2023 WITH clause on a private sibling.
2024 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
2025 child unit is a renaming, create an implicit with_clause on that

2091 formal of a generic subprogram. find candidate interpretations by
2092 scanning the list of generic formal declarations.:
2093 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
2094 type from a limited_with_clause, and the full view is available, use it
2095 for subsequent semantic checks.

2125 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
2126 requeue statement is dispatching. Do not emit an error when the name is

2129 and those of the target interface primitive.
2130 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
2131 Timed_Entry_Call): Analyze the triggering statement as the first step of
2132 the processing. If this is a dispatching select, postpone the analysis
2133 of all select statements until the Expander transforms the select. This
2134 approach avoids generating duplicate identifiers after the Expander has
2135 replicated some of the select statements. In case the Expander is
2136 disabled, perform regular analysis.
2137 (Check_Triggering_Statement): New routine.
2138 (Analyze_Requeue): Exclude any interpretations that are not entries when
2139 checking overloaded names in a requeue. Also test type conformance for
2140 matching interpretations rather than requiring subtype conformance at

2735 multiple inherited interfaces info. This information cannot be stored
2736 in Xref_Entity_Record, which only supports a single instance of Tref_*,

2753 additional management on these nodes in Expand_Interface_Actuals.
2755 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
2756 that handles use of 'Access and 'Unchecked_Access applied to

2802 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
2803 used by VxWorks targets to have access to task-specific data and be
2804 able to extract the stack boundaries for stack checking.

2849 association for an access component, add an association with null as
2850 the expression. Remove testing for array subtypes and the setting in
2851 that case of Ctyp to the array component type, which prevented proper
2852 inclusion of an association for null-initialized arrays. Collapse
2853 condition that tests for array subtypes into just a test of
2854 Is_Partially_Initialized_Type (which already covers arrays anyway).

2871 * sem_ch4.adb: Minor code and comment reformatting.
2872 (Analyze_Allocator): When the designated type of an unconstrained

3037 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
3039 * a-calend-vms.adb, a-calend.adb:
3040 Add a section on leap seconds control along with two entities used to
3041 enable and disable leap seconds support. The array Leap_Second_Times is
3042 now constant and contains hard time values pre-generated. Remove
3043 all elaboration code used to populate the table of leap seconds.
3046 Add entity Leap_Seconds_Support to the list of global run-time variables
3047 along with a comment on its usage and values.
3048 (Gen_Adainit_Ada): Add code to generate the declaration and import of
3049 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
3050 or one (enabled) depending on the presence of binder switch "-y".
3051 (Gen_Adainit_C): Add code to generate the declaration of external int
3052 __gl_leap_seconds_support. Set is value to zero (disabled) or one
3053 (enabled) depending on the presence of binder switch "-y".
3055 * init.c: Add __gl_leap_seconds_support to the list of global values
3056 computed by the binder.
3058 2007-09-26 Jerome Guitton <guitton@adacore.com>

3062 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
3063 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
3065 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
3067 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
3068 function which can be called by the debugger to interrupt the tasks of
3069 an Ada application asynchronously, as needed on VxWorks.
3070 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
3072 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
3073 renamed from Stop_All_Tasks. Update comments.
3074 (Stop_All_tasks): New function declaration.
3076 2007-09-26 Olivier Hainque <hainque@adacore.com>
3078 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
3079 #include <utime.h> and #define GCC_RESOURCE_H before
3080 #include <sys/wait.h>.
3081 Add more protections in __gnat_translate_vms.
3083 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
3084 #include <sys/wait.h>.
3086 2007-09-26 Thomas Quinot <quinot@adacore.com>
3087 Sergey Rybin <rybin@adacore.com>
3089 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
3091 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
3094 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
3096 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
3099 * sem_dist.ads: Minor comment fix
3101 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
3103 2007-09-26 Javier Miranda <miranda@adacore.com>
3104 Eric Botcazou <ebotcazou@adacore.com>
3107 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
3108 indirection added to the HT_Link component of the TSD. This is required
3109 to statically allocate the TSD.
3112 Minor reordering of the declarations in the private part. Required to
3113 add a level of indirection to the contents of the TSD component HT_Link.
3114 This is required to statically allocate the TSD.
3116 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
3117 Is_Statically_Allocated set from constant objects.
3118 Do not make exported constants created by the compiler volatile.
3119 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
3122 * trans.c (Identifier_to_gnu): For constants, unshare initializers
3123 before returning them.
3125 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
3126 public part of the package.
3127 (Make_DT): Move HT_Link component out of the TSD record. For this
3128 purpose Make_DT now declares a separate object that stores the
3129 HT_Link value, and initializes the TSD component with the address
3130 of this new object. The addition of this level of indirection is
3131 required to statically allocate the TSD because the TSD cannot
3132 have variable components.
3133 (Expand_Interface_Conversion): Improve the expanded code.
3134 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
3136 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
3137 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
3138 if we are building static dispatch tables then we must not generate
3139 extra code to register the primitive because the dispatch table will
3140 be built at the end of the library package; otherwise we notify that
3141 we cannot build the static dispatch table.
3143 2007-09-26 Robert Dewar <dewar@adacore.com>
3145 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
3148 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
3149 (Analyze_Record_Representation_Clause): Suppress junk warning for
3150 missing component clause.

3152 tests for controlled type overlay to composites with controlled
3154 (Analyze_Record_Representation_Clause): Add reference for component name
3156 2007-09-26 Javier Miranda <miranda@adacore.com>
3157 Gary Dismukes <dismukes@adacore.com>

3160 for thunks associated with interface types.
3162 * einfo.ads: Improve documentatation of Is_Internal
3163 (Is_Thunk): New attribute applicable to subprograms. True for thunks
3164 associated with interface types.
3165 Extensive comment fixes regarding flags that appear in all entities. The
3166 documentation is now consistent for all such flags (there were a number
3167 of errors in the documentation in this regard).
3169 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
3171 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
3172 of these procedures are passed a function call that already has
3173 build-in-place actuals (testing new flag
3174 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
3175 the case where processing continues.
3176 (Expand_Call): If the call is generated from a thunk body then we
3177 propagate the extra actuals associated with the accessibility
3178 level of the access type actuals.
3180 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
3181 of each extra formal of a protected operation to reference the
3182 corresponding extra formal of the subprogram denoted by the
3183 operation's Protected_Body_Subprogram.
3185 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
3186 N_Function_Call nodes.
3188 2007-09-26 Robert Dewar <dewar@adacore.com>
3190 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
3192 * debug.adb: Add d.s flag.
3194 2007-09-26 Gary Dismukes <dismukes@adacore.com>
3196 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
3197 debug variable so that it won't be initialized when pragma
3198 Initialize_Scalars is in effect.
3200 2007-09-26 Gary Dismukes <dismukes@adacore.com>
3202 * freeze.adb (Freeze_Entity): Remove check for preelaborable
3203 initialization of a full view. This is moved to
3204 Analyze_Package_Specification.
3206 * sem_ch7.adb (Analyze_Package_Specification): Add check for
3207 preelaborable initialization of a full view in entity loop.
3208 (Uninstall_Declarations): If entity is a use-visible compilation unit,
3209 its child units are use-visible only if they are visible child units.
3211 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
3212 whether an expression can be used within a type declaration that
3213 requires preelaborable init.
3214 (Check_Components): Replace inline code that does partial checking for
3215 preelaborable default expressions with call to
3216 Is_Preelaborable_Expression.
3217 (Has_Preelaborable_Initialization): In the case of a generic actual
3218 subtype, (that is, Is_Generic_Actual is True), return the result of
3219 applying Has_Preelaborable_Initialization to the generic actual's base
3222 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
3224 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
3225 call to Jan_1_Day _Of_Week to optimize its performance.
3226 (Is_Leap): Move the routine to the scope of Week_In_Year.
3227 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
3228 weekday on which January 1 falls of Year - 1 and Year + 1. This function
3229 avoids calling Time_Of and Split, thus making it more efficent.
3230 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
3232 * g-calend.ads (Week_In_Year): Change comment to reflect new
3235 2007-09-26 Emmanuel Briot <briot@adacore.com>
3237 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
3238 Command_Line): New types
3239 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
3240 support for defining how switches can be grouped on a command line (as
3241 is the case for -gnatw... for GNAT), and how simple switches can be
3242 used as aliases for more complex switches (-gnatwa is same as
3244 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
3245 (Start, Current_*): New subprograms
3246 Added support for parsing an array of strings in addition to the real
3248 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
3249 be moved from the body to the private part of the spec.
3250 (*): All subprograms now have an extra parameter with default value to
3251 specify which parser should be used. For backward compatibility, it
3252 defaults to parsing the command line of the application. They were also
3253 modified to properly handle cases where each of the argument does not
3254 start at index 1 (which is always true for Ada.Command_Line, but not
3255 when processing any Argument_List).
3256 (Free): New subprogram
3257 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
3258 Argument): New subprograms
3259 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
3260 special characters like ':', '=',... are now handled in a single place,
3261 which makes the code more extensible eventually.
3262 (Getopt, Full_Switch): When the switch was returned as part of the
3263 special character '*', make sure it is prepended by the switch character
3264 ('-' in general), so that the application knows whether "foo" or "-foo"
3265 was specified on the command line.
3267 2007-09-26 Florian Villoing <villoing@adacore.com>
3269 * g-dirope.adb (Remove_Dir): In case we are removing directories
3270 recursively, make sure that if an exception is raised during the
3271 processing, the current working directory is reset to its initial
3272 value before propagating the exception.
3274 2007-09-26 Vincent Celier <celier@adacore.com>
3276 * gnatbind.adb: If there are several ALI files specified and there is
3277 a main program to bind, the first ALI is expected to contain the main
3278 subprogram and the names of the binder generated files will be derived
3279 from the first ALI file name.
3280 (Gnatbind): Fix insertion character in invocation of Error_Msg
3282 2007-09-26 Vincent Celier <celier@adacore.com>
3284 * gnatcmd.adb (Check_Files): Do not include sources that have been
3285 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
3287 2007-09-26 Ed Schonberg <schonberg@adacore.com>
3289 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
3290 information about each of its index types, following the type
3291 reference for its component type.
3293 2007-09-26 Vincent Celier <celier@adacore.com>
3295 * make.adb: (Kill): New procedure (__gnat_kill imported)

3297 were previously local to procedure Compile_Sources.
3298 (Sigint_Intercepted): Send signal SIGINT to all outstanding
3299 compilation processes.

3302 sources, so that the correct paths will be found.
3304 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
3306 2007-09-26 Vincent Celier <celier@adacore.com>
3308 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
3310 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
3311 Replace components Compiler_Min_Options and Binder_Min_Options with
3312 Compiler_Required_Switches and Binder_Required_Switches in record
3314 Remove components Default_Language and Config in Project_Tree_Data,
3317 * prj-attr.adb: New attributes Required_Switches (<language>) in
3318 packages Compiler and Binder.
3320 * prj-nmsc.adb: Major rewrite of the processing of configuration
3321 attributes for gprbuild. No impact on GNAT tools.
3323 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
3324 process configuration attributes: this is done in Prj.Nmsc.Check.
3325 (Recursive_Process): Make a full copy of packages inherited from project
3326 being extended, instead of a shallow copy.
3327 (Process_Project_Tree_Phase_1): New procedure
3328 (Process_Project_Tree_Phase_1): New procedure
3329 (Process): Implementation now uses the two new procedures
3331 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
3332 from the project config, not the tree config that no longer exists.
3334 2007-09-26 Vincent Celier <celier@adacore.com>

3355 2007-09-26 Ed Schonberg <schonberg@adacore.com>
3357 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
3358 ancestor of the derived type, the operations are inherited from the
3359 primary dispatch table of the parent.
3360 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
3361 when the context is an explicit type conversion.
3363 2007-09-26 Ed Schonberg <schonberg@adacore.com>
3365 * sem_ch4.adb (Analyze_Qualified_Expression): Apply name resolution

3408 no sources, but is an extending project.
3410 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
3412 * trans.c: Fix misplaced #define.

3538 * einfo.ads, einfo.adb (Dispatch_Table_Wrapper): New attribute. Present
3539 in library level record type entities if we are generating statically
3540 allocated dispatch tables.
3542 * exp_disp.adb (Make_Tags/Make_DT): Replace previous code
3543 importing/exporting the _tag declaration by new code
3544 importing/exporting the dispatch table wrapper. This change allows us
3545 to statically allocate of the TSD.

3552 allocate the dispatch tables.
3553 (Check_Allocator): Make function iterative instead of recursive.
3554 Also return inner allocator node, when present, so that we do not have
3555 to look for that node again in the caller.

3658 Thomas Quinot <quinot@adacore.com>
3660 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
3661 create an abstract subprogram in the case of 'Input. For 'Output we now
3662 create a real spec/body when the type is abstract, since it can
3663 potentially be called.
3664 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
3665 body for 'Output when the type is abstract (only the creation of the
3666 body for 'Input is excluded when the type is abstract).
3667 (Stream_Operation_OK): Add an additional condition in the return
3668 statement, so that False will be returned for TTS_Stream_Input if the
3669 associated tagged type is an abstract extension. Add comments for
3671 (Expand_N_Object_Declaration): For the case of a shared passive
3672 variable, insert init proc call only after the shared variable
3673 procedures have been processed, because the IP call needs to undergo
3674 shared passive variable reference expansion, which requires these
3675 procedures to be available (and elaborated).

3684 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
3685 given a box association, the type of the component is discriminated,
3686 and the value of the discriminant is the discriminant of the enclosing
3687 type, retrieve its value from the aggregate itself, where it must have
3690 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
3691 to remove other spurious ambiguities on arithmetic operations involving
3692 literals and addresses, on systems where Address is a visible integer
3693 type, when the operator is called in functional notation.
3694 (Try_Primitive_Operation): Within an instance, a call in prefixed form
3695 is legal when the types match, even if the operation is currently
3698 2007-09-10 Ed Schonberg <schonberg@adacore.com>
3700 * sem_ch12.adb (Build_Local_Package): A formal package with no
3701 associations is legal if all formals have defaults. It is not
3702 equivalent to a formal declared with a box.

3734 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
3735 which a constant renaming is treated as a normal object declaration.
3736 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
3737 the N_Indexed_Component case.
3738 <N_Indexed_Component>: Fall through to above case.

3820 (Write_Entity_Flags): Write the status of flag Is_Raised.
3821 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
3822 spurious ambiguities when integer literals appear in the context of an
3823 address type that is a visible integer type.
3825 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
3826 exceptions never being raised.
3827 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

3841 2007-08-31 Gary Dismukes <dismukes@adacore.com>
3843 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
3844 library-level package renaming, pass the declaration associated with
3845 the renaming's special debug variable to Qualify_Entity_Names to ensure
3846 that its encoded name is properly qualified.
3848 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
3849 occurring in the list of entities to qualify, and do not attempt to

3859 access type points to an unconstrained array.
3861 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
3863 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
3866 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

3877 avoid very deep recursion in the front end, which was causing stack
3880 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
3881 string, and the right operand is a string literal (the case of "" &

3885 * stringt.adb (Store_String_Chars): Optimize by growing the
3886 String_Chars table all at once, rather than appending characters one by
3888 (Write_String_Table_Entry): If the string to be printed is very long,
3889 just print the first few characters, followed by the length. Otherwise,
3890 doing "pn(n)" in the debugger can take an extremely long time.
3892 * sem_prag.adb (Process_Interface_Name): Replace loop doing
3893 Store_String_Char with Store_String_Chars.

3910 2007-08-31 Ed Schonberg <schonberg@adacore.com>
3912 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
3913 flag, for effiency. It is called when analyzing arithmetic operators
3914 and also for actuals in calls that are universal_integers. The flag is
3915 set for the predefined type address, and for any type or subtype
3918 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
3919 Universal_Integer, when the formal is a descendent of address and the
3920 call appears in user code.
3921 (Analyze_Selected_Component): if the prefix is a private extension, the
3922 tag component is visible.
3924 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an

3967 * gnat_ugn.texi: Add description for the new gnatpp
3968 '--separate-stmt-name' and '--use-on-new-line' options.

3981 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
3983 * misc.c (gnat_type_max_size): Constify.
3985 2007-08-16 Gary Dismukes <dismukes@adacore.com>
3987 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
3988 associated with Standard_Debug_Renaming_Type, to be used as the type of
3989 the special variables whose names provide debugger encodings for
3990 renaming declarations.
3992 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
3993 (Set_Debug_Renaming_Link): Change to set Node25.
3994 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
3995 (Write_Field25_Name): Add case for E_Variable to output
3996 "Debug_Renaming_Link".
3997 (Write_Field23_Name): Correct the output string for "Limited_View".
3999 * exp_dbug.adb: Add with and use of Tbuild.
4000 (Debug_Renaming_Declaration): Replace creation of an enumeration type
4001 and literal with creation of a variable of type
4002 Standard_Debug_Renaming_Type whose name encodes both the renamed object
4003 and the entity of the renaming declaration.
4004 (Qualify_Entity_Name): Add the delayed qualification of the entity name
4005 part of the name of a variable that has a Debug_Renaming_Link.
4007 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
4008 special type to be associated with variables that provide debugger

4012 Ed Schonberg <schonberg@adacore.com>
4013 Javier Miranda <miranda@adacore.com>
4015 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
4016 ancestor part given by an aggregate to test for an unchecked conversion,
4017 since this can occur in some cases when the ancestor part is a function
4018 call, and we don't want to fall into the recursive call to this
4019 procedure in that case.
4021 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
4022 stream attributes on limited types to account for user-specified
4023 attributes as well as whether Input (resp. Output) becomes available
4024 due to Read (resp. Write) being available for the type. Change Boolean
4025 variable to the more accurate name
4026 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
4027 double-"not" predicate at beginning of return statement to more
4028 understandable form.
4030 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
4031 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
4032 in a block statement and use that as the first statement of the
4033 expanded return rather than incorrectly using the handled sequence as
4034 the first statement.
4036 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
4037 operation, generate an explicit freeze node for it rather than
4038 generating extra formals, to ensure that gigi has the proper order of
4039 elaboration for anonymous subtypes in the signature of the subprograms.
4040 (Build_In_Place_Formal): Move assertion to beginning of loop.
4041 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
4042 applied to a function call (occurs for some cases of 'Input).
4043 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
4044 applied to a function call (occurs for some cases of 'Input).
4046 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
4047 2005, generate an extended return statement enclosing the result object
4050 * freeze.adb (Freeze_Record_Type): Extend the current management of
4051 components that are access type with an allocator as default value: add
4052 missing support to the use of qualified expressions of the
4053 allocator (which also cause freezing of the designated type!)
4054 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
4055 dispatching operation, since extra formals may be needed by calls to
4056 build-in-place functions (such as stream 'Input).
4058 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
4059 formals for 'Constrained and accessibility level in the case of a
4060 predefined dispatching operation.
4062 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
4063 point, no need to find the parent node.
4065 2007-08-16 Javier Miranda <miranda@adacore.com>
4067 * exp_attr.adb (Attribute_Priority): Add missing support for entries
4070 2007-08-16 Javier Miranda <miranda@adacore.com>
4072 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
4073 is not really required and can introduce regression with the debugger.
4074 The original problem is fixed with the patch written for checks.adb.
4076 2007-08-16 Thomas Quinot <quinot@adacore.com>
4078 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
4079 Range_Check on Allocated_Table.

4083 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
4084 Including_Non_Switch set to False.
4085 (Gnatmake): For the compiler, call Test_If_Relative_Path with
4086 Including_Non_Switch set to False.
4088 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
4089 parameter Including_Non_Switch, defaulted to True. When
4090 Including_Non_Switch is False, options that are not switches and
4091 appear as relative path are not converted to absolute paths.
4093 2007-08-16 Nicolas Roche <roche@adacore.com>
4095 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
4098 * Make-lang.in: Update dependencies

4103 currently inspected is a selected component, retrieve the entity of
4105 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
4106 from the immediate ancestor of Main_Unit_Entity.
4107 (Install_Limited_Withed_Unit): Do not install the limited view of
4108 package P if P is reachable through an ancestor chain from package C
4109 and C also has a with clause for P in its body.
4110 (Has_Limited_With_Clause): New routine.
4111 (Has_With_Clause): New routine.
4113 2007-08-16 Ed Schonberg <schonberg@adacore.com>
4115 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
4116 generic for an enclosing instance is a global reference, even though
4117 its scope is the enclosing instance.
4119 2007-08-16 Gary Dismukes <dismukes@adacore.com>
4120 Javier Miranda <miranda@adacore.com>
4122 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
4123 initialize a limited object.
4124 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
4126 Make sure Has_Complex_Representation is inherited by derived type.
4128 2007-08-16 Robert Dewar <dewar@adacore.com>
4130 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
4133 2007-08-16 Ed Schonberg <schonberg@adacore.com>
4135 * sem_disp.adb (Check_Dispatching_Operation): If the operation
4136 implements an operation inherited from a progenitor interface, verify
4137 that they are subtype-conformant.
4139 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
4140 Bob Duff <duff@adacore.com>
4141 Nicolas Setton <setton@adacore.com>
4143 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
4144 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
4145 the statement which is being resolved comes from a predefined library
4146 unit, all non-predefined library interpretations are skipped.
4147 (Resolve_Op_Concat): If string concatenation was folded in the parser,
4148 but the "&" is user defined, give an error, because the folding would
4151 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
4152 the parser has folded a long sequence of concatenations of string
4155 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
4156 and "JMP_BUF" variables as artificial.
4157 (N_String_Literal): Do not use alloca for very long string literals. Use
4158 xmalloc/free instead. Otherwise the stack might overflow.
4160 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
4163 2007-08-16 Vincent Celier <celier@adacore.com>
4165 * vms_conv.adb (Process_Argument): Ensure that project related options
4166 are not put in the -cargs section when using GNAT COMPILE.
4168 2007-08-16 Robert Dewar <dewar@adacore.com>
4170 * gnat_ugn.texi: Add note on preprocessing (output file not written)
4172 2007-08-16 Thomas Quinot <quinot@adacore.com>
4174 * a-tags.adb: Minor reformatting.

4187 * a-calend-vms.adb, a-calend.adb ("+", "-", Add, Subtract): Remove
4188 calls to Check_Within_Time_Bounds.
4189 ("+", "-", Add, Subtract): Remove calls to Check_Within_Time_Bounds.
4190 (Difference): Account for possible rounding of the resulting difference

4196 s-osinte-solaris.adb, s-osinte-solaris.ads,
4197 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.
4199 * styleg.adb, styleg.ads, stylesw.adb, stylesw.ads: implement style
4200 switch -gnatyS. Enable -gnatyS in GNAT style check mode
4202 2007-08-14 Robert Dewar <dewar@adacore.com>
4203 Ed Schonberg <schonberg@adacore.com>
4205 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
4206 Suppress unmodified in-out parameter warning in some cases
4207 This patch is a also fairly significant change to the way suppressible
4210 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
4211 needed for access to concurrent record types generated by the expander.
4212 (Generate_Range_Check): When generating a temporary to capture the
4213 value of a conversion that requires a range check, set the type of the
4214 temporary before rewriting the node, so that the type is always
4215 properly placed for back-end use.
4216 (Apply_Float_Conversion_Check): Handle case where the conversion is
4218 (Get_Discriminal): Code reformatting. Climb the scope stack looking
4219 for a protected type in order to examine its discriminants.
4221 2007-08-14 Robert Dewar <dewar@adacore.com>
4222 Gary Dismukes <dismukes@adacore.com>
4223 Ed Schonberg <schonberg@adacore.com>
4224 Thomas Quinot <quinot@adacore.com>
4226 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
4227 a-stwisu.adb, a-strsup.adb: Fix warnings for range
4228 tests optimized out.
4230 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
4231 (Get_Allocator_Final_List): For the case of an anonymous access type
4232 that has a specified Associated_Final_Chain, do not go up to the
4234 (Expand_N_Type_Conversion): Test for the case of renamings of access
4235 parameters when deciding whether to apply a run-time accessibility
4237 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
4238 aggregate code before allocator, and ahead of declaration for
4239 temporary, to prevent access before elaboration when the allocator is
4240 an actual for an access parameter.
4241 (Expand_N_Type_Conversion): On an access type conversion involving an
4242 access parameter, do not apply an accessibility check when the
4243 operand's original node was an attribute other than 'Access. We now
4244 create access conversions for the expansion of 'Unchecked_Access and
4245 'Unrestricted_Access in certain cases and clearly accessibility should
4246 not be checked for those.
4248 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
4249 includes a type conversion of a packed component that has been expanded,
4250 recover the original expression for the object, and use this expression
4251 in the post-call assignment statement, so that the assignment is made
4252 to the object and not to a back-end temporary.
4253 (Freeze_Subprogram): In case of primitives of tagged types not defined
4254 at the library level force generation of code to register the primitive
4255 in the dispatch table. In addition some code reorganization has been
4256 done to leave the implementation clear.
4257 (Expand_Call): When expanding an inherited implicit conversion,
4258 preserve the type of the inherited function after the intrinsic
4259 operation has been expanded.
4261 * exp_ch2.ads, exp_ch2.adb
4262 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
4263 of an entry formal appearing in an assignment statement does not assign
4265 (Expand_Current_Value): Instead of calling a routine to determine
4266 whether the prefix of an attribute reference should be optimized or
4267 not, prevent the optimization of such prefixes all together.
4269 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
4270 component whose prefix is known to be of an access type is an implicit
4271 dereference and does not assign to the prefix.
4273 2007-08-14 Ed Schonberg <schonberg@adacore.com>
4274 Robert Dewar <dewar@adacore.com>
4276 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
4277 itype is visited, make an entry into table to link associated node and
4279 Add comments and correct harmless error in Build_NCT_Hash_Tables
4280 (Array_Aggr_Subtype): Associate each itype created for an index type to
4281 the corresponding range construct, and not to the aggregate itself. to
4282 maintain a one-to-one correspondence between itype and its associated
4283 node, to prevent errors when complex expression is copied.
4284 Fix mishandling of multiple levels of parens
4286 * sem_aggr.adb: Create a limited view of an incomplete type, to make
4287 treatment of limited views uniform for all visible declarations in a
4288 limited_withed package.
4289 (New_Copy_Tree): If hash table is being used and itype is visited,
4290 make an entry into table to link associated node and new itype.
4291 (Resolve_Record_Aggregate): Do not add an others box association for a
4292 discriminated record component that has only discriminants, when there
4293 is a box association for the component itself.
4295 * par-ch4.adb: Fix mishandling of multiple levels of parens
4297 2007-08-14 Robert Dewar <dewar@adacore.com>
4299 * comperr.adb: Fix problem with suppressing warning messages from gigi
4301 * erroutc.ads, erroutc.adb, errout.ads,
4302 errout.adb (Write_Eol): Remove trailing spaces before writing the line
4303 (Write_Eol_Keep_Blanks): New procedure to write a line, including
4304 possible trailing spaces.
4305 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
4306 Fix problem with suppressing warning messages from back end
4307 Improve handling of deleted warnings
4310 Fix problem with suppressing warning messages from back end
4311 Handle setting of Static_Dispatch_Tables flag.
4314 Fix problem with suppressing warning messages from back end
4316 * exp_intr.adb: Improve handling of deleted warnings
4318 2007-08-14 Robert Dewar <dewar@adacore.com>

4330 Javier Miranda <miranda@adacore.com>
4331 Gary Dismukes <dismukes@adacore.com>
4333 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
4334 to make treatment of limited views uniform for all visible declarations
4335 in a limited_withed package.
4336 Improve warnings for in out parameters
4337 (Set_Related_Interaface/Related_Interface): Allow the use of this
4338 attribute with constants.
4339 (Write_Field26_Name): Handle attribute Related_Interface in constants.
4340 Warn on duplicate pragma Preelaborable_Initialialization
4342 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
4343 generation of a freezing node to ensure proper management of null
4344 excluding access types in the backend.
4345 (Create_Extra_Formals): Test base type of the formal when checking for
4346 the need to add an extra accessibility-level formal. Pass the entity E
4347 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
4348 originally being done in a couple of cases), to ensure that the
4349 Extra_Formals list gets set on the entity E when the first entity is
4351 (Conforming_Types): Add missing calls to Base_Type to the code that
4352 handles anonymous access types. This is required to handle the
4353 general case because Process_Formals builds internal subtype entities
4354 to handle null-excluding access types.
4355 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
4356 functions that need it, even when not marked Requires_Overriding.
4357 Improve warnings for in out parameters
4358 (Analyze_Function_Return): Warn for disallowed null return
4359 Warn on return from procedure with unset out parameter
4360 Ensure consistent use of # in error messages
4361 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
4362 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
4363 the implicit conversion of the expression done for anonymous access
4364 types. This is required to generate the code of the null excluding
4365 check (if required).
4367 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
4368 A formal parameter is never publicly referenceable outside of its body.
4369 (Check_References): For an unreferenced formal parameter in an accept
4370 statement, use the same warning circuitry as for subprogram formal
4372 (Warn_On_Unreferenced_Entity): New subprogram, taken from
4373 Output_Unreferenced_Messages, containing the part of that routine that
4374 is now reused for entry formals as described above.
4375 (Goto_Spec_Entity): New function
4376 (Check_References): Do not give IN OUT warning for dispatching operation
4377 Improve warnings for in out parameters
4378 (Test_Ref): Check that the entity is not undefinite before calling
4379 Scope_Within, in order to avoid infinite loops.
4380 Warn on return from procedure with unset out parameter
4381 Improved warnings for unused variables

4385 Gary Dismukes <dismukes@adacore.com>
4387 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
4388 (Expand_N_Attribute_Reference): Further unify the handling of the
4389 three forms of access attributes, using common code now for all three
4390 cases. Add a test for the case of applying an access attribute to
4391 an explicit dereference when the context is an access-to-interface
4392 type. In that case we need to apply the conversion to the prefix
4393 of the explicit dereference rather than the prefix of the attribute.
4394 (Attribute_Version, UET_Address): Set entity as internal to ensure
4395 proper dg output of implicit importation.
4396 (Expand_Access_To_Type): Removed.
4397 (Expand_N_Attribute_Reference): Merge the code from the three cases
4398 of access attributes, since the processing is largely identical for
4399 these cases. The substantive fix here is to process the case of a
4400 type name prefix (current instance case) before handling the case
4401 of interface prefixes.

4405 Javier Miranda <miranda@adacore.com>
4406 Robert Dewar <dewar@adacore.com>
4408 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
4409 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
4410 type that is an anonymous access to controlled object, establish
4411 an associated finalization chain to avoid corrupting the global
4412 finalization list when a dynamically allocated object designated
4413 by such a component is deallocated.
4414 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
4415 functions that need it, even when not marked Requires_Overriding.
4416 (Initialize_Tag): Replace call to has_discriminants by call to
4417 Is_Variable_Size_Record in the circuitry that handles the
4418 initialization of secondary tags.
4419 (Is_Variable_Size_Record): New implementation.
4420 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
4421 Suppress_Initialization pragma for a derived type.
4422 (Is_Variable_Size_Record): New subprogram.
4423 (Build_Offset_To_Top_Functions): New implementation that simplifies the
4424 initial version of this routine and also fixes problems causing
4425 incomplete initialization of the table of interfaces.
4426 (Build_Init_Procedure): Improve the generation of code to initialize the
4427 the tag components of secondary dispatch tables.
4428 (Init_Secondary_Tags): New implementation that simplifies the previous
4429 version of this routine.

4487 Thunk_Alias which is no longer required, cleanup evaluation of the
4488 the controlling type, and update the documentation.

4513 * exp_util.ads, exp_util.adb:
4514 This patch replaces a number of occurrences of explicit tests for N_Null
4515 with calls to Known_Null. This improves tracking of null values, since
4516 Known_Null also catches null constants, and variables currently known to
4517 be null, so we get better tracking.
4518 (Ensure_Defined): create an itype reference only in the scope of the
4520 (Side_Effect_Free): A selected component of an access type that
4521 denotes a component with a rep clause must be treated as not

4523 value may be affected by a renaming.
4524 (Expand_Subtype_From_Expr): For limited objects initialized with build
4525 in place function calls, do nothing; otherwise we prematurely introduce
4526 an N_Reference node in the expression initializing the object, which
4527 breaks the circuitry that detects and adds the additional arguments to
4528 the called function. Bug found working in the new patch for statically
4529 allocated dispatch tables.
4530 (Is_Library_Level_Tagged_Type): New subprogram.

4534 attributes properly to compute the constraint on the resulting aggregate
4537 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
4538 class-wide type whose base type is an incomplete private type, leave
4539 class-wide type unfrozen so that freeze nodes can be generated
4540 properly at a later point.
4541 (Freeze_Entity, array case): Handle case of pragma Pack and component
4542 size attributre clause for same array.

5191 operations in Derive_Subprograms.
5192 (Collect_Previous_Instances): new procedure within of
5193 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
5194 unit being loaded, to ensure that the generation of global symbols is
5195 consistent in different compilation modes.
5196 (Is_Tagged_Ancestor): New function testing the ancestor relation that
5197 takes progenitor types into account.
5198 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
5199 traversing over the primitives of the formal and actual types to locate
5200 any abstract subprograms of the actual type that correspond to a
5201 nonabstract subprogram of the formal type's ancestor type(s), and issue
5202 an error if such is found.
5203 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
5204 Instantiate_Package_Body, Instantiate_Subprogram_Body):
5205 Remove bogus guard around calls to Inherit_Context.

5217 controlling formal is not an in_parameter, reject the actual if it is
5218 an access_to_constant type.
5219 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
5220 type, the candidate operations are found in the scope of declaration of
5221 the type, because the type has no primitive subprograms.
5222 (Analyze_Selected_Component): If prefix is class-wide, and root type is
5223 a private extension, only examine visible components before trying to
5224 analyze as a prefixed call.
5225 Change Entity_List to Type_To_Use, for better readability.
5226 (Has_Fixed_Op): Use base type when checking whether the type of an
5227 operator has a user-defined multiplication/division
5228 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when

5235 formal At_Any_Place indicating, when True, that we want to test for
5236 availability of the stream attribute at any place (as opposed to the
5237 current visibility context only).
5238 (Missing_Read_Write_Attributes): A stream attribute is missing for the
5239 purpose of enforcing E.2.2(8) only if it is not available at any place.
5240 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
5241 when checking the legality of an extension aggregate in a preelaborable
5242 package. Treat the literal null as a valid default expression in a
5243 component declaration for a type with preelaborable initialization.
5244 A limited interface is a legal progenitor for the designated type of a
5245 remote access to class-wide type.

5259 views that are themselves incomplete types.
5260 Handle interfaces visible through limited-with clauses.
5261 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
5262 subprogram generic actual for which we have generated a renaming.

5270 appear in the subtree to the current allocator if it is not a static
5272 (Resolve_Allocator): Perform cleanup if resolution has determined that
5273 the allocator is not a coextension.
5274 (Resolve): Skip an interpretation hidden by an abstract operator only
5275 when the type of the interpretation matches that of the context.
5276 (Resolve): When looping through all possible interpretations of a node,
5277 do not consider those that are hidden by abstract operators.
5278 (Resolve_Actuals): When verifying that an access to class-wide object
5279 is an actual for a controlling formal, ignore anonymous access to
5280 subprograms whose return type is an access to class_wide type.
5281 (Resolve_Slice): If the prefix of the slice is a selected component
5282 whose type depends on discriminants, build its actual subtype before
5283 applying range checks on the bounds of the slice.
5284 (Valid_Conversion): In an instance or inlined body, compare root types,
5285 to prevent anomalies between private and public views.

5307 elabration statements, register the package with the name server
5308 at the beginning, not at the end, of the elaboration statements so
5309 that they can create remote access to subprogram values that designate
5310 remote subprograms from the package.

5314 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
5315 values to compute the number of seconds since the Unix Epoc in order to
5316 account for Daylight Savings Time. Perform special processing for dates
5317 that are earlier than the Unix Epoc to obtain a negative number.

6402 System_Restrictions and initialization of the data unless there is
6403 some use of System.Restrictions in the partition.
6404 (Check_System_Restrictions_Used): New procedure
6406 * s-stalib.adb: Remove with of System.Restrictions. No longer needed
6407 since we only with this unit in the binder file if it is used elsewhere

6436 (Get_E_Length): Protect against bomb in case scope is standard

6439 bounds of the slice to construct the required constraint checks.
6440 Improve NOT NULL error messages
6441 (Apply_Constraint_Check): If the context is a null-excluding access

6457 Eric Botcazou <ebotcazou@adacore.com>
6458 Arnaud Charlet <charlet@adacore.com>
6460 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
6461 applicable to types that have the With_Type flag set. Returns the
6462 non-limited view of the type, if available, otherwise the type itself.
6463 For class-wide types, there is no direct link in the tree, so we have
6464 to retrieve the class-wide type of the non-limited view of the Etype.
6465 New attributes Static_Initialization and Static_Elaboration_Desired.
6466 Remove the pragma Thread_Body, and the associated flag
6467 Is_Thread_Body in entities, and all related code.
6468 (Suppress_Value_Tracking_On_Call): New flag

6477 components of records. Set to point to the entity of the corresponding
6479 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
6480 (Original_Access_Type): Remove, not needed.
6481 (Root_Type): Handle properly subtypes of class-wide-types.
6484 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
6485 class-wide types visible through limited-with clauses.
6486 (Try_Primitive_Operation): When examining all primitive operations of a
6487 tagged type, do not consider subprograms labeled as hidden unless they
6488 belong to a private generic type with a tagged parent.
6489 (Try_Object_Operation): Extensive rewriting, to handle properly various
6490 overloading cases, when several ancestors may have class-wide operations
6491 that are possible candidates, and when the overloaded functions return
6492 array types and have defaulted parameters so that the call may be
6493 interpreted as an indexing.
6494 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
6495 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
6496 successive actuals before analyzing the call itself.
6497 (Try_Primitive_Operation): A primitive operation is compatible with the
6498 prefix if the prefix has a synchronized type and the type of the formal
6499 is its corresponding record, as can be the case when the primitive
6500 operation is declared outside of the body of the type.
6501 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
6502 perform homonym traversal, looking for class-wide operation matches
6503 (formerly done in statements of Try_Class_Wide_Operation). Matches on
6504 access parameters are now restricted to anonymous access types.
6505 (Mark_Allocator): An allocator with a discriminant association parent is
6507 (Try_One_Prefix_Interpretation): If the type of the object is
6508 incomplete, as can be happen when it is a limited view obtained through
6509 a limited_with_clause, the selected component is not part of a prefixed
6511 (Complete_Object_Operation): Diagnose properly an object that is not
6512 aliased when the corresponding controlling formal is an access
6514 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
6515 ambiguous calls in prefixed notation, where two primitives differ only
6516 in that the controlling argument of one is an access parameter.
6518 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
6519 whether a function that returns an unconstrained type can be inlined.
6520 (Process_Formals): Diagnose properly the illegal use of an incomplete
6521 type in the profile of an access_to_subprogram declaration.
6522 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
6523 operations are attached to the corresponding record.
6524 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
6525 When processing a primitive of a concurrent type which implements an
6526 interface change the type of all controlling formals to that of the
6527 corresponding record type.
6528 (Check_Synchronized_Overriding): Relax the conditional logic when trying
6529 to determine the tagged type to which a primitive belongs.
6530 (Check_Conventions): Capture condition to ignore a primitive operation
6531 (which is shared between the loop in Check_Conventions and the one in
6532 Check_Convention) in a new local function Skip_Check.
6533 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
6534 confusion with Check_Conventions' own Prim_Op local variable.
6535 (Create_Extra_Formals): Test for a tagged result type rather than a
6536 controlling result when determining whether to add a BIP_Alloc_Form
6537 formal and a BIP_Final_List formal to the function.
6538 (Check_Conformance); For parameters that are anonymous access types,
6539 subtype conformance requires that the not null and the constant
6540 indicators must match
6541 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
6542 to retrieve the appropriate type when processing a concurrent type
6543 declared within a generic. Minor comment reformatting. Change invocation
6544 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
6546 (Analyze_Subprogram_Body): If the return type of a function is an
6547 anonymous access to the limited view of a class-wide type, and the
6548 non-limited view of the type is available, update the type of the
6549 function so that code can be generated.
6550 (Process_Formals): In case of access-subtype itype whose designated
6551 type is also an itype (situation that happens now with access to
6552 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
6553 attribute to avoid backend problems.
6554 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
6555 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
6556 anonymous types' designated types are same before testing
6557 Subtypes_Statically_Match.
6558 (Create_Extra_Formals): Test for a named access parameter that is a
6559 controlling formal as an additional condition for adding an
6560 accessibility level formal. This can occur in the subp type created for
6561 dispatching calls in Expand_Dispatching_Call, and allows calling
6562 Create_Extra_Formals from that procedure rather than special-casing the
6563 extra formals there.
6564 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
6565 when the function has a controlling result.
6566 (Check_Returns): Add much more knowledge of the optimization of local
6567 raise statements to gotos, to retain proper warnings in this case.
6568 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
6569 nodes when looking for last statement.
6571 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
6572 class-wide types visible through limited with clauses.
6573 (Add_One_Interp): If the operands are anonymous access types, the
6574 predefined operator on universal_access is immediately visibles
6575 (Find_Unique_Type): Handle anonymous access to subprogram types just as
6576 other anonymous access types.
6577 (Disambiguate): Take into account CIL convention.
6578 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
6580 2007-06-06 Robert Dewar <dewar@adacore.com>
6582 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
6583 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,

6585 Fix lower bound of tables.
6588 * nlists.adb: Ditto.
6589 (Prev_Node, Next_Node): Change index type to Int so that it properly
6590 covers the range First_Node_Id - 1 up.

6595 Hristian Kirtchev <kirtchev@adacore.com>
6597 * exp_aggr.ads, exp_aggr.adb:
6598 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
6599 in extension aggregates.
6600 (Flatten): Other conditions being met, an aggregate is static if the
6601 low bound given by component associations is different from the low
6602 bound of the base index type.
6603 (Packed_Array_Aggregate_Handled): If the component type is itself a
6604 packed array or record, the front-end must expand into assignments.
6605 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
6606 Init_Pr, instead of Ancestor_Is_Expression.
6607 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
6608 coextension chain root, either generate a list controller or use the
6609 already existing one.
6610 (Static_Array_Aggregate): New procedure to construct a positional
6611 aggregate that can be handled by the backend, when all bounds and
6612 components are compile-time known constants.
6613 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
6614 types covering interface types into assignments.
6615 (Replace_Type): move to Build_Record_Aggr_Code.
6616 (Expand_Record_Aggr_Code): if the target of the aggregate is an
6617 interface type, convert to the definite type of the aggregate itself,
6618 so that needed components are visible.
6619 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
6620 components and the context is an extended return statement do not
6621 create a transient block for it, to prevent premature finalization
6622 before the return is executed.
6623 (Gen_Assign): Do not generate a call to deep adjust routine if the
6624 component type is itself an array of controlled (sub)-components
6625 initialized with an inner aggregate.
6626 (Component_Check): New name for Static_Check. This name is now more
6627 appropriate, and documentation is added which was missing.
6628 (Component_Check): Add test for bit aligned component value
6629 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
6630 Tagged_Comps, name is more appropriate given added function below.
6631 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

6638 Terminated: Add unchecked type conversion from System.Address to
6639 System.Tasking.Task_Id when calling the predefined primitive
6641 Disable new Ada 05 accessibility check for JVM.NET targets, which
6642 cannot be implemented in a practical way.
6643 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
6644 the sources always references the tag of the actual object. Therefore,
6645 if 'Tag is applied in the sources to class-wide interface objects we
6646 generate code that displaces "this" to reference the base of the object.
6647 (Expand_N_Attribute_Reference, case Size): Return specified size if
6649 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
6650 has code that displaces the pointer of the object to manage interface
6651 types. However this code must not be executed when the prefix is a
6652 subprogram. This bug caused the wrong expansion of the internally
6653 generated assignment that fills the dispatch table when the primitive
6654 is a function returning a class-wide interface type.
6655 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
6656 Set_Attribute_Name for Name_Unaligned_Valid.
6658 2007-06-06 Ed Schonberg <schonberg@adacore.com>

6661 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
6662 If the initialization is the equivalent aggregate of the initialization
6663 procedure of the type, do not remove it.
6664 (Expand_N_Attribute_Definition_Clause): Exclude access variables
6665 initialized to null from having their expression reset to empty and
6666 note this exception in the comment.

6687 (Analyze_Attribute, case 'Access): If the type of the prefix is a
6688 constrained subtype for a nominal unconstrained type, use its base type
6689 to check for conformance with the context.
6690 (Resolve_Attribute): Remove test of the access type being associated
6691 with a return statement from condition for performing accessibility
6692 checks on access attributes, since this case is now captured by
6693 Is_Local_Anonymous_Access.
6694 (Analyze_Access_Attribute): Set Address_Taken on entity
6695 (Analyze_Attribute, case Address): Set Address_Taken on entity
6696 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
6697 validating an access attribute whose prefix is a current instance.
6698 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
6699 applied to dispatching operations, if freezing is required then we set
6700 the attribute Has_Delayed_Freeze in the prefix's entity.
6701 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
6702 current scope if access of local subprogram taken
6703 (Analyze_Access_Attribute): Check legality of self-reference even if the
6704 expression comes from source, as when a single component association in
6705 an aggregate has a box association.
6706 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
6707 the prefix if it is a protected operation and the attribute is
6708 Unrestricted_Access.
6709 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
6710 reference to the base type of the context, to force a constraint check
6711 when the context is an access subtype with an explicit constraint.
6712 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
6713 node is rewritten as an interface conversion. leave unanalyzed after
6714 resolution, to ensure that type checking against the context will take

6718 Javier Miranda <miranda@adacore.com>
6719 Robert Dewar <dewar@adacore.com>
6721 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
6722 wrapper when the full view of the controlling type of an inherited
6723 function that dispatches on result implements interfaces.
6724 (Expand_N_Object_Declaration): In cases where the type of the
6725 declaration is anonymous access, create finalization list for it.
6726 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
6727 if the object has no explicit initialization, to match description of
6728 functionality of pragam Persistent_BSS.
6729 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
6730 new function to build static aggregates, to replace initialization call
6731 when static initialization is desired.
6732 (Freeze_Type): Generate a list controller for an access type whenever
6733 its designated type has controlled anonymous access discriminants.
6734 (Build_Equivalent_Aggregate): New procedure to compute a static
6735 aggregate to be used as default initialization for composite types,
6736 instead of a generating a call to the initialization procedure for the
6738 (Build_Initialization_Call): When available, replace a call to the
6739 initialization procedure with a copy of the equivalent static aggregate
6741 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
6742 declarations for objects of a class-wide interface type, rather than
6743 just identifiers, to prevent visibility problems.
6744 (Expand_N_Object_Declaration): When expanding the declaration for an
6745 object of a class-wide interface type, preserve the homonym chain of
6746 the original entity before exchanging it with that of the generated
6747 renaming declaration.
6748 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
6749 active, because there is no way to handle the exception.
6750 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
6751 to do a minimum decoration of the Access_Disp_Table list.
6752 (Expand_Record_Controller): Avoid the addition of the controller between
6753 the component containing the tag of a secondary dispatch table and its
6754 adjacent component that stores the offset to the base of the object.
6755 This latter component is only generated when the parent type has
6756 discriminants ---documented in Add_Interface_Tag_Components).
6757 (Apply_Array_Size_Check): Removed, no longer needed.
6758 (Expand_N_Full_Type_Declaration): If the type has anonymous access
6759 components, create a Master_Entity for it only if it contains tasks.
6760 (Build_Init_Procedure): Suppress the tag assignment compiling under
6762 (Freeze_Record_Type): Remove code associated with creation of dispatch
6764 (Init_Secondary_Tags): Update type of actuals when generating calls to
6765 Ada.Tags.Set_Offset_To_Top
6766 (Stream_Operation_OK): Disable use of streams compiling under no
6768 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
6769 if Has_Init_Expression set.
6770 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
6771 Register_Primitive, which provides the same functionality.
6772 (Requires_Init_Proc): Return false in case of interface types.
6773 (Add_Secondary_Tables): Use the new attribute Related_Interface to
6775 (Predefined_Primitive_Freeze): Do not assume that an internal entity
6776 is always associated with a predefined primitive because the internal
6777 entities associated with interface types are not predefined primitives.
6778 Therefore, the call to Is_Internal is replaced by a call to the
6779 function Is_Predefined_Dispatching_Operation.
6780 (Make_Eq_If): When generating the list of comparisons for the
6781 components of a given variant, omit the controller component that is
6782 present if the variant has controlled components.
6784 2007-06-06 Javier Miranda <miranda@adacore.com>
6785 Hristian Kirtchev <kirtchev@adacore.com>
6786 Bob Duff <duff@adacore.com>
6788 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
6789 handle the creation of finalization lists and calls for nested
6790 coextensions when the root of the chains is part of a return statement.
6791 (Inside_A_Return_Statement): New function inside Complete_Coextension_
6793 (Expand_Record_Equality): Skip components that are interface types.
6794 (Displace_Allocator_Pointer): Add missing support for interface subtypes
6795 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
6796 with Rewrite_Coextension. Change the condition for detecting coextension
6798 (Is_Local_Access_Discriminant): Removed.
6799 (Rewrite_Coextension): New routine which rewrites a static coextension
6800 as a temporary and uses its unrestricted access in the construction of
6802 (Complete_Coextension_Finalization): New routine. Generate finalization
6803 attachment calls to all delayed coextensions.
6804 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
6805 the allocator is not a coextension itself and has delayed coextensions.
6806 If the current allocator is controlled, but also a coextension, delay
6807 the generation of the finalization attachment call.
6808 Rename local variable "Node" to "Nod" in order to avoid confusion with
6810 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
6811 limited types that are not inherently limited. Such an allocator is
6812 illegal, but is generated by the expander for a return statement, to
6813 copy the result onto the secondary stack. This is the only case where a
6814 limited object can be copied. Generate code to displace the pointer
6815 to the object if the qualified expression is a class-wide interface
6816 object. Such displacement was missing and hence the copy of the object
6818 (Apply_Accessibility_Check): Handle allocated objects initialized in
6820 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
6821 and Expand_Allocator_Expression. Allocating class-wide interface objects
6822 this routine displaces the pointer to the allocated object to reference
6823 the component referencing the corresponding secondary dispatch table.
6824 Expand_Allocator_Expression): Add missing support to allocate class-wide
6825 interface objects initialized with a qualified expression.
6826 (Get_Allocator_Final_List): Test for an anonymous access type that is a
6827 function result type, and use the finalization list associated with the
6828 function scope in that case (such an anonymous type should not be
6829 treated like an access parameter's type).
6831 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6832 Gary Dismukes <dismukes@adacore.com>
6833 Javier Miranda <miranda@adacore.com>
6835 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
6836 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
6837 required exception handler.
6838 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
6839 properly the case of a function whose return type is a limited
6840 class-wide interface type. Modify the code of the accessibility
6841 check to handle class-wide interface objects. In this case we need to
6842 displace "this" to reference the primary dispatch table to get access
6843 to the TSD of the object (to evaluate its accessibility level).
6844 (Expand_N_Extended_Return_Statement): Test for a tagged result type
6845 rather than a controlling result as one of the conditions for
6846 generating tests of the implicit BIP_Alloc_Form formal. The
6847 initialization assignment is also handled according to whether the
6848 result is tagged instead of controlling.
6849 In the case where the init assignment is inserted in the "then" part of
6850 the allocation conditional, rewrite the target to be a dereference of
6851 the implicit BIP_Object_Access formal.
6852 If the returned value is unconstrained and created on the secondary
6853 stack, mark the enclosing block and function so that the secondary
6854 stack is not reclaimed on return.
6855 Treat returns from functions with controlling results similarly to
6856 returns from functions with unconstrained result subtypes.
6857 If the object returned is unconstrained, and an allocator must be
6858 created for it, analyze the allocator once the block for the extended
6859 return is installed, to ensure that finalizable components
6860 of the expression use the proper finalization list. Guard the call to
6861 Move_Final_List with a check that there is something to finalize.
6862 (Make_Tag_Ctrl_Assignment): Use "old" handling
6863 of controlled type assignment for virtual machines, since new code uses
6864 unsupported features (such as direct access to bytes in memory).
6866 2007-06-06 Gary Dismukes <dismukes@adacore.com>
6867 Ed Schonberg <schonberg@adacore.com>
6869 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
6870 accessibility actual, check for the case of an aliased object that has
6871 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
6872 we fall into processing for the attribute rather than the name of the
6874 (Expand_Inline_Call): If an actual is a literal, and the corresponding
6875 formal has its address taken in the body, create a temporary to capture
6876 value. If the return type is a limited interface, do not treat the
6877 return value as Controlled.
6878 (Is_In_Place_Function): If the return type is a limited interface,
6879 treat as returning in place. The actual returned object may not always
6880 be limited, but the caller has to assume that it is returned in place.
6881 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
6882 context of an allocator, use the correct finalization chain (that is,
6883 the chain belonging to the access type, rather than the chain belonging
6884 to the current scope).
6885 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
6886 result type rather than a controlling result as a precondition for
6887 adding an allocation form actual to a build-in-place call.
6888 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
6889 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
6890 primitive in the dispatch tables. This work is now done by Make_DT when
6892 (Register_Predefined_DT_Entry): Removed.
6893 (Add_Return): If end label is not present, use sloc of last statement
6894 for generated return statement in procedure, for better gdb behavior
6896 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
6897 object address nodes to ensure proper processing by routines like
6899 (Expand_Call): Fix generation of validity check for parameter
6900 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
6901 the allocation form parameter if the result subtype is constrained,
6902 except when the function has a controlling result.
6903 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
6904 rather than Is_Controlled and Has_Controlled_Component, since we want to
6905 include class-wide result types in this treatment. Also test for a
6906 controlling result, since that also requires passing a finalization
6908 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
6909 even when the result subtype is constrained, to handle calls involving
6910 controlling results.
6911 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
6912 is now called even when the result subtype is constrained, to handle
6913 calls involving controlling results.
6914 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
6915 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
6916 now performs the test).
6917 (Make_Build_In_Place_Call_In_Object_Declaration):
6918 Add_Alloc_Form_Actual_* is now called even when the result subtype is
6919 constrained, to handle calls involving controlling results.
6920 (Add_Return): Accomodate rewritten pattern from local raise to goto
6921 transformation, so that we still recognize an transfer statement
6922 and do the right thing here in that case.
6923 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
6924 and end of subprogram code.
6925 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
6926 support for primitives that are functions (without formals) with a
6928 (Inherited_From_Formal): If the actual subtype has not generic parent
6929 type, it is not an actual for a formal derived type, and there is no
6930 operation to inherit from the formal.
6932 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6933 Thomas Quinot <quinot@adacore.com>
6935 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
6936 inserted cleanup code appropriately for GDB use.
6937 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
6938 exception handler for Deep_Adjust or Deep_Finalize.
6939 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
6940 Raise_From_Controlled_Operation is available, use a call to that
6941 subprogram instead of a plain "raise Program_Error" node to raise
6942 Program_Error if an exception is propagated from an Adjust or Finalize
6944 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
6945 appears in the optional statement list of a triggering alternative, the
6946 scope actions can be inserted directly there, and not in the list that
6947 includes the asynchronous select itself.
6949 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6950 Robert Dewar <dewar@adacore.com>
6951 Hristian Kirtchev <kirtchev@adacore.com>
6953 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
6954 generated exception handler appropriately when debugging generated code.
6955 Deal properly with No_Exception_Propagation restriction mode.
6956 (Expand_N_Abort_Statement): Add an unchecked type conversion from
6957 System.Address to System.Tasking.Task_Id when processing the result of
6958 the predefined primitive _disp_get_task_id.
6959 (Expand_N_Asynchronous_Select): Clarify comment.
6960 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
6961 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
6962 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
6963 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
6964 privals and for generated call to Complete_Entry_Body, for better gdb
6966 (Copy_Result_Type): Utility to construct a parameter and result profile
6967 for protected functions whose return type is an anonymous access to
6969 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
6971 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
6972 point when the local-raise-to-goto transformation has taken place.
6974 2007-06-06 Javier Miranda <miranda@adacore.com>
6975 Nicolas Setton <setton@adacore.com>
6977 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
6978 functionality when the backend is generating code.
6979 Otherwise any serious error
6980 reported by the backend calling the frontend routine Error_Msg
6981 changes the Compilation_Mode to Check_Semantics, disables the
6982 functionality of this routine and causes the generation of
6983 spureous additional errors.
6985 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
6986 debugging information now generated by the compiler for fat-pointer
6988 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
6990 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
6992 2007-06-06 Thomas Quinot <quinot@adacore.com>

6995 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
6996 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
6997 For a remote call to a function with a classwide return type, apply an
6998 E.4(18) check to the returned value.
6999 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
7000 stream attributes of the designated type of an RACW, as they are not
7001 dispatching primitive operations.
7003 2007-06-06 Geert Bosch <bosch@adacore.com>
7005 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
7007 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
7009 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
7010 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
7012 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
7014 2007-06-06 Javier Miranda <miranda@adacore.com>
7016 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
7017 attribute compiling package Ada.Tags under No_Run_Time_Mode.
7019 2007-06-06 Javier Miranda <miranda@adacore.com>
7021 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
7022 deallocation of class-wide interface objects.
7023 (Expand_Dispatching_Constructor_Call): Take into account that if the
7024 result of the dispatching constructor is an interface type, the
7025 function returns a class-wide interface type; otherwise the returned
7026 object would be actual. The frontend previously accepted returning
7027 interface types because Expand_Interface_Actuals silently performed
7028 the management of the returned type "as if" it were a class-wide
7030 (Expand_Dispatching_Constructor_Call): Replace call to
7031 Make_DT_Access_Action by direct call to Make_Function_Call.
7033 2007-06-06 Robert Dewar <dewar@adacore.com>
7034 Ed Schonberg <schonberg@adacore.com>
7036 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
7037 compute masking constant, since we now set Esize properly to the
7039 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
7040 to match the alignment.
7041 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
7042 packed arrays of 8 bits or less.
7044 * freeze.adb (Freeze_Entity): When freezing the formals of a
7045 subprogram, freeze the designated type of a parameter of an access type
7046 only if it is an access parameter.
7047 Increase size of C convention enumeration object
7048 (Freeze_Entity, array type case): Make sure Esize value is properly
7049 adjusted for the alignment if it is known.
7050 (Freeze_Entity, array type case): When checking bit packed arrays for
7051 the size being incorrect, check RM_Size, not Esize.
7052 (Freeze_Record_Type): Check for bad discriminated record convention
7053 (In_Exp_Body): Return true if the body is generated for a subprogram
7054 renaming, either an attribute renaming or a renaming as body.
7055 (Check_Itype): If the designated type of an anonymous access component
7056 is a non-protected subprogram type, indicate that it is frozen, to
7057 prevent out-of-scope freeze node at some subsequent call.
7058 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
7059 only if the subprogram is neither imported nor exported, as well as the
7060 NCA descriptor class if the subprogram is exported.

7067 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
7068 default initialization on an imported object, when there is no
7069 initialization call generated for it.

7073 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
7074 Static_Elaboration_Desired.

7076 Implement a new pragma No_Body
7077 Removes the Explicit_Overriding pragma
7078 Remove Optional_Overriding pragma
7079 (Prag): Deal with Universal_Aliasing.
7080 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
7081 Pragma_CIL_Constructor): New names.
7083 * sem_cat.adb (Validate_Object_Declaration): An initialization that
7084 uses the equivalent aggregate of a type must be treated as an implicit
7086 (Get_Categorization): Check a unit for pragma Preelaborate only if it
7087 has none of the other categories.
7088 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
7089 to apply Import to an object renaming declaration.
7091 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
7092 from a C++ class should be declared as limited and that it will be
7093 considererd limited.
7094 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
7095 should be declared as limited and that it will be considererd limited.
7096 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
7097 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
7098 (Analyze_Pragma): Deal with Universal_Aliasing.
7099 (Sig_Flags): Likewise.
7100 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
7101 (Overflow_Checks_Unsuppressed): New flag.
7102 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
7103 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
7104 case of JVM or .NET targets, and compiling user code.
7105 Add debugging convenience routine rv
7107 2007-06-06 Robert Dewar <dewar@adacore.com>
7109 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
7111 (Build_Elementary_Input_Call): For floating-point use right type in the
7112 absence of strange size or stream size clauses.
7113 (Build_Elementary_Write_Call): Same fix
7114 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
7115 set to value that does not match base type size.
7117 2007-06-06 Ed Schonberg <schonberg@adacore.com>
7119 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
7120 object of a limited type can be initialized with a call to a function
7121 that returns in place. If the limited type has unknown discriminants,
7122 and the underlying type is a constrained composite type, build an actual
7123 subtype from the function call, as is done for private types.
7124 (Side_Effect_Free): An expression that is the renaming of an object or
7125 whose prefix is the renaming of a object, is not side-effect free
7126 because it may be assigned through the renaming and its value must be
7127 captured in a temporary.
7128 (Has_Controlled_Coextensions): New routine.
7129 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
7130 as is done for other limited types.
7131 (Non_Limited_Designated_Type): new predicate.

7134 Remove all handling of with_type clauses.
7136 * par-ch10.adb: Remove all handling of with_type clauses.
7138 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
7139 checksum if the main source could not be parsed.
7140 (Loat_Unit): When processing a child unit, determine properly whether
7141 the parent unit is a renaming when the parent is itself a child unit.
7142 Remove handling of with_type clauses.
7144 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

7152 Remove all handling of with_type clauses.
7153 (Exception_Junk): Can now be set in N_Block_Statement
7155 2007-06-06 Vincent Celier <celier@adacore.com>
7156 Robert Dewar <dewar@adacore.com>
7158 * frontend.adb (Frontend): Return immediately if the main source could
7159 not be parsed, because of preprocessing errors.
7161 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.
7162 (Gnat1drv): Exit with errors if the main source could not be parsed,
7163 because of preprocessing errors.

7176 2007-06-06 Robert Dewar <dewar@adacore.com>
7177 Ed Schonberg <schonberg@adacore.com>
7179 * g-comlin.ads, g-comlin.adb:
7180 Add new warning for renaming of function return objects
7182 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
7183 (Tree_Read): Use size of object instead of type'object_size, since the
7184 latter is incorrect for packed array types.
7185 (Tree_Write): Same fix
7187 * opt.ads: Add new warning for renaming of function return objects
7188 (Generating_Code): New boolean variable used to indicate that the
7189 frontend as finished its work and has called the backend to process
7190 the tree and generate the object file.
7191 (GCC_Version): Is now private

8758 the master of the created object is the innermost enclosing statement.

8786 required for a conversion between two access-to-unconstrained-array
8788 (Expr_Known_Valid): Validity checks do not apply to discriminants, but

9007 that use (a subtype of) the class-wide type of the enclosing type.

9010 Check_Anonymous_Access_Components rather than Empty.
9011 (Make_Incomplete_Type_Declaration): Add test for case where the type has
9012 a record extension in deciding whether to create a class-wide type,

9042 (Analyze_Subtype_Declaration): For an access subtype declaration, create
9043 an itype reference for the anonymous designated subtype, to prevent

9061 as the second switch, after -c.
9062 (Compile_Sources): Allow compilation of Annex J renames without -a
9063 (Is_In_Object_Directory): Check if the ALI file is in the object

9069 information, so that the correct GNAT tools will be used when spawned
9070 without directory information.

9096 there is no need to generate always a record_definition_node in case
9097 of synchronized interface types.
9098 (SIS_Entry_Active): Initialize global variable to False
9099 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

9120 If the array component is a discriminated record, the array aggregate
9121 is non-static even if the component is given by an aggregate with
9123 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
9124 (Convert_Aggr_In_Allocator): If the allocator is for an access
9125 discriminant and the type is controlled. do not place on a finalization
9126 list at this point. The proper list will be determined from the
9128 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
9129 initialize record controller if needed, before the components, to ensure
9130 that they are properly finalized.
9131 (Build_Record_Aggr_Code): For the case of an array component that has a
9132 corresponding array aggregate in the record aggregate, perform sliding

9142 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
9143 accessibility on class-wide allocators if the allocator occurs at the
9144 same scope level as the allocator's type. The check is guaranteed to
9145 succeed in that case, even when the expression originates from a
9146 parameter of the containing subprogram.
9147 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
9148 under No_Dispatching_Calls restriction. During the semantic analysis
9149 we already notified such violation.

9164 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
9166 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
9167 initialize most the TSD components by means of an aggregate.
9168 Modify the declaration of the object containing the TSD
9169 because we now expand code that has a higher level of abstraction.
9170 The TSD has a discriminant containing the Inheritance Depth Level,
9171 value that is used in the membership test but also to fix the size
9172 of the table of ancestors.
9173 (Expand_Interface_Conversion): Insert function body at the closest place
9174 to the conversion expression, to prevent access-before-elaboration
9175 errors in the backend.

9205 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
9206 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

9225 First/Next_Component_Or_Discriminant
9226 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
9227 (Find_Implemented_Interface): Removed. All the calls to this subprogram

9230 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
9231 support concurrent types implementing interfaces.
9232 (Find_Implemented_Interface): Removed. All the calls to this subprogram

9236 CW_Or_Controlled_Type whenever the issue is related to
9237 using or not the secondary stack.
9239 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
9240 P_Interface_Type_Definition to fulfill the new interface (the formal
9241 Is_Synchronized is no longer required).

9250 Cyrille Comar <comar@adacore.com>
9252 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
9253 anonymous, use finalization list of enclosing dynamic scope.
9254 (Expand_N_Package_Declaration): For a library package declaration
9255 without a corresponding body, generate RACW subprogram bodies in the
9256 spec (just as we do for the task activation call).
9257 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
9258 Is_Abstract_Type. Make sure these are called only when appropriate.
9259 Remove all code for DSP option

9276 Family_Size with 'Cap' set to true.
9277 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
9278 a protected version of an operation declared in the private part of
9279 a protected object, because they may be invoked through a callback.
9280 (Set_Privals): If the type of a private component is an anonymous access
9281 type, do not create a new itype for each protected body.
9282 If the body of a protected operation creates
9283 controlled types (including allocators for class-widetypes), the
9284 body of the corresponding protected subprogram must include a
9286 (Build_Activation_Chain_Entity): Build the chain entity for extended
9288 (Type_Conformant_Parameters): Use common predicate Conforming_Types
9289 to determine whether operation overrides an inherited primitive.

9303 Build_From_Any_Call.
9304 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
9305 E_Constant, depending upon Variable formal.
9306 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
9307 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
9308 parameter that requires an extra constrained parameter, declare
9309 temporary for actual as a variable, not a constant.
9310 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
9311 the unit being compiled is the one that contains the stub type.

9316 (Append_RACW_Bodies): New subprogram.
9317 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to

9320 statements in the HSS at the end of the pacakge.
9321 When expanding a package spec, this list correspond to the
9323 (Add_Receiving_Stubs_To_Declarations): Append the function
9324 registering the receiving stubs at the end of the 'Stmts' list.
9325 (RCI_Package_Locator): Pass the new Version generic formal when
9326 instantiating a RCI_Locator package.
9327 (Build_From_Any_Function): To compute the High bound for an
9328 unconstrained array actual, we add the Low bound with the length.
9329 Thus we must convert the low bound and the length to an appropriate
9330 type before doing the sum.
9331 (Build_Subprogram_Receiving_Stubs, PolyORB):
9332 * Retrieve the extra formals parameters at the
9333 end of the parameter stream.
9334 * Use Move_Any_Value to write back out parameters
9335 after executing the request as it is more efficient
9336 than Copy_Any_Value.
9337 * Build the any containing Extra Formals with the
9338 appropriate typecode.
9339 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
9340 empty Component_List.

9353 function with the first not implicit parent type.
9354 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
9355 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
9356 typecode from the Etype. Therefore we retrieve the correct typecode
9357 with a call to Get_Any_Type.
9358 (Copy_Specification): Do controlling formal type substitution based on
9359 Is_Controlling_Formal flag, instead of caller-provided object type.
9360 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
9361 a RACW primitive operation, we might get a subprogram declaration for an
9362 ancestor of the RACW designated type (not for the designated type
9363 itself), in the case where this operation is inherited. In this case we
9364 have no easy means of determining the original tagged type for which
9365 the primitive was declared, so instead we now rely on
9366 Copy_Specification to use the Is_Controlling_Formal flag to determine
9367 which formals require type substitution.

9373 GNAT.Current_Exception are not allowed if pragma Restrictions
9374 (No_Exception_Propagation) is set and in any case make the associated
9375 handler unsuitable as a target for a local raise statement.
9376 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
9377 run-time subprogram CW_Membership by call to Build_CW_Membership.
9378 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
9379 by a function call, a temporary must be created before expanding the
9380 Constructor_Call itself, to prevent out-of-order elaboration in the
9381 back-end when stack checking is enabled..
9383 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9385 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
9386 result are the bounds of the left operand, not the right.

9512 This is needed as it is necessary to have access to both versions in the
9513 runtime for the form parameter encoding support.
9514 This set of patch add support for the encoding form parameter.
9515 (S2WS): Improve implementation to handle cases where the filename is not
9516 UTF-8 encoded. In this case we default to using the current code page
9519 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration

9564 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
9565 __gnat_adjust_context_for_raise.
9566 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
9567 implementation of floating point operations as native x86 targets.
9568 So the FPU should be initialized in the same way using finit. Fix
9569 floating point operations accuracy issues.
9570 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
9571 member in struct sigaction, so as to avoid warning for incompatible

9590 Modify the loop that collects type references, to include interface
9591 types that the type implements. List each of these interfaces when
9592 building the entry for the type.

9638 2007-04-06 Robert Dewar <dewar@adacore.com>
9640 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
9641 it no longer destroys the contents of Name_Buffer or Name_Len and
9642 non-standard and invalid names are handled better.
9643 (Get_Decoded_Name_String): Improve performance by using
9644 Name_Has_No_Encodings flag in the name table.
9645 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
9646 Used for debugging printouts.

9657 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
9658 illegal in Ada 95, in cases where it is legal. Change the warnings to
9659 errors in other cases. Don't give the error unless the "not null"
9660 parses properly. Correct the source position at which the error occurs.
9661 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
9662 P_Null_Exclusion, to suppress "not null" warnings.

9792 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
9793 full word is no longer compared twice.
9795 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9797 * sem_ch10.adb (Install_Limited_Context_Clauses.
9798 Expand_Limited_With_Clause): Use a new copy of selector name in the
9799 call to Make_With_Clause. This fixes the tree structure for ASIS
9800 purposes. Nothing is changed in the compiler behaviour.
9801 (Process_Body_Clauses): Handle properly use clauses whose prefix is
9803 (Install_Limited_With_Clauses): Do not install non-limited view when it
9804 is still incomplete.
9806 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9807 Gary Dismukes <dismukes@adacore.com>
9809 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
9810 when capturing size information, instead of base type, which for a
9811 formal array type will be the unconstrained type.
9812 (Analyze_Formal_Object_Declaration): Add check for illegal default
9813 expressions for a formal in object of a limited type.
9814 (Instantiate_Object): Ditto.
9815 (Check_Formal_Package_Instance): Skip entities that are formal objects,
9816 because they were defaulted in the formal package and no check applies
9818 (Check_Formal_Package_Instance): Extend conformance check to other
9819 discrete types beyond Integer.
9820 (Process_Default): Copy directly the unmatched formal. A generic copy
9821 has already been performed in Analyze_Formal_Package.
9822 (Analyze_Associations): If a formal subprogram has no match, check for
9823 partial parametrization before looking for a default, to prevent
9825 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
9826 not set the instantiation environment before analyzing the actuals.
9827 Fixes regression on 8515-003 with implementation of AI-133.
9828 Set_Instance_Env checks whether the generic unit is a predefined
9829 unit, in which case the instance must be analyzed with the latest Ada
9830 mode. This setting must take place after analysis of the actuals,
9831 because the actuals must be analyzed and frozen in the Ada mode extant
9832 outside of the current instantiation.
9833 (Save_Env, Restore_Env): Preserve and restore the configuration
9834 parameters so that predefined units can be compiled in the proper Ada
9836 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
9837 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
9838 and Is_Abstract_Type.
9839 (Analyze_Formal_Package): For better error recovery, Add exception
9840 handler to catch Instantion_Error, which can be raised in
9841 Analyze_Associations

9844 Bob Duff <duff@adacore.com>
9845 Gary Dismukes <dismukes@adacore.com>
9847 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
9848 prefix type is a discriminated subtype of the type of the formal.
9849 (Analyze_Allocator): Collect all coextensions regardless of the context.
9850 Whether they can be allocated statically is determined in exp_ch4.
9851 (Analyze_Selected_Component): If the prefix is a limited view and the
9852 non-limited view is available, use the non-limited one.
9853 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
9854 therefore illegal), suggest a qualified expression rather than a type
9855 conversion, because a type conversion would be illegal in this context.
9856 (Anayze_Allocator): Trace recursively all nested allocators so that all
9857 coextensions are on the corresponding list for the root. Do no mark
9858 coextensions if the root allocator is within a declaration for a stack-
9859 allocated object, because the access discriminants will be allocated on
9861 (Analyze_Call): Remove restriction on calls to limited functions for the
9862 cases of generic actuals for formal objects, defaults for formal objects
9863 and defaults for record components.
9864 (Analyze_Allocator): Before analysis, chain coextensions on the proper
9865 element list. Their expansion is delayed until the enclosing allocator
9866 is processed and its finalization list constructed.
9867 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
9868 for an operation with the given name among the primitive operations of
9869 the corresponding record type.
9870 (Analyze_Selected_Component): If the prefix is a task type that
9871 implements an interface, and there is no entry with the given name,
9872 check whether there is another primitive operation (e.g. a function)
9874 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
9875 properly the indexing of a function call written in prefix form, where
9876 the function returns an array type, and all parameters of the function
9877 except the first have defaults.
9878 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
9879 the original operands, rather than relocating them, for efficiency and
9880 to work properly when an operand is overloaded.
9881 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
9882 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
9883 (Analyze_Selected_Component): If the prefix is a private extension, only
9884 scan the visible components, not those of the full view.
9885 (Try_Primitive_Operation): If the operation is a procedure, collect all
9886 possible interpretations, as for a function, because in the presence of
9887 classwide parameters several primitive operations of the type can match
9888 the given arguments.
9890 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9891 Robert Dewar <dewar@adacore.com>
9893 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

9898 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9899 Thomas Quinot <quinot@adacore.com>
9901 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
9902 out of Analyze_Package_Declaration, because processing must be applied
9903 to package bodies as well, for deferred constants completed by pragmas.
9904 (Analyze_Package_Declaration): When the package declaration being
9905 analyzed does not require an explicit body, call Check_Completion.
9906 (May_Need_Implicit_Body): An implicit body is required when a package
9907 spec contains the declaration of a remote access-to-classwide type.
9908 (Analyze_Package_Body): If the package contains RACWs, append the
9909 pending subprogram bodies generated by exp_dist at the end of the body.
9910 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
9911 Is_Abstract_Subprogram and Is_Abstract_Type.
9912 (Preserve_Full_Attributes): The full entity list is not an attribute
9913 that must be preserved from full to partial view.
9915 * sem_dist.adb (Add_RAS_Dereference_TSS):
9916 Change primitive name to _Call so it cannot clash with any legal
9917 identifier, and be special-cased in Check_Completion.
9918 Mark the full view of the designated type for the RACW associated with
9919 a RAS as Comes_From_Source to get proper view switching when installing
9920 private declarations.
9921 Provite a placeholder nested package body along with the nested spec
9922 to have a place for Append_RACW_Bodies to generate the calling stubs
9923 and stream attributes.
9925 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9926 Robert Dewar <dewar@adacore.com>
9928 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
9929 that is a limited view, check the non-limited view if available.
9930 (Undefined): Refine error message for missing with of Text_IO
9931 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
9932 to distinguish real missing with cases.
9933 Fix format of all missing with messages
9934 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
9935 renaming as body when renamed entity is abstract.
9937 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9938 Javier Miranda <miranda@adacore.com>
9940 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
9941 predicate recursive, to handle complex expressions on literals whose
9942 spurious ambiguity comes from the abstract interpretation of some
9944 (Interface_Present_In_Ancestor): Add support to concurrent record
9946 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
9947 Is_Abstract_Subprogram and Is_Abstract_Type.
9949 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9950 Javier Miranda <miranda@adacore.com>
9952 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
9953 dereference of a local object R created as a reference to another
9954 object O, use the access level of O.
9955 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
9956 rather than local Same_Formal_Type, to check whether protected operation
9957 overrides an inherited one.
9958 (Same_Formal_Type): New predicate, used when matching signatures of
9959 overriding synchronized operations, to handle the case when a formal
9960 has a type that is a generic actual.
9961 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
9962 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
9963 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
9964 syntactic ambiguities involving indexing of function calls that return
9966 (Abstract_Interface_List): New subprogram that returns the list of
9967 abstract interfaces associated with a concurrent type or a
9968 concurrent record type.
9969 (Interface_Present_In_Parent): New subprogram used to check if a
9970 given type or some of its parents implement a given interface.
9971 (Collect_Abstract_Interfaces): Add support for concurrent types
9972 with interface types.
9973 (Has_Abstract_Interfaces): Add support for concurrent types with
9975 (Is_Parent): New subprogram that determines whether E1 is a parent
9976 of E2. For a concurrent type its parent is the first element of its
9977 list of interface types; for other types this function provides the
9978 same result than Is_Ancestor.
9979 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
9980 (Collect_Synchronized_Interfaces): Removed because the subprogram
9981 Collect_Abstract_Interfaces provides this functionality.
9982 (Collect_Abstract_Interfaces): Minor update to give support to
9983 concurrent types and thus avoid undesired code duplication.
9984 (Get_Subprogram_Entity): Handle entry calls.
9985 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
9987 (Enter_Name): Do not give -gnatwh hiding warning for record component
9988 entities, they never result in hiding.

9998 (Local_Raise_Statements): New field in N_Exception_Handler_Node
9999 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

10003 can be an E_Return_Statement.
10004 (Is_Coextension): New flag for allocators.

10013 before propagating exception.
10015 2007-04-06 Olivier Hainque <hainque@adacore.com>
10017 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
10018 an address always within the call instruction from a return address.
10020 2007-04-06 Olivier Hainque <hainque@adacore.com>
10021 Eric Botcazou <botcazou@adacore.com>
10023 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
10024 expression with a COMPOUND_EXPR including the call instead of emitting

10318 anonymous access types.
10319 (Valid_Conversion): For a conversion to a numeric type occurring in an

10604 alignment of a field in a variant record might not be accurate. Add a
10605 safety test to make sure no alignment is set to a smaller value than
10606 the alignment of the field type.

10910 assignments where the target subtype is unconstrained and the target
10911 object is a parameter or dereference (other aliased cases are known
10912 to be unconstrained).

11027 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
11028 are build-in-place function calls.
11029 (Replace_Self_Reference): New subsidiary of
11030 Make_OK_Assignment_Statement, to replace an access attribute that is a
11031 self-reference into an access to the appropriate component of the
11032 target object. Generalizes previous mechanism to handle self-references
11033 nested at any level.
11034 (Is_Self_Referential_Init): Remove, not needed.
11035 (Is_Self_Referential_Init): New predicate to simplify handling of self
11036 referential components in record aggregates.

11038 check for presence of entity before checking for self-reference.
11039 (Has_Default_Init_Comps): Return True if a component association is a
11040 self-reference to the enclosing type, which can only come from a
11041 default initialization.
11042 (Make_OK_Assignment_Statement): If the expression is of the form
11043 Typ'Acc, where Acc is an access attribute, the expression comes from a
11044 default initialized self-referential component.
11045 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
11046 that has been derived from several abstract interfaces we must also

11055 (Expand_Access_To_Protected_Op): If the context indicates that an access
11056 to a local operation may be transfered outside of the object, create an
11057 access to the wrapper operation that must be used in an external call.
11058 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
11059 target, pass the Valid attribute applied to a floating-point prefix on
11060 to the back end without expansion.
11061 (Storage_Size): Use the new run-time function Storage_Size to retrieve
11062 the allocated storage when it is specified by a per-object expression.
11063 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
11064 Nothing to do here, the attribute has been rewritten during semantic

11073 into a fat pointer.
11074 (Is_Constrained_Aliased_View): New predicate to help determine whether a
11075 subcomponent's enclosing variable is aliased with a constrained subtype.
11076 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
11077 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
11078 an aliased prefix must be known to be constrained in order to use True
11079 for the attribute value, and now it's possible for some aliased views
11080 to be unconstrained.
11082 2006-10-31 Robert Dewar <dewar@adacore.com>
11084 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue

11093 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
11094 register in the final list objects containing class-wide interfaces;
11095 otherwise we incorrectly register the tag of the interface in the final
11097 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
11098 generate the wrapper if the parent primitive is abstract. This is
11099 required to report the correct error message.
11100 (Expand_N_Subtype_Indication): Do validity checks on range
11101 (Clean_Task_Names): If an initialization procedure includes a call to
11102 initialize a task (sub)component, indicate that the procedure will use
11103 the secondary stack.
11104 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
11105 compatibility for interfacing with CPP by default.
11106 (Expand_N_Object_Declaration): Only build an Adjust call when the
11107 object's type is a nonlimited controlled type.
11108 * exp_ch3.adb: Add with and use of Exp_Ch6.
11109 (Expand_N_Object_Declaration): Check for object initialization that is a
11110 call to build-in-place function and apply Make_Build_In_Place_Call_In_
11111 Object_Declaration to the call.
11112 (Freeze_Type): When the designated type of an RACW was not frozen at the
11113 point where the RACW was declared, validate the primitive operations
11114 with respect to E.2.2(14) when it finally is frozen.
11115 (Build_Initialization_Call,Expand_Record_Controller): Rename
11116 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
11117 return-by-reference has no meaning in Ada 2005.
11118 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
11119 to register tag of the immediate ancestor interfaces in the
11120 run-time structure.
11121 (Init_Secondary_Tags): Moved to the specification to allow the
11122 initialization of extension aggregates with abstract interfaces.
11123 (Build_Master_Renaming): Make public, for use by function declarations
11124 whose return type is an anonymous access type.
11125 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
11126 Insert_List_Before_And_Analyze after the generation of the specs
11127 associated with null procedures.
11128 (Expand_Tagged_Root): Update documentation in its specification.
11129 (Init_Secondary_Tags): Update documentation.
11130 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
11131 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
11132 then generate code to inherit the contents of the dispatch table
11133 directly from the ancestor.
11134 (Expand_Record_Controller): Insert controller component after tags of
11135 implemented interfaces.
11136 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
11137 create null procedure overridings when null procedures are inherited

11140 declarations for overriding null primitives inherited from interfaces.
11141 (Is_Null_Interface_Procedure): New function in
11142 Make_Null_Procedure_Specs.
11143 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
11144 immediate ancestor of a tagged type is an abstract interface type we
11145 must generate the specification of the predefined primitives associated
11146 with controlled types (because the dispatch table of the ancestor is
11147 null and hence these entries cannot be inherited). This is required to
11148 elaborate well the dispatch table.

11158 (Expand_N_In): Do validity checks on range
11159 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
11160 (Expand_N_Allocator): For "new T", if the object is constrained by
11161 discriminant defaults, allocate the right amount of memory, rather than
11162 the maximum for type T.
11163 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
11164 when the allocator is initialized by a build-in-place call, since the
11165 allocator is already rewritten as a reference to the function result,
11166 and this prevents an unwanted duplication of the function call.
11167 Add with and use of Exp_Ch6.
11168 (Expand_Allocator_Expresssion): Check for an allocator whose expression
11169 is a call to build-in-place function and apply
11170 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
11171 untagged designated types).
11172 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
11173 optimization if source or target is biased.
11174 (Expand_N_Allocator): Add comments for case of an allocator within a
11175 function that returns an anonymous access type designating tasks.
11176 (Expand_N_Allocator): apply discriminant checks for access
11177 discriminants of anonymous access types (AI-402, AI-416)

11186 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
11187 (Expand_N_Assignment_Statement): Call
11188 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
11189 build-in-place function call. Currently, this can happen only for
11190 assignments that come from aggregates.
11191 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11192 in order to alleviate the upward compatibility introduced by AI-318.
11193 (Expand_N_Extended_Return_Statement): Add support for handling the
11194 return object as a build-in-place result.
11195 (Expand_Non_Function_Return): Implement simple return statements nested
11196 within an extended return.
11197 (Enable_New_Return_Processing): Turn on the new processing of return
11199 (Expand_Non_Function_Return): For a return within an extended return,
11200 don't raise Program_Error, because Sem_Ch6 now gives a warning.
11201 (Expand_N_Extended_Return_Statement): Implement AI-318
11202 (Expand_Simple_Function_Return): Ditto.
11203 (Expand_N_If_Statement): Handle new -gnatwt warning

11205 (Expand_N_Assignment): Handle assignment to the Priority attribute of
11206 a protected object.
11207 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
11208 validity checking of assignments to elementary record components.
11209 (Expand_N_Return_Statement): return Class Wide types on the secondary
11210 stack independantly of their controlled status since with HIE runtimes,
11211 class wide types are not potentially controlled anymore.
11213 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
11216 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
11217 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
11218 it expects a block, procedure, or task. The return statement will get
11219 turned into a block, and Expand_Cleanup_Actions will happen then.

11223 Bob Duff <duff@adacore.com>
11224 Gary Dismukes <dismukes@adacore.com>
11226 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
11228 (Expand_Inlined_Call): Tagged types are by-reference types, and
11229 therefore should be replaced by a renaming declaration in the expanded
11230 body, as is done for limited types.
11231 (Expand_Call): If this is a call to a function with dispatching access
11232 result, propagate tag from context.
11233 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
11235 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
11236 build-in-place when the right-hand side of an assignment is a
11237 build-in-place function call.
11238 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
11239 of the explicit dereference of the allocator to the result subtype of
11240 the build-in-place function. This is needed to satisfy type checking
11241 in cases where the caller's return object is created by an allocator for
11242 a class-wide access type and the type named in the allocator is a
11244 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
11245 conversion of the reference to the declared object to the result subtype
11246 of the build-in-place function. This is needed to satisfy type checking
11247 in cases where the declared object has a class-wide type. Also, in the
11248 class-wide case, change the type of the object entity to the specific
11249 result subtype of the function, to avoid passing a class-wide object
11250 without explicit initialization to the back end.
11251 (Register_Interface_DT_Entry): Moved outside the body of
11252 Freeze_Subprogram because this routine is now public; it is called from
11253 Check_Dispatching_Overriding to handle late overriding of abstract
11254 interface primitives.
11255 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
11256 adding an implicit access actual on a call to a build-in-place function.

11258 build-in-place function and apply
11259 Make_Build_In_Place_Call_In_Anonymous_Context to the call.

11261 entity is a function whose calls should be handled as build-in-place.
11262 (Is_Build_In_Place_Function_Call): New function to determine whether an
11263 expression is a function call that should handled as build-in-place.
11264 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
11265 calls to build-in-place functions as the initialization of an allocator.
11266 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
11267 handling calls to build-in-place functions in contexts that do not
11268 involve init of a separate object (for example, actuals of subprogram
11270 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
11271 handling calls to build-in-place functions as the initialization of an
11272 object declaration.

11274 instantiation of Traverse_Body to avoid unreferenced warning.
11275 (Check_Overriding_Inherited_Interfaces): Removed.

11277 (Register_Predefined_DT_Entry): Code cleanup.
11278 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
11279 inlined statements if within a transient scope.
11280 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
11281 formal parameters with occurrences of actuals in inlined body, establish
11282 visibility on the proper view of the actual's subtype for the body's
11284 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
11285 compatibility mode and we have an imported CPP subprogram because
11286 for now we assume that imported CPP primitives correspond with
11287 objects whose constructor is in the CPP side (and therefore we
11288 don't need to generate code to register them in the dispatch table).
11289 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
11290 aligned selected component.
11291 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
11292 the actual of an in-mode parameter is a type conversion.
11293 (Expand_Actuals): If the call does not come from source and the actual
11294 is potentially misaligned, let gigi handle it rather than rejecting the
11295 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
11296 Class Wide types as returning by reference independantly of their
11297 controlled status since with HIE runtimes class wide types are not
11298 potentially controlled anymore.

11313 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
11314 initialization of Homonym_Len.
11315 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
11316 names from fully qualified name. Fixes problem of duplicate
11317 external names differing only in the presence of such a block name.

11320 Pablo Oliveira <oliveira@adacore.com>
11322 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
11323 subprogram Ids, even if they are not yet assigned.
11324 (Build_Subprogram_Id): It is now this function that will take care of
11325 calling Assign_Subprogram_Ids if necessary.
11326 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
11327 should be done only once they are assigned.

11331 type for an RACW type.

11335 special reordering of controlling formals.

11343 fixed-point operations in an integer context, i.e. as operands of a
11344 conversion to an integer type, indicate that result must be rounded.
11346 2006-10-31 Robert Dewar <dewar@adacore.com>
11348 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
11349 cases, pass the encoding method, since it is now required by the run
11352 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
11353 assumption that Str'First = 1.
11354 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
11355 it on to the Value_Wide_Wide_Character call.
11356 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
11357 properly handles a string of the form quote-encoded_wide_char-quote.
11359 * s-wchcnv.adb: Minor reformatting
11361 2006-10-31 Javier Miranda <miranda@adacore.com>
11363 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
11364 run-time membership test to ensure that the constructed object
11365 implements the target abstract interface.
11367 2006-10-31 Robert Dewar <dewar@adacore.com>
11369 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
11370 Machine_Attribute pragma internally to implement the user pragma.
11371 Add processing for pragma Interface so that it is now completely
11372 equivalent to pragma Import.
11374 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
11375 so that it can be applied to all entities, including record components
11376 and enumeration literals.
11377 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
11378 priority ranges are correct, verify compatibility against task
11379 dispatching and locking policies, and if everything is correct an entry
11380 is added to the table containing priority specific dispatching entries
11381 for this compilation unit.
11382 (Delay_Config_Pragma_Analyze): Delay processing
11383 Priority_Specific_Dispatching pragmas because when processing the
11384 pragma we need to access run-time data, such as the range of
11385 System.Any_Priority.
11386 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
11387 Allow pragma Unreferenced as a context item
11388 Add pragma Preelaborable_Initialization
11389 (Analyze_Pragma, case Interface): Interface is extended so that it is
11390 now syntactically and semantically equivalent to Import.
11391 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
11392 insertion characters.
11393 Add handling for Pragma_Wide_Character_Encoding
11394 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
11395 never supercedes a real restriction, and that a real restriction
11396 always supercedes a warning.
11397 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
11400 2006-10-31 Bob Duff <duff@adacore.com>
11401 Ed Schonberg <schonberg@adacore.com>
11402 Robert Dewar <dewar@adacore.com>
11404 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
11405 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
11406 Is_Inherently_Limited_Type, because return-by-reference has no meaning
11408 (Find_Node_To_Be_Wrapped): Use new method of determining the result
11409 type of the function containing a return statement, because the
11410 Return_Type field was removed. We now use the Return_Applies_To field.
11412 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
11413 (Build_Task_Image_Decl): If procedure is not called from an
11414 initialization procedure, indicate that function that builds task name
11415 uses the sec. stack. Otherwise the enclosing initialization procedure
11416 will carry the indication.
11417 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
11418 N_Object_Declaration instead.
11419 (Kill_Dead_Code): New interface to implement -gnatwt warning for
11420 conditional dead code killed, and change implementation accordingly.
11421 (Insert_Actions): Add N_Return_Object_Declaration case.
11422 Correct comment to mention N_Extension_Aggregate node.
11423 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
11424 attempts to save information for global variables which cannot be
11426 (Get_Current_Value_Condition): Handle conditions the other way round
11427 (constant on left). Also handle right operand of AND and AND THEN
11428 (Set_Current_Value_Condition): Corresponding changes
11429 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
11430 (Get_Current_Value_Condition): Handle simple boolean operands
11431 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
11432 (Get_Current_Value_Condition): If the variable reference is within an
11433 if-statement, does not appear in the list of then_statments, and does
11434 not come from source, treat it as being at unknown location.
11435 (Get_Current_Value_Condition): Enhance to allow while statements to be
11436 processed as well as if statements.
11437 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
11439 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
11440 of loop. This is safe now that we fixed Kill_Current_Values.
11441 (OK_To_Do_Constant_Replacement): Check whether current scope is
11442 Standard, before examining outer scopes.
11444 2006-10-31 Vincent Celier <celier@adacore.com>
11446 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
11447 When True, apply VMS treatment to children of packages A, G, I and S.
11450 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
11452 2006-10-31 Robert Dewar <dewar@adacore.com>
11453 Ed Schonberg <schonberg@adacore.com>
11455 * freeze.adb: Add handling of Last_Assignment field
11456 (Warn_Overlay): Supply missing continuation marks in error msgs
11457 (Freeze_Entity): Add check for Preelaborable_Initialization
11459 * g-comlin.adb: Add Warnings (Off) to prevent new warning
11461 * g-expect.adb: Add Warnings (Off) to prevent new warning
11463 * lib-xref.adb: Add handling of Last_Assignment field
11464 (Generate_Reference): Centralize handling of pragma Obsolescent here
11465 (Generate_Reference): Accept an implicit reference generated for a
11466 default in an instance.
11467 (Generate_Reference): Accept a reference for a node that is not in the
11468 main unit, if it is the generic body corresponding to an subprogram
11471 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
11473 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
11475 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
11477 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
11478 use clauses, to avoid messages on packages used to qualify, and also
11479 to avoid messages from obsolescent units.
11480 (Warn_On_Useless_Assignments): Don't generate messages for imported
11481 and exported variables.
11482 (Warn_On_Useless_Assignments): New procedure
11483 (Output_Obsolescent_Entity_Warnings): New procedure
11484 (Check_Code_Statement): New procedure
11486 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
11487 Change name Is_Ada_2005 to Is_Ada_2005_Only
11488 (Last_Assignment): New field for useless assignment warning
11490 2006-10-31 Olivier Hainque <hainque@adacore.com>
11492 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
11493 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
11495 2006-10-31 Bob Duff <duff@adacore.com>
11496 Robert Dewar <dewar@adacore.com>
11497 Ed Schonberg <schonberg@adacore.com>
11499 * g-awk.adb (Default_Session, Current_Session): Compile this file in
11500 Ada 95 mode, because it violates the new rules for AI-318.
11502 * g-awk.ads: Use overloaded subprograms in every case where we used to
11503 have a default of Current_Session. This makes the code closer to be
11504 correct for both Ada 95 and 2005.
11506 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
11507 code, relying on the fact that the compiler generates a warning
11508 instead of an error in -gnatg mode.
11510 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
11511 E_Return_Statement entity kind.
11512 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
11514 * par.adb (P_Interface_Type_Definition): Addition of one formal to
11515 report an error if the reserved word abstract has been previously found.
11516 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
11518 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
11519 parenthesized range attribute usage
11520 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
11522 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
11523 in the syntax for extended_return_statement. This is not in the latest
11524 RM, but the ARG is expected to issue an AI allowing this.
11525 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
11526 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
11527 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
11528 P_Return_Statement): Parse the new syntax for extended_return_statement.
11530 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
11531 Output_End_Missing): Add error-recovery code for the new
11532 extended_return_statement syntax; that is, the new E_Return entry on
11535 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
11536 limited to nonlimited, because otherwise we violate the new Ada 2005
11537 rules about returning limited types in function Create_AST_Handler in
11540 * sem.adb (Analyze): Add cases for new node kinds
11541 N_Extended_Return_Statement and N_Return_Object_Declaration.
11543 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
11544 type is in the same category as type of context before applying check,
11545 to prevent anomalies in instantiations.
11546 (Resolve_Aggregate): Remove test for limited components in aggregates.
11547 It's unnecessary in Ada 95, because if it has limited components, then
11548 it must be limited. It's wrong in Ada 2005, because limited aggregates
11550 (Resolve_Record_Aggregate): Move check for limited types later, because
11551 OK_For_Limited_Init requires its argument to have been resolved.
11552 (Get_Value): When copying the component default expression for a
11553 defaulted association in an aggregate, use the sloc of the aggregate
11554 and not that of the original expression, to prevent spurious
11555 elaboration errors, when the expression includes function calls.
11556 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
11557 were missing. We also didn't handle qualified expressions. Now also
11558 allow function calls. Use new common routine OK_For_Limited_Init.
11559 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
11560 with space can upper case letter).
11562 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
11563 Has_Static_Discriminants flag
11564 (Record_Type_Declaration): Diagnose an attempt to declare an interface
11565 type with discriminants.
11566 (Process_Range_Expr_In_Decl): Do validity checks on range
11567 (Build_Discriminant_Constraints): Use updated form of
11568 Denotes_Discriminant.
11569 (Process_Subtype): If the subtype is a private subtype whose full view
11570 is a concurrent subtype, introduce an itype reference to prevent scope
11572 (Build_Derived_Record_Type, Collect_Interface_Primitives,
11573 Record_Type_Declaration): The functionality of the subprograms
11574 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
11575 is now performed by a single routine.
11576 (Build_Derived_Record_Type): If the type definition includes an explicit
11577 indication of limitedness, then the type must be marked as limited here
11578 to ensure that any access discriminants will not be treated as having
11579 a local anonymous access type.
11580 (Check_Abstract_Overriding): Issue a detailed error message when an
11581 abstract subprogram was not overridden due to incorrect mode of its
11583 (Analyze_Private_Extension_Declaration): Add support for the analysis of
11584 synchronized private extension declarations. Verify that the ancestor is
11585 a limited or synchronized interface or in the generic case, the ancestor
11586 is a tagged limited type or synchronized interface and all progenitors
11587 are either limited or synchronized interfaces.
11588 Derived_Type_Declaration): Check for presence of private extension when
11589 dealing with synchronized formal derived types.
11590 Process_Full_View): Enchance the check done on the usage of "limited" by
11591 testing whether the private view is synchronized.
11592 Verify that a synchronized private view is completed by a protected or
11594 (OK_For_Limited_Init_In_05): New function.
11595 (Analyze_Object_Declaration): Move check for limited types later,
11596 because OK_For_Limited_Init requires its argument to have been resolved.
11597 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11598 in order to alleviate the upward compatibility introduced by AI-318.
11599 (Constrain_Corresponding_Record): If the constraint is for a component
11600 subtype, mark the itype as frozen, to avoid out-of-scope references to
11601 discriminants in the back-end.
11602 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
11603 this subprogram against wrong sources.
11604 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
11605 discriminant of limited type completed with a protected type, when the
11606 discriminant is used to constrain a private component of the type, and
11607 expansion is disabled.
11608 (Find_Type_Of_Object): Do not treat a return subtype that is an
11609 anonymous subtype as a local_anonymous_type, because its accessibility
11610 level is the return type of the enclosing function.
11611 (Check_Initialization): In -gnatg mode, turn the error "cannot
11612 initialize entities of limited type" into a warning.
11613 (OK_For_Limited_Init): Return true for generated nodes, since it
11614 sometimes violates the legality rules.
11615 (Make_Incomplete_Declaration): If the type for which an incomplete
11616 declaration is created happens to be the currently visible entity,
11617 preserve the homonym chain when removing it from visibility.
11618 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
11619 inherited subprograms.
11620 (Access_Definition): If this is an access to function that is the return
11621 type of an access_to_function definition, context is a type declaration
11622 and the scope of the anonymous type is the current one.
11623 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
11624 incomplete subtype to the set of private dependents of the original
11626 (Constrain_Discriminated_Type): Emit an error message whenever an
11627 incomplete subtype is being constrained.
11628 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
11629 corresponding subtype of the full view of the original incomplete type.
11630 (Check_Incomplete): Properly detect invalid usage of incomplete types
11633 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
11635 * g-catiio.ads, g-catiio.adb (Value): New function.

11644 Robert Dewar <dewar@adacore.com>
11646 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
11647 handling executable extension manually and duplicating code.
11649 * make.adb: Implement new -S switch
11650 (Gnatmake): Use new function Osint.Executable_Name instead
11651 of handling executable extension manually.
11653 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
11654 is specified, the executable name ends with this suffix.
11655 Take advantage of Osint.Executable_Name instead of duplicating code.
11657 * switch-m.adb: Recognize new gnatmake -S switch
11659 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
11661 (Get_Target_Parameters): Set Executable_Extension_On_Target if
11664 * makeusg.adb: Add line for gnatmake -S switch
11666 2006-10-31 Vincent Celier <celier@adacore.com>
11668 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
11669 call it with -static-libgcc, as there are some platforms, such as
11670 Darwin, where one of these two switches is compulsory to link.
11672 2006-10-31 Vincent Celier <celier@adacore.com>
11674 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
11675 instead of ADA_PROJECT_PATH, for the project path.
11676 (Gnatls): When displaying the project path directories, use host dir
11679 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
11680 names in the project path, as absolute paths may correspond to
11681 multi-valued VMS logical names.
11683 2006-10-31 Vincent Celier <celier@adacore.com>
11685 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
11686 absolute path name.
11687 (Locate_Regular_File): Ditto
11688 (Change_Dir): Remove, no longer used
11689 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
11690 on Windows. Get it calling Get_Current_Dir.
11691 (OpenVMS): Remove imported boolean, no longer needed.
11692 (Normalize_Pathname)[VMS]: Do not resolve directory names.
11693 (Pid_To_Integer): New function to convert a Process_Id to Integer
11695 2006-10-31 Thomas Quinot <quinot@adacore.com>
11697 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
11698 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
11700 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
11703 2006-10-31 Robert Dewar <dewar@adacore.com>
11705 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
11706 initial letter o as a zero.
11708 2006-10-31 Robert Dewar <dewar@adacore.com>
11710 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
11712 2006-10-31 Robert Dewar <dewar@adacore.com>
11714 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
11716 (Layout_Variant_Record): Retrieve the discriminants from the entity
11717 rather than from the type definition, because in the case of a full
11718 type for a private type we need to take the discriminants from the
11720 (Layout_Component_List): When applying the Max operator to variants with
11721 a nonstatic size, check whether either operand is static and scale that
11722 operand from bits to storage units before applying Max.
11723 (Layout_Type): In VMS, if a C-convention access type has no explicit
11724 size clause (and does not inherit one in the case of a derived type),
11725 then the size is reset to 32 from 64.
11727 2006-10-31 Vincent Celier <celier@adacore.com>
11729 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
11730 its file has already been loaded, according to the unit being loaded,
11731 not to the current value of Multiple_Unit_Index.
11733 2006-10-31 Thomas Quinot <quinot@adacore.com>
11734 Eric Botcazou <ebotcazou@adacore.com>
11735 Arnaud Charlet <charlet@adacore.com>
11737 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
11738 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
11740 (a-except.o): Pass it to the compiler.
11741 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
11742 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
11743 a-calend-mingw.adb version.
11745 * Makefile.rtl: Added s-dsaser.
11746 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
11747 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
11748 Ada.Dispatching.Round_Robin.
11749 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
11751 * Make-lang.in: Remove all references to gt-ada-decl.h.
11752 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
11754 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
11755 Update dependencies.
11757 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
11759 2006-10-31 Vincent Celier <celier@adacore.com>
11761 * mlib-utl.adb (Initialized): Remove, no longer used
11762 (Initialize): Remove, no longer used
11763 (Ar): If Ar_Exec is null, get the location of the archive builder and,
11764 if there is one, the archive indexer. Fail if the archive builder cannot
11766 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
11769 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11771 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
11772 Process_Body_Clauses): If the context of a body includes a use clause
11773 for P.Q then a with_clause for P in the same body is not redundant,
11774 even if the spec also has a with_clause on P.
11775 Add missing continuation mark to error msg
11776 (Build_Limited_Views): A limited view of a type is tagged if its
11777 declaration includes a record extension.
11778 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
11779 node, even if the subunit has errors. This avoids malfunction by
11780 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
11781 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
11782 generation of obsolescent messages for with statements (cannot do
11783 this too early, or we cannot implement avoiding the messages in the
11784 case of obsolescent units withing obsolescent units).
11785 (Install_Siblings): If the with_clause is on a remote descendant of
11786 an ancestor of the current compilation unit, find whether there is
11787 a sibling child unit that is immediately visible.
11788 (Remove_Private_With_Clauses): New procedure, invoked after completing
11789 the analysis of the private part of a nested package, to remove from
11790 visibility the private with_clauses of the enclosing package
11792 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
11793 now centralized in Generate_Reference.
11794 (Install_Limited_Context_Clauses): Remove superfluous error
11795 message associated with unlimited view visible through use
11796 and renamings. In addition, at the point in which the error
11797 is reported, we add the backslash to the text of the error
11798 to ensure that it is reported as a single error message.
11799 Use new // insertion for some continuation messages
11800 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
11801 to create implicit with_clause for parent unit mentioned in original
11802 limited_with_clause.

11821 a formal object declaration with an access definition or a subtype mark
11822 with a null exclusion.
11823 (P_Generic_Association): Handle association with box, and others_choice
11824 with box, to support Ada 2005 partially parametrized formal packages.

11869 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
11870 dot, instead of replacing only the first '_'.

11874 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
11875 extended, the project id of the project extending it is recorded in its

11884 Robert Dewar <dewar@adacore.com>
11886 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
11887 only a restriction warning is active for the given restriction. This is
11888 desirable because we do not want to modify code in the case where only
11890 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
11891 causes overriding of real restrictions.
11892 Take advantage of new No_Restrictions constant.
11894 * raise.h: (__gnat_set_globals): Change profile.
11896 2006-10-31 Arnaud Charlet <charlet@adacore.com>
11898 * rtsfind.adb: Remove s-polint from comment as it exists no more.
11901 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.

11921 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
11922 properly an attempt to apply Unchecked_Access to a protected operation.
11923 (OK_Self_Reference): New subprogram to check the legality of an access
11924 attribute whose prefix is the type of an enclosing aggregate.
11925 Generalizes previous mechanism to handle attribute references nested
11926 arbitrarily deep within the aggregate.
11927 (Analyze_Access_Attribute): An access attribute whose prefix is a type
11928 can appear in an aggregate if this is a default-initialized aggregate
11929 for a self-referential type.
11930 (Resolve_Attribute, case Access): Ditto.

11936 Has_Specified_Stream_Attribute flag.
11937 Disallow Storage_Size and Storage_Pool for access to subprogram
11938 (Resolve_Attribute, case 'Access et al): Take into account anonymous
11939 access types of return subtypes in extended return statements. Remove
11940 accessibility checks on anonymous access types when Unchecked_Access is
11942 (Analyze_Attribute): Add support for the use of 'Class to convert
11943 a class-wide interface to a tagged type.
11944 Add support for the attribute Priority.
11945 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
11946 whether the designated type is discriminated with a constrained partial
11947 view and require static matching in that case.
11948 Add local variable Des_Btyp. The Designated_Type
11949 of an access to incomplete subtype is either its non-limited view if
11950 coming from a limited with or its etype if regular incomplete subtype.
11952 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
11953 Fix predicate to identify and allow cases of (expander-generated)
11954 references to tag of designated object of a RACW.
11955 (Validate_Static_Object_Name): In Ada 2005, a formal object is
11956 non-static, and therefore cannot appear as a primary in a preelaborable
11958 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
11959 Has_Read_Write_Attributes.
11960 (Has_Read_Write_Attributes): Reimplement in termes of
11961 Has_Stream_Attribute_Definition.
11962 (Missing_Read_Write_Attributes): When checking component types in a

11964 (remove guard checking for Is_Record_Type / Is_Access_Type).
11966 2006-10-31 Robert Dewar <dewar@adacore.com>
11968 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
11969 useless assignments here and conditionalize it on absence of exception

11972 detection code, for new handling of formal packages.
11974 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11975 Hristian Kirtchev <kirtchev@adacore.com>
11977 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
11978 that has been constant-folded, preserve information of original tree,
11980 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
11981 generated private extension declaration if the formal derived type is
11982 synchronized. Carry synchronized present over to the generated private
11984 (Validate_Derived_Type_Instance): Ensure that the actual of a
11985 synchronized formal derived type is a synchronized tagged type.
11986 (Instantiate_Formal_Package): When creating the instantiation used to
11987 validate the actual package of a formal declared without a box, check
11988 whether the formal itself depends on a prior actual.
11989 (Instantiate_Formal_Subprogram): Create new entities for the defining
11990 identifiers of the formals in the renaming declaration, for ASIS use.
11991 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
11992 a renaming declaration or a subtype declaration for an actual in an
11993 instance, capture location information of declaration in generic, for
11995 (Instantiate_Formal_Package): Add comments on needed additional tests.
11996 AI-317 (partial parametrization) is fully implemented.
11997 (Validate_Private_Type_Instance): Add check for actual which
11998 must have preelaborable initialization
11999 Use new // insertion for some continuation messages
12000 (Analyze_Formal_Object_Declaration): Change usage of Expression to
12001 Default_Expression. Add type retrieval when the declaration has an
12002 access definition. Update premature usage of incomplete type check.
12003 (Check_Access_Definition): New subsidiary routine. Check whether the
12004 current compilation version is Ada 05 and the supplied node has an
12006 (Instantiate object): Alphabetize local variables. Handle the creation
12007 of new renaming declarations with respect to the kind of definition
12008 used - either an access definition or a subtype mark. Guard against
12009 unnecessary error message in the context of anonymous access types after
12010 they have been resolved. Add check for required null exclusion in a
12011 formal object declaration.
12012 (Switch_View): A private subtype of a non-private type needs to be
12013 switched (the base type can have been switched without its private
12014 dependents because of the last branch of Check_Private_View.
12015 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
12017 (Instantiate_Type): Emit an error message whenever a class-wide type of
12018 a tagged incomplete type is used as a generic actual.
12019 (Find_Actual_Type): Extend routine to handle a component type in a child
12020 unit that is imported from a formal package in a parent.
12021 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
12022 agree on constrainedness, rather than checking against ultimate ancestor
12023 (Instantiate_Subprogram_Body): Create a cross-reference link to the
12024 generic body, for navigation purposes.
12026 2006-10-31 Robert Dewar <dewar@adacore.com>
12027 Thomas Quinot <quinot@adacore.com>
12029 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
12031 (New_Stream_Subprogram): When processing an attribute definition clause
12032 for a stream-oriented subprogram, record an entity node occurring at
12033 the point of clause to use for checking the visibility of the clause,
12034 as defined by 8.3(23) as amended by AI-195.
12035 (New_Stream_Subprogram): New procedure, factoring behaviour from both
12036 New_Stream_Function and New_Stream_Procedure.
12037 (New_Stream_Function, New_Stream_Procedure): Removed.
12038 (Analyze_Attribute_Definition_Clause, case Address): Check new
12039 Alignment_Check check

12042 Javier Miranda <miranda@adacore.com>
12043 Robert Dewar <dewar@adacore.com>
12045 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
12046 generate the same errors compiling under -gnatc.
12047 (Try_Object_Operation): If no candidate interpretation succeeds, but
12048 there is at least one primitive operation with the right name, report
12049 error in call rather than on a malformed selected component.
12050 (Analyze_Selected_Component): If the prefix is an incomplete type from
12051 a limited view, and the full view is available, use the full view to
12052 determine whether this is a prefixed call to a primitive operation.
12053 (Operator_Check): Verify that a candidate interpretation is a binary
12054 operation before checking the type of its second formal.
12055 (Analyze_Call): Add additional warnings for function call contexts not
12057 (Analyze_Allocator): Move the check for "initialization not allowed for
12058 limited types" after analyzing the expression. This is necessary,
12059 because OK_For_Limited_Init looks at the structure of the expression.
12060 Before analysis, we don't necessarily know what sort of expression it
12061 is. For example, we don't know whether F(X) is a function call or an
12062 indexed component; the former is legal in Ada 2005; the latter is not.
12063 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
12064 were missing. We also didn't handle qualified expressions. Now also
12065 allow function calls. Use new common routine OK_For_Limited_Init.
12066 (Analyze_Type_Conversion): Do not perform some legality checks in an
12067 instance, because the error message will be redundant or spurious.
12068 (Analyze_Overloaded_Selected_Component): Do not do style check when
12069 setting an entity, since we do not know it is the right entity yet.
12070 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
12071 (Analyze_Overloaded_Selected_Component): Same change
12072 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
12073 since regular incomplete subtypes are transformed into corresponding
12074 subtypes of their full views.
12075 (Complete_Object_Operation): Treat name of transformed subprogram call
12076 as coming from source, for browsing purposes.
12077 (Try_Primitive_Operation): If formal is an access parameter, compare
12078 with base type of object to determine whether it is a primitive
12080 (Operator_Check): If no interpretation of the operator matches, check
12081 whether a use clause on any candidate might make the operation legal.
12082 (Try_Class_Wide_Operation): Check whether the first parameter is an
12083 access type whose designated type is class-wide.

12090 warn on infinite loops.
12091 Add \\ to some continuation messages
12092 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
12093 (Process_Bounds): If the bounds are integer literals that result from
12094 constant-folding, and they carry a user-defined type, preserve that type
12095 rather than treating this as an integer range.
12096 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
12097 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
12098 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
12099 left hand side of assignment.
12100 (Analyze_Assignment): Add suport to manage assigments to the attribute
12101 priority of a protected object.
12102 (Check_Possible_Current_Value_Condition): Allow fully qualified names
12103 not just identifiers.
12104 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
12105 or AND THEN for possible tracking.
12106 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
12107 case of while loops so we can track values in the loop body.
12109 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12110 Hristian Kirtchev <kirtchev@adacore.com>
12111 Bob Duff <duff@adacore.com>
12113 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
12114 procedure cannot be a protected operation (it is a basic_declaration,
12115 not a subprogram_declaration).
12116 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
12117 Subp. Add logic for entry processing.
12118 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
12119 Determine whether an entry or subprogram of a protected or task type
12120 override an inherited primitive of an implemented interface.
12121 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
12122 Update the actual used in calls to Check_Overriding_Indicator.
12123 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
12124 generate the proper reference to the parent unit, for cross-reference.
12125 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
12127 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
12128 (Add_Extra_Formal): Revise procedure to allow passing in associated
12129 entity, scope, and name suffix, and handle setting of the new
12130 Extra_Formals field.
12131 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
12132 pass new parameters. Add support for adding the new extra access formal
12133 for functions whose calls are treated as build-in-place.
12134 (Analyze_A_Return_Statement): Correct casing in error message.
12135 Move Pop_Scope to after Analyze_Function_Return, because an extended
12136 return statement really is a full-fledged scope. Otherwise, visibility
12137 doesn't work right. Correct use of "\" for continuation messages.
12138 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
12139 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
12140 the node doesn't get properly marked as analyzed.
12141 (Analyze_Subprogram_Body): If subprogram is a function that returns
12142 an anonymous access type that denotes a task, build a Master Entity
12144 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
12145 proper usage of null exclusion in a result definition.
12146 (Process_Formals): Code cleanup and new error message.
12147 (Process_Formals): Detect incorrect application of null exclusion to
12149 (Conforming_Types): Handle conformance between [sub]types and itypes
12150 generated for entities that have null exclusions applied to them.
12151 (Maybe_Primitive_Operation): Add an additional type retrieval when the
12152 base type is an access subtype. This case arrises with null exclusions.
12153 (New_Overloaded_Entity): Do not remove the overriden entity from the
12154 homonym chain if it corresponds with an abstract interface primitive.
12155 (Process_Formals): Replace membership test agains Incomplete_Kind with a
12156 call to the synthesized predicate Is_Incomplete_Type.
12157 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
12159 (Analyze_Subprogram_Declaration): Check that abstract interface
12160 primitives are abstract or null.
12161 (Analyze_Subprogram_Specification): Remove previous check for abstract
12162 interfaces because it was not complete.
12163 (Has_Interface_Formals): Removed.

12166 Javier Miranda <miranda@adacore.com>
12168 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
12169 of Analyze_Package_Body, to create Itype references for anonymous
12170 access types created in the package declaration, whose designated types
12171 may have only a limited view.
12172 (Analyze_Package_Specification): For the private part of a nested
12173 package, install private_with_clauses of enclosing compilation unit if
12174 we are in its visible part.
12175 (Declare_Inherited_Private_Subprograms): Complete barrier
12176 to ensure that the primitive operation has an alias to some parent
12177 primitive. This is now required because, after the changes done for the
12178 implementation of abstract interfaces, the contents of the list of
12179 primitives has entities whose alias attribute references entities of
12180 such list of primitives.
12181 (Analyze_Package_Specification): Simplify code that handles parent units
12182 of instances and formal packages.
12183 (Uninstall_Declarations): Check the convention consistency among
12184 primitive overriding operations of a tagged record type.

12195 (Analyze_Generic_Renaming): Same fix
12196 (Use_One_Package): Do not take into account the internal entities of
12197 abstract interfaces during the analysis of entities that are marked
12198 as potentially use-visible.
12199 (Find_Type): Handle the case of an attribute reference for
12200 implementation defined attribute Stub_Type (simply let the analysis of
12201 the attribute reference rewrite it).
12202 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
12203 type that appears in a Use_Type clause.
12204 (Analyze_Object_Renaming): Add support for renaming of the Priority
12206 (Find_Type): In Ada 2005, a task type can be used within its own body,
12207 when it appears in an access definition.
12208 (Analyze_Object_Renaming): Remove warning on null_exclusion.
12209 (Analyze_Object_Renaming): Introduce checks for required null exclusion
12210 in a formal object declaration or in a subtype declaration.
12211 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
12212 (Check_Null_Exclusion): New local routine to
12213 Analyze_Subprogram_Renaming. Check whether the formals and return
12214 profile of a renamed subprogram have required null exclusions when
12215 their counterparts of the renaming already impose them.
12216 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
12217 Determine whether an entity is inside a generic scope.
12218 (In_Open_Scope): First pass of documentation update.
12219 (Find_Expanded_Name): Add support for shadow entities associated with
12220 limited withed packages. This is required to handle nested packages.
12221 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
12222 that makes a renaming of a limited withed package illegal.

12229 (Analyze_Task_Definition): Ditto.
12230 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
12231 (Check_Overriding_Indicator): To find overridden interface operation,
12232 examine only homonyms that have an explicit subprogram declaration, not
12233 inherited operations created by an unrelated type derivation.
12234 (Check_Overriding_Indicator): When checking for the presence of "null"
12235 in a procedure, ensure that the queried node is a procedure

12238 type when the formal is an access to variable.
12239 (Analyze_Protected_Type): Add check for Preelaborable_Initialization

12575 object, to provide mutual exclusion to the queue of pending events
12576 and the type Timing_Event is no longer a protected type.

13082 we must pass the work to the expander to generate the required code to
13083 evaluate the conversion at run-time.
13084 (Resolve_Equality_Op): Do not apply previous

13700 implied by '?' in error messages.
13702 * gnat1drv.adb: (Bad_Body): Remove '!' in warning message.
13703 (Gnat1drv): Use a goto to end of main subprogram instead of
13704 Exit_Program (E_Success) so that finalization can occur normally.
13706 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

13722 Thomas Quinot <quinot@adacore.com>
13724 * checks.adb (Build_Discriminant_Checks): If the expression being
13725 checks is an aggregate retrieve the values of its discriminants to
13726 generate the check, rather than creating a temporary and a reference
13728 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
13729 (Install_Null_Excluding_Check): Ditto
13730 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

13743 error message with the full switch.
13744 Eliminate numeric switches for binder/gnatmake
13746 * switch.ads, switch.adb (Bad_Switch): New procedure
13748 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
13749 Remove 0-9 as debug flag character possibilities
13750 -d is now controlling the primary stack size when its value is a
13751 positive. Also add checks against invalid values, and support for kb,
13752 mb. Ditto for -D switch.
13754 2006-02-13 Robert Dewar <dewar@adacore.com>
13755 Serguei Rybin <rybin@adacore.com>
13757 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
13758 save/restore routines.
13759 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13760 were not always properly handled previously.
13761 Since we are changing the tree format anyway, also get rid of the
13762 junk obsolete Immediate_Errors flag.
13763 (Tree_Read): Change the way of reading Tree_Version_String - now we
13764 read the version string from the tree even if its length is not the
13765 same as the length of the version string computed from Gnatvsn.
13766 (Search_Directory_Present): New Boolean flag for the compiler.
13767 Define Tree_Version_String as a dynamic string.
13768 (Default_Stack_Size): new variable, used to handle switch -d.
13771 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
13772 only for main unit.
13773 Add pragma Ada_2005 (synonym for Ada_05)
13774 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13775 were not always properly handled previously.
13777 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
13778 explicit Ada_95 to Ada_2005.

13781 Robert Dewar <dewar@adacore.com>
13782 Ed Schonberg <schonberg@adacore.com>
13784 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
13785 against errors in the source program: a private types for which the
13786 corresponding full type declaration is missing and pragma CPP_Virtual
13788 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
13789 (Is_Known_Null): New flag
13790 (Has_Pragma_Pure): New flag
13791 (No_Return): Present in all entities, set only for procedures
13792 (Is_Limited_Type): A type whose ancestor is an interface is limited if
13793 explicitly declared limited.
13794 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
13795 entities. Only used for component marked Is_Tag. If present it stores
13796 the Offset_To_Top function used to provide this value in tagged types
13797 whose ancestor has discriminants.
13799 * exp_ch2.adb: Update status of new Is_Known_Null flag
13801 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
13803 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
13804 the categorization sense if Is_Pure was set by pragma Pure_Function.
13806 2006-02-13 Quentin Ochem <ochem@adacore.com>
13807 Olivier Hainque <hainque@adacore.com>
13809 * bindusg.adb: Updated documentation for -d and -D switches.
13811 * raise.h (__gnat_set_globals): added new parameter for
13812 Default_Stack_Size.
13814 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
13815 (__gnat_handle_vms_condition): Adjust context before raise.
13816 (__gnat_install_handler): Restore the global vector setup for GCC
13817 versions before 3.4, as the frame based circtuitry is not available
13819 (__gnat_set_globals): added a parameter default_stack_size
13820 (__gl_default_stack_size): new variable.
13822 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13824 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
13825 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
13826 does not exist in the Ada RM.
13827 (Compatible_Int_Bounds): Determine whether two integer range bounds
13828 are of equal length and have the same start and end values.
13829 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
13830 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
13831 aggregate when it is part of an object declaration.
13832 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
13833 constrains discriminants of its parent, add explicitly the discriminant
13834 constraints of the ancestor by retrieving them from the
13835 stored_constraint of the parent.
13837 2006-02-13 Robert Dewar <dewar@adacore.com>
13839 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
13840 attribute Mechanism_Code is applied to renamed subprogram, modify
13841 prefix to point to base subprogram.
13842 Max/Min attributes now violate Restriction No_Implicit_Conditionals
13844 * sinfo.ads: Document that Mechanism_Code cannot be applied to
13845 renamed subprograms so that the front-end must replace the prefix
13848 2006-02-13 Javier Miranda <miranda@adacore.com>
13849 Gary Dismukes <dismukes@adacore.com>
13851 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
13852 availability of RE_Interface_Tag.
13853 (Build_Initialization_Call): Fix wrong access to the discriminant value.
13854 (Freeze_Record_Type): Do not generate the tables associated with
13855 timed and conditional dispatching calls through synchronized
13856 interfaces if compiling under No_Dispatching_Calls restriction.
13857 When compiling for Ada 2005, for a nonabstract
13858 type with a null extension, call Make_Controlling_Function_Wrappers
13859 and insert the wrapper function declarations and bodies (the latter
13860 being appended as freeze actions).
13861 (Predefined_Primitive_Bodies): Do not generate the bodies of the
13862 predefined primitives associated with timed and conditional
13863 dispatching calls through synchronized interfaces if we are
13864 compiling under No_Dispatching_Calls.
13865 (Build_Init_Procedure): Use RTE_Available to check if a run-time
13866 service is available before generating a call.
13867 (Make_Controlling_Function_Wrappers): New procedure.
13868 (Expand_N_Full_Type_Declaration): Create a class-wide master for
13869 access-to-limited-interfaces because they can be used to reference
13870 tasks that implement such limited interface.
13871 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
13872 procedure spec and body of the Offset_To_Top function that is generated
13873 when the parent of a type with discriminants has secondary dispatch
13875 (Init_Secondary_Tags): Handle the case in which the parent of the type
13876 containing secondary dispatch tables has discriminants to generate the
13877 correct arguments to call Set_Offset_To_Top.
13878 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
13880 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
13881 Add Wide_[Wide_]Expanded_Name.
13882 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
13883 the same functionality of Get_Prim_Op_Address but applied to predefined
13884 primitive operations because the pointers to the predefined primitives
13885 are now saved in a separate table.
13886 (Parent_Size): Modified to get access to the separate table of primitive
13887 operations or the parent type.
13888 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
13889 functionality of Set_Prim_Op_Address but applied to predefined primitive
13891 (Set_Signature): New subprogram used to store the signature of a DT.
13892 (Displace): If the Offset_To_Top value is not static then call the
13893 function generated by the expander to get such value; otherwise use
13894 the value stored in the table of interfaces.
13895 (Offset_To_Top): The type of the actual has been changed to Address to
13896 give the correct support to tagged types with discriminants. In this
13897 case this value is stored just immediately after the tag field.
13898 (Set_Offset_To_Top): Two new formals have been added to indicate if the
13899 offset_to_top value is static and hence pass this value to the run-time
13900 to store it in the table of interfaces, or else if this value is dynamic
13901 and then pass to the run-time the address of a function that is
13902 generated by the expander to provide this value for each object of the
13905 * rtsfind.ads (Default_Prin_Op_Count): Removed.
13906 (Default_Prim_Op_Count): New entity
13907 (Get_Predefined_Prim_Op_Address): New entity
13908 (Set_Predefined_Prim_Op_Address): New entity
13909 (RE_Set_Signature): New entity

13912 Ed Schonberg <schonberg@adacore.com>
13914 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
13915 Make_Adjust_Call done for a newly-allocated object.
13917 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
13918 in a subprogram are wrapped in a cleanup block, indicate that the
13919 subprogram contains an inner block with an exception handler.
13920 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
13921 Adjust call is for a newly-allocated object. In that case we must not
13922 assume that the finalization list chain pointers are correct (since they
13923 come from a bit-for-bit copy of the original object's pointers) so if
13924 the attach level would otherwise be zero (no change), we set it to 4
13925 instead to cause the pointers to be reset to null.
13927 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
13928 reset chain pointers to null.
13930 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13932 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
13933 string, and the context requires a loop for the assignment (e.g.
13934 because the left-hand side is packed), generate a unique name for the
13935 temporary that holds the string, to prevent spurious name clashes.
13937 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13938 Javier Miranda <miranda@adacore.com>
13939 Robert Dewar <dewar@adacore.com>
13940 Gary Dismukes <dismukes@adacore.com>
13942 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
13943 return unconstrained arrays.
13945 (Expand_Call): An indirect call through an access parameter of a
13946 protected operation is not a protected call.
13947 Add circuit to raise CE in Ada 2005 mode following call
13948 to Raise_Exception.
13949 (Register_DT_Entry): Do nothing if
13950 the run-time does not give support to abstract interfaces.
13951 (Freeze_Subprogram): In case of dispatching operations, do not generate
13952 code to register the operation in the dispatch table if the source
13953 is compiled with No_Dispatching_Calls.
13954 (Register_Predefined_DT_Entry): Generate code that calls the new
13955 run-time subprogram Set_Predefined_Prim_Op_Address instead of
13956 Set_Prim_Op_Address.
13958 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
13959 on array assignments if the right-hand side is a function call that has
13960 been inlined. Check is performed on the assignment in the block.
13961 (Process_Bounds): If bounds and range are overloaded, apply preference
13962 rule for root operations to disambiguate, and diagnose true ambiguity.
13963 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
13964 a tag-indeterminate right-hand side even when Expander_Active is True.
13965 Needed to ensure that dispatching calls to T'Input are allowed and
13966 get the tag of the target class-wide object.
13968 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
13969 an inherited primitive operation that already overrides several
13970 abstract interface primitives. For transitivity, the new entity must
13971 also override all the abstract interface primitives covered by the
13972 inherited overriden primitive.
13973 Emit warning if new entity differs from homograph in same scope only in
13974 that one has an access parameter and the other one has a parameter of
13975 a general access type with the same designated type, at the same
13976 position in the signature.
13977 (Make_Inequality_Operator): Use source locations of parameters and
13978 subtype marks from corresponding equality operator when creating the
13979 tree structure for the implicit declaration of "/=". This does not
13980 change anything in behaviour except that the decoration of the
13981 components of the subtree created for "/=" allows ASIS to get the
13982 string images of the corresponding identifiers.
13983 (Analyze_Return_Statement): Remove '!' in warning message.
13984 (Check_Statement_Sequence): Likewise.
13985 (Analyze_Subprogram_Body): For an access parameter whose designated type
13986 is an incomplete type imported through a limited_with clause, use the
13987 type of the corresponding formal in the body.
13988 (Check_Returns): Implicit return in No_Return procedure now raises
13989 Program_Error with a compile time warning, instead of beging illegal.
13990 (Has_Single_Return): Function returning unconstrained type cannot be
13991 inlined if expression in unique return statement is not an identifier.
13992 (Build_Body_To_Inline): It is possible to inline a function call that
13993 returns an unconstrained type if all return statements in the function
13994 return the same local variable. Subsidiary procedure Has_Single_Return
13995 verifies that the body conforms to this restriction.
13997 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
13998 same type, and one of them is of an anonymous access type, convert
13999 the other operand to it, so that this is a valid binary operation for
14001 (Resolve_Type_Conversion): Handle subtypes of protected types and
14002 task types when accessing to the corresponding record type.
14003 (Resolve_Allocator): Add '\' in 2-line warning message.
14004 Remove '!' in warning message.
14005 (Resolve_Call): Add '\' in 2-line warning message.
14006 (Valid_Conversion): Likewise.
14007 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
14008 resulting type may be an access type with an implicit dereference.
14009 Obtain the proper component from the designated type.
14010 (Make_Call_Into_Operator): Handle properly a call to predefined equality
14011 given by an expanded name with prefix Standard, when the operands are
14012 of an anonymous access type.
14013 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
14014 Explicit_Dereference and Resolve_Selected_Component, to verify that the
14015 prefix of the expression is not of an incomplete type. Allows full
14016 diagnoses of all semantic errors.
14017 (Resolve_Actuals): If the actual is an allocator whose directly
14018 designated type is a class-wide interface we build an anonymous
14019 access type to use it as the type of the allocator. Later, when
14020 the subprogram call is expanded, if the interface has a secondary
14021 dispatch table the expander will add a type conversion to force
14022 the displacement of the pointer.
14023 (Resolve_Call): If a function that returns an unconstrained type is
14024 marked Inlined_Always and inlined, the call will be inlined and does
14025 not require the creation of a transient scope.
14026 (Check_Direct_Boolean_Op): Removed
14027 (Resolve_Comparison_Op): Remove call to above
14028 (Resolve_Equality_Op): Remove call to above
14029 (Resolve_Logical_Op): Inline above, since this is only call.
14030 (Valid_Conversion): Handle properly conversions between arrays of
14031 convertible anonymous access types.
14034 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
14035 the literal in an unchecked conversion, because GCC 4.x needs a static
14036 value for a string bound.
14038 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14039 Hristian Kirtchev <kirtchev@adacore.com>
14041 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
14042 components of the corresponding record, take into account component
14043 definitions that are access definitions.
14044 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
14045 procedure is not considered a dispatching call and will be expanded
14048 2006-02-13 Javier Miranda <miranda@adacore.com>
14050 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
14051 controlling argument of the dispatching call is an abstract interface
14052 class-wide type then we use it directly.
14053 Check No_Dispatching_Calls restriction.
14054 (Default_Prim_Op_Position): Remove the code that looks for the last
14055 entity in the list of aliased subprograms. This code was wrong in
14057 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
14058 when the source is compiled with the No_Dispatching_Calls restriction.
14059 (Init_Predefined_Interface_Primitives): No need to inherit primitives
14060 if we are compiling with restriction No_Dispatching_Calls.
14061 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
14062 subprograms if we are compiling under No_Dispatching_Calls restriction.
14063 (Make_DT): Generate a dispatch table with a single dummy entry if
14064 we are compiling with the No_Dispatching_Calls restriction. In
14065 addition, in this case we don't generate code that calls to the
14066 following run-time subprograms: Set_Type_Kind, Inherit_DT.
14067 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
14068 of this subprogram if compiling with the No_Dispatching_Calls
14070 (Expand_Type_Conversion): Instead of using the actual parameter,
14071 the argument passed as parameter to the conversion function was
14072 erroneously referenced by the expander.
14073 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
14074 Set_Predefined_Primitive_Op_Address and Set_Signature.
14075 (Expand_Dispatching_Call): Generate call to
14076 Get_Predefined_Prim_Op_Address for predefined primitives.
14077 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
14078 predefined primitives.
14079 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
14080 primitives we reserve one dummy entry to ensure that the tag does not
14081 point to some memory that is associated with some other object. In
14082 addition, remove all the old code that generated the assignments
14083 associated with the signature of the dispatch table and replace them
14084 by a call to the new subprogram Set_Signature.
14085 (Set_All_DT_Position): Change the algorithm because now we have a
14086 separate dispatch table associated with predefined primitive operations.
14087 (Expand_Interface_Conversion): In case of non-static offset_to_top
14088 add explicit dereference to get access to the object after the call
14089 to displace the pointer to the object.
14090 (Expand_Interface_Thunk): Modify the generation of the actual used
14091 in the calls to the run-time function Offset_To_Top to fulfil its
14093 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
14095 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14097 * exp_dist.adb (Copy_Specification): For access parameters, copy
14098 Null_Exclusion flag, which will have been set for stream subprograms
14101 2006-02-13 Pascal Obry <obry@adacore.com>
14103 * expect.c (__gnat_expect_portable_execvp): New implementation. The
14104 previous implementation was using the C runtime spawnve routine but
14105 the corresponding wait was using directly the Win32 API. This was
14106 causing some times a lock when waiting for an event using
14107 WaitForSingleObject in __gnat_waitpid. This new implementation uses
14108 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
14109 API fixes this problem.
14111 2006-02-13 Robert Dewar <dewar@adacore.com>
14113 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

14120 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
14121 array reference that is an explicit dereference, mark the converted
14122 (packed) array reference as analyzed to prevent a forthcoming
14123 reanalysis from resetting its type to the original (non-packed) array

14127 Javier Miranda <miranda@adacore.com>
14128 Eric Botcazou <ebotcazou@adacore.com>
14130 * exp_util.ads, exp_util.adb (Find_Prim_Op,
14131 Is_Predefined_Primitive_Operation): When
14132 searching for the predefined equality operator, verify that operands
14133 have the same type.
14134 (Is_Predefined_Dispatching_Operation): Remove the code that looks
14135 for the last entity in the list of aliased subprograms. This code
14136 was wrong in case of renamings.
14137 (Set_Renamed_Subprogram): New procedure
14138 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
14139 Exp_Type constant computed when entering this subprogram.
14140 (Known_Null): New function
14141 (OK_To_Do_Constant_Replacement): New function
14142 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
14143 (Side_Effect_Free): An attribute reference 'Input is not free of
14144 side effect, unlike other attributes that are functions. (from code
14146 (Remove_Side_Effects): Expressions that involve packed arrays or records
14147 are copied at the point of reference, and therefore must be marked as
14148 renamings of objects.
14149 (Is_Predefined_Dispatching_Operation): Return false if the operation is
14150 not a dispatching operation.

14159 task types when accessing to the corresponding record type.
14160 Remove '!' in warning message.
14162 2006-02-13 Olivier Hainque <hainque@adacore.com>
14164 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
14165 to avoid useless and space inefficient overalignments on targets where
14166 Max_Alignment is larger than 16.
14168 2006-02-13 Pascal Obry <obry@adacore.com>
14170 * g-catiio.adb (Sec_Number): New type used to compute the number of
14171 seconds since 1-1-1970.
14172 (Image) [Natural]: The parameter was an Integer, as we can't deal with
14173 negative numbers (years, months...) it is better to have a Natural here.
14175 (Image) [Number]: Change parameter from Long_Integer to Number.
14176 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
14177 overflow for dates past year 2038.
14179 2006-02-13 Matthew Heaney <heaney@adacore.com>
14181 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
14184 2006-02-13 Arnaud Charlet <charlet@adacore.com>
14186 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
14188 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that

14193 * gnatcmd.adb (Rules_Switches): New table
14194 (Add_To_Rules_Switches): New procedure
14195 (GNATCmd): For command CHECK, put all options following "-rules" in the
14196 Rules_Switches table. Append these -rules switches after the -cargs
14199 2006-02-13 Robert Dewar <dewar@adacore.com>
14201 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
14202 These two cases were generating incorrect output, and if this unit
14203 was built with checks on, generated a discriminant mismatch constraint
14206 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14207 Robert Dewar <dewar@adacore.com>
14209 * lib-xref.adb (Get_Type_Reference): For a private type whose full
14210 view is an array type, indicate the component type as well, for
14211 navigation purposes.
14212 (Generate_Reference): Don't consider array ref on LHS to be a case
14213 of violating pragma Unreferenced.
14214 Do not give Ada 2005 warning except on real reference.
14216 2006-02-13 Vincent Celier <celier@adacore.com>
14218 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
14219 main source, add switch -mdebug-main=_ada_ so that the executable can
14220 be debugged by the standard VMS debugger.
14221 (Gnatmake): Set No_Main_Subprogram to True when there is no main
14222 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
14223 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
14224 of the last source, as the binding and linking phases are never
14226 Set all executable obsolete when rebuilding a library.
14228 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
14231 2006-02-13 Javier Miranda <miranda@adacore.com>
14234 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
14235 code to improve the error message reported when the program has
14236 declarations of abstract interface types and it is not compiled with
14237 the -gnat05 switch.
14238 (P_Access_Definition): Reorganize the code to improve the error
14239 message reported when the new Ada 2005 syntax for anonymous
14240 access types is used and the program is not compiled with the

14263 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
14264 unknown, use the location of the project to report the error.
14265 (When_No_Sources): New global variable
14266 (Report_No_Ada_Sources): New procedure
14267 (Check): New parameter When_No_Sources. Set value of global variable
14269 (Find_Sources): Call Report_No_Ada_Sources when appropriate
14270 (Get_Sources_From_File): Ditto
14271 (Warn_If_Not_Sources): Better warning messages indicating the unit name
14274 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
14275 Call Prj.Proc.Process with parameter When_No_Sources.
14277 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
14278 Call Recursive_Check with parameter When_No_Sources.
14279 (Recursive_Check): New parameter When_No_Sources. Call itself and
14280 Prj.Nmsc.Check with parameter When_No_Sources.
14281 (Process): New parameter When_No_Sources. Call Check with parameter
14283 (Copy_Package_Declarations): New procedure to copy renamed parameters
14284 and setting the location of the declared attributes to the location
14285 of the renamed package.

14291 * prj-makr.adb (Make): Preserve the comments from the original project
14293 When removing nodes (attributes Source_Dirs, Source_Files,
14294 Source_List_File and package Naming), save the comments and attach the
14295 saved comments to the newly created nodes.
14296 Do not add a with clause for the naming package if one already exists.
14298 2006-02-13 Javier Miranda <miranda@adacore.com>

14304 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
14305 aliased entities to look for the overriden abstract interface
14307 (Is_Interface_Subprogram): Complete documentation.
14308 (Check_Dispatching_Operation): Do not generate code to register the
14309 operation in the dispatch table if the source is compiled with
14310 restriction No_Dispatching_Calls.

14312 No_Return procedure with procedure that is not No_Return
14313 (Check_Dispatching_Call): Suppress the check for an abstract operation
14314 when the original node of an actual is a tag-indeterminate attribute
14315 call, since the attribute, which must be 'Input, can never be abstract.
14316 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
14317 call to the Input attribute (even when rewritten).
14318 (Propagate_Tag): Augment comment to indicate the possibility of a call
14319 to an Input attribute.
14321 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
14322 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
14324 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
14325 No_Wide_Characters is no longer partition-wide
14326 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)

14331 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
14333 2006-02-13 Javier Miranda <miranda@adacore.com>
14335 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
14336 handles default-initialized components to keep separate the management
14337 of this feature but also avoid the unrequired resolution and
14338 expansion of components that do not have partially initialized
14340 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
14341 (Check_Bounds): Likewise.
14342 (Check_Length): Likewise.
14344 2006-02-13 Javier Miranda <miranda@adacore.com>
14345 Ed Schonberg <schonberg@adacore.com>
14347 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
14348 abstract interface type call analyze_and_resolve to expand the type
14349 conversion into the corresponding displacement of the
14350 reference to the base of the object.
14351 (Eval_Attribute, case Width): For systems where IEEE extended precision
14352 is supported, the maximum exponent occupies 4 decimal digits.
14353 (Accessibility_Message): Add '\' in 2-line warning message.
14354 (Resolve_Attribute): Likewise.
14355 (case Attribute_Access): Significantly revise checks
14356 for illegal access-to-subprogram Access attributes to properly enforce
14357 the rules of 3.10.2(32/2).
14358 Diagnose use of current instance with an illegal attribute.
14360 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
14362 (Enclosing_Generic_Unit): New function to return a node's innermost
14363 enclosing generic declaration node.
14364 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
14365 (Type_Access_Level): The accessibility level of anonymous acccess types
14366 associated with discriminants is that of the current instance of the
14367 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
14368 (Compile_Time_Constraint_Error): Handle case of conditional expression.
14369 (Kill_Current_Values_For_Entity): New function
14370 (Enter_Name): Change formal type to Entity_Id
14372 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
14373 Ed Schonberg <schonberg@adacore.com>
14374 Gary Dismukes <dismukes@adacore.com>
14376 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
14377 Analyze_Compilation_Unit.
14378 Detect and warn on redundant with clauses detected in a package spec
14379 and/or body when -gnatwr is used.
14380 (Analyze_Context): Analyze config pragmas before other items
14381 (Install_Context_Items): Don't analyze config pragmas here
14382 (Install_Limited_Withed_Unit): Set limited entity of package in
14383 with_clause so that cross-reference information or warning messages on
14384 unused packages can be properly generated
14385 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
14386 has Error_Posted set. Prevent infinite loops in illegal programs.
14387 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
14388 to the point of the error test requiring the current unit to be private.
14389 This ensures that private with clauses are not exempted from the basic
14390 checking for being a descendant of the same library unit parent as a
14391 withed private descendant unit.
14392 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
14393 handle private with clauses properly, as well as to account for cases
14394 where the withed unit is a public descendant of a private ancestor
14395 (in which case the current unit must be a descendant of the private
14396 ancestor's parent). The spec comments were updated accordingly. Also,
14397 the old error message in this subprogram was replaced with error
14398 messages that mirror the errors tested and reported by
14399 Check_Private_Child_Unit.
14400 Parameter and variable names improved for readability.
14401 (Install_Limited_Context_Clauses): Remove test for a withed unit being
14402 private as the precondition for calling
14403 Check_Private_Limited_Withed_Unit since that subprogram has been
14404 revised to test public units as well as private units.

14409 Javier Miranda <miranda@adacore.com>
14411 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
14412 that Scope_Stack.First = 1.
14413 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
14414 were not always properly handled previously.
14415 (Formal_Entity): Complete rewrite, to handle properly some complex case
14416 with multiple levels of parametrization by formal packages.
14417 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
14418 to the corresponding derived type declaration for proper semantics.
14420 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
14421 (Check_Component): Enforce restriction on components of
14422 unchecked_unions: a component in a variant cannot contain tasks or
14424 (Unchecked_Union): Allow nested variants and multiple discriminants, to
14426 Add pragma Ada_2005 (synonym for Ada_05)
14427 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
14428 were not always properly handled previously.
14429 Document that pragma Propagate_Exceptions has no effect
14430 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
14431 (Set_Convention_From_Pragma): Check that if a convention is
14432 specified for a dispatching operation, then it must be
14433 consistent with the existing convention for the operation.
14434 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
14435 longer required to specify an vtable-ptr component in the record. For
14436 compatibility reasons we leave the support for the previous definition.
14437 (Analyze_Pragma, case No_Return): Allow multiple arguments
14439 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
14440 non-overrideen inherited operation with a controlling result as
14441 illegal only its implicit declaration comes from the derived type
14442 declaration of its result's type.
14443 (Check_Possible_Deferred_Completion): Relocate the object definition
14444 node of the subtype indication of a deferred constant completion rather
14445 than directly analyzing it. The analysis of the generated subtype will
14446 correctly decorate the GNAT tree.
14447 (Record_Type_Declaration): Check whether this is a declaration for a
14448 limited derived record before analyzing components.
14449 (Analyze_Component_Declaration): Diagnose record types not explicitly
14450 declared limited when a component has a limited type.
14451 (Build_Derived_Record_Type): Code reorganization to check if some of
14452 the inherited subprograms of a tagged type cover interface primitives.
14453 This check was missing in case of a full-type associated with a private
14455 (Constant_Redeclaration): Check that the subtypes of the partial and the
14456 full view of a constrained deferred constant statically match.
14457 (Mentions_T): A reference to the current type in an anonymous access
14458 component declaration must be an entity name.
14459 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
14460 class_wide type to refer to full type, not to the incomplete one.
14461 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
14462 available. Required to give support to the certified run-time.
14463 (Analyze_Component_Declaration): In case of anonymous access components
14464 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
14465 (Process_Discriminants): For an access discriminant, use the
14466 discriminant specification as the associated_node_for_itype, to
14467 simplify accessibility checks.
14469 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14470 Javier Miranda <miranda@adacore.com>
14472 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
14473 abstract interpretations on an operator, remove interpretations that
14474 yield Address or a type derived from it, if one of the operands is an
14476 (Try_Object_Operation.Try_Primitive_Operation,
14477 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
14478 location when creating the new reference to a primitive or class-wide
14479 operation as a part of rewriting a subprogram call.
14480 (Try_Primitive_Operations): If context requires a function, collect all
14481 interpretations after the first match, because there may be primitive
14482 operations of the same type with the same profile and different return
14483 types. From code reading.
14484 (Try_Primitive_Operation): Use the node kind to choose the proper
14485 operation when a function and a procedure have the same parameter
14487 (Complete_Object_Operation): If formal is an access parameter and prefix
14488 is an object, rewrite as an Access reference, to match signature of
14489 primitive operation.
14490 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
14491 by an expanded name with prefix Standard, when the operands are of an
14492 anonymous access type.
14493 (Remove_Abstract_Operations): If the operation is abstract because it is
14494 inherited by a user-defined type derived from Address, remove it as
14495 well from the set of candidate interpretations of an overloaded node.
14496 (Analyze_Membership_Op): Membership test not applicable to cpp-class
14499 2006-02-13 Bob Duff <duff@adacore.com>
14501 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
14502 redundant use clauses.
14503 In particular, if the scope of two use clauses overlaps, but one is not
14504 entirely included in the other, we should not warn. This can happen
14505 with nested packages.
14506 (Analyze_Subprogram_Renaming): Protect the compiler against previously
14507 reported errors. The bug was reported when the compiler was built
14508 with assertions enabled.
14509 (Find_Type): If the node is a 'Class reference and the prefix is a
14510 synchronized type without a corresponding record, return the type
14513 2006-02-13 Javier Miranda <miranda@adacore.com>
14515 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
14516 if this is the full-declaration associated with a private declaration
14517 that implement interfaces, then the private type declaration must be
14519 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
14520 as aliased. The use of the 'access attribute is not available for such
14521 object (for this purpose the object should be explicitly marked as
14522 aliased, but being an anonymous type this is not possible).
14524 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14525 Robert Dewar <dewar@adacore.com>
14527 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
14528 compilation unit is an elaboration scope.
14529 (Add_Task_Proc): Add '\' in 2-line warning message.
14530 (Activate_All_Desirable): Deal with case of unit with'ed by parent
14532 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14533 Javier Miranda <miranda@adacore.com>
14535 * sem_type.adb (Write_Overloads): Improve display of candidate
14537 (Add_One_Interp): Do not add to the list of interpretations aliased
14538 entities corresponding with an abstract interface type that is an
14539 immediate ancestor of a tagged type; otherwise we have a dummy
14540 conflict between this entity and the aliased entity.
14541 (Disambiguate): The predefined equality on universal_access is not
14542 usable if there is a user-defined equality with the proper signature,
14543 declared in the same declarative part as the designated type.
14544 (Find_Unique_Type): The universal_access equality operator defined under
14545 AI-230 does not cover pool specific access types.
14546 (Covers): If one of the types is a generic actual subtype, check whether
14547 it matches the partial view of the other type.
14549 2006-02-13 Thomas Quinot <quinot@adacore.com>
14551 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
14552 line. This is necessary to allow In_Extended_Main_Unit to provide
14553 correct results for itypes while writing out expanded source.
14554 (Close_File): No need to update the source_index_table here since it's
14555 now done for each line.
14557 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14558 Robert Dewar <dewar@adacore.com>
14560 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
14561 preserve the source unit where the itype is declared, and prevent a
14563 (Note_Implicit_Run_Time_Call): New procedure
14564 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
14567 * sprint.ads: Document use of $ for implicit run time routine call
14569 2006-02-13 Quentin Ochem <ochem@adacore.com>
14571 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
14574 2006-02-13 Bob Duff <duff@adacore.com>
14576 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
14577 Scan_Unsigned, so we do not scan leading blanks and sign twice.
14578 Integer'Value("- 5") and Integer'Value("-+5") now correctly
14579 raise Constraint_Error.
14581 * s-vallli.adb (Scan_Long_Long_Integer): Call
14582 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
14583 do not scan leading blanks and sign twice.
14584 Integer'Value("- 5") and Integer'Value("-+5") now correctly
14585 raise Constraint_Error.
14587 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
14588 Scan_Long_Long_Unsigned): Split out most of the processing from
14589 Scan_Long_Long_Unsigned out into
14590 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
14591 This prevents scanning leading blanks and sign twice.
14592 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
14595 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
14596 out most of the processing from Scan_Unsigned out into
14597 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
14598 This prevents scanning leading blanks and sign twice.
14600 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
14601 use with Modular'Value attribute.
14602 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

14621 * gnat_rm.texi, gnat_ugn.texi: Remove limitations with sparc m64
14623 Document that gnatbind -M option is for cross environments only.
14624 Added description of using gnatmem to trace gnat rtl allocs and deallocs
14625 Add note on use of $ to label implicit run time calls

14800 * a-taster.ads, a-taster.adb: New files.
14802 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
14803 link to the version that does nothing. This way the task termination
14804 routine is not executed twice for the environment task when finishing
14805 because of an unhandled exception.
14807 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
14808 handler because of an unhandled exception.
14810 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

14816 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
14817 non-tasking version of the soft link for task termination. We do
14818 nothing since if we are using the non-tasking version it
14819 means that the task termination functionality is not used.
14820 (Null_Finalize_Global_List): Add this null version for the procedure
14821 in charge of finalizing the global list for controlled objects.
14822 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
14823 instead for handling run-time termination in a more flexible way.
14824 (Adafinal_NT): This new procedure will take care of finalizing the
14825 global list for controlled objects if needed, but no tasking
14828 * s-tarest.adb (Task_Lock): Do not try to lock again the
14829 Global_Task_Lock if we already own it. Otherwise, we get blocked in
14830 some run-time operations.
14831 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
14832 until all nested locks have been released.
14833 (Task_Wrapper): Call the fall-back task termination handler. It
14834 applies to all tasks but the environment task.
14835 (Finalize_Global_Tasks): Add the call for the task termination
14836 procedure for the environment task.
14837 (Task_Wrapper): suppress warnings around declaration of
14838 Secondary_Stack_Address.
14840 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
14841 moved to the Common_ATCB record.
14842 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
14843 Common_ATCB record.
14844 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
14845 Common_ATCB record.
14847 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
14848 Fall_Back_Handler, and Specific_Handler.
14850 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
14851 defined in Ada.Task_Termination, to avoid circular dependencies.
14852 (Termination_Handler): Redefine this type here, alredy defined in
14853 Ada.Task_Termination, for avoiding circular dependencies.
14854 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
14855 for storing task termination handlers. In addition,
14856 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
14857 Common_ATCB because it is used by both the regular and the restricted
14859 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
14860 Common_ATCB because it is used by both the regular and the restricted
14862 (Common_ATCB): Added a dynamic task analyzer field.
14864 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
14865 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
14866 (Task_Wrapper): Call the task termination handler. It applies to all
14867 tasks but the environment task.
14868 (Finalize_Global_Tasks): Call the task termination procedure for the
14869 environment task. The call to Finalize_Global_List is now performed
14870 using the soft links mechanism.
14871 (Task_Wrapper): added dynamic stack analysis.
14873 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
14874 potentially blocking operations has been moved from
14875 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
14876 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
14877 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
14878 this run-time check.
14880 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
14881 of task termination procedure.
14882 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
14883 link for the task termination procedure.

14899 (Standart_Output): new subprogram
14900 (Set_Output): new subprogram
14901 (Put): now uses the value of Current_Out to know if the output has to be
14902 send to stderr or stdout.

14924 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
14925 to the specification because the frontend generates code that uses this
14927 (Set_Interface_Table): Add missing assertion.
14928 Update documentation describing the run-time structure.
14929 (Displace): New subprogram that displaces the pointer to the object
14930 to reference one of its secondary dispatch tables.
14931 (IW_Membership): Modified to use the new table of interfaces.
14932 (Inherit_TSD): Modified to use the new table of interfaces.
14933 (Register_Interface_Tag): Use the additional formal to fill the
14934 contents of the new table of interfaces.
14935 (Set_Interface_Table): New subprogram that stores in the TSD the
14936 pointer to the table of interfaces.

14950 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
14951 in all the calls to Expand_Interface_Thunk. Instead of referencing the
14952 record component containing the tag of the secondary dispatch table we
14953 have to use the Offset_To_Top run-time function to get this information;
14954 otherwise if the pointer to the base of the object has been displace
14955 we get a wrong value if we use the 'position attribute.
14957 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
14958 all the calls to Expand_Interface_Thunk.
14959 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
14960 interfaces; hence the call to Set_Interface_Table was clearly wrong.

14962 ensure that the interfaces implemented by the ancestors are placed
14963 at the header of the generated list.
14964 (Expand_Interface_Conversion): Handle the case in which the displacement
14965 associated with the interface conversion is not statically known. In
14966 this case we generate a call to the new run-time subprogram Displace.
14967 (Make_DT): Generate and fill the new table of interfaces.
14968 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
14969 Get_Tagged_Kind and Set_Tagged_Kind.
14970 (Tagged_Kind): New function that determines the tagged kind of a type
14971 with respect to limitedness and concurrency and returns a reference to
14973 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
14974 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
14975 primary dispatch table for a type.

14977 secondary dispatch table respectively of a tagged type.
14979 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
14980 (Expand_Interface_Conversion): New subprogram to indicate if the
14981 displacement of the type conversion is statically known.

14990 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
14991 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
14992 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
14993 RE_TK_Tagged, RE_TK_Task.
14995 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
14996 Init_Secondary_Tags_Internal to allow its use with interface types and
14997 also to generate the code for the new additional actual required
14998 by Set_Offset_To_Top.
14999 (Build_Init_Statements): In case of components associated with abstract
15000 interface types there is no need to generate a call to its IP.
15001 (Freeze_Record_Type): Generate Select Specific Data tables only for
15003 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
15004 the bodies and specifications of the predefined primitive operations
15005 dealing with dispatching selects and abort, 'Callable, 'Terminated only
15006 for concurrent types.
15008 * exp_sel.ads, exp_sel.adb: New files.
15010 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
15011 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
15012 properly protected objects and attach handler in the case of the
15013 restricted profile.
15014 Move embeded package Select_Expansion_Utilities into a separate external
15016 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
15017 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
15018 (Build_K, Build_S_Assignment): New subprograms, part of the select
15019 expansion utilities.

15022 where the trigger is a dispatching procedure of a limited tagged type.
15024 2005-12-09 Olivier Hainque <hainque@adacore.com>
15026 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
15027 pointer initialization values. Make a SAVE_EXPR instead. Add comments
15028 about the use and expansion of SAVE_EXPRs in the various possible
15029 renaming handling cases.
15030 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
15031 abusing DECL_FCONTEXT.

15131 covered by the tag of the source.
15133 2005-12-09 Robert Dewar <dewar@adacore.com>
15135 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

15150 component associated with the secondary table of an abstract interface
15151 type, return the entity associated with such abstract interface type.
15152 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
15153 base type to create anonymous subtype, because entity may be a locally
15154 declared subtype or generic actual.
15155 (Find_Interface): New subprogram that given a tagged type and one of its
15156 component associated with the secondary table of an abstract interface
15157 type, return the entity associated with such abstract interface type.
15159 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
15160 conversion cannot be handled at compile time. In this case we pass this
15161 information to the expander to generate the appropriate code.

15196 copied component does not have a known static Esize, then reset
15197 the size and positional fields of the new component.
15198 (Analyze_Component_Declaration): A limited component is
15199 legal within a protected type that implements an interface.
15200 (Collect_Interfaces): Do not add to the list the interfaces that
15201 are implemented by the ancestors.
15202 (Derived_Type_Declaration): If the parent of the full-view is an
15203 interface perform a transformation of the tree to ensure that it has
15204 the same parent than the partial-view. This simplifies the job of the
15205 expander in order to generate the correct object layout, and it is
15206 needed because the list of interfaces of the full-view can be given in
15208 (Process_Full_View): The parent of the full-view does not need to be
15209 a descendant of the parent of the partial view if both parents are
15211 (Analyze_Private_Extension_Declaration): If declaration has an explicit
15212 "limited" the parent must be a limited type.
15213 (Build_Derived_Record_Type): A derived type that is explicitly limited

15225 differing interface is returned.
15226 (Process_Full_View): Improve the check for the "no hidden interface"
15227 rule as defined by AI-396.
15229 2005-12-09 Robert Dewar <dewar@adacore.com>
15231 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
15232 types, not on record subtypes.
15233 (Freeze_Entity): Code cleanup. Add barrier to the loop
15234 that generates the references for primitive operations. This allows to
15235 remove an unnecessary exception handler.
15236 Code reformatting and comment clean ups.

15241 If GNAT CHECK is called with a project file, but with no
15242 source on the command line, call gnatcheck with all the compilable
15243 sources of the project.
15244 Take into account the new command Check, for gnatcheck. Treat as for
15245 other ASIS tools: take into account project, specific package Check and

15285 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
15286 available user-specified stream attributes on limited parameters to
15287 also test the type directly rather than only its underlying type (for
15288 Ada 95) and, in the case of Ada 2005, to check that the user-specified
15289 attributes are visible at the point of the subprogram declaration.
15290 For Ada 2005, the error message is modified to indicate that the
15291 type's stream attributes must be visible (again, only for -gnat05).

15323 types use the corresponding record type. This was not needed before
15324 the implementation of Ada 2005 synchronized types because
15325 concurrent types were never tagged types in Ada 95.
15327 2005-12-09 Ed Schonberg <schonberg@adacore.com>
15329 * sem_ch9.adb (Analyze_Delay_Alternative, Analyze_Delay_Until): Use the

15451 2005-11-21 Joel Sherrill <joel.sherrill@oarcorp.com>
15453 * socket.c: Add extern int h_errno for rtems since networking header
15454 files are not available at this point in a tool bootstrap. Newlib
15455 only has basic C library header files.

15458 Roger Sayle <roger@eyesopen.com>
15461 * misc.c (internal_error_function): Don't use vsprintf to format
15462 the error message text, instead use pp_format_text and the new

15473 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
15474 a temporary if taking the address of something that is neither
15475 reference, declaration, or constant, since the gimplifier
15476 can't handle that case.
15478 2005-11-17 Laurent Guerby <laurent@guerby.net>
15481 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

15548 * gen-soccon.c: Complete value expansion should not be performed on
15549 TARGET, as it has the form of a math expression, and some components
15550 may be platform-defined macros.
15551 For VxWorks, generate the OK and ERROR values.
15552 New constants giving the sizes of the components of C struct timeval.
15554 2005-11-14 Robert Dewar <dewar@adacore.com>

15558 * types.ads: Include All_Checks in Suppress_Array
15560 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
15561 not(a=b), since we no longer do this rewriting, and hence it is not
15563 (Elaboration_Checks_Suppressed): Add special casing to
15564 deal with different cases of static and dynamic elaboration checks (all
15565 checks does not count in the first case, but does in the second).
15566 (Expr_Known_Valid): Do not assume that the result of any arbitrary
15567 function call is valid, since this is not the case.
15568 (Ensure_Valid): Do not apply validity check to a real literal
15569 in a universal or fixed context
15571 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
15572 elementary types using the operator in standard. It is cleaner not to
15573 modify the programmers intent, especially in the case of floating-point.
15574 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
15575 it did not matter because we always rewrote a/=b to not(a=b).
15576 (Expand_Allocator_Expression): For an allocator expression whose nominal
15577 subtype is an unconstrained packed type, convert the expression to its
15578 actual constrained subtype.
15579 Implement warning for <= or >= where < or > not possible
15580 Fix to Vax_Float tests (too early in many routines, causing premature
15581 Vax_Float expansions.
15583 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
15584 to be used with packages and generic packages as well as with
15586 (Suppress): Set All_Checks, but not Elaboration_Check, for case
15587 of pragma Suppress (All_Checks)
15588 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
15589 a string literal for precise control over warnings.
15590 Avoid raise of pragma in case of unrecognized pragma and just return
15593 * sem_prag.ads: Minor reformatting
15595 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
15596 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
15597 Switch. Do not handle any exception.
15598 Include -gnatwx as part of -gnatg (warn on redundant parens)
15599 Allow optional = after -gnatm
15600 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
15601 longer sets Elaboration_Checks.
15602 Code to set warning mode moved to Sem_Warn
15603 so that it can be shared by pragma processing.
15605 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
15608 * s-taprop-solaris.adb:
15609 Change some <= to =, to avoid new warning
15611 * a-exexda.adb, prj-proc.adb:
15612 Fix obvious typo (Num_Tracebacks compared <= 0 instead of < 0)
15613 Fix obvious typo (Total_Errors_Detected <= 0 should be = 0)
15615 2005-11-14 Robert Dewar <dewar@adacore.com>
15617 * exp_vfpt.adb: Handle /= case
15618 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

15625 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
15626 Increase default priority on Lynx from 15 to 17, and meet the Ada
15627 requirement that Default_Priority be ((Priority'First +

15730 we are not defining the type.
15731 <E_Record_Type>: Likewise.
15732 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
15733 to get advantage of the new maybe_stabilize_reference interface, to
15734 ensure that what we reference is indeed stabilized instead of relying
15735 on assumptions on what the stabilizer does.
15736 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
15737 type imported through a limited_with clause, use its non-limited view.
15738 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
15740 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
15741 of #if sections + explicit comparisons of convention identifiers.

15743 before early-returning for certain types when code generation is

15747 that we are not defining.
15748 (elaborate_expression_1): Do not create constants when creating
15749 variables needed by the debug info: the dwarf2 writer considers that
15750 CONST_DECLs is used only to represent enumeration constants, and emits
15752 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
15753 object with an address clause into an indirect reference, drop the

15766 subtype to build an actual type with bounds template.
15767 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
15768 is provided by the front-end, use that subtype to compute the size of
15769 the deallocated object.

15771 check for a potential violation of a No_Elaboration_Code restriction.

15777 without need to check for the success indication.

15779 pass false instead of 0 as the FORCE argument which is a bool.
15780 (Identifier_to_gnu): Remove checks ensuring that an renamed object
15781 attached to a renaming pointer has been properly stabilized, as no such
15782 object is attached otherwise.

15784 function uses the "target pointer" return mechanism.
15785 Reinstate conversion of the actual to the type of the formal
15786 parameter before any other specific treatment based on the passing

15796 * utils2.c (gnat_build_constructor): Only sort the fields for possible
15797 static output of record constructor if all the components are constant.
15798 (gnat_build_constructor): For a record type, sort the list of field
15799 initializers in increasing bit position order.
15800 Factor common code to build a storage type for an unconstrained object
15801 from a fat or thin pointer type and a constrained object type.
15802 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
15803 types variants, and process special cases of VIEW_CONVERT expressions
15804 as their NOP_EXPR counterpart to ensure we get to the
15805 CORRESPONDING_VARs associated with CONST_DECls.
15806 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
15807 on the right-hand side.

15814 extracting the object if converting to a type variant.
15815 (create_var_decl): When a variable has an initializer requiring code
15816 generation and we are at the top level, check for a potential violation
15817 of a No_Elaboration_Code restriction.
15818 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
15819 SIZE and SIZE_UNIT which we need for later back-annotations.

16003 with an actual subtype so GIGI can make a correct size computation.
16004 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
16005 'Unrestricted_Access, if the designated type is an interface we
16006 add a type conversion to force the displacement of the pointer
16007 to the secondary dispatch table.
16008 Use Universal_Real instead of Long_Long_Float when we need a high
16009 precision float type for the generated code (prevents gratuitous
16010 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
16011 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
16012 'Terminated for task interface class-wide objects. Generate a call to
16013 the predefined dispatching routine used to retrieve the _task_id from
16014 a task corresponding record.

16039 if-statement that has elsif_parts, recompute the Current_Value node
16040 for any entity whose value is known from the condition of the first
16042 (Expand_N_Return_Statement): When returning a mutable record, convert
16043 the return value into its actual subtype in order to help the backend
16044 to return the actual size instead of the maximum. This is another
16045 aftermath of not returning mutable records on the sec-stack anymore.

16064 a process handle, not need to convert.
16065 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.

16375 In addition some minor reorganization of the code has been done to
16376 leave it more clear.
16377 (Analyze_Type_Declaration): If type has previous incomplete tagged
16378 partial view, inherit properly its primitive operations.

16434 whose default is abstract because the object type itself is abstract.
16435 (Find_Type): If the type is incomplete and appears as the prefix of a
16436 'Class reference, it is tagged, and its list of primitive operations
16437 must be initialized properly.

16467 statement to inhibit warning.
16468 (Resolve_Unary_Op): Do not produce a warning when
16469 processing an expression of the form -(A mod B)

17302 SO_RCVTIMEO/SO_SNDTIMEO
17306 Move all target-specific file inclusions and macro definitions to
17307 gsocket.h, in order to ensure that any C code in socket.c will see a
17308 set of constants that is consistent with the contents of g-soccon.ads.
17310 * gsocket.h: Code imported from gen-soccon.c:
17311 Move all target-specific file inclusions and macro definitions to
17312 gsocket.h, in order to ensure that any C code in socket.c will see a set

17512 position set is provided, we compute one in order to reduce the maximum
17513 length of the keys. This computation first selects a character
17514 position between 1 and the minimum length of the keys in order to
17515 avoid reducing one of the keys to an empty string.
17516 (Initialize, Compute): When the ratio V to K is too low, the algorithm
17517 does not converge. The initialization procedure now comes with a

17675 2005-09-01 Javier Miranda <miranda@adacore.com>
17676 Ed Schonberg <schonberg@adacore.com>
17678 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
17679 become local to the whole package.
17680 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
17681 the package was already analyzed the new algorithm "replaces" the
17682 real entities by the shadow ones. This is required to ensure that
17683 the order of these entities in the homonym chains does not change;
17684 otherwise we can have undefined references at linking time because
17685 in case of conflicts the external name of the entities will have
17686 a suffix that depends on the order of the entities in the chain.
17687 (Remove_Limited_With_Clause): Complementary code that completes the
17688 new algorithm and replaces the shadow entities by the real ones.
17689 (Install_Limited_Withed_Unit): When unchaining entities before the
17690 installation of the shadow entities, only regular entities of the
17691 public part must be taken into account. This is required to
17692 keep this routine in synch with the work done by Remove_Limited_
17694 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
17695 even if unit is analyzed, because the analysis of the unit is
17696 idempotent in any case, and the limited view of the unit may have to
17697 be installed for proper visibility.
17698 (Expand_Limited_With_Clause): Even if the unit in the implicit
17699 with_clause has been analyzed already, a limited view of the package
17700 must be built for the current context, if it does not exist yet.
17702 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17703 Javier Miranda <miranda@adacore.com>
17704 Gary Dismukes <dismukes@adacore.com>
17706 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
17707 defining entity for the instance body, make a new defining identifier
17708 rather than copying the entity of the spec, to prevent accidental
17709 sharing of the entity list.
17710 (Check_Private_View): When exchanging views of private types, build the
17711 list of exchanged views as a stack, to ensure that on exit the exchanges
17712 are undone in the proper order.
17713 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
17714 Restore the compilation environment in case of instantiation_error.
17715 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
17716 for an anonymous access result.
17717 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
17718 (Formal_Entity): Handle properly the case of a formal package that
17719 denotes a generic package renaming.
17721 2005-09-01 Thomas Quinot <quinot@adacore.com>
17723 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
17724 clause if the array aggregate is surrounded by parentheses.
17726 2005-09-01 Cyrille Comar <comar@adacore.com>
17727 Gary Dismukes <dismukes@adacore.com>
17728 Ed Schonberg <schonberg@adacore.com>
17729 Javier Miranda <miranda@adacore.com>
17731 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
17733 to check if a type is Constrained in cases related to code generation
17734 (rather than semantic checking) since otherwise we do not generate
17735 similar code for mutable private types depending if their
17736 discriminants are visible or not.
17737 (Check_Abstract_Overriding): Do not complain about failure to override
17738 the primitive operations used in dispatching selects since they will
17739 always be overriden at the freeze point of the type.
17740 (Access_Definition): Separate out handling for resetting the scope
17741 of an anonymous access function result type. Retrieve the scope
17742 of the associated function rather than using Current_Scope, which
17743 does not have a consistent value (depends on whether we're in the
17744 middle of analyzing formal parameters). Add ??? comment about
17745 finding a cleaner way to handle the special cases of scope setting.
17746 (Process_Incomplete_Dependents): A protected operation is never a
17747 dispatching operation (only its wrapper may be).
17748 (Build_Derived_Record_Type): In case of tagged private types that
17749 implement interfaces add derivation of predefined primitive
17751 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
17752 by two parameters that are used in case of derivation from abstract
17753 interface types: No_Predefined_Prims is used to avoid the derivation
17754 of predefined primitives from the interface, and Predefined
17755 Prims_Only is used to complete the derivation predefined primitives
17756 in case of private tagged types implementing interfaces.
17757 Fix typo in comments
17758 (Find_Interface_In_Descendant): Protect the frontend against
17759 wrong code with large circularity chains.
17760 (Is_Private_Overriding): Add support for entities overriding interface
17761 subprograms. The test failed because Entities associated with overriden
17762 interface subprograms are always marked as hidden (and used to build
17763 the secondary dispatch table); in this case the overriden entity is
17764 available through the field abstract_interface_alias (cf. override_
17765 dispatching_operation)
17766 (Access_Definition): Set the scope of the type to Current_Scope for the
17767 case of a function with an anonymous access result type.
17768 (Access_Subprogram_Declaration): Handle creation of the type entity for
17769 an access-to-function type with an anonymous access result.
17770 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
17771 in handling for N_Access_Function_Definition.
17772 (Analyze_Subtype_Declaration): Modify the text of error message.
17773 (Derived_Type_Declaration): Modify the text of error message.
17774 (Process_Subtype): Modify the text of error message plus cleanup
17775 of one redundant error message.
17776 (Analyze_Component_Declaration): Code cleanup.
17777 (Analyze_Object_Declaration): Code cleanup.
17778 (Analyze_Subtype_Declaration): Propagate the null-exclusion
17779 attribute in case of access types. Code cleanup.
17780 (Array_Type_Declaration): Code cleanup.
17781 (Process_Discriminants): Create the new null-excluding itype
17782 if required. Code cleanup.
17783 (Process_Subtype): Create the new null-excluding itype if
17784 required. Code cleanup.
17785 (Build_Derived_Record_Type): Code cleanup to avoid calling
17786 twice the subprogram derive_subprograms in case of private
17787 types that implement interfaces. In this particular case the
17788 subprogram Complete_Subprograms_Derivation already does the
17789 job associated with the second call.
17791 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
17792 conversion to the full view when generating an operation for a
17793 discriminant whose type may currently be private.
17795 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17796 Javier Miranda <miranda@adacore.com>
17798 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
17799 V (Obj.F), the rewriting does not involve the indexed component, but
17800 only the selected component itself.
17801 Do not apply the transformation if the analyzed node is an actual of a
17802 call to another subprogram.
17803 (Complete_Object_Operation): Retain the entity of the
17804 dispatching operation in the selector of the rewritten node. The
17805 entity will be used in the expansion of dispatching selects.
17806 (Analyze_One_Call): Improve location of the error message associated
17808 (Analyze_Selected_Component): No need to resolve prefix when it is a
17809 function call, resolution is done when parent node is resolved, as
17811 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
17812 when attempting to resolve a call transformed from its object notation.
17813 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
17814 of the argument list for each interpretation of the operation.
17815 (Try_Object_Operation): The designated type of an access parameter may
17816 be an incomplete type obtained through a limited_with clause, in which
17817 case the primitive operations of the type are retrieved from its full
17819 (Analyze_Call): If this is an indirect call, and the return type of the
17820 access_to_subprogram is incomplete, use its full view if available.
17822 2005-09-01 Javier Miranda <miranda@adacore.com>
17823 Gary Dismukes <dismukes@adacore.com>
17825 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
17826 access types the null-exclusion and access-to-constant attributes must
17828 (Analyze_Return_Statement): When the result type is an anonymous access
17829 type, apply a conversion of the return expression to the access type
17830 to ensure that appropriate accessibility checks are performed.
17831 (Analyze_Return_Type): For the case of an anonymous access result type,
17832 generate the Itype and set Is_Local_Anonymous_Access on the type.
17833 Add ??? placeholder for check to disallow returning a limited object
17834 in Ada 2005 unless it's an aggregate or a result of a function call.
17835 Change calls from Subtype_Mark to Result_Definition.
17836 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
17837 Result_Definition in call to Make_Function_Specification.
17838 (Build_Body_To_Inline): Change Set_Subtype_Mark to
17839 Set_Result_Definition.
17840 (Make_Inequality_Operator): Change formal Subtype_Mark to
17841 Result_Definition in call to Make_Function_Specification.
17842 (Process_Formals): Create the new null-excluding itype if required.
17843 (New_Overloaded_Entity): For an entity overriding an interface primitive
17844 check if the entity also covers other abstract subprograms in the same
17845 scope. This is required to handle the general case, that is, overriding
17846 other interface primitives and overriding abstract subprograms inherited
17847 from some abstract ancestor type.
17848 (New_Overloaded_Entity): For an overriding entity that comes from
17849 source, note the operation that it overrides.
17850 (Check_Conformance, Type_Conformant): Addition of one new formal
17851 to skip controlling formals in the analysis. This is used to
17852 handle overloading of abstract interfaces.
17853 (Base_Types_Match): Add missing case for types imported from
17854 limited-with clauses
17855 (New_Overloaded_Entity): Add barrier to protect the use of
17856 the "alias" attribute.
17858 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17860 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
17861 verify that the procedure and the entry are mode conformant.
17862 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
17863 as a different operator, which is often a cut-and-paste error.
17865 2005-09-01 Javier Miranda <miranda@adacore.com>
17866 Ed Schonberg <schonberg@adacore.com>
17868 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
17869 used in controlling parameters exclude null because it is necessary to
17870 read the tag to dispatch, and null has no tag.
17871 (Override_Dispatching_Operation): If the previous operation is inherited
17872 from an interface, it becomes hidden and does not participate in later
17875 2005-09-01 Javier Miranda <miranda@adacore.com>
17876 Ed Schonberg <schonberg@adacore.com>
17877 Gary Dismukes <dismukes@adacore.com>
17879 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
17880 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
17881 the expander will generate the corresponding run-time check to evaluate
17883 (Resolve_Call): Check for legal type of procedure name or prefix that
17884 appears as a trigger in a triggering alternative.
17885 (Valid_Conversion): If expression is ambiguous and the context involves
17886 an extension of System, remove System.Address interpretations.
17887 (Resolve_Qualified_Expression): Reject the case of a specific-type
17888 qualification applied to a class-wide argument. Enhance comment
17889 to explain checking of Original_Node.
17890 (Resolve_Type_Conversion): The location of the error message was not
17891 general enough to handle the general case and hence it has been removed.
17892 In addition, this patch improves the text of the message.
17893 (Resolve_Type_Conversion): Add missing support for access to interface
17895 (Resolve_Type_Conversion): If the target is a class-wide interface type,
17896 do not expand if the expression is the actual in a call, because proper
17897 expansion will take place when the call itself is expanded.
17898 (Resolve_Allocator): If the context is an unchecked conversion, the
17899 allocator inherits its storage pool, if any, from the target type of
17902 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17903 Javier Miranda <miranda@adacore.com>
17905 * sem_type.adb (Add_One_Interp): If a candidate operation is an
17906 inherited interface operation that has an implementation, use the
17907 implementation to avoid spurious ambiguities.
17908 (Interface_Present_In_Ancestor): In case of concurrent types we can't
17909 use the Corresponding_Record_Typ attribute to look for the interface
17910 because it is set by the expander (and hence it is not always
17911 available). For this reason we traverse the list of interfaces
17912 (available in the parent of the concurrent type).
17913 (Interface_Present_In_Ancestor): Handle entities from the limited view
17915 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17917 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
17918 from the list of required components.
17919 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
17920 primitive procedure of a limited interface with a controlling first
17922 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
17924 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
17925 capture if it is generated in the second operand of a short-circuit
17927 Do not capture values for variables with address clauses.
17928 (Is_Object_Reference): Treat a function call as an object reference only
17929 if its type is not Standard_Void_Type.
17931 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17933 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
17934 to a variable that is statically known to be constant.
17936 2005-09-01 Geert Bosch <bosch@adacore.com>
17937 Robert Dewar <dewar@adacore.com>
17939 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.
17940 (VAXGF_Safe_First): Idem.

17946 Document that bounds of result of Base_Name match the input index
17948 Add documentation on environment variable syntax for Expand_Path
17950 * gnat_ugn.texi: Update documentation to include mention of -m switches
17951 Document new treatment of wide characters in max line length
17953 Remove -gnatL/-gnatZ switches, no longer used.
17954 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
17957 * gnat_rm.texi: Add doc for two argument form of pragma
17958 Float_Representation.
17959 Add documentation for pragma No_Strict_Aliasing
17960 Add note that explicit component clause overrides pragma Pack.
17961 Add documentation of pragma Debug_Policy

17971 2005-09-01 Arnaud Charlet <charlet@adacore.com>
17973 * Makefile.in: Adjust the libgnat target pairs for Xscale to ARM.
17974 Note that the platform-specific version of g-soccon.ads for VMS is now
17975 named g-soccon-vms.ads (it was previously g-soccon-vms.adb, although it
17976 really is a package spec).
17977 Replace s-taspri-linux.ads by s-taspri-posix.ads

18714 Arnaud Charlet <charlet@adacore.com>
18716 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
18717 longer protected objects. They have been replaced by lower-level
18718 suspension objects made up by a mutex and a condition variable (or
18719 their equivalent given a particular OS) plus some internal data to
18720 reflect the state of the suspension object.
18721 (Initialize, Finalize): Add this initialization procedure for
18722 Suspension_Object, which is a controlled type.
18723 (Finalize): Add the finalization procedure for Suspension_Object,
18724 which is a controlled type.
18726 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
18727 Ada.Synchronous_Task_Control because there is no longer a need for a
18728 VxWorks specific version of this package. Target dependencies
18729 has been moved to System.Task_Primitives.Operations.

18733 (InitializeCriticalSection, EnterCriticalSection,
18734 LeaveCriticalSection, DeleteCriticalSection): Replace the type
18735 pCriticalSection by an anonymous access type so that we avoid problems
18736 of accessibility to local objects.

18742 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
18743 set the environment task mask here.
18744 (Current_State): Add this function that returns the state of the
18746 (Set_False): Add this procedure that sets the state of the suspension
18748 (Set_True): Add this procedure that sets the state of the suspension
18749 object to True, releasing the task that was suspended, if any.
18750 (Suspend_Until_True): Add this procedure that blocks the calling task
18751 until the state of the object is True. Program_Error is raised if
18752 another task is already waiting on that suspension object.
18753 (Initialize): Add this procedure for initializing the suspension
18754 object. It initializes the mutex and the condition variable which are
18755 used for synchronization and queuing, and it sets the internal state
18757 (Finalize): Add this procedure for finalizing the suspension object,
18758 destroying the mutex and the condition variable.

18763 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
18764 which provides a low-level abstraction (using operating system
18765 primitives) for Ada.Synchronous_Task_Control.
18766 This object is made up by a mutex (for ensuring mutual exclusion), a
18767 condition variable (for queuing threads until the condition is
18768 signaled), a Boolean (State) indicating whether the object is open,
18769 and a Boolean (Waiting) reflecting whether there is a task already
18770 suspended on this object.

18786 (Server_Task): Explicitely test for Pending_Action in case
18787 System.Parameters.No_Abort is True.
18789 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
18790 is no longer done in the body of s-taprop

19182 access to subprograms must be recursive.
19183 (Is_Unchecked_Conversion): Improve the test that recognizes
19184 instantiations of Unchecked_Conversion, and allows them in bodies that
19185 are to be inlined by the front-end. When the body comes from an
19186 instantiation, a reference to Unchecked_Conversion will be an
19187 Expanded_Name, even though the body has not been analyzed yet.

19209 Prevent the special checks for conversions of access discriminants in
19210 the case where the discriminant belongs to a nonlimited type, since
19211 such discriminants have their accessibility level defined in the same
19212 way as a normal component of an anonymous access type.
19213 (Resolve_Allocator): When an allocator's designated type is a class-wide
19214 type, check that the accessibility level of type given in the
19215 allocator's expression or subtype indication is not statically deeper

19235 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
19236 check on possible violation of restriction No_Direct_Boolean_Operators

21009 uses of the Access_Disp_Table attribute to reference the first dispatch
21010 table associated with a tagged type. As
21011 part of the implementation of abstract interface types,

21013 tables (rather than a single dispatch table).
21014 Similarly, upgrade all the references to Tag_Component by the
21015 new attribute First_Tag_Component.
21016 (Find_Inherited_TSS): Moved to exp_tss.

21030 determine the amount of data to be copied.
21032 * par.adb (P_Interface_Type_Definition): New subprogram that parses the

21060 (Task_Body_Procedure): Removed.
21061 (Set_Task_Body_Procedure): Removed.
21062 These subprogram have been removed because the attribute
21063 Task_Body_Procedure has been moved to the corresponding task type
21064 or task subtype entity to leave a field free to store the list
21065 of interfaces implemented by a task (for AI-345)
21066 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
21067 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with

21130 expression to the type of the object when the object is constant.
21131 Reverse defer_debug_incomplete_list before traversing it, so that trees
21132 are processed in the order at which they were added to the list. This
21133 order is important when using the stabs debug format.
21134 If we are deferring the output of debug information, also defer this
21135 output for a function return type.
21136 When adding fields to a record, prevent emitting debug information

21177 N_Qualified_Expression.
21179 * sem_ch3.adb (Derived_Type_Declaration): New predicate
21180 Comes_From_Generic, to recognize accurately that the parent type in a
21181 derived type declaration can be traced back to a formal type, because
21182 it is one or is derived from one, or because its completion is derived
21184 (Constrain_Component_Type): If component comes from source and has no
21185 explicit constraint, no need to constrain in in a subtype of the
21187 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.

21215 Needed now that we do some processing for IN parameters as well. This
21216 may well fix some unrelated errors.

21218 that come from packed arrays).
21219 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the

21223 (Represented_As_Scalar): Fix to work properly with private types
21224 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more

21226 improving the quality of code that depends on this test.
21228 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
21229 over both visible and private declarations to remove them from tree,

21246 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
21247 that appears in the instantiation rather than the internal subtype
21248 generated in the wrapper package, to avoid anomalies in gigi when the
21249 target is derived from a private type whose full view is an access type.
21251 2005-03-15 Robert Dewar <dewar@adacore.com>
21253 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
21255 Add documentation to replace the use of this flag
21256 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
21259 2005-03-15 Thomas Quinot <quinot@adacore.com>
21261 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
21262 here from exp_attr so it can be shared between exp_attr and exp_dist.
21263 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
21264 all TSS names, not a subset thereof, and the previous name introduced
21265 an unnecessarily confusion that a distinction might exist between
21266 "OK" TSS names and some "not OK" TSS names.
21268 2005-03-15 Doug Rupp <rupp@adacore.com>
21270 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
21273 2005-03-15 Pascal Obry <obry@adacore.com>
21274 Eric Botcazou <ebotcazou@adacore.com>
21278 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
21279 when IN_RTS. This is to work around a bootstrap path problem.
21281 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
21282 table and pass it to __gnat_install_SEH_handler().
21283 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
21285 * lang.opt: Fix specification of -fRTS=.
21287 2005-03-15 Doug Rupp <rupp@adacore.com>
21288 Bernard Banner <banner@adacore.com>
21289 Vincent Celier <celier@adacore.com>
21290 Arnaud Charlet <charlet@adacore.com>
21293 This change works fine when gnatlib is built from the gcc directory,
21294 but does not work when using the libada Makefile, since GCC_FOR_TARGET
21295 is not passed to ada/Makefile.in, so more work is needed by a
21296 Makefile/configure expert.
21298 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
21299 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
21300 Setup gnatlink switch -M for x86_64 linux, as it is already setup
21302 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
21303 Run ranlib on libgccprefix.a
21304 Define PREFIX_OBJS for Darwin, to build libgccprefix.
21305 (ADA_INCLUDE_SRCS): Split Ada packages.
21307 2005-03-15 Robert Dewar <dewar@adacore.com>
21309 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
21311 * impunit.adb: Add GNAT.UTF_32
21313 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
21315 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
21316 now uses GNAT.UTF_32).
21318 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
21319 capabilities for categorizing characters using Unicode categories
21321 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21323 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
21324 instantiation that has been rewritten as a package body, retrieve spec
21325 to generate proper name for implicit_with_clause.
21326 (Install_Parents): Recognize a parent that is an instantiation but has
21327 been rewritten as a package declaration during analysis.
21329 2005-03-15 Javier Miranda <miranda@adacore.com>
21330 Ed Schonberg <schonberg@adacore.com>
21332 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
21333 parameter reported some error we immediately return. This improves the
21334 behaviour of the frontend in case of errors.
21335 (Install_Parent, Remove_Parent): Introduce new flag
21336 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
21337 ancestor of a generic child unit, when the child is being instantiated.
21338 (Inline_Instance_Body): If we are compiling the private
21339 part or the body of a child unit, restore the proper visibility of the
21340 parents after compiling the instance body.
21342 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21343 Javier Miranda <miranda@adacore.com>
21346 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
21347 of a private type, in which case it is underlying_type that denotes
21348 the proper task. Also modified to use the new entity attribute
21349 that is directly available in the task type and task subtype entities
21350 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
21351 arrays when other dimensions than the first are constrained by
21352 discriminants of an enclosing record.
21353 (Insert_Explicit_Dereference): If the prefix is an indexed component or
21354 a combination of indexed and selected components, find ultimate entity
21355 and generate the appropriate reference for it, to suppress spurious
21357 (Note_Possible_Modification): If an entity name has no entity, return.
21358 (Is_Variable): A function call never denotes a variable.
21359 (Requires_Transient_Scope): For record types, recurse only on
21360 components, not on internal subtypes that may have been generated for
21361 constrained components.
21363 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21365 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
21366 Eliminated as candidates for resolution. Both efficient, and avoids
21367 anomalies with operators declared in deleted code.
21368 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
21369 expansion is disabled (as when compiling a generic) to prevent spurious
21370 warnings on prefixes of selected components.
21372 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21374 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
21375 attached to a list before checking whether it appears in the private
21376 declarations of the current package.
21377 (Make_Inequality_Operator): Insert declaration in proper declarative
21378 list rather than just setting the Parent field, so that
21379 Is_Private_Declaration can handle it properly.
21381 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21383 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
21384 a renaming a body, check that the renamed subprogram in not intrinsic.
21385 (Find_Direct_Name): If several use_visible entities hide
21386 each other, and the context is a predefined file compiled through
21387 rtsfind, keep only the entity that comes from a predefined file.
21389 2005-03-15 Geert Bosch <bosch@adacore.com>
21391 * s-fatgen.adb (Valid): Extend special exceptions to account for long
21392 long float padding to also cover AMD64 and IA64.
21394 2005-03-15 Gary Dismukes <dismukes@adacore.com>
21396 * s-imgwch.adb: Add with and use of Interfaces.
21397 (Img_Wide_Character): Change type of Val to Unsigned_16.

21719 (Resolve_Slice): If the prefix is an access to an unconstrained array,
21720 compute the actual subtype of the designated object to impose the proper
21722 (Resolve_Selected_Component): Do not insert an access check if the
21723 prefix is an access type: such a node is expanded into an explicit
21724 dereference, on which the access check is performed anyway. Removes

21729 Add support for wide wide character type
21730 (Resolve_Allocator): Replace the error message on wrong null-exclusion
21731 value by a warning message.
21732 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
21733 as fixed-point, and one of the operands is non-static and universal, it
21734 can only be an illegal exponentiation operation, in which case there is
21735 no real value to retrieve.
21737 * exp_strm.adb: Add support for wide wide character type
21738 (Build_Elementary_Input_Call): Compute the size of the stream element by

21786 * stringt.ads, stringt.adb: Handle full UTF-32 range.
21787 Remove ["0A"] from comment, since it can look like a line terminator.
21788 Currently we don't permit this, but this is under discussion by the
21789 ARG, and it is easy enough to use a different example.
21791 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
21792 handling UTF-32 encoding for wide wide character.

21851 describing the new layout.
21852 (Dispatch_Table): The expander computes the actual array size, allocates
21853 the Dispatch_Table record accordingly, and generates code that displaces
21854 the base of the record after the Typeinfo_Ptr component. The access to
21855 these components is done by means of local functions.
21856 (Offset_To_Top): New function.
21857 (Typeinfo_Ptr): New function.
21858 (Get_TSD): Modified to access the new position of the TSD.

21872 dispatching, setting the controlling status of the formal parameters
21873 and result, and issuing an error if there is no controlling type for
21874 the formal subprogram.
21875 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
21876 which is an unclean use of that field, we set the new field

21890 subprogram only if inner one comes from source.
21891 (Analyze_Function_Call): If the call is given in object notation, the

21893 argument list. After analyzing the name, if the call has been rewritten
21894 and the result type is set, no further analysis is needed.
21895 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
21896 mark in function specification, in a context where the formals are
21897 visible and hide outer homographs.
21899 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
21900 as the tagged type for the cases of abstract formal subprograms and
21901 renamings of those. Clean up spec comments.
21902 (Check_Dispatching_Context): Add error message to indicate "abstract
21903 procedure", covering the case of a call to a formal abstract procedure
21904 that has statically tagged operands.
21905 (Check_Dispatching_Call): Check for the case of an actual given by
21906 a tag-indeterminate function call whose type is an ancestor of the
21907 containing call's associated tagged type. This situation can occur
21908 for inherited primitives with function defaults. In this case we
21909 use the tagged type's tag directly as the controlling argument for
21911 (Expand_Call): Name change on call to Expand_Dispatch_Call.
21913 * sprint.adb (Sprint_Node_Actual): Split
21914 N_Formal_Subprogram_Declaration into two alternatives for the new

22013 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
22014 component of an array of arrays in an assignment context, and the
22015 aggregate has component associations that require sliding on
22016 assignment, force reanalysis of the aggregate to generate a temporary
22017 before the assignment.
22018 (Must_Slide): Make global to the package, for use in Gen_Assign.
22020 2005-02-09 Ed Schonberg <schonberg@adacore.com>

22036 Arnaud Charlet <charlet@adacore.com>
22038 * init.c (__gnat_initialize): Add a new parameter eh which contains the
22039 address of the exception registration. The Win32 version of this
22040 routine calls __gnat_install_SEH_handler() to initialize the SEH
22041 (Structured Exception Handling) handler.
22042 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
22043 SEH (Structured Exception Handling) now.
22044 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
22045 (__gnat_initialize for ppc-vxworks): Adjust comments and the
22046 preprocessor condition protecting the call to the extra eh setup
22047 subprogram, which is only available for the ppc target.

22061 Update copyright notice.
22063 * s-tassta.adb (Task_Wrapper): Declare the exception registration

22093 2005-02-09 Vincent Celier <celier@adacore.com>
22095 * prj-makr.adb (Process_Directory): Put file name in canonical case
22096 before matching against the patterns.
22097 If gnatname has been invoked as <prefix>-gnatname
22098 then invoke the compiler as <prefix>-gcc, not just "gcc".

22102 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
22103 with expansion disabled. The actual subtype is needed among other
22104 places when the selected component appears in the context of a loop
22105 bound, and denotes a packed array.
22106 (Operator_Check): Always use the first subtype in the
22107 error message, to avoid the appearance of internal base types.
22108 (Transform_Object_Operation): Copy each actual in full
22109 to the parameter associations of the constructed call, rather than
22110 using the shallow copy mechanism of New_Copy_List. This ensures that
22111 the chaining of named associations is done properly.
22112 (Complete_Object_Operation): Rewrite node, rather than
22113 replacing it, so that we can trace back to the original selected
22116 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
22117 and calls that use object notation, if the called function is not
22118 declared in a withed unit, place the elaboration constraint on the
22119 unit in the context that makes the function accessible.
22120 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
22121 imposes an elaboration constraint between two packages.
22123 2005-02-09 Ed Schonberg <schonberg@adacore.com>
22125 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
22126 views of a private type after handling its private dependents, to

22148 Slight fix to documentation of -gnaty with no parameters
22150 * xr_tabls.ads: Add ??? comment for missing overall comment
22152 * xsinfo.adb: Make default file name be sinfo.h, since this is what
22153 we now use by default.
22155 * xsnames.adb: Adjust end of file test to look for five space followed
22156 by '#' instead of six spaces. The format of xsnames.adb was modified
22157 in the last update.
22159 * a-numeri.ads: Add reference to AI-388 for greek letter pi
22162 * clean.adb: Minor reformatting.
22164 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
22165 gnatname.adb: Minor reformatting
22166 Add 2005 to copyright output when utility is run
22168 * csets.adb: Eliminate obsolete comment
22170 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
22173 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
22175 2005-02-09 Sergey Rybin <rybin@adacore.com>
22177 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
22178 the difference between compact and incompact layout and add the record
22179 representation clause to the example illustrating different layouts.
22180 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
22181 component clauses").
22183 2005-02-09 Florian Villoing <villoing@adacore.com>
22185 * gnat_ugn.texi: Fix typos.
22186 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

22235 2005-02-09 Arnaud Charlet <charlet@adacore.com>
22237 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
22238 since this procedure is now too complex to be worth inlining.

22376 (Resolve_Access, case 'Access): Note that GNAT uses the context type to
22377 disambiguate overloaded prefixes, in accordance with AI-235. GNAT code
22378 predates, and partly motivates, the adoption of the AI.
22379 Implement new Ada 2005 attribute Mod

22427 exception Bad_R_Line, instead of calling Fatal_Error, so that, when
22428 Ignore_Errors is True, default restrictions are set and scanning of the
22429 ALI file continues with the next line. Also, when Bad_R_Line is raised
22430 and Ignore_Errors is True, skip to the end of le line.

22433 No_Dependence restrictions.
22434 (Install_Withed_Unit): Add code to implement AI-377 and diagnose
22435 illegal context clauses containing child units of instance.
22437 * sem_prag.adb: Processing and checking for new No_Dependence
22439 (Analyze_Pragma, case Psect_Object): Call Check_Arg_Is_External_Name to

22485 2005-01-03 Olivier Hainque <hainque@adacore.com>
22487 * decl.c (compatible_signatures_p): New function. The intended purpose
22488 is to check if two function signatures for a call-site and a callee are
22489 compatible enough for the call to be valid. The underlying purpose is
22490 to check if a call to a mapped builtin is using the right interface.
22491 The current code actually does not check antyhing - this a placeholder
22492 for future refinements.

22543 structure of GARLIC and PolyORB RPC receivers.
22544 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
22546 Simplify elaboration code for RCI packages.
22548 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver
22549 generation to reduce differences between the structure of GARLIC and

22621 * sem_ch4.adb (Has_Fixed_Op): New predicate in Check_Arithmetic_Pair,
22622 to determine whether one of the operands is a fixed-point type for
22623 which a user-defined multiplication or division operation might be

22655 porting guide chapter (vms version).
22656 Revised doc title (removed "for native platforms") and subtitle.
22657 Add discussion on warning flag for obsolescent features. First we
22658 note that it applies to obsolete GNAT features, which was previously
22659 omitted. Second we contrast the behavior with that of the new
22660 Ada 2005 AI-368 restriction No_Obsolescent_Features.
22661 Preliminary rewriting of GNAT & libraries chapter in order to take
22662 into account default project locations & new project manager

22894 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
22895 fields claimed addressable still have to be bitfields. Use
22896 value_factor_p instead of a raw binop construction to check for the
22897 position's alignment.

22904 Ed Schonberg <schonberg@adacore.com>
22906 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
22907 with an implicit dereference as its prefix, use
22908 Insert_Explicit_Dereference instead of merely rewriting the prefix into

22910 prefix is generated, if appropriate.
22912 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
22913 dereference is rewritten to an explicit one, generate a reference to
22914 the entity denoted by its prefix using the original prefix node, so

22916 access value, if appropriate.
22918 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
22919 emitting 'assigned but never read' warning on a variable on the basis

22933 an external name, to be handled by the back end.
22935 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
22936 subprogram which is Imported with convention Intrinsic if an
22937 External_Name argument is specified.
22938 (Process_Import_Or_Interface): Properly diagnose link name argument.
22939 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

22964 PolyORB_Support.Build_Stub_Type): New subrograms containing the
22965 PCS-specific part of Add_Stub_Type.

22995 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
22996 and the Has_Pragma_Unreferenced flag for each formal before analyzing
22997 the body, to ensure that warnings are properly emitted for each accept
22998 statement of a given task entry.

23030 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
23031 used to record an implicit dereference as a read operation on its
23032 prefix when operating under -gnatc. Necessary to avoid spurious
23033 'variable assigned but never read' warnings in that mode.
23034 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
23035 is a non-overloaded implicit dereference, call the above subprogram to
23036 ensure proper recording of references.
23038 2004-12-07 Gary Dismukes <dismukes@adacore.com>
23040 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

23088 2004-12-07 Vincent Celier <celier@adacore.com>
23090 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
23091 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
23092 and -eit to -ept. Added qualifier
23093 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
23095 2004-11-27 Andreas Schwab <schwab@suse.de>
23097 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
23099 2004-11-25 Arnaud Charlet <charlet@adacore.com>
23101 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
23102 internal implementation unit GNAT.Sockets.Thin,
23103 as their usage for sockets is non-portable (using the read and write
23104 functions from the system runtime library is fine on UNIX but won't
23105 work under Windows).

23109 2004-11-25 Arnaud Charlet <charlet@adacore.com>

23158 (Setup_Exception): Do nothing in the GNAT SJLJ case.
23160 * gigi.h (others_decl, all_others_decl): New decls representing the
23161 new Others_Value and All_Others_Value objects.
23162 (struct attrib): Rename "arg" component as "args", since GCC expects a
23163 list of arguments in there.
23165 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
23166 corresponding objects exported by a-exexpr, instead of hardcoded dummy
23169 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
23170 others_decl and all_others_decl instead of hardcoded dummy addresses
23171 to represent "others" and "all others" choices, which is cleaner and
23172 more flexible with respect to the possible eh pointer encoding policies.
23174 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
23175 (process_attributes): Account for the naming change of the "args"
23176 attribute list entry component.
23178 * decl.c (build_attr_list): Rename into prepend_attributes to allow
23179 cumulating attributes for different entities into a single list.
23180 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
23181 attributes for the current entity and propagate first subtype
23182 attributes to other subtypes.
23183 <E_Procedure>: Attribute arguments are attr->args and not
23184 attr->arg any more.
23185 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
23186 argument provided, as this is what GCC expects. Use NULL_TREE instead
23189 2004-11-18 Robert Dewar <dewar@adacore.com>
23191 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

23203 procedures factors the common processing for building an RPC receiver
23204 for an RCI package or an RACW type.

23209 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
23211 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
23213 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
23214 distribution subprogram identifiers that are either subprogram numbers
23216 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
23217 string distribution identifiers assigned to a given subprogram.
23218 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
23219 (Add_RAS_Dereference_TSS): Add comments.
23220 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
23221 is not referenced yet because it will be used by the PolyORB DSA
23223 (Insert_Partition_Check): Remove fossile code.
23224 (First_RCI_Subprogram_Id): Document this constant.
23225 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
23227 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
23228 replaced with calls to Get_Library_Unit_Name_String. Previously there
23229 were several instances of the same code in different locations in the
23230 compiler; this checkin completes the replacement of all of these
23231 instances with calls to a common subprogram.
23232 Minor reformatting.
23234 * sem_dist.adb: Remove comment noting that RPC receiver generation
23235 should be disabled for RACWs that implement RASs.
23236 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
23238 * sem_util.ads, sem_util.adb (Has_Stream): New function

23240 qualified name of a library unit into the name buffer.
23241 (Note_Possible_Modification): Generate a reference only
23242 if the context comes from source.
23244 * snames.ads (PCS_Names): New subtype corresponding to names of
23245 supported implementations of the Partition Communication Subsystem
23246 (PCS) (i.e. the runtime library support modules for the distributed

23250 Ed Schonberg <schonberg@adacore.com>
23252 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
23253 (Has_Rep_Pragma): New function
23254 (Has_Attribute_Definition_Clause): New function
23255 (Record_Rep_Pragma): Moved here from sem_ch13.adb
23256 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
23258 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
23260 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
23261 (Expand_Pragma_Psect_Object): New procedure
23262 These procedures contain the revised and cleaned up processing for
23263 these two pragmas. This processing was formerly in Sem_Prag, but
23264 is more appropriately moved here. The cleanup involves making sure
23265 that the pragmas are properly attached to the tree, and that no
23266 nodes are improperly shared.
23268 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
23269 pragmas to Exp_Prag, which is more appropriate.
23270 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
23271 check for duplicates Remove use of Is_Psected flag, no longer needed.
23272 Use new Make_String_Literal function with string.
23274 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
23275 that are functions return universal values, that have to be converted
23276 to the context type.
23277 Use new Make_String_Literal function with string.
23278 (Get_Stream_Convert_Pragma): New function, replaces the use of
23279 Get_Rep_Pragma, which had to be kludged to work in this case.
23281 * freeze.adb: Use new Has_Rep_Pragma function
23283 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
23284 function with string.
23285 Use new Has_Rep_Pragma function.
23287 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
23290 2004-11-18 Robert Dewar <dewar@adacore.com>
23292 * errout.ads, errout.adb: (First_Sloc): New function
23294 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
23295 check (-gnatyx) instead of being included as a redundant construct
23298 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
23299 Style_Check_Order_Subprograms.
23301 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
23302 stylesw.adb: Add Style_Check_Xtra_Parens
23304 * usage.adb: Add line for -gnatyx (check extra parens)
23306 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
23308 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23309 Robert Dewar <dewar@adacore.com>
23311 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
23312 discriminant of a constrained subtype, analyze the copy of the
23313 corresponding constraint, because in some cases it may be only
23314 partially analyzed.
23315 Removes long-lived ??? comments.
23317 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
23318 handled controlled or secondary-stack expressions within the
23319 iteration_scheme of a loop.
23321 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
23322 bounds that may contain functions calls, to prevent memory leaks when
23323 the bound contains a call to a function that uses the secondary stack.
23324 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
23325 generate temporaries for loop bounds that might contain function calls
23326 that require secondary stack and/or finalization actions.
23328 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
23329 selected component and the selector is overloadable (not just a
23330 function) treat as function call, Analyze_Call will disambiguate if
23332 (Analyze_Selected_Component): Do not generate an actual subtype for the
23333 selected component if expansion is disabled. The actual subtype is only
23334 needed for constraint checks.
23335 (Analyze_Allocator): If restriction No_Streams is set, then do
23336 not permit objects to be declared of a stream type, or of a
23337 composite type containing a stream.
23339 * restrict.ads: Remove the a-stream entry from Unit_Array, since
23340 No_Streams no longer prohibits with'ing this package.
23342 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
23343 discriminants, but the parent base has unknown discriminants, there is
23344 no discriminant constraint to inherit. Such a discrepancy can arise
23345 when the actual for a formal type with unknown discriminants is a
23346 similar private type whose full view has discriminants.
23347 (Analyze_Object_Declaration): If restriction No_Streams is set, then
23348 do not permit objects to be declared of a stream type, or of a
23349 composite type containing a stream.
23351 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23353 * exp_dbug.ads: Update documentation to reflect simpler encoding for
23354 protected operations.
23356 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
23357 generated name, it complicates decoding in gdb and hinders debugging
23358 of protected operations.
23359 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
23360 flag for the protected entry barrier function.
23361 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
23362 flag for the protected entry function.

23366 * expect.c: Define __unix__ when __APPLE__ is defined.
23368 * Makefile.in: Inform the value of the variable GMEM_LIB in the
23369 Darwin-specific section.
23371 * lang-specs.h: Change the placement of the %1 marker.
23372 Works around the fact that gcc adds -fPIC by default under Darwin.
23374 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23376 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
23377 type of the object with the packed array type, set the Analyzed flag
23378 on the object if it is an entity or simple indexed component, to avoid
23379 spurious type errors.
23381 2004-11-18 Gary Dismukes <dismukes@adacore.com>
23383 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
23384 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
23385 separate line from the version message.
23387 2004-11-18 Ed Falis <falis@adacore.com>
23389 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
23391 (init_float): Eliminate initialization of floating point status for
23392 AE653. The instructions have no effect for vThreads.
23394 2004-11-18 Vincent Celier <celier@adacore.com>
23396 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
23397 gnatbind is invoked with -shared.
23399 2004-11-18 Jose Ruiz <ruiz@adacore.com>
23401 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
23402 for Detect_Blocking which is redundant with the check done within the
23403 procedure Protected_Single_Entry_Call.
23404 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
23405 Detect_Blocking which is redundant with the check done within the
23406 procedure Protected_Single_Entry_Call.
23408 2004-11-18 Vincent Celier <celier@adacore.com>
23410 * makegpr.adb (Compile): Put the compiling switches (in package
23411 Compiler and on the command line) immediately after "-c", instead of
23412 at the end of the command line invocation of the compiler, when
23413 compiling a non-Ada file.
23414 (Build_Global_Archive): When there is no need to rebuild the archive,
23415 set Global_Archive_Exists, so that the archive is passed to the linker
23418 2004-11-18 Robert Dewar <dewar@adacore.com>
23419 Sergey Rybin <rybin@adacore.com>
23422 Remove extra paren check from list of checks for redundant constructs
23423 Add documentation of new -gnatyx style check (check extra parens)
23424 Remove paragraph about gnatelim debug options.
23426 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
23427 objects rather than forbidding dependencies on the package Ada.Streams.
23429 * sinfo.ads: Add ??? note that we should document pragmas passed to
23432 * g-expect.ads: Fix a few typos in the comments.
23434 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
23436 * misc.c (gnat_handle_option): Use %< and %> for quoting in
23439 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
23441 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
23443 2004-11-07 Andreas Schwab <schwab@suse.de>
23445 * Makefile.in (install-gnatlib): Remove spurious hyphen.
23447 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
23450 * Makefile.in (darwin): Set soext to .dylib.
23452 2004-10-26 Vincent Celier <celier@gnat.com>
23453 Thomas Quinot <quinot@act-europe.fr>
23455 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
23456 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
23457 there is no use of GNAT.Sockets.Constants.
23458 Remove remaining pragma Import for C_Write
23459 Remove C_Read and C_Write from internal implementation unit
23460 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
23461 the read and write functions from the system runtime library is fine
23462 on UNIX but won't work under Windows).
23464 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
23465 (Check_Selector): Use C_Recv instead of C_Read.
23466 Selectors are the GNAT.Sockets abstraction to perform a select()
23467 call on a set of descriptors. To allow abortion of an ongoing
23468 select operation, some data is written to a dedicated socket that
23469 is always monitored.
23470 Under Windows, the write and read library functions cannot operate
23471 on sockets, so we need to use send and recv instead, which is portable
23472 across all supported platforms.
23474 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
23475 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
23476 (using the read and write functions from the system runtime library is
23477 fine on UNIX but won't work under Windows).
23479 2004-10-26 Nicolas Setton <setton@act-europe.fr>
23481 * mlib-tgt-darwin.adb: New file.
23483 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
23484 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
23485 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
23486 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
23489 * Makefile.in: Add support for building shared libraries under Darwin.
23490 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
23491 the low level EH init subprogram to be called from __gnat_initialize.
23493 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
23494 indicates which options to pass to the archive indexer.
23496 * mlib-utl.adb: Add support for calling ranlib with additional
23497 options. This is needed for instance under Mac OS X.
23498 (Ranlib_Options): New global variable, used to store the potential
23499 options to pass to ranlib.
23500 (Ar): Use Ranlib_Options when spawning ranlib.
23501 (Initialize): Set the value of ranlib option.
23503 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
23505 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
23506 instead of 8K, to reflect the real potential needs for stack-checking
23509 2004-10-26 Pascal Obry <obry@gnat.com>
23511 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
23513 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
23514 Windows only the initial thread stack size can be set so it is good to
23515 start we a low stack size.
23516 The OS will adjust the size as needed.
23518 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
23519 Nicolas Setton <setton@act-europe.fr>
23521 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
23522 "__unix__" instead of "unix".
23523 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
23524 sections were just mistakenly ignored. The former is
23525 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
23526 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
23527 of hpux. This prevents an unwanted definition of the symbol
23528 convert_addresses in adaint.o.
23530 2004-10-26 Gary Dismukes <dismukes@gnat.com>
23532 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
23533 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
23535 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23537 * a-filico.ads, a-filico.adb: fix incorrect header.
23539 2004-10-26 Javier Miranda <miranda@gnat.com>
23541 * a-ststio.ads: Fix typo in identifier
23543 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23545 * sem_ch4.adb: Minor reformatting.
23547 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23549 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
23550 enabled, check the result of unary and binary operations when the
23551 expression is the right-hand side of an assignment.
23553 2004-10-26 Vincent Celier <celier@gnat.com>
23555 * clean.adb (Delete): Do not output warnings when in quiet output and
23556 not in verbose mode.
23557 (Force_Deletions): New Boolean flag, defaulted to False
23558 (Delete): Only delete a file if it is writable, and when
23559 Force_Deletions is True.
23560 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
23561 (Usage): Line for new switch -f
23562 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
23565 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23567 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
23568 JM type only if its size matches that of the wrapper. When a size is
23569 prescribed and the field is not aliased, remove the wrapper of a JM
23570 type only if the size is not greater than that of the packed array.
23571 (gnat_to_gnu_entity): Change the extension of packed array wrappers
23574 2004-10-26 Geert Bosch <bosch@gnat.com>
23576 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
23577 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
23578 (Pred): Implement in terms of Succ.
23580 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23582 * exp_aggr.adb (Safe_Component): An aggregate component that is an
23583 unchecked conversion is safe for in-place use if the expression of the
23584 conversion is safe.
23585 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
23586 be expandable in place even if the aggregate does not come from source.
23587 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
23588 designated object of an allocator in place, rather than building it
23589 first on the stack. The previous scheme forces a full copy of the array,
23590 and may be altogether unsusable if the size of the array is too large
23591 for stack allocation.
23593 2004-10-26 Robert Dewar <dewar@gnat.com>
23595 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
23596 compares if the component is atomic.
23598 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
23599 array assignment if the component type is atomic.
23601 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23602 Eric Botcazou <ebotcazou@act-europe.fr>
23604 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
23605 is aliased and is a by_reference type, do not pass by copy.
23606 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
23607 detect whether the call is in the right side of an assignment or
23608 the expression of an object declaration. Recurse on component
23609 association within aggregates.
23610 Call it in the condition that determines whether the temporary is
23611 necessary for correct stack-checking.
23613 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23615 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
23616 RACW_Type, used in the PolyORB version.
23617 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
23618 version and the GARLIC version.
23620 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
23621 Rename RCI_Info to RCI_Locator for better consistency between the
23622 GARLIC and PolyORB versions of the distributed systems annex.
23623 (DSA_Implementation_Name): This enumeration lists the possible
23624 implementations of the Partition Communication Subsystem for the
23625 Distributed Systems Annex (DSA). The three available implementations
23626 are the dummy stub implementation (No_DSA), and two versions based on
23627 two different distribution runtime libraries: GARLIC and PolyORB. Both
23628 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
23630 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
23633 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
23634 between the GARLIC and PolyORB versions of the distributed systems
23636 Remove RE_Unbounded_Reclaim_Pool since it is unused.
23638 2004-10-26 Gary Dismukes <dismukes@gnat.com>
23640 * gnat1drv.adb: Suppress calling the back end when
23641 Frontend_Layout_On_Target is true.
23643 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23645 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
23646 Set_Read_Only): New subprograms.
23647 These new routines allow the user to set or unset the Owner execute
23648 and Owner write permission flags on a file.
23650 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
23651 GNAT.OS_Lib.Set_Executable instead of rolling our own.
23653 2004-10-26 Matthew Gingell <gingell@gnat.com>
23655 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
23657 2004-10-26 Pascal Obry <obry@gnat.com>
23659 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
23660 memory before the faulting page we properly test the process read
23661 access for this address using appropriate Win32 routine.
23662 (HPUX sections): guard with "__hpux__" instead of "hpux".
23664 2004-10-26 Robert Dewar <dewar@gnat.com>
23666 * lib-xref.adb (Generate_Reference): Don't complain about reference to
23667 entry parameter if pragma Unreferenced set, since we do not properly
23668 handle the case of multiple parameters.
23670 2004-10-26 Vincent Celier <celier@gnat.com>
23672 * prj-env.adb: (Contains_ALI_Files): New Boolean function
23673 (Ada_Objects_Path.Add): For a library project, add to the object path
23674 the library directory only if there is no object directory or if the
23675 library directory contains ALI files.
23676 (Set_Ada_Paths.Add.Recursive_Add): Ditto
23678 2004-10-26 Vincent Celier <celier@gnat.com>
23680 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
23681 extension of library projects.
23683 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
23684 path defaults to ".:<prefix>/lib/gnat".
23685 (Parse): For an extending all project, allow direct import of a project
23686 that is virtually extended.
23688 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
23689 the specified name is directly imported, return its ID. Otherwise, if
23690 an extension of this project is imported, return the ID of the
23693 2004-10-26 Robert Dewar <dewar@gnat.com>
23695 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
23696 (Sub3): New procedure, used by Scaled_Divide
23697 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
23698 correct more than one instance of failure to propagate carries
23700 (Double_Divide): Handle overflow case of largest negative number
23701 divided by minus one.
23703 * s-arit64.ads (Double_Divide): Document that overflow can occur in
23704 the case of a quotient value out of range.
23707 2004-10-26 Robert Dewar <dewar@gnat.com>
23709 * s-bitops.adb (Bit_Eq): Remove redundant check.
23711 * s-bitops.ads: Minor comment updates
23712 Change some occurrences of Address to System.Address
23714 * s-carsi8.ads: Fix minor cut-and-paste error in comments
23716 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23718 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
23719 accessibility check to prefix that is a protected operation.
23721 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23723 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
23724 empty, post message on stub.
23726 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23727 Javier Miranda <miranda@gnat.com>
23729 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
23730 current instance appears within a unit that is directly in the context
23732 Used to determine whether the body of the instance should be analyzed
23733 immediately after its spec, to make its subprogram bodies available
23734 for front-end inlining.
23735 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
23736 constraint is not allowed on the component type (AARM 12.5.3(3))
23738 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23740 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
23741 'Storage_Pool): enhance, document & limit detection of non-sharable
23744 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
23746 * s-pooglo.ads: Add more documentation now that this pool is properly
23749 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23751 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
23752 or protected type with discriminants, do not constrain the
23753 corresponding record type if the subtype declaration has no
23754 discriminant constraints. This can be the case in source code, or in
23755 the subtype declaration created to rename an actual type within an
23758 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23760 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
23761 different kind of stub (possibly wrong name for file), do not check
23763 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
23764 includes call to some function that returns an unconstrained type, do
23767 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23769 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
23770 appear in the code for the main unit. Dependencies among units in the
23771 context of the main unit are established when those other units are
23772 compiled. Otherwise spurious elaboration constraints can generate
23773 incorrect elaboration circularities.
23775 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23776 Ed Schonberg <schonberg@gnat.com>
23778 * sem_util.adb (Is_Aliased_View): Defend against the case where this
23779 subprogram is called with a parameter that is not an object name. This
23780 situation arises for some cases of illegal code, which is diagnosed
23781 later, and in this case it is wrong to call Is_Aliased, as that might
23782 cause a compiler crash.
23783 (Explain_Limited_Type): Refine previous fix to include
23784 inherited components of derived types, to provide complete information.
23786 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
23787 is the prival for a protected object.
23788 It is necessary to mark this entity as a variable, in addition to
23789 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
23790 modified to avoid checking the Aliased flag on entities that are not
23791 objects. (Checking that flag for non-objects is erroneous and could
23792 lead to a compiler crash).
23794 2004-10-26 Robert Dewar <dewar@gnat.com>
23796 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
23797 X_Frac = 0.5, then we know that the number X must be positive.
23798 (Succ): Remove the same redundant test, and also fix the primary test
23799 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
23801 (Decompose): Add fuller comments to spec
23803 2004-10-26 Pascal Obry <obry@gnat.com>
23805 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
23806 validity (process must have read access). Set to 0 in all other cases.
23807 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
23808 violation on Win32.
23809 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
23810 segmentation violation.
23812 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23814 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
23815 whose type is a constructed subtype of an aliased object with an
23816 unconstrained nominal subtype, convert the actual to the constructed
23817 subtype before taking its address.
23819 2004-10-26 Vincent Celier <celier@gnat.com>
23821 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
23822 (Is_Path_Name_Case_Sensitive): New function
23824 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
23825 (Base_Name, Simple_Name, Current_Directory, Compose,
23826 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
23829 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23830 Vasiliy Fofanov <fofanov@act-europe.fr>
23831 Vincent Celier <celier@gnat.com>
23833 * gnat_ugn.texi: Generalize "finding memory problems" section into a
23834 "memory management issues" section and document some of the useful
23835 memory pools provided as part of the GNAT library.
23836 Remove "virtual" from declaration of A::method2 in
23837 the simple example of Ada/C++ mixed system.
23838 Library Projects may be virtually extended: their virtual extensions
23839 are not Library Projects.
23840 Added section on extending project hierarchies.
23842 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
23844 * adaint.c (__gnat_get_libraries_from_registry): Cast value
23846 (__gnat_portable_spawn): Remove const.
23848 * mingw32.h (MAXPATHLEN): Check for previous definition.
23850 2004-10-17 Matthias Klose <doko@debian.org>
23852 * gnatvsn.ads: Set gnat library version to 4.0.
23854 2004-10-05 Vincent Celier <celier@gnat.com>
23856 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
23858 2004-10-04 Laurent Guerby <laurent@guerby.net>
23861 * Makefile.in: Define and use RANLIB_FLAGS.
23863 2004-10-04 Pascal Obry <obry@gnat.com>
23865 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
23866 other x86 platforms).
23868 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23870 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
23871 in general and triggers stack alignment adjustment for thread entry
23872 points on targets where this is necessary.
23874 2004-10-04 Bernard Banner <banner@gnat.com>
23877 * Makefile.in: Add section for powerpc linux
23878 Add variant i-vxwork-x86.ads
23880 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
23882 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23884 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
23885 table registration calls when need be. Ensures no reference to the crt
23886 ctors symbol are issued in the SJLJ case, which avoids possible
23887 undefined symbol errors in the case of modules to be statically linked
23890 2004-10-04 Javier Miranda <miranda@gnat.com>
23892 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
23893 in-line the code corresponding to subprogram Analyze_Actuals. In
23894 addition, analyze the actuals only in case of subprogram call.
23896 2004-10-04 Ed Falis <falis@gnat.com>
23898 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
23900 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
23902 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
23903 in the documentation.
23905 2004-10-04 Robert Dewar <dewar@gnat.com>
23907 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
23909 (Analyze_Block_Statement): Add circuitry to detect following dead code
23910 (Check_Unreachable_Code): Handle case of block exit
23912 2004-10-04 Robert Dewar <dewar@gnat.com>
23914 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
23915 (XMatchD): Avoid warning for Logic_Error call
23917 2004-10-04 Robert Dewar <dewar@gnat.com>
23919 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
23920 consider expressions buried within a procedure actual to be an actual.
23921 This caused some blowups with uses of packed slices within a procedure
23924 2004-10-04 Robert Dewar <dewar@gnat.com>
23926 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
23927 longer need to be initialized to zero.
23928 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
23929 initialized to zero.
23931 * checks.adb (Expr_Known_Valid): Packed arrays are now always
23932 considered valid, even if the representation is modular. That's correct
23933 now that we no longer initialize packed modular arrays to zero.
23935 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
23936 suffixes. These are now documented as the only cases in which the
23937 debugger ignores outer records.
23938 Previously, the spec allowed arbitrary suffixes for this purpose.
23939 Change name of LJM to JM for packed array pad records
23940 Create separate section on packed array handling, and add a whole new
23941 set of comments to this section describing the situation with packed
23942 modular types and justification requirements depending on endianness.
23944 2004-10-04 Robert Dewar <dewar@gnat.com>
23946 * a-except.adb: Add a comment for last change
23948 * einfo.ads: Minor spelling correction in comment
23950 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
23952 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
23955 * sem_util.ads: Minor comment update
23957 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23959 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
23960 Inline_Always when in Configurable_Run_Time mode.
23962 * sem_prag.adb (Process_Convention): If entity is an inherited
23963 subprogram, apply convention to parent subprogram if in same scope.
23964 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
23965 when in Configurable_Run_Time mode.
23967 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23969 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
23970 class_wide type after component list has been inherited.
23972 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23974 * sem_ch12.adb (Check_Generic_Actuals): New predicate
23975 Denotes_Previous_Actual, to handle properly the case of a private
23976 actual that is also the component type of a subsequent array actual.
23977 The visibility status of the first actual is not affected when the
23978 second is installed.
23979 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
23980 make fully recursive the treatment of formals of packages declared
23982 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
23983 the above on exit from an instantiation.
23984 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
23985 current instantiation which is now complete.
23986 (Analyze_Package_Instantiation): No instantiated body is needed if the
23987 main unit is generic. Efficient, and avoid anomalies when a instance
23988 appears in a package accessed through rtsfind.
23990 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23992 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
23993 do not generate a declaration for a temporary if the call is part of a
23994 library-level instantiation.
23996 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23998 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
23999 searching for a limited component to flag.
24001 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
24002 expansion of Input, to account for the fact that the implicit call
24003 generated by the attribute reference must freeze the user-defined
24004 stream subprogram. This is only relevant to 'Input, because it can
24005 appear in an object declaration, prior to the body of the subprogram.
24007 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
24008 expansion can proceed and further errors uncovered.
24009 (Minor clean up): Fix cases of using | instead of \ for continuation
24012 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24014 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
24016 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
24017 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
24018 Use gcc_assert and gcc_unreachable.
24020 * decl.c (gnat_to_gnu_entity, case object): Check and process a
24021 specified alignment before validating size.
24022 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
24023 stripped-down declaration for the type of the inner field when making
24026 * utils.c (finish_record_type): Do not compute the size in units
24027 incrementally. Instead compute it once for the rep clause case.
24028 Use gcc_assert and gcc_unreachable.
24030 2004-10-04 Vincent Celier <celier@gnat.com>
24032 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
24034 (Is_Valid_Path_Name): Take '/' as a directory separator.
24036 2004-10-04 Vincent Celier <celier@gnat.com>
24038 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
24039 (Extended_Project) only if Extended_Project is defined, to avoid
24041 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
24043 (Parse_Single_Project): Ditto.
24045 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
24046 Add_To_Project_Path for virtual projects.
24048 2004-10-04 Vincent Celier <celier@gnat.com>
24050 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
24051 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
24052 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
24053 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
24054 parameter Options_2.
24056 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
24057 Build_Dynamic_Library with an empty Options_2.
24059 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
24062 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
24063 directory separator, if any.
24064 (Gprmake): Do not allow mains on the command line for library projects.
24065 Do not attempt to link when the project is a library project.
24066 (Library_Opts): New table to store Library_Options.
24067 (Build_Library): If Library_Options is specified, pass these options
24068 when building a shared library.
24070 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
24072 * s-tposen.adb (Service_Entry): The object must be always unlocked at
24073 the end of this procedure now that the unlock operation was inserted
24076 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
24078 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
24079 corresponding to the Preallocated_Stacks flags in System.
24080 (Get_Target_Parameters): Including the processing for
24081 Preallocated_Stacks.
24083 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
24084 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

24091 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
24092 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
24093 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
24094 used to signal whether the compiler creates the required stacks and
24095 descriptors for the different tasks (when True) or it is done by the
24096 underlying operating system at run time (when False).
24097 It is initially set to False in all targets.
24099 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
24100 if it is supported by the target.
24101 (Make_Task_Create_Call): Pass the stack address if it has been
24102 previously created. Otherwise pass a Null_Address.
24104 * snames.adb: Add _stack.
24106 * snames.ads: Add Name_uStack. Required to allow the expander to
24107 statically allocated task stacks.
24109 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
24110 Stack_Address argument.
24111 Check that its value is equal to Null_Address because this target does
24112 not support the static stack allocation.
24114 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
24116 * usage.adb: Change "pragma inline" to "pragma Inline" in information
24119 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
24121 * exp_dist.adb: Split declaration of asynchronous flag out of
24122 Add_RACW_Read_Attribute.
24123 Minor reformatting for better alignment with PolyORB version.
24124 Store the entity for the asynchronous flag of an RACW, rather than the
24125 expression, in the asynchronous flags table. This will allow this flag
24126 to be used in other subprograms beside Add_RACW_Read_Attribute.
24128 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
24130 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
24131 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
24132 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
24133 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
24134 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
24135 sockets constant MSG_NOSIGNAL (Linux-specific).
24136 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
24137 all Send operations.
24138 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
24139 from trigerring SIGPIPE.
24140 Rename components to avoid clash with Ada 2005 possible reserved
24142 (Check_Selector): When the select system call returns with an error
24143 condition, propagate Socket_Error to the caller.
24145 2004-10-01 Jan Hubicka <jh@suse.cz>
24147 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
24149 2004-09-23 Robert Dewar <dewar@gnat.com>
24152 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
24153 instead do this at freeze time (we won't do it if there is an address
24155 Change "pragma inline" to "pragma Inline" in information and error
24157 Minor reformatting.
24159 * freeze.adb (Check_Address_Clause): Remove previous change, not the
24160 right way of doing things after all.
24161 (Freeze_Entity): For object, set Is_Public for imported entities
24162 unless there is an address clause present.
24164 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
24166 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
24167 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
24168 ensures proper handling of types with rep clauses, which might have
24169 their TYPE_SIZE set already.
24171 2004-09-21 Robert Dewar <dewar@gnat.com>
24173 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
24174 packed array types in both little- and big-endian cases. This change
24175 ensures that we no longer count on the unused bits being initialized
24176 for such types (and in particular ensures that equality testing will
24177 only read the relevant bits).
24178 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
24179 These changes mean that we no longer need to initialize small packed
24181 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
24182 optimization to an LJM field as to its parent field.
24184 * ada-tree.h, trans.c, utils.c, utils2.c:
24185 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
24187 2004-09-20 Jan Hubicka <jh@suse.cz>
24189 * utils.c (gnat_finalize): Remove.
24190 (end_subprog_body): Directly call cgraph_finalize_function;
24191 do not lower the nested functions.
24193 2004-09-20 Robert Dewar <dewar@gnat.com>
24196 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public

24248 (Attrs, Package_Attributes): Table instantiations moved from the body to
24249 the private part to be accessible from Prj.Attr.PM body.

24309 raise Program_Error if called from a protected operation.
24311 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
24312 the protected action nesting level.
24313 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
24314 protected action nesting level.
24315 (Unlock): When pragma Detect_Blocking is active decrease the protected
24316 action nesting level.
24318 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
24319 Protected_Action_Nesting.
24321 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
24322 Common_ATCB record. It contains the dynamic level of protected action
24323 nesting for each task. It is needed for checking whether potentially
24324 blocking operations are called from protected operations.
24325 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
24326 Detect_Blocking is active or not in the partition.
24328 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

24362 contains the required machinery for handling that.
24364 * sem_util.ads: Change comment associated to procedure
24365 Check_Potentially_Blocking_Operation.
24366 This procedure does not insert a call for raising the exception because
24367 that is currently done by the run time.
24369 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
24371 * init.c: Add the global variable __gl_detect_blocking that indicates
24372 whether pragma Detect_Blocking is active (1) or not (0). Needed for
24373 making the pragma available at run time.
24374 (__gnat_set_globals): Pass and update the detect_blocking parameter.

24377 pragma Detect_Blocking is active.
24379 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
24381 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
24382 DB is found in the ali file. Any unit compiled with pragma
24383 Detect_Blocking active forces its effect in the whole partition.
24385 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
24386 Detect_Blocking is active and delay is called from a protected
24389 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
24390 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
24391 Detect_Blocking is active (0 otherwise).
24392 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
24393 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

24403 (Register_Receiving_Stub): Add Subp_Info formal parameter.
24404 Update API in placeholder implemetation of s-parint to reflect changes
24405 in distribution runtime library.
24407 * sem_ch3.adb (Expand_Derived_Record): Rename to
24408 Expand_Record_Extension.
24410 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
24411 primitive operations of potentially distributed object types that have
24412 non-controlling anonymous access formals.
24414 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
24416 New implementation of expansion for remote access-to-subprogram types,
24417 based on the RACW infrastructure.
24418 This version of sem_dist is compatible with PolyORB/DSA as well as
24421 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
24422 Asynchrronous that applies to a remote access-to-subprogram type, mark
24423 the underlying RACW type as asynchronous.
24425 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
24426 __gnat_using_gnu_linker to 1.
24428 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
24429 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

24435 * exp_ch3.adb (Expand_Derived_Record): Rename to
24436 Expand_Record_Extension.
24437 (Build_Record_Init_Proc.Build_Assignment): The default expression in
24438 a component declaration must remain attached at that point in the
24439 tree so New_Copy_Tree copies it if the enclosing record type is derived.
24440 It is therefore necessary to take a copy of the expression when building
24441 the corresponding assignment statement in the init proc.
24442 As a side effect, in the case of a derived record type, we now see the
24443 original expression, without any rewriting that could have occurred
24444 during expansion of the ancestor type's init proc, and we do not need
24445 to go back to Original_Node.
24447 * exp_ch3.ads (Expand_Derived_Record): Rename to
24448 Expand_Record_Extension.
24450 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

24453 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
24454 New subprograms. Used to create a proxy tagged object for a remote
24455 subprogram. The proxy object is used as the designated object
24456 for RAS values on the same partition (unless All_Calls_Remote applies).
24457 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
24458 System.Partition_Interface.Get_Unique_Remote_Pointer.
24459 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
24460 Renamed from Add_RAS_*_Attribute.
24461 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
24463 New implementation of expansion for remote access-to-subprogram types,
24464 based on the RACW infrastructure.
24466 * exp_dist.ads (Copy_Specification): Update comment to note that this
24467 function can copy the specification from either a subprogram
24468 specification or an access-to-subprogram type definition.
24470 2004-09-09 Ed Schonberg <schonberg@gnat.com>
24472 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
24473 in an instance, between an explicit subprogram an one inherited from a
24474 type derived from an actual.
24476 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
24477 add a polling call if the subprogram is to be inlined by the back-end,
24478 to avoid repeated calls with multiple inlinings.
24480 * checks.adb (Apply_Alignment_Check): If the expression in the address
24481 clause is a call whose name is not a static entity (e.g. a dispatching
24482 call), treat as dynamic.

24486 * g-trasym.ads: Minor reformatting
24488 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

24497 2004-09-09 Pascal Obry <obry@gnat.com>
24499 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
24500 enable map file generation. Add the right option to generate the map
24501 file if Map_File is set to True.
24503 * gnatdll.adb (Gen_Map_File): New variable.
24504 (Syntax): Add info about new -m (Map_File) option.

24532 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
24533 of variable length temporaries for function return now that the
24534 back-end and gigi support it.

24611 consistent treatment of entity references contained within the
24612 enclosed procedure call.
24614 2004-09-01 Vincent Celier <celier@gnat.com>
24616 * bindgen.adb: (Set_EA_Last): New procedure
24617 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

24728 for a global aliased object with a variable size and an unconstrained
24729 nominal subtype, pretend there is no initializer if the one we have is
24730 incomplete, and avoid referencing an inexistant component in there. The
24731 part we have will be rebuilt anyway and the reference may confuse

24755 unit, this is an attempt to inline a construct that is not available in
24756 the current restricted mode, so abort rather than trying to continue.
24758 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
24759 discriminants that rename those of the parent, recover names of
24760 original discriminants for the constraint on the full view of the

24790 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
24791 returning C.int, to avoid using a derived boolean type.
24793 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
24794 Duplicate_Subexpr_No_Checks in preference to direct use of

24822 ignore overflows on low and high bounds of an index to also account for
24823 differences in signedness between sizetype and gnu_index_subtype.
24824 These are as legitimate as the ones caused by a lower TYPE_PRECISION

27145 2004-05-14 Robert Dewar <dewar@gnat.com>
27147 * gnat_ugn.texi: Minor change to -gnatS documentation
27149 * sprint.adb: Remove some instances of Assert (False) and for this
27150 purpose replace them by output of a ??? string.
27152 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
27155 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
27156 flag processing. This was suppressing required dependencies in
27157 No_Run_Time mode and is not needed since the binder does not generate
27158 references for things in libgnat anyway.
27160 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
27163 2004-05-14 Thomas Quinot <quinot@act-europe.fr>
27165 * gnat_ugn.texi: Document AIX-specific issue with initialization of
27168 * exp_ch4.adb (Insert_Dereference_Action): Do not generate dereference
27169 action for the case of an actual parameter in an init proc call.
27171 2004-05-14 Ed Schonberg <schonberg@gnat.com>
27173 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
27174 subtype, check visible entities in base type.
27176 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
27177 actions if the object is a renaming.
27179 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
27180 Check_Formal_Package_Instance, to determine more precisely when the
27181 formal and the actual denote the same entity.
27183 2004-05-14 Javier Miranda <miranda@gnat.com>
27185 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
27187 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
27188 corresponding to a private_with must be removed from visibility; it
27189 will be made visible later, just before we analyze the private part of
27191 (Check_Private_Child_Unit): Allow private_with clauses in public
27193 (Install_Siblings): Make visible the private entities of private-withed
27195 (Install_Withed_Unit): Do not install the private withed unit if we
27196 are compiling a package declaration and the Private_With_OK flag was
27197 not set by the caller. These declarations will be installed later,
27198 just before we analyze the private part of the package.
27200 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
27201 during the evaluation of the expression that initializes the object,
27202 decorate it with the expected type to avoid cascade errors.
27205 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
27206 subprogram we have to install the private_with clauses after its
27207 specification has been analyzed (as documented in AI-262.TXT).
27209 * sem_ch8.adb (Has_Private_With): New function. Determines if the
27210 current compilation unit has a private with on a given entity.
27211 (Find_Direct_Name): Detect the Beaujolais problem described in
27214 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
27215 provides the functionality of the function Is_Ancestor that was
27216 previously available in sem_ch10. It has been renamed to avoid
27219 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
27221 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27223 * utils.c (build_vms_descriptor): Use SImode pointers.
27225 2004-05-14 Vasiliy Fofanov <fofanov@act-europe.fr>
27227 * gnat_ugn.texi: Revised chapter "GNAT and Libraries".
27229 2004-05-14 GNAT Script <nobody@gnat.com>
27231 * Make-lang.in: Makefile automatically updated
27233 2004-05-14 Arnaud Charlet <charlet@act-europe.fr>
27235 Renaming of target specific files for clarity

27381 2004-05-13 Diego Novillo <dnovillo@redhat.com>
27383 Merge from tree-ssa-20020619-branch.
27385 * config-lang.in (boot_language, build_by_default): Set
27387 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
27388 (max_size): Add static chain op for call_expr.
27390 2004-05-12 Richard Sandiford <rsandifo@redhat.com>

27397 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a
27400 2004-05-10 Doug Rupp <rupp@gnat.com>
27402 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
27405 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
27407 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
27409 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
27410 Fixes undefined symbols in IA64 gnatlib.
27412 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
27414 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
27415 Short_Address). This will be moved to system.auxdec.
27417 2004-05-10 Thomas Quinot <quinot@act-europe.fr>
27419 * sem_util.adb: Replace test for presence of a node that is always
27420 present with a call to Discard_Node.
27422 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
27423 Analyze on the library unit node after generation of distribution stub
27424 constructs. The call was a no-op because Unit_Node has already been
27425 Analyzed, and the tree fragments for the distribution stubs are
27426 analyzed as they are inserted in Exp_Dist.
27427 Update comment regarding to distribution stubs to reflect that we
27428 do not generate stub in separate files anymore.
27430 * einfo.ads: Clarify the fact that a tagged private type has the
27431 E_Record_Type_With_Private Ekind.
27433 * erroutc.adb: Minor reformatting
27435 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
27436 values if line length is increased using -gnatyM (noticed during code
27439 * eval_fat.adb: Minor reformatting
27440 Put spaces around exponentiation operator
27442 2004-05-10 Ed Schonberg <schonberg@gnat.com>
27445 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
27446 has been rewritten as an explicit dereference, retrieve type of
27447 original node to check for possibly unconstrained record type.
27449 2004-05-10 Ed Schonberg <schonberg@gnat.com>
27451 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
27452 overriding, use the operation of the parent unconditionally.
27454 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
27455 operation when either operand is a literal, to avoid further
27458 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
27459 overridden by a previous explicit declaration, mark the previous entity
27462 * sem_disp.adb (Check_Dispatching_Operation): New predicate
27463 Is_Visibly_Controlled, to determine whether a declaration of a
27464 primitive control operation for a derived type overrides an inherited
27465 one. Add warning if the explicit declaration does not override.
27467 2004-05-10 Vincent Celier <celier@gnat.com>
27469 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
27470 some cases when the sources are no longer present.
27472 * make.adb (Collect_Arguments): Fail if an external source, not part
27473 of any project need to be compiled, when switch -x has not been
27476 * makeusg.adb: Document new switch -x
27478 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
27479 defaulted to False.
27481 * switch-m.adb (Scan_Make_Switches): New switch -x
27483 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
27484 gnatmake switch -x.
27486 * gnat_ugn.texi: Document new gnatmake switch -x
27488 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
27490 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
27492 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
27493 (process_attributes): Likewise.
27495 2004-05-10 Joel Brobecker <brobecker@gnat.com>
27497 * s-inmaop.ads: Fix spelling mistake in one of the comments.
27499 2004-05-10 Robert Dewar <dewar@gnat.com>

28596 * sem_prag.adb (Set_Exported): Warn about making static as result of
28597 export only when the export is coming from source. This may be not
28598 be true e.g. on VMS where we expand export pragmas for exception codes
28599 together with imported or exported exceptions, and we don't want the
28600 user to be warned about something he didn't write.
28602 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
28604 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
28605 duplication between normal entities and those declared as renamings.

28674 * make.adb (Scan_Make_Arg): Pass any -fxxx switches to gnatlink, not
28675 just to the compiler.

28704 (Leading_Part): Still perform truncation to machine number if the
28705 specified radix_digits is greater or equal to machine_mantissa.
28707 2004-04-05 Javier Miranda <miranda@gnat.com>
28709 * par-ch3.adb: Complete documentation of previous change
28710 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

28723 as is done for non-private derived record types.
28725 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
28726 Ada 2005 AI-310: an abstract non-dispatching operation is not a

28735 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
28736 statement whose right-hand side is an inlined call, save a copy of the
28737 original assignment subtree to preserve enough consistency for
28738 Analyze_Assignment to proceed.
28740 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
28741 complete assignment subtree which is now unnecessary, as the expansion
28742 of inlined call has been improved to preserve a consistent assignment
28743 tree. Note_Possible_Modification must be called only
28744 after checks have been applied, or else unnecessary checks will
28747 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
28748 of explicit dereferences that do not Come_From_Source:
28749 - be selective on cases where we must go back to the dereferenced
28750 pointer (an assignment to an implicit dereference must not be
28751 recorded as modifying the pointer);
28752 - do not rely on Original_Node being present (Analyze_Assignment
28753 calls Note_Possible_Modification on a copied tree).
28755 * sem_warn.adb (Check_References): When an unset reference to a pointer
28756 that is never assigned is encountered, prefer '<pointer> may be null'

28767 libexc. We currently don't reference anything in this library and
28768 linking it in triggers linker warnings we don't want to see.

28819 non-static when building aggregate for bit-packed array.
28821 * exp_ch4.adb (Expand_N_Slice): If a packed slice is an actual of a
28822 function call that is itself the actual in a procedure call, build
28825 * exp_pakd.adb (Expand_Bit_Packed_Element_Set): If right-hand side is
28826 a string literal, create a temporary for it, constant folding only
28827 handles scalars here.
28829 2004-04-01 Vincent Celier <celier@gnat.com>

29010 allows to configure paths for an executable name (gnatmake) different
29011 from the current one (gnatdist).
29013 2004-03-29 Ed Schonberg <schonberg@gnat.com>
29015 * exp_ch6.adb (Expand_Call): A call to a function declared in the
29016 current unit cannot be inlined if it appears in the body of a withed
29017 unit, to avoid order of elaboration problems in gigi.
29019 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
29020 information for protected (wrapper) operation as well, to simplify gdb
29023 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
29024 protected body, indicate that the entity for the generated spec comes

29066 a classwide type (for which Is_Object_Reference holds), but it can
29067 also be a value conversion for an access-to-classwide type. In the
29068 latter case, there is an implicit dereference, and the original node
29069 for the prefix does not verify Is_Object_Reference.
29071 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view

29096 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
29097 value expressions to ensure that calls within a component definition
29098 will be checked (since those are evaluated during the record type's
29101 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>

29145 case when the source contains only comments.
29147 2004-03-22 Ed Schonberg <schonberg@gnat.com>
29149 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
29150 declaration for a child subprogram body that acts as a spec, indicate
29151 that the entity in the declaration needs debugging information.
29153 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
29154 full view if the subtype is created for a constrained record component;
29155 gigi has enough information to construct the record, and there is no
29156 place in the tree for the declaration.
29158 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
29159 serial number for the dummy body that is built for analysis, to avoid
29160 inconsistencies in the generation of internal names when compiling
29163 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
29165 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
29168 2004-03-22 GNAT Script <nobody@gnat.com>

29197 Minor reformatting.
29199 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
29201 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
29202 as regular exception objects and not as mere integers representing the
29203 condition code. The latter approach required some dynamics to mask off
29204 severity bits, which did not fit well into the GCC table based model.
29205 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
29206 exception data objects. We don't it and it would conflict with the other
29207 external symbol we have to generate for such exceptions.
29209 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
29210 the special code for VMS exceptions, since these are now represented
29211 as regular exceptions objects.
29213 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29215 * decl.c (debug_no_type_hash): Remove.

29219 2004-03-19 Laurent Guerby <laurent@guerby.net>
29221 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
29222 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
29224 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29226 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
29227 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
29228 (TYPE_RM_SIZE_INT): Directly use type.values.
29229 (TREE_LOOP_ID): Clean up check.
29230 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
29231 TYPE_VALUES, not TYPE_FIELDS.

29244 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
29246 * adaint.c: Update comments.
29248 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
29249 GNATLIB_SHARED for FreeBSD.
29251 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
29253 * init.c [VxWorks]: Do not fix the stack size for the environment task.
29254 When needed (stack checking) the stack size is retrieved
29255 from the VxWorks kernel.
29257 * Makefile.in: Flag -nostdinc is required when building the run time
29258 for avoiding looking for files in the base compiler.
29259 Add the VxWorks specific version of the package body for
29260 System.Stack_checking.Operations (5zstchop.adb).
29262 * Make-lang.in: Add the object file for
29263 System.Stack_Checking.Operations.
29265 * Makefile.rtl: Add object file for the package
29266 System.Stack_Checking.Operations.
29268 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
29270 * s-stache.ads, s-stache.adb: Move the operations related to stack
29271 checking from this package to package System.Stack_Checking.Operations.
29272 This way, stack checking operations are only linked in the final
29273 executable when using the -fstack-check flag.
29275 2004-03-18 Doug Rupp <rupp@gnat.com>
29277 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

29287 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
29288 the procedures Add_To_Path_File.
29289 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
29290 making sure that each directory is present only once and, for object
29291 dirs, when a directory already present is added, the duplicate is
29292 removed and the directory is always put as the last in the table.
29293 Write the path files at the end of these accumulations.
29295 * prj-nmsc.adb (Record_Source): Add source file name in hash table
29296 Files_Htable for all sources.
29298 * prj-proc.adb (Process): Remove restrictions between not directly
29299 related extending projects.

29307 parameter Trusted_Mode.
29309 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
29311 * scn.adb (Determine_License): Take into account a degenerated case
29312 when the source contains only comments.
29314 2004-03-18 Ed Schonberg <schonberg@gnat.com>
29316 * sem_warn.adb (Check_References): For a warning on a selected
29317 component that does not come from source, locate an uninitialized
29318 component of the record type to produce a more precise error message.
29320 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
29322 * 3zsoccon.ads: Fix multicast options.
29324 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
29327 2004-03-15 Robert Dewar <dewar@gnat.com>
29329 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
29330 pragma used for a private type.
29332 * lib-xref.adb (Generate_Reference): Do not generate warning if
29333 reference is in a different unit from the pragma Unreferenced.
29335 * 5vtpopde.adb: Minor reformatting
29336 Fix casing of To_Task_ID
29338 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
29339 flag if we have an unchecked conversion to an access type in the same
29342 2004-03-15 Geert Bosch <bosch@gnat.com>
29344 * a-ngcoty.adb (Modulus): In alternate formula for large real or
29345 imaginary parts, use Double precision throughout.
29347 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
29348 we want to be able to compile run-time with -gnata for testing, but
29349 this may also be instantiated in user code that is compiled with -gnata.
29351 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
29353 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
29354 codes. Having a separate type for this is useful to enforce consistency
29355 throughout the various run-time units.
29356 (Exception_Data): Use Exception_Code for Import_Code.
29358 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
29359 Natural and Integer in various places.

29361 with the severity bits masked off.
29362 (Register_VMS_Exception): Handle the additional exception data pointer

29366 component, now reflected by an exported accessor.
29367 (is_handled_by): New routine to compute whether the propagated
29368 occurrence matches some handler choice specification. Extracted out of
29369 get_action_description_for, and expanded to take care of the VMS
29371 (get_action_description_for): Use is_handled_by instead of an explicit
29372 complex condition to decide if the current choice at hand catches the
29373 propagated occurrence.
29375 * raise.h (Exception_Code): New type for C.
29377 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
29378 System.Standard_Library.Exception_Code, to allow references from the
29379 pragma import/export expander.
29381 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
29382 New accessors to allow easy access to GNAT exception data
29384 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
29385 redundant Handled_By_Others component, helper for the personality
29386 routine which will now be able to call the appropriate exception data
29389 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
29390 component of Standard_Exception_Type to be the closest possible to
29391 Exception_Code in System.Standard_Library, that we cannot get at this
29392 point. Expand a ??? comment to notify that this type node should
29393 probably be rewritten later on.
29395 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
29396 registration call to include a pointer to the exception object in the
29399 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
29400 instead of int and explicit bitmasks.
29402 2004-03-15 Vincent Celier <celier@gnat.com>
29404 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
29405 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
29407 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
29408 longer needed now that it is in the spec of
29409 System.Tasking.Task_Attributes.
29411 * adaint.h, adaint.c: (__gnat_create_output_file): New function
29413 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
29415 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
29417 * make.adb (Gnatmake): Do not check the executable suffix; it is being
29418 taken care of in Scan_Make_Arg.
29419 (Scan_Make_Arg): Add the executable suffix only if the argument
29420 following -o, in canonical case, does not end with the executable
29421 suffix. When in verbose mode and executable file name does not end
29422 with executable suffix, output the executable name, in canonical case.
29424 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
29425 to avoid warnings when instantiating Ada.Task_Attributes.
29428 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
29429 in the correct order.
29431 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

29436 directory, instead of the Value.
29437 (Find_Source_Dirs): Remove useless code & comments.
29439 2004-03-15 Ed Schonberg <schonberg@gnat.com>
29441 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
29442 tagged type is inherited, and the parent operation is not frozen yet,
29443 force generation of a freeze node for the inherited operation, so the
29444 corresponding dispatch entry is properly initialized.
29445 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
29446 when looking for user-defined equality operation.
29448 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
29449 boolean when locating primitive equality of tagged component.
29451 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

29453 a temporary before expanding assignment into a loop.
29455 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
29456 priority in full, to ensure that any expanded subepxressions of it are
29457 elaborated in the scope of the init_proc.
29459 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
29460 after object declaration, skipping over code that may have been
29461 generated for validity checks.
29463 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
29464 discriminants, ignore the known discriminants of its full view, if
29465 any, to check legality.
29467 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
29468 component if type has unknown discriminants.
29469 (Analyze_Private_Extension_Declaration): Discriminant constraint is
29470 null if type has unknown discriminants.
29472 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
29473 for end label when present.
29475 * s-fileio.adb (Open): When called with a C_Stream, use given name for
29476 temporary file, rather than an empty string.
29478 2004-03-15 Ed Falis <falis@gnat.com>
29480 * s-thread.adb: Removed, no longer used.
29482 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

29502 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
29503 Insert_Dereference_Action when rewriting an implicit dereference into
29504 an explicit one, this will be taken care of during expansion of the
29505 explicit dereference.
29506 (Expand_N_Slice): Same. Always do the rewriting, even for the case
29507 of non-packed slices, since the dereference action generated by
29508 expansion of the explicit dereference is needed in any case.
29509 (Expand_N_Selected_Component): When rewriting an implicit dereference,
29510 analyze and resolve the rewritten explicit dereference so it is seen
29512 (Insert_Dereference_Action): This procedure is now called only for the
29513 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
29514 dereferences that do not come from source (including explicit
29515 dereferences resulting from rewriting implicit ones), but do not
29516 recursively insert a check for the dereference nodes contained within
29518 (Insert_Dereference_Action): Clarify and correct comment.

30395 checks for bitfield creation are triggered.
30396 (finish_record_type): During last pass over the fields, clear
30397 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

30737 2004-01-12 Ed Schonberg <schonberg@gnat.com>
30739 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
30740 generated to rename a generic actual, go to the actual itself, the
30741 subtype is not a user-visible entity.
30743 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
30744 part is a private subtype, reset the visibility of its full view, if
30745 any, to be consistent.
30748 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt

30783 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
30784 be modified by the binder generated main program if the -D switch is
30787 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
30788 imported functions (since now we expect this to be done for imported
30791 * 5vtaprop.adb: Add several ??? for sections requiring more comments
30792 Minor reformatting throughout

30800 * sprint.adb: Minor updates to avoid -gnatwa warnings
30802 * s-secsta.ads, s-secsta.adb:
30803 (SS_Get_Max): New function to obtain high water mark for ss stack
30804 Default_Secondary_Stack is not a constant since it may be modified by
30805 the binder generated main program if the -D switch is used.
30807 * switch-b.adb: New -Dnnn switch for binder
30810 Make -gnatg imply all warnings currently in -gnatwa

30841 Acquire new SS indication of secondary stack use from ali files
30843 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
30844 (since now we expect this to be done for imported functions)

30849 * bindusg.adb: Add line for new -D switch
30851 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
30852 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
30853 Add circuitry for both records and arrays to avoid gigi
30854 processing if the type involved has non-bit-aligned components
30856 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
30857 N_String_Literal node always references an E_String_Literal_Subtype
30858 entity. This may not be true in the future.
30859 (Possible_Bit_Aligned_Component): Move processing of
30860 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
30862 * exp_ch6.adb (Expand_Thread_Body): Pick up
30863 Default_Secondary_Stack_Size as variable so that we get value modified
30864 by possible -Dnnn binder parameter.
30866 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
30867 (Type_May_Have_Bit_Aligned_Components): New function.
30869 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

30902 * rtsfind.adb (Load_Fail): Give full error message in configurable
30903 run-time mode if all_errors mode is set. This was not done in the case
30904 of a file not found, which was an oversight.
30905 Note if secondary stack unit is used by compiler.
30907 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
30908 ineffective elaborate all pragmas on non-visible packages (this
30909 happened when a renamed subprogram was called). Now the elaborate all
30910 always goes on the package containing the renaming rather than the one
30911 containing the renamed subprogram.
30913 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
30914 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
30916 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
30917 has an Etype that references an E_String_Literal.
30918 (Eval_String_Literal): Avoid assumption that N_String_Literal node
30919 always references an E_String_Literal_Subtype entity. This may not
30920 be true in the future.

30925 * sem_res.adb (Resolve): Specialize msg for function name used in proc
30928 2004-01-05 Ed Falis <falis@gnat.com>

30936 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
30939 * make.adb (Gnatmake): Special process for files to compile/check when
30940 -B is specified. Fail when there are only foreign mains in attribute
30941 Main of the project file and -B is not specified. Do not skip bind/link
30942 steps when -B is specified.

30967 -gnatwa warning on static condition.
30969 2004-01-05 Doug Rupp <rupp@gnat.com>
30971 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
30973 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
30975 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
30976 all attributes, including read-only attribute.
30978 2004-01-05 Pascal Obry <obry@gnat.com>

30981 library naming scheme.
30983 * mlib-prj.adb (Build_Library): Generate different names for the static
30984 or dynamic version of the GNAT runtime. This is needed to support the
30985 new shared library naming scheme.

30987 based on the new naming scheme.
30989 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
30990 scheme for the shared runtime libraries.
30993 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
30995 (install-gnatlib): Do not create symlinks for shared libraries.
30996 (gnatlib-shared-default): Idem.
30997 (gnatlib-shared-dual-win32): New target. Not used for now as the
30998 auto-import feature does not support arrays/records.
30999 (gnatlib-shared-win32): Do not create copy for the shared libraries.
31000 (gnatlib-shared-vms): Fix shared runtime libraries names.
31002 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
31003 dependent runtime shared library name.
31005 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
31007 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
31010 2004-01-05 Ed Schonberg <schonberg@gnat.com>
31012 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
31013 protected objects when allocator has a subtype indication, not a
31014 qualified expression. Note that qualified expressions may have to be
31015 checked when limited aggregates are implemented.
31017 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
31018 pure, emit warning.
31019 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
31020 subprogram is imported, remove warning.
31022 2004-01-05 Geert Bosch <bosch@gnat.com>
31024 * s-poosiz.adb: Update copyright notice.
31025 (Allocate): Use Task_Lock to protect against concurrent access.

31064 * cstand.adb (Create_Standard): Change the way how the declaration of
31065 the Duration type is created (making it the same way as it is for all
31066 the other standard types).
31068 2003-12-17 Robert Dewar <dewar@gnat.com>

31076 the expression type only if it is declared in the current unit.
31078 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
31079 are universal and already analyzed, as can occur in constrained
31080 subcomponents that depend on discriminants, when one constraint is a
31083 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
31084 type Any_Fixed is legal as the argument of a conversion, if only one

31164 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
31165 Minor reformatting throughout
31167 2003-12-11 Ed Schonberg <schonberg@gnat.com>
31169 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
31170 bounds of a loop, create a separate block in order to generate proper
31171 cleanup actions to prevent memory leaks.
31173 * sem_res.adb (Resolve_Call): After a call to
31174 Establish_Transient_Scope, the call may be rewritten and relocated, in
31175 which case no further processing is needed.
31177 * sem_util.adb: (Wrong_Type): Refine previous fix.
31178 Fixes ACATS regressions.
31181 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
31184 2003-12-08 Jerome Guitton <guitton@act-europe.fr>

31190 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
31193 2003-12-08 Robert Dewar <dewar@gnat.com>
31195 * 7sintman.adb: Minor reformatting
31197 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
31198 standard linker options to get standard libraries linked. We now plan
31199 to provide dummy versions of these libraries to match the appropriate
31200 configurable run-time (e.g. if a library is not needed at all, provide
31201 a dummy empty library).
31203 * targparm.ads: Configurable_Run_Time mode no longer affects linker
31204 options (-L parameters and standard libraries). What we plan to do is
31205 to provide dummy libraries where the libraries are not required.
31207 * gnatbind.adb: Minor comment improvement
31209 2003-12-08 Javier Miranda <miranda@gnat.com>
31211 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
31212 aggregate in the parent. Otherwise constants with limited aggregates
31213 are not supported. Add new formal to pass the component type (Ctype).
31214 It is required to call the corresponding IP subprogram in case of
31215 default initialized components.
31216 (Gen_Assign): In case of default-initialized component, generate a
31217 call to the IP subprogram associated with the component.

31228 improved later). In case of discriminants, this parameter is used to
31229 generate a selected component node that gives access to the discriminant
31232 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New

31632 Adding a check to see whether the Interrupt_ID we want to unmask is in
31633 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
31634 reason is that the index type of the Keep_Unmasked array is not always

33000 Update copyright notice in spec
33002 2003-10-21 Gary Dismukes <dismukes@gnat.com>
33005 (Component_Needs_Simple_Initialization): Return False when the type is a
33006 packed bit array. Revise spec comments to document this case.
33009 (Expand_Pragma_Import): Set any expression on the imported object to
33010 empty to avoid initializing imported objects (in particular this
33011 covers the case of zero-initialization of bit arrays).

35041 (title page): Remove date.
35042 (general) Add @./@: where approriate, and two spaces after the
35043 full stop at the end of a sentence. Use @samp markup when
35044 referring concrete lexical entities (keywords, attribute names
35045 etc.), and @syntax for ARM grammar elements. Use @r for English

35060 * make.adb (Add_Switch): Make Generic_Position a procedure. The
35061 function approach did not work well because of a side effect (the
35062 function call could reallocate the table which was being indexed
35063 using its result). Fixes ada/4851.

35122 Add 2001 to copyright date
35124 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
35125 need to force universal inlining for these cases.

35156 the argument of an initialization procedure.
35158 * trans.c (tree_transform, case of arithmetic operators): If result
35159 type is private, the gnu_type is the base type of the full view,

35248 Compute_Length and Determine_Range.
35249 Above changes fix problem with length computation for supernull arrays
35250 where Max (Len, 0) wasn't getting applied due to the Unsigned
35251 conversion used by Compute_Length.

35341 When using a project file, fail if specified executable is relative
35342 path with directory information, and prepend executable, if not
35343 specified as an absolute path, with the exec directory. Make sure
35344 that only one -o switch is transmitted to the linker.
35346 * prj-attr.adb (Initialization_Data): Add project attribute Exec_Dir

35427 there could be a real problem here with an uninitialized reference
35428 to Hbound, but no actual example of failure has been found.
35430 2001-12-17 Laurent Pautet <pautet@gnat.com>
35433 Fix comment of Shutdown_Socket and Close_Socket. These functions
35434 should not fail silently because if they are called twice, this
35435 probably means that there is a race condition in the user program.
35436 Anyway, this behaviour is consistent with the rest of this unit.
35437 When an error occurs, an exception is raised with the error message
35438 as exception message.
35440 2001-12-17 Robert Dewar <dewar@gnat.com>

36777 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
36778 instead of simple checksum.
36779 (CRC_Match): new function.
36780 (CRC_Error): new constant.
36782 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
36783 a CRC now and not a simple checksum. A CRC uses lower-case hex
36784 letters, fixes ambiguity in parsing.
36786 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
36787 is what this variable will store.

36790 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
36791 rename All_Checksum_Match to All_CRC_Match. Change due to API
36792 renaming since now GNAT does not use a simple checksum but a
36793 CRC using GNAT.CRC32.
36795 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
36796 now and not anymore a simple checksum.

36835 * types.adb (Hex): Use lowercase for the letter part.
36837 * types.ads (Get_Hex_String): Returns the hexadecimal representation
36838 for a word. This is currently used only for CRC. In previous version,
36839 the checksum was using a representation with all letter being
36840 upper-case. With the new implementation (using CRC) we do not remove
36841 the 32th bit of the CRC, so we can have an upper-case starting letter
36842 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
36843 It is ambigous since the CRC was optional and could be followed by
36844 options like EB, EE. So now this routines uses lower-case letter for
36845 the hexadecimal representation. Strange enough only lower case letters
36846 where checked in Scan_ALI (even if this was not a possible case).
36848 * gnatvsn.ads (Library_Version): changed to 3.15a.
36850 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
36853 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
