.
3240 (Write_Overloads): Write the status of flag May_Be_Hidden.

3243 Javier Miranda <miranda@adacore.com>
3245 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
3246 types declared in the declarative part of a nested package body or in
3247 the proper body of a stub.

3252 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
3253 output of implicit importation and exportation.
3254 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
3255 first formal of the thunk is always associated with the controlling
3256 type. In addition perform the following code cleanup: remove formal
3257 Thunk_Alias which is no longer required, cleanup evaluation of the
3258 the controlling type, and update the documentation.
3259 Replace occurrence of Default_Prim_Op_Count by
3260 Max_Predef_Prims. Addition of compile-time check to verify
3261 that the value of Max_Predef_Prims is correct.
3262 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
3263 (Make_DT): Add parameter to indicate when type has been frozen by an
3264 object declaration, for diagnostic purposes.

3266 construction of statically allocated dispatch tables.
3267 (Make_DT): In case of library-level tagged types export the declaration
3268 of the primary tag. Remove generation of tags (now done by Make_Tags).
3269 Additional modifications to handle non-static generation of dispatch
3270 tables. Take care of building tables for asynchronous interface types
3271 (Make_Tags): New subprogram that generates the entities associated with
3272 the primary and secondary tags of Typ and fills the contents of Access_
3273 Disp_Table. In case of library-level tagged types imports the forward
3274 declaration of the primary tag that will be declared later by Make_DT.
3275 (Expand_Interface_Conversion): In case of access types to interfaces
3276 replace an itype declaration by an explicit type declaration to avoid
3277 problems associated with the scope of such itype in transient blocks.
3279 2007-08-14 Robert Dewar <dewar@adacore.com>
3280 Ed Schonberg <schonberg@adacore.com>
3281 Javier Miranda <miranda@adacore.com>
3283 * exp_util.ads, exp_util.adb:
3284 This patch replaces a number of occurrences of explicit tests for N_Null
3285 with calls to Known_Null. This improves tracking of null values, since
3286 Known_Null also catches null constants, and variables currently known to
3287 be null, so we get better tracking.
3288 (Ensure_Defined): create an itype reference only in the scope of the
3290 (Side_Effect_Free): A selected component of an access type that
3291 denotes a component with a rep clause must be treated as not
3292 side-effect free, because if it is part of a linked structure its
3293 value may be affected by a renaming.
3294 (Expand_Subtype_From_Expr): For limited objects initialized with build
3295 in place function calls, do nothing; otherwise we prematurely introduce
3296 an N_Reference node in the expression initializing the object, which
3297 breaks the circuitry that detects and adds the additional arguments to
3298 the called function. Bug found working in the new patch for statically
3299 allocated dispatch tables.
3300 (Is_Library_Level_Tagged_Type): New subprogram.
3301 (Remove_Side_Effects): If the expression of an elementary type is an
3302 operator treat as a function call.
3303 (Make_Literal_Range): If the index type of the array is not integer, use
3304 attributes properly to compute the constraint on the resulting aggregate
3307 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
3308 class-wide type whose base type is an incomplete private type, leave
3309 class-wide type unfrozen so that freeze nodes can be generated
3310 properly at a later point.
3311 (Freeze_Entity, array case): Handle case of pragma Pack and component
3312 size attributre clause for same array.

3372 source dirs are not known.
3373 (Check_Ada_Name): Allow all identifiers that are not reserved words
3375 Major update of the Project Manager and of the project aware tools,
3376 including gprmake, so that the same sources in the GNAT repository
3377 can be used by gprbuild.

3985 parameter to determine whether operation applies to the prefix.
3986 (Complete_Object_Operation): If actual has an access type and
3987 controlling formal is not an in_parameter, reject the actual if it is
3988 an access_to_constant type.
3989 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
3990 type, the candidate operations are found in the scope of declaration of
3991 the type, because the type has no primitive subprograms.
3992 (Analyze_Selected_Component): If prefix is class-wide, and root type is
3993 a private extension, only examine visible components before trying to
3994 analyze as a prefixed call.
3995 Change Entity_List to Type_To_Use, for better readability.

4009 purpose of enforcing E.2.2(8) only if it is not available at any place.
4010 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
4011 when checking the legality of an extension aggregate in a preelaborable
4012 package. Treat the literal null as a valid default expression in a
4013 component declaration for a type with preelaborable initialization.
4014 A limited interface is a legal progenitor for the designated type of a
4015 remote access to class-wide type.

4047 do not consider those that are hidden by abstract operators.
4048 (Resolve_Actuals): When verifying that an access to class-wide object
4049 is an actual for a controlling formal, ignore anonymous access to
4050 subprograms whose return type is an access to class_wide type.
4051 (Resolve_Slice): If the prefix of the slice is a selected component
4052 whose type depends on discriminants, build its actual subtype before

5229 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
5230 applicable to types that have the With_Type flag set. Returns the
5231 non-limited view of the type, if available, otherwise the type itself.

5233 to retrieve the class-wide type of the non-limited view of the Etype.
5234 New attributes Static_Initialization and Static_Elaboration_Desired.

5253 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
5254 class-wide types visible through limited-with clauses.
5255 (Try_Primitive_Operation): When examining all primitive operations of a
5256 tagged type, do not consider subprograms labeled as hidden unless they
5257 belong to a private generic type with a tagged parent.
5258 (Try_Object_Operation): Extensive rewriting, to handle properly various
5259 overloading cases, when several ancestors may have class-wide operations
5260 that are possible candidates, and when the overloaded functions return
5261 array types and have defaulted parameters so that the call may be
5262 interpreted as an indexing.
5263 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
5264 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
5265 successive actuals before analyzing the call itself.
5266 (Try_Primitive_Operation): A primitive operation is compatible with the
5267 prefix if the prefix has a synchronized type and the type of the formal
5268 is its corresponding record, as can be the case when the primitive
5269 operation is declared outside of the body of the type.
5270 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
5271 perform homonym traversal, looking for class-wide operation matches
5272 (formerly done in statements of Try_Class_Wide_Operation). Matches on
5273 access parameters are now restricted to anonymous access types.
5274 (Mark_Allocator): An allocator with a discriminant association parent is
5276 (Try_One_Prefix_Interpretation): If the type of the object is
5277 incomplete, as can be happen when it is a limited view obtained through
5278 a limited_with_clause, the selected component is not part of a prefixed
5280 (Complete_Object_Operation): Diagnose properly an object that is not
5281 aliased when the corresponding controlling formal is an access
5283 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
5284 ambiguous calls in prefixed notation, where two primitives differ only
5285 in that the controlling argument of one is an access parameter.
5287 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
5288 whether a function that returns an unconstrained type can be inlined.
5289 (Process_Formals): Diagnose properly the illegal use of an incomplete
5290 type in the profile of an access_to_subprogram declaration.
5291 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
5292 operations are attached to the corresponding record.
5293 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
5294 When processing a primitive of a concurrent type which implements an
5295 interface change the type of all controlling formals to that of the
5296 corresponding record type.
5297 (Check_Synchronized_Overriding): Relax the conditional logic when trying
5298 to determine the tagged type to which a primitive belongs.
5299 (Check_Conventions): Capture condition to ignore a primitive operation
5300 (which is shared between the loop in Check_Conventions and the one in
5301 Check_Convention) in a new local function Skip_Check.
5302 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
5303 confusion with Check_Conventions' own Prim_Op local variable.
5304 (Create_Extra_Formals): Test for a tagged result type rather than a
5305 controlling result when determining whether to add a BIP_Alloc_Form
5306 formal and a BIP_Final_List formal to the function.
5307 (Check_Conformance); For parameters that are anonymous access types,
5308 subtype conformance requires that the not null and the constant
5309 indicators must match
5310 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
5311 to retrieve the appropriate type when processing a concurrent type
5312 declared within a generic. Minor comment reformatting. Change invocation
5313 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
5315 (Analyze_Subprogram_Body): If the return type of a function is an
5316 anonymous access to the limited view of a class-wide type, and the
5317 non-limited view of the type is available, update the type of the
5318 function so that code can be generated.
5319 (Process_Formals): In case of access-subtype itype whose designated
5320 type is also an itype (situation that happens now with access to
5321 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
5322 attribute to avoid backend problems.
5323 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
5324 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
5325 anonymous types' designated types are same before testing
5326 Subtypes_Statically_Match.
5327 (Create_Extra_Formals): Test for a named access parameter that is a
5328 controlling formal as an additional condition for adding an
5329 accessibility level formal. This can occur in the subp type created for
5330 dispatching calls in Expand_Dispatching_Call, and allows calling
5331 Create_Extra_Formals from that procedure rather than special-casing the
5332 extra formals there.
5333 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
5334 when the function has a controlling result.
5335 (Check_Returns): Add much more knowledge of the optimization of local
5336 raise statements to gotos, to retain proper warnings in this case.
5337 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
5338 nodes when looking for last statement.
5340 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
5341 class-wide types visible through limited with clauses.
5342 (Add_One_Interp): If the operands are anonymous access types, the
5343 predefined operator on universal_access is immediately visibles
5344 (Find_Unique_Type): Handle anonymous access to subprogram types just as
5345 other anonymous access types.
5346 (Disambiguate): Take into account CIL convention.
5347 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
5349 2007-06-06 Robert Dewar <dewar@adacore.com>
5351 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
5352 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
5353 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
5354 Fix lower bound of tables.
5357 * nlists.adb: Ditto.
5358 (Prev_Node, Next_Node): Change index type to Int so that it properly
5359 covers the range First_Node_Id - 1 up.
5361 2007-06-06 Javier Miranda <miranda@adacore.com>
5362 Ed Schonberg <schonberg@adacore.com>
5363 Bob Duff <duff@adacore.com>
5364 Hristian Kirtchev <kirtchev@adacore.com>
5366 * exp_aggr.ads, exp_aggr.adb:
5367 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
5368 in extension aggregates.
5369 (Flatten): Other conditions being met, an aggregate is static if the
5370 low bound given by component associations is different from the low
5371 bound of the base index type.
5372 (Packed_Array_Aggregate_Handled): If the component type is itself a
5373 packed array or record, the front-end must expand into assignments.
5374 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
5375 Init_Pr, instead of Ancestor_Is_Expression.
5376 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
5377 coextension chain root, either generate a list controller or use the
5378 already existing one.
5379 (Static_Array_Aggregate): New procedure to construct a positional
5380 aggregate that can be handled by the backend, when all bounds and
5381 components are compile-time known constants.
5382 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
5383 types covering interface types into assignments.
5384 (Replace_Type): move to Build_Record_Aggr_Code.
5385 (Expand_Record_Aggr_Code): if the target of the aggregate is an
5386 interface type, convert to the definite type of the aggregate itself,
5387 so that needed components are visible.
5388 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
5389 components and the context is an extended return statement do not
5390 create a transient block for it, to prevent premature finalization
5391 before the return is executed.
5392 (Gen_Assign): Do not generate a call to deep adjust routine if the
5393 component type is itself an array of controlled (sub)-components
5394 initialized with an inner aggregate.
5395 (Component_Check): New name for Static_Check. This name is now more
5396 appropriate, and documentation is added which was missing.
5397 (Component_Check): Add test for bit aligned component value
5398 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
5399 Tagged_Comps, name is more appropriate given added function below.
5400 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
5402 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
5403 Javier Miranda <miranda@adacore.com>
5404 Robert Dewar <dewar@adacore.com>
5406 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
5407 Terminated: Add unchecked type conversion from System.Address to
5408 System.Tasking.Task_Id when calling the predefined primitive
5410 Disable new Ada 05 accessibility check for JVM.NET targets, which
5411 cannot be implemented in a practical way.
5412 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
5413 the sources always references the tag of the actual object. Therefore,
5414 if 'Tag is applied in the sources to class-wide interface objects we
5415 generate code that displaces "this" to reference the base of the object.
5416 (Expand_N_Attribute_Reference, case Size): Return specified size if
5418 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
5419 has code that displaces the pointer of the object to manage interface
5420 types. However this code must not be executed when the prefix is a
5421 subprogram. This bug caused the wrong expansion of the internally
5422 generated assignment that fills the dispatch table when the primitive
5423 is a function returning a class-wide interface type.
5424 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
5425 Set_Attribute_Name for Name_Unaligned_Valid.
5427 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5428 Gary Dismukes <dismukes@adacore.com>
5430 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
5431 If the initialization is the equivalent aggregate of the initialization
5432 procedure of the type, do not remove it.
5433 (Expand_N_Attribute_Definition_Clause): Exclude access variables
5434 initialized to null from having their expression reset to empty and
5435 note this exception in the comment.

5438 Robert Dewar <dewar@adacore.com>
5439 Ed Schonberg <schonberg@adacore.com>
5440 Gary Dismukes <dismukes@adacore.com>
5442 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
5443 Add "with" and "use" clauses for Sem_Attr.
5444 (Expand_Current_Value): Do not replace occurences of attribute
5445 references where the prefix must be a simple name.
5447 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
5448 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
5449 Attribute_Requires_Simple_Name_Prefix.
5450 (Name_Modifies_Prefix): Body of new function.
5451 (Requires_Simple_Name_Prefix): Body of new function.
5452 (Resolve_Attribute, case Access): Improve error message for case of
5453 mismatched conventions.
5454 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
5456 (Analyze_Attribute, case 'Access): If the type of the prefix is a
5457 constrained subtype for a nominal unconstrained type, use its base type
5458 to check for conformance with the context.
5459 (Resolve_Attribute): Remove test of the access type being associated
5460 with a return statement from condition for performing accessibility
5461 checks on access attributes, since this case is now captured by
5462 Is_Local_Anonymous_Access.
5463 (Analyze_Access_Attribute): Set Address_Taken on entity
5464 (Analyze_Attribute, case Address): Set Address_Taken on entity
5465 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
5466 validating an access attribute whose prefix is a current instance.
5467 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
5468 applied to dispatching operations, if freezing is required then we set
5469 the attribute Has_Delayed_Freeze in the prefix's entity.
5470 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
5471 current scope if access of local subprogram taken
5472 (Analyze_Access_Attribute): Check legality of self-reference even if the
5473 expression comes from source, as when a single component association in
5474 an aggregate has a box association.
5475 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
5476 the prefix if it is a protected operation and the attribute is
5477 Unrestricted_Access.
5478 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
5479 reference to the base type of the context, to force a constraint check
5480 when the context is an access subtype with an explicit constraint.
5481 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
5482 node is rewritten as an interface conversion. leave unanalyzed after
5483 resolution, to ensure that type checking against the context will take

5487 Javier Miranda <miranda@adacore.com>
5488 Robert Dewar <dewar@adacore.com>
5490 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
5491 wrapper when the full view of the controlling type of an inherited
5492 function that dispatches on result implements interfaces.
5493 (Expand_N_Object_Declaration): In cases where the type of the
5494 declaration is anonymous access, create finalization list for it.
5495 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
5496 if the object has no explicit initialization, to match description of
5497 functionality of pragam Persistent_BSS.
5498 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
5499 new function to build static aggregates, to replace initialization call
5500 when static initialization is desired.
5501 (Freeze_Type): Generate a list controller for an access type whenever
5502 its designated type has controlled anonymous access discriminants.
5503 (Build_Equivalent_Aggregate): New procedure to compute a static
5504 aggregate to be used as default initialization for composite types,
5505 instead of a generating a call to the initialization procedure for the
5507 (Build_Initialization_Call): When available, replace a call to the
5508 initialization procedure with a copy of the equivalent static aggregate
5510 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
5511 declarations for objects of a class-wide interface type, rather than
5512 just identifiers, to prevent visibility problems.
5513 (Expand_N_Object_Declaration): When expanding the declaration for an
5514 object of a class-wide interface type, preserve the homonym chain of
5515 the original entity before exchanging it with that of the generated
5516 renaming declaration.
5517 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
5518 active, because there is no way to handle the exception.
5519 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
5520 to do a minimum decoration of the Access_Disp_Table list.
5521 (Expand_Record_Controller): Avoid the addition of the controller between
5522 the component containing the tag of a secondary dispatch table and its
5523 adjacent component that stores the offset to the base of the object.
5524 This latter component is only generated when the parent type has
5525 discriminants ---documented in Add_Interface_Tag_Components).
5526 (Apply_Array_Size_Check): Removed, no longer needed.
5527 (Expand_N_Full_Type_Declaration): If the type has anonymous access
5528 components, create a Master_Entity for it only if it contains tasks.
5529 (Build_Init_Procedure): Suppress the tag assignment compiling under
5531 (Freeze_Record_Type): Remove code associated with creation of dispatch
5533 (Init_Secondary_Tags): Update type of actuals when generating calls to
5534 Ada.Tags.Set_Offset_To_Top
5535 (Stream_Operation_OK): Disable use of streams compiling under no
5537 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
5538 if Has_Init_Expression set.
5539 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
5540 Register_Primitive, which provides the same functionality.
5541 (Requires_Init_Proc): Return false in case of interface types.
5542 (Add_Secondary_Tables): Use the new attribute Related_Interface to
5544 (Predefined_Primitive_Freeze): Do not assume that an internal entity
5545 is always associated with a predefined primitive because the internal
5546 entities associated with interface types are not predefined primitives.
5547 Therefore, the call to Is_Internal is replaced by a call to the
5548 function Is_Predefined_Dispatching_Operation.
5549 (Make_Eq_If): When generating the list of comparisons for the
5550 components of a given variant, omit the controller component that is
5551 present if the variant has controlled components.
5553 2007-06-06 Javier Miranda <miranda@adacore.com>
5554 Hristian Kirtchev <kirtchev@adacore.com>
5555 Bob Duff <duff@adacore.com>
5557 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
5558 handle the creation of finalization lists and calls for nested
5559 coextensions when the root of the chains is part of a return statement.
5560 (Inside_A_Return_Statement): New function inside Complete_Coextension_
5562 (Expand_Record_Equality): Skip components that are interface types.
5563 (Displace_Allocator_Pointer): Add missing support for interface subtypes
5564 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
5565 with Rewrite_Coextension. Change the condition for detecting coextension
5567 (Is_Local_Access_Discriminant): Removed.
5568 (Rewrite_Coextension): New routine which rewrites a static coextension
5569 as a temporary and uses its unrestricted access in the construction of
5571 (Complete_Coextension_Finalization): New routine. Generate finalization
5572 attachment calls to all delayed coextensions.
5573 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
5574 the allocator is not a coextension itself and has delayed coextensions.
5575 If the current allocator is controlled, but also a coextension, delay
5576 the generation of the finalization attachment call.
5577 Rename local variable "Node" to "Nod" in order to avoid confusion with
5579 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
5580 limited types that are not inherently limited. Such an allocator is
5581 illegal, but is generated by the expander for a return statement, to
5582 copy the result onto the secondary stack. This is the only case where a
5583 limited object can be copied. Generate code to displace the pointer
5584 to the object if the qualified expression is a class-wide interface
5585 object. Such displacement was missing and hence the copy of the object
5587 (Apply_Accessibility_Check): Handle allocated objects initialized in
5589 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
5590 and Expand_Allocator_Expression. Allocating class-wide interface objects
5591 this routine displaces the pointer to the allocated object to reference
5592 the component referencing the corresponding secondary dispatch table.
5593 Expand_Allocator_Expression): Add missing support to allocate class-wide
5594 interface objects initialized with a qualified expression.
5595 (Get_Allocator_Final_List): Test for an anonymous access type that is a
5596 function result type, and use the finalization list associated with the
5597 function scope in that case (such an anonymous type should not be
5598 treated like an access parameter's type).
5600 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5601 Gary Dismukes <dismukes@adacore.com>
5602 Javier Miranda <miranda@adacore.com>
5604 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
5605 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
5606 required exception handler.
5607 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
5608 properly the case of a function whose return type is a limited
5609 class-wide interface type. Modify the code of the accessibility
5610 check to handle class-wide interface objects. In this case we need to
5611 displace "this" to reference the primary dispatch table to get access
5612 to the TSD of the object (to evaluate its accessibility level).
5613 (Expand_N_Extended_Return_Statement): Test for a tagged result type
5614 rather than a controlling result as one of the conditions for
5615 generating tests of the implicit BIP_Alloc_Form formal. The
5616 initialization assignment is also handled according to whether the
5617 result is tagged instead of controlling.
5618 In the case where the init assignment is inserted in the "then" part of
5619 the allocation conditional, rewrite the target to be a dereference of
5620 the implicit BIP_Object_Access formal.
5621 If the returned value is unconstrained and created on the secondary
5622 stack, mark the enclosing block and function so that the secondary
5623 stack is not reclaimed on return.
5624 Treat returns from functions with controlling results similarly to
5625 returns from functions with unconstrained result subtypes.
5626 If the object returned is unconstrained, and an allocator must be
5627 created for it, analyze the allocator once the block for the extended
5628 return is installed, to ensure that finalizable components
5629 of the expression use the proper finalization list. Guard the call to
5630 Move_Final_List with a check that there is something to finalize.
5631 (Make_Tag_Ctrl_Assignment): Use "old" handling
5632 of controlled type assignment for virtual machines, since new code uses
5633 unsupported features (such as direct access to bytes in memory).
5635 2007-06-06 Gary Dismukes <dismukes@adacore.com>
5636 Ed Schonberg <schonberg@adacore.com>
5638 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
5639 accessibility actual, check for the case of an aliased object that has
5640 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
5641 we fall into processing for the attribute rather than the name of the
5643 (Expand_Inline_Call): If an actual is a literal, and the corresponding
5644 formal has its address taken in the body, create a temporary to capture
5645 value. If the return type is a limited interface, do not treat the
5646 return value as Controlled.
5647 (Is_In_Place_Function): If the return type is a limited interface,
5648 treat as returning in place. The actual returned object may not always
5649 be limited, but the caller has to assume that it is returned in place.
5650 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
5651 context of an allocator, use the correct finalization chain (that is,
5652 the chain belonging to the access type, rather than the chain belonging
5653 to the current scope).
5654 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
5655 result type rather than a controlling result as a precondition for
5656 adding an allocation form actual to a build-in-place call.
5657 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
5658 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
5659 primitive in the dispatch tables. This work is now done by Make_DT when
5661 (Register_Predefined_DT_Entry): Removed.
5662 (Add_Return): If end label is not present, use sloc of last statement
5663 for generated return statement in procedure, for better gdb behavior
5665 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
5666 object address nodes to ensure proper processing by routines like
5668 (Expand_Call): Fix generation of validity check for parameter
5669 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
5670 the allocation form parameter if the result subtype is constrained,
5671 except when the function has a controlling result.
5672 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
5673 rather than Is_Controlled and Has_Controlled_Component, since we want to
5674 include class-wide result types in this treatment. Also test for a
5675 controlling result, since that also requires passing a finalization
5677 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
5678 even when the result subtype is constrained, to handle calls involving
5679 controlling results.
5680 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
5681 is now called even when the result subtype is constrained, to handle
5682 calls involving controlling results.
5683 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
5684 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
5685 now performs the test).
5686 (Make_Build_In_Place_Call_In_Object_Declaration):
5687 Add_Alloc_Form_Actual_* is now called even when the result subtype is
5688 constrained, to handle calls involving controlling results.
5689 (Add_Return): Accomodate rewritten pattern from local raise to goto
5690 transformation, so that we still recognize an transfer statement
5691 and do the right thing here in that case.
5692 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
5693 and end of subprogram code.
5694 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
5695 support for primitives that are functions (without formals) with a
5697 (Inherited_From_Formal): If the actual subtype has not generic parent
5698 type, it is not an actual for a formal derived type, and there is no
5699 operation to inherit from the formal.
5701 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5702 Thomas Quinot <quinot@adacore.com>
5704 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
5705 inserted cleanup code appropriately for GDB use.
5706 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
5707 exception handler for Deep_Adjust or Deep_Finalize.
5708 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
5709 Raise_From_Controlled_Operation is available, use a call to that
5710 subprogram instead of a plain "raise Program_Error" node to raise
5711 Program_Error if an exception is propagated from an Adjust or Finalize
5713 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
5714 appears in the optional statement list of a triggering alternative, the
5715 scope actions can be inserted directly there, and not in the list that
5716 includes the asynchronous select itself.

5720 Hristian Kirtchev <kirtchev@adacore.com>
5722 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
5723 generated exception handler appropriately when debugging generated code.
5724 Deal properly with No_Exception_Propagation restriction mode.
5725 (Expand_N_Abort_Statement): Add an unchecked type conversion from
5726 System.Address to System.Tasking.Task_Id when processing the result of
5727 the predefined primitive _disp_get_task_id.
5728 (Expand_N_Asynchronous_Select): Clarify comment.
5729 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
5730 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
5731 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
5732 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
5733 privals and for generated call to Complete_Entry_Body, for better gdb
5735 (Copy_Result_Type): Utility to construct a parameter and result profile
5736 for protected functions whose return type is an anonymous access to
5738 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
5740 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
5741 point when the local-raise-to-goto transformation has taken place.
5743 2007-06-06 Javier Miranda <miranda@adacore.com>
5744 Nicolas Setton <setton@adacore.com>
5746 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
5747 functionality when the backend is generating code.
5748 Otherwise any serious error
5749 reported by the backend calling the frontend routine Error_Msg
5750 changes the Compilation_Mode to Check_Semantics, disables the
5751 functionality of this routine and causes the generation of
5752 spureous additional errors.
5754 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
5755 debugging information now generated by the compiler for fat-pointer
5757 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
5759 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
5761 2007-06-06 Thomas Quinot <quinot@adacore.com>
5763 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
5764 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
5765 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
5766 For a remote call to a function with a classwide return type, apply an
5767 E.4(18) check to the returned value.
5768 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
5769 stream attributes of the designated type of an RACW, as they are not

5892 subtype from the function call, as is done for private types.
5893 (Side_Effect_Free): An expression that is the renaming of an object or

7757 to handle properly the anonymous access case.
7759 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
7760 for all access attributes, because overload resolution should work the
7761 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
7762 causes the error message for the ambiguous "X'Access = Y'Access" and
7763 "X'Unrestricted_Access = Y'Access" and so forth to match.
7764 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
7765 now that anonymous access to protected operations have their own kind.

7779 Check_Anonymous_Access_Components rather than Empty.
7780 (Make_Incomplete_Type_Declaration): Add test for case where the type has
7781 a record extension in deciding whether to create a class-wide type,

7862 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
7863 when -gnatg is not specified.

7915 parameter of the containing subprogram.
7916 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
7917 under No_Dispatching_Calls restriction. During the semantic analysis
7918 we already notified such violation.

7936 initialize most the TSD components by means of an aggregate.
7937 Modify the declaration of the object containing the TSD
7938 because we now expand code that has a higher level of abstraction.
7939 The TSD has a discriminant containing the Inheritance Depth Level,
7940 value that is used in the membership test but also to fix the size
7941 of the table of ancestors.
7942 (Expand_Interface_Conversion): Insert function body at the closest place
7943 to the conversion expression, to prevent access-before-elaboration

8000 support concurrent types implementing interfaces.
8001 (Find_Implemented_Interface): Removed. All the calls to this subprogram

8005 CW_Or_Controlled_Type whenever the issue is related to
8006 using or not the secondary stack.

8100 * Retrieve the extra formals parameters at the
8101 end of the parameter stream.
8102 * Use Move_Any_Value to write back out parameters

8123 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
8124 typecode from the Etype. Therefore we retrieve the correct typecode
8125 with a call to Get_Any_Type.
8126 (Copy_Specification): Do controlling formal type substitution based on
8127 Is_Controlling_Formal flag, instead of caller-provided object type.
8128 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
8129 a RACW primitive operation, we might get a subprogram declaration for an
8130 ancestor of the RACW designated type (not for the designated type
8131 itself), in the case where this operation is inherited. In this case we
8132 have no easy means of determining the original tagged type for which
8133 the primitive was declared, so instead we now rely on
8134 Copy_Specification to use the Is_Controlling_Formal flag to determine
8135 which formals require type substitution.

8144 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
8145 run-time subprogram CW_Membership by call to Build_CW_Membership.
8146 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
8147 by a function call, a temporary must be created before expanding the
8148 Constructor_Call itself, to prevent out-of-order elaboration in the
8149 back-end when stack checking is enabled..

8596 unit, in which case the instance must be analyzed with the latest Ada
8597 mode. This setting must take place after analysis of the actuals,
8598 because the actuals must be analyzed and frozen in the Ada mode extant
8599 outside of the current instantiation.

8619 non-limited view is available, use the non-limited one.
8620 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
8621 therefore illegal), suggest a qualified expression rather than a type
8622 conversion, because a type conversion would be illegal in this context.
8623 (Anayze_Allocator): Trace recursively all nested allocators so that all
8624 coextensions are on the corresponding list for the root. Do no mark
8625 coextensions if the root allocator is within a declaration for a stack-
8626 allocated object, because the access discriminants will be allocated on
8628 (Analyze_Call): Remove restriction on calls to limited functions for the
8629 cases of generic actuals for formal objects, defaults for formal objects
8630 and defaults for record components.
8631 (Analyze_Allocator): Before analysis, chain coextensions on the proper
8632 element list. Their expansion is delayed until the enclosing allocator
8633 is processed and its finalization list constructed.
8634 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
8635 for an operation with the given name among the primitive operations of
8636 the corresponding record type.
8637 (Analyze_Selected_Component): If the prefix is a task type that
8638 implements an interface, and there is no entry with the given name,
8639 check whether there is another primitive operation (e.g. a function)
8641 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
8642 properly the indexing of a function call written in prefix form, where
8643 the function returns an array type, and all parameters of the function
8644 except the first have defaults.
8645 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
8646 the original operands, rather than relocating them, for efficiency and
8647 to work properly when an operand is overloaded.
8648 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
8649 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
8650 (Analyze_Selected_Component): If the prefix is a private extension, only
8651 scan the visible components, not those of the full view.
8652 (Try_Primitive_Operation): If the operation is a procedure, collect all
8653 possible interpretations, as for a function, because in the presence of
8654 classwide parameters several primitive operations of the type can match
8655 the given arguments.

8666 Thomas Quinot <quinot@adacore.com>
8668 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move

8670 to package bodies as well, for deferred constants completed by pragmas.
8671 (Analyze_Package_Declaration): When the package declaration being
8672 analyzed does not require an explicit body, call Check_Completion.
8673 (May_Need_Implicit_Body): An implicit body is required when a package
8674 spec contains the declaration of a remote access-to-classwide type.
8675 (Analyze_Package_Body): If the package contains RACWs, append the
8676 pending subprogram bodies generated by exp_dist at the end of the body.
8677 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
8678 Is_Abstract_Subprogram and Is_Abstract_Type.

8680 that must be preserved from full to partial view.
8682 * sem_dist.adb (Add_RAS_Dereference_TSS):
8683 Change primitive name to _Call so it cannot clash with any legal
8684 identifier, and be special-cased in Check_Completion.
8685 Mark the full view of the designated type for the RACW associated with
8686 a RAS as Comes_From_Source to get proper view switching when installing
8687 private declarations.
8688 Provite a placeholder nested package body along with the nested spec
8689 to have a place for Append_RACW_Bodies to generate the calling stubs
8690 and stream attributes.

8719 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
8720 dereference of a local object R created as a reference to another
8721 object O, use the access level of O.
8722 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
8723 rather than local Same_Formal_Type, to check whether protected operation
8724 overrides an inherited one.
8725 (Same_Formal_Type): New predicate, used when matching signatures of
8726 overriding synchronized operations, to handle the case when a formal
8727 has a type that is a generic actual.
8728 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
8729 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
8730 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
8731 syntactic ambiguities involving indexing of function calls that return
8733 (Abstract_Interface_List): New subprogram that returns the list of
8734 abstract interfaces associated with a concurrent type or a
8735 concurrent record type.
8736 (Interface_Present_In_Parent): New subprogram used to check if a
8737 given type or some of its parents implement a given interface.
8738 (Collect_Abstract_Interfaces): Add support for concurrent types
8739 with interface types.
8740 (Has_Abstract_Interfaces): Add support for concurrent types with
8742 (Is_Parent): New subprogram that determines whether E1 is a parent
8743 of E2. For a concurrent type its parent is the first element of its
8744 list of interface types; for other types this function provides the
8745 same result than Is_Ancestor.
8746 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
8747 (Collect_Synchronized_Interfaces): Removed because the subprogram
8748 Collect_Abstract_Interfaces provides this functionality.
8749 (Collect_Abstract_Interfaces): Minor update to give support to
8750 concurrent types and thus avoid undesired code duplication.
8751 (Get_Subprogram_Entity): Handle entry calls.
8752 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
8754 (Enter_Name): Do not give -gnatwh hiding warning for record component

8792 the call directly here.
8793 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
8794 high bound is constant and the slice is empty. Tidy.
8795 (tree_transform, case N_Op_Not): Handle properly the case where the
8796 operation applies to a private type whose full view is a modular type.
8797 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
8798 Address_Clause, use the associated Expression as the GNAT tree
8799 representing the choice value to ensure the corresponding GCC tree is
8801 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
8802 instead of just the operands, as the base GCC stabilize_reference does.
8803 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
8804 requested; otherwise fail.
8805 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

9062 universal_fixed "*" and "/" operators when they are used in a context
9063 that expects any real type. Also set the type of the node to

9065 (mainly static expression evaluation).
9066 Reword some continuation messages
9067 Add some \\ sequences to continuation messages
9068 (Resolve_Call): Refine infinite recursion case. The test has been
9069 sharpened to eliminate some false positives.

9073 is an inherited operation.
9074 (Check_Aggr): When resolving aggregates, skip associations with a box,

9078 a class-wide interface to a tagged type. Minor code cleanup.
9079 (Valid_Tagged_Converion): Add support for abstact interface type

9082 during analysis, and use May_Be_Lvalue to distinguish read/write.
9083 (Valid_Array_Conversion): New procedure, abstracted from
9084 Valid_Conversion, to incorporate accessibility checks for arrays of
9085 anonymous access types.
9086 (Valid_Conversion): For a conversion to a numeric type occurring in an
9087 instance or inlined body, no need to check that the operand type is
9088 numeric, since this has been checked during analysis of the template.
9089 Remove legacy test for scope name Unchecked_Conversion.
9091 * sem_res.ads: Minor reformatting

9553 is the upper case first character of the policy name.
9554 (__gnat_set_globals): Now a dummy function.
9555 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
9556 mechargs instead of sigargs, as the latter can be retrieved from the

9560 (__gnat_adjust_context_for_raise, ia64-vms): New function.
9561 (tasking_error): Remove unused symbol.

9565 this is the only target that uses this definition.
9566 (Lock_Task): Remove unused symbol.

9617 alias of a predefined dispatching primitive.
9618 (Make_DT): If the ancestor of the type is a CPP_Class and we are
9619 compiling under full ABI compatibility mode we avoid the generation of
9620 calls to run-time services that fill the dispatch tables because under
9621 this mode we currently inherit the dispatch tables in the IP subprogram.
9622 (Write_DT): Emit an "is null" indication for a null procedure primitive.
9623 (Expand_Interface_Conversion): Use an address as the type of the formal

9676 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
9677 assignments where the target subtype is unconstrained and the target
9678 object is a parameter or dereference (other aliased cases are known
9679 to be unconstrained).

9800 nested at any level.
9801 (Is_Self_Referential_Init): Remove, not needed.

9805 check for presence of entity before checking for self-reference.
9806 (Has_Default_Init_Comps): Return True if a component association is a
9807 self-reference to the enclosing type, which can only come from a
9808 default initialization.
9809 (Make_OK_Assignment_Statement): If the expression is of the form
9810 Typ'Acc, where Acc is an access attribute, the expression comes from a
9811 default initialized self-referential component.
9812 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
9813 that has been derived from several abstract interfaces we must also
9814 initialize the tags of the secondary dispatch tables.

9819 Robert Dewar <dewar@adacore.com>
9822 (Expand_Access_To_Protected_Op): If the context indicates that an access

9843 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
9844 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
9845 an aliased prefix must be known to be constrained in order to use True
9846 for the attribute value, and now it's possible for some aliased views
9847 to be unconstrained.
9849 2006-10-31 Robert Dewar <dewar@adacore.com>
9851 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue

9865 generate the wrapper if the parent primitive is abstract. This is
9866 required to report the correct error message.
9867 (Expand_N_Subtype_Indication): Do validity checks on range
9868 (Clean_Task_Names): If an initialization procedure includes a call to
9869 initialize a task (sub)component, indicate that the procedure will use

9872 compatibility for interfacing with CPP by default.
9873 (Expand_N_Object_Declaration): Only build an Adjust call when the

9875 * exp_ch3.adb: Add with and use of Exp_Ch6.
9876 (Expand_N_Object_Declaration): Check for object initialization that is a
9877 call to build-in-place function and apply Make_Build_In_Place_Call_In_
9878 Object_Declaration to the call.
9879 (Freeze_Type): When the designated type of an RACW was not frozen at the
9880 point where the RACW was declared, validate the primitive operations

9882 (Build_Initialization_Call,Expand_Record_Controller): Rename
9883 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
9884 return-by-reference has no meaning in Ada 2005.

9893 Insert_List_Before_And_Analyze after the generation of the specs
9894 associated with null procedures.
9895 (Expand_Tagged_Root): Update documentation in its specification.
9896 (Init_Secondary_Tags): Update documentation.
9897 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
9898 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
9899 then generate code to inherit the contents of the dispatch table
9900 directly from the ancestor.
9901 (Expand_Record_Controller): Insert controller component after tags of
9902 implemented interfaces.
9903 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
9904 create null procedure overridings when null procedures are inherited

9907 declarations for overriding null primitives inherited from interfaces.
9908 (Is_Null_Interface_Procedure): New function in

9910 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
9911 immediate ancestor of a tagged type is an abstract interface type we
9912 must generate the specification of the predefined primitives associated
9913 with controlled types (because the dispatch table of the ancestor is
9914 null and hence these entries cannot be inherited). This is required to
9915 elaborate well the dispatch table.

9926 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
9927 (Expand_N_Allocator): For "new T", if the object is constrained by
9928 discriminant defaults, allocate the right amount of memory, rather than
9929 the maximum for type T.
9930 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
9931 when the allocator is initialized by a build-in-place call, since the
9932 allocator is already rewritten as a reference to the function result,
9933 and this prevents an unwanted duplication of the function call.
9934 Add with and use of Exp_Ch6.
9935 (Expand_Allocator_Expresssion): Check for an allocator whose expression
9936 is a call to build-in-place function and apply
9937 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
9938 untagged designated types).
9939 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
9940 optimization if source or target is biased.

9954 (Expand_N_Assignment_Statement): Call
9955 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
9956 build-in-place function call. Currently, this can happen only for
9957 assignments that come from aggregates.
9958 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
9959 in order to alleviate the upward compatibility introduced by AI-318.
9960 (Expand_N_Extended_Return_Statement): Add support for handling the
9961 return object as a build-in-place result.
9962 (Expand_Non_Function_Return): Implement simple return statements nested
9963 within an extended return.
9964 (Enable_New_Return_Processing): Turn on the new processing of return
9966 (Expand_Non_Function_Return): For a return within an extended return,

9975 validity checking of assignments to elementary record components.
9976 (Expand_N_Return_Statement): return Class Wide types on the secondary
9977 stack independantly of their controlled status since with HIE runtimes,
9978 class wide types are not potentially controlled anymore.
9980 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
9983 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
9984 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
9985 it expects a block, procedure, or task. The return statement will get
9986 turned into a block, and Expand_Cleanup_Actions will happen then.

9993 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
9995 (Expand_Inlined_Call): Tagged types are by-reference types, and
9996 therefore should be replaced by a renaming declaration in the expanded
9997 body, as is done for limited types.
9998 (Expand_Call): If this is a call to a function with dispatching access
9999 result, propagate tag from context.
10000 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
10002 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
10003 build-in-place when the right-hand side of an assignment is a
10004 build-in-place function call.
10005 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
10006 of the explicit dereference of the allocator to the result subtype of
10007 the build-in-place function. This is needed to satisfy type checking
10008 in cases where the caller's return object is created by an allocator for
10009 a class-wide access type and the type named in the allocator is a
10011 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
10012 conversion of the reference to the declared object to the result subtype
10013 of the build-in-place function. This is needed to satisfy type checking
10014 in cases where the declared object has a class-wide type. Also, in the
10015 class-wide case, change the type of the object entity to the specific
10016 result subtype of the function, to avoid passing a class-wide object
10017 without explicit initialization to the back end.
10018 (Register_Interface_DT_Entry): Moved outside the body of
10019 Freeze_Subprogram because this routine is now public; it is called from
10020 Check_Dispatching_Overriding to handle late overriding of abstract
10021 interface primitives.
10022 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
10023 adding an implicit access actual on a call to a build-in-place function.
10024 (Expand_Actuals): Test for an actual parameter that is a call to a
10025 build-in-place function and apply
10026 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
10027 (Is_Build_In_Place_Function): New function to determine whether an
10028 entity is a function whose calls should be handled as build-in-place.
10029 (Is_Build_In_Place_Function_Call): New function to determine whether an
10030 expression is a function call that should handled as build-in-place.
10031 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
10032 calls to build-in-place functions as the initialization of an allocator.
10033 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
10034 handling calls to build-in-place functions in contexts that do not
10035 involve init of a separate object (for example, actuals of subprogram
10037 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
10038 handling calls to build-in-place functions as the initialization of an
10039 object declaration.
10040 (Detect_Infinite_Recursion): Add explicit parameter Process to
10041 instantiation of Traverse_Body to avoid unreferenced warning.
10042 (Check_Overriding_Inherited_Interfaces): Removed.
10043 (Register_Interface_DT_Entry): Code cleanup.
10044 (Register_Predefined_DT_Entry): Code cleanup.
10045 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
10046 inlined statements if within a transient scope.
10047 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
10048 formal parameters with occurrences of actuals in inlined body, establish
10049 visibility on the proper view of the actual's subtype for the body's
10051 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
10052 compatibility mode and we have an imported CPP subprogram because
10053 for now we assume that imported CPP primitives correspond with
10054 objects whose constructor is in the CPP side (and therefore we
10055 don't need to generate code to register them in the dispatch table).
10056 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
10057 aligned selected component.
10058 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
10059 the actual of an in-mode parameter is a type conversion.
10060 (Expand_Actuals): If the call does not come from source and the actual
10061 is potentially misaligned, let gigi handle it rather than rejecting the
10062 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
10063 Class Wide types as returning by reference independantly of their
10064 controlled status since with HIE runtimes class wide types are not
10065 potentially controlled anymore.
10067 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10069 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity

10080 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
10081 initialization of Homonym_Len.
10082 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
10083 names from fully qualified name. Fixes problem of duplicate
10084 external names differing only in the presence of such a block name.

10087 Pablo Oliveira <oliveira@adacore.com>
10089 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
10090 subprogram Ids, even if they are not yet assigned.
10091 (Build_Subprogram_Id): It is now this function that will take care of
10092 calling Assign_Subprogram_Ids if necessary.
10093 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
10094 should be done only once they are assigned.
10095 (Build_From_Any_Function, case of tagged types): Add missing call to
10097 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
10098 type for an RACW type.
10099 (Add_RACW_Features): When processing an RACW declaration for which the
10100 designated type is already frozen, enforce E.2.2(14) rules immediately.
10101 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
10102 special reordering of controlling formals.
10104 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
10105 associated stub type for an RACW type.
10107 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10109 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
10110 fixed-point operations in an integer context, i.e. as operands of a
10111 conversion to an integer type, indicate that result must be rounded.
10113 2006-10-31 Robert Dewar <dewar@adacore.com>
10115 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
10116 cases, pass the encoding method, since it is now required by the run
10119 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
10120 assumption that Str'First = 1.
10121 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
10122 it on to the Value_Wide_Wide_Character call.
10123 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
10124 properly handles a string of the form quote-encoded_wide_char-quote.
10126 * s-wchcnv.adb: Minor reformatting
10128 2006-10-31 Javier Miranda <miranda@adacore.com>
10130 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
10131 run-time membership test to ensure that the constructed object
10132 implements the target abstract interface.
10134 2006-10-31 Robert Dewar <dewar@adacore.com>
10136 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
10137 Machine_Attribute pragma internally to implement the user pragma.
10138 Add processing for pragma Interface so that it is now completely
10139 equivalent to pragma Import.
10141 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
10142 so that it can be applied to all entities, including record components
10143 and enumeration literals.
10144 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
10145 priority ranges are correct, verify compatibility against task
10146 dispatching and locking policies, and if everything is correct an entry
10147 is added to the table containing priority specific dispatching entries
10148 for this compilation unit.
10149 (Delay_Config_Pragma_Analyze): Delay processing
10150 Priority_Specific_Dispatching pragmas because when processing the
10151 pragma we need to access run-time data, such as the range of
10152 System.Any_Priority.
10153 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
10154 Allow pragma Unreferenced as a context item
10155 Add pragma Preelaborable_Initialization
10156 (Analyze_Pragma, case Interface): Interface is extended so that it is
10157 now syntactically and semantically equivalent to Import.
10158 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
10159 insertion characters.
10160 Add handling for Pragma_Wide_Character_Encoding
10161 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
10162 never supercedes a real restriction, and that a real restriction
10163 always supercedes a warning.
10164 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

10171 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
10172 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
10173 Is_Inherently_Limited_Type, because return-by-reference has no meaning
10175 (Find_Node_To_Be_Wrapped): Use new method of determining the result
10176 type of the function containing a return statement, because the
10177 Return_Type field was removed. We now use the Return_Applies_To field.
10179 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
10180 (Build_Task_Image_Decl): If procedure is not called from an
10181 initialization procedure, indicate that function that builds task name
10182 uses the sec. stack. Otherwise the enclosing initialization procedure
10183 will carry the indication.
10184 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
10185 N_Object_Declaration instead.
10186 (Kill_Dead_Code): New interface to implement -gnatwt warning for
10187 conditional dead code killed, and change implementation accordingly.
10188 (Insert_Actions): Add N_Return_Object_Declaration case.
10189 Correct comment to mention N_Extension_Aggregate node.
10190 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
10191 attempts to save information for global variables which cannot be
10193 (Get_Current_Value_Condition): Handle conditions the other way round
10194 (constant on left). Also handle right operand of AND and AND THEN
10195 (Set_Current_Value_Condition): Corresponding changes
10196 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
10197 (Get_Current_Value_Condition): Handle simple boolean operands
10198 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
10199 (Get_Current_Value_Condition): If the variable reference is within an
10200 if-statement, does not appear in the list of then_statments, and does
10201 not come from source, treat it as being at unknown location.
10202 (Get_Current_Value_Condition): Enhance to allow while statements to be
10203 processed as well as if statements.
10204 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
10206 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
10207 of loop. This is safe now that we fixed Kill_Current_Values.
10208 (OK_To_Do_Constant_Replacement): Check whether current scope is
10209 Standard, before examining outer scopes.
10211 2006-10-31 Vincent Celier <celier@adacore.com>
10213 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
10214 When True, apply VMS treatment to children of packages A, G, I and S.

10226 * g-comlin.adb: Add Warnings (Off) to prevent new warning
10228 * g-expect.adb: Add Warnings (Off) to prevent new warning

10231 (Generate_Reference): Centralize handling of pragma Obsolescent here
10232 (Generate_Reference): Accept an implicit reference generated for a
10233 default in an instance.
10234 (Generate_Reference): Accept a reference for a node that is not in the
10235 main unit, if it is the generic body corresponding to an subprogram
10238 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
10240 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
10242 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
10244 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
10245 use clauses, to avoid messages on packages used to qualify, and also
10246 to avoid messages from obsolescent units.
10247 (Warn_On_Useless_Assignments): Don't generate messages for imported
10248 and exported variables.
10249 (Warn_On_Useless_Assignments): New procedure

10255 (Last_Assignment): New field for useless assignment warning
10257 2006-10-31 Olivier Hainque <hainque@adacore.com>
10259 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
10260 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
10262 2006-10-31 Bob Duff <duff@adacore.com>
10263 Robert Dewar <dewar@adacore.com>
10264 Ed Schonberg <schonberg@adacore.com>
10266 * g-awk.adb (Default_Session, Current_Session): Compile this file in
10267 Ada 95 mode, because it violates the new rules for AI-318.
10269 * g-awk.ads: Use overloaded subprograms in every case where we used to
10270 have a default of Current_Session. This makes the code closer to be
10271 correct for both Ada 95 and 2005.
10273 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
10274 code, relying on the fact that the compiler generates a warning
10275 instead of an error in -gnatg mode.
10277 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
10278 E_Return_Statement entity kind.
10279 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
10281 * par.adb (P_Interface_Type_Definition): Addition of one formal to
10282 report an error if the reserved word abstract has been previously found.
10283 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
10285 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
10286 parenthesized range attribute usage
10287 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
10289 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
10290 in the syntax for extended_return_statement. This is not in the latest
10291 RM, but the ARG is expected to issue an AI allowing this.
10292 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
10293 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
10294 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
10295 P_Return_Statement): Parse the new syntax for extended_return_statement.
10297 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
10298 Output_End_Missing): Add error-recovery code for the new
10299 extended_return_statement syntax; that is, the new E_Return entry on
10302 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
10303 limited to nonlimited, because otherwise we violate the new Ada 2005
10304 rules about returning limited types in function Create_AST_Handler in
10307 * sem.adb (Analyze): Add cases for new node kinds
10308 N_Extended_Return_Statement and N_Return_Object_Declaration.
10310 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
10311 type is in the same category as type of context before applying check,
10312 to prevent anomalies in instantiations.
10313 (Resolve_Aggregate): Remove test for limited components in aggregates.
10314 It's unnecessary in Ada 95, because if it has limited components, then
10315 it must be limited. It's wrong in Ada 2005, because limited aggregates
10317 (Resolve_Record_Aggregate): Move check for limited types later, because
10318 OK_For_Limited_Init requires its argument to have been resolved.
10319 (Get_Value): When copying the component default expression for a
10320 defaulted association in an aggregate, use the sloc of the aggregate
10321 and not that of the original expression, to prevent spurious
10322 elaboration errors, when the expression includes function calls.
10323 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
10324 were missing. We also didn't handle qualified expressions. Now also
10325 allow function calls. Use new common routine OK_For_Limited_Init.
10326 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
10327 with space can upper case letter).
10329 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
10330 Has_Static_Discriminants flag
10331 (Record_Type_Declaration): Diagnose an attempt to declare an interface
10332 type with discriminants.
10333 (Process_Range_Expr_In_Decl): Do validity checks on range
10334 (Build_Discriminant_Constraints): Use updated form of
10335 Denotes_Discriminant.
10336 (Process_Subtype): If the subtype is a private subtype whose full view
10337 is a concurrent subtype, introduce an itype reference to prevent scope
10339 (Build_Derived_Record_Type, Collect_Interface_Primitives,
10340 Record_Type_Declaration): The functionality of the subprograms
10341 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
10342 is now performed by a single routine.
10343 (Build_Derived_Record_Type): If the type definition includes an explicit
10344 indication of limitedness, then the type must be marked as limited here
10345 to ensure that any access discriminants will not be treated as having
10346 a local anonymous access type.
10347 (Check_Abstract_Overriding): Issue a detailed error message when an
10348 abstract subprogram was not overridden due to incorrect mode of its
10350 (Analyze_Private_Extension_Declaration): Add support for the analysis of
10351 synchronized private extension declarations. Verify that the ancestor is
10352 a limited or synchronized interface or in the generic case, the ancestor
10353 is a tagged limited type or synchronized interface and all progenitors
10354 are either limited or synchronized interfaces.
10355 Derived_Type_Declaration): Check for presence of private extension when
10356 dealing with synchronized formal derived types.
10357 Process_Full_View): Enchance the check done on the usage of "limited" by
10358 testing whether the private view is synchronized.
10359 Verify that a synchronized private view is completed by a protected or
10361 (OK_For_Limited_Init_In_05): New function.
10362 (Analyze_Object_Declaration): Move check for limited types later,
10363 because OK_For_Limited_Init requires its argument to have been resolved.
10364 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10365 in order to alleviate the upward compatibility introduced by AI-318.
10366 (Constrain_Corresponding_Record): If the constraint is for a component
10367 subtype, mark the itype as frozen, to avoid out-of-scope references to
10368 discriminants in the back-end.
10369 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
10370 this subprogram against wrong sources.
10371 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
10372 discriminant of limited type completed with a protected type, when the
10373 discriminant is used to constrain a private component of the type, and
10374 expansion is disabled.
10375 (Find_Type_Of_Object): Do not treat a return subtype that is an
10376 anonymous subtype as a local_anonymous_type, because its accessibility
10377 level is the return type of the enclosing function.
10378 (Check_Initialization): In -gnatg mode, turn the error "cannot
10379 initialize entities of limited type" into a warning.
10380 (OK_For_Limited_Init): Return true for generated nodes, since it
10381 sometimes violates the legality rules.
10382 (Make_Incomplete_Declaration): If the type for which an incomplete
10383 declaration is created happens to be the currently visible entity,
10384 preserve the homonym chain when removing it from visibility.
10385 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
10386 inherited subprograms.
10387 (Access_Definition): If this is an access to function that is the return
10388 type of an access_to_function definition, context is a type declaration
10389 and the scope of the anonymous type is the current one.
10390 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
10391 incomplete subtype to the set of private dependents of the original
10393 (Constrain_Discriminated_Type): Emit an error message whenever an
10394 incomplete subtype is being constrained.
10395 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
10396 corresponding subtype of the full view of the original incomplete type.
10397 (Check_Incomplete): Properly detect invalid usage of incomplete types
10400 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
10402 * g-catiio.ads, g-catiio.adb (Value): New function.

10411 Robert Dewar <dewar@adacore.com>
10413 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
10414 handling executable extension manually and duplicating code.
10416 * make.adb: Implement new -S switch
10417 (Gnatmake): Use new function Osint.Executable_Name instead
10418 of handling executable extension manually.
10420 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
10421 is specified, the executable name ends with this suffix.
10422 Take advantage of Osint.Executable_Name instead of duplicating code.
10424 * switch-m.adb: Recognize new gnatmake -S switch
10426 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
10428 (Get_Target_Parameters): Set Executable_Extension_On_Target if
10431 * makeusg.adb: Add line for gnatmake -S switch
10433 2006-10-31 Vincent Celier <celier@adacore.com>
10435 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
10436 call it with -static-libgcc, as there are some platforms, such as
10437 Darwin, where one of these two switches is compulsory to link.
10439 2006-10-31 Vincent Celier <celier@adacore.com>
10441 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
10442 instead of ADA_PROJECT_PATH, for the project path.
10443 (Gnatls): When displaying the project path directories, use host dir
10446 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
10447 names in the project path, as absolute paths may correspond to
10448 multi-valued VMS logical names.
10450 2006-10-31 Vincent Celier <celier@adacore.com>
10452 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
10453 absolute path name.
10454 (Locate_Regular_File): Ditto
10455 (Change_Dir): Remove, no longer used
10456 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
10457 on Windows. Get it calling Get_Current_Dir.

10465 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
10467 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
10470 2006-10-31 Robert Dewar <dewar@adacore.com>
10472 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
10473 initial letter o as a zero.

10477 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
10479 2006-10-31 Robert Dewar <dewar@adacore.com>
10481 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
10483 (Layout_Variant_Record): Retrieve the discriminants from the entity
10484 rather than from the type definition, because in the case of a full
10485 type for a private type we need to take the discriminants from the
10487 (Layout_Component_List): When applying the Max operator to variants with
10488 a nonstatic size, check whether either operand is static and scale that
10489 operand from bits to storage units before applying Max.
10490 (Layout_Type): In VMS, if a C-convention access type has no explicit
10491 size clause (and does not inherit one in the case of a derived type),
10492 then the size is reset to 32 from 64.
10494 2006-10-31 Vincent Celier <celier@adacore.com>
10496 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
10497 its file has already been loaded, according to the unit being loaded,
10498 not to the current value of Multiple_Unit_Index.
10500 2006-10-31 Thomas Quinot <quinot@adacore.com>
10501 Eric Botcazou <ebotcazou@adacore.com>
10502 Arnaud Charlet <charlet@adacore.com>
10504 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
10505 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
10507 (a-except.o): Pass it to the compiler.
10508 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.

10515 Ada.Dispatching.Round_Robin.
10516 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
10518 * Make-lang.in: Remove all references to gt-ada-decl.h.
10519 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
10521 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
10522 Update dependencies.
10524 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
10526 2006-10-31 Vincent Celier <celier@adacore.com>
10528 * mlib-utl.adb (Initialized): Remove, no longer used
10529 (Initialize): Remove, no longer used
10530 (Ar): If Ar_Exec is null, get the location of the archive builder and,
10531 if there is one, the archive indexer. Fail if the archive builder cannot
10533 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
10536 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10538 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
10539 Process_Body_Clauses): If the context of a body includes a use clause
10540 for P.Q then a with_clause for P in the same body is not redundant,
10541 even if the spec also has a with_clause on P.
10542 Add missing continuation mark to error msg
10543 (Build_Limited_Views): A limited view of a type is tagged if its
10544 declaration includes a record extension.
10545 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
10546 node, even if the subunit has errors. This avoids malfunction by
10547 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
10548 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
10549 generation of obsolescent messages for with statements (cannot do
10550 this too early, or we cannot implement avoiding the messages in the
10551 case of obsolescent units withing obsolescent units).
10552 (Install_Siblings): If the with_clause is on a remote descendant of
10553 an ancestor of the current compilation unit, find whether there is
10554 a sibling child unit that is immediately visible.
10555 (Remove_Private_With_Clauses): New procedure, invoked after completing
10556 the analysis of the private part of a nested package, to remove from
10557 visibility the private with_clauses of the enclosing package
10559 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
10560 now centralized in Generate_Reference.
10561 (Install_Limited_Context_Clauses): Remove superfluous error
10562 message associated with unlimited view visible through use
10563 and renamings. In addition, at the point in which the error
10564 is reported, we add the backslash to the text of the error
10565 to ensure that it is reported as a single error message.
10566 Use new // insertion for some continuation messages
10567 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
10568 to create implicit with_clause for parent unit mentioned in original
10569 limited_with_clause.
10570 (Install_Limited_With_Unit): Set entity of parent identifiers if the
10571 unit is a child unit. For ASIS queries.
10572 (Analyze_Subunit): If the subunit appears within a child unit, make all
10573 ancestor child units directly visible again.
10575 2006-10-31 Robert Dewar <dewar@adacore.com>

10585 Add the new actual Abstract_Present to every call to
10586 P_Interface_Type_Definition.
10587 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
10588 a formal object declaration with an access definition or a subtype mark
10589 with a null exclusion.
10590 (P_Generic_Association): Handle association with box, and others_choice
10591 with box, to support Ada 2005 partially parametrized formal packages.
10593 2006-10-31 Robert Dewar <dewar@adacore.com>
10594 Javier Miranda <miranda@adacore.com>
10596 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
10597 (P_Type_Declaration): Remove barrier against the reserved word "limited"
10598 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
10599 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
10600 private extensions.
10601 (P_Type_Declaration): Add the new actual Abstract_Present to every call
10602 to P_Interface_Type_Definition.
10603 (P_Interface_Type_Definition): Addition of one formal to report an error
10604 if the reserved word abstract has been previously found.
10605 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
10606 object renaming declaration with an access definition or subtype mark
10607 with a possible null exclusion.
10609 * par-ch9.adb: Minor error msg fix
10611 * par-load.adb: Add missing continuation mark to error msg
10613 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation

10617 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
10618 unknown attribute in unknown package or in package that does not need
10620 (Parse_Package_Declaration): Do not issue warning for unknown package in
10623 2006-10-31 Vincent Celier <celier@adacore.com>
10625 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
10626 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
10629 2006-10-31 Vincent Celier <celier@adacore.com>
10631 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
10632 on VMS, change "__" to '.' before checking the name.
10633 (Record_Ada_Source): Always add the source file name in the list of
10634 of sources, even if it is not the first time, as it is for another
10636 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
10637 dot, instead of replacing only the first '_'.
10639 * prj-part.adb (Parse): Convert project file path to canonical form
10641 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
10642 extended, the project id of the project extending it is recorded in its
10643 data, even when it has already been processed as an imported project.
10645 2006-10-31 Robert Dewar <dewar@adacore.com>
10647 * repinfo.adb (List_Entities): Don't list entities from renaming
10650 2006-10-31 Arnaud Charlet <charlet@adacore.com>
10651 Robert Dewar <dewar@adacore.com>
10653 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
10654 only a restriction warning is active for the given restriction. This is
10655 desirable because we do not want to modify code in the case where only
10657 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
10658 causes overriding of real restrictions.
10659 Take advantage of new No_Restrictions constant.
10661 * raise.h: (__gnat_set_globals): Change profile.
10663 2006-10-31 Arnaud Charlet <charlet@adacore.com>
10665 * rtsfind.adb: Remove s-polint from comment as it exists no more.
10668 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
10669 Move all the entities in obsolete package System.PolyORB_Interface to
10670 System.Partition_Interface.
10671 (RE_Storage_Size): New function in System.Tasking.
10672 (RE_Get_Ceiling): New entity.

10684 Thomas Quinot <quinot@adacore.com>
10685 Javier Miranda <miranda@adacore.com>
10686 Gary Dismukes <dismukes@adacore.com>
10688 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
10689 properly an attempt to apply Unchecked_Access to a protected operation.
10690 (OK_Self_Reference): New subprogram to check the legality of an access
10691 attribute whose prefix is the type of an enclosing aggregate.
10692 Generalizes previous mechanism to handle attribute references nested
10693 arbitrarily deep within the aggregate.
10694 (Analyze_Access_Attribute): An access attribute whose prefix is a type
10695 can appear in an aggregate if this is a default-initialized aggregate
10696 for a self-referential type.
10697 (Resolve_Attribute, case Access): Ditto.
10698 Add support for new implementation defined attribute Stub_Type.
10699 (Eval_Attribute, case Attribute_Stub_Type): New case.
10700 (Analyze_Attribute, case Attribute_Stub_Type): New case.
10701 (Stream_Attribute_Available): Implement using new subprogram from
10702 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
10703 Has_Specified_Stream_Attribute flag.
10704 Disallow Storage_Size and Storage_Pool for access to subprogram
10705 (Resolve_Attribute, case 'Access et al): Take into account anonymous
10706 access types of return subtypes in extended return statements. Remove
10707 accessibility checks on anonymous access types when Unchecked_Access is
10709 (Analyze_Attribute): Add support for the use of 'Class to convert
10710 a class-wide interface to a tagged type.
10711 Add support for the attribute Priority.
10712 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
10713 whether the designated type is discriminated with a constrained partial
10714 view and require static matching in that case.
10715 Add local variable Des_Btyp. The Designated_Type
10716 of an access to incomplete subtype is either its non-limited view if
10717 coming from a limited with or its etype if regular incomplete subtype.
10719 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
10720 Fix predicate to identify and allow cases of (expander-generated)
10721 references to tag of designated object of a RACW.
10722 (Validate_Static_Object_Name): In Ada 2005, a formal object is
10723 non-static, and therefore cannot appear as a primary in a preelaborable
10725 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
10726 Has_Read_Write_Attributes.
10727 (Has_Read_Write_Attributes): Reimplement in termes of
10728 Has_Stream_Attribute_Definition.
10729 (Missing_Read_Write_Attributes): When checking component types in a
10730 record, unconditionally call Missing_Read_Write_Attributes recursively
10731 (remove guard checking for Is_Record_Type / Is_Access_Type).
10733 2006-10-31 Robert Dewar <dewar@adacore.com>
10735 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
10736 useless assignments here and conditionalize it on absence of exception
10738 (Analyze_Exception_Handlers): Small code reorganization of error
10739 detection code, for new handling of formal packages.
10741 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10742 Hristian Kirtchev <kirtchev@adacore.com>
10744 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
10745 that has been constant-folded, preserve information of original tree,
10747 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
10748 generated private extension declaration if the formal derived type is
10749 synchronized. Carry synchronized present over to the generated private
10751 (Validate_Derived_Type_Instance): Ensure that the actual of a
10752 synchronized formal derived type is a synchronized tagged type.
10753 (Instantiate_Formal_Package): When creating the instantiation used to
10754 validate the actual package of a formal declared without a box, check
10755 whether the formal itself depends on a prior actual.
10756 (Instantiate_Formal_Subprogram): Create new entities for the defining
10757 identifiers of the formals in the renaming declaration, for ASIS use.
10758 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
10759 a renaming declaration or a subtype declaration for an actual in an
10760 instance, capture location information of declaration in generic, for
10762 (Instantiate_Formal_Package): Add comments on needed additional tests.
10763 AI-317 (partial parametrization) is fully implemented.
10764 (Validate_Private_Type_Instance): Add check for actual which
10765 must have preelaborable initialization
10766 Use new // insertion for some continuation messages
10767 (Analyze_Formal_Object_Declaration): Change usage of Expression to
10768 Default_Expression. Add type retrieval when the declaration has an
10769 access definition. Update premature usage of incomplete type check.
10770 (Check_Access_Definition): New subsidiary routine. Check whether the
10771 current compilation version is Ada 05 and the supplied node has an
10773 (Instantiate object): Alphabetize local variables. Handle the creation
10774 of new renaming declarations with respect to the kind of definition
10775 used - either an access definition or a subtype mark. Guard against
10776 unnecessary error message in the context of anonymous access types after
10777 they have been resolved. Add check for required null exclusion in a
10778 formal object declaration.
10779 (Switch_View): A private subtype of a non-private type needs to be
10780 switched (the base type can have been switched without its private
10781 dependents because of the last branch of Check_Private_View.
10782 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
10784 (Instantiate_Type): Emit an error message whenever a class-wide type of
10785 a tagged incomplete type is used as a generic actual.
10786 (Find_Actual_Type): Extend routine to handle a component type in a child
10787 unit that is imported from a formal package in a parent.
10788 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
10789 agree on constrainedness, rather than checking against ultimate ancestor
10790 (Instantiate_Subprogram_Body): Create a cross-reference link to the
10791 generic body, for navigation purposes.
10793 2006-10-31 Robert Dewar <dewar@adacore.com>
10794 Thomas Quinot <quinot@adacore.com>
10796 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
10798 (New_Stream_Subprogram): When processing an attribute definition clause
10799 for a stream-oriented subprogram, record an entity node occurring at
10800 the point of clause to use for checking the visibility of the clause,
10801 as defined by 8.3(23) as amended by AI-195.
10802 (New_Stream_Subprogram): New procedure, factoring behaviour from both
10803 New_Stream_Function and New_Stream_Procedure.
10804 (New_Stream_Function, New_Stream_Procedure): Removed.
10805 (Analyze_Attribute_Definition_Clause, case Address): Check new
10806 Alignment_Check check
10808 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10809 Javier Miranda <miranda@adacore.com>
10810 Robert Dewar <dewar@adacore.com>
10812 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
10813 generate the same errors compiling under -gnatc.
10814 (Try_Object_Operation): If no candidate interpretation succeeds, but
10815 there is at least one primitive operation with the right name, report
10816 error in call rather than on a malformed selected component.
10817 (Analyze_Selected_Component): If the prefix is an incomplete type from
10818 a limited view, and the full view is available, use the full view to
10819 determine whether this is a prefixed call to a primitive operation.
10820 (Operator_Check): Verify that a candidate interpretation is a binary
10821 operation before checking the type of its second formal.
10822 (Analyze_Call): Add additional warnings for function call contexts not
10824 (Analyze_Allocator): Move the check for "initialization not allowed for
10825 limited types" after analyzing the expression. This is necessary,
10826 because OK_For_Limited_Init looks at the structure of the expression.
10827 Before analysis, we don't necessarily know what sort of expression it
10828 is. For example, we don't know whether F(X) is a function call or an
10829 indexed component; the former is legal in Ada 2005; the latter is not.
10830 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
10831 were missing. We also didn't handle qualified expressions. Now also
10832 allow function calls. Use new common routine OK_For_Limited_Init.
10833 (Analyze_Type_Conversion): Do not perform some legality checks in an
10834 instance, because the error message will be redundant or spurious.
10835 (Analyze_Overloaded_Selected_Component): Do not do style check when
10836 setting an entity, since we do not know it is the right entity yet.
10837 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
10838 (Analyze_Overloaded_Selected_Component): Same change
10839 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
10840 since regular incomplete subtypes are transformed into corresponding
10841 subtypes of their full views.
10842 (Complete_Object_Operation): Treat name of transformed subprogram call
10843 as coming from source, for browsing purposes.
10844 (Try_Primitive_Operation): If formal is an access parameter, compare
10845 with base type of object to determine whether it is a primitive
10847 (Operator_Check): If no interpretation of the operator matches, check
10848 whether a use clause on any candidate might make the operation legal.
10849 (Try_Class_Wide_Operation): Check whether the first parameter is an
10850 access type whose designated type is class-wide.

10853 Ed Schonberg <schonberg@adacore.com>
10854 Gary Dismukes <dismukes@adacore.com>
10856 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
10857 warn on infinite loops.
10858 Add \\ to some continuation messages
10859 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
10860 (Process_Bounds): If the bounds are integer literals that result from
10861 constant-folding, and they carry a user-defined type, preserve that type
10862 rather than treating this as an integer range.
10863 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
10864 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
10865 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
10866 left hand side of assignment.
10867 (Analyze_Assignment): Add suport to manage assigments to the attribute
10868 priority of a protected object.
10869 (Check_Possible_Current_Value_Condition): Allow fully qualified names
10870 not just identifiers.
10871 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
10872 or AND THEN for possible tracking.
10873 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
10874 case of while loops so we can track values in the loop body.
10876 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10877 Hristian Kirtchev <kirtchev@adacore.com>
10878 Bob Duff <duff@adacore.com>
10880 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
10881 procedure cannot be a protected operation (it is a basic_declaration,
10882 not a subprogram_declaration).
10883 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
10884 Subp. Add logic for entry processing.
10885 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
10886 Determine whether an entry or subprogram of a protected or task type
10887 override an inherited primitive of an implemented interface.
10888 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
10889 Update the actual used in calls to Check_Overriding_Indicator.
10890 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
10891 generate the proper reference to the parent unit, for cross-reference.
10892 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
10894 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10895 (Add_Extra_Formal): Revise procedure to allow passing in associated
10896 entity, scope, and name suffix, and handle setting of the new
10897 Extra_Formals field.
10898 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
10899 pass new parameters. Add support for adding the new extra access formal
10900 for functions whose calls are treated as build-in-place.
10901 (Analyze_A_Return_Statement): Correct casing in error message.
10902 Move Pop_Scope to after Analyze_Function_Return, because an extended
10903 return statement really is a full-fledged scope. Otherwise, visibility
10904 doesn't work right. Correct use of "\" for continuation messages.
10905 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
10906 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
10907 the node doesn't get properly marked as analyzed.
10908 (Analyze_Subprogram_Body): If subprogram is a function that returns
10909 an anonymous access type that denotes a task, build a Master Entity

10941 we are in its visible part.
10942 (Declare_Inherited_Private_Subprograms): Complete barrier
10943 to ensure that the primitive operation has an alias to some parent
10944 primitive. This is now required because, after the changes done for the

10947 such list of primitives.
10948 (Analyze_Package_Specification): Simplify code that handles parent units
10949 of instances and formal packages.

10965 as potentially use-visible.
10966 (Find_Type): Handle the case of an attribute reference for
10967 implementation defined attribute Stub_Type (simply let the analysis of

10994 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
10995 Check_Overriding_Indicator.
10996 (Analyze_Task_Definition): Ditto.
10997 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
10998 (Check_Overriding_Indicator): To find overridden interface operation,
10999 examine only homonyms that have an explicit subprogram declaration, not
11000 inherited operations created by an unrelated type derivation.

11020 of a call to a function that dispatches on access result.
11021 (Check_Dispatching_Operation): In case of late overriding of a primitive
11022 that covers abstract interface subprograms we register it in all the
11023 secondary dispatch tables associated with abstract interfaces.
11024 (Check_Dispatching_Call): Add check that a dispatching call is not made
11025 to a function with a controlling result of a limited type. This is a
11026 current implementation restriction.
11027 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).

11076 ought to be used, but we currently only deal properly with zero or one
11078 (In_Instance); The analysis of the actuals in the instantiation of a
11079 child unit is not within an instantiation, even though the parent
11080 instance is on the scope stack.

11083 (Check_Obsolescent): Removed
11084 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

11339 This is a significant redesign primarily for the sake of automatic
11340 timer task termination but also to fix a design flaw.
11341 Therefore we are now using an RTS lock, instead of a protected
11342 object, to provide mutual exclusion to the queue of pending events
11343 and the type Timing_Event is no longer a protected type.

12191 other basic tools. The full version that includes the Ada 2005 stuff
12192 is in separate files a-except-2005.ads/adb. The reason is that we do
12193 not want to cause bootstrap problems with compilers not recognizing
12195 Add exception reason code PE_Implicit_Return

12518 positive. Also add checks against invalid values, and support for kb,
12519 mb. Ditto for -D switch.

12522 Serguei Rybin <rybin@adacore.com>
12524 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
12525 save/restore routines.
12526 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

12528 Since we are changing the tree format anyway, also get rid of the
12529 junk obsolete Immediate_Errors flag.
12530 (Tree_Read): Change the way of reading Tree_Version_String - now we
12531 read the version string from the tree even if its length is not the
12532 same as the length of the version string computed from Gnatvsn.
12533 (Search_Directory_Present): New Boolean flag for the compiler.
12534 Define Tree_Version_String as a dynamic string.

12559 (Is_Limited_Type): A type whose ancestor is an interface is limited if
12560 explicitly declared limited.
12561 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
12562 entities. Only used for component marked Is_Tag. If present it stores
12563 the Offset_To_Top function used to provide this value in tagged types
12564 whose ancestor has discriminants.
12566 * exp_ch2.adb: Update status of new Is_Known_Null flag
12568 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

12587 (__gl_default_stack_size): new variable.
12589 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12591 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
12592 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
12593 does not exist in the Ada RM.
12594 (Compatible_Int_Bounds): Determine whether two integer range bounds
12595 are of equal length and have the same start and end values.
12596 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
12597 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
12598 aggregate when it is part of an object declaration.
12599 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
12600 constrains discriminants of its parent, add explicitly the discriminant
12601 constraints of the ancestor by retrieving them from the
12602 stored_constraint of the parent.
12604 2006-02-13 Robert Dewar <dewar@adacore.com>
12606 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
12607 attribute Mechanism_Code is applied to renamed subprogram, modify
12608 prefix to point to base subprogram.
12609 Max/Min attributes now violate Restriction No_Implicit_Conditionals
12611 * sinfo.ads: Document that Mechanism_Code cannot be applied to
12612 renamed subprograms so that the front-end must replace the prefix

12616 Gary Dismukes <dismukes@adacore.com>
12618 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
12619 availability of RE_Interface_Tag.
12620 (Build_Initialization_Call): Fix wrong access to the discriminant value.
12621 (Freeze_Record_Type): Do not generate the tables associated with
12622 timed and conditional dispatching calls through synchronized
12623 interfaces if compiling under No_Dispatching_Calls restriction.
12624 When compiling for Ada 2005, for a nonabstract
12625 type with a null extension, call Make_Controlling_Function_Wrappers
12626 and insert the wrapper function declarations and bodies (the latter
12627 being appended as freeze actions).
12628 (Predefined_Primitive_Bodies): Do not generate the bodies of the
12629 predefined primitives associated with timed and conditional
12630 dispatching calls through synchronized interfaces if we are
12631 compiling under No_Dispatching_Calls.
12632 (Build_Init_Procedure): Use RTE_Available to check if a run-time
12633 service is available before generating a call.
12634 (Make_Controlling_Function_Wrappers): New procedure.
12635 (Expand_N_Full_Type_Declaration): Create a class-wide master for
12636 access-to-limited-interfaces because they can be used to reference
12637 tasks that implement such limited interface.
12638 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
12639 procedure spec and body of the Offset_To_Top function that is generated
12640 when the parent of a type with discriminants has secondary dispatch
12642 (Init_Secondary_Tags): Handle the case in which the parent of the type
12643 containing secondary dispatch tables has discriminants to generate the
12644 correct arguments to call Set_Offset_To_Top.
12645 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
12647 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
12648 Add Wide_[Wide_]Expanded_Name.
12649 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
12650 the same functionality of Get_Prim_Op_Address but applied to predefined
12651 primitive operations because the pointers to the predefined primitives
12652 are now saved in a separate table.
12653 (Parent_Size): Modified to get access to the separate table of primitive
12654 operations or the parent type.
12655 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
12656 functionality of Set_Prim_Op_Address but applied to predefined primitive
12658 (Set_Signature): New subprogram used to store the signature of a DT.
12659 (Displace): If the Offset_To_Top value is not static then call the
12660 function generated by the expander to get such value; otherwise use
12661 the value stored in the table of interfaces.
12662 (Offset_To_Top): The type of the actual has been changed to Address to
12663 give the correct support to tagged types with discriminants. In this
12664 case this value is stored just immediately after the tag field.
12665 (Set_Offset_To_Top): Two new formals have been added to indicate if the
12666 offset_to_top value is static and hence pass this value to the run-time
12667 to store it in the table of interfaces, or else if this value is dynamic
12668 and then pass to the run-time the address of a function that is
12669 generated by the expander to provide this value for each object of the
12672 * rtsfind.ads (Default_Prin_Op_Count): Removed.
12673 (Default_Prim_Op_Count): New entity
12674 (Get_Predefined_Prim_Op_Address): New entity

12679 Ed Schonberg <schonberg@adacore.com>
12681 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
12682 Make_Adjust_Call done for a newly-allocated object.
12684 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
12685 in a subprogram are wrapped in a cleanup block, indicate that the
12686 subprogram contains an inner block with an exception handler.
12687 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
12688 Adjust call is for a newly-allocated object. In that case we must not
12689 assume that the finalization list chain pointers are correct (since they
12690 come from a bit-for-bit copy of the original object's pointers) so if
12691 the attach level would otherwise be zero (no change), we set it to 4
12692 instead to cause the pointers to be reset to null.
12694 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
12695 reset chain pointers to null.
12697 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12699 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
12700 string, and the context requires a loop for the assignment (e.g.
12701 because the left-hand side is packed), generate a unique name for the
12702 temporary that holds the string, to prevent spurious name clashes.
12704 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12705 Javier Miranda <miranda@adacore.com>
12706 Robert Dewar <dewar@adacore.com>
12707 Gary Dismukes <dismukes@adacore.com>
12709 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
12710 return unconstrained arrays.
12712 (Expand_Call): An indirect call through an access parameter of a
12713 protected operation is not a protected call.
12714 Add circuit to raise CE in Ada 2005 mode following call
12715 to Raise_Exception.
12716 (Register_DT_Entry): Do nothing if
12717 the run-time does not give support to abstract interfaces.
12718 (Freeze_Subprogram): In case of dispatching operations, do not generate
12719 code to register the operation in the dispatch table if the source
12720 is compiled with No_Dispatching_Calls.
12721 (Register_Predefined_DT_Entry): Generate code that calls the new
12722 run-time subprogram Set_Predefined_Prim_Op_Address instead of
12723 Set_Prim_Op_Address.
12725 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
12726 on array assignments if the right-hand side is a function call that has
12727 been inlined. Check is performed on the assignment in the block.
12728 (Process_Bounds): If bounds and range are overloaded, apply preference
12729 rule for root operations to disambiguate, and diagnose true ambiguity.
12730 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
12731 a tag-indeterminate right-hand side even when Expander_Active is True.
12732 Needed to ensure that dispatching calls to T'Input are allowed and
12733 get the tag of the target class-wide object.
12735 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
12736 an inherited primitive operation that already overrides several
12737 abstract interface primitives. For transitivity, the new entity must
12738 also override all the abstract interface primitives covered by the
12739 inherited overriden primitive.
12740 Emit warning if new entity differs from homograph in same scope only in
12741 that one has an access parameter and the other one has a parameter of
12742 a general access type with the same designated type, at the same
12743 position in the signature.
12744 (Make_Inequality_Operator): Use source locations of parameters and
12745 subtype marks from corresponding equality operator when creating the
12746 tree structure for the implicit declaration of "/=". This does not
12747 change anything in behaviour except that the decoration of the
12748 components of the subtree created for "/=" allows ASIS to get the
12749 string images of the corresponding identifiers.
12750 (Analyze_Return_Statement): Remove '!' in warning message.
12751 (Check_Statement_Sequence): Likewise.
12752 (Analyze_Subprogram_Body): For an access parameter whose designated type
12753 is an incomplete type imported through a limited_with clause, use the
12754 type of the corresponding formal in the body.
12755 (Check_Returns): Implicit return in No_Return procedure now raises
12756 Program_Error with a compile time warning, instead of beging illegal.
12757 (Has_Single_Return): Function returning unconstrained type cannot be
12758 inlined if expression in unique return statement is not an identifier.
12759 (Build_Body_To_Inline): It is possible to inline a function call that
12760 returns an unconstrained type if all return statements in the function
12761 return the same local variable. Subsidiary procedure Has_Single_Return
12762 verifies that the body conforms to this restriction.
12764 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
12765 same type, and one of them is of an anonymous access type, convert
12766 the other operand to it, so that this is a valid binary operation for
12768 (Resolve_Type_Conversion): Handle subtypes of protected types and
12769 task types when accessing to the corresponding record type.
12770 (Resolve_Allocator): Add '\' in 2-line warning message.
12771 Remove '!' in warning message.
12772 (Resolve_Call): Add '\' in 2-line warning message.
12773 (Valid_Conversion): Likewise.
12774 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
12775 resulting type may be an access type with an implicit dereference.
12776 Obtain the proper component from the designated type.
12777 (Make_Call_Into_Operator): Handle properly a call to predefined equality
12778 given by an expanded name with prefix Standard, when the operands are
12779 of an anonymous access type.
12780 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
12781 Explicit_Dereference and Resolve_Selected_Component, to verify that the
12782 prefix of the expression is not of an incomplete type. Allows full
12783 diagnoses of all semantic errors.
12784 (Resolve_Actuals): If the actual is an allocator whose directly
12785 designated type is a class-wide interface we build an anonymous
12786 access type to use it as the type of the allocator. Later, when
12787 the subprogram call is expanded, if the interface has a secondary
12788 dispatch table the expander will add a type conversion to force
12789 the displacement of the pointer.
12790 (Resolve_Call): If a function that returns an unconstrained type is
12791 marked Inlined_Always and inlined, the call will be inlined and does
12792 not require the creation of a transient scope.
12793 (Check_Direct_Boolean_Op): Removed
12794 (Resolve_Comparison_Op): Remove call to above
12795 (Resolve_Equality_Op): Remove call to above
12796 (Resolve_Logical_Op): Inline above, since this is only call.
12797 (Valid_Conversion): Handle properly conversions between arrays of
12798 convertible anonymous access types.
12801 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
12802 the literal in an unchecked conversion, because GCC 4.x needs a static
12803 value for a string bound.

12806 Hristian Kirtchev <kirtchev@adacore.com>
12808 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
12809 components of the corresponding record, take into account component
12810 definitions that are access definitions.
12811 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
12812 procedure is not considered a dispatching call and will be expanded
12815 2006-02-13 Javier Miranda <miranda@adacore.com>
12817 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
12818 controlling argument of the dispatching call is an abstract interface
12819 class-wide type then we use it directly.
12820 Check No_Dispatching_Calls restriction.
12821 (Default_Prim_Op_Position): Remove the code that looks for the last
12822 entity in the list of aliased subprograms. This code was wrong in
12824 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
12825 when the source is compiled with the No_Dispatching_Calls restriction.
12826 (Init_Predefined_Interface_Primitives): No need to inherit primitives
12827 if we are compiling with restriction No_Dispatching_Calls.
12828 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
12829 subprograms if we are compiling under No_Dispatching_Calls restriction.
12830 (Make_DT): Generate a dispatch table with a single dummy entry if
12831 we are compiling with the No_Dispatching_Calls restriction. In
12832 addition, in this case we don't generate code that calls to the
12833 following run-time subprograms: Set_Type_Kind, Inherit_DT.
12834 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
12835 of this subprogram if compiling with the No_Dispatching_Calls
12837 (Expand_Type_Conversion): Instead of using the actual parameter,
12838 the argument passed as parameter to the conversion function was
12839 erroneously referenced by the expander.
12840 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
12841 Set_Predefined_Primitive_Op_Address and Set_Signature.
12842 (Expand_Dispatching_Call): Generate call to
12843 Get_Predefined_Prim_Op_Address for predefined primitives.
12844 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
12845 predefined primitives.
12846 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
12847 primitives we reserve one dummy entry to ensure that the tag does not
12848 point to some memory that is associated with some other object. In
12849 addition, remove all the old code that generated the assignments
12850 associated with the signature of the dispatch table and replace them
12851 by a call to the new subprogram Set_Signature.
12852 (Set_All_DT_Position): Change the algorithm because now we have a
12853 separate dispatch table associated with predefined primitive operations.
12854 (Expand_Interface_Conversion): In case of non-static offset_to_top
12855 add explicit dereference to get access to the object after the call
12856 to displace the pointer to the object.
12857 (Expand_Interface_Thunk): Modify the generation of the actual used
12858 in the calls to the run-time function Offset_To_Top to fulfil its
12860 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

12864 * exp_dist.adb (Copy_Specification): For access parameters, copy
12865 Null_Exclusion flag, which will have been set for stream subprograms
12868 2006-02-13 Pascal Obry <obry@adacore.com>
12870 * expect.c (__gnat_expect_portable_execvp): New implementation. The
12871 previous implementation was using the C runtime spawnve routine but
12872 the corresponding wait was using directly the Win32 API. This was
12873 causing some times a lock when waiting for an event using
12874 WaitForSingleObject in __gnat_waitpid. This new implementation uses
12875 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
12876 API fixes this problem.
12878 2006-02-13 Robert Dewar <dewar@adacore.com>
12880 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

12887 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
12888 array reference that is an explicit dereference, mark the converted
12889 (packed) array reference as analyzed to prevent a forthcoming
12890 reanalysis from resetting its type to the original (non-packed) array
12893 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12894 Javier Miranda <miranda@adacore.com>
12895 Eric Botcazou <ebotcazou@adacore.com>
12897 * exp_util.ads, exp_util.adb (Find_Prim_Op,
12898 Is_Predefined_Primitive_Operation): When
12899 searching for the predefined equality operator, verify that operands
12900 have the same type.
12901 (Is_Predefined_Dispatching_Operation): Remove the code that looks
12902 for the last entity in the list of aliased subprograms. This code
12903 was wrong in case of renamings.
12904 (Set_Renamed_Subprogram): New procedure
12905 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
12906 Exp_Type constant computed when entering this subprogram.
12907 (Known_Null): New function
12908 (OK_To_Do_Constant_Replacement): New function
12909 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
12910 (Side_Effect_Free): An attribute reference 'Input is not free of
12911 side effect, unlike other attributes that are functions. (from code
12913 (Remove_Side_Effects): Expressions that involve packed arrays or records
12914 are copied at the point of reference, and therefore must be marked as
12915 renamings of objects.
12916 (Is_Predefined_Dispatching_Operation): Return false if the operation is
12917 not a dispatching operation.
12920 (Remove_Side_Effects): Lift enclosing type conversion nodes for
12921 elementary types in all cases.
12923 2006-02-13 Javier Miranda <miranda@adacore.com>

12926 task types when accessing to the corresponding record type.
12927 Remove '!' in warning message.
12929 2006-02-13 Olivier Hainque <hainque@adacore.com>
12931 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
12932 to avoid useless and space inefficient overalignments on targets where
12933 Max_Alignment is larger than 16.
12935 2006-02-13 Pascal Obry <obry@adacore.com>
12937 * g-catiio.adb (Sec_Number): New type used to compute the number of
12938 seconds since 1-1-1970.
12939 (Image) [Natural]: The parameter was an Integer, as we can't deal with
12940 negative numbers (years, months...) it is better to have a Natural here.
12942 (Image) [Number]: Change parameter from Long_Integer to Number.
12943 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
12944 overflow for dates past year 2038.
12946 2006-02-13 Matthew Heaney <heaney@adacore.com>
12948 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
12951 2006-02-13 Arnaud Charlet <charlet@adacore.com>
12953 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
12955 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
12956 finalization can occur normally.
12958 2006-02-13 Vincent Celier <celier@adacore.com>
12960 * gnatcmd.adb (Rules_Switches): New table
12961 (Add_To_Rules_Switches): New procedure
12962 (GNATCmd): For command CHECK, put all options following "-rules" in the
12963 Rules_Switches table. Append these -rules switches after the -cargs
12966 2006-02-13 Robert Dewar <dewar@adacore.com>
12968 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
12969 These two cases were generating incorrect output, and if this unit
12970 was built with checks on, generated a discriminant mismatch constraint
12973 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12974 Robert Dewar <dewar@adacore.com>
12976 * lib-xref.adb (Get_Type_Reference): For a private type whose full
12977 view is an array type, indicate the component type as well, for
12978 navigation purposes.
12979 (Generate_Reference): Don't consider array ref on LHS to be a case
12980 of violating pragma Unreferenced.
12981 Do not give Ada 2005 warning except on real reference.
12983 2006-02-13 Vincent Celier <celier@adacore.com>
12985 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
12986 main source, add switch -mdebug-main=_ada_ so that the executable can
12987 be debugged by the standard VMS debugger.
12988 (Gnatmake): Set No_Main_Subprogram to True when there is no main
12989 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
12990 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
12991 of the last source, as the binding and linking phases are never
12993 Set all executable obsolete when rebuilding a library.
12995 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
12998 2006-02-13 Javier Miranda <miranda@adacore.com>
13001 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
13002 code to improve the error message reported when the program has
13003 declarations of abstract interface types and it is not compiled with
13004 the -gnat05 switch.
13005 (P_Access_Definition): Reorganize the code to improve the error
13006 message reported when the new Ada 2005 syntax for anonymous
13007 access types is used and the program is not compiled with the

13023 * prj.adb (Reset): Initialize the first element of table Namings with
13024 the standard naming data.
13026 2006-02-13 Vincent Celier <celier@adacore.com>
13028 * prj.ads (Error_Warning): New enumeration type
13030 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
13031 unknown, use the location of the project to report the error.
13032 (When_No_Sources): New global variable
13033 (Report_No_Ada_Sources): New procedure
13034 (Check): New parameter When_No_Sources. Set value of global variable
13036 (Find_Sources): Call Report_No_Ada_Sources when appropriate
13037 (Get_Sources_From_File): Ditto
13038 (Warn_If_Not_Sources): Better warning messages indicating the unit name
13041 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
13042 Call Prj.Proc.Process with parameter When_No_Sources.
13044 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
13045 Call Recursive_Check with parameter When_No_Sources.
13046 (Recursive_Check): New parameter When_No_Sources. Call itself and
13047 Prj.Nmsc.Check with parameter When_No_Sources.
13048 (Process): New parameter When_No_Sources. Call Check with parameter
13050 (Copy_Package_Declarations): New procedure to copy renamed parameters
13051 and setting the location of the declared attributes to the location
13052 of the renamed package.

13058 * prj-makr.adb (Make): Preserve the comments from the original project
13060 When removing nodes (attributes Source_Dirs, Source_Files,
13061 Source_List_File and package Naming), save the comments and attach the
13062 saved comments to the newly created nodes.
13063 Do not add a with clause for the naming package if one already exists.

13071 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
13072 aliased entities to look for the overriden abstract interface
13074 (Is_Interface_Subprogram): Complete documentation.
13075 (Check_Dispatching_Operation): Do not generate code to register the
13076 operation in the dispatch table if the source is compiled with
13077 restriction No_Dispatching_Calls.
13078 (Override_Dispatching_Operation): Check for illegal attempt to override
13079 No_Return procedure with procedure that is not No_Return
13080 (Check_Dispatching_Call): Suppress the check for an abstract operation
13081 when the original node of an actual is a tag-indeterminate attribute
13082 call, since the attribute, which must be 'Input, can never be abstract.
13083 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
13084 call to the Input attribute (even when rewritten).
13085 (Propagate_Tag): Augment comment to indicate the possibility of a call
13086 to an Input attribute.
13088 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
13089 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
13091 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
13092 No_Wide_Characters is no longer partition-wide
13093 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)

13098 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
13100 2006-02-13 Javier Miranda <miranda@adacore.com>
13102 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
13103 handles default-initialized components to keep separate the management
13104 of this feature but also avoid the unrequired resolution and
13105 expansion of components that do not have partially initialized
13107 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
13108 (Check_Bounds): Likewise.
13109 (Check_Length): Likewise.
13111 2006-02-13 Javier Miranda <miranda@adacore.com>
13112 Ed Schonberg <schonberg@adacore.com>
13114 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
13115 abstract interface type call analyze_and_resolve to expand the type
13116 conversion into the corresponding displacement of the
13117 reference to the base of the object.
13118 (Eval_Attribute, case Width): For systems where IEEE extended precision
13119 is supported, the maximum exponent occupies 4 decimal digits.
13120 (Accessibility_Message): Add '\' in 2-line warning message.
13121 (Resolve_Attribute): Likewise.
13122 (case Attribute_Access): Significantly revise checks
13123 for illegal access-to-subprogram Access attributes to properly enforce
13124 the rules of 3.10.2(32/2).
13125 Diagnose use of current instance with an illegal attribute.
13127 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
13129 (Enclosing_Generic_Unit): New function to return a node's innermost
13130 enclosing generic declaration node.
13131 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
13132 (Type_Access_Level): The accessibility level of anonymous acccess types
13133 associated with discriminants is that of the current instance of the
13134 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
13135 (Compile_Time_Constraint_Error): Handle case of conditional expression.
13136 (Kill_Current_Values_For_Entity): New function
13137 (Enter_Name): Change formal type to Entity_Id
13139 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
13140 Ed Schonberg <schonberg@adacore.com>
13141 Gary Dismukes <dismukes@adacore.com>
13143 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
13144 Analyze_Compilation_Unit.
13145 Detect and warn on redundant with clauses detected in a package spec
13146 and/or body when -gnatwr is used.

13148 (Install_Context_Items): Don't analyze config pragmas here
13149 (Install_Limited_Withed_Unit): Set limited entity of package in
13150 with_clause so that cross-reference information or warning messages on
13151 unused packages can be properly generated
13152 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
13153 has Error_Posted set. Prevent infinite loops in illegal programs.
13154 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
13155 to the point of the error test requiring the current unit to be private.
13156 This ensures that private with clauses are not exempted from the basic
13157 checking for being a descendant of the same library unit parent as a
13158 withed private descendant unit.
13159 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
13160 handle private with clauses properly, as well as to account for cases
13161 where the withed unit is a public descendant of a private ancestor
13162 (in which case the current unit must be a descendant of the private
13163 ancestor's parent). The spec comments were updated accordingly. Also,
13164 the old error message in this subprogram was replaced with error
13165 messages that mirror the errors tested and reported by
13166 Check_Private_Child_Unit.
13167 Parameter and variable names improved for readability.
13168 (Install_Limited_Context_Clauses): Remove test for a withed unit being
13169 private as the precondition for calling
13170 Check_Private_Limited_Withed_Unit since that subprogram has been
13171 revised to test public units as well as private units.

13178 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
13179 that Scope_Stack.First = 1.
13180 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13181 were not always properly handled previously.
13182 (Formal_Entity): Complete rewrite, to handle properly some complex case
13183 with multiple levels of parametrization by formal packages.
13184 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
13185 to the corresponding derived type declaration for proper semantics.
13187 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
13188 (Check_Component): Enforce restriction on components of
13189 unchecked_unions: a component in a variant cannot contain tasks or
13191 (Unchecked_Union): Allow nested variants and multiple discriminants, to
13193 Add pragma Ada_2005 (synonym for Ada_05)
13194 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13195 were not always properly handled previously.
13196 Document that pragma Propagate_Exceptions has no effect
13197 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
13198 (Set_Convention_From_Pragma): Check that if a convention is
13199 specified for a dispatching operation, then it must be
13200 consistent with the existing convention for the operation.
13201 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
13202 longer required to specify an vtable-ptr component in the record. For
13203 compatibility reasons we leave the support for the previous definition.
13204 (Analyze_Pragma, case No_Return): Allow multiple arguments
13206 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
13207 non-overrideen inherited operation with a controlling result as
13208 illegal only its implicit declaration comes from the derived type
13209 declaration of its result's type.
13210 (Check_Possible_Deferred_Completion): Relocate the object definition
13211 node of the subtype indication of a deferred constant completion rather
13212 than directly analyzing it. The analysis of the generated subtype will
13213 correctly decorate the GNAT tree.
13214 (Record_Type_Declaration): Check whether this is a declaration for a
13215 limited derived record before analyzing components.
13216 (Analyze_Component_Declaration): Diagnose record types not explicitly
13217 declared limited when a component has a limited type.
13218 (Build_Derived_Record_Type): Code reorganization to check if some of
13219 the inherited subprograms of a tagged type cover interface primitives.
13220 This check was missing in case of a full-type associated with a private
13222 (Constant_Redeclaration): Check that the subtypes of the partial and the
13223 full view of a constrained deferred constant statically match.
13224 (Mentions_T): A reference to the current type in an anonymous access
13225 component declaration must be an entity name.
13226 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
13227 class_wide type to refer to full type, not to the incomplete one.
13228 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
13229 available. Required to give support to the certified run-time.
13230 (Analyze_Component_Declaration): In case of anonymous access components
13231 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
13232 (Process_Discriminants): For an access discriminant, use the
13233 discriminant specification as the associated_node_for_itype, to
13234 simplify accessibility checks.
13236 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13237 Javier Miranda <miranda@adacore.com>
13239 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
13240 abstract interpretations on an operator, remove interpretations that
13241 yield Address or a type derived from it, if one of the operands is an
13243 (Try_Object_Operation.Try_Primitive_Operation,
13244 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
13245 location when creating the new reference to a primitive or class-wide
13246 operation as a part of rewriting a subprogram call.
13247 (Try_Primitive_Operations): If context requires a function, collect all
13248 interpretations after the first match, because there may be primitive
13249 operations of the same type with the same profile and different return
13250 types. From code reading.
13251 (Try_Primitive_Operation): Use the node kind to choose the proper
13252 operation when a function and a procedure have the same parameter
13254 (Complete_Object_Operation): If formal is an access parameter and prefix
13255 is an object, rewrite as an Access reference, to match signature of
13256 primitive operation.
13257 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
13258 by an expanded name with prefix Standard, when the operands are of an
13259 anonymous access type.
13260 (Remove_Abstract_Operations): If the operation is abstract because it is
13261 inherited by a user-defined type derived from Address, remove it as
13262 well from the set of candidate interpretations of an overloaded node.
13263 (Analyze_Membership_Op): Membership test not applicable to cpp-class
13266 2006-02-13 Bob Duff <duff@adacore.com>
13268 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
13269 redundant use clauses.
13270 In particular, if the scope of two use clauses overlaps, but one is not
13271 entirely included in the other, we should not warn. This can happen
13272 with nested packages.
13273 (Analyze_Subprogram_Renaming): Protect the compiler against previously
13274 reported errors. The bug was reported when the compiler was built
13275 with assertions enabled.
13276 (Find_Type): If the node is a 'Class reference and the prefix is a
13277 synchronized type without a corresponding record, return the type
13280 2006-02-13 Javier Miranda <miranda@adacore.com>
13282 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
13283 if this is the full-declaration associated with a private declaration
13284 that implement interfaces, then the private type declaration must be
13286 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
13287 as aliased. The use of the 'access attribute is not available for such
13288 object (for this purpose the object should be explicitly marked as
13289 aliased, but being an anonymous type this is not possible).
13291 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13292 Robert Dewar <dewar@adacore.com>
13294 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
13295 compilation unit is an elaboration scope.
13296 (Add_Task_Proc): Add '\' in 2-line warning message.
13297 (Activate_All_Desirable): Deal with case of unit with'ed by parent
13299 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13300 Javier Miranda <miranda@adacore.com>
13302 * sem_type.adb (Write_Overloads): Improve display of candidate
13304 (Add_One_Interp): Do not add to the list of interpretations aliased
13305 entities corresponding with an abstract interface type that is an
13306 immediate ancestor of a tagged type; otherwise we have a dummy
13307 conflict between this entity and the aliased entity.
13308 (Disambiguate): The predefined equality on universal_access is not
13309 usable if there is a user-defined equality with the proper signature,
13310 declared in the same declarative part as the designated type.
13311 (Find_Unique_Type): The universal_access equality operator defined under
13312 AI-230 does not cover pool specific access types.
13313 (Covers): If one of the types is a generic actual subtype, check whether
13314 it matches the partial view of the other type.
13316 2006-02-13 Thomas Quinot <quinot@adacore.com>
13318 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
13319 line. This is necessary to allow In_Extended_Main_Unit to provide
13320 correct results for itypes while writing out expanded source.
13321 (Close_File): No need to update the source_index_table here since it's
13322 now done for each line.
13324 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13325 Robert Dewar <dewar@adacore.com>
13327 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
13328 preserve the source unit where the itype is declared, and prevent a

13338 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
13341 2006-02-13 Bob Duff <duff@adacore.com>
13343 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
13344 Scan_Unsigned, so we do not scan leading blanks and sign twice.
13345 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13346 raise Constraint_Error.
13348 * s-vallli.adb (Scan_Long_Long_Integer): Call
13349 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
13350 do not scan leading blanks and sign twice.
13351 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13352 raise Constraint_Error.
13354 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
13355 Scan_Long_Long_Unsigned): Split out most of the processing from
13356 Scan_Long_Long_Unsigned out into
13357 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
13358 This prevents scanning leading blanks and sign twice.
13359 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
13362 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
13363 out most of the processing from Scan_Unsigned out into
13364 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
13365 This prevents scanning leading blanks and sign twice.
13367 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
13368 use with Modular'Value attribute.
13369 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
13372 2006-02-13 Robert Dewar <dewar@adacore.com>
13374 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

13565 Florian Villoing <villoing@adacore.com>
13567 * a-taster.ads, a-taster.adb: New files.
13569 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
13570 link to the version that does nothing. This way the task termination
13571 routine is not executed twice for the environment task when finishing
13572 because of an unhandled exception.
13574 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
13575 handler because of an unhandled exception.
13577 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
13578 System.Tasking.Utilities instead of that in System.Tasking.Stages.
13580 * s-finimp.adb (initialization code): Modify the soft link for the
13581 finalization of the global list instead of Adafinal.
13583 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
13584 non-tasking version of the soft link for task termination. We do
13585 nothing since if we are using the non-tasking version it
13586 means that the task termination functionality is not used.
13587 (Null_Finalize_Global_List): Add this null version for the procedure
13588 in charge of finalizing the global list for controlled objects.
13589 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
13590 instead for handling run-time termination in a more flexible way.
13591 (Adafinal_NT): This new procedure will take care of finalizing the
13592 global list for controlled objects if needed, but no tasking
13595 * s-tarest.adb (Task_Lock): Do not try to lock again the
13596 Global_Task_Lock if we already own it. Otherwise, we get blocked in
13597 some run-time operations.
13598 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
13599 until all nested locks have been released.
13600 (Task_Wrapper): Call the fall-back task termination handler. It
13601 applies to all tasks but the environment task.
13602 (Finalize_Global_Tasks): Add the call for the task termination
13603 procedure for the environment task.
13604 (Task_Wrapper): suppress warnings around declaration of
13605 Secondary_Stack_Address.
13607 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
13608 moved to the Common_ATCB record.
13609 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
13610 Common_ATCB record.
13611 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
13612 Common_ATCB record.
13614 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
13615 Fall_Back_Handler, and Specific_Handler.
13617 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
13618 defined in Ada.Task_Termination, to avoid circular dependencies.
13619 (Termination_Handler): Redefine this type here, alredy defined in
13620 Ada.Task_Termination, for avoiding circular dependencies.
13621 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
13622 for storing task termination handlers. In addition,
13623 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
13624 Common_ATCB because it is used by both the regular and the restricted
13626 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
13627 Common_ATCB because it is used by both the regular and the restricted
13629 (Common_ATCB): Added a dynamic task analyzer field.
13631 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
13632 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
13633 (Task_Wrapper): Call the task termination handler. It applies to all
13634 tasks but the environment task.
13635 (Finalize_Global_Tasks): Call the task termination procedure for the
13636 environment task. The call to Finalize_Global_List is now performed
13637 using the soft links mechanism.
13638 (Task_Wrapper): added dynamic stack analysis.
13640 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
13641 potentially blocking operations has been moved from
13642 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
13643 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
13644 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
13645 this run-time check.
13647 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
13648 of task termination procedure.
13649 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
13650 link for the task termination procedure.
13652 * bindusg.adb: (Bindusg): Added documentation for -u option.

13662 * opt.ads: Added flags used by dynamic stack measurement.
13663 (Max_Line_Length): Remove (not used anymore)
13665 * s-io.ads, s-io.adb (Standard_Error): new subprogram
13666 (Standart_Output): new subprogram
13667 (Set_Output): new subprogram
13668 (Put): now uses the value of Current_Out to know if the output has to be
13669 send to stderr or stdout.
13671 * s-stausa.ads: Complete implementation.
13673 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
13675 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
13676 list of Ada 05 files.
13677 (GNAT Library Units): Add AltiVec files.
13679 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
13680 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
13681 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
13683 2005-12-09 Nicolas Setton <setton@adacore.com>
13685 * adaint.c (__gnat_locate_regular_file): Return immediately if
13686 file_name is empty.
13688 2005-12-09 Javier Miranda <miranda@adacore.com>
13689 Hristian Kirtchev <kirtchev@adacore.com>
13691 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
13692 to the specification because the frontend generates code that uses this
13694 (Set_Interface_Table): Add missing assertion.
13695 Update documentation describing the run-time structure.
13696 (Displace): New subprogram that displaces the pointer to the object
13697 to reference one of its secondary dispatch tables.
13698 (IW_Membership): Modified to use the new table of interfaces.
13699 (Inherit_TSD): Modified to use the new table of interfaces.
13700 (Register_Interface_Tag): Use the additional formal to fill the
13701 contents of the new table of interfaces.
13702 (Set_Interface_Table): New subprogram that stores in the TSD the
13703 pointer to the table of interfaces.
13704 (Set_Offset_To_Top): Use the additional formal to save copy of
13705 the offset value in the table of interfaces.
13706 Update structure of GNAT Primary and Secondary dispatch table diagram.
13707 Add comment section on GNAT dispatch table prologue.
13708 (Offset_To_Signature): Update the constant value of the Signature field.
13709 (Dispatch_Table): Update comment on hidden fields in the prologue.

13711 Set_Entry_Index, Set_Offset_Index, Set_Prim_Op_Kind, SSD, TSD): Change
13712 the type of formal parameter T to Tag, introduce additional assertions.
13713 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
13715 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
13717 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
13718 in all the calls to Expand_Interface_Thunk. Instead of referencing the
13719 record component containing the tag of the secondary dispatch table we
13720 have to use the Offset_To_Top run-time function to get this information;
13721 otherwise if the pointer to the base of the object has been displace
13722 we get a wrong value if we use the 'position attribute.
13724 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
13725 all the calls to Expand_Interface_Thunk.
13726 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
13727 interfaces; hence the call to Set_Interface_Table was clearly wrong.
13728 (Collect_All_Interfaces): Modify the internal subprogram Collect to
13729 ensure that the interfaces implemented by the ancestors are placed
13730 at the header of the generated list.
13731 (Expand_Interface_Conversion): Handle the case in which the displacement
13732 associated with the interface conversion is not statically known. In
13733 this case we generate a call to the new run-time subprogram Displace.
13734 (Make_DT): Generate and fill the new table of interfaces.
13735 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
13736 Get_Tagged_Kind and Set_Tagged_Kind.
13737 (Tagged_Kind): New function that determines the tagged kind of a type
13738 with respect to limitedness and concurrency and returns a reference to
13740 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
13741 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
13742 primary dispatch table for a type.
13743 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
13744 secondary dispatch table respectively of a tagged type.
13746 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
13747 (Expand_Interface_Conversion): New subprogram to indicate if the
13748 displacement of the type conversion is statically known.
13749 (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
13751 * rtsfind.ads (RE_Offset_To_Top): New entity
13752 (RTU_Id): Add Ada_Task_Termination to the list so that it is made
13753 accessible to users.
13754 (Re_Displace): New entity
13755 (RE_Interface_Data): New entity

13969 (Derived_Type_Declaration): If the parent of the full-view is an
13970 interface perform a transformation of the tree to ensure that it has
13971 the same parent than the partial-view. This simplifies the job of the
13972 expander in order to generate the correct object layout, and it is
13973 needed because the list of interfaces of the full-view can be given in
13975 (Process_Full_View): The parent of the full-view does not need to be
13976 a descendant of the parent of the partial view if both parents are

13993 (Process_Full_View): Improve the check for the "no hidden interface"
13994 rule as defined by AI-396.

14053 available user-specified stream attributes on limited parameters to
14054 also test the type directly rather than only its underlying type (for
14055 Ada 95) and, in the case of Ada 2005, to check that the user-specified
14056 attributes are visible at the point of the subprogram declaration.
14057 For Ada 2005, the error message is modified to indicate that the
14058 type's stream attributes must be visible (again, only for -gnat05).

14090 types use the corresponding record type. This was not needed before
14091 the implementation of Ada 2005 synchronized types because
14092 concurrent types were never tagged types in Ada 95.

14220 * socket.c: Add extern int h_errno for rtems since networking header
14221 files are not available at this point in a tool bootstrap. Newlib

14338 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for

14497 we are not defining the type.
14498 <E_Record_Type>: Likewise.
14499 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
14500 to get advantage of the new maybe_stabilize_reference interface, to

14503 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
14504 type imported through a limited_with clause, use its non-limited view.
14505 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

14514 that we are not defining.
14515 (elaborate_expression_1): Do not create constants when creating
14516 variables needed by the debug info: the dwarf2 writer considers that
14517 CONST_DECLs is used only to represent enumeration constants, and emits
14519 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
14520 object with an address clause into an indirect reference, drop the
14521 initializing expression.

14535 is provided by the front-end, use that subtype to compute the size of
14536 the deallocated object.

14543 maybe_stabilize, for common uses without restriction on lvalues and
14544 without need to check for the success indication.
14545 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
14546 pass false instead of 0 as the FORCE argument which is a bool.
14547 (Identifier_to_gnu): Remove checks ensuring that an renamed object
14548 attached to a renaming pointer has been properly stabilized, as no such
14549 object is attached otherwise.
14550 (call_to_gnu): Invoke create_var_decl to create the temporary when the
14551 function uses the "target pointer" return mechanism.
14552 Reinstate conversion of the actual to the type of the formal
14553 parameter before any other specific treatment based on the passing

14564 static output of record constructor if all the components are constant.
14565 (gnat_build_constructor): For a record type, sort the list of field
14566 initializers in increasing bit position order.

14568 from a fat or thin pointer type and a constrained object type.
14569 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
14570 types variants, and process special cases of VIEW_CONVERT expressions
14571 as their NOP_EXPR counterpart to ensure we get to the
14572 CORRESPONDING_VARs associated with CONST_DECls.
14573 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
14574 on the right-hand side.

14581 extracting the object if converting to a type variant.
14582 (create_var_decl): When a variable has an initializer requiring code
14583 generation and we are at the top level, check for a potential violation
14584 of a No_Elaboration_Code restriction.
14585 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
14586 SIZE and SIZE_UNIT which we need for later back-annotations.

14730 object declaration will create it earlier. Otherwise, in the case of a
14731 nested aggregate, the object may appear in the wrong scope.
14732 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
14733 (Gen_Assign): If the component being assigned is an array type and the
14734 expression is itself an aggregate, wrap the assignment in a block to
14735 force finalization actions on the temporary created for each row of the
14737 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
14738 structures are initialized after all discriminants are set so that
14739 they can be accessed even when their offset is dynamic.

14748 'Terminated whenever the prefix is of a task interface class-wide type.
14749 (Analyze_Attribute): Add semantic check for attribute 'Identity whenever
14750 the prefix is of a task interface class-wide type.
14752 * s-vaflop-vms-alpha.adb: Valid_D, Valid_F, Valid_G: Make Val constant

14767 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
14768 and related): For a prefix that is an explicit dereference of an
14769 access to unconstrained packed array type, annotate the dereference
14770 with an actual subtype so GIGI can make a correct size computation.
14771 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
14772 'Unrestricted_Access, if the designated type is an interface we
14773 add a type conversion to force the displacement of the pointer
14774 to the secondary dispatch table.
14775 Use Universal_Real instead of Long_Long_Float when we need a high
14776 precision float type for the generated code (prevents gratuitous
14777 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
14778 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
14779 'Terminated for task interface class-wide objects. Generate a call to
14780 the predefined dispatching routine used to retrieve the _task_id from

14803 necessary for the statements within the block: analyze it with checks
14805 (Expand_N_If_Statement): When killing a dead then-branch in an
14806 if-statement that has elsif_parts, recompute the Current_Value node
14807 for any entity whose value is known from the condition of the first
14809 (Expand_N_Return_Statement): When returning a mutable record, convert
14810 the return value into its actual subtype in order to help the backend
14811 to return the actual size instead of the maximum. This is another
14812 aftermath of not returning mutable records on the sec-stack anymore.
14814 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
14815 handling of error msg for suspicious reverse range iteration.
14816 (Check_Possible_Current_Value_Condition): Move declaration from body to

14861 attribute of the N_Free_Statement.
14862 Generate itype for classwide designated object in both cases of
14863 user-specified storage pool: specific and class-wide, not only in the
14865 Raise CE when trying to set a not null access type object to null.
14866 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
14867 an explicit loop, because freeze nodes make its position variable.

15045 rhs of an assignment even if the type is unconstrained, when the
15046 context is non-expanding.
15047 In an inlined body, if the context type is private,
15048 resolve with its full view, which must be a composite type.

15086 parent scopes of a scope being removed prior to inlining an instance
15088 (Analyze_Package_Instantiation): Do not perform front-end inlining when

15104 scope against package Standard. Add comments and a ??? comment.
15105 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
15106 on a child instance parent to test that the parent equals

15123 (Build_Private_Derived_Type): The entity of the created full view of the
15124 derived type does not come from source. If after installing the private

15126 full view to construct the full declaration of the derived type.
15127 (Build_Derived_Record_Type): Relax the condition that controls the
15128 execution of the check that verifies that the partial view and

15137 view is a transitive derivation of the ancestor of the partial view.
15138 (Process_Full_View): Rename local subprogram Find_Interface_In_
15139 Descendant to Find_Ancestor_Interface to leave the code more clear.
15140 Remove wrong code that avoids the generation of an error message
15141 when the immediate ancestor of the partial view is an interface.
15142 In addition some minor reorganization of the code has been done to
15143 leave it more clear.
15144 (Analyze_Type_Declaration): If type has previous incomplete tagged
15145 partial view, inherit properly its primitive operations.
15146 (Collect_Interfaces): Make public, for analysis of formal

15159 be included in the interface list.
15160 (Access_Definition): If the designated type is an interface that may
15161 contain tasks, create Master_Id for it before analyzing the expression
15162 of the declaration, which may be an allocator.
15163 (Record_Type_Declaration): Set properly the interface kind, for use
15164 in allocators, the creation of master id's for task interfaces, etc.

15173 subprogram declaration.
15174 Change name Is_Package to Is_Package_Or_Generic_Package
15175 (Process_Formals): A non null qualifier on a non null named access
15176 type is not an error, and is a warning only if Redundant_Constructs

15180 Ed Schonberg <schonberg@adacore.com>
15182 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
15183 nested within Analyze_Package_Specification to install the private
15184 declarations and use clauses within each of the parent units of a
15185 package instance of a generic child package.

15187 package associated with a generic instance or formal package, the
15188 private declarations of the parent must be installed (by calling new
15189 procedure Install_Parent_Private_Declarations).
15190 Change name Is_Package to Is_Package_Or_Generic_Package
15191 (Preserve_Full_Attributes): For a synchronized type, the corresponding

15197 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
15198 not try to rewrite a renamed stream attribute, because the operations
15199 on the type may not have been generated.
15200 Handle properly a renaming_as_body generated for a stream operation
15201 whose default is abstract because the object type itself is abstract.
15202 (Find_Type): If the type is incomplete and appears as the prefix of a
15203 'Class reference, it is tagged, and its list of primitive operations
15204 must be initialized properly.
15205 (Chain_Use_Clauses): When chaining the use clauses that appear in the
15206 private declaration of a parent unit, prior to compiling the private
15207 part of a child unit, find on the scope stack the proper parent entity
15208 on which to link the use clause.

15217 * sem_eval.adb: Implement d.f flag
15218 (Subtype_Statically_Match): A generic actual type has unknown
15219 discriminants when the corresponding actual has a similar partial view.

15232 remove address operations.
15233 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
15234 statement to inhibit warning.
15235 (Resolve_Unary_Op): Do not produce a warning when
15236 processing an expression of the form -(A mod B)
15237 Use Universal_Real instead of Long_Long_Float when we need a high
15238 precision float type for the generated code (prevents gratuitous
15239 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
15240 (Resolve_Concatenation_Arg): Improve error message when argument is an
15241 ambiguous call to a function that returns an array.
15242 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
15243 there is an implicit operator in the given scope if we are within an
15244 instance: legality check has been performed on the generic.
15245 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
15246 after resolving operand, to avoid false warnings on overloaded calls.

15255 previously detected errors to ensure that its compilation
15256 with assertions enabled gives the same output that its
15257 compilation without assertions.
15258 (Interface_Present_In_Ancestor): Add support for private types.
15259 Change name In_Actual to In_Generic_Actual (clean up)
15260 (Disambiguate): New predicate In_Actual, to recognize expressions that
15261 appear in the renaming declaration generated for generic actuals, and
15262 which must be resolved in the outer context.

15941 * exp_disp.ads, exp_disp.adb (Default_Prim_Op_Position): Return a
15942 predefined position in the dispatch table for the primitive operations
15943 used in dispatching selects.
15944 (Init_Predefined_Interface_Primitives): Remove the hardcoded number of
15945 predefined primitive operations and replace it with
15946 Default_Prim_Op_Count.
15947 (Make_Disp_Asynchronous_Select_Spec, Make_Disp_Conditional_Select_Spec,
15948 Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Update
15949 the names of the generated primitive operations used in dispatching
15951 (Init_Predefined_Interface_Primitives): No need to inherit primitives in
15952 case of abstract interface types. They will be inherit by the objects
15953 implementing the interface.
15954 (Make_DT): There is no need to inherit the dispatch table of the
15955 ancestor interface for the elaboration of abstract interface types.
15956 The dispatch table will be inherited by the object implementing the
15958 (Copy_Secondary_DTs): Add documentation.

15963 the entries associated with predefined primitives of all the secondary
15965 (Build_Anonymous_Access_Type): Removed.
15966 (Expand_Interface_Actuals): With the previous cleanup there is no need
15967 to build an anonymous access type. This allows further cleanup in the
15968 code generated by the expander.
15969 (Expand_Interface_Conversion): If the actual is an access type then
15970 build an internal function to handle the displacement. If the actual
15971 is null this function returns null because no displacement is
15972 required; otherwise performs a type conversion that will be
15973 expanded in the code that returns the value of the displaced actual.
15974 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
15975 conversions that have no effect in the generated code because no
15976 displacement is required. Code cleanup; use local variables to
15977 avoid repeated calls to the subprogram directly_designated_type().
15979 * exp_util.ads, exp_util.adb (Is_Predefined_Dispatching_Operation):
15980 Classify the primitive operations used in dispatching selects as
15982 (Implements_Limited_Interface): Determine whether some type either

15984 implements a limited interface.
15985 (Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
15986 (Expand_Subtype_From_Expr): Do not build actual subtype if the
15987 expression is limited.
15988 (Find_Interface_Tag): Add code to handle class-wide types and
15989 entities from the limited-view.
15991 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
15992 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,
15993 POK_Protected_Entry, POK_Protected_Function, POK_Protected_Procedure,
15994 POK_Task_Entry, POK_Task_Procedure, Prim_Op_Kind, Set_Entry_Index,
15997 * sem_ch9.adb (Analyze_Triggering_Alternative): Check for legal type
15998 of procedure name or prefix that appears as a trigger in a triggering
16001 * uintp.ads: Introduce constants Uint_11 and Uint_13.

16016 * s-taprop-vxworks.adb:
16017 Move with clauses outside Warnings Off now that dependent units are
16019 (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
16020 initialization of this unit.
16021 (Specific): Add new procedures Initialize and Delete so that this
16022 package can be used for VxWorks 5.x and 6.x
16023 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
16024 differences between VxWorks 5.x and 6.x
16025 Minor reformatting.
16026 (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by
16028 Use only Preelaborate-compatible constructs.
16030 * s-tpopsp-vxworks.adb (ATBC_Key, ATCB_Key_Addr): Moved from
16031 Primitives.Operations.
16032 (Delete, Initialize): New procedures.

16040 (VX_FP_TASK): Now a function, to handle differences between VxWorks 5
16042 (Set_Time_Slice): New function, replacing kerneltimeSlice to share code
16043 between Vxworks 5 and 6.
16044 (taskLock, taskUnlock): Removeed, no longer used.
16046 * adaint.c: The wait.h header is not located in the sys directory on
16047 VxWorks when using RTPs.
16048 (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
16050 (__gnat_dup): dup is available on Vxworks when using RTPs.
16051 (__gnat_dup2): dup2 is available on Vxworks when using RTPs.
16053 * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs.
16055 * expect.c: The wait.h header is not located in the sys directory on
16056 VxWorks when using RTPs.

16069 SO_RCVTIMEO/SO_SNDTIMEO
16073 Move all target-specific file inclusions and macro definitions to
16074 gsocket.h, in order to ensure that any C code in socket.c will see a
16075 set of constants that is consistent with the contents of g-soccon.ads.
16077 * gsocket.h: Code imported from gen-soccon.c:
16078 Move all target-specific file inclusions and macro definitions to
16079 gsocket.h, in order to ensure that any C code in socket.c will see a set
16080 of constants that is consistent with the contents of g-soccon.ads.
16081 This change also makes gen-soccon self-contained (removing dependencies
16082 upon GCC internal headers).
16084 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
16086 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
16088 * socket.c: Minor reformatting.

16220 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
16221 from object notation, the original node is unanalyzed and carries no
16222 semantic information, so that accessiblity checks must be performed on
16223 the type of the actual itself.
16224 (Expand_N_Subprogram_Declaration): Change last actual parameter for
16225 compatibility with Build_Protected_Sub_Specification.
16226 (Check_Overriding_Inherited_Interfaces): Add suport to handle

16236 load comes from a Limited_With_Clause.
16238 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
16239 whether a potential circularity is harmless, because it includes units
16240 loaded through a limited_with clause. Extends previous treatment which
16241 did not handle properly arbitrary combinations of limited and
16242 non-limited clauses.
16244 2005-09-01 Nicolas Setton <setton@adacore.com>
16246 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

16276 2005-09-01 Laurent Pautet <pautet@adacore.com>
16278 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
16279 position set is provided, we compute one in order to reduce the maximum
16280 length of the keys. This computation first selects a character
16281 position between 1 and the minimum length of the keys in order to
16282 avoid reducing one of the keys to an empty string.
16283 (Initialize, Compute): When the ratio V to K is too low, the algorithm
16284 does not converge. The initialization procedure now comes with a
16285 maximum number of iterations such that when exceeded, an exception is
16286 raised in Compute. The user can initialize this ratio to another value
16288 Reformating and updated headers.

16292 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
16293 that given an entity T creates and returns an Itype that duplicates the
16294 contents of T. The returned Itype has the null-exclusion
16295 attribute set to True, and its Etype attribute references T
16296 to keep the association between the two entities.
16297 Update copyright notice
16299 * sem_aggr.adb (Check_Can_Never_Be_Null,
16300 Aggregate_Constraint_Checks, Resolve_Aggregate,
16301 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.

16320 (P_Access_Type_Definition): Add parsing for an anonymous access result
16321 subtype, plus parsing for null exclusions. Call Set_Result_Definition
16322 instead of Set_Subtype_Mark.
16324 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
16325 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
16326 (Result_Definition): New function for N_Function_Specifications.

16328 N_Function_Specification.
16329 (Set_Null_Exclusion_Present): Allow this flag for
16330 N_Function_Specification.
16331 (Set_Result_Definition): New procedure for N_Function_Specifications.
16332 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
16333 and N_Function_Specification.
16335 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
16336 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
16337 Add support for LIMITED NEW for Ada 2005 AI-419
16338 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
16339 syntax for anonymous access results.

16341 N_Function_Specification and N_Access_Definition specs.
16342 Add Null_Exclusion_Present to spec of N_Function_Specification.
16343 (Result_Definition): New function for N_Function_Specification and
16344 N_Access_Function_Definition.

16349 Result_Definition for cases of N_Access_Function_Definition and
16350 N_Function_Specification.
16351 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
16353 2005-09-01 Vincent Celier <celier@adacore.com>
16355 * lib-writ.adb: Update Copyright notice
16356 (Write_With_Lines): On platforms where file names are case-insensitive,
16357 record the file names in lower case.
16358 (Write_ALI): For D lines, on platforms where file names are
16359 case-insensitive, record the file names in lower case.

16378 including those that are inherited.

16382 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
16384 * par-prag.adb: Implement new pragma Debug_Policy
16386 * sem_prag.adb Implement new pragma Debug_Policy
16387 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
16388 Component_Size attribute specification. Give warning for ignored pragma
16391 * snames.h, snames.ads, snames.adb: Introduce entries in
16392 Preset_Names for Name_Disp_Asynchronous_Select,
16393 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
16394 Name_Disp_Timed_Select.
16395 New pragma Debug_Policy

16399 Switch -gnata also sets Debug_Pragmas_Enabled
16401 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
16402 handle an explicit -gnata when compiling predefined files.

16407 directories of projects that have no Ada sources.
16409 2005-09-01 Robert Dewar <dewar@adacore.com>
16411 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
16412 (makes a difference for wide characters)
16414 * widechar.adb, widechar.ads:
16415 Add Wide_Char_Byte_Count feature to count chars vs bytes

16418 Ed Schonberg <schonberg@adacore.com>
16419 Robert Dewar <dewar@adacore.com>
16421 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
16422 'Address attribute reference with an overloaded prefix, use the
16423 location of the prefix (not the location of the attribute reference) as
16424 the error location.
16425 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
16426 a function renaming thereof, is a valid prefix for 'Size (where it is
16427 intepreted as a function call).
16428 (Statically_Denotes_Entity): New predicate to determine whether the
16429 prefix of an array attribute can be considered static.
16432 (Eval_Attr): Fix failure to evaluate Component_Size for
16433 unconstrained arrays (resulted in wrong value in packed case, since
16434 back end cannot handle this case)
16436 2005-09-01 Robert Dewar <dewar@adacore.com>
16438 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
16439 error msgs for most common cases.
16440 Use new errout insertion char < (conditional warning)
16442 2005-09-01 Javier Miranda <miranda@adacore.com>
16443 Ed Schonberg <schonberg@adacore.com>
16445 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
16446 become local to the whole package.
16447 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
16448 the package was already analyzed the new algorithm "replaces" the
16449 real entities by the shadow ones. This is required to ensure that
16450 the order of these entities in the homonym chains does not change;
16451 otherwise we can have undefined references at linking time because
16452 in case of conflicts the external name of the entities will have
16453 a suffix that depends on the order of the entities in the chain.
16454 (Remove_Limited_With_Clause): Complementary code that completes the
16455 new algorithm and replaces the shadow entities by the real ones.
16456 (Install_Limited_Withed_Unit): When unchaining entities before the
16457 installation of the shadow entities, only regular entities of the
16458 public part must be taken into account. This is required to
16459 keep this routine in synch with the work done by Remove_Limited_
16461 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
16462 even if unit is analyzed, because the analysis of the unit is
16463 idempotent in any case, and the limited view of the unit may have to
16464 be installed for proper visibility.
16465 (Expand_Limited_With_Clause): Even if the unit in the implicit
16466 with_clause has been analyzed already, a limited view of the package
16467 must be built for the current context, if it does not exist yet.
16469 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16470 Javier Miranda <miranda@adacore.com>
16471 Gary Dismukes <dismukes@adacore.com>
16473 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
16474 defining entity for the instance body, make a new defining identifier
16475 rather than copying the entity of the spec, to prevent accidental
16476 sharing of the entity list.
16477 (Check_Private_View): When exchanging views of private types, build the
16478 list of exchanged views as a stack, to ensure that on exit the exchanges
16479 are undone in the proper order.
16480 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
16481 Restore the compilation environment in case of instantiation_error.
16482 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
16483 for an anonymous access result.
16484 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
16485 (Formal_Entity): Handle properly the case of a formal package that
16486 denotes a generic package renaming.
16488 2005-09-01 Thomas Quinot <quinot@adacore.com>
16490 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
16491 clause if the array aggregate is surrounded by parentheses.
16493 2005-09-01 Cyrille Comar <comar@adacore.com>
16494 Gary Dismukes <dismukes@adacore.com>
16495 Ed Schonberg <schonberg@adacore.com>
16496 Javier Miranda <miranda@adacore.com>
16498 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
16500 to check if a type is Constrained in cases related to code generation
16501 (rather than semantic checking) since otherwise we do not generate
16502 similar code for mutable private types depending if their
16503 discriminants are visible or not.
16504 (Check_Abstract_Overriding): Do not complain about failure to override
16505 the primitive operations used in dispatching selects since they will
16506 always be overriden at the freeze point of the type.
16507 (Access_Definition): Separate out handling for resetting the scope
16508 of an anonymous access function result type. Retrieve the scope
16509 of the associated function rather than using Current_Scope, which
16510 does not have a consistent value (depends on whether we're in the
16511 middle of analyzing formal parameters). Add ??? comment about
16512 finding a cleaner way to handle the special cases of scope setting.
16513 (Process_Incomplete_Dependents): A protected operation is never a
16514 dispatching operation (only its wrapper may be).
16515 (Build_Derived_Record_Type): In case of tagged private types that
16516 implement interfaces add derivation of predefined primitive
16518 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
16519 by two parameters that are used in case of derivation from abstract
16520 interface types: No_Predefined_Prims is used to avoid the derivation
16521 of predefined primitives from the interface, and Predefined
16522 Prims_Only is used to complete the derivation predefined primitives
16523 in case of private tagged types implementing interfaces.
16524 Fix typo in comments
16525 (Find_Interface_In_Descendant): Protect the frontend against
16526 wrong code with large circularity chains.
16527 (Is_Private_Overriding): Add support for entities overriding interface
16528 subprograms. The test failed because Entities associated with overriden
16529 interface subprograms are always marked as hidden (and used to build
16530 the secondary dispatch table); in this case the overriden entity is
16531 available through the field abstract_interface_alias (cf. override_
16532 dispatching_operation)
16533 (Access_Definition): Set the scope of the type to Current_Scope for the
16534 case of a function with an anonymous access result type.
16535 (Access_Subprogram_Declaration): Handle creation of the type entity for
16536 an access-to-function type with an anonymous access result.
16537 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
16538 in handling for N_Access_Function_Definition.
16539 (Analyze_Subtype_Declaration): Modify the text of error message.
16540 (Derived_Type_Declaration): Modify the text of error message.
16541 (Process_Subtype): Modify the text of error message plus cleanup
16542 of one redundant error message.
16543 (Analyze_Component_Declaration): Code cleanup.
16544 (Analyze_Object_Declaration): Code cleanup.
16545 (Analyze_Subtype_Declaration): Propagate the null-exclusion
16546 attribute in case of access types. Code cleanup.
16547 (Array_Type_Declaration): Code cleanup.
16548 (Process_Discriminants): Create the new null-excluding itype
16549 if required. Code cleanup.
16550 (Process_Subtype): Create the new null-excluding itype if
16551 required. Code cleanup.
16552 (Build_Derived_Record_Type): Code cleanup to avoid calling
16553 twice the subprogram derive_subprograms in case of private
16554 types that implement interfaces. In this particular case the
16555 subprogram Complete_Subprograms_Derivation already does the
16556 job associated with the second call.
16558 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
16559 conversion to the full view when generating an operation for a
16560 discriminant whose type may currently be private.
16562 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16563 Javier Miranda <miranda@adacore.com>
16565 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
16566 V (Obj.F), the rewriting does not involve the indexed component, but
16567 only the selected component itself.
16568 Do not apply the transformation if the analyzed node is an actual of a
16569 call to another subprogram.
16570 (Complete_Object_Operation): Retain the entity of the
16571 dispatching operation in the selector of the rewritten node. The
16572 entity will be used in the expansion of dispatching selects.
16573 (Analyze_One_Call): Improve location of the error message associated
16575 (Analyze_Selected_Component): No need to resolve prefix when it is a
16576 function call, resolution is done when parent node is resolved, as
16578 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
16579 when attempting to resolve a call transformed from its object notation.
16580 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
16581 of the argument list for each interpretation of the operation.
16582 (Try_Object_Operation): The designated type of an access parameter may
16583 be an incomplete type obtained through a limited_with clause, in which
16584 case the primitive operations of the type are retrieved from its full
16586 (Analyze_Call): If this is an indirect call, and the return type of the
16587 access_to_subprogram is incomplete, use its full view if available.
16589 2005-09-01 Javier Miranda <miranda@adacore.com>
16590 Gary Dismukes <dismukes@adacore.com>
16592 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
16593 access types the null-exclusion and access-to-constant attributes must
16595 (Analyze_Return_Statement): When the result type is an anonymous access
16596 type, apply a conversion of the return expression to the access type
16597 to ensure that appropriate accessibility checks are performed.
16598 (Analyze_Return_Type): For the case of an anonymous access result type,
16599 generate the Itype and set Is_Local_Anonymous_Access on the type.
16600 Add ??? placeholder for check to disallow returning a limited object
16601 in Ada 2005 unless it's an aggregate or a result of a function call.
16602 Change calls from Subtype_Mark to Result_Definition.
16603 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
16604 Result_Definition in call to Make_Function_Specification.
16605 (Build_Body_To_Inline): Change Set_Subtype_Mark to
16606 Set_Result_Definition.
16607 (Make_Inequality_Operator): Change formal Subtype_Mark to
16608 Result_Definition in call to Make_Function_Specification.
16609 (Process_Formals): Create the new null-excluding itype if required.
16610 (New_Overloaded_Entity): For an entity overriding an interface primitive
16611 check if the entity also covers other abstract subprograms in the same
16612 scope. This is required to handle the general case, that is, overriding
16613 other interface primitives and overriding abstract subprograms inherited
16614 from some abstract ancestor type.
16615 (New_Overloaded_Entity): For an overriding entity that comes from
16616 source, note the operation that it overrides.
16617 (Check_Conformance, Type_Conformant): Addition of one new formal
16618 to skip controlling formals in the analysis. This is used to
16619 handle overloading of abstract interfaces.
16620 (Base_Types_Match): Add missing case for types imported from
16621 limited-with clauses
16622 (New_Overloaded_Entity): Add barrier to protect the use of
16623 the "alias" attribute.
16625 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16627 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
16628 verify that the procedure and the entry are mode conformant.
16629 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
16630 as a different operator, which is often a cut-and-paste error.
16632 2005-09-01 Javier Miranda <miranda@adacore.com>
16633 Ed Schonberg <schonberg@adacore.com>
16635 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
16636 used in controlling parameters exclude null because it is necessary to
16637 read the tag to dispatch, and null has no tag.
16638 (Override_Dispatching_Operation): If the previous operation is inherited
16639 from an interface, it becomes hidden and does not participate in later
16642 2005-09-01 Javier Miranda <miranda@adacore.com>
16643 Ed Schonberg <schonberg@adacore.com>
16644 Gary Dismukes <dismukes@adacore.com>
16646 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
16647 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
16648 the expander will generate the corresponding run-time check to evaluate
16650 (Resolve_Call): Check for legal type of procedure name or prefix that
16651 appears as a trigger in a triggering alternative.
16652 (Valid_Conversion): If expression is ambiguous and the context involves
16653 an extension of System, remove System.Address interpretations.
16654 (Resolve_Qualified_Expression): Reject the case of a specific-type
16655 qualification applied to a class-wide argument. Enhance comment
16656 to explain checking of Original_Node.
16657 (Resolve_Type_Conversion): The location of the error message was not
16658 general enough to handle the general case and hence it has been removed.
16659 In addition, this patch improves the text of the message.
16660 (Resolve_Type_Conversion): Add missing support for access to interface
16662 (Resolve_Type_Conversion): If the target is a class-wide interface type,
16663 do not expand if the expression is the actual in a call, because proper
16664 expansion will take place when the call itself is expanded.
16665 (Resolve_Allocator): If the context is an unchecked conversion, the
16666 allocator inherits its storage pool, if any, from the target type of
16669 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16670 Javier Miranda <miranda@adacore.com>
16672 * sem_type.adb (Add_One_Interp): If a candidate operation is an
16673 inherited interface operation that has an implementation, use the
16674 implementation to avoid spurious ambiguities.
16675 (Interface_Present_In_Ancestor): In case of concurrent types we can't
16676 use the Corresponding_Record_Typ attribute to look for the interface
16677 because it is set by the expander (and hence it is not always
16678 available). For this reason we traverse the list of interfaces
16679 (available in the parent of the concurrent type).
16680 (Interface_Present_In_Ancestor): Handle entities from the limited view
16682 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16684 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
16685 from the list of required components.
16686 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
16687 primitive procedure of a limited interface with a controlling first
16689 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
16691 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
16692 capture if it is generated in the second operand of a short-circuit
16694 Do not capture values for variables with address clauses.
16695 (Is_Object_Reference): Treat a function call as an object reference only
16696 if its type is not Standard_Void_Type.
16698 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16700 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
16701 to a variable that is statically known to be constant.

16713 Document that bounds of result of Base_Name match the input index
16715 Add documentation on environment variable syntax for Expand_Path
16717 * gnat_ugn.texi: Update documentation to include mention of -m switches
16718 Document new treatment of wide characters in max line length
16720 Remove -gnatL/-gnatZ switches, no longer used.
16721 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
16724 * gnat_rm.texi: Add doc for two argument form of pragma
16725 Float_Representation.
16726 Add documentation for pragma No_Strict_Aliasing
16727 Add note that explicit component clause overrides pragma Pack.
16728 Add documentation of pragma Debug_Policy

17323 * s-mastop-irix.adb (Pop_Frame): Revert shorcuts avoiding calls to
17324 exc_unwind, now that we are generating proper .debug_frame output for
17327 * tracebak.c: Remove the mips-irix section, as we are now using the
17328 s-mastop based unwinder again.
17329 Under SPARC/Solaris, take into account the stack bias to compute the
17330 frame offset. The stack bias is 0 for the V8 ABI and 2047 for the V9

17483 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
17484 longer protected objects. They have been replaced by lower-level
17485 suspension objects made up by a mutex and a condition variable (or
17486 their equivalent given a particular OS) plus some internal data to
17487 reflect the state of the suspension object.
17488 (Initialize, Finalize): Add this initialization procedure for
17489 Suspension_Object, which is a controlled type.
17490 (Finalize): Add the finalization procedure for Suspension_Object,
17491 which is a controlled type.
17493 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
17494 Ada.Synchronous_Task_Control because there is no longer a need for a
17495 VxWorks specific version of this package. Target dependencies
17496 has been moved to System.Task_Primitives.Operations.
17498 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
17500 (InitializeCriticalSection, EnterCriticalSection,
17501 LeaveCriticalSection, DeleteCriticalSection): Replace the type
17502 pCriticalSection by an anonymous access type so that we avoid problems
17503 of accessibility to local objects.
17505 * s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,

17509 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
17510 set the environment task mask here.
17511 (Current_State): Add this function that returns the state of the
17513 (Set_False): Add this procedure that sets the state of the suspension
17515 (Set_True): Add this procedure that sets the state of the suspension
17516 object to True, releasing the task that was suspended, if any.
17517 (Suspend_Until_True): Add this procedure that blocks the calling task
17518 until the state of the object is True. Program_Error is raised if
17519 another task is already waiting on that suspension object.
17520 (Initialize): Add this procedure for initializing the suspension
17521 object. It initializes the mutex and the condition variable which are
17522 used for synchronization and queuing, and it sets the internal state
17524 (Finalize): Add this procedure for finalizing the suspension object,
17525 destroying the mutex and the condition variable.

17530 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
17531 which provides a low-level abstraction (using operating system
17532 primitives) for Ada.Synchronous_Task_Control.
17533 This object is made up by a mutex (for ensuring mutual exclusion), a
17534 condition variable (for queuing threads until the condition is
17535 signaled), a Boolean (State) indicating whether the object is open,
17536 and a Boolean (Waiting) reflecting whether there is a task already
17537 suspended on this object.

17730 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
17731 type is a class-wide type, emit a run-time check that the accessibility

17802 type derivation of private tagged types implementing interfaces.
17803 In this case some interface primitives may have been overriden

17893 * i-cpp.ads, i-cpp.adb:
17894 This package has been left available for compatibility with previous

17933 on subprogram stubs as well.
17934 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
17936 (Analize_Subprogram_Specification): When analyzing a subprogram in which

17939 (Analyze_Subprogram_Body): Undo the previous work.
17940 (Analyze_Procedure_Call): If the call has the form Object.Op, the

17949 access to subprograms must be recursive.
17950 (Is_Unchecked_Conversion): Improve the test that recognizes
17951 instantiations of Unchecked_Conversion, and allows them in bodies that
17952 are to be inlined by the front-end. When the body comes from an
17953 instantiation, a reference to Unchecked_Conversion will be an
17954 Expanded_Name, even though the body has not been analyzed yet.

17975 object or component (that is, when Is_Local_Anonymous_Access is true).
17976 Prevent the special checks for conversions of access discriminants in
17977 the case where the discriminant belongs to a nonlimited type, since
17978 such discriminants have their accessibility level defined in the same
17979 way as a normal component of an anonymous access type.
17980 (Resolve_Allocator): When an allocator's designated type is a class-wide
17981 type, check that the accessibility level of type given in the
17982 allocator's expression or subtype indication is not statically deeper

19010 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
19011 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
19012 analyzed if expansion is disabled (which could otherwise cause spurious
19013 error messages if expansion has been disabled due to previous
19014 (unrelated) errors).
19016 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
19017 is disabled, the entity denoted by the argument is the access type
19018 itself, not an underlying record type, so there is no need to go back
19019 to the Corresponding_Remote_Type.

19029 denotes a type in the class.
19030 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
19031 of Name_Generic_Dispatching_Constructor.
19033 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

19051 a class-wide stream attribute) and then rewrite the attribute name
19052 as the name of the appropriate compiler-generated stream primitive.

19064 itype whose parent is controlled and not yet frozen, do not create a
19065 freeze node for the itype if expansion is disabled.
19067 2005-03-29 Vincent Celier <celier@adacore.com>
19069 * make.adb (Gnatmake): Don't fail if the main project file is declared
19070 as having no Ada sources. Do not display message "no sources to

19091 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
19092 rather than proceed ahead using a junk attribute name.
19094 2005-03-29 Vincent Celier <celier@adacore.com>
19096 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
19098 * prj-part.adb (Parse_Single_Project): Set the location of a project
19099 on its defining identifier, rather than on the reserved word "project".
19101 * prj-proc.adb (Expression): Adapt to the fact that default of external
19102 references may be string expressions, not always literal strings.
19103 (Recursive_Process): Set Display_Name equal to Name
19104 when Location is No_Location, that is when there is no actual file.
19105 Get the Display_Name of the project from the source, when it is not a
19107 (Process): Use the Display_Name in error messages
19109 * prj-strt.adb (External_Reference): Allow default to be string
19110 expressions, not only literal strings.

19123 equivalent type for a remote access-to-subprogram type, go back to the
19124 original RAS entity when displaying an error message, so the casing is
19125 the original source casing.

19134 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
19135 subtype if code is being pre-analyzed, to prevent un-expanded
19136 references to protected formals, among others.
19137 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
19138 interpretation that can be a call, include the result of the call as a
19139 possible interpretation of the dereference.
19141 * sem_ch5.adb (Process_Bounds): Determine type of range by
19142 pre-analyzing a copy of the original range, and then analyze the range
19143 with the expected type.
19145 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
19146 with an overloaded prefix where not all interpretations yield an
19147 access to subprogram, do not rewrite node as a call.
19148 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
19149 the node as a call once the context identifies the interpretation of
19150 the prefix whose call yields the context type.
19151 (Valid_Conversion): For the case of a conversion between
19152 local access-to-subprogram types, check subtype conformance using
19153 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more

19158 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
19159 indicator, indicate that the formal can never be null.
19160 (Process_Formals): If a formal has a non_null indicator, insert the
19161 resulting subtype immediately before the enclosing subprogram decl,
19162 and not at the beginning of the corresponding declarative part, to
19163 prevent access before elaboration (Ada2005).

19287 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
19288 subprogram determines whether a default implementation exists for a
19289 given stream attribute.
19290 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
19291 Determine whether to generate a default implementation for each stream
19292 attribute separately, as this depends on the specific attribute.

19295 limited extension where a stream attribute is missing for a limited
19296 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

19897 expression to the type of the object when the object is constant.
19898 Reverse defer_debug_incomplete_list before traversing it, so that trees
19899 are processed in the order at which they were added to the list. This
19900 order is important when using the stabs debug format.
19901 If we are deferring the output of debug information, also defer this
19902 output for a function return type.
19903 When adding fields to a record, prevent emitting debug information
19904 for incomplete records, emit the information only when the record is
19906 (components_to_record): New parameter defer_debug.
19907 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
19908 (gnat_to_gnu_field_decl): New function.
19909 (substitution_list, annotate_rep): Call it.
19910 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
19911 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
19912 No longer update discriminants to not be a COMPONENT_REF.
19913 (copy_alias_set): Strip padding from input type; also handle
19914 unconstrained arrays properly.
19916 * gigi.h (write_record_type_debug_info): New function.
19917 Convert to use ANSI-style prototypes. Remove unused
19918 declarations for emit_stack_check, elab_all_gnat and
19919 set_second_error_entity.
19920 (gnat_to_gnu_field_decl): New decl.
19922 * utils.c (write_record_type_debug_info): New function.
19923 (finish_record_type): Delegate generation of debug information to
19924 write_record_type_debug_info.
19925 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
19926 (update_pointer_to): Fix pasto.
19927 (convert) <UNION_TYPE>: Accept slight type variations when
19928 converting to an unchecked union type.
19930 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
19931 replace the N_Freeze_Entity with a null statement.
19933 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
19934 within a constrained subcomponent of an enclosing record, place the
19935 freeze nodes in the scope stack entry for the enclosing record.
19936 (Undelay_Type): New Subprogram.
19937 (Set_Small_Size): Pass T, the type to modify; all callers changed.
19938 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
19939 within records; allow them to have freeze nodes if their base types
19942 * exp_util.adb (Remove_Side_Effects): Properly test for
19943 Expansion_Delayed and handle case when it's inside an
19944 N_Qualified_Expression.
19946 * sem_ch3.adb (Derived_Type_Declaration): New predicate
19947 Comes_From_Generic, to recognize accurately that the parent type in a
19948 derived type declaration can be traced back to a formal type, because
19949 it is one or is derived from one, or because its completion is derived
19951 (Constrain_Component_Type): If component comes from source and has no
19952 explicit constraint, no need to constrain in in a subtype of the
19954 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
19955 Minor change to propagate Is_Ada_2005 flag
19957 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
19958 Expansion_Delayed is False.
19959 (assoc_to_constructor): Ignore fields that have a
19960 Corresponding_Discriminant.
19961 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
19962 function returns "by target", dereference the target pointer using the
19963 type of the actual return value.
19964 <all>: Be prepared for a null gnu_result.
19965 (processed_inline_subprograms): Check flag_really_no_inline
19966 instead of flag_no_inline.
19967 (set_second_error_entity): Remove unused function.
19968 (gnat_to_gnu, case N_Selected_Component): Call
19969 gnat_to_gnu_field_decl.
19970 (assoc_to_constructor): Likewise.
19972 2005-03-15 Robert Dewar <dewar@adacore.com>
19973 Ed Schonberg <schonberg@adacore.com>
19974 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
19976 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
19977 Must_Be_Byte_Aligned for cases where we do not need to use a
19978 System.Pack_nn unit.
19980 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
19982 Needed now that we do some processing for IN parameters as well. This
19983 may well fix some unrelated errors.
19984 (Expand_Call): Handle case of unaligned objects (in particular those
19985 that come from packed arrays).
19986 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
19987 renamed entity is an inherited operation, re-expand the call using the
19988 original operation, which is the one to call.
19989 Detect attempt to inline parameterless recursive subprogram.
19990 (Represented_As_Scalar): Fix to work properly with private types
19991 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
19992 accurate estimate. Yields True in far fewer cases than before,
19993 improving the quality of code that depends on this test.
19995 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
19996 over both visible and private declarations to remove them from tree,
19997 and mark subprograms declared in package as eliminated, to prevent
19998 spurious use in subsequent compilation of generic units in the context.
20000 * exp_util.ads: Minor cleanup in variable names
20002 * sem_eval.ads, sem_eval.adb: Minor reformatting
20003 (Compile_Time_Known_Bounds): New function
20005 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20007 * exp_ch7.adb (Convert_View): Use base types of underlying types when
20008 determining whether an unchecked conversion is needed for the argument
20009 of an initialization call.
20011 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20013 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
20014 that appears in the instantiation rather than the internal subtype
20015 generated in the wrapper package, to avoid anomalies in gigi when the
20016 target is derived from a private type whose full view is an access type.
20018 2005-03-15 Robert Dewar <dewar@adacore.com>
20020 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
20022 Add documentation to replace the use of this flag
20023 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
20026 2005-03-15 Thomas Quinot <quinot@adacore.com>
20028 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
20029 here from exp_attr so it can be shared between exp_attr and exp_dist.
20030 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
20031 all TSS names, not a subset thereof, and the previous name introduced
20032 an unnecessarily confusion that a distinction might exist between
20033 "OK" TSS names and some "not OK" TSS names.
20035 2005-03-15 Doug Rupp <rupp@adacore.com>
20037 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
20040 2005-03-15 Pascal Obry <obry@adacore.com>
20041 Eric Botcazou <ebotcazou@adacore.com>
20045 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
20046 when IN_RTS. This is to work around a bootstrap path problem.
20048 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
20049 table and pass it to __gnat_install_SEH_handler().
20050 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
20052 * lang.opt: Fix specification of -fRTS=.
20054 2005-03-15 Doug Rupp <rupp@adacore.com>
20055 Bernard Banner <banner@adacore.com>
20056 Vincent Celier <celier@adacore.com>
20057 Arnaud Charlet <charlet@adacore.com>
20060 This change works fine when gnatlib is built from the gcc directory,
20061 but does not work when using the libada Makefile, since GCC_FOR_TARGET
20062 is not passed to ada/Makefile.in, so more work is needed by a
20063 Makefile/configure expert.
20065 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
20066 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
20067 Setup gnatlink switch -M for x86_64 linux, as it is already setup
20069 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
20070 Run ranlib on libgccprefix.a
20071 Define PREFIX_OBJS for Darwin, to build libgccprefix.
20072 (ADA_INCLUDE_SRCS): Split Ada packages.
20074 2005-03-15 Robert Dewar <dewar@adacore.com>
20076 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
20078 * impunit.adb: Add GNAT.UTF_32
20080 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
20082 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
20083 now uses GNAT.UTF_32).
20085 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
20086 capabilities for categorizing characters using Unicode categories
20088 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20090 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
20091 instantiation that has been rewritten as a package body, retrieve spec
20092 to generate proper name for implicit_with_clause.
20093 (Install_Parents): Recognize a parent that is an instantiation but has
20094 been rewritten as a package declaration during analysis.
20096 2005-03-15 Javier Miranda <miranda@adacore.com>
20097 Ed Schonberg <schonberg@adacore.com>
20099 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
20100 parameter reported some error we immediately return. This improves the
20101 behaviour of the frontend in case of errors.
20102 (Install_Parent, Remove_Parent): Introduce new flag
20103 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
20104 ancestor of a generic child unit, when the child is being instantiated.
20105 (Inline_Instance_Body): If we are compiling the private
20106 part or the body of a child unit, restore the proper visibility of the
20107 parents after compiling the instance body.
20109 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20110 Javier Miranda <miranda@adacore.com>
20113 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
20114 of a private type, in which case it is underlying_type that denotes
20115 the proper task. Also modified to use the new entity attribute
20116 that is directly available in the task type and task subtype entities
20117 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
20118 arrays when other dimensions than the first are constrained by
20119 discriminants of an enclosing record.
20120 (Insert_Explicit_Dereference): If the prefix is an indexed component or
20121 a combination of indexed and selected components, find ultimate entity
20122 and generate the appropriate reference for it, to suppress spurious
20124 (Note_Possible_Modification): If an entity name has no entity, return.
20125 (Is_Variable): A function call never denotes a variable.
20126 (Requires_Transient_Scope): For record types, recurse only on
20127 components, not on internal subtypes that may have been generated for
20128 constrained components.
20130 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20132 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
20133 Eliminated as candidates for resolution. Both efficient, and avoids
20134 anomalies with operators declared in deleted code.
20135 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
20136 expansion is disabled (as when compiling a generic) to prevent spurious
20137 warnings on prefixes of selected components.
20139 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20141 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
20142 attached to a list before checking whether it appears in the private
20143 declarations of the current package.
20144 (Make_Inequality_Operator): Insert declaration in proper declarative
20145 list rather than just setting the Parent field, so that
20146 Is_Private_Declaration can handle it properly.
20148 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20150 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
20151 a renaming a body, check that the renamed subprogram in not intrinsic.
20152 (Find_Direct_Name): If several use_visible entities hide
20153 each other, and the context is a predefined file compiled through
20154 rtsfind, keep only the entity that comes from a predefined file.
20156 2005-03-15 Geert Bosch <bosch@adacore.com>
20158 * s-fatgen.adb (Valid): Extend special exceptions to account for long
20159 long float padding to also cover AMD64 and IA64.
20161 2005-03-15 Gary Dismukes <dismukes@adacore.com>
20163 * s-imgwch.adb: Add with and use of Interfaces.
20164 (Img_Wide_Character): Change type of Val to Unsigned_16.
20165 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
20167 2005-03-15 Matthew Gingell <gingell@adacore.com>

20203 procedures in the bug boxes for various GNAT builds.
20205 2005-03-15 Vincent Celier <celier@adacore.com>
20207 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

20212 Cyrille Comar <comar@adacore.com>
20213 Sergey Rybin <rybin@adacore.com>
20215 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
20216 too specific and long-winded to be appropriate for the GNAT User's
20218 Warn about use of GCC switches not documented in the GNAT User's Guide,
20219 as these may cause generated code to not conform to Ada semantics.
20220 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
20221 Add documentation for -gnat95 and -gnat05 switches
20222 Remove paragraph documenting obsolete way to refer to third party

20347 * exp_ch3.ads, exp_ch3.adb: Fix various places where Wide_Wide_String
20348 was not taken into account.
20349 This includes proper initialization with Normalize_Scalars.
20350 (Get_Simple_Init_Val): Major rewrite for initialize scalars and
20351 normalize scalars cases (particularly the latter) to do a better job
20352 of finding invalid representations.
20354 * s-scaval.ads, s-scaval.adb: Add values for zero invalid values
20356 * s-strops.ads, s-strops.adb: Remove string normalize routines, never
20359 * exp_dist.adb: Add support for wide wide character type
20360 (Expand_Receiving_Stubs_Bodies): For a package declaration that has a

20498 value by a warning message.
20499 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted

20641 the formal subprogram.
20642 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
20643 which is an unclean use of that field, we set the new field

20662 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
20663 mark in function specification, in a context where the formals are
20664 visible and hide outer homographs.
20666 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
20667 as the tagged type for the cases of abstract formal subprograms and
20668 renamings of those. Clean up spec comments.

20670 procedure", covering the case of a call to a formal abstract procedure
20671 that has statically tagged operands.
20672 (Check_Dispatching_Call): Check for the case of an actual given by
20673 a tag-indeterminate function call whose type is an ancestor of the
20674 containing call's associated tagged type. This situation can occur
20675 for inherited primitives with function defaults. In this case we
20676 use the tagged type's tag directly as the controlling argument for

20869 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
20870 with expansion disabled. The actual subtype is needed among other
20871 places when the selected component appears in the context of a loop
20872 bound, and denotes a packed array.
20873 (Operator_Check): Always use the first subtype in the
20874 error message, to avoid the appearance of internal base types.
20875 (Transform_Object_Operation): Copy each actual in full
20876 to the parameter associations of the constructed call, rather than
20877 using the shallow copy mechanism of New_Copy_List. This ensures that
20878 the chaining of named associations is done properly.
20879 (Complete_Object_Operation): Rewrite node, rather than
20880 replacing it, so that we can trace back to the original selected
20883 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
20884 and calls that use object notation, if the called function is not
20885 declared in a withed unit, place the elaboration constraint on the
20886 unit in the context that makes the function accessible.
20887 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
20888 imposes an elaboration constraint between two packages.
20890 2005-02-09 Ed Schonberg <schonberg@adacore.com>
20892 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
20893 views of a private type after handling its private dependents, to
20894 maintain proper stack discipline between entry and exit from the

20915 Slight fix to documentation of -gnaty with no parameters
20917 * xr_tabls.ads: Add ??? comment for missing overall comment
20919 * xsinfo.adb: Make default file name be sinfo.h, since this is what
20920 we now use by default.
20922 * xsnames.adb: Adjust end of file test to look for five space followed
20923 by '#' instead of six spaces. The format of xsnames.adb was modified
20924 in the last update.
20926 * a-numeri.ads: Add reference to AI-388 for greek letter pi
20929 * clean.adb: Minor reformatting.
20931 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
20932 gnatname.adb: Minor reformatting
20933 Add 2005 to copyright output when utility is run
20935 * csets.adb: Eliminate obsolete comment
20937 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
20940 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
20942 2005-02-09 Sergey Rybin <rybin@adacore.com>
20944 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
20945 the difference between compact and incompact layout and add the record
20946 representation clause to the example illustrating different layouts.
20947 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
20948 component clauses").
20950 2005-02-09 Florian Villoing <villoing@adacore.com>
20952 * gnat_ugn.texi: Fix typos.
20953 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
20955 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
20956 in the generated documentation.
20958 2005-02-09 Arnaud Charlet <charlet@adacore.com>
20960 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
20962 Update linker wrapper when linking with non GNU C++.
20964 2005-02-09 Pascal Obry <obry@adacore.com>

21000 * exp_util.ads: Minor correction in comment.
21002 2005-02-09 Arnaud Charlet <charlet@adacore.com>
21004 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
21005 since this procedure is now too complex to be worth inlining.

21252 2005-01-03 Olivier Hainque <hainque@adacore.com>
21254 * decl.c (compatible_signatures_p): New function. The intended purpose
21255 is to check if two function signatures for a call-site and a callee are
21256 compatible enough for the call to be valid. The underlying purpose is
21257 to check if a call to a mapped builtin is using the right interface.
21258 The current code actually does not check antyhing - this a placeholder
21259 for future refinements.

21308 variants of the PCS.
21309 Reorganise RPC receiver generation to reduce differences between the
21310 structure of GARLIC and PolyORB RPC receivers.
21311 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
21313 Simplify elaboration code for RCI packages.
21315 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver
21316 generation to reduce differences between the structure of GARLIC and

21673 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
21674 with an implicit dereference as its prefix, use

21677 prefix is generated, if appropriate.
21679 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
21680 dereference is rewritten to an explicit one, generate a reference to

21683 access value, if appropriate.
21685 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from

21797 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
21798 used to record an implicit dereference as a read operation on its
21799 prefix when operating under -gnatc. Necessary to avoid spurious
21800 'variable assigned but never read' warnings in that mode.
21801 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
21802 is a non-overloaded implicit dereference, call the above subprogram to
21803 ensure proper recording of references.
21805 2004-12-07 Gary Dismukes <dismukes@adacore.com>

21850 Reformatting to suppress most of the warnings for line too long
21851 Document the new section "Project Search Path:" in the output of
21853 Add gnatmetric section
21855 2004-12-07 Vincent Celier <celier@adacore.com>
21857 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
21858 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
21859 and -eit to -ept. Added qualifier
21860 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
21862 2004-11-27 Andreas Schwab <schwab@suse.de>
21864 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
21866 2004-11-25 Arnaud Charlet <charlet@adacore.com>
21868 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
21869 internal implementation unit GNAT.Sockets.Thin,
21870 as their usage for sockets is non-portable (using the read and write
21871 functions from the system runtime library is fine on UNIX but won't
21872 work under Windows).
21874 * mingw32.h: Update copyright notice.
21876 2004-11-25 Arnaud Charlet <charlet@adacore.com>
21878 * ada-tree.h: Minor reformatting of previous change to avoid lines
21879 longer than 79 characters.
21881 2004-11-25 Olivier Hainque <hainque@adacore.com>
21883 * tb-gcc.c: GCC infrastructure based implementation of

21897 2004-11-21 Andreas Jaeger <aj@suse.de>
21899 * stylesw.adb: Change Style_Check_Subprogram_Order to
21900 Style_Check_Order_Subprograms.
21902 2004-11-18 Arnaud Charlet <charlet@adacore.com>
21904 * adaint.h, adaint.c
21905 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
21907 Add also a cast to kill another warning.
21908 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
21909 parameter with the priority class of the parent process instead of
21910 always using the NORMAL_PRIORITY_CLASS.
21911 (__gnat_dup): New function.
21912 (__gnat_dup2): New function.
21913 (__gnat_is_symbolic_link): Enable the effective body of this
21914 function when __APPLE__ is defined.
21916 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
21919 2004-11-18 Olivier Hainque <hainque@adacore.com>
21921 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
21922 address of which may be used to represent "others" and "all others"
21923 choices in exception tables, instead of the current harcoded
21924 (void *)0 and (void *)1.
21925 (Setup_Exception): Do nothing in the GNAT SJLJ case.
21927 * gigi.h (others_decl, all_others_decl): New decls representing the
21928 new Others_Value and All_Others_Value objects.
21929 (struct attrib): Rename "arg" component as "args", since GCC expects a
21930 list of arguments in there.
21932 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
21933 corresponding objects exported by a-exexpr, instead of hardcoded dummy
21936 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
21937 others_decl and all_others_decl instead of hardcoded dummy addresses
21938 to represent "others" and "all others" choices, which is cleaner and
21939 more flexible with respect to the possible eh pointer encoding policies.
21941 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
21942 (process_attributes): Account for the naming change of the "args"
21943 attribute list entry component.
21945 * decl.c (build_attr_list): Rename into prepend_attributes to allow
21946 cumulating attributes for different entities into a single list.
21947 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
21948 attributes for the current entity and propagate first subtype
21949 attributes to other subtypes.
21950 <E_Procedure>: Attribute arguments are attr->args and not
21951 attr->arg any more.
21952 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
21953 argument provided, as this is what GCC expects. Use NULL_TREE instead
21956 2004-11-18 Robert Dewar <dewar@adacore.com>
21958 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
21959 Minor reformatting througout (including new function specs)
21960 Add ??? comments asking for clarification.
21962 2004-11-18 Thomas Quinot <quinot@adacore.com>
21964 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
21965 incomplete duplicate implementation of this subprogram from butil.
21967 2004-11-18 Thomas Quinot <quinot@adacore.com>
21969 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
21970 procedures factors the common processing for building an RPC receiver
21971 for an RCI package or an RACW type.
21972 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
21973 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
21974 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
21976 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
21978 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
21980 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
21981 distribution subprogram identifiers that are either subprogram numbers
21983 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
21984 string distribution identifiers assigned to a given subprogram.
21985 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
21986 (Add_RAS_Dereference_TSS): Add comments.
21987 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
21988 is not referenced yet because it will be used by the PolyORB DSA
21990 (Insert_Partition_Check): Remove fossile code.
21991 (First_RCI_Subprogram_Id): Document this constant.
21992 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
21994 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
21995 replaced with calls to Get_Library_Unit_Name_String. Previously there
21996 were several instances of the same code in different locations in the
21997 compiler; this checkin completes the replacement of all of these
21998 instances with calls to a common subprogram.
21999 Minor reformatting.
22001 * sem_dist.adb: Remove comment noting that RPC receiver generation
22002 should be disabled for RACWs that implement RASs.
22003 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
22005 * sem_util.ads, sem_util.adb (Has_Stream): New function
22006 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
22007 qualified name of a library unit into the name buffer.
22008 (Note_Possible_Modification): Generate a reference only
22009 if the context comes from source.
22011 * snames.ads (PCS_Names): New subtype corresponding to names of
22012 supported implementations of the Partition Communication Subsystem
22013 (PCS) (i.e. the runtime library support modules for the distributed
22016 2004-11-18 Robert Dewar <dewar@adacore.com>
22017 Ed Schonberg <schonberg@adacore.com>
22019 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
22020 (Has_Rep_Pragma): New function
22021 (Has_Attribute_Definition_Clause): New function

22023 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
22025 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
22027 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
22028 (Expand_Pragma_Psect_Object): New procedure
22029 These procedures contain the revised and cleaned up processing for
22030 these two pragmas. This processing was formerly in Sem_Prag, but
22031 is more appropriately moved here. The cleanup involves making sure
22032 that the pragmas are properly attached to the tree, and that no
22033 nodes are improperly shared.
22035 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
22036 pragmas to Exp_Prag, which is more appropriate.
22037 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
22038 check for duplicates Remove use of Is_Psected flag, no longer needed.
22039 Use new Make_String_Literal function with string.
22041 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
22042 that are functions return universal values, that have to be converted
22043 to the context type.
22044 Use new Make_String_Literal function with string.
22045 (Get_Stream_Convert_Pragma): New function, replaces the use of
22046 Get_Rep_Pragma, which had to be kludged to work in this case.
22048 * freeze.adb: Use new Has_Rep_Pragma function
22050 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
22051 function with string.
22052 Use new Has_Rep_Pragma function.
22054 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
22057 2004-11-18 Robert Dewar <dewar@adacore.com>
22059 * errout.ads, errout.adb: (First_Sloc): New function
22061 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
22062 check (-gnatyx) instead of being included as a redundant construct
22065 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
22066 Style_Check_Order_Subprograms.
22068 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
22069 stylesw.adb: Add Style_Check_Xtra_Parens
22071 * usage.adb: Add line for -gnatyx (check extra parens)
22073 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
22075 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22076 Robert Dewar <dewar@adacore.com>
22078 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
22079 discriminant of a constrained subtype, analyze the copy of the
22080 corresponding constraint, because in some cases it may be only
22081 partially analyzed.
22082 Removes long-lived ??? comments.
22084 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
22085 handled controlled or secondary-stack expressions within the
22086 iteration_scheme of a loop.
22088 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
22089 bounds that may contain functions calls, to prevent memory leaks when
22090 the bound contains a call to a function that uses the secondary stack.
22091 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
22092 generate temporaries for loop bounds that might contain function calls
22093 that require secondary stack and/or finalization actions.
22095 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
22096 selected component and the selector is overloadable (not just a
22097 function) treat as function call, Analyze_Call will disambiguate if
22099 (Analyze_Selected_Component): Do not generate an actual subtype for the
22100 selected component if expansion is disabled. The actual subtype is only
22101 needed for constraint checks.
22102 (Analyze_Allocator): If restriction No_Streams is set, then do
22103 not permit objects to be declared of a stream type, or of a
22104 composite type containing a stream.
22106 * restrict.ads: Remove the a-stream entry from Unit_Array, since
22107 No_Streams no longer prohibits with'ing this package.
22109 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
22110 discriminants, but the parent base has unknown discriminants, there is
22111 no discriminant constraint to inherit. Such a discrepancy can arise
22112 when the actual for a formal type with unknown discriminants is a
22113 similar private type whose full view has discriminants.
22114 (Analyze_Object_Declaration): If restriction No_Streams is set, then
22115 do not permit objects to be declared of a stream type, or of a
22116 composite type containing a stream.
22118 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22120 * exp_dbug.ads: Update documentation to reflect simpler encoding for
22121 protected operations.
22123 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
22124 generated name, it complicates decoding in gdb and hinders debugging
22125 of protected operations.
22126 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
22127 flag for the protected entry barrier function.
22128 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
22129 flag for the protected entry function.

22133 * expect.c: Define __unix__ when __APPLE__ is defined.
22135 * Makefile.in: Inform the value of the variable GMEM_LIB in the
22136 Darwin-specific section.
22138 * lang-specs.h: Change the placement of the %1 marker.
22139 Works around the fact that gcc adds -fPIC by default under Darwin.
22141 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22143 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
22144 type of the object with the packed array type, set the Analyzed flag
22145 on the object if it is an entity or simple indexed component, to avoid
22146 spurious type errors.
22148 2004-11-18 Gary Dismukes <dismukes@adacore.com>
22150 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
22151 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
22152 separate line from the version message.
22154 2004-11-18 Ed Falis <falis@adacore.com>
22156 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
22158 (init_float): Eliminate initialization of floating point status for
22159 AE653. The instructions have no effect for vThreads.
22161 2004-11-18 Vincent Celier <celier@adacore.com>
22163 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
22164 gnatbind is invoked with -shared.
22166 2004-11-18 Jose Ruiz <ruiz@adacore.com>
22168 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
22169 for Detect_Blocking which is redundant with the check done within the
22170 procedure Protected_Single_Entry_Call.
22171 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
22172 Detect_Blocking which is redundant with the check done within the
22173 procedure Protected_Single_Entry_Call.
22175 2004-11-18 Vincent Celier <celier@adacore.com>
22177 * makegpr.adb (Compile): Put the compiling switches (in package
22178 Compiler and on the command line) immediately after "-c", instead of
22179 at the end of the command line invocation of the compiler, when
22180 compiling a non-Ada file.
22181 (Build_Global_Archive): When there is no need to rebuild the archive,
22182 set Global_Archive_Exists, so that the archive is passed to the linker
22185 2004-11-18 Robert Dewar <dewar@adacore.com>
22186 Sergey Rybin <rybin@adacore.com>
22189 Remove extra paren check from list of checks for redundant constructs
22190 Add documentation of new -gnatyx style check (check extra parens)
22191 Remove paragraph about gnatelim debug options.
22193 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
22194 objects rather than forbidding dependencies on the package Ada.Streams.
22196 * sinfo.ads: Add ??? note that we should document pragmas passed to
22199 * g-expect.ads: Fix a few typos in the comments.
22201 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
22203 * misc.c (gnat_handle_option): Use %< and %> for quoting in
22206 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
22208 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
22210 2004-11-07 Andreas Schwab <schwab@suse.de>
22212 * Makefile.in (install-gnatlib): Remove spurious hyphen.
22214 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
22217 * Makefile.in (darwin): Set soext to .dylib.
22219 2004-10-26 Vincent Celier <celier@gnat.com>
22220 Thomas Quinot <quinot@act-europe.fr>
22222 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
22223 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
22224 there is no use of GNAT.Sockets.Constants.
22225 Remove remaining pragma Import for C_Write
22226 Remove C_Read and C_Write from internal implementation unit
22227 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
22228 the read and write functions from the system runtime library is fine
22229 on UNIX but won't work under Windows).
22231 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
22232 (Check_Selector): Use C_Recv instead of C_Read.
22233 Selectors are the GNAT.Sockets abstraction to perform a select()
22234 call on a set of descriptors. To allow abortion of an ongoing
22235 select operation, some data is written to a dedicated socket that
22236 is always monitored.
22237 Under Windows, the write and read library functions cannot operate
22238 on sockets, so we need to use send and recv instead, which is portable
22239 across all supported platforms.
22241 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
22242 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
22243 (using the read and write functions from the system runtime library is
22244 fine on UNIX but won't work under Windows).
22246 2004-10-26 Nicolas Setton <setton@act-europe.fr>
22248 * mlib-tgt-darwin.adb: New file.
22250 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
22251 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
22252 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
22253 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
22256 * Makefile.in: Add support for building shared libraries under Darwin.
22257 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
22258 the low level EH init subprogram to be called from __gnat_initialize.
22260 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
22261 indicates which options to pass to the archive indexer.
22263 * mlib-utl.adb: Add support for calling ranlib with additional
22264 options. This is needed for instance under Mac OS X.
22265 (Ranlib_Options): New global variable, used to store the potential
22266 options to pass to ranlib.
22267 (Ar): Use Ranlib_Options when spawning ranlib.
22268 (Initialize): Set the value of ranlib option.
22270 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22272 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
22273 instead of 8K, to reflect the real potential needs for stack-checking
22276 2004-10-26 Pascal Obry <obry@gnat.com>
22278 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
22280 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
22281 Windows only the initial thread stack size can be set so it is good to
22282 start we a low stack size.
22283 The OS will adjust the size as needed.
22285 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22286 Nicolas Setton <setton@act-europe.fr>
22288 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
22289 "__unix__" instead of "unix".
22290 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
22291 sections were just mistakenly ignored. The former is
22292 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
22293 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
22294 of hpux. This prevents an unwanted definition of the symbol
22295 convert_addresses in adaint.o.
22297 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22299 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
22300 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
22302 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22304 * a-filico.ads, a-filico.adb: fix incorrect header.
22306 2004-10-26 Javier Miranda <miranda@gnat.com>
22308 * a-ststio.ads: Fix typo in identifier
22310 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22312 * sem_ch4.adb: Minor reformatting.
22314 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22316 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
22317 enabled, check the result of unary and binary operations when the
22318 expression is the right-hand side of an assignment.
22320 2004-10-26 Vincent Celier <celier@gnat.com>
22322 * clean.adb (Delete): Do not output warnings when in quiet output and
22323 not in verbose mode.
22324 (Force_Deletions): New Boolean flag, defaulted to False
22325 (Delete): Only delete a file if it is writable, and when
22326 Force_Deletions is True.
22327 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
22328 (Usage): Line for new switch -f
22329 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
22332 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22334 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
22335 JM type only if its size matches that of the wrapper. When a size is
22336 prescribed and the field is not aliased, remove the wrapper of a JM
22337 type only if the size is not greater than that of the packed array.
22338 (gnat_to_gnu_entity): Change the extension of packed array wrappers
22341 2004-10-26 Geert Bosch <bosch@gnat.com>
22343 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
22344 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
22345 (Pred): Implement in terms of Succ.
22347 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22349 * exp_aggr.adb (Safe_Component): An aggregate component that is an
22350 unchecked conversion is safe for in-place use if the expression of the
22351 conversion is safe.
22352 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
22353 be expandable in place even if the aggregate does not come from source.
22354 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
22355 designated object of an allocator in place, rather than building it
22356 first on the stack. The previous scheme forces a full copy of the array,
22357 and may be altogether unsusable if the size of the array is too large
22358 for stack allocation.
22360 2004-10-26 Robert Dewar <dewar@gnat.com>
22362 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
22363 compares if the component is atomic.
22365 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
22366 array assignment if the component type is atomic.
22368 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22369 Eric Botcazou <ebotcazou@act-europe.fr>
22371 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
22372 is aliased and is a by_reference type, do not pass by copy.
22373 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
22374 detect whether the call is in the right side of an assignment or
22375 the expression of an object declaration. Recurse on component
22376 association within aggregates.
22377 Call it in the condition that determines whether the temporary is
22378 necessary for correct stack-checking.
22380 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22382 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
22383 RACW_Type, used in the PolyORB version.
22384 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
22385 version and the GARLIC version.
22387 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
22388 Rename RCI_Info to RCI_Locator for better consistency between the
22389 GARLIC and PolyORB versions of the distributed systems annex.
22390 (DSA_Implementation_Name): This enumeration lists the possible
22391 implementations of the Partition Communication Subsystem for the
22392 Distributed Systems Annex (DSA). The three available implementations
22393 are the dummy stub implementation (No_DSA), and two versions based on
22394 two different distribution runtime libraries: GARLIC and PolyORB. Both
22395 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
22397 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
22400 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
22401 between the GARLIC and PolyORB versions of the distributed systems
22403 Remove RE_Unbounded_Reclaim_Pool since it is unused.
22405 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22407 * gnat1drv.adb: Suppress calling the back end when
22408 Frontend_Layout_On_Target is true.
22410 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22412 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
22413 Set_Read_Only): New subprograms.
22414 These new routines allow the user to set or unset the Owner execute
22415 and Owner write permission flags on a file.
22417 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
22418 GNAT.OS_Lib.Set_Executable instead of rolling our own.
22420 2004-10-26 Matthew Gingell <gingell@gnat.com>
22422 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
22424 2004-10-26 Pascal Obry <obry@gnat.com>
22426 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
22427 memory before the faulting page we properly test the process read
22428 access for this address using appropriate Win32 routine.
22429 (HPUX sections): guard with "__hpux__" instead of "hpux".
22431 2004-10-26 Robert Dewar <dewar@gnat.com>
22433 * lib-xref.adb (Generate_Reference): Don't complain about reference to
22434 entry parameter if pragma Unreferenced set, since we do not properly
22435 handle the case of multiple parameters.
22437 2004-10-26 Vincent Celier <celier@gnat.com>
22439 * prj-env.adb: (Contains_ALI_Files): New Boolean function
22440 (Ada_Objects_Path.Add): For a library project, add to the object path
22441 the library directory only if there is no object directory or if the
22442 library directory contains ALI files.
22443 (Set_Ada_Paths.Add.Recursive_Add): Ditto
22445 2004-10-26 Vincent Celier <celier@gnat.com>
22447 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
22448 extension of library projects.
22450 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
22451 path defaults to ".:<prefix>/lib/gnat".
22452 (Parse): For an extending all project, allow direct import of a project
22453 that is virtually extended.
22455 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
22456 the specified name is directly imported, return its ID. Otherwise, if
22457 an extension of this project is imported, return the ID of the
22460 2004-10-26 Robert Dewar <dewar@gnat.com>
22462 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
22463 (Sub3): New procedure, used by Scaled_Divide
22464 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
22465 correct more than one instance of failure to propagate carries
22467 (Double_Divide): Handle overflow case of largest negative number
22468 divided by minus one.
22470 * s-arit64.ads (Double_Divide): Document that overflow can occur in
22471 the case of a quotient value out of range.
22474 2004-10-26 Robert Dewar <dewar@gnat.com>
22476 * s-bitops.adb (Bit_Eq): Remove redundant check.
22478 * s-bitops.ads: Minor comment updates
22479 Change some occurrences of Address to System.Address
22481 * s-carsi8.ads: Fix minor cut-and-paste error in comments
22483 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22485 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
22486 accessibility check to prefix that is a protected operation.
22488 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22490 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
22491 empty, post message on stub.
22493 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22494 Javier Miranda <miranda@gnat.com>
22496 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
22497 current instance appears within a unit that is directly in the context
22499 Used to determine whether the body of the instance should be analyzed
22500 immediately after its spec, to make its subprogram bodies available
22501 for front-end inlining.
22502 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
22503 constraint is not allowed on the component type (AARM 12.5.3(3))
22505 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22507 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
22508 'Storage_Pool): enhance, document & limit detection of non-sharable
22511 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
22513 * s-pooglo.ads: Add more documentation now that this pool is properly
22516 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22518 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
22519 or protected type with discriminants, do not constrain the
22520 corresponding record type if the subtype declaration has no
22521 discriminant constraints. This can be the case in source code, or in
22522 the subtype declaration created to rename an actual type within an
22525 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22527 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
22528 different kind of stub (possibly wrong name for file), do not check
22530 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
22531 includes call to some function that returns an unconstrained type, do
22534 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22536 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
22537 appear in the code for the main unit. Dependencies among units in the
22538 context of the main unit are established when those other units are
22539 compiled. Otherwise spurious elaboration constraints can generate
22540 incorrect elaboration circularities.
22542 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22543 Ed Schonberg <schonberg@gnat.com>
22545 * sem_util.adb (Is_Aliased_View): Defend against the case where this
22546 subprogram is called with a parameter that is not an object name. This
22547 situation arises for some cases of illegal code, which is diagnosed
22548 later, and in this case it is wrong to call Is_Aliased, as that might
22549 cause a compiler crash.
22550 (Explain_Limited_Type): Refine previous fix to include
22551 inherited components of derived types, to provide complete information.
22553 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
22554 is the prival for a protected object.
22555 It is necessary to mark this entity as a variable, in addition to
22556 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
22557 modified to avoid checking the Aliased flag on entities that are not
22558 objects. (Checking that flag for non-objects is erroneous and could
22559 lead to a compiler crash).
22561 2004-10-26 Robert Dewar <dewar@gnat.com>
22563 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
22564 X_Frac = 0.5, then we know that the number X must be positive.
22565 (Succ): Remove the same redundant test, and also fix the primary test
22566 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
22568 (Decompose): Add fuller comments to spec
22570 2004-10-26 Pascal Obry <obry@gnat.com>
22572 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
22573 validity (process must have read access). Set to 0 in all other cases.
22574 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
22575 violation on Win32.
22576 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
22577 segmentation violation.
22579 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22581 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
22582 whose type is a constructed subtype of an aliased object with an
22583 unconstrained nominal subtype, convert the actual to the constructed
22584 subtype before taking its address.
22586 2004-10-26 Vincent Celier <celier@gnat.com>
22588 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
22589 (Is_Path_Name_Case_Sensitive): New function
22591 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
22592 (Base_Name, Simple_Name, Current_Directory, Compose,
22593 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
22596 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22597 Vasiliy Fofanov <fofanov@act-europe.fr>
22598 Vincent Celier <celier@gnat.com>
22600 * gnat_ugn.texi: Generalize "finding memory problems" section into a
22601 "memory management issues" section and document some of the useful
22602 memory pools provided as part of the GNAT library.
22603 Remove "virtual" from declaration of A::method2 in
22604 the simple example of Ada/C++ mixed system.
22605 Library Projects may be virtually extended: their virtual extensions
22606 are not Library Projects.
22607 Added section on extending project hierarchies.
22609 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
22611 * adaint.c (__gnat_get_libraries_from_registry): Cast value
22613 (__gnat_portable_spawn): Remove const.
22615 * mingw32.h (MAXPATHLEN): Check for previous definition.
22617 2004-10-17 Matthias Klose <doko@debian.org>
22619 * gnatvsn.ads: Set gnat library version to 4.0.
22621 2004-10-05 Vincent Celier <celier@gnat.com>
22623 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
22625 2004-10-04 Laurent GUERBY <laurent@guerby.net>
22628 * Makefile.in: Define and use RANLIB_FLAGS.
22630 2004-10-04 Pascal Obry <obry@gnat.com>
22632 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
22633 other x86 platforms).
22635 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
22637 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
22638 in general and triggers stack alignment adjustment for thread entry
22639 points on targets where this is necessary.
22641 2004-10-04 Bernard Banner <banner@gnat.com>
22644 * Makefile.in: Add section for powerpc linux
22645 Add variant i-vxwork-x86.ads
22647 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
22649 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
22651 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
22652 table registration calls when need be. Ensures no reference to the crt
22653 ctors symbol are issued in the SJLJ case, which avoids possible
22654 undefined symbol errors in the case of modules to be statically linked
22657 2004-10-04 Javier Miranda <miranda@gnat.com>
22659 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
22660 in-line the code corresponding to subprogram Analyze_Actuals. In
22661 addition, analyze the actuals only in case of subprogram call.
22663 2004-10-04 Ed Falis <falis@gnat.com>
22665 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
22667 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
22669 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
22670 in the documentation.
22672 2004-10-04 Robert Dewar <dewar@gnat.com>
22674 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
22676 (Analyze_Block_Statement): Add circuitry to detect following dead code
22677 (Check_Unreachable_Code): Handle case of block exit
22679 2004-10-04 Robert Dewar <dewar@gnat.com>
22681 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
22682 (XMatchD): Avoid warning for Logic_Error call
22684 2004-10-04 Robert Dewar <dewar@gnat.com>
22686 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
22687 consider expressions buried within a procedure actual to be an actual.
22688 This caused some blowups with uses of packed slices within a procedure
22691 2004-10-04 Robert Dewar <dewar@gnat.com>
22693 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
22694 longer need to be initialized to zero.
22695 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
22696 initialized to zero.
22698 * checks.adb (Expr_Known_Valid): Packed arrays are now always
22699 considered valid, even if the representation is modular. That's correct
22700 now that we no longer initialize packed modular arrays to zero.
22702 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
22703 suffixes. These are now documented as the only cases in which the
22704 debugger ignores outer records.
22705 Previously, the spec allowed arbitrary suffixes for this purpose.
22706 Change name of LJM to JM for packed array pad records
22707 Create separate section on packed array handling, and add a whole new
22708 set of comments to this section describing the situation with packed
22709 modular types and justification requirements depending on endianness.
22711 2004-10-04 Robert Dewar <dewar@gnat.com>
22713 * a-except.adb: Add a comment for last change

22722 * sem_util.ads: Minor comment update
22724 2004-10-04 Ed Schonberg <schonberg@gnat.com>
22726 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
22727 Inline_Always when in Configurable_Run_Time mode.
22729 * sem_prag.adb (Process_Convention): If entity is an inherited
22730 subprogram, apply convention to parent subprogram if in same scope.
22731 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
22732 when in Configurable_Run_Time mode.
22734 2004-10-04 Ed Schonberg <schonberg@gnat.com>
22736 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
22737 class_wide type after component list has been inherited.
22739 2004-10-04 Ed Schonberg <schonberg@gnat.com>
22741 * sem_ch12.adb (Check_Generic_Actuals): New predicate
22742 Denotes_Previous_Actual, to handle properly the case of a private
22743 actual that is also the component type of a subsequent array actual.
22744 The visibility status of the first actual is not affected when the
22745 second is installed.
22746 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
22747 make fully recursive the treatment of formals of packages declared
22749 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
22750 the above on exit from an instantiation.
22751 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
22752 current instantiation which is now complete.
22753 (Analyze_Package_Instantiation): No instantiated body is needed if the
22754 main unit is generic. Efficient, and avoid anomalies when a instance
22755 appears in a package accessed through rtsfind.
22757 2004-10-04 Ed Schonberg <schonberg@gnat.com>
22759 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
22760 do not generate a declaration for a temporary if the call is part of a
22761 library-level instantiation.
22763 2004-10-04 Ed Schonberg <schonberg@gnat.com>
22765 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
22766 searching for a limited component to flag.
22768 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
22769 expansion of Input, to account for the fact that the implicit call
22770 generated by the attribute reference must freeze the user-defined
22771 stream subprogram. This is only relevant to 'Input, because it can
22772 appear in an object declaration, prior to the body of the subprogram.
22774 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
22775 expansion can proceed and further errors uncovered.
22776 (Minor clean up): Fix cases of using | instead of \ for continuation
22779 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

22787 * decl.c (gnat_to_gnu_entity, case object): Check and process a
22788 specified alignment before validating size.
22789 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
22790 stripped-down declaration for the type of the inner field when making
22793 * utils.c (finish_record_type): Do not compute the size in units
22794 incrementally. Instead compute it once for the rep clause case.
22795 Use gcc_assert and gcc_unreachable.
22797 2004-10-04 Vincent Celier <celier@gnat.com>
22799 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
22801 (Is_Valid_Path_Name): Take '/' as a directory separator.
22803 2004-10-04 Vincent Celier <celier@gnat.com>
22805 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
22806 (Extended_Project) only if Extended_Project is defined, to avoid
22808 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
22810 (Parse_Single_Project): Ditto.
22812 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
22813 Add_To_Project_Path for virtual projects.
22815 2004-10-04 Vincent Celier <celier@gnat.com>
22817 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
22818 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
22819 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
22820 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
22821 parameter Options_2.
22823 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
22824 Build_Dynamic_Library with an empty Options_2.
22826 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
22829 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
22830 directory separator, if any.
22831 (Gprmake): Do not allow mains on the command line for library projects.
22832 Do not attempt to link when the project is a library project.
22833 (Library_Opts): New table to store Library_Options.
22834 (Build_Library): If Library_Options is specified, pass these options
22835 when building a shared library.
22837 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
22839 * s-tposen.adb (Service_Entry): The object must be always unlocked at
22840 the end of this procedure now that the unlock operation was inserted
22843 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
22845 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
22846 corresponding to the Preallocated_Stacks flags in System.
22847 (Get_Target_Parameters): Including the processing for
22848 Preallocated_Stacks.
22850 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,

22860 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
22861 used to signal whether the compiler creates the required stacks and
22862 descriptors for the different tasks (when True) or it is done by the
22863 underlying operating system at run time (when False).
22864 It is initially set to False in all targets.
22866 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
22867 if it is supported by the target.
22868 (Make_Task_Create_Call): Pass the stack address if it has been
22869 previously created. Otherwise pass a Null_Address.
22871 * snames.adb: Add _stack.
22873 * snames.ads: Add Name_uStack. Required to allow the expander to
22874 statically allocated task stacks.
22876 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
22877 Stack_Address argument.
22878 Check that its value is equal to Null_Address because this target does
22879 not support the static stack allocation.
22881 2004-10-04 Thomas Quinot <quinot@act-europe.fr>

22888 * exp_dist.adb: Split declaration of asynchronous flag out of
22889 Add_RACW_Read_Attribute.
22890 Minor reformatting for better alignment with PolyORB version.
22891 Store the entity for the asynchronous flag of an RACW, rather than the
22892 expression, in the asynchronous flags table. This will allow this flag
22893 to be used in other subprograms beside Add_RACW_Read_Attribute.

22902 sockets constant MSG_NOSIGNAL (Linux-specific).
22903 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
22904 all Send operations.
22905 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
22906 from trigerring SIGPIPE.
22907 Rename components to avoid clash with Ada 2005 possible reserved

22922 Change "pragma inline" to "pragma Inline" in information and error
22924 Minor reformatting.
22926 * freeze.adb (Check_Address_Clause): Remove previous change, not the
22927 right way of doing things after all.
22928 (Freeze_Entity): For object, set Is_Public for imported entities
22929 unless there is an address clause present.
22931 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
22933 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
22934 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
22935 ensures proper handling of types with rep clauses, which might have
22936 their TYPE_SIZE set already.
22938 2004-09-21 Robert Dewar <dewar@gnat.com>
22940 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
22941 packed array types in both little- and big-endian cases. This change
22942 ensures that we no longer count on the unused bits being initialized
22943 for such types (and in particular ensures that equality testing will
22944 only read the relevant bits).
22945 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
22946 These changes mean that we no longer need to initialize small packed
22948 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
22949 optimization to an LJM field as to its parent field.
22951 * ada-tree.h, trans.c, utils.c, utils2.c:

22954 2004-09-20 Jan Hubicka <jh@suse.cz>
22956 * utils.c (gnat_finalize): Remove.

22958 do not lower the nested functions.
22960 2004-09-20 Robert Dewar <dewar@gnat.com>
22963 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public

22993 an existing directory.
22994 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
22995 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
22996 Convert the result to File_Size.
22998 * prj.ads: (Project_Error): New exception
23000 * prj-attr.adb: Except in procedure Initialize, Fail comes from
23001 Prj.Com, not from Osint.
23002 (Attrs, Package_Attributes): Tables moved to private part of spec
23003 (Add_Attribute, Add_Unknown_Package): Moved to new child package
23005 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
23006 Prj.Project_Error after call to Fail.
23007 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
23008 Fail. Check that package name is not already in use.
23010 * prj-attr.ads: Comment updates to indicate that all subprograms may be
23011 used by tools, not only by the project manager, and to indicate that
23012 exception Prj.Prj_Error may be raised in case of problem.
23013 (Add_Unknown_Package, Add_Attribute): Moved to new child package
23015 (Attrs, Package_Attributes): Table instantiations moved from the body to
23016 the private part to be accessible from Prj.Attr.PM body.
23018 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
23019 from new package Prj.Attr.PM.
23020 (Parse_Attribute_Declaration): Call Add_Attribute from new package
23023 * Makefile.in: Add prj-attr-pm.o to gnatmake object list

23071 pragmas recognized by GNAT.
23073 * gnat_rm.texi: Document pragma Detect_Blocking.
23075 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
23076 raise Program_Error if called from a protected operation.
23078 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
23079 the protected action nesting level.
23080 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
23081 protected action nesting level.
23082 (Unlock): When pragma Detect_Blocking is active decrease the protected
23083 action nesting level.
23085 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
23086 Protected_Action_Nesting.
23088 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
23089 Common_ATCB record. It contains the dynamic level of protected action
23090 nesting for each task. It is needed for checking whether potentially
23091 blocking operations are called from protected operations.
23092 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
23093 Detect_Blocking is active or not in the partition.
23095 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
23096 raise Program_Error if called from a protected operation.

23105 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
23106 raise Program_Error if called from a protected operation, and increase
23107 the protected action nesting level.
23108 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
23109 Program_Error if called from a protected operation, and increase the
23110 protected action nesting level.

23116 the protected action nesting level.
23117 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
23118 Program_Error if called from a protected operation, and increase the
23119 protected action nesting level.

23123 active, raise Program_Error if called from a protected operation.
23124 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
23125 protected action nesting level.
23127 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
23128 insertion of the statement raising Program_Error. The run time
23129 contains the required machinery for handling that.
23131 * sem_util.ads: Change comment associated to procedure
23132 Check_Potentially_Blocking_Operation.
23133 This procedure does not insert a call for raising the exception because
23134 that is currently done by the run time.
23136 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
23138 * init.c: Add the global variable __gl_detect_blocking that indicates
23139 whether pragma Detect_Blocking is active (1) or not (0). Needed for
23140 making the pragma available at run time.
23141 (__gnat_set_globals): Pass and update the detect_blocking parameter.
23143 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
23144 pragma Detect_Blocking is active.
23146 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
23148 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
23149 DB is found in the ali file. Any unit compiled with pragma
23150 Detect_Blocking active forces its effect in the whole partition.
23152 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
23153 Detect_Blocking is active and delay is called from a protected
23156 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
23157 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
23158 Detect_Blocking is active (0 otherwise).
23159 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
23160 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
23163 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
23165 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
23166 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
23169 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
23170 (Register_Receiving_Stub): Add Subp_Info formal parameter.
23171 Update API in placeholder implemetation of s-parint to reflect changes
23172 in distribution runtime library.
23174 * sem_ch3.adb (Expand_Derived_Record): Rename to
23175 Expand_Record_Extension.
23177 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
23178 primitive operations of potentially distributed object types that have
23179 non-controlling anonymous access formals.
23181 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
23183 New implementation of expansion for remote access-to-subprogram types,
23184 based on the RACW infrastructure.
23185 This version of sem_dist is compatible with PolyORB/DSA as well as
23188 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
23189 Asynchrronous that applies to a remote access-to-subprogram type, mark
23190 the underlying RACW type as asynchronous.
23192 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
23193 __gnat_using_gnu_linker to 1.
23195 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
23196 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
23197 GNAT.Perfect_Hash_Generators, and remove the empty

23202 * exp_ch3.adb (Expand_Derived_Record): Rename to
23203 Expand_Record_Extension.
23204 (Build_Record_Init_Proc.Build_Assignment): The default expression in
23205 a component declaration must remain attached at that point in the
23206 tree so New_Copy_Tree copies it if the enclosing record type is derived.
23207 It is therefore necessary to take a copy of the expression when building
23208 the corresponding assignment statement in the init proc.
23209 As a side effect, in the case of a derived record type, we now see the
23210 original expression, without any rewriting that could have occurred
23211 during expansion of the ancestor type's init proc, and we do not need
23212 to go back to Original_Node.
23214 * exp_ch3.ads (Expand_Derived_Record): Rename to
23215 Expand_Record_Extension.
23217 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
23218 Returns the RACW type used to implement a remote access-to-subprogram
23220 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
23221 New subprograms. Used to create a proxy tagged object for a remote
23222 subprogram. The proxy object is used as the designated object
23223 for RAS values on the same partition (unless All_Calls_Remote applies).
23224 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
23225 System.Partition_Interface.Get_Unique_Remote_Pointer.
23226 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
23227 Renamed from Add_RAS_*_Attribute.
23228 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
23230 New implementation of expansion for remote access-to-subprogram types,
23231 based on the RACW infrastructure.
23233 * exp_dist.ads (Copy_Specification): Update comment to note that this
23234 function can copy the specification from either a subprogram
23235 specification or an access-to-subprogram type definition.
23237 2004-09-09 Ed Schonberg <schonberg@gnat.com>
23239 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
23240 in an instance, between an explicit subprogram an one inherited from a
23241 type derived from an actual.
23243 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
23244 add a polling call if the subprogram is to be inlined by the back-end,
23245 to avoid repeated calls with multiple inlinings.
23247 * checks.adb (Apply_Alignment_Check): If the expression in the address
23248 clause is a call whose name is not a static entity (e.g. a dispatching
23249 call), treat as dynamic.
23251 2004-09-09 Robert Dewar <dewar@gnat.com>
23253 * g-trasym.ads: Minor reformatting
23255 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

23261 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
23264 2004-09-09 Pascal Obry <obry@gnat.com>
23266 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
23267 enable map file generation. Add the right option to generate the map
23268 file if Map_File is set to True.
23270 * gnatdll.adb (Gen_Map_File): New variable.
23271 (Syntax): Add info about new -m (Map_File) option.
23272 (Parse_Command_Line): Add support for -m option.
23273 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

23295 version of the language is used to compile the run time.
23297 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
23299 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
23300 of variable length temporaries for function return now that the
23301 back-end and gigi support it.

23495 for a global aliased object with a variable size and an unconstrained
23496 nominal subtype, pretend there is no initializer if the one we have is
23497 incomplete, and avoid referencing an inexistant component in there. The

23525 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
23526 discriminants that rename those of the parent, recover names of

23589 ignore overflows on low and high bounds of an index to also account for
23590 differences in signedness between sizetype and gnu_index_subtype.

27508 complete assignment subtree which is now unnecessary, as the expansion
27509 of inlined call has been improved to preserve a consistent assignment
27510 tree. Note_Possible_Modification must be called only
27511 after checks have been applied, or else unnecessary checks will

27735 (Set_Actual_Subtypes): Generate null-excluding subtype if the
27736 null-excluding part was present; it is not required to be done here in
27737 case of anonymous access types.
27738 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
27741 * sem_res.adb (Resolve_Actuals): Carry out some static check
27742 (Resolve_Null): Allow null in anonymous access
27744 * sinfo.adb: New subprogram Null_Exclusion_Present
27745 All_Present and Constant_Present available on access_definition nodes
27747 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
27748 object_declaration, derived_type_definition, component_definition,
27749 discriminant_specification, access_to_object_definition,
27750 access_function_definition, allocator, access_procedure_definition,
27751 access_definition, parameter_specification, All_Present and
27752 Constant_Present flags available on access_definition nodes.

27768 * sem_ch12.adb: Add comment for previous change
27770 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
27772 * osint.adb (Executable_Prefix): Set Exec_Name to the current
27773 executable name when not initialized. Otherwise, use its current value.
27775 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
27776 initialize it to another executable name than the current one. This
27777 allows to configure paths for an executable name (gnatmake) different
27778 from the current one (gnatdist).
27780 2004-03-29 Ed Schonberg <schonberg@gnat.com>
27782 * exp_ch6.adb (Expand_Call): A call to a function declared in the
27783 current unit cannot be inlined if it appears in the body of a withed
27784 unit, to avoid order of elaboration problems in gigi.
27786 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
27787 information for protected (wrapper) operation as well, to simplify gdb
27790 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
27791 protected body, indicate that the entity for the generated spec comes
27792 from source, to ensure that references are properly generated for it.
27793 (Build_Body_To_Inline): Do not inline a function that returns a
27796 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
27797 apply convention to homonyms that are declared explicitly.
27799 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
27800 that renames an equality operator and the operands are overloaded,
27801 resolve them with the declared formal types, before rewriting as an
27804 2004-03-29 GNAT Script <nobody@gnat.com>
27806 * Make-lang.in: Makefile automatically updated
27808 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
27810 * memtrack.adb: Log realloc calls, which are treated as free followed
27813 2004-03-25 Vincent Celier <celier@gnat.com>
27815 * prj-makr.adb (Process_Directories): Detect when a file contains
27816 several units. Do not include such files in the config pragmas or

27825 resolve links when computing the display names.
27827 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
27829 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
27830 attribute reference does not denote a subtype, it can be any
27831 expression that has a classwide type, potentially after an implicit
27832 dereference. In particular, the prefix can be a view conversion for
27833 a classwide type (for which Is_Object_Reference holds), but it can
27834 also be a value conversion for an access-to-classwide type. In the
27835 latter case, there is an implicit dereference, and the original node
27836 for the prefix does not verify Is_Object_Reference.
27838 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
27839 conversion of a discriminant-dependent component of a mutable object
27842 2004-03-25 Ed Schonberg <schonberg@gnat.com>
27844 * freeze.adb (Freeze_Entity): When an inherited subprogram is
27845 inherited, has convention C, and has unconstrained array parameters,
27846 place the corresponding warning on the derived type declaration rather
27847 than the original subprogram.
27849 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
27850 indication on renaming declaration, if formal has a box and actual
27853 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
27854 determine whether to generate an implicit or explicit reference to
27855 the renamed entity.
27857 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
27858 subprogram renaming comes from a defaulted formal subprogram in an
27861 2004-03-25 Gary Dismukes <dismukes@gnat.com>
27863 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
27864 value expressions to ensure that calls within a component definition
27865 will be checked (since those are evaluated during the record type's
27868 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
27870 * s-tpobop.adb: Code clean up:
27871 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

27887 * ali.ads: Fix Comment about Dynamic_Elab.
27889 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
27890 Has_RACW, Is_Generic, etc.)
27891 (Output_Object, Gnatls): Take into account ALI files not attached to
27894 2004-03-22 Vincent Celier <celier@gnat.com>
27896 * gprep.adb: Change all String_Access to Name_Id
27897 (Is_ASCII_Letter): new function
27898 (Double_File_Name_Buffer): New procedure
27899 (Preprocess_Infile_Name): New procedure

27901 (Gnatprep): Check if output and input are existing directories.
27902 Call Process_Files to do the real job.

27909 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
27911 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
27912 case when the source contains only comments.
27914 2004-03-22 Ed Schonberg <schonberg@gnat.com>
27916 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
27917 declaration for a child subprogram body that acts as a spec, indicate
27918 that the entity in the declaration needs debugging information.
27920 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
27921 full view if the subtype is created for a constrained record component;
27922 gigi has enough information to construct the record, and there is no
27923 place in the tree for the declaration.
27925 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
27926 serial number for the dummy body that is built for analysis, to avoid
27927 inconsistencies in the generation of internal names when compiling
27930 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
27932 * sem_util.adb (Is_Object_Reference): A view conversion denotes an

27957 * gnat_ug.texi: Add info directory category and entry.
27958 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
27959 gnat_ug_wnt.texi: Regenerate.
27961 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
27963 * ada-tree.h: Update copyright notice.
27964 Minor reformatting.
27966 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
27968 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
27969 as regular exception objects and not as mere integers representing the
27970 condition code. The latter approach required some dynamics to mask off
27971 severity bits, which did not fit well into the GCC table based model.
27972 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
27973 exception data objects. We don't it and it would conflict with the other
27974 external symbol we have to generate for such exceptions.
27976 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
27977 the special code for VMS exceptions, since these are now represented
27978 as regular exceptions objects.
27980 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27982 * decl.c (debug_no_type_hash): Remove.

27984 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
27986 2004-03-19 Laurent Guerby <laurent@guerby.net>
27988 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
27989 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
27991 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27993 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
27994 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
27995 (TYPE_RM_SIZE_INT): Directly use type.values.
27996 (TREE_LOOP_ID): Clean up check.
27997 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
27998 TYPE_VALUES, not TYPE_FIELDS.
27999 * trans.c (convert_with_check): Delay access of bounds of basetype
28000 until sure is numeric.

28008 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
28009 Specific.Set instead of direct call to e.g pthread_setspecific.
28011 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
28013 * adaint.c: Update comments.
28015 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
28016 GNATLIB_SHARED for FreeBSD.
28018 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
28020 * init.c [VxWorks]: Do not fix the stack size for the environment task.
28021 When needed (stack checking) the stack size is retrieved
28022 from the VxWorks kernel.
28024 * Makefile.in: Flag -nostdinc is required when building the run time
28025 for avoiding looking for files in the base compiler.
28026 Add the VxWorks specific version of the package body for
28027 System.Stack_checking.Operations (5zstchop.adb).
28029 * Make-lang.in: Add the object file for
28030 System.Stack_Checking.Operations.
28032 * Makefile.rtl: Add object file for the package
28033 System.Stack_Checking.Operations.
28035 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
28037 * s-stache.ads, s-stache.adb: Move the operations related to stack
28038 checking from this package to package System.Stack_Checking.Operations.
28039 This way, stack checking operations are only linked in the final
28040 executable when using the -fstack-check flag.
28042 2004-03-18 Doug Rupp <rupp@gnat.com>
28044 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
28047 * 5qsystem.ads, 5xcrtl.ads: New files.

28053 * prj-env.adb (Source_Paths, Object_Paths): New tables.
28054 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
28055 the procedures Add_To_Path_File.
28056 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
28057 making sure that each directory is present only once and, for object
28058 dirs, when a directory already present is added, the duplicate is
28059 removed and the directory is always put as the last in the table.
28060 Write the path files at the end of these accumulations.
28062 * prj-nmsc.adb (Record_Source): Add source file name in hash table
28063 Files_Htable for all sources.
28065 * prj-proc.adb (Process): Remove restrictions between not directly
28066 related extending projects.
28068 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

28074 parameter Trusted_Mode.
28076 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
28078 * scn.adb (Determine_License): Take into account a degenerated case
28079 when the source contains only comments.
28081 2004-03-18 Ed Schonberg <schonberg@gnat.com>
28083 * sem_warn.adb (Check_References): For a warning on a selected
28084 component that does not come from source, locate an uninitialized
28085 component of the record type to produce a more precise error message.
28087 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
28089 * 3zsoccon.ads: Fix multicast options.
28091 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
28094 2004-03-15 Robert Dewar <dewar@gnat.com>
28096 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
28097 pragma used for a private type.
28099 * lib-xref.adb (Generate_Reference): Do not generate warning if
28100 reference is in a different unit from the pragma Unreferenced.
28102 * 5vtpopde.adb: Minor reformatting
28103 Fix casing of To_Task_ID
28105 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
28106 flag if we have an unchecked conversion to an access type in the same
28109 2004-03-15 Geert Bosch <bosch@gnat.com>
28111 * a-ngcoty.adb (Modulus): In alternate formula for large real or
28112 imaginary parts, use Double precision throughout.
28114 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
28115 we want to be able to compile run-time with -gnata for testing, but
28116 this may also be instantiated in user code that is compiled with -gnata.
28118 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
28120 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
28121 codes. Having a separate type for this is useful to enforce consistency
28122 throughout the various run-time units.
28123 (Exception_Data): Use Exception_Code for Import_Code.
28125 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
28126 Natural and Integer in various places.

28128 with the severity bits masked off.
28129 (Register_VMS_Exception): Handle the additional exception data pointer

28135 occurrence matches some handler choice specification. Extracted out of
28136 get_action_description_for, and expanded to take care of the VMS
28138 (get_action_description_for): Use is_handled_by instead of an explicit
28139 complex condition to decide if the current choice at hand catches the
28140 propagated occurrence.
28142 * raise.h (Exception_Code): New type for C.
28144 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
28145 System.Standard_Library.Exception_Code, to allow references from the
28146 pragma import/export expander.
28148 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
28149 New accessors to allow easy access to GNAT exception data
28151 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
28152 redundant Handled_By_Others component, helper for the personality
28153 routine which will now be able to call the appropriate exception data
28156 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
28157 component of Standard_Exception_Type to be the closest possible to
28158 Exception_Code in System.Standard_Library, that we cannot get at this
28159 point. Expand a ??? comment to notify that this type node should
28160 probably be rewritten later on.
28162 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
28163 registration call to include a pointer to the exception object in the
28166 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
28167 instead of int and explicit bitmasks.
28169 2004-03-15 Vincent Celier <celier@gnat.com>
28171 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
28172 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
28174 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
28175 longer needed now that it is in the spec of
28176 System.Tasking.Task_Attributes.
28178 * adaint.h, adaint.c: (__gnat_create_output_file): New function
28180 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
28182 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
28184 * make.adb (Gnatmake): Do not check the executable suffix; it is being
28185 taken care of in Scan_Make_Arg.
28186 (Scan_Make_Arg): Add the executable suffix only if the argument
28187 following -o, in canonical case, does not end with the executable
28188 suffix. When in verbose mode and executable file name does not end
28189 with executable suffix, output the executable name, in canonical case.
28191 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
28192 to avoid warnings when instantiating Ada.Task_Attributes.
28195 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
28196 in the correct order.
28198 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
28199 redirect standard output and error to a file for the invocation of the
28200 compiler, then read the file.
28202 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
28203 directory, instead of the Value.
28204 (Find_Source_Dirs): Remove useless code & comments.
28206 2004-03-15 Ed Schonberg <schonberg@gnat.com>
28208 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
28209 tagged type is inherited, and the parent operation is not frozen yet,
28210 force generation of a freeze node for the inherited operation, so the
28211 corresponding dispatch entry is properly initialized.
28212 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
28213 when looking for user-defined equality operation.
28215 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
28216 boolean when locating primitive equality of tagged component.
28218 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
28219 bit-aligned field and the right-hand side a string literal, introduce
28220 a temporary before expanding assignment into a loop.
28222 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
28223 priority in full, to ensure that any expanded subepxressions of it are
28224 elaborated in the scope of the init_proc.
28226 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
28227 after object declaration, skipping over code that may have been
28228 generated for validity checks.
28230 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
28231 discriminants, ignore the known discriminants of its full view, if
28232 any, to check legality.
28234 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
28235 component if type has unknown discriminants.
28236 (Analyze_Private_Extension_Declaration): Discriminant constraint is
28237 null if type has unknown discriminants.
28239 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference

29162 checks for bitfield creation are triggered.
29163 (finish_record_type): During last pass over the fields, clear
29164 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

29506 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity

29623 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
29624 N_String_Literal node always references an E_String_Literal_Subtype
29625 entity. This may not be true in the future.
29626 (Possible_Bit_Aligned_Component): Move processing of
29627 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
29629 * exp_ch6.adb (Expand_Thread_Body): Pick up

29634 (Type_May_Have_Bit_Aligned_Components): New function.

29674 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
29675 ineffective elaborate all pragmas on non-visible packages (this
29676 happened when a renamed subprogram was called). Now the elaborate all
29677 always goes on the package containing the renaming rather than the one
29678 containing the renamed subprogram.
29680 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
29681 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

29706 * make.adb (Gnatmake): Special process for files to compile/check when
29707 -B is specified. Fail when there are only foreign mains in attribute

29742 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
29743 all attributes, including read-only attribute.

29782 checked when limited aggregates are implemented.

29785 pure, emit warning.

29895 * 5zinit.adb: Clean up.
29897 * 5zintman.adb (Notify_Exception): replaced case statement with a call
29898 to __gnat_map_signal, imported from init.c to support
29899 signal -> exception mappings that depend on the vxWorks version.
29902 Created and exported __gnat_map_signal to support signal -> exception
29903 mapping that is dependent on the VxWorks version.

29932 Minor reformatting throughout
29934 2003-12-11 Ed Schonberg <schonberg@gnat.com>
29936 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
29937 bounds of a loop, create a separate block in order to generate proper
29938 cleanup actions to prevent memory leaks.
29940 * sem_res.adb (Resolve_Call): After a call to
29941 Establish_Transient_Scope, the call may be rewritten and relocated, in

29960 2003-12-08 Robert Dewar <dewar@gnat.com>
29962 * 7sintman.adb: Minor reformatting
29964 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
29965 standard linker options to get standard libraries linked. We now plan
29966 to provide dummy versions of these libraries to match the appropriate
29967 configurable run-time (e.g. if a library is not needed at all, provide
29968 a dummy empty library).
29970 * targparm.ads: Configurable_Run_Time mode no longer affects linker
29971 options (-L parameters and standard libraries). What we plan to do is
29972 to provide dummy libraries where the libraries are not required.
29974 * gnatbind.adb: Minor comment improvement

29986 of aggregate with default initialized components.
29987 (Has_Default_Init_Comps): Improve implementation to recursively check
29988 all the present expressions.
29990 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
29991 to indicate that the initialization call corresponds to a
29992 default-initialized component of an aggregate.
29993 In case of default initialized aggregate with tasks this parameter is
29994 used to generate a null string (this is just a workaround that must be
29995 improved later). In case of discriminants, this parameter is used to
29996 generate a selected component node that gives access to the discriminant
29999 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
30000 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
30001 allocated aggregates with default-initialized components.

30046 Process nodes N_Comment.
30048 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
30049 without comments and there are some comments, set the flag
30050 Unkept_Comments to True.

30092 Correct typo in comment
30093 (Resolve_Aggregate): In case of array aggregates set the estimated
30094 type of the aggregate before calling resolve. This is needed to know
30095 the name of the corresponding IP in case of limited array aggregates.
30096 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
30097 in case of default initialized array components.

30119 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
30120 they are automatically generated by Make-lang.in and cause nothing but
30121 maintenance troubles.
30123 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
30125 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

30139 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
30140 to ensure that the kernel fills in the interrupted context structure
30141 before calling a signal handler, which is necessary to be able to
30142 unwind past it. Update the copyright notice.
30144 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
30146 * a-elchha.ads: New file.

30233 2003-12-03 Ed Schonberg <schonberg@gnat.com>
30236 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
30237 is legal in an instance, because legality is cheched in the template.

30258 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
30259 so that the debugger can reliably access the value of the parameter,

33788 2002-01-30 Richard Henderson <rth@redhat.com>
33790 * trans.c (tree_transform) [N_Loop_Statement]: Use
33791 expand_exit_loop_top_cond.

33809 (general) Add @./@: where approriate, and two spaces after the
33810 full stop at the end of a sentence. Use @samp markup when
33811 referring concrete lexical entities (keywords, attribute names
33812 etc.), and @syntax for ARM grammar elements. Use @r for English

33828 function approach did not work well because of a side effect (the
33829 function call could reallocate the table which was being indexed
33830 using its result). Fixes ada/4851.

33868 * raise.c (__gnat_eh_personality): Exception handling personality
33869 routine for Ada. Still in rough state, inspired from the C++ version

33891 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
33892 need to force universal inlining for these cases.
33894 2001-12-19 Arnaud Charlet <charlet@gnat.com>
33896 * s-taprob.adb: Minor clean ups so that this unit can be used in

34197 2001-12-17 Laurent Pautet <pautet@gnat.com>
34200 Fix comment of Shutdown_Socket and Close_Socket. These functions
34201 should not fail silently because if they are called twice, this
34202 probably means that there is a race condition in the user program.
34203 Anyway, this behaviour is consistent with the rest of this unit.
34204 When an error occurs, an exception is raised with the error message
34205 as exception message.

34358 reference nodes, since this field is used in such nodes.

35544 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
35545 instead of simple checksum.
35546 (CRC_Match): new function.
35547 (CRC_Error): new constant.
35549 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
35550 a CRC now and not a simple checksum. A CRC uses lower-case hex
35551 letters, fixes ambiguity in parsing.
35553 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
35554 is what this variable will store.
35556 * bcheck.adb: Change reference to chechsum in comments by CRC.
35557 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
35558 rename All_Checksum_Match to All_CRC_Match. Change due to API
35559 renaming since now GNAT does not use a simple checksum but a
35560 CRC using GNAT.CRC32.
35562 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
35563 now and not anymore a simple checksum.

35600 Update comments for the CRC.
35602 * types.adb (Hex): Use lowercase for the letter part.
35604 * types.ads (Get_Hex_String): Returns the hexadecimal representation
35605 for a word. This is currently used only for CRC. In previous version,
35606 the checksum was using a representation with all letter being
35607 upper-case. With the new implementation (using CRC) we do not remove
35608 the 32th bit of the CRC, so we can have an upper-case starting letter
35609 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
35610 It is ambigous since the CRC was optional and could be followed by
35611 options like EB, EE. So now this routines uses lower-case letter for
35612 the hexadecimal representation. Strange enough only lower case letters
35613 where checked in Scan_ALI (even if this was not a possible case).
35615 * gnatvsn.ads (Library_Version): changed to 3.15a.
35617 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
35620 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
35623 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
35624 Add 2001 to copyright notice
35625 (Accumulate_Checksum): Modify to use System.CRC32.
35627 * ali-util.ads: Redo changes of previous revision to continue to use
35628 the word Checksum. Add 2001 to copyright notice.
35630 * ali.adb: Undo some of previous changes, not needed.
35631 Keep the change for lower case letters in the checksum.
35633 * ali.ads: Undo previous change not needed.
35635 * bcheck.adb: Undo most of previous change, not needed.
35636 But do use Checksums_Match for checksum comparison.
