1964 (Resolve_Attribute, case 'Access): If designated type of context is a
1965 limited view, use non-limited view when available. If the non-limited
1966 view is an unconstrained array, this enforces consistency requirements
1968 (Layout_Type): For an access type whose designated type is a limited
1969 view, examine its declaration to determine if it is an unconstrained
1970 array, and size the access type accordingly.

2166 subprogram body that acts as its own spec may not have a non-private
2167 WITH clause on a private sibling.
2168 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
2169 child unit is a renaming, create an implicit with_clause on that
2170 parent, and not on the unit it renames, to prevent visibility errors

2267 Gary Dismukes <dismukes@adacore.com>
2269 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
2270 requeue statement is dispatching. Do not emit an error when the name is
2271 not an entry and the context is a dispatching select. Add code to
2272 perform subtype conformance between the formals of the current entry
2273 and those of the target interface primitive.
2274 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
2275 Timed_Entry_Call): Analyze the triggering statement as the first step of
2276 the processing. If this is a dispatching select, postpone the analysis
2277 of all select statements until the Expander transforms the select. This
2278 approach avoids generating duplicate identifiers after the Expander has
2279 replicated some of the select statements. In case the Expander is
2280 disabled, perform regular analysis.
2281 (Check_Triggering_Statement): New routine.
2282 (Analyze_Requeue): Exclude any interpretations that are not entries when
2283 checking overloaded names in a requeue. Also test type conformance for
2284 matching interpretations rather than requiring subtype conformance at

2289 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
2290 inherited operation is a defaulted tag-indeterminate call, and there is
2291 a statically tagged actual, use the static tag as a controlling actual
2292 for the defaulted actual.
2294 2007-12-13 Geert Bosch <bosch@adacore.com>
2296 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

2321 latest Ada 2005 rules about renaming and 'Access of
2322 discriminant-dependent components.

2879 multiple inherited interfaces info. This information cannot be stored
2880 in Xref_Entity_Record, which only supports a single instance of Tref_*,

2900 that handles use of 'Access and 'Unchecked_Access applied to

2992 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
2993 association for an access component, add an association with null as
2994 the expression. Remove testing for array subtypes and the setting in
2995 that case of Ctyp to the array component type, which prevented proper
2996 inclusion of an association for null-initialized arrays. Collapse
2997 condition that tests for array subtypes into just a test of
2998 Is_Partially_Initialized_Type (which already covers arrays anyway).

3015 * sem_ch4.adb: Minor code and comment reformatting.
3016 (Analyze_Allocator): When the designated type of an unconstrained
3017 allocator is a record with unknown discriminants or an array with
3018 unknown range bounds, emit a detailed error message depending on the
3019 compilation mode and whether the designated type is limited.

3144 Mapped location support
3145 * back_end.adb (Call_Back_End): Pass information about source
3146 files instead of units to gigi.
3147 * gigi.h (struct File_Info_Type): New.
3148 (gigi): Rename and change type of number_units parameter, change
3149 type of file_info_ptr parameter.
3150 * trans.c (number_files): New global variable.
3151 (gigi): Rename and change type of number_units parameter, change
3152 type of file_info_ptr parameter.
3153 If mapped location support is enabled, create the isomorphic mapping
3154 between source files and line maps.
3155 (Sloc_to_locus): If mapped location support is enabled, translate
3156 source location into mapped location.
3157 (annotate_with_node): Rename into set_expr_location_from_node.

3183 * a-calend-vms.adb, a-calend.adb:
3184 Add a section on leap seconds control along with two entities used to
3185 enable and disable leap seconds support. The array Leap_Second_Times is
3186 now constant and contains hard time values pre-generated. Remove
3187 all elaboration code used to populate the table of leap seconds.
3190 Add entity Leap_Seconds_Support to the list of global run-time variables
3191 along with a comment on its usage and values.
3192 (Gen_Adainit_Ada): Add code to generate the declaration and import of
3193 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
3194 or one (enabled) depending on the presence of binder switch "-y".
3195 (Gen_Adainit_C): Add code to generate the declaration of external int
3196 __gl_leap_seconds_support. Set is value to zero (disabled) or one
3197 (enabled) depending on the presence of binder switch "-y".

3206 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
3207 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
3209 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
3211 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
3212 function which can be called by the debugger to interrupt the tasks of
3213 an Ada application asynchronously, as needed on VxWorks.
3214 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
3216 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
3217 renamed from Stop_All_Tasks. Update comments.

3227 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
3228 #include <sys/wait.h>.
3230 2007-09-26 Thomas Quinot <quinot@adacore.com>
3231 Sergey Rybin <rybin@adacore.com>
3233 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
3235 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
3238 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
3240 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
3243 * sem_dist.ads: Minor comment fix
3245 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
3247 2007-09-26 Javier Miranda <miranda@adacore.com>
3248 Eric Botcazou <ebotcazou@adacore.com>
3251 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
3252 indirection added to the HT_Link component of the TSD. This is required
3253 to statically allocate the TSD.
3256 Minor reordering of the declarations in the private part. Required to
3257 add a level of indirection to the contents of the TSD component HT_Link.
3258 This is required to statically allocate the TSD.
3260 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
3261 Is_Statically_Allocated set from constant objects.
3262 Do not make exported constants created by the compiler volatile.
3263 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
3266 * trans.c (Identifier_to_gnu): For constants, unshare initializers
3267 before returning them.
3269 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
3270 public part of the package.
3271 (Make_DT): Move HT_Link component out of the TSD record. For this
3272 purpose Make_DT now declares a separate object that stores the
3273 HT_Link value, and initializes the TSD component with the address
3274 of this new object. The addition of this level of indirection is
3275 required to statically allocate the TSD because the TSD cannot
3276 have variable components.
3277 (Expand_Interface_Conversion): Improve the expanded code.
3278 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
3280 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
3281 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
3282 if we are building static dispatch tables then we must not generate
3283 extra code to register the primitive because the dispatch table will
3284 be built at the end of the library package; otherwise we notify that
3285 we cannot build the static dispatch table.
3287 2007-09-26 Robert Dewar <dewar@adacore.com>
3289 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
3292 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
3293 (Analyze_Record_Representation_Clause): Suppress junk warning for
3294 missing component clause.

3296 tests for controlled type overlay to composites with controlled
3298 (Analyze_Record_Representation_Clause): Add reference for component name
3300 2007-09-26 Javier Miranda <miranda@adacore.com>
3301 Gary Dismukes <dismukes@adacore.com>

3304 for thunks associated with interface types.
3306 * einfo.ads: Improve documentatation of Is_Internal
3307 (Is_Thunk): New attribute applicable to subprograms. True for thunks
3308 associated with interface types.
3309 Extensive comment fixes regarding flags that appear in all entities. The
3310 documentation is now consistent for all such flags (there were a number
3311 of errors in the documentation in this regard).
3313 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
3315 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
3316 of these procedures are passed a function call that already has
3317 build-in-place actuals (testing new flag
3318 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
3319 the case where processing continues.
3320 (Expand_Call): If the call is generated from a thunk body then we
3321 propagate the extra actuals associated with the accessibility
3322 level of the access type actuals.
3324 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
3325 of each extra formal of a protected operation to reference the
3326 corresponding extra formal of the subprogram denoted by the
3327 operation's Protected_Body_Subprogram.
3329 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
3330 N_Function_Call nodes.
3332 2007-09-26 Robert Dewar <dewar@adacore.com>
3334 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
3336 * debug.adb: Add d.s flag.
3338 2007-09-26 Gary Dismukes <dismukes@adacore.com>
3340 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
3341 debug variable so that it won't be initialized when pragma
3342 Initialize_Scalars is in effect.
3344 2007-09-26 Gary Dismukes <dismukes@adacore.com>
3346 * freeze.adb (Freeze_Entity): Remove check for preelaborable
3347 initialization of a full view. This is moved to
3348 Analyze_Package_Specification.
3350 * sem_ch7.adb (Analyze_Package_Specification): Add check for
3351 preelaborable initialization of a full view in entity loop.
3352 (Uninstall_Declarations): If entity is a use-visible compilation unit,
3353 its child units are use-visible only if they are visible child units.
3355 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
3356 whether an expression can be used within a type declaration that
3357 requires preelaborable init.
3358 (Check_Components): Replace inline code that does partial checking for
3359 preelaborable default expressions with call to
3360 Is_Preelaborable_Expression.
3361 (Has_Preelaborable_Initialization): In the case of a generic actual
3362 subtype, (that is, Is_Generic_Actual is True), return the result of
3363 applying Has_Preelaborable_Initialization to the generic actual's base
3366 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
3368 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
3369 call to Jan_1_Day _Of_Week to optimize its performance.
3370 (Is_Leap): Move the routine to the scope of Week_In_Year.
3371 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
3372 weekday on which January 1 falls of Year - 1 and Year + 1. This function
3373 avoids calling Time_Of and Split, thus making it more efficent.
3374 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
3376 * g-calend.ads (Week_In_Year): Change comment to reflect new
3379 2007-09-26 Emmanuel Briot <briot@adacore.com>
3381 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
3382 Command_Line): New types
3383 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
3384 support for defining how switches can be grouped on a command line (as
3385 is the case for -gnatw... for GNAT), and how simple switches can be
3386 used as aliases for more complex switches (-gnatwa is same as
3388 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
3389 (Start, Current_*): New subprograms
3390 Added support for parsing an array of strings in addition to the real
3392 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
3393 be moved from the body to the private part of the spec.
3394 (*): All subprograms now have an extra parameter with default value to
3395 specify which parser should be used. For backward compatibility, it
3396 defaults to parsing the command line of the application. They were also
3397 modified to properly handle cases where each of the argument does not
3398 start at index 1 (which is always true for Ada.Command_Line, but not
3399 when processing any Argument_List).
3400 (Free): New subprogram
3401 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
3402 Argument): New subprograms
3403 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
3404 special characters like ':', '=',... are now handled in a single place,
3405 which makes the code more extensible eventually.
3406 (Getopt, Full_Switch): When the switch was returned as part of the
3407 special character '*', make sure it is prepended by the switch character
3408 ('-' in general), so that the application knows whether "foo" or "-foo"
3409 was specified on the command line.
3411 2007-09-26 Florian Villoing <villoing@adacore.com>
3413 * g-dirope.adb (Remove_Dir): In case we are removing directories
3414 recursively, make sure that if an exception is raised during the
3415 processing, the current working directory is reset to its initial
3416 value before propagating the exception.
3418 2007-09-26 Vincent Celier <celier@adacore.com>
3420 * gnatbind.adb: If there are several ALI files specified and there is
3421 a main program to bind, the first ALI is expected to contain the main
3422 subprogram and the names of the binder generated files will be derived
3423 from the first ALI file name.
3424 (Gnatbind): Fix insertion character in invocation of Error_Msg
3426 2007-09-26 Vincent Celier <celier@adacore.com>
3428 * gnatcmd.adb (Check_Files): Do not include sources that have been
3429 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
3431 2007-09-26 Ed Schonberg <schonberg@adacore.com>
3433 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
3434 information about each of its index types, following the type
3435 reference for its component type.
3437 2007-09-26 Vincent Celier <celier@adacore.com>
3439 * make.adb: (Kill): New procedure (__gnat_kill imported)
3440 (Running_Compile, Outstanding_Compiles): Global variables that
3441 were previously local to procedure Compile_Sources.
3442 (Sigint_Intercepted): Send signal SIGINT to all outstanding
3443 compilation processes.
3445 (Gnatmake): If project files are used, create the mapping of all the
3446 sources, so that the correct paths will be found.
3448 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
3450 2007-09-26 Vincent Celier <celier@adacore.com>
3452 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
3454 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
3455 Replace components Compiler_Min_Options and Binder_Min_Options with
3456 Compiler_Required_Switches and Binder_Required_Switches in record
3458 Remove components Default_Language and Config in Project_Tree_Data,
3461 * prj-attr.adb: New attributes Required_Switches (<language>) in
3462 packages Compiler and Binder.
3464 * prj-nmsc.adb: Major rewrite of the processing of configuration
3465 attributes for gprbuild. No impact on GNAT tools.
3467 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
3468 process configuration attributes: this is done in Prj.Nmsc.Check.
3469 (Recursive_Process): Make a full copy of packages inherited from project
3470 being extended, instead of a shallow copy.
3471 (Process_Project_Tree_Phase_1): New procedure
3472 (Process_Project_Tree_Phase_1): New procedure
3473 (Process): Implementation now uses the two new procedures
3475 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
3476 from the project config, not the tree config that no longer exists.
3478 2007-09-26 Vincent Celier <celier@adacore.com>

3807 potentially be called.
3808 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
3809 body for 'Output when the type is abstract (only the creation of the
3810 body for 'Input is excluded when the type is abstract).
3811 (Stream_Operation_OK): Add an additional condition in the return
3812 statement, so that False will be returned for TTS_Stream_Input if the
3813 associated tagged type is an abstract extension. Add comments for

3816 variable, insert init proc call only after the shared variable
3817 procedures have been processed, because the IP call needs to undergo
3818 shared passive variable reference expansion, which requires these
3819 procedures to be available (and elaborated).

3835 to remove other spurious ambiguities on arithmetic operations involving
3836 literals and addresses, on systems where Address is a visible integer
3837 type, when the operator is called in functional notation.
3838 (Try_Primitive_Operation): Within an instance, a call in prefixed form
3839 is legal when the types match, even if the operation is currently

3964 (Write_Entity_Flags): Write the status of flag Is_Raised.
3965 (Is_Descendent_Of_Address): New entity flag, to simplify handling of

3987 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
3988 library-level package renaming, pass the declaration associated with
3989 the renaming's special debug variable to Qualify_Entity_Names to ensure
3990 that its encoded name is properly qualified.
3992 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
3993 occurring in the list of entities to qualify, and do not attempt to
3994 traverse an entity list in that case. Variables associated with
3995 ` library-level package renamings can now occur in the table.

4021 avoid very deep recursion in the front end, which was causing stack
4024 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
4025 string, and the right operand is a string literal (the case of "" &
4026 "..."), optimize by avoiding copying the right operand -- just use the
4027 value of the right operand directly.
4029 * stringt.adb (Store_String_Chars): Optimize by growing the
4030 String_Chars table all at once, rather than appending characters one by
4032 (Write_String_Table_Entry): If the string to be printed is very long,
4033 just print the first few characters, followed by the length. Otherwise,
4034 doing "pn(n)" in the debugger can take an extremely long time.
4036 * sem_prag.adb (Process_Interface_Name): Replace loop doing
4037 Store_String_Char with Store_String_Chars.

4056 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
4057 flag, for effiency. It is called when analyzing arithmetic operators
4058 and also for actuals in calls that are universal_integers. The flag is
4059 set for the predefined type address, and for any type or subtype
4062 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
4063 Universal_Integer, when the formal is a descendent of address and the
4064 call appears in user code.

4131 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
4132 associated with Standard_Debug_Renaming_Type, to be used as the type of
4133 the special variables whose names provide debugger encodings for
4134 renaming declarations.
4136 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
4137 (Set_Debug_Renaming_Link): Change to set Node25.

4143 * exp_dbug.adb: Add with and use of Tbuild.
4144 (Debug_Renaming_Declaration): Replace creation of an enumeration type
4145 and literal with creation of a variable of type
4146 Standard_Debug_Renaming_Type whose name encodes both the renamed object
4147 and the entity of the renaming declaration.
4148 (Qualify_Entity_Name): Add the delayed qualification of the entity name
4149 part of the name of a variable that has a Debug_Renaming_Link.

4156 Ed Schonberg <schonberg@adacore.com>
4157 Javier Miranda <miranda@adacore.com>
4159 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
4160 ancestor part given by an aggregate to test for an unchecked conversion,
4161 since this can occur in some cases when the ancestor part is a function
4162 call, and we don't want to fall into the recursive call to this
4163 procedure in that case.
4165 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
4166 stream attributes on limited types to account for user-specified
4167 attributes as well as whether Input (resp. Output) becomes available
4168 due to Read (resp. Write) being available for the type. Change Boolean
4169 variable to the more accurate name
4170 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
4171 double-"not" predicate at beginning of return statement to more
4172 understandable form.
4174 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
4175 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
4176 in a block statement and use that as the first statement of the
4177 expanded return rather than incorrectly using the handled sequence as
4178 the first statement.
4180 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
4181 operation, generate an explicit freeze node for it rather than
4182 generating extra formals, to ensure that gigi has the proper order of
4183 elaboration for anonymous subtypes in the signature of the subprograms.
4184 (Build_In_Place_Formal): Move assertion to beginning of loop.
4185 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
4186 applied to a function call (occurs for some cases of 'Input).
4187 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
4188 applied to a function call (occurs for some cases of 'Input).
4190 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
4191 2005, generate an extended return statement enclosing the result object
4194 * freeze.adb (Freeze_Record_Type): Extend the current management of
4195 components that are access type with an allocator as default value: add
4196 missing support to the use of qualified expressions of the
4197 allocator (which also cause freezing of the designated type!)
4198 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
4199 dispatching operation, since extra formals may be needed by calls to
4200 build-in-place functions (such as stream 'Input).
4202 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
4203 formals for 'Constrained and accessibility level in the case of a
4204 predefined dispatching operation.
4206 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
4207 point, no need to find the parent node.
4209 2007-08-16 Javier Miranda <miranda@adacore.com>
4211 * exp_attr.adb (Attribute_Priority): Add missing support for entries
4214 2007-08-16 Javier Miranda <miranda@adacore.com>
4216 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
4217 is not really required and can introduce regression with the debugger.
4218 The original problem is fixed with the patch written for checks.adb.
4220 2007-08-16 Thomas Quinot <quinot@adacore.com>
4222 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

4228 Including_Non_Switch set to False.
4229 (Gnatmake): For the compiler, call Test_If_Relative_Path with
4230 Including_Non_Switch set to False.
4232 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
4233 parameter Including_Non_Switch, defaulted to True. When
4234 Including_Non_Switch is False, options that are not switches and
4235 appear as relative path are not converted to absolute paths.

4250 from the immediate ancestor of Main_Unit_Entity.
4251 (Install_Limited_Withed_Unit): Do not install the limited view of
4252 package P if P is reachable through an ancestor chain from package C
4253 and C also has a with clause for P in its body.
4254 (Has_Limited_With_Clause): New routine.
4255 (Has_With_Clause): New routine.
4257 2007-08-16 Ed Schonberg <schonberg@adacore.com>
4259 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
4260 generic for an enclosing instance is a global reference, even though
4261 its scope is the enclosing instance.

4264 Javier Miranda <miranda@adacore.com>
4266 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

4284 Bob Duff <duff@adacore.com>
4285 Nicolas Setton <setton@adacore.com>
4287 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
4288 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
4289 the statement which is being resolved comes from a predefined library
4290 unit, all non-predefined library interpretations are skipped.
4291 (Resolve_Op_Concat): If string concatenation was folded in the parser,
4292 but the "&" is user defined, give an error, because the folding would
4295 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
4296 the parser has folded a long sequence of concatenations of string
4299 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
4300 and "JMP_BUF" variables as artificial.
4301 (N_String_Literal): Do not use alloca for very long string literals. Use
4302 xmalloc/free instead. Otherwise the stack might overflow.

4351 This patch is a also fairly significant change to the way suppressible
4354 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
4355 needed for access to concurrent record types generated by the expander.
4356 (Generate_Range_Check): When generating a temporary to capture the
4357 value of a conversion that requires a range check, set the type of the
4358 temporary before rewriting the node, so that the type is always
4359 properly placed for back-end use.
4360 (Apply_Float_Conversion_Check): Handle case where the conversion is
4362 (Get_Discriminal): Code reformatting. Climb the scope stack looking
4363 for a protected type in order to examine its discriminants.

4381 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
4382 aggregate code before allocator, and ahead of declaration for
4383 temporary, to prevent access before elaboration when the allocator is
4384 an actual for an access parameter.
4385 (Expand_N_Type_Conversion): On an access type conversion involving an
4386 access parameter, do not apply an accessibility check when the
4387 operand's original node was an attribute other than 'Access. We now
4388 create access conversions for the expansion of 'Unchecked_Access and
4389 'Unrestricted_Access in certain cases and clearly accessibility should
4390 not be checked for those.
4392 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
4393 includes a type conversion of a packed component that has been expanded,
4394 recover the original expression for the object, and use this expression
4395 in the post-call assignment statement, so that the assignment is made
4396 to the object and not to a back-end temporary.
4397 (Freeze_Subprogram): In case of primitives of tagged types not defined
4398 at the library level force generation of code to register the primitive
4399 in the dispatch table. In addition some code reorganization has been
4400 done to leave the implementation clear.
4401 (Expand_Call): When expanding an inherited implicit conversion,
4402 preserve the type of the inherited function after the intrinsic
4403 operation has been expanded.
4405 * exp_ch2.ads, exp_ch2.adb
4406 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
4407 of an entry formal appearing in an assignment statement does not assign
4409 (Expand_Current_Value): Instead of calling a routine to determine
4410 whether the prefix of an attribute reference should be optimized or
4411 not, prevent the optimization of such prefixes all together.
4413 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
4414 component whose prefix is known to be of an access type is an implicit
4415 dereference and does not assign to the prefix.

4418 Robert Dewar <dewar@adacore.com>
4420 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
4421 itype is visited, make an entry into table to link associated node and
4423 Add comments and correct harmless error in Build_NCT_Hash_Tables

4427 node, to prevent errors when complex expression is copied.
4428 Fix mishandling of multiple levels of parens
4430 * sem_aggr.adb: Create a limited view of an incomplete type, to make
4431 treatment of limited views uniform for all visible declarations in a
4432 limited_withed package.
4433 (New_Copy_Tree): If hash table is being used and itype is visited,
4434 make an entry into table to link associated node and new itype.
4435 (Resolve_Record_Aggregate): Do not add an others box association for a
4436 discriminated record component that has only discriminants, when there
4437 is a box association for the component itself.

4475 Gary Dismukes <dismukes@adacore.com>
4477 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,

4483 (Write_Field26_Name): Handle attribute Related_Interface in constants.
4484 Warn on duplicate pragma Preelaborable_Initialialization
4486 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
4487 generation of a freezing node to ensure proper management of null
4488 excluding access types in the backend.
4489 (Create_Extra_Formals): Test base type of the formal when checking for
4490 the need to add an extra accessibility-level formal. Pass the entity E
4491 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
4492 originally being done in a couple of cases), to ensure that the
4493 Extra_Formals list gets set on the entity E when the first entity is
4495 (Conforming_Types): Add missing calls to Base_Type to the code that
4496 handles anonymous access types. This is required to handle the
4497 general case because Process_Formals builds internal subtype entities
4498 to handle null-excluding access types.
4499 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
4500 functions that need it, even when not marked Requires_Overriding.
4501 Improve warnings for in out parameters
4502 (Analyze_Function_Return): Warn for disallowed null return
4503 Warn on return from procedure with unset out parameter
4504 Ensure consistent use of # in error messages
4505 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
4506 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
4507 the implicit conversion of the expression done for anonymous access
4508 types. This is required to generate the code of the null excluding
4509 check (if required).
4511 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
4512 A formal parameter is never publicly referenceable outside of its body.

4514 statement, use the same warning circuitry as for subprogram formal
4516 (Warn_On_Unreferenced_Entity): New subprogram, taken from
4517 Output_Unreferenced_Messages, containing the part of that routine that
4518 is now reused for entry formals as described above.
4519 (Goto_Spec_Entity): New function
4520 (Check_References): Do not give IN OUT warning for dispatching operation
4521 Improve warnings for in out parameters
4522 (Test_Ref): Check that the entity is not undefinite before calling
4523 Scope_Within, in order to avoid infinite loops.
4524 Warn on return from procedure with unset out parameter
4525 Improved warnings for unused variables

4529 Gary Dismukes <dismukes@adacore.com>
4531 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
4532 (Expand_N_Attribute_Reference): Further unify the handling of the
4533 three forms of access attributes, using common code now for all three
4534 cases. Add a test for the case of applying an access attribute to
4535 an explicit dereference when the context is an access-to-interface
4536 type. In that case we need to apply the conversion to the prefix
4537 of the explicit dereference rather than the prefix of the attribute.
4538 (Attribute_Version, UET_Address): Set entity as internal to ensure
4539 proper dg output of implicit importation.
4540 (Expand_Access_To_Type): Removed.
4541 (Expand_N_Attribute_Reference): Merge the code from the three cases
4542 of access attributes, since the processing is largely identical for
4543 these cases. The substantive fix here is to process the case of a
4544 type name prefix (current instance case) before handling the case
4545 of interface prefixes.

4549 Javier Miranda <miranda@adacore.com>
4550 Robert Dewar <dewar@adacore.com>
4552 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
4553 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
4554 type that is an anonymous access to controlled object, establish
4555 an associated finalization chain to avoid corrupting the global
4556 finalization list when a dynamically allocated object designated
4557 by such a component is deallocated.
4558 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
4559 functions that need it, even when not marked Requires_Overriding.
4560 (Initialize_Tag): Replace call to has_discriminants by call to
4561 Is_Variable_Size_Record in the circuitry that handles the
4562 initialization of secondary tags.

4564 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
4565 Suppress_Initialization pragma for a derived type.
4566 (Is_Variable_Size_Record): New subprogram.
4567 (Build_Offset_To_Top_Functions): New implementation that simplifies the
4568 initial version of this routine and also fixes problems causing
4569 incomplete initialization of the table of interfaces.
4570 (Build_Init_Procedure): Improve the generation of code to initialize the
4571 the tag components of secondary dispatch tables.
4572 (Init_Secondary_Tags): New implementation that simplifies the previous
4573 version of this routine.

4577 diagnose attemps to freeze a subprogram when some untagged type of its
4578 profile is a private type whose full view has not been analyzed yet.
4579 (Freeze_Array_Type): Generate init proc for packed array if either
4580 Initialize or Normalize_Scalars is set.
4581 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
4582 constructing the new profile, copy the null_exclusion indicator for each
4583 parameter, to ensure full conformance of the new body with the spec.
4585 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
4586 Create wrappers for constructor functions that need it, even when not
4587 marked Requires_Overriding.

4600 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
4601 (Write_Overloads): Output the abstract operator if present.
4602 (Add_Entry): Before inserting a new entry into the interpretation table
4603 for a node, determine whether the entry will be disabled by an abstract
4605 (Binary_Op_Interp_May_Be_Hidden): New routine.
4606 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
4608 (Function_Interp_May_Be_Hidden): New routine.
4609 (Has_Compatible_Type): Do not consider interpretations hidden by

4627 output of implicit importation and exportation.
4628 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
4629 first formal of the thunk is always associated with the controlling
4630 type. In addition perform the following code cleanup: remove formal
4631 Thunk_Alias which is no longer required, cleanup evaluation of the
4632 the controlling type, and update the documentation.
4633 Replace occurrence of Default_Prim_Op_Count by
4634 Max_Predef_Prims. Addition of compile-time check to verify
4635 that the value of Max_Predef_Prims is correct.
4636 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
4637 (Make_DT): Add parameter to indicate when type has been frozen by an
4638 object declaration, for diagnostic purposes.

4640 construction of statically allocated dispatch tables.
4641 (Make_DT): In case of library-level tagged types export the declaration
4642 of the primary tag. Remove generation of tags (now done by Make_Tags).
4643 Additional modifications to handle non-static generation of dispatch
4644 tables. Take care of building tables for asynchronous interface types
4645 (Make_Tags): New subprogram that generates the entities associated with
4646 the primary and secondary tags of Typ and fills the contents of Access_
4647 Disp_Table. In case of library-level tagged types imports the forward
4648 declaration of the primary tag that will be declared later by Make_DT.
4649 (Expand_Interface_Conversion): In case of access types to interfaces
4650 replace an itype declaration by an explicit type declaration to avoid
4651 problems associated with the scope of such itype in transient blocks.
4653 2007-08-14 Robert Dewar <dewar@adacore.com>
4654 Ed Schonberg <schonberg@adacore.com>
4655 Javier Miranda <miranda@adacore.com>
4657 * exp_util.ads, exp_util.adb:
4658 This patch replaces a number of occurrences of explicit tests for N_Null
4659 with calls to Known_Null. This improves tracking of null values, since
4660 Known_Null also catches null constants, and variables currently known to
4661 be null, so we get better tracking.
4662 (Ensure_Defined): create an itype reference only in the scope of the
4664 (Side_Effect_Free): A selected component of an access type that
4665 denotes a component with a rep clause must be treated as not
4666 side-effect free, because if it is part of a linked structure its
4667 value may be affected by a renaming.
4668 (Expand_Subtype_From_Expr): For limited objects initialized with build
4669 in place function calls, do nothing; otherwise we prematurely introduce
4670 an N_Reference node in the expression initializing the object, which
4671 breaks the circuitry that detects and adds the additional arguments to
4672 the called function. Bug found working in the new patch for statically
4673 allocated dispatch tables.
4674 (Is_Library_Level_Tagged_Type): New subprogram.
4675 (Remove_Side_Effects): If the expression of an elementary type is an
4676 operator treat as a function call.
4677 (Make_Literal_Range): If the index type of the array is not integer, use
4678 attributes properly to compute the constraint on the resulting aggregate
4681 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
4682 class-wide type whose base type is an incomplete private type, leave
4683 class-wide type unfrozen so that freeze nodes can be generated
4684 properly at a later point.
4685 (Freeze_Entity, array case): Handle case of pragma Pack and component
4686 size attributre clause for same array.

4746 source dirs are not known.
4747 (Check_Ada_Name): Allow all identifiers that are not reserved words
4749 Major update of the Project Manager and of the project aware tools,
4750 including gprmake, so that the same sources in the GNAT repository
4751 can be used by gprbuild.

5360 (Complete_Object_Operation): If actual has an access type and
5361 controlling formal is not an in_parameter, reject the actual if it is
5362 an access_to_constant type.
5363 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
5364 type, the candidate operations are found in the scope of declaration of
5365 the type, because the type has no primitive subprograms.
5366 (Analyze_Selected_Component): If prefix is class-wide, and root type is
5367 a private extension, only examine visible components before trying to
5368 analyze as a prefixed call.
5369 Change Entity_List to Type_To_Use, for better readability.

5382 (Missing_Read_Write_Attributes): A stream attribute is missing for the
5383 purpose of enforcing E.2.2(8) only if it is not available at any place.
5384 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
5385 when checking the legality of an extension aggregate in a preelaborable
5386 package. Treat the literal null as a valid default expression in a
5387 component declaration for a type with preelaborable initialization.
5388 A limited interface is a legal progenitor for the designated type of a
5389 remote access to class-wide type.

5421 do not consider those that are hidden by abstract operators.
5422 (Resolve_Actuals): When verifying that an access to class-wide object
5423 is an actual for a controlling formal, ignore anonymous access to
5424 subprograms whose return type is an access to class_wide type.
5425 (Resolve_Slice): If the prefix of the slice is a selected component
5426 whose type depends on discriminants, build its actual subtype before
5427 applying range checks on the bounds of the slice.

6602 Arnaud Charlet <charlet@adacore.com>
6604 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
6605 applicable to types that have the With_Type flag set. Returns the
6606 non-limited view of the type, if available, otherwise the type itself.

6608 to retrieve the class-wide type of the non-limited view of the Etype.
6609 New attributes Static_Initialization and Static_Elaboration_Desired.
6610 Remove the pragma Thread_Body, and the associated flag

6624 (Original_Access_Type): Remove, not needed.
6625 (Root_Type): Handle properly subtypes of class-wide-types.
6628 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
6629 class-wide types visible through limited-with clauses.
6630 (Try_Primitive_Operation): When examining all primitive operations of a
6631 tagged type, do not consider subprograms labeled as hidden unless they
6632 belong to a private generic type with a tagged parent.
6633 (Try_Object_Operation): Extensive rewriting, to handle properly various
6634 overloading cases, when several ancestors may have class-wide operations
6635 that are possible candidates, and when the overloaded functions return
6636 array types and have defaulted parameters so that the call may be
6637 interpreted as an indexing.
6638 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
6639 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
6640 successive actuals before analyzing the call itself.
6641 (Try_Primitive_Operation): A primitive operation is compatible with the
6642 prefix if the prefix has a synchronized type and the type of the formal
6643 is its corresponding record, as can be the case when the primitive
6644 operation is declared outside of the body of the type.
6645 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
6646 perform homonym traversal, looking for class-wide operation matches
6647 (formerly done in statements of Try_Class_Wide_Operation). Matches on
6648 access parameters are now restricted to anonymous access types.
6649 (Mark_Allocator): An allocator with a discriminant association parent is
6651 (Try_One_Prefix_Interpretation): If the type of the object is
6652 incomplete, as can be happen when it is a limited view obtained through
6653 a limited_with_clause, the selected component is not part of a prefixed
6655 (Complete_Object_Operation): Diagnose properly an object that is not
6656 aliased when the corresponding controlling formal is an access
6658 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
6659 ambiguous calls in prefixed notation, where two primitives differ only
6660 in that the controlling argument of one is an access parameter.
6662 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
6663 whether a function that returns an unconstrained type can be inlined.
6664 (Process_Formals): Diagnose properly the illegal use of an incomplete
6665 type in the profile of an access_to_subprogram declaration.
6666 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
6667 operations are attached to the corresponding record.
6668 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
6669 When processing a primitive of a concurrent type which implements an
6670 interface change the type of all controlling formals to that of the
6671 corresponding record type.
6672 (Check_Synchronized_Overriding): Relax the conditional logic when trying
6673 to determine the tagged type to which a primitive belongs.
6674 (Check_Conventions): Capture condition to ignore a primitive operation
6675 (which is shared between the loop in Check_Conventions and the one in
6676 Check_Convention) in a new local function Skip_Check.
6677 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
6678 confusion with Check_Conventions' own Prim_Op local variable.
6679 (Create_Extra_Formals): Test for a tagged result type rather than a
6680 controlling result when determining whether to add a BIP_Alloc_Form
6681 formal and a BIP_Final_List formal to the function.
6682 (Check_Conformance); For parameters that are anonymous access types,
6683 subtype conformance requires that the not null and the constant
6684 indicators must match
6685 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
6686 to retrieve the appropriate type when processing a concurrent type
6687 declared within a generic. Minor comment reformatting. Change invocation
6688 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
6690 (Analyze_Subprogram_Body): If the return type of a function is an
6691 anonymous access to the limited view of a class-wide type, and the
6692 non-limited view of the type is available, update the type of the
6693 function so that code can be generated.
6694 (Process_Formals): In case of access-subtype itype whose designated
6695 type is also an itype (situation that happens now with access to
6696 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
6697 attribute to avoid backend problems.
6698 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
6699 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
6700 anonymous types' designated types are same before testing
6701 Subtypes_Statically_Match.
6702 (Create_Extra_Formals): Test for a named access parameter that is a
6703 controlling formal as an additional condition for adding an
6704 accessibility level formal. This can occur in the subp type created for
6705 dispatching calls in Expand_Dispatching_Call, and allows calling
6706 Create_Extra_Formals from that procedure rather than special-casing the
6707 extra formals there.
6708 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
6709 when the function has a controlling result.
6710 (Check_Returns): Add much more knowledge of the optimization of local
6711 raise statements to gotos, to retain proper warnings in this case.
6712 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
6713 nodes when looking for last statement.
6715 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
6716 class-wide types visible through limited with clauses.
6717 (Add_One_Interp): If the operands are anonymous access types, the
6718 predefined operator on universal_access is immediately visibles
6719 (Find_Unique_Type): Handle anonymous access to subprogram types just as
6720 other anonymous access types.
6721 (Disambiguate): Take into account CIL convention.
6722 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
6724 2007-06-06 Robert Dewar <dewar@adacore.com>
6726 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
6727 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
6728 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
6729 Fix lower bound of tables.
6732 * nlists.adb: Ditto.
6733 (Prev_Node, Next_Node): Change index type to Int so that it properly
6734 covers the range First_Node_Id - 1 up.
6736 2007-06-06 Javier Miranda <miranda@adacore.com>
6737 Ed Schonberg <schonberg@adacore.com>
6738 Bob Duff <duff@adacore.com>
6739 Hristian Kirtchev <kirtchev@adacore.com>
6741 * exp_aggr.ads, exp_aggr.adb:
6742 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
6743 in extension aggregates.
6744 (Flatten): Other conditions being met, an aggregate is static if the
6745 low bound given by component associations is different from the low
6746 bound of the base index type.
6747 (Packed_Array_Aggregate_Handled): If the component type is itself a
6748 packed array or record, the front-end must expand into assignments.
6749 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
6750 Init_Pr, instead of Ancestor_Is_Expression.
6751 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
6752 coextension chain root, either generate a list controller or use the
6753 already existing one.
6754 (Static_Array_Aggregate): New procedure to construct a positional
6755 aggregate that can be handled by the backend, when all bounds and
6756 components are compile-time known constants.
6757 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
6758 types covering interface types into assignments.
6759 (Replace_Type): move to Build_Record_Aggr_Code.
6760 (Expand_Record_Aggr_Code): if the target of the aggregate is an
6761 interface type, convert to the definite type of the aggregate itself,
6762 so that needed components are visible.
6763 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
6764 components and the context is an extended return statement do not
6765 create a transient block for it, to prevent premature finalization
6766 before the return is executed.
6767 (Gen_Assign): Do not generate a call to deep adjust routine if the
6768 component type is itself an array of controlled (sub)-components
6769 initialized with an inner aggregate.
6770 (Component_Check): New name for Static_Check. This name is now more
6771 appropriate, and documentation is added which was missing.
6772 (Component_Check): Add test for bit aligned component value
6773 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
6774 Tagged_Comps, name is more appropriate given added function below.
6775 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

6778 Javier Miranda <miranda@adacore.com>
6779 Robert Dewar <dewar@adacore.com>
6781 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
6782 Terminated: Add unchecked type conversion from System.Address to
6783 System.Tasking.Task_Id when calling the predefined primitive
6785 Disable new Ada 05 accessibility check for JVM.NET targets, which
6786 cannot be implemented in a practical way.
6787 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
6788 the sources always references the tag of the actual object. Therefore,
6789 if 'Tag is applied in the sources to class-wide interface objects we
6790 generate code that displaces "this" to reference the base of the object.
6791 (Expand_N_Attribute_Reference, case Size): Return specified size if
6793 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
6794 has code that displaces the pointer of the object to manage interface
6795 types. However this code must not be executed when the prefix is a
6796 subprogram. This bug caused the wrong expansion of the internally
6797 generated assignment that fills the dispatch table when the primitive
6798 is a function returning a class-wide interface type.
6799 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
6800 Set_Attribute_Name for Name_Unaligned_Valid.
6802 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6803 Gary Dismukes <dismukes@adacore.com>
6805 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
6806 If the initialization is the equivalent aggregate of the initialization
6807 procedure of the type, do not remove it.
6808 (Expand_N_Attribute_Definition_Clause): Exclude access variables
6809 initialized to null from having their expression reset to empty and
6810 note this exception in the comment.

6813 Robert Dewar <dewar@adacore.com>
6814 Ed Schonberg <schonberg@adacore.com>
6815 Gary Dismukes <dismukes@adacore.com>
6817 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
6818 Add "with" and "use" clauses for Sem_Attr.
6819 (Expand_Current_Value): Do not replace occurences of attribute
6820 references where the prefix must be a simple name.
6822 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
6823 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
6824 Attribute_Requires_Simple_Name_Prefix.
6825 (Name_Modifies_Prefix): Body of new function.
6826 (Requires_Simple_Name_Prefix): Body of new function.
6827 (Resolve_Attribute, case Access): Improve error message for case of
6828 mismatched conventions.
6829 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
6831 (Analyze_Attribute, case 'Access): If the type of the prefix is a
6832 constrained subtype for a nominal unconstrained type, use its base type
6833 to check for conformance with the context.
6834 (Resolve_Attribute): Remove test of the access type being associated
6835 with a return statement from condition for performing accessibility
6836 checks on access attributes, since this case is now captured by
6837 Is_Local_Anonymous_Access.
6838 (Analyze_Access_Attribute): Set Address_Taken on entity
6839 (Analyze_Attribute, case Address): Set Address_Taken on entity
6840 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
6841 validating an access attribute whose prefix is a current instance.
6842 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
6843 applied to dispatching operations, if freezing is required then we set
6844 the attribute Has_Delayed_Freeze in the prefix's entity.
6845 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
6846 current scope if access of local subprogram taken
6847 (Analyze_Access_Attribute): Check legality of self-reference even if the
6848 expression comes from source, as when a single component association in
6849 an aggregate has a box association.
6850 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
6851 the prefix if it is a protected operation and the attribute is
6852 Unrestricted_Access.
6853 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
6854 reference to the base type of the context, to force a constraint check
6855 when the context is an access subtype with an explicit constraint.
6856 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
6857 node is rewritten as an interface conversion. leave unanalyzed after
6858 resolution, to ensure that type checking against the context will take

6862 Javier Miranda <miranda@adacore.com>
6863 Robert Dewar <dewar@adacore.com>
6865 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
6866 wrapper when the full view of the controlling type of an inherited
6867 function that dispatches on result implements interfaces.
6868 (Expand_N_Object_Declaration): In cases where the type of the
6869 declaration is anonymous access, create finalization list for it.
6870 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
6871 if the object has no explicit initialization, to match description of
6872 functionality of pragam Persistent_BSS.
6873 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
6874 new function to build static aggregates, to replace initialization call
6875 when static initialization is desired.
6876 (Freeze_Type): Generate a list controller for an access type whenever
6877 its designated type has controlled anonymous access discriminants.
6878 (Build_Equivalent_Aggregate): New procedure to compute a static
6879 aggregate to be used as default initialization for composite types,
6880 instead of a generating a call to the initialization procedure for the
6882 (Build_Initialization_Call): When available, replace a call to the
6883 initialization procedure with a copy of the equivalent static aggregate
6885 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
6886 declarations for objects of a class-wide interface type, rather than
6887 just identifiers, to prevent visibility problems.
6888 (Expand_N_Object_Declaration): When expanding the declaration for an
6889 object of a class-wide interface type, preserve the homonym chain of
6890 the original entity before exchanging it with that of the generated
6891 renaming declaration.
6892 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
6893 active, because there is no way to handle the exception.
6894 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
6895 to do a minimum decoration of the Access_Disp_Table list.
6896 (Expand_Record_Controller): Avoid the addition of the controller between
6897 the component containing the tag of a secondary dispatch table and its
6898 adjacent component that stores the offset to the base of the object.
6899 This latter component is only generated when the parent type has
6900 discriminants ---documented in Add_Interface_Tag_Components).
6901 (Apply_Array_Size_Check): Removed, no longer needed.
6902 (Expand_N_Full_Type_Declaration): If the type has anonymous access
6903 components, create a Master_Entity for it only if it contains tasks.
6904 (Build_Init_Procedure): Suppress the tag assignment compiling under
6906 (Freeze_Record_Type): Remove code associated with creation of dispatch
6908 (Init_Secondary_Tags): Update type of actuals when generating calls to
6909 Ada.Tags.Set_Offset_To_Top
6910 (Stream_Operation_OK): Disable use of streams compiling under no
6912 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
6913 if Has_Init_Expression set.
6914 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
6915 Register_Primitive, which provides the same functionality.
6916 (Requires_Init_Proc): Return false in case of interface types.
6917 (Add_Secondary_Tables): Use the new attribute Related_Interface to
6919 (Predefined_Primitive_Freeze): Do not assume that an internal entity
6920 is always associated with a predefined primitive because the internal
6921 entities associated with interface types are not predefined primitives.
6922 Therefore, the call to Is_Internal is replaced by a call to the
6923 function Is_Predefined_Dispatching_Operation.
6924 (Make_Eq_If): When generating the list of comparisons for the
6925 components of a given variant, omit the controller component that is
6926 present if the variant has controlled components.
6928 2007-06-06 Javier Miranda <miranda@adacore.com>
6929 Hristian Kirtchev <kirtchev@adacore.com>
6930 Bob Duff <duff@adacore.com>
6932 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
6933 handle the creation of finalization lists and calls for nested
6934 coextensions when the root of the chains is part of a return statement.
6935 (Inside_A_Return_Statement): New function inside Complete_Coextension_
6937 (Expand_Record_Equality): Skip components that are interface types.
6938 (Displace_Allocator_Pointer): Add missing support for interface subtypes
6939 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
6940 with Rewrite_Coextension. Change the condition for detecting coextension
6942 (Is_Local_Access_Discriminant): Removed.
6943 (Rewrite_Coextension): New routine which rewrites a static coextension
6944 as a temporary and uses its unrestricted access in the construction of
6946 (Complete_Coextension_Finalization): New routine. Generate finalization
6947 attachment calls to all delayed coextensions.
6948 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
6949 the allocator is not a coextension itself and has delayed coextensions.
6950 If the current allocator is controlled, but also a coextension, delay
6951 the generation of the finalization attachment call.
6952 Rename local variable "Node" to "Nod" in order to avoid confusion with
6954 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
6955 limited types that are not inherently limited. Such an allocator is
6956 illegal, but is generated by the expander for a return statement, to
6957 copy the result onto the secondary stack. This is the only case where a
6958 limited object can be copied. Generate code to displace the pointer
6959 to the object if the qualified expression is a class-wide interface
6960 object. Such displacement was missing and hence the copy of the object
6962 (Apply_Accessibility_Check): Handle allocated objects initialized in
6964 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
6965 and Expand_Allocator_Expression. Allocating class-wide interface objects
6966 this routine displaces the pointer to the allocated object to reference
6967 the component referencing the corresponding secondary dispatch table.
6968 Expand_Allocator_Expression): Add missing support to allocate class-wide
6969 interface objects initialized with a qualified expression.
6970 (Get_Allocator_Final_List): Test for an anonymous access type that is a
6971 function result type, and use the finalization list associated with the
6972 function scope in that case (such an anonymous type should not be
6973 treated like an access parameter's type).
6975 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6976 Gary Dismukes <dismukes@adacore.com>
6977 Javier Miranda <miranda@adacore.com>
6979 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
6980 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
6981 required exception handler.
6982 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
6983 properly the case of a function whose return type is a limited
6984 class-wide interface type. Modify the code of the accessibility
6985 check to handle class-wide interface objects. In this case we need to
6986 displace "this" to reference the primary dispatch table to get access
6987 to the TSD of the object (to evaluate its accessibility level).
6988 (Expand_N_Extended_Return_Statement): Test for a tagged result type
6989 rather than a controlling result as one of the conditions for
6990 generating tests of the implicit BIP_Alloc_Form formal. The
6991 initialization assignment is also handled according to whether the
6992 result is tagged instead of controlling.
6993 In the case where the init assignment is inserted in the "then" part of
6994 the allocation conditional, rewrite the target to be a dereference of
6995 the implicit BIP_Object_Access formal.
6996 If the returned value is unconstrained and created on the secondary
6997 stack, mark the enclosing block and function so that the secondary
6998 stack is not reclaimed on return.
6999 Treat returns from functions with controlling results similarly to
7000 returns from functions with unconstrained result subtypes.
7001 If the object returned is unconstrained, and an allocator must be
7002 created for it, analyze the allocator once the block for the extended
7003 return is installed, to ensure that finalizable components
7004 of the expression use the proper finalization list. Guard the call to
7005 Move_Final_List with a check that there is something to finalize.
7006 (Make_Tag_Ctrl_Assignment): Use "old" handling
7007 of controlled type assignment for virtual machines, since new code uses
7008 unsupported features (such as direct access to bytes in memory).
7010 2007-06-06 Gary Dismukes <dismukes@adacore.com>
7011 Ed Schonberg <schonberg@adacore.com>
7013 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
7014 accessibility actual, check for the case of an aliased object that has
7015 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
7016 we fall into processing for the attribute rather than the name of the
7018 (Expand_Inline_Call): If an actual is a literal, and the corresponding
7019 formal has its address taken in the body, create a temporary to capture
7020 value. If the return type is a limited interface, do not treat the
7021 return value as Controlled.
7022 (Is_In_Place_Function): If the return type is a limited interface,
7023 treat as returning in place. The actual returned object may not always
7024 be limited, but the caller has to assume that it is returned in place.
7025 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
7026 context of an allocator, use the correct finalization chain (that is,
7027 the chain belonging to the access type, rather than the chain belonging
7028 to the current scope).
7029 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
7030 result type rather than a controlling result as a precondition for
7031 adding an allocation form actual to a build-in-place call.
7032 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
7033 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
7034 primitive in the dispatch tables. This work is now done by Make_DT when
7036 (Register_Predefined_DT_Entry): Removed.
7037 (Add_Return): If end label is not present, use sloc of last statement
7038 for generated return statement in procedure, for better gdb behavior
7040 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
7041 object address nodes to ensure proper processing by routines like
7043 (Expand_Call): Fix generation of validity check for parameter
7044 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
7045 the allocation form parameter if the result subtype is constrained,
7046 except when the function has a controlling result.
7047 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
7048 rather than Is_Controlled and Has_Controlled_Component, since we want to
7049 include class-wide result types in this treatment. Also test for a
7050 controlling result, since that also requires passing a finalization
7052 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
7053 even when the result subtype is constrained, to handle calls involving
7054 controlling results.
7055 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
7056 is now called even when the result subtype is constrained, to handle
7057 calls involving controlling results.
7058 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
7059 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
7060 now performs the test).
7061 (Make_Build_In_Place_Call_In_Object_Declaration):
7062 Add_Alloc_Form_Actual_* is now called even when the result subtype is
7063 constrained, to handle calls involving controlling results.
7064 (Add_Return): Accomodate rewritten pattern from local raise to goto
7065 transformation, so that we still recognize an transfer statement
7066 and do the right thing here in that case.
7067 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
7068 and end of subprogram code.
7069 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
7070 support for primitives that are functions (without formals) with a
7072 (Inherited_From_Formal): If the actual subtype has not generic parent
7073 type, it is not an actual for a formal derived type, and there is no
7074 operation to inherit from the formal.
7076 2007-06-06 Ed Schonberg <schonberg@adacore.com>
7077 Thomas Quinot <quinot@adacore.com>
7079 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
7080 inserted cleanup code appropriately for GDB use.
7081 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
7082 exception handler for Deep_Adjust or Deep_Finalize.
7083 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
7084 Raise_From_Controlled_Operation is available, use a call to that
7085 subprogram instead of a plain "raise Program_Error" node to raise
7086 Program_Error if an exception is propagated from an Adjust or Finalize
7088 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
7089 appears in the optional statement list of a triggering alternative, the
7090 scope actions can be inserted directly there, and not in the list that
7091 includes the asynchronous select itself.
7093 2007-06-06 Ed Schonberg <schonberg@adacore.com>
7094 Robert Dewar <dewar@adacore.com>
7095 Hristian Kirtchev <kirtchev@adacore.com>
7097 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
7098 generated exception handler appropriately when debugging generated code.
7099 Deal properly with No_Exception_Propagation restriction mode.
7100 (Expand_N_Abort_Statement): Add an unchecked type conversion from
7101 System.Address to System.Tasking.Task_Id when processing the result of
7102 the predefined primitive _disp_get_task_id.
7103 (Expand_N_Asynchronous_Select): Clarify comment.
7104 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
7105 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
7106 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
7107 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
7108 privals and for generated call to Complete_Entry_Body, for better gdb
7110 (Copy_Result_Type): Utility to construct a parameter and result profile
7111 for protected functions whose return type is an anonymous access to
7113 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
7115 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
7116 point when the local-raise-to-goto transformation has taken place.
7118 2007-06-06 Javier Miranda <miranda@adacore.com>
7119 Nicolas Setton <setton@adacore.com>
7121 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
7122 functionality when the backend is generating code.
7123 Otherwise any serious error
7124 reported by the backend calling the frontend routine Error_Msg
7125 changes the Compilation_Mode to Check_Semantics, disables the
7126 functionality of this routine and causes the generation of
7127 spureous additional errors.
7129 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
7130 debugging information now generated by the compiler for fat-pointer
7132 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
7134 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
7136 2007-06-06 Thomas Quinot <quinot@adacore.com>
7138 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
7139 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
7140 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
7141 For a remote call to a function with a classwide return type, apply an
7142 E.4(18) check to the returned value.
7143 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
7144 stream attributes of the designated type of an RACW, as they are not
7145 dispatching primitive operations.
7147 2007-06-06 Geert Bosch <bosch@adacore.com>
7149 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a

7267 subtype from the function call, as is done for private types.
7268 (Side_Effect_Free): An expression that is the renaming of an object or

9135 for all access attributes, because overload resolution should work the
9136 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
9137 causes the error message for the ambiguous "X'Access = Y'Access" and
9138 "X'Unrestricted_Access = Y'Access" and so forth to match.
9139 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,

9237 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
9238 when -gnatg is not specified.

9290 parameter of the containing subprogram.
9291 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
9292 under No_Dispatching_Calls restriction. During the semantic analysis
9293 we already notified such violation.

9312 Modify the declaration of the object containing the TSD
9313 because we now expand code that has a higher level of abstraction.
9314 The TSD has a discriminant containing the Inheritance Depth Level,
9315 value that is used in the membership test but also to fix the size
9316 of the table of ancestors.

9476 * Retrieve the extra formals parameters at the
9477 end of the parameter stream.

9500 typecode from the Etype. Therefore we retrieve the correct typecode
9501 with a call to Get_Any_Type.
9502 (Copy_Specification): Do controlling formal type substitution based on
9503 Is_Controlling_Formal flag, instead of caller-provided object type.
9504 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
9505 a RACW primitive operation, we might get a subprogram declaration for an
9506 ancestor of the RACW designated type (not for the designated type
9507 itself), in the case where this operation is inherited. In this case we
9508 have no easy means of determining the original tagged type for which
9509 the primitive was declared, so instead we now rely on
9510 Copy_Specification to use the Is_Controlling_Formal flag to determine
9511 which formals require type substitution.

9516 * exp_intr.adb (Expand_Exception_Call): Calls to subprograms in
9517 GNAT.Current_Exception are not allowed if pragma Restrictions
9518 (No_Exception_Propagation) is set and in any case make the associated
9519 handler unsuitable as a target for a local raise statement.
9520 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
9521 run-time subprogram CW_Membership by call to Build_CW_Membership.
9522 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
9523 by a function call, a temporary must be created before expanding the
9524 Constructor_Call itself, to prevent out-of-order elaboration in the
9525 back-end when stack checking is enabled..

9973 unit, in which case the instance must be analyzed with the latest Ada
9974 mode. This setting must take place after analysis of the actuals,
9975 because the actuals must be analyzed and frozen in the Ada mode extant

9996 non-limited view is available, use the non-limited one.
9997 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
9998 therefore illegal), suggest a qualified expression rather than a type
9999 conversion, because a type conversion would be illegal in this context.
10000 (Anayze_Allocator): Trace recursively all nested allocators so that all
10001 coextensions are on the corresponding list for the root. Do no mark
10002 coextensions if the root allocator is within a declaration for a stack-
10003 allocated object, because the access discriminants will be allocated on
10005 (Analyze_Call): Remove restriction on calls to limited functions for the
10006 cases of generic actuals for formal objects, defaults for formal objects
10007 and defaults for record components.
10008 (Analyze_Allocator): Before analysis, chain coextensions on the proper
10009 element list. Their expansion is delayed until the enclosing allocator
10010 is processed and its finalization list constructed.
10011 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
10012 for an operation with the given name among the primitive operations of
10013 the corresponding record type.
10014 (Analyze_Selected_Component): If the prefix is a task type that
10015 implements an interface, and there is no entry with the given name,
10016 check whether there is another primitive operation (e.g. a function)
10018 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
10019 properly the indexing of a function call written in prefix form, where
10020 the function returns an array type, and all parameters of the function
10021 except the first have defaults.
10022 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
10023 the original operands, rather than relocating them, for efficiency and
10024 to work properly when an operand is overloaded.
10025 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
10026 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
10027 (Analyze_Selected_Component): If the prefix is a private extension, only
10028 scan the visible components, not those of the full view.
10029 (Try_Primitive_Operation): If the operation is a procedure, collect all
10030 possible interpretations, as for a function, because in the presence of
10031 classwide parameters several primitive operations of the type can match
10032 the given arguments.

10045 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
10046 out of Analyze_Package_Declaration, because processing must be applied
10047 to package bodies as well, for deferred constants completed by pragmas.
10048 (Analyze_Package_Declaration): When the package declaration being
10049 analyzed does not require an explicit body, call Check_Completion.
10050 (May_Need_Implicit_Body): An implicit body is required when a package
10051 spec contains the declaration of a remote access-to-classwide type.
10052 (Analyze_Package_Body): If the package contains RACWs, append the
10053 pending subprogram bodies generated by exp_dist at the end of the body.
10054 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
10055 Is_Abstract_Subprogram and Is_Abstract_Type.
10056 (Preserve_Full_Attributes): The full entity list is not an attribute
10057 that must be preserved from full to partial view.
10059 * sem_dist.adb (Add_RAS_Dereference_TSS):
10060 Change primitive name to _Call so it cannot clash with any legal
10061 identifier, and be special-cased in Check_Completion.
10062 Mark the full view of the designated type for the RACW associated with
10063 a RAS as Comes_From_Source to get proper view switching when installing
10064 private declarations.
10065 Provite a placeholder nested package body along with the nested spec
10066 to have a place for Append_RACW_Bodies to generate the calling stubs
10067 and stream attributes.
10069 2007-04-06 Ed Schonberg <schonberg@adacore.com>
10070 Robert Dewar <dewar@adacore.com>

10078 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
10079 renaming as body when renamed entity is abstract.

10094 Javier Miranda <miranda@adacore.com>
10096 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
10097 dereference of a local object R created as a reference to another
10098 object O, use the access level of O.
10099 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
10100 rather than local Same_Formal_Type, to check whether protected operation
10101 overrides an inherited one.
10102 (Same_Formal_Type): New predicate, used when matching signatures of
10103 overriding synchronized operations, to handle the case when a formal
10104 has a type that is a generic actual.
10105 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
10106 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
10107 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
10108 syntactic ambiguities involving indexing of function calls that return
10110 (Abstract_Interface_List): New subprogram that returns the list of
10111 abstract interfaces associated with a concurrent type or a
10112 concurrent record type.
10113 (Interface_Present_In_Parent): New subprogram used to check if a
10114 given type or some of its parents implement a given interface.
10115 (Collect_Abstract_Interfaces): Add support for concurrent types
10116 with interface types.
10117 (Has_Abstract_Interfaces): Add support for concurrent types with
10119 (Is_Parent): New subprogram that determines whether E1 is a parent
10120 of E2. For a concurrent type its parent is the first element of its
10121 list of interface types; for other types this function provides the
10122 same result than Is_Ancestor.
10123 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
10124 (Collect_Synchronized_Interfaces): Removed because the subprogram
10125 Collect_Abstract_Interfaces provides this functionality.
10126 (Collect_Abstract_Interfaces): Minor update to give support to
10127 concurrent types and thus avoid undesired code duplication.
10128 (Get_Subprogram_Entity): Handle entry calls.
10129 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
10131 (Enter_Name): Do not give -gnatwh hiding warning for record component

10147 can be an E_Return_Statement.
10148 (Is_Coextension): New flag for allocators.

10167 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
10168 expression with a COMPOUND_EXPR including the call instead of emitting
10169 the call directly here.
10170 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
10171 high bound is constant and the slice is empty. Tidy.
10172 (tree_transform, case N_Op_Not): Handle properly the case where the
10173 operation applies to a private type whose full view is a modular type.
10174 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
10175 Address_Clause, use the associated Expression as the GNAT tree
10176 representing the choice value to ensure the corresponding GCC tree is
10177 of the proper kind.
10178 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
10179 instead of just the operands, as the base GCC stabilize_reference does.
10180 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
10181 requested; otherwise fail.
10182 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

10187 implementation of UI_Div.
10188 (UI_Div): Reimplement as a call to UI_Div_Rem.
10189 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
10190 remainder, avoiding the cost of a multiplication and a subtraction.

10192 provides both quotient and remainder in a single computation.
10193 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
10194 functions for uint.
10195 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

10438 (Resolve_Arithmetic_Op): Do not give an error on calls to the
10439 universal_fixed "*" and "/" operators when they are used in a context
10440 that expects any real type. Also set the type of the node to

10442 (mainly static expression evaluation).
10443 Reword some continuation messages
10444 Add some \\ sequences to continuation messages
10445 (Resolve_Call): Refine infinite recursion case. The test has been

10932 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
10933 mechargs instead of sigargs, as the latter can be retrieved from the

10981 (Set_All_DT_Position): Hidden entities associated with abstract
10982 interface primitives are not taken into account in the check for

10995 (Make_DT): If the ancestor of the type is a CPP_Class and we are
10996 compiling under full ABI compatibility mode we avoid the generation of

10998 this mode we currently inherit the dispatch tables in the IP subprogram.
10999 (Write_DT): Emit an "is null" indication for a null procedure primitive.
11000 (Expand_Interface_Conversion): Use an address as the type of the formal

11053 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
11054 assignments where the target subtype is unconstrained and the target
11055 object is a parameter or dereference (other aliased cases are known

11173 (Replace_Self_Reference): New subsidiary of
11174 Make_OK_Assignment_Statement, to replace an access attribute that is a
11175 self-reference into an access to the appropriate component of the

11177 nested at any level.
11178 (Is_Self_Referential_Init): Remove, not needed.

11190 that has been derived from several abstract interfaces we must also

11219 subcomponent's enclosing variable is aliased with a constrained subtype.
11220 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
11221 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
11222 an aliased prefix must be known to be constrained in order to use True
11223 for the attribute value, and now it's possible for some aliased views
11224 to be unconstrained.

11243 required to report the correct error message.
11244 (Expand_N_Subtype_Indication): Do validity checks on range
11245 (Clean_Task_Names): If an initialization procedure includes a call to

11255 Object_Declaration to the call.
11256 (Freeze_Type): When the designated type of an RACW was not frozen at the
11257 point where the RACW was declared, validate the primitive operations
11258 with respect to E.2.2(14) when it finally is frozen.
11259 (Build_Initialization_Call,Expand_Record_Controller): Rename
11260 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
11261 return-by-reference has no meaning in Ada 2005.
11262 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
11263 to register tag of the immediate ancestor interfaces in the
11264 run-time structure.

11266 initialization of extension aggregates with abstract interfaces.
11267 (Build_Master_Renaming): Make public, for use by function declarations
11268 whose return type is an anonymous access type.
11269 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
11270 Insert_List_Before_And_Analyze after the generation of the specs
11271 associated with null procedures.

11273 (Init_Secondary_Tags): Update documentation.
11274 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
11275 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
11276 then generate code to inherit the contents of the dispatch table
11277 directly from the ancestor.
11278 (Expand_Record_Controller): Insert controller component after tags of
11279 implemented interfaces.

11285 (Is_Null_Interface_Procedure): New function in
11286 Make_Null_Procedure_Specs.
11287 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
11288 immediate ancestor of a tagged type is an abstract interface type we
11289 must generate the specification of the predefined primitives associated
11290 with controlled types (because the dispatch table of the ancestor is
11291 null and hence these entries cannot be inherited). This is required to
11292 elaborate well the dispatch table.

11306 the maximum for type T.
11307 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
11308 when the allocator is initialized by a build-in-place call, since the
11309 allocator is already rewritten as a reference to the function result,
11310 and this prevents an unwanted duplication of the function call.
11311 Add with and use of Exp_Ch6.
11312 (Expand_Allocator_Expresssion): Check for an allocator whose expression
11313 is a call to build-in-place function and apply
11314 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and

11321 discriminants of anonymous access types (AI-402, AI-416)
11323 2006-10-31 Bob Duff <duff@adacore.com>
11324 Robert Dewar <dewar@adacore.com>
11325 Gary Dismukes <dismukes@adacore.com>
11326 Ed Schonberg <schonberg@adacore.com>
11328 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
11330 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
11331 (Expand_N_Assignment_Statement): Call
11332 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
11333 build-in-place function call. Currently, this can happen only for
11334 assignments that come from aggregates.
11335 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11336 in order to alleviate the upward compatibility introduced by AI-318.
11337 (Expand_N_Extended_Return_Statement): Add support for handling the
11338 return object as a build-in-place result.
11339 (Expand_Non_Function_Return): Implement simple return statements nested
11340 within an extended return.
11341 (Enable_New_Return_Processing): Turn on the new processing of return
11343 (Expand_Non_Function_Return): For a return within an extended return,
11344 don't raise Program_Error, because Sem_Ch6 now gives a warning.
11345 (Expand_N_Extended_Return_Statement): Implement AI-318
11346 (Expand_Simple_Function_Return): Ditto.
11347 (Expand_N_If_Statement): Handle new -gnatwt warning
11348 (Expand_N_Case_Statement): Handle new -gnatwt warning
11349 (Expand_N_Assignment): Handle assignment to the Priority attribute of
11350 a protected object.
11351 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
11352 validity checking of assignments to elementary record components.
11353 (Expand_N_Return_Statement): return Class Wide types on the secondary
11354 stack independantly of their controlled status since with HIE runtimes,
11355 class wide types are not potentially controlled anymore.
11357 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
11360 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
11361 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
11362 it expects a block, procedure, or task. The return statement will get
11363 turned into a block, and Expand_Cleanup_Actions will happen then.
11365 2006-10-31 Robert Dewar <dewar@adacore.com>
11366 Ed Schonberg <schonberg@adacore.com>
11367 Bob Duff <duff@adacore.com>
11368 Gary Dismukes <dismukes@adacore.com>
11370 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
11372 (Expand_Inlined_Call): Tagged types are by-reference types, and
11373 therefore should be replaced by a renaming declaration in the expanded
11374 body, as is done for limited types.
11375 (Expand_Call): If this is a call to a function with dispatching access
11376 result, propagate tag from context.
11377 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
11379 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
11380 build-in-place when the right-hand side of an assignment is a
11381 build-in-place function call.
11382 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
11383 of the explicit dereference of the allocator to the result subtype of
11384 the build-in-place function. This is needed to satisfy type checking
11385 in cases where the caller's return object is created by an allocator for
11386 a class-wide access type and the type named in the allocator is a
11388 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
11389 conversion of the reference to the declared object to the result subtype
11390 of the build-in-place function. This is needed to satisfy type checking
11391 in cases where the declared object has a class-wide type. Also, in the
11392 class-wide case, change the type of the object entity to the specific
11393 result subtype of the function, to avoid passing a class-wide object
11394 without explicit initialization to the back end.
11395 (Register_Interface_DT_Entry): Moved outside the body of
11396 Freeze_Subprogram because this routine is now public; it is called from
11397 Check_Dispatching_Overriding to handle late overriding of abstract
11398 interface primitives.
11399 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
11400 adding an implicit access actual on a call to a build-in-place function.
11401 (Expand_Actuals): Test for an actual parameter that is a call to a
11402 build-in-place function and apply
11403 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
11404 (Is_Build_In_Place_Function): New function to determine whether an
11405 entity is a function whose calls should be handled as build-in-place.
11406 (Is_Build_In_Place_Function_Call): New function to determine whether an
11407 expression is a function call that should handled as build-in-place.
11408 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
11409 calls to build-in-place functions as the initialization of an allocator.
11410 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
11411 handling calls to build-in-place functions in contexts that do not
11412 involve init of a separate object (for example, actuals of subprogram
11414 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
11415 handling calls to build-in-place functions as the initialization of an
11416 object declaration.
11417 (Detect_Infinite_Recursion): Add explicit parameter Process to
11418 instantiation of Traverse_Body to avoid unreferenced warning.
11419 (Check_Overriding_Inherited_Interfaces): Removed.
11420 (Register_Interface_DT_Entry): Code cleanup.
11421 (Register_Predefined_DT_Entry): Code cleanup.
11422 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
11423 inlined statements if within a transient scope.
11424 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
11425 formal parameters with occurrences of actuals in inlined body, establish
11426 visibility on the proper view of the actual's subtype for the body's
11428 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
11429 compatibility mode and we have an imported CPP subprogram because
11430 for now we assume that imported CPP primitives correspond with
11431 objects whose constructor is in the CPP side (and therefore we
11432 don't need to generate code to register them in the dispatch table).
11433 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
11434 aligned selected component.
11435 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
11436 the actual of an in-mode parameter is a type conversion.
11437 (Expand_Actuals): If the call does not come from source and the actual
11438 is potentially misaligned, let gigi handle it rather than rejecting the
11439 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
11440 Class Wide types as returning by reference independantly of their
11441 controlled status since with HIE runtimes class wide types are not
11442 potentially controlled anymore.
11444 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11446 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
11447 references that are private components of the protected object.
11448 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
11449 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
11450 instantiation to deal with warnings.
11451 (Initialize_Protection): If expression for priority is non-static, use
11452 System_Priority as its expected type, in case the expression has not
11455 2006-10-31 Robert Dewar <dewar@adacore.com>
11457 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
11458 initialization of Homonym_Len.
11459 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
11460 names from fully qualified name. Fixes problem of duplicate
11461 external names differing only in the presence of such a block name.
11463 2006-10-31 Thomas Quinot <quinot@adacore.com>
11464 Pablo Oliveira <oliveira@adacore.com>
11466 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
11467 subprogram Ids, even if they are not yet assigned.
11468 (Build_Subprogram_Id): It is now this function that will take care of
11469 calling Assign_Subprogram_Ids if necessary.
11470 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
11471 should be done only once they are assigned.
11472 (Build_From_Any_Function, case of tagged types): Add missing call to
11474 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
11475 type for an RACW type.
11476 (Add_RACW_Features): When processing an RACW declaration for which the
11477 designated type is already frozen, enforce E.2.2(14) rules immediately.
11478 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
11479 special reordering of controlling formals.
11481 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
11482 associated stub type for an RACW type.
11484 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11486 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
11487 fixed-point operations in an integer context, i.e. as operands of a
11488 conversion to an integer type, indicate that result must be rounded.
11490 2006-10-31 Robert Dewar <dewar@adacore.com>
11492 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
11493 cases, pass the encoding method, since it is now required by the run
11496 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
11497 assumption that Str'First = 1.
11498 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
11499 it on to the Value_Wide_Wide_Character call.
11500 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
11501 properly handles a string of the form quote-encoded_wide_char-quote.
11503 * s-wchcnv.adb: Minor reformatting
11505 2006-10-31 Javier Miranda <miranda@adacore.com>
11507 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
11508 run-time membership test to ensure that the constructed object
11509 implements the target abstract interface.
11511 2006-10-31 Robert Dewar <dewar@adacore.com>
11513 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
11514 Machine_Attribute pragma internally to implement the user pragma.
11515 Add processing for pragma Interface so that it is now completely
11516 equivalent to pragma Import.
11518 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
11519 so that it can be applied to all entities, including record components
11520 and enumeration literals.
11521 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
11522 priority ranges are correct, verify compatibility against task
11523 dispatching and locking policies, and if everything is correct an entry
11524 is added to the table containing priority specific dispatching entries
11525 for this compilation unit.
11526 (Delay_Config_Pragma_Analyze): Delay processing
11527 Priority_Specific_Dispatching pragmas because when processing the
11528 pragma we need to access run-time data, such as the range of
11529 System.Any_Priority.
11530 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
11531 Allow pragma Unreferenced as a context item
11532 Add pragma Preelaborable_Initialization
11533 (Analyze_Pragma, case Interface): Interface is extended so that it is
11534 now syntactically and semantically equivalent to Import.
11535 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
11536 insertion characters.
11537 Add handling for Pragma_Wide_Character_Encoding
11538 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
11539 never supercedes a real restriction, and that a real restriction
11540 always supercedes a warning.
11541 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
11544 2006-10-31 Bob Duff <duff@adacore.com>
11545 Ed Schonberg <schonberg@adacore.com>
11546 Robert Dewar <dewar@adacore.com>
11548 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
11549 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
11550 Is_Inherently_Limited_Type, because return-by-reference has no meaning
11552 (Find_Node_To_Be_Wrapped): Use new method of determining the result
11553 type of the function containing a return statement, because the
11554 Return_Type field was removed. We now use the Return_Applies_To field.
11556 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
11557 (Build_Task_Image_Decl): If procedure is not called from an
11558 initialization procedure, indicate that function that builds task name
11559 uses the sec. stack. Otherwise the enclosing initialization procedure
11560 will carry the indication.
11561 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
11562 N_Object_Declaration instead.
11563 (Kill_Dead_Code): New interface to implement -gnatwt warning for
11564 conditional dead code killed, and change implementation accordingly.
11565 (Insert_Actions): Add N_Return_Object_Declaration case.
11566 Correct comment to mention N_Extension_Aggregate node.
11567 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
11568 attempts to save information for global variables which cannot be
11570 (Get_Current_Value_Condition): Handle conditions the other way round
11571 (constant on left). Also handle right operand of AND and AND THEN
11572 (Set_Current_Value_Condition): Corresponding changes
11573 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
11574 (Get_Current_Value_Condition): Handle simple boolean operands
11575 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
11576 (Get_Current_Value_Condition): If the variable reference is within an
11577 if-statement, does not appear in the list of then_statments, and does
11578 not come from source, treat it as being at unknown location.
11579 (Get_Current_Value_Condition): Enhance to allow while statements to be
11580 processed as well as if statements.
11581 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
11583 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
11584 of loop. This is safe now that we fixed Kill_Current_Values.
11585 (OK_To_Do_Constant_Replacement): Check whether current scope is
11586 Standard, before examining outer scopes.
11588 2006-10-31 Vincent Celier <celier@adacore.com>
11590 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
11591 When True, apply VMS treatment to children of packages A, G, I and S.
11594 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
11596 2006-10-31 Robert Dewar <dewar@adacore.com>
11597 Ed Schonberg <schonberg@adacore.com>
11599 * freeze.adb: Add handling of Last_Assignment field
11600 (Warn_Overlay): Supply missing continuation marks in error msgs
11601 (Freeze_Entity): Add check for Preelaborable_Initialization
11603 * g-comlin.adb: Add Warnings (Off) to prevent new warning
11605 * g-expect.adb: Add Warnings (Off) to prevent new warning
11607 * lib-xref.adb: Add handling of Last_Assignment field
11608 (Generate_Reference): Centralize handling of pragma Obsolescent here
11609 (Generate_Reference): Accept an implicit reference generated for a
11610 default in an instance.
11611 (Generate_Reference): Accept a reference for a node that is not in the
11612 main unit, if it is the generic body corresponding to an subprogram
11615 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
11617 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
11619 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
11621 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
11622 use clauses, to avoid messages on packages used to qualify, and also
11623 to avoid messages from obsolescent units.
11624 (Warn_On_Useless_Assignments): Don't generate messages for imported
11625 and exported variables.
11626 (Warn_On_Useless_Assignments): New procedure
11627 (Output_Obsolescent_Entity_Warnings): New procedure
11628 (Check_Code_Statement): New procedure
11630 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
11631 Change name Is_Ada_2005 to Is_Ada_2005_Only
11632 (Last_Assignment): New field for useless assignment warning
11634 2006-10-31 Olivier Hainque <hainque@adacore.com>
11636 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
11637 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
11639 2006-10-31 Bob Duff <duff@adacore.com>
11640 Robert Dewar <dewar@adacore.com>
11641 Ed Schonberg <schonberg@adacore.com>
11643 * g-awk.adb (Default_Session, Current_Session): Compile this file in
11644 Ada 95 mode, because it violates the new rules for AI-318.
11646 * g-awk.ads: Use overloaded subprograms in every case where we used to
11647 have a default of Current_Session. This makes the code closer to be
11648 correct for both Ada 95 and 2005.
11650 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
11651 code, relying on the fact that the compiler generates a warning
11652 instead of an error in -gnatg mode.
11654 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
11655 E_Return_Statement entity kind.
11656 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
11658 * par.adb (P_Interface_Type_Definition): Addition of one formal to
11659 report an error if the reserved word abstract has been previously found.
11660 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
11662 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
11663 parenthesized range attribute usage
11664 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
11666 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
11667 in the syntax for extended_return_statement. This is not in the latest
11668 RM, but the ARG is expected to issue an AI allowing this.
11669 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
11670 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
11671 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
11672 P_Return_Statement): Parse the new syntax for extended_return_statement.
11674 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
11675 Output_End_Missing): Add error-recovery code for the new
11676 extended_return_statement syntax; that is, the new E_Return entry on
11679 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
11680 limited to nonlimited, because otherwise we violate the new Ada 2005
11681 rules about returning limited types in function Create_AST_Handler in
11684 * sem.adb (Analyze): Add cases for new node kinds
11685 N_Extended_Return_Statement and N_Return_Object_Declaration.
11687 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
11688 type is in the same category as type of context before applying check,
11689 to prevent anomalies in instantiations.
11690 (Resolve_Aggregate): Remove test for limited components in aggregates.
11691 It's unnecessary in Ada 95, because if it has limited components, then
11692 it must be limited. It's wrong in Ada 2005, because limited aggregates
11694 (Resolve_Record_Aggregate): Move check for limited types later, because
11695 OK_For_Limited_Init requires its argument to have been resolved.
11696 (Get_Value): When copying the component default expression for a
11697 defaulted association in an aggregate, use the sloc of the aggregate
11698 and not that of the original expression, to prevent spurious
11699 elaboration errors, when the expression includes function calls.
11700 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
11701 were missing. We also didn't handle qualified expressions. Now also
11702 allow function calls. Use new common routine OK_For_Limited_Init.
11703 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
11704 with space can upper case letter).
11706 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
11707 Has_Static_Discriminants flag
11708 (Record_Type_Declaration): Diagnose an attempt to declare an interface
11709 type with discriminants.
11710 (Process_Range_Expr_In_Decl): Do validity checks on range
11711 (Build_Discriminant_Constraints): Use updated form of
11712 Denotes_Discriminant.
11713 (Process_Subtype): If the subtype is a private subtype whose full view
11714 is a concurrent subtype, introduce an itype reference to prevent scope
11716 (Build_Derived_Record_Type, Collect_Interface_Primitives,
11717 Record_Type_Declaration): The functionality of the subprograms
11718 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
11719 is now performed by a single routine.
11720 (Build_Derived_Record_Type): If the type definition includes an explicit
11721 indication of limitedness, then the type must be marked as limited here
11722 to ensure that any access discriminants will not be treated as having
11723 a local anonymous access type.
11724 (Check_Abstract_Overriding): Issue a detailed error message when an
11725 abstract subprogram was not overridden due to incorrect mode of its
11727 (Analyze_Private_Extension_Declaration): Add support for the analysis of
11728 synchronized private extension declarations. Verify that the ancestor is
11729 a limited or synchronized interface or in the generic case, the ancestor
11730 is a tagged limited type or synchronized interface and all progenitors
11731 are either limited or synchronized interfaces.
11732 Derived_Type_Declaration): Check for presence of private extension when
11733 dealing with synchronized formal derived types.
11734 Process_Full_View): Enchance the check done on the usage of "limited" by
11735 testing whether the private view is synchronized.
11736 Verify that a synchronized private view is completed by a protected or
11738 (OK_For_Limited_Init_In_05): New function.
11739 (Analyze_Object_Declaration): Move check for limited types later,
11740 because OK_For_Limited_Init requires its argument to have been resolved.
11741 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11742 in order to alleviate the upward compatibility introduced by AI-318.
11743 (Constrain_Corresponding_Record): If the constraint is for a component
11744 subtype, mark the itype as frozen, to avoid out-of-scope references to
11745 discriminants in the back-end.
11746 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
11747 this subprogram against wrong sources.
11748 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
11749 discriminant of limited type completed with a protected type, when the
11750 discriminant is used to constrain a private component of the type, and
11751 expansion is disabled.
11752 (Find_Type_Of_Object): Do not treat a return subtype that is an
11753 anonymous subtype as a local_anonymous_type, because its accessibility
11754 level is the return type of the enclosing function.
11755 (Check_Initialization): In -gnatg mode, turn the error "cannot
11756 initialize entities of limited type" into a warning.
11757 (OK_For_Limited_Init): Return true for generated nodes, since it
11758 sometimes violates the legality rules.
11759 (Make_Incomplete_Declaration): If the type for which an incomplete

11761 preserve the homonym chain when removing it from visibility.
11762 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
11763 inherited subprograms.
11764 (Access_Definition): If this is an access to function that is the return
11765 type of an access_to_function definition, context is a type declaration
11766 and the scope of the anonymous type is the current one.
11767 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
11768 incomplete subtype to the set of private dependents of the original
11770 (Constrain_Discriminated_Type): Emit an error message whenever an
11771 incomplete subtype is being constrained.

11812 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
11813 call it with -static-libgcc, as there are some platforms, such as
11814 Darwin, where one of these two switches is compulsory to link.
11816 2006-10-31 Vincent Celier <celier@adacore.com>
11818 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
11819 instead of ADA_PROJECT_PATH, for the project path.
11820 (Gnatls): When displaying the project path directories, use host dir
11823 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
11824 names in the project path, as absolute paths may correspond to
11825 multi-valued VMS logical names.

11858 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
11860 (Layout_Variant_Record): Retrieve the discriminants from the entity
11861 rather than from the type definition, because in the case of a full
11862 type for a private type we need to take the discriminants from the
11864 (Layout_Component_List): When applying the Max operator to variants with
11865 a nonstatic size, check whether either operand is static and scale that
11866 operand from bits to storage units before applying Max.
11867 (Layout_Type): In VMS, if a C-convention access type has no explicit
11868 size clause (and does not inherit one in the case of a derived type),
11869 then the size is reset to 32 from 64.
11871 2006-10-31 Vincent Celier <celier@adacore.com>
11873 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
11874 its file has already been loaded, according to the unit being loaded,
11875 not to the current value of Multiple_Unit_Index.

11913 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11915 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
11916 Process_Body_Clauses): If the context of a body includes a use clause
11917 for P.Q then a with_clause for P in the same body is not redundant,
11918 even if the spec also has a with_clause on P.
11919 Add missing continuation mark to error msg
11920 (Build_Limited_Views): A limited view of a type is tagged if its
11921 declaration includes a record extension.
11922 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
11923 node, even if the subunit has errors. This avoids malfunction by
11924 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
11925 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
11926 generation of obsolescent messages for with statements (cannot do
11927 this too early, or we cannot implement avoiding the messages in the
11928 case of obsolescent units withing obsolescent units).
11929 (Install_Siblings): If the with_clause is on a remote descendant of
11930 an ancestor of the current compilation unit, find whether there is
11931 a sibling child unit that is immediately visible.
11932 (Remove_Private_With_Clauses): New procedure, invoked after completing
11933 the analysis of the private part of a nested package, to remove from
11934 visibility the private with_clauses of the enclosing package
11936 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
11937 now centralized in Generate_Reference.
11938 (Install_Limited_Context_Clauses): Remove superfluous error
11939 message associated with unlimited view visible through use
11940 and renamings. In addition, at the point in which the error
11941 is reported, we add the backslash to the text of the error
11942 to ensure that it is reported as a single error message.
11943 Use new // insertion for some continuation messages
11944 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
11945 to create implicit with_clause for parent unit mentioned in original
11946 limited_with_clause.
11947 (Install_Limited_With_Unit): Set entity of parent identifiers if the
11948 unit is a child unit. For ASIS queries.
11949 (Analyze_Subunit): If the subunit appears within a child unit, make all
11950 ancestor child units directly visible again.

11965 a formal object declaration with an access definition or a subtype mark
11966 with a null exclusion.
11967 (P_Generic_Association): Handle association with box, and others_choice
11968 with box, to support Ada 2005 partially parametrized formal packages.
11970 2006-10-31 Robert Dewar <dewar@adacore.com>
11971 Javier Miranda <miranda@adacore.com>
11973 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
11974 (P_Type_Declaration): Remove barrier against the reserved word "limited"
11975 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
11976 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
11977 private extensions.
11978 (P_Type_Declaration): Add the new actual Abstract_Present to every call
11979 to P_Interface_Type_Definition.
11980 (P_Interface_Type_Definition): Addition of one formal to report an error
11981 if the reserved word abstract has been previously found.
11982 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
11983 object renaming declaration with an access definition or subtype mark
11984 with a possible null exclusion.

12003 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
12006 2006-10-31 Vincent Celier <celier@adacore.com>
12008 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
12009 on VMS, change "__" to '.' before checking the name.
12010 (Record_Ada_Source): Always add the source file name in the list of
12011 of sources, even if it is not the first time, as it is for another
12013 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
12014 dot, instead of replacing only the first '_'.
12016 * prj-part.adb (Parse): Convert project file path to canonical form
12018 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
12019 extended, the project id of the project extending it is recorded in its
12020 data, even when it has already been processed as an imported project.
12022 2006-10-31 Robert Dewar <dewar@adacore.com>
12024 * repinfo.adb (List_Entities): Don't list entities from renaming
12027 2006-10-31 Arnaud Charlet <charlet@adacore.com>
12028 Robert Dewar <dewar@adacore.com>
12030 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
12031 only a restriction warning is active for the given restriction. This is
12032 desirable because we do not want to modify code in the case where only
12034 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
12035 causes overriding of real restrictions.
12036 Take advantage of new No_Restrictions constant.
12038 * raise.h: (__gnat_set_globals): Change profile.
12040 2006-10-31 Arnaud Charlet <charlet@adacore.com>
12042 * rtsfind.adb: Remove s-polint from comment as it exists no more.
12045 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
12046 Move all the entities in obsolete package System.PolyORB_Interface to
12047 System.Partition_Interface.

12062 Javier Miranda <miranda@adacore.com>
12063 Gary Dismukes <dismukes@adacore.com>
12065 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
12066 properly an attempt to apply Unchecked_Access to a protected operation.
12067 (OK_Self_Reference): New subprogram to check the legality of an access
12068 attribute whose prefix is the type of an enclosing aggregate.
12069 Generalizes previous mechanism to handle attribute references nested
12070 arbitrarily deep within the aggregate.
12071 (Analyze_Access_Attribute): An access attribute whose prefix is a type
12072 can appear in an aggregate if this is a default-initialized aggregate
12073 for a self-referential type.
12074 (Resolve_Attribute, case Access): Ditto.
12075 Add support for new implementation defined attribute Stub_Type.
12076 (Eval_Attribute, case Attribute_Stub_Type): New case.
12077 (Analyze_Attribute, case Attribute_Stub_Type): New case.
12078 (Stream_Attribute_Available): Implement using new subprogram from
12079 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
12080 Has_Specified_Stream_Attribute flag.
12081 Disallow Storage_Size and Storage_Pool for access to subprogram
12082 (Resolve_Attribute, case 'Access et al): Take into account anonymous
12083 access types of return subtypes in extended return statements. Remove
12084 accessibility checks on anonymous access types when Unchecked_Access is
12086 (Analyze_Attribute): Add support for the use of 'Class to convert
12087 a class-wide interface to a tagged type.
12088 Add support for the attribute Priority.
12089 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
12090 whether the designated type is discriminated with a constrained partial
12091 view and require static matching in that case.
12092 Add local variable Des_Btyp. The Designated_Type
12093 of an access to incomplete subtype is either its non-limited view if
12094 coming from a limited with or its etype if regular incomplete subtype.
12096 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
12097 Fix predicate to identify and allow cases of (expander-generated)
12098 references to tag of designated object of a RACW.
12099 (Validate_Static_Object_Name): In Ada 2005, a formal object is
12100 non-static, and therefore cannot appear as a primary in a preelaborable
12102 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
12103 Has_Read_Write_Attributes.
12104 (Has_Read_Write_Attributes): Reimplement in termes of
12105 Has_Stream_Attribute_Definition.
12106 (Missing_Read_Write_Attributes): When checking component types in a
12107 record, unconditionally call Missing_Read_Write_Attributes recursively
12108 (remove guard checking for Is_Record_Type / Is_Access_Type).
12110 2006-10-31 Robert Dewar <dewar@adacore.com>
12112 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
12113 useless assignments here and conditionalize it on absence of exception
12115 (Analyze_Exception_Handlers): Small code reorganization of error
12116 detection code, for new handling of formal packages.
12118 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12119 Hristian Kirtchev <kirtchev@adacore.com>
12121 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
12122 that has been constant-folded, preserve information of original tree,
12124 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
12125 generated private extension declaration if the formal derived type is
12126 synchronized. Carry synchronized present over to the generated private
12128 (Validate_Derived_Type_Instance): Ensure that the actual of a
12129 synchronized formal derived type is a synchronized tagged type.
12130 (Instantiate_Formal_Package): When creating the instantiation used to
12131 validate the actual package of a formal declared without a box, check
12132 whether the formal itself depends on a prior actual.
12133 (Instantiate_Formal_Subprogram): Create new entities for the defining
12134 identifiers of the formals in the renaming declaration, for ASIS use.
12135 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
12136 a renaming declaration or a subtype declaration for an actual in an
12137 instance, capture location information of declaration in generic, for
12139 (Instantiate_Formal_Package): Add comments on needed additional tests.
12140 AI-317 (partial parametrization) is fully implemented.
12141 (Validate_Private_Type_Instance): Add check for actual which
12142 must have preelaborable initialization
12143 Use new // insertion for some continuation messages
12144 (Analyze_Formal_Object_Declaration): Change usage of Expression to
12145 Default_Expression. Add type retrieval when the declaration has an
12146 access definition. Update premature usage of incomplete type check.
12147 (Check_Access_Definition): New subsidiary routine. Check whether the
12148 current compilation version is Ada 05 and the supplied node has an
12150 (Instantiate object): Alphabetize local variables. Handle the creation
12151 of new renaming declarations with respect to the kind of definition
12152 used - either an access definition or a subtype mark. Guard against
12153 unnecessary error message in the context of anonymous access types after
12154 they have been resolved. Add check for required null exclusion in a
12155 formal object declaration.
12156 (Switch_View): A private subtype of a non-private type needs to be
12157 switched (the base type can have been switched without its private
12158 dependents because of the last branch of Check_Private_View.
12159 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
12161 (Instantiate_Type): Emit an error message whenever a class-wide type of
12162 a tagged incomplete type is used as a generic actual.
12163 (Find_Actual_Type): Extend routine to handle a component type in a child
12164 unit that is imported from a formal package in a parent.
12165 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
12166 agree on constrainedness, rather than checking against ultimate ancestor
12167 (Instantiate_Subprogram_Body): Create a cross-reference link to the
12168 generic body, for navigation purposes.
12170 2006-10-31 Robert Dewar <dewar@adacore.com>
12171 Thomas Quinot <quinot@adacore.com>
12173 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
12175 (New_Stream_Subprogram): When processing an attribute definition clause
12176 for a stream-oriented subprogram, record an entity node occurring at
12177 the point of clause to use for checking the visibility of the clause,
12178 as defined by 8.3(23) as amended by AI-195.
12179 (New_Stream_Subprogram): New procedure, factoring behaviour from both
12180 New_Stream_Function and New_Stream_Procedure.
12181 (New_Stream_Function, New_Stream_Procedure): Removed.
12182 (Analyze_Attribute_Definition_Clause, case Address): Check new
12183 Alignment_Check check
12185 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12186 Javier Miranda <miranda@adacore.com>
12187 Robert Dewar <dewar@adacore.com>
12189 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
12190 generate the same errors compiling under -gnatc.
12191 (Try_Object_Operation): If no candidate interpretation succeeds, but
12192 there is at least one primitive operation with the right name, report
12193 error in call rather than on a malformed selected component.
12194 (Analyze_Selected_Component): If the prefix is an incomplete type from
12195 a limited view, and the full view is available, use the full view to
12196 determine whether this is a prefixed call to a primitive operation.
12197 (Operator_Check): Verify that a candidate interpretation is a binary
12198 operation before checking the type of its second formal.
12199 (Analyze_Call): Add additional warnings for function call contexts not
12201 (Analyze_Allocator): Move the check for "initialization not allowed for
12202 limited types" after analyzing the expression. This is necessary,
12203 because OK_For_Limited_Init looks at the structure of the expression.
12204 Before analysis, we don't necessarily know what sort of expression it
12205 is. For example, we don't know whether F(X) is a function call or an
12206 indexed component; the former is legal in Ada 2005; the latter is not.
12207 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
12208 were missing. We also didn't handle qualified expressions. Now also
12209 allow function calls. Use new common routine OK_For_Limited_Init.
12210 (Analyze_Type_Conversion): Do not perform some legality checks in an
12211 instance, because the error message will be redundant or spurious.
12212 (Analyze_Overloaded_Selected_Component): Do not do style check when
12213 setting an entity, since we do not know it is the right entity yet.
12214 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
12215 (Analyze_Overloaded_Selected_Component): Same change
12216 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
12217 since regular incomplete subtypes are transformed into corresponding
12218 subtypes of their full views.
12219 (Complete_Object_Operation): Treat name of transformed subprogram call
12220 as coming from source, for browsing purposes.
12221 (Try_Primitive_Operation): If formal is an access parameter, compare
12222 with base type of object to determine whether it is a primitive
12224 (Operator_Check): If no interpretation of the operator matches, check
12225 whether a use clause on any candidate might make the operation legal.

12235 Add \\ to some continuation messages
12236 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
12237 (Process_Bounds): If the bounds are integer literals that result from
12238 constant-folding, and they carry a user-defined type, preserve that type
12239 rather than treating this as an integer range.
12240 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
12241 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
12242 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
12243 left hand side of assignment.

12247 not just identifiers.
12248 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
12249 or AND THEN for possible tracking.
12250 (Analyze_Iteration_Scheme): Check for setting Current_Value for the

12254 Hristian Kirtchev <kirtchev@adacore.com>
12255 Bob Duff <duff@adacore.com>
12257 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
12258 procedure cannot be a protected operation (it is a basic_declaration,
12259 not a subprogram_declaration).
12260 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
12261 Subp. Add logic for entry processing.
12262 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.

12276 pass new parameters. Add support for adding the new extra access formal
12277 for functions whose calls are treated as build-in-place.
12278 (Analyze_A_Return_Statement): Correct casing in error message.
12279 Move Pop_Scope to after Analyze_Function_Return, because an extended
12280 return statement really is a full-fledged scope. Otherwise, visibility
12281 doesn't work right. Correct use of "\" for continuation messages.
12282 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
12283 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
12284 the node doesn't get properly marked as analyzed.
12285 (Analyze_Subprogram_Body): If subprogram is a function that returns
12286 an anonymous access type that denotes a task, build a Master Entity
12288 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
12289 proper usage of null exclusion in a result definition.

12298 homonym chain if it corresponds with an abstract interface primitive.
12299 (Process_Formals): Replace membership test agains Incomplete_Kind with a
12300 call to the synthesized predicate Is_Incomplete_Type.

12303 (Analyze_Subprogram_Declaration): Check that abstract interface
12304 primitives are abstract or null.
12305 (Analyze_Subprogram_Specification): Remove previous check for abstract
12306 interfaces because it was not complete.
12307 (Has_Interface_Formals): Removed.

12312 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
12313 of Analyze_Package_Body, to create Itype references for anonymous
12314 access types created in the package declaration, whose designated types
12315 may have only a limited view.
12316 (Analyze_Package_Specification): For the private part of a nested
12317 package, install private_with_clauses of enclosing compilation unit if
12318 we are in its visible part.
12319 (Declare_Inherited_Private_Subprograms): Complete barrier
12320 to ensure that the primitive operation has an alias to some parent
12321 primitive. This is now required because, after the changes done for the
12322 implementation of abstract interfaces, the contents of the list of
12323 primitives has entities whose alias attribute references entities of
12324 such list of primitives.
12325 (Analyze_Package_Specification): Simplify code that handles parent units
12326 of instances and formal packages.
12327 (Uninstall_Declarations): Check the convention consistency among
12328 primitive overriding operations of a tagged record type.

12342 as potentially use-visible.
12343 (Find_Type): Handle the case of an attribute reference for
12344 implementation defined attribute Stub_Type (simply let the analysis of
12345 the attribute reference rewrite it).

12347 type that appears in a Use_Type clause.
12348 (Analyze_Object_Renaming): Add support for renaming of the Priority
12350 (Find_Type): In Ada 2005, a task type can be used within its own body,
12351 when it appears in an access definition.
12352 (Analyze_Object_Renaming): Remove warning on null_exclusion.
12353 (Analyze_Object_Renaming): Introduce checks for required null exclusion
12354 in a formal object declaration or in a subtype declaration.
12355 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
12356 (Check_Null_Exclusion): New local routine to
12357 Analyze_Subprogram_Renaming. Check whether the formals and return
12358 profile of a renamed subprogram have required null exclusions when
12359 their counterparts of the renaming already impose them.
12360 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
12361 Determine whether an entity is inside a generic scope.
12362 (In_Open_Scope): First pass of documentation update.
12363 (Find_Expanded_Name): Add support for shadow entities associated with
12364 limited withed packages. This is required to handle nested packages.
12365 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
12366 that makes a renaming of a limited withed package illegal.

12369 Ed Schonberg <schonberg@adacore.com>
12371 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
12372 Check_Overriding_Indicator.
12373 (Analyze_Task_Definition): Ditto.
12374 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
12375 (Check_Overriding_Indicator): To find overridden interface operation,
12376 examine only homonyms that have an explicit subprogram declaration, not
12377 inherited operations created by an unrelated type derivation.
12378 (Check_Overriding_Indicator): When checking for the presence of "null"
12379 in a procedure, ensure that the queried node is a procedure

12382 type when the formal is an access to variable.
12383 (Analyze_Protected_Type): Add check for Preelaborable_Initialization

12397 of a call to a function that dispatches on access result.
12398 (Check_Dispatching_Operation): In case of late overriding of a primitive
12399 that covers abstract interface subprograms we register it in all the
12400 secondary dispatch tables associated with abstract interfaces.
12401 (Check_Dispatching_Call): Add check that a dispatching call is not made
12402 to a function with a controlling result of a limited type. This is a
12403 current implementation restriction.
12404 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
12405 (Check_Dispatching_Operation): Do no emit a warning if the controlling
12406 argument is an interface type that is a generic formal.
12407 (Is_Interface_Subprogram): Removed.
12408 (Check_Dispatching_Operation): If the subprogram is not a dispatching
12409 operation, check the formals to handle the case in which it is
12410 associated with an abstract interface type.

12428 Javier Miranda <miranda@adacore.com>
12430 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve

12432 (Covers): Handle coverage of formal and actual anonymous access types in
12433 the context of generic instantiation.
12434 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
12435 abstract interface types; this is required to handle concurrent types
12436 with discriminants and abstract interface types.

12452 qualification from an expression. There are numerous places where this
12453 ought to be used, but we currently only deal properly with zero or one
12455 (In_Instance); The analysis of the actuals in the instantiation of a
12456 child unit is not within an instantiation, even though the parent
12457 instance is on the scope stack.

12460 (Check_Obsolescent): Removed
12461 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

12479 (Has_Compatible_Alignment): New function
12480 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
12481 objects to handle the Ada 2005 case, where aliasedness no longer implies

12537 (Return_Object_Declarations): New field to support extended return
12539 (N_Extended_Return_Statement): New node for extended_return_statement
12541 (N_Return_Object_Declaration): New node for part of

12715 * a-rttiev.ads, a-rttiev.adb:
12716 This is a significant redesign primarily for the sake of automatic
12717 timer task termination but also to fix a design flaw.
12718 Therefore we are now using an RTS lock, instead of a protected
12719 object, to provide mutual exclusion to the queue of pending events
12720 and the type Timing_Event is no longer a protected type.

13226 we must pass the work to the expander to generate the required code to
13227 evaluate the conversion at run-time.
13228 (Resolve_Equality_Op): Do not apply previous
13229 transformation if expansion is disasbled, to prevent anomalies when

13902 save/restore routines.
13903 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

13905 Since we are changing the tree format anyway, also get rid of the
13906 junk obsolete Immediate_Errors flag.
13907 (Tree_Read): Change the way of reading Tree_Version_String - now we

13998 (Freeze_Record_Type): Do not generate the tables associated with
13999 timed and conditional dispatching calls through synchronized
14000 interfaces if compiling under No_Dispatching_Calls restriction.
14001 When compiling for Ada 2005, for a nonabstract
14002 type with a null extension, call Make_Controlling_Function_Wrappers
14003 and insert the wrapper function declarations and bodies (the latter
14004 being appended as freeze actions).
14005 (Predefined_Primitive_Bodies): Do not generate the bodies of the
14006 predefined primitives associated with timed and conditional
14007 dispatching calls through synchronized interfaces if we are
14008 compiling under No_Dispatching_Calls.

14010 service is available before generating a call.
14011 (Make_Controlling_Function_Wrappers): New procedure.
14012 (Expand_N_Full_Type_Declaration): Create a class-wide master for

14014 tasks that implement such limited interface.
14015 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
14016 procedure spec and body of the Offset_To_Top function that is generated
14017 when the parent of a type with discriminants has secondary dispatch
14019 (Init_Secondary_Tags): Handle the case in which the parent of the type
14020 containing secondary dispatch tables has discriminants to generate the
14021 correct arguments to call Set_Offset_To_Top.
14022 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
14024 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
14025 Add Wide_[Wide_]Expanded_Name.
14026 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
14027 the same functionality of Get_Prim_Op_Address but applied to predefined
14028 primitive operations because the pointers to the predefined primitives
14029 are now saved in a separate table.
14030 (Parent_Size): Modified to get access to the separate table of primitive
14031 operations or the parent type.
14032 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
14033 functionality of Set_Prim_Op_Address but applied to predefined primitive
14035 (Set_Signature): New subprogram used to store the signature of a DT.
14036 (Displace): If the Offset_To_Top value is not static then call the
14037 function generated by the expander to get such value; otherwise use
14038 the value stored in the table of interfaces.
14039 (Offset_To_Top): The type of the actual has been changed to Address to
14040 give the correct support to tagged types with discriminants. In this
14041 case this value is stored just immediately after the tag field.
14042 (Set_Offset_To_Top): Two new formals have been added to indicate if the
14043 offset_to_top value is static and hence pass this value to the run-time
14044 to store it in the table of interfaces, or else if this value is dynamic
14045 and then pass to the run-time the address of a function that is
14046 generated by the expander to provide this value for each object of the
14049 * rtsfind.ads (Default_Prin_Op_Count): Removed.
14050 (Default_Prim_Op_Count): New entity

14061 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
14062 in a subprogram are wrapped in a cleanup block, indicate that the
14063 subprogram contains an inner block with an exception handler.
14064 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
14065 Adjust call is for a newly-allocated object. In that case we must not
14066 assume that the finalization list chain pointers are correct (since they
14067 come from a bit-for-bit copy of the original object's pointers) so if
14068 the attach level would otherwise be zero (no change), we set it to 4
14069 instead to cause the pointers to be reset to null.
14071 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
14072 reset chain pointers to null.
14074 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14076 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
14077 string, and the context requires a loop for the assignment (e.g.
14078 because the left-hand side is packed), generate a unique name for the
14079 temporary that holds the string, to prevent spurious name clashes.

14084 Gary Dismukes <dismukes@adacore.com>
14086 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
14087 return unconstrained arrays.
14089 (Expand_Call): An indirect call through an access parameter of a
14090 protected operation is not a protected call.
14091 Add circuit to raise CE in Ada 2005 mode following call
14092 to Raise_Exception.
14093 (Register_DT_Entry): Do nothing if
14094 the run-time does not give support to abstract interfaces.
14095 (Freeze_Subprogram): In case of dispatching operations, do not generate
14096 code to register the operation in the dispatch table if the source
14097 is compiled with No_Dispatching_Calls.
14098 (Register_Predefined_DT_Entry): Generate code that calls the new
14099 run-time subprogram Set_Predefined_Prim_Op_Address instead of
14100 Set_Prim_Op_Address.
14102 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
14103 on array assignments if the right-hand side is a function call that has
14104 been inlined. Check is performed on the assignment in the block.
14105 (Process_Bounds): If bounds and range are overloaded, apply preference
14106 rule for root operations to disambiguate, and diagnose true ambiguity.
14107 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
14108 a tag-indeterminate right-hand side even when Expander_Active is True.
14109 Needed to ensure that dispatching calls to T'Input are allowed and
14110 get the tag of the target class-wide object.
14112 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
14113 an inherited primitive operation that already overrides several
14114 abstract interface primitives. For transitivity, the new entity must
14115 also override all the abstract interface primitives covered by the
14116 inherited overriden primitive.
14117 Emit warning if new entity differs from homograph in same scope only in
14118 that one has an access parameter and the other one has a parameter of
14119 a general access type with the same designated type, at the same
14120 position in the signature.
14121 (Make_Inequality_Operator): Use source locations of parameters and
14122 subtype marks from corresponding equality operator when creating the
14123 tree structure for the implicit declaration of "/=". This does not
14124 change anything in behaviour except that the decoration of the
14125 components of the subtree created for "/=" allows ASIS to get the
14126 string images of the corresponding identifiers.
14127 (Analyze_Return_Statement): Remove '!' in warning message.
14128 (Check_Statement_Sequence): Likewise.
14129 (Analyze_Subprogram_Body): For an access parameter whose designated type
14130 is an incomplete type imported through a limited_with clause, use the
14131 type of the corresponding formal in the body.
14132 (Check_Returns): Implicit return in No_Return procedure now raises
14133 Program_Error with a compile time warning, instead of beging illegal.
14134 (Has_Single_Return): Function returning unconstrained type cannot be
14135 inlined if expression in unique return statement is not an identifier.
14136 (Build_Body_To_Inline): It is possible to inline a function call that
14137 returns an unconstrained type if all return statements in the function
14138 return the same local variable. Subsidiary procedure Has_Single_Return
14139 verifies that the body conforms to this restriction.
14141 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
14142 same type, and one of them is of an anonymous access type, convert
14143 the other operand to it, so that this is a valid binary operation for
14145 (Resolve_Type_Conversion): Handle subtypes of protected types and
14146 task types when accessing to the corresponding record type.
14147 (Resolve_Allocator): Add '\' in 2-line warning message.
14148 Remove '!' in warning message.
14149 (Resolve_Call): Add '\' in 2-line warning message.
14150 (Valid_Conversion): Likewise.
14151 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
14152 resulting type may be an access type with an implicit dereference.
14153 Obtain the proper component from the designated type.
14154 (Make_Call_Into_Operator): Handle properly a call to predefined equality
14155 given by an expanded name with prefix Standard, when the operands are
14156 of an anonymous access type.
14157 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
14158 Explicit_Dereference and Resolve_Selected_Component, to verify that the
14159 prefix of the expression is not of an incomplete type. Allows full
14160 diagnoses of all semantic errors.
14161 (Resolve_Actuals): If the actual is an allocator whose directly
14162 designated type is a class-wide interface we build an anonymous
14163 access type to use it as the type of the allocator. Later, when
14164 the subprogram call is expanded, if the interface has a secondary
14165 dispatch table the expander will add a type conversion to force
14166 the displacement of the pointer.
14167 (Resolve_Call): If a function that returns an unconstrained type is
14168 marked Inlined_Always and inlined, the call will be inlined and does
14169 not require the creation of a transient scope.
14170 (Check_Direct_Boolean_Op): Removed
14171 (Resolve_Comparison_Op): Remove call to above
14172 (Resolve_Equality_Op): Remove call to above
14173 (Resolve_Logical_Op): Inline above, since this is only call.
14174 (Valid_Conversion): Handle properly conversions between arrays of
14175 convertible anonymous access types.
14178 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
14179 the literal in an unchecked conversion, because GCC 4.x needs a static
14180 value for a string bound.
14182 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14183 Hristian Kirtchev <kirtchev@adacore.com>
14185 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
14186 components of the corresponding record, take into account component
14187 definitions that are access definitions.
14188 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
14189 procedure is not considered a dispatching call and will be expanded
14192 2006-02-13 Javier Miranda <miranda@adacore.com>
14194 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
14195 controlling argument of the dispatching call is an abstract interface
14196 class-wide type then we use it directly.
14197 Check No_Dispatching_Calls restriction.
14198 (Default_Prim_Op_Position): Remove the code that looks for the last
14199 entity in the list of aliased subprograms. This code was wrong in
14201 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
14202 when the source is compiled with the No_Dispatching_Calls restriction.
14203 (Init_Predefined_Interface_Primitives): No need to inherit primitives
14204 if we are compiling with restriction No_Dispatching_Calls.
14205 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
14206 subprograms if we are compiling under No_Dispatching_Calls restriction.
14207 (Make_DT): Generate a dispatch table with a single dummy entry if
14208 we are compiling with the No_Dispatching_Calls restriction. In
14209 addition, in this case we don't generate code that calls to the
14210 following run-time subprograms: Set_Type_Kind, Inherit_DT.
14211 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
14212 of this subprogram if compiling with the No_Dispatching_Calls
14214 (Expand_Type_Conversion): Instead of using the actual parameter,
14215 the argument passed as parameter to the conversion function was
14216 erroneously referenced by the expander.
14217 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
14218 Set_Predefined_Primitive_Op_Address and Set_Signature.
14219 (Expand_Dispatching_Call): Generate call to
14220 Get_Predefined_Prim_Op_Address for predefined primitives.
14221 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
14222 predefined primitives.
14223 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
14224 primitives we reserve one dummy entry to ensure that the tag does not
14225 point to some memory that is associated with some other object. In
14226 addition, remove all the old code that generated the assignments
14227 associated with the signature of the dispatch table and replace them
14228 by a call to the new subprogram Set_Signature.
14229 (Set_All_DT_Position): Change the algorithm because now we have a
14230 separate dispatch table associated with predefined primitive operations.
14231 (Expand_Interface_Conversion): In case of non-static offset_to_top
14232 add explicit dereference to get access to the object after the call
14233 to displace the pointer to the object.
14234 (Expand_Interface_Thunk): Modify the generation of the actual used
14235 in the calls to the run-time function Offset_To_Top to fulfil its
14237 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
14239 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14241 * exp_dist.adb (Copy_Specification): For access parameters, copy
14242 Null_Exclusion flag, which will have been set for stream subprograms
14245 2006-02-13 Pascal Obry <obry@adacore.com>
14247 * expect.c (__gnat_expect_portable_execvp): New implementation. The
14248 previous implementation was using the C runtime spawnve routine but
14249 the corresponding wait was using directly the Win32 API. This was
14250 causing some times a lock when waiting for an event using
14251 WaitForSingleObject in __gnat_waitpid. This new implementation uses
14252 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
14253 API fixes this problem.
14255 2006-02-13 Robert Dewar <dewar@adacore.com>
14257 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

14265 array reference that is an explicit dereference, mark the converted
14266 (packed) array reference as analyzed to prevent a forthcoming
14267 reanalysis from resetting its type to the original (non-packed) array

14271 Javier Miranda <miranda@adacore.com>
14272 Eric Botcazou <ebotcazou@adacore.com>
14274 * exp_util.ads, exp_util.adb (Find_Prim_Op,
14275 Is_Predefined_Primitive_Operation): When
14276 searching for the predefined equality operator, verify that operands
14277 have the same type.
14278 (Is_Predefined_Dispatching_Operation): Remove the code that looks
14279 for the last entity in the list of aliased subprograms. This code
14280 was wrong in case of renamings.
14281 (Set_Renamed_Subprogram): New procedure
14282 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
14283 Exp_Type constant computed when entering this subprogram.
14284 (Known_Null): New function
14285 (OK_To_Do_Constant_Replacement): New function
14286 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
14287 (Side_Effect_Free): An attribute reference 'Input is not free of
14288 side effect, unlike other attributes that are functions. (from code
14290 (Remove_Side_Effects): Expressions that involve packed arrays or records
14291 are copied at the point of reference, and therefore must be marked as
14292 renamings of objects.
14293 (Is_Predefined_Dispatching_Operation): Return false if the operation is
14294 not a dispatching operation.
14297 (Remove_Side_Effects): Lift enclosing type conversion nodes for
14298 elementary types in all cases.
14300 2006-02-13 Javier Miranda <miranda@adacore.com>
14302 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
14303 task types when accessing to the corresponding record type.
14304 Remove '!' in warning message.
14306 2006-02-13 Olivier Hainque <hainque@adacore.com>
14308 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
14309 to avoid useless and space inefficient overalignments on targets where
14310 Max_Alignment is larger than 16.
14312 2006-02-13 Pascal Obry <obry@adacore.com>
14314 * g-catiio.adb (Sec_Number): New type used to compute the number of
14315 seconds since 1-1-1970.
14316 (Image) [Natural]: The parameter was an Integer, as we can't deal with
14317 negative numbers (years, months...) it is better to have a Natural here.
14319 (Image) [Number]: Change parameter from Long_Integer to Number.
14320 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
14321 overflow for dates past year 2038.
14323 2006-02-13 Matthew Heaney <heaney@adacore.com>
14325 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
14328 2006-02-13 Arnaud Charlet <charlet@adacore.com>
14330 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
14332 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
14333 finalization can occur normally.
14335 2006-02-13 Vincent Celier <celier@adacore.com>
14337 * gnatcmd.adb (Rules_Switches): New table
14338 (Add_To_Rules_Switches): New procedure
14339 (GNATCmd): For command CHECK, put all options following "-rules" in the
14340 Rules_Switches table. Append these -rules switches after the -cargs
14343 2006-02-13 Robert Dewar <dewar@adacore.com>
14345 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
14346 These two cases were generating incorrect output, and if this unit
14347 was built with checks on, generated a discriminant mismatch constraint
14350 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14351 Robert Dewar <dewar@adacore.com>
14353 * lib-xref.adb (Get_Type_Reference): For a private type whose full
14354 view is an array type, indicate the component type as well, for
14355 navigation purposes.
14356 (Generate_Reference): Don't consider array ref on LHS to be a case
14357 of violating pragma Unreferenced.
14358 Do not give Ada 2005 warning except on real reference.
14360 2006-02-13 Vincent Celier <celier@adacore.com>
14362 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
14363 main source, add switch -mdebug-main=_ada_ so that the executable can
14364 be debugged by the standard VMS debugger.
14365 (Gnatmake): Set No_Main_Subprogram to True when there is no main
14366 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
14367 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
14368 of the last source, as the binding and linking phases are never
14370 Set all executable obsolete when rebuilding a library.
14372 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
14375 2006-02-13 Javier Miranda <miranda@adacore.com>
14378 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
14379 code to improve the error message reported when the program has
14380 declarations of abstract interface types and it is not compiled with
14381 the -gnat05 switch.
14382 (P_Access_Definition): Reorganize the code to improve the error
14383 message reported when the new Ada 2005 syntax for anonymous
14384 access types is used and the program is not compiled with the

14389 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,
14390 stylesw.ads, usage.adb, vms_data.ads: Implement -gnatyI switch
14393 2006-02-13 Javier Miranda <miranda@adacore.com>
14395 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser

14400 * prj.adb (Reset): Initialize the first element of table Namings with
14401 the standard naming data.
14403 2006-02-13 Vincent Celier <celier@adacore.com>
14405 * prj.ads (Error_Warning): New enumeration type
14407 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
14408 unknown, use the location of the project to report the error.
14409 (When_No_Sources): New global variable
14410 (Report_No_Ada_Sources): New procedure
14411 (Check): New parameter When_No_Sources. Set value of global variable

14422 Call Recursive_Check with parameter When_No_Sources.
14423 (Recursive_Check): New parameter When_No_Sources. Call itself and
14424 Prj.Nmsc.Check with parameter When_No_Sources.
14425 (Process): New parameter When_No_Sources. Call Check with parameter
14427 (Copy_Package_Declarations): New procedure to copy renamed parameters
14428 and setting the location of the declared attributes to the location
14429 of the renamed package.
14430 (Process_Declarative_Items): Call Copy_Package_Declarations for renamed
14433 2006-02-13 Vincent Celier <celier@adacore.com>
14435 * prj-makr.adb (Make): Preserve the comments from the original project
14437 When removing nodes (attributes Source_Dirs, Source_Files,
14438 Source_List_File and package Naming), save the comments and attach the
14439 saved comments to the newly created nodes.
14440 Do not add a with clause for the naming package if one already exists.

14449 aliased entities to look for the overriden abstract interface
14451 (Is_Interface_Subprogram): Complete documentation.
14452 (Check_Dispatching_Operation): Do not generate code to register the
14453 operation in the dispatch table if the source is compiled with
14454 restriction No_Dispatching_Calls.
14455 (Override_Dispatching_Operation): Check for illegal attempt to override
14456 No_Return procedure with procedure that is not No_Return
14457 (Check_Dispatching_Call): Suppress the check for an abstract operation
14458 when the original node of an actual is a tag-indeterminate attribute
14459 call, since the attribute, which must be 'Input, can never be abstract.
14460 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
14461 call to the Input attribute (even when rewritten).
14462 (Propagate_Tag): Augment comment to indicate the possibility of a call
14463 to an Input attribute.
14465 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
14466 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
14468 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
14469 No_Wide_Characters is no longer partition-wide
14470 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
14473 2006-02-13 Douglas Rupp <rupp@adacore.com>
14475 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
14477 2006-02-13 Javier Miranda <miranda@adacore.com>
14479 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
14480 handles default-initialized components to keep separate the management
14481 of this feature but also avoid the unrequired resolution and
14482 expansion of components that do not have partially initialized
14484 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
14485 (Check_Bounds): Likewise.
14486 (Check_Length): Likewise.
14488 2006-02-13 Javier Miranda <miranda@adacore.com>
14489 Ed Schonberg <schonberg@adacore.com>
14491 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
14492 abstract interface type call analyze_and_resolve to expand the type
14493 conversion into the corresponding displacement of the
14494 reference to the base of the object.
14495 (Eval_Attribute, case Width): For systems where IEEE extended precision
14496 is supported, the maximum exponent occupies 4 decimal digits.
14497 (Accessibility_Message): Add '\' in 2-line warning message.
14498 (Resolve_Attribute): Likewise.
14499 (case Attribute_Access): Significantly revise checks
14500 for illegal access-to-subprogram Access attributes to properly enforce
14501 the rules of 3.10.2(32/2).
14502 Diagnose use of current instance with an illegal attribute.
14504 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
14506 (Enclosing_Generic_Unit): New function to return a node's innermost
14507 enclosing generic declaration node.
14508 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
14509 (Type_Access_Level): The accessibility level of anonymous acccess types
14510 associated with discriminants is that of the current instance of the
14511 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
14512 (Compile_Time_Constraint_Error): Handle case of conditional expression.
14513 (Kill_Current_Values_For_Entity): New function
14514 (Enter_Name): Change formal type to Entity_Id
14516 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
14517 Ed Schonberg <schonberg@adacore.com>
14518 Gary Dismukes <dismukes@adacore.com>
14520 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
14521 Analyze_Compilation_Unit.
14522 Detect and warn on redundant with clauses detected in a package spec
14523 and/or body when -gnatwr is used.
14524 (Analyze_Context): Analyze config pragmas before other items
14525 (Install_Context_Items): Don't analyze config pragmas here
14526 (Install_Limited_Withed_Unit): Set limited entity of package in
14527 with_clause so that cross-reference information or warning messages on
14528 unused packages can be properly generated
14529 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
14530 has Error_Posted set. Prevent infinite loops in illegal programs.
14531 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
14532 to the point of the error test requiring the current unit to be private.
14533 This ensures that private with clauses are not exempted from the basic
14534 checking for being a descendant of the same library unit parent as a
14535 withed private descendant unit.
14536 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
14537 handle private with clauses properly, as well as to account for cases
14538 where the withed unit is a public descendant of a private ancestor
14539 (in which case the current unit must be a descendant of the private
14540 ancestor's parent). The spec comments were updated accordingly. Also,
14541 the old error message in this subprogram was replaced with error
14542 messages that mirror the errors tested and reported by
14543 Check_Private_Child_Unit.
14544 Parameter and variable names improved for readability.
14545 (Install_Limited_Context_Clauses): Remove test for a withed unit being
14546 private as the precondition for calling
14547 Check_Private_Limited_Withed_Unit since that subprogram has been
14548 revised to test public units as well as private units.

14555 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
14556 that Scope_Stack.First = 1.
14557 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
14558 were not always properly handled previously.
14559 (Formal_Entity): Complete rewrite, to handle properly some complex case
14560 with multiple levels of parametrization by formal packages.
14561 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
14562 to the corresponding derived type declaration for proper semantics.
14564 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
14565 (Check_Component): Enforce restriction on components of
14566 unchecked_unions: a component in a variant cannot contain tasks or
14568 (Unchecked_Union): Allow nested variants and multiple discriminants, to
14570 Add pragma Ada_2005 (synonym for Ada_05)
14571 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
14572 were not always properly handled previously.
14573 Document that pragma Propagate_Exceptions has no effect
14574 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
14575 (Set_Convention_From_Pragma): Check that if a convention is
14576 specified for a dispatching operation, then it must be
14577 consistent with the existing convention for the operation.
14578 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
14579 longer required to specify an vtable-ptr component in the record. For
14580 compatibility reasons we leave the support for the previous definition.
14581 (Analyze_Pragma, case No_Return): Allow multiple arguments
14583 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
14584 non-overrideen inherited operation with a controlling result as
14585 illegal only its implicit declaration comes from the derived type
14586 declaration of its result's type.
14587 (Check_Possible_Deferred_Completion): Relocate the object definition
14588 node of the subtype indication of a deferred constant completion rather
14589 than directly analyzing it. The analysis of the generated subtype will
14590 correctly decorate the GNAT tree.
14591 (Record_Type_Declaration): Check whether this is a declaration for a
14592 limited derived record before analyzing components.
14593 (Analyze_Component_Declaration): Diagnose record types not explicitly
14594 declared limited when a component has a limited type.
14595 (Build_Derived_Record_Type): Code reorganization to check if some of
14596 the inherited subprograms of a tagged type cover interface primitives.
14597 This check was missing in case of a full-type associated with a private
14599 (Constant_Redeclaration): Check that the subtypes of the partial and the
14600 full view of a constrained deferred constant statically match.
14601 (Mentions_T): A reference to the current type in an anonymous access
14602 component declaration must be an entity name.
14603 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
14604 class_wide type to refer to full type, not to the incomplete one.
14605 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
14606 available. Required to give support to the certified run-time.
14607 (Analyze_Component_Declaration): In case of anonymous access components
14608 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
14609 (Process_Discriminants): For an access discriminant, use the
14610 discriminant specification as the associated_node_for_itype, to
14611 simplify accessibility checks.

14614 Javier Miranda <miranda@adacore.com>
14616 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
14617 abstract interpretations on an operator, remove interpretations that
14618 yield Address or a type derived from it, if one of the operands is an
14620 (Try_Object_Operation.Try_Primitive_Operation,
14621 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
14622 location when creating the new reference to a primitive or class-wide
14623 operation as a part of rewriting a subprogram call.
14624 (Try_Primitive_Operations): If context requires a function, collect all
14625 interpretations after the first match, because there may be primitive
14626 operations of the same type with the same profile and different return
14627 types. From code reading.
14628 (Try_Primitive_Operation): Use the node kind to choose the proper
14629 operation when a function and a procedure have the same parameter
14631 (Complete_Object_Operation): If formal is an access parameter and prefix
14632 is an object, rewrite as an Access reference, to match signature of
14633 primitive operation.
14634 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
14635 by an expanded name with prefix Standard, when the operands are of an
14636 anonymous access type.
14637 (Remove_Abstract_Operations): If the operation is abstract because it is
14638 inherited by a user-defined type derived from Address, remove it as
14639 well from the set of candidate interpretations of an overloaded node.
14640 (Analyze_Membership_Op): Membership test not applicable to cpp-class
14643 2006-02-13 Bob Duff <duff@adacore.com>
14645 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
14646 redundant use clauses.
14647 In particular, if the scope of two use clauses overlaps, but one is not
14648 entirely included in the other, we should not warn. This can happen
14649 with nested packages.
14650 (Analyze_Subprogram_Renaming): Protect the compiler against previously
14651 reported errors. The bug was reported when the compiler was built
14652 with assertions enabled.
14653 (Find_Type): If the node is a 'Class reference and the prefix is a
14654 synchronized type without a corresponding record, return the type
14657 2006-02-13 Javier Miranda <miranda@adacore.com>
14659 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
14660 if this is the full-declaration associated with a private declaration
14661 that implement interfaces, then the private type declaration must be
14663 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
14664 as aliased. The use of the 'access attribute is not available for such
14665 object (for this purpose the object should be explicitly marked as
14666 aliased, but being an anonymous type this is not possible).
14668 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14669 Robert Dewar <dewar@adacore.com>
14671 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
14672 compilation unit is an elaboration scope.
14673 (Add_Task_Proc): Add '\' in 2-line warning message.
14674 (Activate_All_Desirable): Deal with case of unit with'ed by parent
14676 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14677 Javier Miranda <miranda@adacore.com>
14679 * sem_type.adb (Write_Overloads): Improve display of candidate
14681 (Add_One_Interp): Do not add to the list of interpretations aliased
14682 entities corresponding with an abstract interface type that is an
14683 immediate ancestor of a tagged type; otherwise we have a dummy
14684 conflict between this entity and the aliased entity.
14685 (Disambiguate): The predefined equality on universal_access is not
14686 usable if there is a user-defined equality with the proper signature,
14687 declared in the same declarative part as the designated type.
14688 (Find_Unique_Type): The universal_access equality operator defined under
14689 AI-230 does not cover pool specific access types.
14690 (Covers): If one of the types is a generic actual subtype, check whether
14691 it matches the partial view of the other type.
14693 2006-02-13 Thomas Quinot <quinot@adacore.com>
14695 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
14696 line. This is necessary to allow In_Extended_Main_Unit to provide
14697 correct results for itypes while writing out expanded source.
14698 (Close_File): No need to update the source_index_table here since it's
14699 now done for each line.
14701 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14702 Robert Dewar <dewar@adacore.com>
14704 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
14705 preserve the source unit where the itype is declared, and prevent a
14707 (Note_Implicit_Run_Time_Call): New procedure
14708 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
14711 * sprint.ads: Document use of $ for implicit run time routine call
14713 2006-02-13 Quentin Ochem <ochem@adacore.com>
14715 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
14718 2006-02-13 Bob Duff <duff@adacore.com>
14720 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
14721 Scan_Unsigned, so we do not scan leading blanks and sign twice.
14722 Integer'Value("- 5") and Integer'Value("-+5") now correctly
14723 raise Constraint_Error.
14725 * s-vallli.adb (Scan_Long_Long_Integer): Call
14726 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
14727 do not scan leading blanks and sign twice.
14728 Integer'Value("- 5") and Integer'Value("-+5") now correctly
14729 raise Constraint_Error.
14731 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
14732 Scan_Long_Long_Unsigned): Split out most of the processing from
14733 Scan_Long_Long_Unsigned out into
14734 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
14735 This prevents scanning leading blanks and sign twice.
14736 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
14739 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
14740 out most of the processing from Scan_Unsigned out into
14741 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
14742 This prevents scanning leading blanks and sign twice.
14744 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
14745 use with Modular'Value attribute.
14746 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
14749 2006-02-13 Robert Dewar <dewar@adacore.com>
14751 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
14753 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

14944 * a-taster.ads, a-taster.adb: New files.
14946 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
14947 link to the version that does nothing. This way the task termination
14948 routine is not executed twice for the environment task when finishing
14949 because of an unhandled exception.
14951 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
14952 handler because of an unhandled exception.
14954 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
14955 System.Tasking.Utilities instead of that in System.Tasking.Stages.
14957 * s-finimp.adb (initialization code): Modify the soft link for the
14958 finalization of the global list instead of Adafinal.
14960 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
14961 non-tasking version of the soft link for task termination. We do
14962 nothing since if we are using the non-tasking version it
14963 means that the task termination functionality is not used.
14964 (Null_Finalize_Global_List): Add this null version for the procedure
14965 in charge of finalizing the global list for controlled objects.
14966 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
14967 instead for handling run-time termination in a more flexible way.
14968 (Adafinal_NT): This new procedure will take care of finalizing the
14969 global list for controlled objects if needed, but no tasking
14972 * s-tarest.adb (Task_Lock): Do not try to lock again the
14973 Global_Task_Lock if we already own it. Otherwise, we get blocked in
14974 some run-time operations.
14975 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
14976 until all nested locks have been released.
14977 (Task_Wrapper): Call the fall-back task termination handler. It
14978 applies to all tasks but the environment task.
14979 (Finalize_Global_Tasks): Add the call for the task termination
14980 procedure for the environment task.
14981 (Task_Wrapper): suppress warnings around declaration of
14982 Secondary_Stack_Address.
14984 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
14985 moved to the Common_ATCB record.
14986 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
14987 Common_ATCB record.
14988 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
14989 Common_ATCB record.
14991 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
14992 Fall_Back_Handler, and Specific_Handler.
14994 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
14995 defined in Ada.Task_Termination, to avoid circular dependencies.
14996 (Termination_Handler): Redefine this type here, alredy defined in
14997 Ada.Task_Termination, for avoiding circular dependencies.
14998 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
14999 for storing task termination handlers. In addition,
15000 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
15001 Common_ATCB because it is used by both the regular and the restricted
15003 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
15004 Common_ATCB because it is used by both the regular and the restricted
15006 (Common_ATCB): Added a dynamic task analyzer field.
15008 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
15009 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
15010 (Task_Wrapper): Call the task termination handler. It applies to all
15011 tasks but the environment task.
15012 (Finalize_Global_Tasks): Call the task termination procedure for the
15013 environment task. The call to Finalize_Global_List is now performed
15014 using the soft links mechanism.
15015 (Task_Wrapper): added dynamic stack analysis.
15017 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
15018 potentially blocking operations has been moved from
15019 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
15020 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
15021 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
15022 this run-time check.
15024 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
15025 of task termination procedure.
15026 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
15027 link for the task termination procedure.
15029 * bindusg.adb: (Bindusg): Added documentation for -u option.

15043 (Standart_Output): new subprogram
15044 (Set_Output): new subprogram
15045 (Put): now uses the value of Current_Out to know if the output has to be
15046 send to stderr or stdout.
15048 * s-stausa.ads: Complete implementation.
15050 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
15052 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
15053 list of Ada 05 files.
15054 (GNAT Library Units): Add AltiVec files.

15057 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
15058 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
15060 2005-12-09 Nicolas Setton <setton@adacore.com>

15063 file_name is empty.
15065 2005-12-09 Javier Miranda <miranda@adacore.com>
15066 Hristian Kirtchev <kirtchev@adacore.com>
15068 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
15069 to the specification because the frontend generates code that uses this
15071 (Set_Interface_Table): Add missing assertion.
15072 Update documentation describing the run-time structure.
15073 (Displace): New subprogram that displaces the pointer to the object
15074 to reference one of its secondary dispatch tables.
15075 (IW_Membership): Modified to use the new table of interfaces.
15076 (Inherit_TSD): Modified to use the new table of interfaces.

15078 contents of the new table of interfaces.
15079 (Set_Interface_Table): New subprogram that stores in the TSD the
15080 pointer to the table of interfaces.

15094 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
15095 in all the calls to Expand_Interface_Thunk. Instead of referencing the
15096 record component containing the tag of the secondary dispatch table we
15097 have to use the Offset_To_Top run-time function to get this information;
15098 otherwise if the pointer to the base of the object has been displace
15099 we get a wrong value if we use the 'position attribute.
15101 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
15102 all the calls to Expand_Interface_Thunk.
15103 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

15107 at the header of the generated list.
15108 (Expand_Interface_Conversion): Handle the case in which the displacement
15109 associated with the interface conversion is not statically known. In

15137 RE_TK_Tagged, RE_TK_Task.
15139 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
15140 Init_Secondary_Tags_Internal to allow its use with interface types and
15141 also to generate the code for the new additional actual required
15142 by Set_Offset_To_Top.
15143 (Build_Init_Statements): In case of components associated with abstract
15144 interface types there is no need to generate a call to its IP.

15156 properly protected objects and attach handler in the case of the
15157 restricted profile.

15170 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
15171 pointer initialization values. Make a SAVE_EXPR instead. Add comments
15172 about the use and expansion of SAVE_EXPRs in the various possible
15173 renaming handling cases.
15174 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
15175 abusing DECL_FCONTEXT.

15275 covered by the tag of the source.
15277 2005-12-09 Robert Dewar <dewar@adacore.com>
15279 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

15294 component associated with the secondary table of an abstract interface
15295 type, return the entity associated with such abstract interface type.
15296 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
15297 base type to create anonymous subtype, because entity may be a locally
15298 declared subtype or generic actual.
15299 (Find_Interface): New subprogram that given a tagged type and one of its
15300 component associated with the secondary table of an abstract interface
15301 type, return the entity associated with such abstract interface type.

15343 legal within a protected type that implements an interface.
15344 (Collect_Interfaces): Do not add to the list the interfaces that
15345 are implemented by the ancestors.
15346 (Derived_Type_Declaration): If the parent of the full-view is an
15347 interface perform a transformation of the tree to ensure that it has
15348 the same parent than the partial-view. This simplifies the job of the
15349 expander in order to generate the correct object layout, and it is
15350 needed because the list of interfaces of the full-view can be given in
15352 (Process_Full_View): The parent of the full-view does not need to be
15353 a descendant of the parent of the partial view if both parents are
15355 (Analyze_Private_Extension_Declaration): If declaration has an explicit
15356 "limited" the parent must be a limited type.

15370 (Process_Full_View): Improve the check for the "no hidden interface"
15371 rule as defined by AI-396.
15373 2005-12-09 Robert Dewar <dewar@adacore.com>

15430 available user-specified stream attributes on limited parameters to
15431 also test the type directly rather than only its underlying type (for
15432 Ada 95) and, in the case of Ada 2005, to check that the user-specified
15433 attributes are visible at the point of the subprogram declaration.
15434 For Ada 2005, the error message is modified to indicate that the
15435 type's stream attributes must be visible (again, only for -gnat05).

15602 Roger Sayle <roger@eyesopen.com>
15605 * misc.c (internal_error_function): Don't use vsprintf to format

15617 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
15618 a temporary if taking the address of something that is neither
15619 reference, declaration, or constant, since the gimplifier
15620 can't handle that case.
15622 2005-11-17 Laurent Guerby <laurent@guerby.net>

15692 * gen-soccon.c: Complete value expansion should not be performed on
15693 TARGET, as it has the form of a math expression, and some components
15694 may be platform-defined macros.
15695 For VxWorks, generate the OK and ERROR values.
15696 New constants giving the sizes of the components of C struct timeval.

15708 deal with different cases of static and dynamic elaboration checks (all
15709 checks does not count in the first case, but does in the second).

15715 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
15716 elementary types using the operator in standard. It is cleaner not to
15717 modify the programmers intent, especially in the case of floating-point.
15718 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
15719 it did not matter because we always rewrote a/=b to not(a=b).
15720 (Expand_Allocator_Expression): For an allocator expression whose nominal
15721 subtype is an unconstrained packed type, convert the expression to its
15722 actual constrained subtype.
15723 Implement warning for <= or >= where < or > not possible
15724 Fix to Vax_Float tests (too early in many routines, causing premature
15725 Vax_Float expansions.
15727 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
15728 to be used with packages and generic packages as well as with

15731 of pragma Suppress (All_Checks)
15732 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
15733 a string literal for precise control over warnings.

15743 Allow optional = after -gnatm
15744 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
15745 longer sets Elaboration_Checks.
15746 Code to set warning mode moved to Sem_Warn
15747 so that it can be shared by pragma processing.
15749 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
15752 * s-taprop-solaris.adb:
15753 Change some <= to =, to avoid new warning

15759 2005-11-14 Robert Dewar <dewar@adacore.com>
15761 * exp_vfpt.adb: Handle /= case
15762 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
15763 so that we do not get duplicate scaling for fixed point conversions.
15765 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
15767 2005-11-14 Matthew Gingell <gingell@adacore.com>
15769 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
15770 Increase default priority on Lynx from 15 to 17, and meet the Ada
15771 requirement that Default_Priority be ((Priority'First +
15772 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

15874 we are not defining the type.
15875 <E_Record_Type>: Likewise.
15876 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
15877 to get advantage of the new maybe_stabilize_reference interface, to
15878 ensure that what we reference is indeed stabilized instead of relying
15879 on assumptions on what the stabilizer does.
15880 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
15881 type imported through a limited_with clause, use its non-limited view.
15882 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
15884 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
15885 of #if sections + explicit comparisons of convention identifiers.

15887 before early-returning for certain types when code generation is
15889 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

15891 that we are not defining.
15892 (elaborate_expression_1): Do not create constants when creating
15893 variables needed by the debug info: the dwarf2 writer considers that
15894 CONST_DECLs is used only to represent enumeration constants, and emits
15896 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
15897 object with an address clause into an indirect reference, drop the
15898 initializing expression.

15909 if there is an actual subtype provided by the front-end, use that
15910 subtype to build an actual type with bounds template.
15911 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
15912 is provided by the front-end, use that subtype to compute the size of
15913 the deallocated object.
15914 (gnat_to_gnu): When adding a statement into an elaboration procedure,
15915 check for a potential violation of a No_Elaboration_Code restriction.
15916 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
15917 with extra arguments to control whether to recurse through non-values
15918 and to let the caller know if the stabilization has succeeded.

15920 maybe_stabilize, for common uses without restriction on lvalues and
15921 without need to check for the success indication.
15922 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
15923 pass false instead of 0 as the FORCE argument which is a bool.
15924 (Identifier_to_gnu): Remove checks ensuring that an renamed object
15925 attached to a renaming pointer has been properly stabilized, as no such
15926 object is attached otherwise.
15927 (call_to_gnu): Invoke create_var_decl to create the temporary when the
15928 function uses the "target pointer" return mechanism.
15929 Reinstate conversion of the actual to the type of the formal
15930 parameter before any other specific treatment based on the passing
15931 mechanism. This turns out to be necessary in order for PLACEHOLDER
15932 substitution to work properly when the latter type is unconstrained.

15936 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

15938 and to let the caller know if the stabilization has succeeded.
15940 * utils2.c (gnat_build_constructor): Only sort the fields for possible
15941 static output of record constructor if all the components are constant.
15942 (gnat_build_constructor): For a record type, sort the list of field
15943 initializers in increasing bit position order.
15944 Factor common code to build a storage type for an unconstrained object
15945 from a fat or thin pointer type and a constrained object type.
15946 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
15947 types variants, and process special cases of VIEW_CONVERT expressions
15948 as their NOP_EXPR counterpart to ensure we get to the
15949 CORRESPONDING_VARs associated with CONST_DECls.
15950 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
15951 on the right-hand side.

15958 extracting the object if converting to a type variant.
15959 (create_var_decl): When a variable has an initializer requiring code
15960 generation and we are at the top level, check for a potential violation
15961 of a No_Elaboration_Code restriction.
15962 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
15963 SIZE and SIZE_UNIT which we need for later back-annotations.

15965 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
15966 is an unchecked union.
15967 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
15968 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
15969 main variant, just replace the VIEW_CONVERT_EXPR.

16105 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
16106 for task component, in the case of a limited aggregate. The enclosed

16148 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
16149 'Unrestricted_Access, if the designated type is an interface we
16150 add a type conversion to force the displacement of the pointer

16154 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
16155 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
16156 'Terminated for task interface class-wide objects. Generate a call to
16157 the predefined dispatching routine used to retrieve the _task_id from

16187 the return value into its actual subtype in order to help the backend
16188 to return the actual size instead of the maximum. This is another

16238 attribute of the N_Free_Statement.
16239 Generate itype for classwide designated object in both cases of
16240 user-specified storage pool: specific and class-wide, not only in the
16242 Raise CE when trying to set a not null access type object to null.

16514 view is a transitive derivation of the ancestor of the partial view.
16515 (Process_Full_View): Rename local subprogram Find_Interface_In_
16516 Descendant to Find_Ancestor_Interface to leave the code more clear.
16517 Remove wrong code that avoids the generation of an error message
16518 when the immediate ancestor of the partial view is an interface.
16519 In addition some minor reorganization of the code has been done to
16520 leave it more clear.
16521 (Analyze_Type_Declaration): If type has previous incomplete tagged
16522 partial view, inherit properly its primitive operations.

16535 and derived protected types, the parent may be an interface that must
16536 be included in the interface list.
16537 (Access_Definition): If the designated type is an interface that may
16538 contain tasks, create Master_Id for it before analyzing the expression
16539 of the declaration, which may be an allocator.

16574 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
16575 not try to rewrite a renamed stream attribute, because the operations
16576 on the type may not have been generated.

16578 whose default is abstract because the object type itself is abstract.
16579 (Find_Type): If the type is incomplete and appears as the prefix of a
16580 'Class reference, it is tagged, and its list of primitive operations
16581 must be initialized properly.
16582 (Chain_Use_Clauses): When chaining the use clauses that appear in the
16583 private declaration of a parent unit, prior to compiling the private
16584 part of a child unit, find on the scope stack the proper parent entity
16585 on which to link the use clause.

16615 precision float type for the generated code (prevents gratuitous
16616 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
16617 (Resolve_Concatenation_Arg): Improve error message when argument is an
16618 ambiguous call to a function that returns an array.
16619 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
16620 there is an implicit operator in the given scope if we are within an
16621 instance: legality check has been performed on the generic.
16622 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
16623 after resolving operand, to avoid false warnings on overloaded calls.

17345 code generated by the expander.
17346 (Expand_Interface_Conversion): If the actual is an access type then
17347 build an internal function to handle the displacement. If the actual
17348 is null this function returns null because no displacement is
17349 required; otherwise performs a type conversion that will be
17350 expanded in the code that returns the value of the displaced actual.
17351 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
17352 conversions that have no effect in the generated code because no

17616 whether a potential circularity is harmless, because it includes units
17617 loaded through a limited_with clause. Extends previous treatment which
17618 did not handle properly arbitrary combinations of limited and
17619 non-limited clauses.
17621 2005-09-01 Nicolas Setton <setton@adacore.com>
17623 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
17624 to be encoded as typ___XBLU_lowerbound__upperbound instead of
17625 typ___XB_lowerbound__upperbound.
17627 2005-09-01 Thomas Quinot <quinot@adacore.com>
17629 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
17630 dummy access formal for RACW/RAS TypeCode TSS.
17631 (Build_TypeCode_Call): Do not generate dummy null access actual for
17632 calls to the TypeCode TSS.
17634 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17636 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
17637 fully qualified name, to distinguish instances with the same local name.
17639 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
17642 2005-09-01 Robert Dewar <dewar@adacore.com>

17649 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
17650 (Free): New deallocation procedure for filter elements
17651 (Close): Deallocate any existing filter for the concerned connection
17653 2005-09-01 Laurent Pautet <pautet@adacore.com>
17655 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
17656 position set is provided, we compute one in order to reduce the maximum
17657 length of the keys. This computation first selects a character
17658 position between 1 and the minimum length of the keys in order to
17659 avoid reducing one of the keys to an empty string.
17660 (Initialize, Compute): When the ratio V to K is too low, the algorithm
17661 does not converge. The initialization procedure now comes with a
17662 maximum number of iterations such that when exceeded, an exception is
17663 raised in Compute. The user can initialize this ratio to another value
17665 Reformating and updated headers.
17667 2005-09-01 Javier Miranda <miranda@adacore.com>
17669 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
17670 that given an entity T creates and returns an Itype that duplicates the
17671 contents of T. The returned Itype has the null-exclusion
17672 attribute set to True, and its Etype attribute references T
17673 to keep the association between the two entities.
17674 Update copyright notice
17676 * sem_aggr.adb (Check_Can_Never_Be_Null,
17677 Aggregate_Constraint_Checks, Resolve_Aggregate,
17678 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
17680 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

17683 Robert Dewar <dewar@adacore.com>
17684 Hristian Kirtchev <kirtchev@adacore.com>
17686 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
17689 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
17691 Call Set_Result_Definition instead of Set_Subtype_Mark.
17692 (P_Subprogram_Specification): Add parsing of anonymous access result
17693 plus null exclusions. Call Set_Result_Definition instead of
17696 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
17697 (P_Access_Type_Definition): Add parsing for an anonymous access result
17698 subtype, plus parsing for null exclusions. Call Set_Result_Definition
17699 instead of Set_Subtype_Mark.
17701 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
17702 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
17703 (Result_Definition): New function for N_Function_Specifications.
17704 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
17705 N_Function_Specification.
17706 (Set_Null_Exclusion_Present): Allow this flag for
17707 N_Function_Specification.
17708 (Set_Result_Definition): New procedure for N_Function_Specifications.
17709 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
17710 and N_Function_Specification.
17712 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
17713 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
17714 Add support for LIMITED NEW for Ada 2005 AI-419
17715 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
17716 syntax for anonymous access results.
17717 Replace Subtype_Mark field by Result_Definition in
17718 N_Function_Specification and N_Access_Definition specs.
17719 Add Null_Exclusion_Present to spec of N_Function_Specification.
17720 (Result_Definition): New function for N_Function_Specification and
17721 N_Access_Function_Definition.
17722 (Set_Result_Definition): New procedure for N_Function_Specification and
17723 N_Access_Function_Definition.
17725 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
17726 Result_Definition for cases of N_Access_Function_Definition and
17727 N_Function_Specification.
17728 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
17730 2005-09-01 Vincent Celier <celier@adacore.com>
17732 * lib-writ.adb: Update Copyright notice
17733 (Write_With_Lines): On platforms where file names are case-insensitive,
17734 record the file names in lower case.
17735 (Write_ALI): For D lines, on platforms where file names are
17736 case-insensitive, record the file names in lower case.
17738 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17739 Emmanuel Briot <briot@adacore.com>
17741 * lib-xref.adb (Output_Overridden_Op): Display information on
17742 overridden operation.
17744 * lib-xref.ads: Add documentation on overridden operations.
17746 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
17749 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
17750 overriding entity information.
17752 2005-09-01 Vincent Celier <celier@adacore.com>
17754 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
17755 including those that are inherited.
17757 2005-09-01 Robert Dewar <dewar@adacore.com>
17759 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
17761 * par-prag.adb: Implement new pragma Debug_Policy
17763 * sem_prag.adb Implement new pragma Debug_Policy
17764 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
17765 Component_Size attribute specification. Give warning for ignored pragma
17768 * snames.h, snames.ads, snames.adb: Introduce entries in
17769 Preset_Names for Name_Disp_Asynchronous_Select,
17770 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
17771 Name_Disp_Timed_Select.
17772 New pragma Debug_Policy
17774 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
17776 Switch -gnata also sets Debug_Pragmas_Enabled
17778 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
17779 handle an explicit -gnata when compiling predefined files.
17781 2005-09-01 Vincent Celier <celier@adacore.com>
17783 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
17784 directories of projects that have no Ada sources.
17786 2005-09-01 Robert Dewar <dewar@adacore.com>
17788 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
17789 (makes a difference for wide characters)
17791 * widechar.adb, widechar.ads:
17792 Add Wide_Char_Byte_Count feature to count chars vs bytes
17794 2005-09-01 Thomas Quinot <quinot@adacore.com>
17795 Ed Schonberg <schonberg@adacore.com>
17796 Robert Dewar <dewar@adacore.com>
17798 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
17799 'Address attribute reference with an overloaded prefix, use the
17800 location of the prefix (not the location of the attribute reference) as
17801 the error location.
17802 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
17803 a function renaming thereof, is a valid prefix for 'Size (where it is
17804 intepreted as a function call).
17805 (Statically_Denotes_Entity): New predicate to determine whether the
17806 prefix of an array attribute can be considered static.
17809 (Eval_Attr): Fix failure to evaluate Component_Size for
17810 unconstrained arrays (resulted in wrong value in packed case, since
17811 back end cannot handle this case)
17813 2005-09-01 Robert Dewar <dewar@adacore.com>
17815 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
17816 error msgs for most common cases.
17817 Use new errout insertion char < (conditional warning)
17819 2005-09-01 Javier Miranda <miranda@adacore.com>
17820 Ed Schonberg <schonberg@adacore.com>
17822 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
17823 become local to the whole package.
17824 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
17825 the package was already analyzed the new algorithm "replaces" the
17826 real entities by the shadow ones. This is required to ensure that
17827 the order of these entities in the homonym chains does not change;
17828 otherwise we can have undefined references at linking time because
17829 in case of conflicts the external name of the entities will have
17830 a suffix that depends on the order of the entities in the chain.
17831 (Remove_Limited_With_Clause): Complementary code that completes the
17832 new algorithm and replaces the shadow entities by the real ones.
17833 (Install_Limited_Withed_Unit): When unchaining entities before the
17834 installation of the shadow entities, only regular entities of the
17835 public part must be taken into account. This is required to
17836 keep this routine in synch with the work done by Remove_Limited_
17838 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
17839 even if unit is analyzed, because the analysis of the unit is
17840 idempotent in any case, and the limited view of the unit may have to
17841 be installed for proper visibility.
17842 (Expand_Limited_With_Clause): Even if the unit in the implicit
17843 with_clause has been analyzed already, a limited view of the package
17844 must be built for the current context, if it does not exist yet.
17846 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17847 Javier Miranda <miranda@adacore.com>
17848 Gary Dismukes <dismukes@adacore.com>
17850 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
17851 defining entity for the instance body, make a new defining identifier
17852 rather than copying the entity of the spec, to prevent accidental
17853 sharing of the entity list.
17854 (Check_Private_View): When exchanging views of private types, build the
17855 list of exchanged views as a stack, to ensure that on exit the exchanges
17856 are undone in the proper order.
17857 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
17858 Restore the compilation environment in case of instantiation_error.
17859 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
17860 for an anonymous access result.
17861 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
17862 (Formal_Entity): Handle properly the case of a formal package that
17863 denotes a generic package renaming.
17865 2005-09-01 Thomas Quinot <quinot@adacore.com>
17867 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
17868 clause if the array aggregate is surrounded by parentheses.
17870 2005-09-01 Cyrille Comar <comar@adacore.com>
17871 Gary Dismukes <dismukes@adacore.com>
17872 Ed Schonberg <schonberg@adacore.com>
17873 Javier Miranda <miranda@adacore.com>
17875 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
17877 to check if a type is Constrained in cases related to code generation
17878 (rather than semantic checking) since otherwise we do not generate
17879 similar code for mutable private types depending if their
17880 discriminants are visible or not.
17881 (Check_Abstract_Overriding): Do not complain about failure to override
17882 the primitive operations used in dispatching selects since they will
17883 always be overriden at the freeze point of the type.
17884 (Access_Definition): Separate out handling for resetting the scope
17885 of an anonymous access function result type. Retrieve the scope
17886 of the associated function rather than using Current_Scope, which
17887 does not have a consistent value (depends on whether we're in the
17888 middle of analyzing formal parameters). Add ??? comment about
17889 finding a cleaner way to handle the special cases of scope setting.
17890 (Process_Incomplete_Dependents): A protected operation is never a
17891 dispatching operation (only its wrapper may be).
17892 (Build_Derived_Record_Type): In case of tagged private types that
17893 implement interfaces add derivation of predefined primitive
17895 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
17896 by two parameters that are used in case of derivation from abstract
17897 interface types: No_Predefined_Prims is used to avoid the derivation
17898 of predefined primitives from the interface, and Predefined
17899 Prims_Only is used to complete the derivation predefined primitives
17900 in case of private tagged types implementing interfaces.
17901 Fix typo in comments
17902 (Find_Interface_In_Descendant): Protect the frontend against
17903 wrong code with large circularity chains.
17904 (Is_Private_Overriding): Add support for entities overriding interface
17905 subprograms. The test failed because Entities associated with overriden
17906 interface subprograms are always marked as hidden (and used to build
17907 the secondary dispatch table); in this case the overriden entity is
17908 available through the field abstract_interface_alias (cf. override_
17909 dispatching_operation)
17910 (Access_Definition): Set the scope of the type to Current_Scope for the
17911 case of a function with an anonymous access result type.
17912 (Access_Subprogram_Declaration): Handle creation of the type entity for
17913 an access-to-function type with an anonymous access result.
17914 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
17915 in handling for N_Access_Function_Definition.
17916 (Analyze_Subtype_Declaration): Modify the text of error message.
17917 (Derived_Type_Declaration): Modify the text of error message.
17918 (Process_Subtype): Modify the text of error message plus cleanup
17919 of one redundant error message.
17920 (Analyze_Component_Declaration): Code cleanup.
17921 (Analyze_Object_Declaration): Code cleanup.
17922 (Analyze_Subtype_Declaration): Propagate the null-exclusion
17923 attribute in case of access types. Code cleanup.
17924 (Array_Type_Declaration): Code cleanup.
17925 (Process_Discriminants): Create the new null-excluding itype
17926 if required. Code cleanup.
17927 (Process_Subtype): Create the new null-excluding itype if
17928 required. Code cleanup.
17929 (Build_Derived_Record_Type): Code cleanup to avoid calling
17930 twice the subprogram derive_subprograms in case of private
17931 types that implement interfaces. In this particular case the
17932 subprogram Complete_Subprograms_Derivation already does the
17933 job associated with the second call.
17935 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
17936 conversion to the full view when generating an operation for a
17937 discriminant whose type may currently be private.
17939 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17940 Javier Miranda <miranda@adacore.com>
17942 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
17943 V (Obj.F), the rewriting does not involve the indexed component, but
17944 only the selected component itself.
17945 Do not apply the transformation if the analyzed node is an actual of a
17946 call to another subprogram.
17947 (Complete_Object_Operation): Retain the entity of the
17948 dispatching operation in the selector of the rewritten node. The
17949 entity will be used in the expansion of dispatching selects.
17950 (Analyze_One_Call): Improve location of the error message associated
17952 (Analyze_Selected_Component): No need to resolve prefix when it is a
17953 function call, resolution is done when parent node is resolved, as
17955 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
17956 when attempting to resolve a call transformed from its object notation.
17957 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
17958 of the argument list for each interpretation of the operation.
17959 (Try_Object_Operation): The designated type of an access parameter may
17960 be an incomplete type obtained through a limited_with clause, in which
17961 case the primitive operations of the type are retrieved from its full
17963 (Analyze_Call): If this is an indirect call, and the return type of the
17964 access_to_subprogram is incomplete, use its full view if available.
17966 2005-09-01 Javier Miranda <miranda@adacore.com>
17967 Gary Dismukes <dismukes@adacore.com>
17969 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
17970 access types the null-exclusion and access-to-constant attributes must
17972 (Analyze_Return_Statement): When the result type is an anonymous access
17973 type, apply a conversion of the return expression to the access type
17974 to ensure that appropriate accessibility checks are performed.
17975 (Analyze_Return_Type): For the case of an anonymous access result type,
17976 generate the Itype and set Is_Local_Anonymous_Access on the type.
17977 Add ??? placeholder for check to disallow returning a limited object
17978 in Ada 2005 unless it's an aggregate or a result of a function call.
17979 Change calls from Subtype_Mark to Result_Definition.
17980 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
17981 Result_Definition in call to Make_Function_Specification.
17982 (Build_Body_To_Inline): Change Set_Subtype_Mark to
17983 Set_Result_Definition.
17984 (Make_Inequality_Operator): Change formal Subtype_Mark to
17985 Result_Definition in call to Make_Function_Specification.
17986 (Process_Formals): Create the new null-excluding itype if required.
17987 (New_Overloaded_Entity): For an entity overriding an interface primitive
17988 check if the entity also covers other abstract subprograms in the same
17989 scope. This is required to handle the general case, that is, overriding
17990 other interface primitives and overriding abstract subprograms inherited
17991 from some abstract ancestor type.
17992 (New_Overloaded_Entity): For an overriding entity that comes from
17993 source, note the operation that it overrides.
17994 (Check_Conformance, Type_Conformant): Addition of one new formal
17995 to skip controlling formals in the analysis. This is used to
17996 handle overloading of abstract interfaces.
17997 (Base_Types_Match): Add missing case for types imported from
17998 limited-with clauses
17999 (New_Overloaded_Entity): Add barrier to protect the use of
18000 the "alias" attribute.
18002 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18004 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
18005 verify that the procedure and the entry are mode conformant.
18006 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
18007 as a different operator, which is often a cut-and-paste error.
18009 2005-09-01 Javier Miranda <miranda@adacore.com>
18010 Ed Schonberg <schonberg@adacore.com>
18012 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
18013 used in controlling parameters exclude null because it is necessary to
18014 read the tag to dispatch, and null has no tag.
18015 (Override_Dispatching_Operation): If the previous operation is inherited
18016 from an interface, it becomes hidden and does not participate in later
18019 2005-09-01 Javier Miranda <miranda@adacore.com>
18020 Ed Schonberg <schonberg@adacore.com>
18021 Gary Dismukes <dismukes@adacore.com>
18023 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
18024 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
18025 the expander will generate the corresponding run-time check to evaluate
18027 (Resolve_Call): Check for legal type of procedure name or prefix that
18028 appears as a trigger in a triggering alternative.
18029 (Valid_Conversion): If expression is ambiguous and the context involves
18030 an extension of System, remove System.Address interpretations.
18031 (Resolve_Qualified_Expression): Reject the case of a specific-type
18032 qualification applied to a class-wide argument. Enhance comment
18033 to explain checking of Original_Node.
18034 (Resolve_Type_Conversion): The location of the error message was not
18035 general enough to handle the general case and hence it has been removed.
18036 In addition, this patch improves the text of the message.
18037 (Resolve_Type_Conversion): Add missing support for access to interface
18039 (Resolve_Type_Conversion): If the target is a class-wide interface type,
18040 do not expand if the expression is the actual in a call, because proper
18041 expansion will take place when the call itself is expanded.
18042 (Resolve_Allocator): If the context is an unchecked conversion, the
18043 allocator inherits its storage pool, if any, from the target type of
18046 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18047 Javier Miranda <miranda@adacore.com>
18049 * sem_type.adb (Add_One_Interp): If a candidate operation is an
18050 inherited interface operation that has an implementation, use the
18051 implementation to avoid spurious ambiguities.
18052 (Interface_Present_In_Ancestor): In case of concurrent types we can't
18053 use the Corresponding_Record_Typ attribute to look for the interface
18054 because it is set by the expander (and hence it is not always
18055 available). For this reason we traverse the list of interfaces
18056 (available in the parent of the concurrent type).
18057 (Interface_Present_In_Ancestor): Handle entities from the limited view
18059 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18061 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
18062 from the list of required components.
18063 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
18064 primitive procedure of a limited interface with a controlling first
18066 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
18068 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
18069 capture if it is generated in the second operand of a short-circuit
18071 Do not capture values for variables with address clauses.
18072 (Is_Object_Reference): Treat a function call as an object reference only
18073 if its type is not Standard_Void_Type.
18075 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18077 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
18078 to a variable that is statically known to be constant.
18080 2005-09-01 Geert Bosch <bosch@adacore.com>
18081 Robert Dewar <dewar@adacore.com>
18083 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.
18084 (VAXGF_Safe_First): Idem.

19301 If the program has a null default, generate an empty body for it.
19303 * sem_ch6.adb, sem_ch9.adb (Analyze_Subprograms_Declaration): Update
19304 error message condition, null procedures are correctly detected now.
19305 (New_Overloaded_Entity): Bypass trivial overriding indicator check
19306 for subprograms in the context of protected types. Instead, the
19307 indicator is examined in Sem_Ch9 while analysing the subprogram
19309 (Check_Overriding_Indicator): Check consistency of overriding indicator
19310 on subprogram stubs as well.
19311 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
19313 (Analize_Subprogram_Specification): When analyzing a subprogram in which

19315 by the corresponding record type.
19316 (Analyze_Subprogram_Body): Undo the previous work.
19317 (Analyze_Procedure_Call): If the call has the form Object.Op, the

19325 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
19326 access to subprograms must be recursive.
19327 (Is_Unchecked_Conversion): Improve the test that recognizes
19328 instantiations of Unchecked_Conversion, and allows them in bodies that
19329 are to be inlined by the front-end. When the body comes from an
19330 instantiation, a reference to Unchecked_Conversion will be an
19331 Expanded_Name, even though the body has not been analyzed yet.

19350 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
19351 in the case where the target type is an anonymous access type of an
19352 object or component (that is, when Is_Local_Anonymous_Access is true).
19353 Prevent the special checks for conversions of access discriminants in
19354 the case where the discriminant belongs to a nonlimited type, since
19355 such discriminants have their accessibility level defined in the same
19356 way as a normal component of an anonymous access type.
19357 (Resolve_Allocator): When an allocator's designated type is a class-wide
19358 type, check that the accessibility level of type given in the
19359 allocator's expression or subtype indication is not statically deeper
19360 than the level of the allocator's access type.

19371 (Resolve_Actuals): Enable full error reporting on view conversions
19372 between unrelated by_reference array types.
19373 The rule for view conversions of arrays with aliased components is
19374 weakened in Ada 2005.
19375 Call to obsolescent subprogram is now considered to be a violation of
19376 pragma Restrictions (No_Obsolescent_Features).
19377 (Check_Direct_Boolean_Operator): If the boolean operation has been
19378 constant-folded, there is nothing to check.
19379 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
19380 check on possible violation of restriction No_Direct_Boolean_Operators
19381 until after expansion of operands, to prevent spurious errors when

19416 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
19417 both bound checks, rather than a conjunction.
19418 (Insert_Valid_Check): If the expression is an actual that is an indexed
19419 component of a bit-packed array, force expansion of the packed element
19420 reference, because it is specifically inhibited elsewhere.

19804 (Get_Type_Reference): For a subtype that is the renaming of an actual in
19805 an instantiation, use the first_subtype to ensure that we don't generate

20386 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
20387 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
20388 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
20389 analyzed if expansion is disabled (which could otherwise cause spurious
20390 error messages if expansion has been disabled due to previous
20391 (unrelated) errors).
20393 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
20394 is disabled, the entity denoted by the argument is the access type
20395 itself, not an underlying record type, so there is no need to go back
20396 to the Corresponding_Remote_Type.

20406 denotes a type in the class.
20407 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
20408 of Name_Generic_Dispatching_Constructor.
20410 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

20426 generic formal subprogram association for an abstract formal subprogram.
20427 Check that the attribute is a primitive stream attribute (and not
20428 a class-wide stream attribute) and then rewrite the attribute name
20429 as the name of the appropriate compiler-generated stream primitive.
20431 2005-03-29 Robert Dewar <dewar@adacore.com>
20433 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

20441 itype whose parent is controlled and not yet frozen, do not create a
20442 freeze node for the itype if expansion is disabled.
20444 2005-03-29 Vincent Celier <celier@adacore.com>
20446 * make.adb (Gnatmake): Don't fail if the main project file is declared
20447 as having no Ada sources. Do not display message "no sources to
20448 compile" in quiet output.
20450 2005-03-29 Doug Rupp <rupp@adacore.com>
20452 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

20468 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
20469 rather than proceed ahead using a junk attribute name.
20471 2005-03-29 Vincent Celier <celier@adacore.com>
20473 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
20475 * prj-part.adb (Parse_Single_Project): Set the location of a project
20476 on its defining identifier, rather than on the reserved word "project".
20478 * prj-proc.adb (Expression): Adapt to the fact that default of external
20479 references may be string expressions, not always literal strings.
20480 (Recursive_Process): Set Display_Name equal to Name
20481 when Location is No_Location, that is when there is no actual file.
20482 Get the Display_Name of the project from the source, when it is not a
20484 (Process): Use the Display_Name in error messages
20486 * prj-strt.adb (External_Reference): Allow default to be string
20487 expressions, not only literal strings.
20489 2005-03-29 Vincent Celier <celier@adacore.com>

20500 equivalent type for a remote access-to-subprogram type, go back to the
20501 original RAS entity when displaying an error message, so the casing is
20502 the original source casing.

20511 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
20512 subtype if code is being pre-analyzed, to prevent un-expanded
20513 references to protected formals, among others.
20514 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
20515 interpretation that can be a call, include the result of the call as a
20516 possible interpretation of the dereference.
20518 * sem_ch5.adb (Process_Bounds): Determine type of range by
20519 pre-analyzing a copy of the original range, and then analyze the range
20520 with the expected type.
20522 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
20523 with an overloaded prefix where not all interpretations yield an
20524 access to subprogram, do not rewrite node as a call.
20525 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
20526 the node as a call once the context identifies the interpretation of
20527 the prefix whose call yields the context type.
20528 (Valid_Conversion): For the case of a conversion between
20529 local access-to-subprogram types, check subtype conformance using
20530 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
20531 detailed error message.

20535 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
20536 indicator, indicate that the formal can never be null.
20537 (Process_Formals): If a formal has a non_null indicator, insert the
20538 resulting subtype immediately before the enclosing subprogram decl,
20539 and not at the beginning of the corresponding declarative part, to
20540 prevent access before elaboration (Ada2005).

20649 to install the visible declarations of the enclosing scope of a
20650 record_type_with_private to establish the proper visibility before
20651 freezing the entity and related subprograms.

20663 explanatory error message (including the name of the missing attribute).
20664 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
20665 subprogram determines whether a default implementation exists for a
20666 given stream attribute.
20667 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
20668 Determine whether to generate a default implementation for each stream
20669 attribute separately, as this depends on the specific attribute.
20671 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
20672 limited extension where a stream attribute is missing for a limited
20673 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

21206 These subprogram have been removed because the attribute
21207 Task_Body_Procedure has been moved to the corresponding task type
21208 or task subtype entity to leave a field free to store the list
21209 of interfaces implemented by a task (for AI-345)
21210 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
21211 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
21212 expression flag Do_Range_Check
21213 (Exception_Junk): Change to Flag7 to accomodate above change
21214 (Box_Present, Default_Name, Specification, Set_Box_Present,
21215 Set_Default_Name, Set_Specification): Expand the expression
21216 "X in N_Formal_Subprogram_Declaration" into the corresponding
21217 two comparisons. Required to use the csinfo tool.
21219 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
21220 "with string" given.
21222 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
21225 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
21228 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
21229 attribute Task_Body_Procedure rather than the old semantic field that
21230 was available in the task_type_declaration node.
21232 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
21233 interface type definitions.
21234 (P_Formal_Derived_Type_Definition): Modified to handle the list of
21237 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
21238 task type declaration.
21239 (P_Protected): Modified to handle the list of interfaces in a
21240 protected type declaration.
21242 2005-03-15 Doug Rupp <rupp@adacore.com>
21243 Vincent Celier <celier@adacore.com>
21245 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
21246 (Gen_Output_File_C): Likewise.
21247 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
21249 2005-03-15 Thomas Quinot <quinot@adacore.com>
21251 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
21252 is an N_Raise_Constraint_Error node, create a new copy of it without
21253 going through a call to Duplicate_Subexpr.

21257 Nicolas Setton <setton@adacore.com>
21258 Ed Schonberg <schonberg@adacore.com>
21264 * decl.c (gnat_to_gnu_field): Reject aliased components with a
21265 representation clause that prescribes a size not equal to the rounded
21266 size of their types.
21267 (gnat_to_gnu_entity, case E_Component): Always look at
21268 Original_Record_Component if Present and not the entity.

21270 of tagged extension types by not making field for components that are
21272 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
21273 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
21274 expression to the type of the object when the object is constant.
21275 Reverse defer_debug_incomplete_list before traversing it, so that trees
21276 are processed in the order at which they were added to the list. This
21277 order is important when using the stabs debug format.
21278 If we are deferring the output of debug information, also defer this
21279 output for a function return type.
21280 When adding fields to a record, prevent emitting debug information
21281 for incomplete records, emit the information only when the record is
21283 (components_to_record): New parameter defer_debug.
21284 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
21285 (gnat_to_gnu_field_decl): New function.
21286 (substitution_list, annotate_rep): Call it.
21287 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
21288 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
21289 No longer update discriminants to not be a COMPONENT_REF.
21290 (copy_alias_set): Strip padding from input type; also handle
21291 unconstrained arrays properly.
21293 * gigi.h (write_record_type_debug_info): New function.
21294 Convert to use ANSI-style prototypes. Remove unused
21295 declarations for emit_stack_check, elab_all_gnat and
21296 set_second_error_entity.
21297 (gnat_to_gnu_field_decl): New decl.
21299 * utils.c (write_record_type_debug_info): New function.

21302 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
21303 (update_pointer_to): Fix pasto.
21304 (convert) <UNION_TYPE>: Accept slight type variations when
21305 converting to an unchecked union type.
21307 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
21308 replace the N_Freeze_Entity with a null statement.
21310 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
21311 within a constrained subcomponent of an enclosing record, place the
21312 freeze nodes in the scope stack entry for the enclosing record.
21313 (Undelay_Type): New Subprogram.
21314 (Set_Small_Size): Pass T, the type to modify; all callers changed.
21315 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
21316 within records; allow them to have freeze nodes if their base types
21319 * exp_util.adb (Remove_Side_Effects): Properly test for
21320 Expansion_Delayed and handle case when it's inside an
21321 N_Qualified_Expression.
21323 * sem_ch3.adb (Derived_Type_Declaration): New predicate
21324 Comes_From_Generic, to recognize accurately that the parent type in a
21325 derived type declaration can be traced back to a formal type, because
21326 it is one or is derived from one, or because its completion is derived
21328 (Constrain_Component_Type): If component comes from source and has no
21329 explicit constraint, no need to constrain in in a subtype of the
21331 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
21332 Minor change to propagate Is_Ada_2005 flag
21334 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
21335 Expansion_Delayed is False.
21336 (assoc_to_constructor): Ignore fields that have a
21337 Corresponding_Discriminant.
21338 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
21339 function returns "by target", dereference the target pointer using the
21340 type of the actual return value.
21341 <all>: Be prepared for a null gnu_result.
21342 (processed_inline_subprograms): Check flag_really_no_inline
21343 instead of flag_no_inline.
21344 (set_second_error_entity): Remove unused function.

21349 2005-03-15 Robert Dewar <dewar@adacore.com>
21350 Ed Schonberg <schonberg@adacore.com>
21351 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
21353 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
21354 Must_Be_Byte_Aligned for cases where we do not need to use a
21355 System.Pack_nn unit.
21357 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
21359 Needed now that we do some processing for IN parameters as well. This
21360 may well fix some unrelated errors.
21361 (Expand_Call): Handle case of unaligned objects (in particular those
21362 that come from packed arrays).
21363 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
21364 renamed entity is an inherited operation, re-expand the call using the
21365 original operation, which is the one to call.
21366 Detect attempt to inline parameterless recursive subprogram.
21367 (Represented_As_Scalar): Fix to work properly with private types
21368 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
21369 accurate estimate. Yields True in far fewer cases than before,
21370 improving the quality of code that depends on this test.
21372 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
21373 over both visible and private declarations to remove them from tree,
21374 and mark subprograms declared in package as eliminated, to prevent
21375 spurious use in subsequent compilation of generic units in the context.
21377 * exp_util.ads: Minor cleanup in variable names
21379 * sem_eval.ads, sem_eval.adb: Minor reformatting
21380 (Compile_Time_Known_Bounds): New function
21382 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21384 * exp_ch7.adb (Convert_View): Use base types of underlying types when
21385 determining whether an unchecked conversion is needed for the argument
21386 of an initialization call.
21388 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21390 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
21391 that appears in the instantiation rather than the internal subtype
21392 generated in the wrapper package, to avoid anomalies in gigi when the
21393 target is derived from a private type whose full view is an access type.
21395 2005-03-15 Robert Dewar <dewar@adacore.com>
21397 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
21399 Add documentation to replace the use of this flag
21400 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
21403 2005-03-15 Thomas Quinot <quinot@adacore.com>
21405 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
21406 here from exp_attr so it can be shared between exp_attr and exp_dist.
21407 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
21408 all TSS names, not a subset thereof, and the previous name introduced
21409 an unnecessarily confusion that a distinction might exist between
21410 "OK" TSS names and some "not OK" TSS names.
21412 2005-03-15 Doug Rupp <rupp@adacore.com>
21414 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
21417 2005-03-15 Pascal Obry <obry@adacore.com>
21418 Eric Botcazou <ebotcazou@adacore.com>
21422 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
21423 when IN_RTS. This is to work around a bootstrap path problem.
21425 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
21426 table and pass it to __gnat_install_SEH_handler().
21427 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
21429 * lang.opt: Fix specification of -fRTS=.
21431 2005-03-15 Doug Rupp <rupp@adacore.com>

21433 Vincent Celier <celier@adacore.com>
21434 Arnaud Charlet <charlet@adacore.com>
21437 This change works fine when gnatlib is built from the gcc directory,
21438 but does not work when using the libada Makefile, since GCC_FOR_TARGET
21439 is not passed to ada/Makefile.in, so more work is needed by a
21440 Makefile/configure expert.
21442 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
21443 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
21444 Setup gnatlink switch -M for x86_64 linux, as it is already setup
21446 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
21447 Run ranlib on libgccprefix.a
21448 Define PREFIX_OBJS for Darwin, to build libgccprefix.
21449 (ADA_INCLUDE_SRCS): Split Ada packages.
21451 2005-03-15 Robert Dewar <dewar@adacore.com>
21453 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
21455 * impunit.adb: Add GNAT.UTF_32
21457 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
21459 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
21460 now uses GNAT.UTF_32).
21462 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
21463 capabilities for categorizing characters using Unicode categories
21465 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21467 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
21468 instantiation that has been rewritten as a package body, retrieve spec
21469 to generate proper name for implicit_with_clause.
21470 (Install_Parents): Recognize a parent that is an instantiation but has
21471 been rewritten as a package declaration during analysis.
21473 2005-03-15 Javier Miranda <miranda@adacore.com>
21474 Ed Schonberg <schonberg@adacore.com>
21476 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
21477 parameter reported some error we immediately return. This improves the
21478 behaviour of the frontend in case of errors.
21479 (Install_Parent, Remove_Parent): Introduce new flag
21480 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
21481 ancestor of a generic child unit, when the child is being instantiated.
21482 (Inline_Instance_Body): If we are compiling the private
21483 part or the body of a child unit, restore the proper visibility of the
21484 parents after compiling the instance body.
21486 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21487 Javier Miranda <miranda@adacore.com>
21490 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
21491 of a private type, in which case it is underlying_type that denotes
21492 the proper task. Also modified to use the new entity attribute
21493 that is directly available in the task type and task subtype entities
21494 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
21495 arrays when other dimensions than the first are constrained by
21496 discriminants of an enclosing record.
21497 (Insert_Explicit_Dereference): If the prefix is an indexed component or
21498 a combination of indexed and selected components, find ultimate entity
21499 and generate the appropriate reference for it, to suppress spurious
21501 (Note_Possible_Modification): If an entity name has no entity, return.
21502 (Is_Variable): A function call never denotes a variable.
21503 (Requires_Transient_Scope): For record types, recurse only on
21504 components, not on internal subtypes that may have been generated for
21505 constrained components.
21507 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21509 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
21510 Eliminated as candidates for resolution. Both efficient, and avoids
21511 anomalies with operators declared in deleted code.
21512 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
21513 expansion is disabled (as when compiling a generic) to prevent spurious
21514 warnings on prefixes of selected components.
21516 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21518 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
21519 attached to a list before checking whether it appears in the private
21520 declarations of the current package.
21521 (Make_Inequality_Operator): Insert declaration in proper declarative
21522 list rather than just setting the Parent field, so that
21523 Is_Private_Declaration can handle it properly.
21525 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21527 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
21528 a renaming a body, check that the renamed subprogram in not intrinsic.
21529 (Find_Direct_Name): If several use_visible entities hide
21530 each other, and the context is a predefined file compiled through
21531 rtsfind, keep only the entity that comes from a predefined file.
21533 2005-03-15 Geert Bosch <bosch@adacore.com>
21535 * s-fatgen.adb (Valid): Extend special exceptions to account for long
21536 long float padding to also cover AMD64 and IA64.
21538 2005-03-15 Gary Dismukes <dismukes@adacore.com>
21540 * s-imgwch.adb: Add with and use of Interfaces.
21541 (Img_Wide_Character): Change type of Val to Unsigned_16.
21542 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
21544 2005-03-15 Matthew Gingell <gingell@adacore.com>
21546 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
21548 2005-03-15 Robert Dewar <dewar@adacore.com>

21552 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
21554 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95

21590 Sergey Rybin <rybin@adacore.com>
21592 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
21593 too specific and long-winded to be appropriate for the GNAT User's
21595 Warn about use of GCC switches not documented in the GNAT User's Guide,
21596 as these may cause generated code to not conform to Ada semantics.
21597 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
21598 Add documentation for -gnat95 and -gnat05 switches
21599 Remove paragraph documenting obsolete way to refer to third party
21601 Add a few references to Ada_05 that were missing.
21602 Update documentation on -gnatZ/-gnatL.

21649 2005-02-12 Richard Henderson <rth@redhat.com>
21651 * utils.c (gnat_type_for_mode): Return NULL for COMPLEX modes;

22018 the formal subprogram.
22019 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,

22044 as the tagged type for the cases of abstract formal subprograms and
22045 renamings of those. Clean up spec comments.

22047 procedure", covering the case of a call to a formal abstract procedure
22048 that has statically tagged operands.

22166 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
22167 unchecked union with no inferable discriminants, return a
22168 Raise_Program_Error node, rather than inserting it at the point the
22170 (Expand_Record_Equality, Component_Equality): Handle properly the case
22171 where some subcomponent is an unchecked union whose generated equality
22172 code raises program error.
22174 2005-02-09 Doug Rupp <rupp@adacore.com>
22176 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.
22177 [VMS] (#define exit hack): Remove.
22179 2005-02-09 Pascal Obry <obry@adacore.com>
22180 Arnaud Charlet <charlet@adacore.com>
22182 * init.c (__gnat_initialize): Add a new parameter eh which contains the
22183 address of the exception registration. The Win32 version of this
22184 routine calls __gnat_install_SEH_handler() to initialize the SEH
22185 (Structured Exception Handling) handler.
22186 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
22187 SEH (Structured Exception Handling) now.
22188 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
22189 (__gnat_initialize for ppc-vxworks): Adjust comments and the
22190 preprocessor condition protecting the call to the extra eh setup
22191 subprogram, which is only available for the ppc target.
22192 (__gnat_clear_exception_count): replaced reference to
22193 variable taskIdCurrent by call to taskIdSelf(), cleaner.
22195 * seh_init.c: New file.
22197 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
22198 (GNATBIND_OBJS): Idem.
22200 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
22201 routine takes a new parameter (a pointer to the exception registration
22202 for the SEH (Structured Exception Handling) support.
22204 * raise.h: (__gnat_install_SEH_handler): New prototype.
22205 Update copyright notice.
22207 * s-tassta.adb (Task_Wrapper): Declare the exception registration
22208 record and initialize it by calling __gnat_install_SEH_handler.
22210 2005-02-09 Vincent Celier <celier@adacore.com>
22212 * make.adb (Gnatmake): Do not fail when the main project has no object
22215 2005-02-09 Doug Rupp <rupp@adacore.com>

22218 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
22219 [VMS]: Add translations for g-enblsp.adb.
22221 * s-asthan-vms.adb: Removed.
22222 * s-asthan-vms-alpha.adb: Added.
22224 2005-02-09 Pascal Obry <obry@adacore.com>
22226 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.
22227 (LIBGNAT_OBJS): Add seh_init.o.
22229 2005-02-09 Arnaud Charlet <charlet@adacore.com>
22232 * Makefile.in: Link all gnat tools with -static-libgcc, since
22233 -shared-libgcc is now used by default on some systems (e.g. linux with
22235 Remove references to Makefile.prolog/generic, no longer used.
22237 2005-02-09 Vincent Celier <celier@adacore.com>
22239 * prj-makr.adb (Process_Directory): Put file name in canonical case
22240 before matching against the patterns.
22241 If gnatname has been invoked as <prefix>-gnatname
22242 then invoke the compiler as <prefix>-gcc, not just "gcc".
22244 2005-02-09 Ed Schonberg <schonberg@adacore.com>
22246 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
22247 with expansion disabled. The actual subtype is needed among other
22248 places when the selected component appears in the context of a loop
22249 bound, and denotes a packed array.
22250 (Operator_Check): Always use the first subtype in the
22251 error message, to avoid the appearance of internal base types.
22252 (Transform_Object_Operation): Copy each actual in full
22253 to the parameter associations of the constructed call, rather than
22254 using the shallow copy mechanism of New_Copy_List. This ensures that
22255 the chaining of named associations is done properly.
22256 (Complete_Object_Operation): Rewrite node, rather than
22257 replacing it, so that we can trace back to the original selected
22260 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
22261 and calls that use object notation, if the called function is not
22262 declared in a withed unit, place the elaboration constraint on the
22263 unit in the context that makes the function accessible.
22264 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
22265 imposes an elaboration constraint between two packages.
22267 2005-02-09 Ed Schonberg <schonberg@adacore.com>
22269 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
22270 views of a private type after handling its private dependents, to
22271 maintain proper stack discipline between entry and exit from the
22274 2005-02-09 Cyrille Comar <comar@adacore.com>
22276 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.
22277 Minor reformatting.

22281 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
22282 fields for foreign threads.
22284 2005-02-09 Doug Rupp <rupp@adacore.com>

22287 recursion warnings when compiled with -gnatdm.
22289 2005-02-09 Robert Dewar <dewar@adacore.com>
22291 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
22292 Slight fix to documentation of -gnaty with no parameters
22294 * xr_tabls.ads: Add ??? comment for missing overall comment
22296 * xsinfo.adb: Make default file name be sinfo.h, since this is what
22297 we now use by default.
22299 * xsnames.adb: Adjust end of file test to look for five space followed
22300 by '#' instead of six spaces. The format of xsnames.adb was modified
22301 in the last update.
22303 * a-numeri.ads: Add reference to AI-388 for greek letter pi
22306 * clean.adb: Minor reformatting.
22308 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
22309 gnatname.adb: Minor reformatting
22310 Add 2005 to copyright output when utility is run
22312 * csets.adb: Eliminate obsolete comment
22314 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
22317 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
22319 2005-02-09 Sergey Rybin <rybin@adacore.com>
22321 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
22322 the difference between compact and incompact layout and add the record
22323 representation clause to the example illustrating different layouts.
22324 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
22325 component clauses").
22327 2005-02-09 Florian Villoing <villoing@adacore.com>
22329 * gnat_ugn.texi: Fix typos.
22330 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
22332 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
22333 in the generated documentation.
22335 2005-02-09 Arnaud Charlet <charlet@adacore.com>
22337 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

22377 * exp_util.ads: Minor correction in comment.
22379 2005-02-09 Arnaud Charlet <charlet@adacore.com>
22381 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
22382 since this procedure is now too complex to be worth inlining.
22384 2005-02-09 Richard Henderson <rth@redhat.com>
22386 * utils.c (gnat_define_builtin): Remove.
22387 (gnat_install_builtins): Use build_common_builtin_nodes.

22629 2005-01-03 Olivier Hainque <hainque@adacore.com>
22631 * decl.c (compatible_signatures_p): New function. The intended purpose
22632 is to check if two function signatures for a call-site and a callee are
22633 compatible enough for the call to be valid. The underlying purpose is
22634 to check if a call to a mapped builtin is using the right interface.

23164 (Remove_Next_Debug): Same fix
23166 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
23167 maintain back pointers now, though we did not used to, and comments
23169 (Prepend): Remove pragma Inline.
23170 (Remove_Next): Same cleanup
23172 2004-12-07 Thomas Quinot <quinot@adacore.com>
23174 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
23175 used to record an implicit dereference as a read operation on its
23176 prefix when operating under -gnatc. Necessary to avoid spurious
23177 'variable assigned but never read' warnings in that mode.
23178 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
23179 is a non-overloaded implicit dereference, call the above subprogram to
23180 ensure proper recording of references.
23182 2004-12-07 Gary Dismukes <dismukes@adacore.com>
23184 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
23185 to be resolved later as part of Analyze_Iteration_Scheme's call to
23188 2004-12-07 Ed Schonberg <schonberg@adacore.com>
23190 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

23200 * g-socket.ads (Get_Host_By_Address, Get_Host_By_Name): Clarify
23201 documentation of the behaviour of these functions when passed an IP
23202 address that has no record in the system hosts database and no reverse

23222 2004-12-07 Vincent Celier <celier@adacore.com>
23223 Sergey Rybin <rybin@adacore.com>
23225 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
23226 Files" with the new tool and package names.
23227 Reformatting to suppress most of the warnings for line too long
23228 Document the new section "Project Search Path:" in the output of
23230 Add gnatmetric section
23232 2004-12-07 Vincent Celier <celier@adacore.com>
23234 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
23235 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
23236 and -eit to -ept. Added qualifier
23237 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
23239 2004-11-27 Andreas Schwab <schwab@suse.de>
23241 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
23243 2004-11-25 Arnaud Charlet <charlet@adacore.com>
23245 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
23246 internal implementation unit GNAT.Sockets.Thin,
23247 as their usage for sockets is non-portable (using the read and write
23248 functions from the system runtime library is fine on UNIX but won't
23249 work under Windows).
23251 * mingw32.h: Update copyright notice.
23253 2004-11-25 Arnaud Charlet <charlet@adacore.com>
23255 * ada-tree.h: Minor reformatting of previous change to avoid lines
23256 longer than 79 characters.

23277 Style_Check_Order_Subprograms.
23279 2004-11-18 Arnaud Charlet <charlet@adacore.com>
23281 * adaint.h, adaint.c
23282 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
23284 Add also a cast to kill another warning.
23285 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
23286 parameter with the priority class of the parent process instead of
23287 always using the NORMAL_PRIORITY_CLASS.
23288 (__gnat_dup): New function.
23289 (__gnat_dup2): New function.
23290 (__gnat_is_symbolic_link): Enable the effective body of this
23291 function when __APPLE__ is defined.
23293 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
23296 2004-11-18 Olivier Hainque <hainque@adacore.com>
23298 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
23299 address of which may be used to represent "others" and "all others"
23300 choices in exception tables, instead of the current harcoded
23301 (void *)0 and (void *)1.
23302 (Setup_Exception): Do nothing in the GNAT SJLJ case.
23304 * gigi.h (others_decl, all_others_decl): New decls representing the
23305 new Others_Value and All_Others_Value objects.
23306 (struct attrib): Rename "arg" component as "args", since GCC expects a
23307 list of arguments in there.
23309 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
23310 corresponding objects exported by a-exexpr, instead of hardcoded dummy
23313 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
23314 others_decl and all_others_decl instead of hardcoded dummy addresses
23315 to represent "others" and "all others" choices, which is cleaner and
23316 more flexible with respect to the possible eh pointer encoding policies.
23318 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
23319 (process_attributes): Account for the naming change of the "args"
23320 attribute list entry component.
23322 * decl.c (build_attr_list): Rename into prepend_attributes to allow
23323 cumulating attributes for different entities into a single list.
23324 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
23325 attributes for the current entity and propagate first subtype
23326 attributes to other subtypes.
23327 <E_Procedure>: Attribute arguments are attr->args and not
23328 attr->arg any more.
23329 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
23330 argument provided, as this is what GCC expects. Use NULL_TREE instead
23333 2004-11-18 Robert Dewar <dewar@adacore.com>
23335 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
23336 Minor reformatting througout (including new function specs)
23337 Add ??? comments asking for clarification.
23339 2004-11-18 Thomas Quinot <quinot@adacore.com>
23341 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
23342 incomplete duplicate implementation of this subprogram from butil.
23344 2004-11-18 Thomas Quinot <quinot@adacore.com>

23350 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
23351 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
23353 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
23355 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
23357 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
23358 distribution subprogram identifiers that are either subprogram numbers

23361 string distribution identifiers assigned to a given subprogram.
23362 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
23363 (Add_RAS_Dereference_TSS): Add comments.
23364 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
23365 is not referenced yet because it will be used by the PolyORB DSA
23367 (Insert_Partition_Check): Remove fossile code.
23368 (First_RCI_Subprogram_Id): Document this constant.
23369 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
23371 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
23372 replaced with calls to Get_Library_Unit_Name_String. Previously there
23373 were several instances of the same code in different locations in the
23374 compiler; this checkin completes the replacement of all of these
23375 instances with calls to a common subprogram.
23376 Minor reformatting.
23378 * sem_dist.adb: Remove comment noting that RPC receiver generation
23379 should be disabled for RACWs that implement RASs.
23380 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

23384 qualified name of a library unit into the name buffer.
23385 (Note_Possible_Modification): Generate a reference only
23386 if the context comes from source.
23388 * snames.ads (PCS_Names): New subtype corresponding to names of
23389 supported implementations of the Partition Communication Subsystem
23390 (PCS) (i.e. the runtime library support modules for the distributed

23404 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
23405 (Expand_Pragma_Psect_Object): New procedure
23406 These procedures contain the revised and cleaned up processing for
23407 these two pragmas. This processing was formerly in Sem_Prag, but
23408 is more appropriately moved here. The cleanup involves making sure
23409 that the pragmas are properly attached to the tree, and that no
23410 nodes are improperly shared.
23412 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
23413 pragmas to Exp_Prag, which is more appropriate.
23414 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
23415 check for duplicates Remove use of Is_Psected flag, no longer needed.
23416 Use new Make_String_Literal function with string.
23418 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
23419 that are functions return universal values, that have to be converted
23420 to the context type.
23421 Use new Make_String_Literal function with string.
23422 (Get_Stream_Convert_Pragma): New function, replaces the use of
23423 Get_Rep_Pragma, which had to be kludged to work in this case.
23425 * freeze.adb: Use new Has_Rep_Pragma function
23427 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
23428 function with string.
23429 Use new Has_Rep_Pragma function.
23431 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
23434 2004-11-18 Robert Dewar <dewar@adacore.com>
23436 * errout.ads, errout.adb: (First_Sloc): New function
23438 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
23439 check (-gnatyx) instead of being included as a redundant construct
23442 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
23443 Style_Check_Order_Subprograms.
23445 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
23446 stylesw.adb: Add Style_Check_Xtra_Parens
23448 * usage.adb: Add line for -gnatyx (check extra parens)
23450 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
23452 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23453 Robert Dewar <dewar@adacore.com>
23455 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
23456 discriminant of a constrained subtype, analyze the copy of the
23457 corresponding constraint, because in some cases it may be only
23458 partially analyzed.
23459 Removes long-lived ??? comments.
23461 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
23462 handled controlled or secondary-stack expressions within the
23463 iteration_scheme of a loop.
23465 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
23466 bounds that may contain functions calls, to prevent memory leaks when
23467 the bound contains a call to a function that uses the secondary stack.
23468 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
23469 generate temporaries for loop bounds that might contain function calls
23470 that require secondary stack and/or finalization actions.
23472 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
23473 selected component and the selector is overloadable (not just a
23474 function) treat as function call, Analyze_Call will disambiguate if
23476 (Analyze_Selected_Component): Do not generate an actual subtype for the
23477 selected component if expansion is disabled. The actual subtype is only
23478 needed for constraint checks.
23479 (Analyze_Allocator): If restriction No_Streams is set, then do
23480 not permit objects to be declared of a stream type, or of a
23481 composite type containing a stream.
23483 * restrict.ads: Remove the a-stream entry from Unit_Array, since
23484 No_Streams no longer prohibits with'ing this package.
23486 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
23487 discriminants, but the parent base has unknown discriminants, there is
23488 no discriminant constraint to inherit. Such a discrepancy can arise
23489 when the actual for a formal type with unknown discriminants is a
23490 similar private type whose full view has discriminants.
23491 (Analyze_Object_Declaration): If restriction No_Streams is set, then
23492 do not permit objects to be declared of a stream type, or of a
23493 composite type containing a stream.
23495 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23497 * exp_dbug.ads: Update documentation to reflect simpler encoding for
23498 protected operations.
23500 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
23501 generated name, it complicates decoding in gdb and hinders debugging
23502 of protected operations.
23503 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
23504 flag for the protected entry barrier function.
23505 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
23506 flag for the protected entry function.

23512 * Makefile.in: Inform the value of the variable GMEM_LIB in the
23513 Darwin-specific section.
23515 * lang-specs.h: Change the placement of the %1 marker.
23516 Works around the fact that gcc adds -fPIC by default under Darwin.
23518 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23520 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
23521 type of the object with the packed array type, set the Analyzed flag
23522 on the object if it is an entity or simple indexed component, to avoid
23523 spurious type errors.
23525 2004-11-18 Gary Dismukes <dismukes@adacore.com>
23527 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
23528 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
23529 separate line from the version message.
23531 2004-11-18 Ed Falis <falis@adacore.com>
23533 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
23535 (init_float): Eliminate initialization of floating point status for
23536 AE653. The instructions have no effect for vThreads.
23538 2004-11-18 Vincent Celier <celier@adacore.com>
23540 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
23541 gnatbind is invoked with -shared.
23543 2004-11-18 Jose Ruiz <ruiz@adacore.com>
23545 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
23546 for Detect_Blocking which is redundant with the check done within the
23547 procedure Protected_Single_Entry_Call.
23548 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
23549 Detect_Blocking which is redundant with the check done within the
23550 procedure Protected_Single_Entry_Call.
23552 2004-11-18 Vincent Celier <celier@adacore.com>
23554 * makegpr.adb (Compile): Put the compiling switches (in package
23555 Compiler and on the command line) immediately after "-c", instead of
23556 at the end of the command line invocation of the compiler, when
23557 compiling a non-Ada file.
23558 (Build_Global_Archive): When there is no need to rebuild the archive,
23559 set Global_Archive_Exists, so that the archive is passed to the linker
23562 2004-11-18 Robert Dewar <dewar@adacore.com>
23563 Sergey Rybin <rybin@adacore.com>
23566 Remove extra paren check from list of checks for redundant constructs
23567 Add documentation of new -gnatyx style check (check extra parens)
23568 Remove paragraph about gnatelim debug options.
23570 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
23571 objects rather than forbidding dependencies on the package Ada.Streams.
23573 * sinfo.ads: Add ??? note that we should document pragmas passed to
23576 * g-expect.ads: Fix a few typos in the comments.
23578 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
23580 * misc.c (gnat_handle_option): Use %< and %> for quoting in
23583 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
23585 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
23587 2004-11-07 Andreas Schwab <schwab@suse.de>
23589 * Makefile.in (install-gnatlib): Remove spurious hyphen.
23591 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
23594 * Makefile.in (darwin): Set soext to .dylib.
23596 2004-10-26 Vincent Celier <celier@gnat.com>
23597 Thomas Quinot <quinot@act-europe.fr>
23599 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
23600 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
23601 there is no use of GNAT.Sockets.Constants.
23602 Remove remaining pragma Import for C_Write
23603 Remove C_Read and C_Write from internal implementation unit
23604 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
23605 the read and write functions from the system runtime library is fine
23606 on UNIX but won't work under Windows).
23608 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
23609 (Check_Selector): Use C_Recv instead of C_Read.
23610 Selectors are the GNAT.Sockets abstraction to perform a select()
23611 call on a set of descriptors. To allow abortion of an ongoing
23612 select operation, some data is written to a dedicated socket that
23613 is always monitored.
23614 Under Windows, the write and read library functions cannot operate
23615 on sockets, so we need to use send and recv instead, which is portable
23616 across all supported platforms.
23618 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
23619 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
23620 (using the read and write functions from the system runtime library is
23621 fine on UNIX but won't work under Windows).
23623 2004-10-26 Nicolas Setton <setton@act-europe.fr>

23629 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
23630 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
23633 * Makefile.in: Add support for building shared libraries under Darwin.
23634 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
23635 the low level EH init subprogram to be called from __gnat_initialize.
23637 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
23638 indicates which options to pass to the archive indexer.
23640 * mlib-utl.adb: Add support for calling ranlib with additional
23641 options. This is needed for instance under Mac OS X.
23642 (Ranlib_Options): New global variable, used to store the potential
23643 options to pass to ranlib.
23644 (Ar): Use Ranlib_Options when spawning ranlib.
23645 (Initialize): Set the value of ranlib option.
23647 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
23649 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
23650 instead of 8K, to reflect the real potential needs for stack-checking
23653 2004-10-26 Pascal Obry <obry@gnat.com>
23655 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
23657 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
23658 Windows only the initial thread stack size can be set so it is good to
23659 start we a low stack size.
23660 The OS will adjust the size as needed.
23662 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
23663 Nicolas Setton <setton@act-europe.fr>
23665 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
23666 "__unix__" instead of "unix".
23667 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
23668 sections were just mistakenly ignored. The former is
23669 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
23670 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
23671 of hpux. This prevents an unwanted definition of the symbol
23672 convert_addresses in adaint.o.
23674 2004-10-26 Gary Dismukes <dismukes@gnat.com>
23676 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
23677 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
23679 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23681 * a-filico.ads, a-filico.adb: fix incorrect header.
23683 2004-10-26 Javier Miranda <miranda@gnat.com>
23685 * a-ststio.ads: Fix typo in identifier
23687 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23689 * sem_ch4.adb: Minor reformatting.
23691 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23693 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
23694 enabled, check the result of unary and binary operations when the
23695 expression is the right-hand side of an assignment.
23697 2004-10-26 Vincent Celier <celier@gnat.com>
23699 * clean.adb (Delete): Do not output warnings when in quiet output and
23700 not in verbose mode.
23701 (Force_Deletions): New Boolean flag, defaulted to False
23702 (Delete): Only delete a file if it is writable, and when
23703 Force_Deletions is True.
23704 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
23705 (Usage): Line for new switch -f
23706 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
23709 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23711 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
23712 JM type only if its size matches that of the wrapper. When a size is
23713 prescribed and the field is not aliased, remove the wrapper of a JM
23714 type only if the size is not greater than that of the packed array.
23715 (gnat_to_gnu_entity): Change the extension of packed array wrappers
23718 2004-10-26 Geert Bosch <bosch@gnat.com>
23720 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
23721 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
23722 (Pred): Implement in terms of Succ.
23724 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23726 * exp_aggr.adb (Safe_Component): An aggregate component that is an
23727 unchecked conversion is safe for in-place use if the expression of the
23728 conversion is safe.
23729 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
23730 be expandable in place even if the aggregate does not come from source.
23731 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
23732 designated object of an allocator in place, rather than building it
23733 first on the stack. The previous scheme forces a full copy of the array,
23734 and may be altogether unsusable if the size of the array is too large
23735 for stack allocation.
23737 2004-10-26 Robert Dewar <dewar@gnat.com>
23739 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
23740 compares if the component is atomic.
23742 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
23743 array assignment if the component type is atomic.
23745 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23746 Eric Botcazou <ebotcazou@act-europe.fr>
23748 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
23749 is aliased and is a by_reference type, do not pass by copy.
23750 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
23751 detect whether the call is in the right side of an assignment or
23752 the expression of an object declaration. Recurse on component
23753 association within aggregates.
23754 Call it in the condition that determines whether the temporary is
23755 necessary for correct stack-checking.
23757 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23759 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
23760 RACW_Type, used in the PolyORB version.
23761 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
23762 version and the GARLIC version.
23764 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
23765 Rename RCI_Info to RCI_Locator for better consistency between the
23766 GARLIC and PolyORB versions of the distributed systems annex.
23767 (DSA_Implementation_Name): This enumeration lists the possible
23768 implementations of the Partition Communication Subsystem for the
23769 Distributed Systems Annex (DSA). The three available implementations
23770 are the dummy stub implementation (No_DSA), and two versions based on
23771 two different distribution runtime libraries: GARLIC and PolyORB. Both
23772 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
23774 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
23777 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
23778 between the GARLIC and PolyORB versions of the distributed systems
23780 Remove RE_Unbounded_Reclaim_Pool since it is unused.
23782 2004-10-26 Gary Dismukes <dismukes@gnat.com>
23784 * gnat1drv.adb: Suppress calling the back end when
23785 Frontend_Layout_On_Target is true.
23787 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23789 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
23790 Set_Read_Only): New subprograms.
23791 These new routines allow the user to set or unset the Owner execute
23792 and Owner write permission flags on a file.
23794 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
23795 GNAT.OS_Lib.Set_Executable instead of rolling our own.
23797 2004-10-26 Matthew Gingell <gingell@gnat.com>
23799 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
23801 2004-10-26 Pascal Obry <obry@gnat.com>
23803 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
23804 memory before the faulting page we properly test the process read
23805 access for this address using appropriate Win32 routine.
23806 (HPUX sections): guard with "__hpux__" instead of "hpux".
23808 2004-10-26 Robert Dewar <dewar@gnat.com>
23810 * lib-xref.adb (Generate_Reference): Don't complain about reference to
23811 entry parameter if pragma Unreferenced set, since we do not properly
23812 handle the case of multiple parameters.
23814 2004-10-26 Vincent Celier <celier@gnat.com>
23816 * prj-env.adb: (Contains_ALI_Files): New Boolean function
23817 (Ada_Objects_Path.Add): For a library project, add to the object path
23818 the library directory only if there is no object directory or if the
23819 library directory contains ALI files.
23820 (Set_Ada_Paths.Add.Recursive_Add): Ditto
23822 2004-10-26 Vincent Celier <celier@gnat.com>
23824 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
23825 extension of library projects.
23827 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
23828 path defaults to ".:<prefix>/lib/gnat".
23829 (Parse): For an extending all project, allow direct import of a project
23830 that is virtually extended.
23832 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
23833 the specified name is directly imported, return its ID. Otherwise, if
23834 an extension of this project is imported, return the ID of the
23837 2004-10-26 Robert Dewar <dewar@gnat.com>
23839 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
23840 (Sub3): New procedure, used by Scaled_Divide
23841 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
23842 correct more than one instance of failure to propagate carries
23844 (Double_Divide): Handle overflow case of largest negative number
23845 divided by minus one.
23847 * s-arit64.ads (Double_Divide): Document that overflow can occur in
23848 the case of a quotient value out of range.
23851 2004-10-26 Robert Dewar <dewar@gnat.com>
23853 * s-bitops.adb (Bit_Eq): Remove redundant check.
23855 * s-bitops.ads: Minor comment updates
23856 Change some occurrences of Address to System.Address
23858 * s-carsi8.ads: Fix minor cut-and-paste error in comments
23860 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23862 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
23863 accessibility check to prefix that is a protected operation.
23865 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23867 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
23868 empty, post message on stub.
23870 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23871 Javier Miranda <miranda@gnat.com>
23873 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
23874 current instance appears within a unit that is directly in the context
23876 Used to determine whether the body of the instance should be analyzed
23877 immediately after its spec, to make its subprogram bodies available
23878 for front-end inlining.
23879 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
23880 constraint is not allowed on the component type (AARM 12.5.3(3))
23882 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23884 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
23885 'Storage_Pool): enhance, document & limit detection of non-sharable
23888 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
23890 * s-pooglo.ads: Add more documentation now that this pool is properly
23893 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23895 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
23896 or protected type with discriminants, do not constrain the
23897 corresponding record type if the subtype declaration has no
23898 discriminant constraints. This can be the case in source code, or in
23899 the subtype declaration created to rename an actual type within an
23902 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23904 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
23905 different kind of stub (possibly wrong name for file), do not check
23907 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
23908 includes call to some function that returns an unconstrained type, do
23911 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23913 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
23914 appear in the code for the main unit. Dependencies among units in the
23915 context of the main unit are established when those other units are
23916 compiled. Otherwise spurious elaboration constraints can generate
23917 incorrect elaboration circularities.
23919 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23920 Ed Schonberg <schonberg@gnat.com>
23922 * sem_util.adb (Is_Aliased_View): Defend against the case where this
23923 subprogram is called with a parameter that is not an object name. This
23924 situation arises for some cases of illegal code, which is diagnosed
23925 later, and in this case it is wrong to call Is_Aliased, as that might
23926 cause a compiler crash.
23927 (Explain_Limited_Type): Refine previous fix to include
23928 inherited components of derived types, to provide complete information.
23930 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
23931 is the prival for a protected object.
23932 It is necessary to mark this entity as a variable, in addition to
23933 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
23934 modified to avoid checking the Aliased flag on entities that are not
23935 objects. (Checking that flag for non-objects is erroneous and could
23936 lead to a compiler crash).
23938 2004-10-26 Robert Dewar <dewar@gnat.com>
23940 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
23941 X_Frac = 0.5, then we know that the number X must be positive.
23942 (Succ): Remove the same redundant test, and also fix the primary test
23943 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
23945 (Decompose): Add fuller comments to spec
23947 2004-10-26 Pascal Obry <obry@gnat.com>
23949 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
23950 validity (process must have read access). Set to 0 in all other cases.
23951 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
23952 violation on Win32.
23953 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
23954 segmentation violation.
23956 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23958 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
23959 whose type is a constructed subtype of an aliased object with an
23960 unconstrained nominal subtype, convert the actual to the constructed
23961 subtype before taking its address.
23963 2004-10-26 Vincent Celier <celier@gnat.com>
23965 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
23966 (Is_Path_Name_Case_Sensitive): New function
23968 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
23969 (Base_Name, Simple_Name, Current_Directory, Compose,
23970 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
23973 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23974 Vasiliy Fofanov <fofanov@act-europe.fr>
23975 Vincent Celier <celier@gnat.com>
23977 * gnat_ugn.texi: Generalize "finding memory problems" section into a
23978 "memory management issues" section and document some of the useful
23979 memory pools provided as part of the GNAT library.
23980 Remove "virtual" from declaration of A::method2 in
23981 the simple example of Ada/C++ mixed system.
23982 Library Projects may be virtually extended: their virtual extensions
23983 are not Library Projects.
23984 Added section on extending project hierarchies.
23986 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
23988 * adaint.c (__gnat_get_libraries_from_registry): Cast value
23990 (__gnat_portable_spawn): Remove const.
23992 * mingw32.h (MAXPATHLEN): Check for previous definition.
23994 2004-10-17 Matthias Klose <doko@debian.org>
23996 * gnatvsn.ads: Set gnat library version to 4.0.
23998 2004-10-05 Vincent Celier <celier@gnat.com>
24000 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
24002 2004-10-04 Laurent Guerby <laurent@guerby.net>
24005 * Makefile.in: Define and use RANLIB_FLAGS.
24007 2004-10-04 Pascal Obry <obry@gnat.com>
24009 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
24010 other x86 platforms).
24012 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
24014 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
24015 in general and triggers stack alignment adjustment for thread entry
24016 points on targets where this is necessary.
24018 2004-10-04 Bernard Banner <banner@gnat.com>
24021 * Makefile.in: Add section for powerpc linux
24022 Add variant i-vxwork-x86.ads
24024 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
24026 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
24028 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
24029 table registration calls when need be. Ensures no reference to the crt
24030 ctors symbol are issued in the SJLJ case, which avoids possible
24031 undefined symbol errors in the case of modules to be statically linked
24034 2004-10-04 Javier Miranda <miranda@gnat.com>
24036 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
24037 in-line the code corresponding to subprogram Analyze_Actuals. In
24038 addition, analyze the actuals only in case of subprogram call.
24040 2004-10-04 Ed Falis <falis@gnat.com>
24042 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
24044 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
24046 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
24047 in the documentation.
24049 2004-10-04 Robert Dewar <dewar@gnat.com>
24051 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
24053 (Analyze_Block_Statement): Add circuitry to detect following dead code
24054 (Check_Unreachable_Code): Handle case of block exit
24056 2004-10-04 Robert Dewar <dewar@gnat.com>
24058 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
24059 (XMatchD): Avoid warning for Logic_Error call
24061 2004-10-04 Robert Dewar <dewar@gnat.com>
24063 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
24064 consider expressions buried within a procedure actual to be an actual.
24065 This caused some blowups with uses of packed slices within a procedure
24068 2004-10-04 Robert Dewar <dewar@gnat.com>
24070 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
24071 longer need to be initialized to zero.
24072 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
24073 initialized to zero.
24075 * checks.adb (Expr_Known_Valid): Packed arrays are now always
24076 considered valid, even if the representation is modular. That's correct
24077 now that we no longer initialize packed modular arrays to zero.
24079 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
24080 suffixes. These are now documented as the only cases in which the
24081 debugger ignores outer records.
24082 Previously, the spec allowed arbitrary suffixes for this purpose.
24083 Change name of LJM to JM for packed array pad records
24084 Create separate section on packed array handling, and add a whole new
24085 set of comments to this section describing the situation with packed
24086 modular types and justification requirements depending on endianness.
24088 2004-10-04 Robert Dewar <dewar@gnat.com>
24090 * a-except.adb: Add a comment for last change
24092 * einfo.ads: Minor spelling correction in comment
24094 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
24096 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
24099 * sem_util.ads: Minor comment update
24101 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24103 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
24104 Inline_Always when in Configurable_Run_Time mode.
24106 * sem_prag.adb (Process_Convention): If entity is an inherited
24107 subprogram, apply convention to parent subprogram if in same scope.
24108 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
24109 when in Configurable_Run_Time mode.
24111 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24113 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
24114 class_wide type after component list has been inherited.
24116 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24118 * sem_ch12.adb (Check_Generic_Actuals): New predicate
24119 Denotes_Previous_Actual, to handle properly the case of a private
24120 actual that is also the component type of a subsequent array actual.
24121 The visibility status of the first actual is not affected when the
24122 second is installed.
24123 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
24124 make fully recursive the treatment of formals of packages declared
24126 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
24127 the above on exit from an instantiation.
24128 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
24129 current instantiation which is now complete.
24130 (Analyze_Package_Instantiation): No instantiated body is needed if the
24131 main unit is generic. Efficient, and avoid anomalies when a instance
24132 appears in a package accessed through rtsfind.
24134 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24136 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
24137 do not generate a declaration for a temporary if the call is part of a
24138 library-level instantiation.
24140 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24142 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
24143 searching for a limited component to flag.
24145 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
24146 expansion of Input, to account for the fact that the implicit call
24147 generated by the attribute reference must freeze the user-defined
24148 stream subprogram. This is only relevant to 'Input, because it can
24149 appear in an object declaration, prior to the body of the subprogram.
24151 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
24152 expansion can proceed and further errors uncovered.
24153 (Minor clean up): Fix cases of using | instead of \ for continuation
24156 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24158 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.

24165 specified alignment before validating size.
24166 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
24167 stripped-down declaration for the type of the inner field when making
24170 * utils.c (finish_record_type): Do not compute the size in units
24171 incrementally. Instead compute it once for the rep clause case.
24172 Use gcc_assert and gcc_unreachable.
24174 2004-10-04 Vincent Celier <celier@gnat.com>
24176 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
24178 (Is_Valid_Path_Name): Take '/' as a directory separator.
24180 2004-10-04 Vincent Celier <celier@gnat.com>
24182 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
24183 (Extended_Project) only if Extended_Project is defined, to avoid
24185 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
24187 (Parse_Single_Project): Ditto.
24189 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
24190 Add_To_Project_Path for virtual projects.
24192 2004-10-04 Vincent Celier <celier@gnat.com>
24194 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

24197 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
24198 parameter Options_2.
24200 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
24201 Build_Dynamic_Library with an empty Options_2.
24203 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no

24207 directory separator, if any.
24208 (Gprmake): Do not allow mains on the command line for library projects.
24209 Do not attempt to link when the project is a library project.
24210 (Library_Opts): New table to store Library_Options.
24211 (Build_Library): If Library_Options is specified, pass these options
24212 when building a shared library.
24214 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
24216 * s-tposen.adb (Service_Entry): The object must be always unlocked at
24217 the end of this procedure now that the unlock operation was inserted
24220 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
24222 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
24223 corresponding to the Preallocated_Stacks flags in System.
24224 (Get_Target_Parameters): Including the processing for

24235 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
24236 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
24237 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
24238 used to signal whether the compiler creates the required stacks and
24239 descriptors for the different tasks (when True) or it is done by the
24240 underlying operating system at run time (when False).
24241 It is initially set to False in all targets.
24243 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
24244 if it is supported by the target.
24245 (Make_Task_Create_Call): Pass the stack address if it has been
24246 previously created. Otherwise pass a Null_Address.
24248 * snames.adb: Add _stack.
24250 * snames.ads: Add Name_uStack. Required to allow the expander to
24251 statically allocated task stacks.
24253 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
24254 Stack_Address argument.
24255 Check that its value is equal to Null_Address because this target does
24256 not support the static stack allocation.

24265 * exp_dist.adb: Split declaration of asynchronous flag out of
24266 Add_RACW_Read_Attribute.
24267 Minor reformatting for better alignment with PolyORB version.
24268 Store the entity for the asynchronous flag of an RACW, rather than the
24269 expression, in the asynchronous flags table. This will allow this flag
24270 to be used in other subprograms beside Add_RACW_Read_Attribute.
24272 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
24274 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

24278 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
24279 sockets constant MSG_NOSIGNAL (Linux-specific).
24280 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
24281 all Send operations.
24282 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
24283 from trigerring SIGPIPE.
24284 Rename components to avoid clash with Ada 2005 possible reserved
24286 (Check_Selector): When the select system call returns with an error
24287 condition, propagate Socket_Error to the caller.

24297 instead do this at freeze time (we won't do it if there is an address
24299 Change "pragma inline" to "pragma Inline" in information and error
24301 Minor reformatting.
24303 * freeze.adb (Check_Address_Clause): Remove previous change, not the
24304 right way of doing things after all.
24305 (Freeze_Entity): For object, set Is_Public for imported entities
24306 unless there is an address clause present.
24308 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
24310 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
24311 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
24312 ensures proper handling of types with rep clauses, which might have
24313 their TYPE_SIZE set already.
24315 2004-09-21 Robert Dewar <dewar@gnat.com>
24317 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
24318 packed array types in both little- and big-endian cases. This change
24319 ensures that we no longer count on the unused bits being initialized
24320 for such types (and in particular ensures that equality testing will
24321 only read the relevant bits).
24322 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
24323 These changes mean that we no longer need to initialize small packed
24325 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
24326 optimization to an LJM field as to its parent field.
24328 * ada-tree.h, trans.c, utils.c, utils2.c:
24329 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
24331 2004-09-20 Jan Hubicka <jh@suse.cz>
24333 * utils.c (gnat_finalize): Remove.
24334 (end_subprog_body): Directly call cgraph_finalize_function;
24335 do not lower the nested functions.
24337 2004-09-20 Robert Dewar <dewar@gnat.com>
24340 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
24341 if an address clause is present, since that means that the Import
24344 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
24346 * 5tsystem.ads: Removed, no longer used.
24348 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
24349 Zack Weinberg <zack@codesourcery.com>
24351 * ada-tree.def: Use tree_code_class enumeration constants
24352 instead of code letters.

24370 an existing directory.
24371 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
24372 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
24373 Convert the result to File_Size.
24375 * prj.ads: (Project_Error): New exception
24377 * prj-attr.adb: Except in procedure Initialize, Fail comes from
24378 Prj.Com, not from Osint.
24379 (Attrs, Package_Attributes): Tables moved to private part of spec
24380 (Add_Attribute, Add_Unknown_Package): Moved to new child package
24382 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
24383 Prj.Project_Error after call to Fail.
24384 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
24385 Fail. Check that package name is not already in use.
24387 * prj-attr.ads: Comment updates to indicate that all subprograms may be
24388 used by tools, not only by the project manager, and to indicate that
24389 exception Prj.Prj_Error may be raised in case of problem.
24390 (Add_Unknown_Package, Add_Attribute): Moved to new child package
24392 (Attrs, Package_Attributes): Table instantiations moved from the body to
24393 the private part to be accessible from Prj.Attr.PM body.
24395 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
24396 from new package Prj.Attr.PM.
24397 (Parse_Attribute_Declaration): Call Add_Attribute from new package
24400 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
24402 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
24403 instead of Elaboration_Checks).

24448 pragmas recognized by GNAT.
24450 * gnat_rm.texi: Document pragma Detect_Blocking.
24452 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
24453 raise Program_Error if called from a protected operation.
24455 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
24456 the protected action nesting level.
24457 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
24458 protected action nesting level.
24459 (Unlock): When pragma Detect_Blocking is active decrease the protected
24460 action nesting level.
24462 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
24463 Protected_Action_Nesting.
24465 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
24466 Common_ATCB record. It contains the dynamic level of protected action
24467 nesting for each task. It is needed for checking whether potentially
24468 blocking operations are called from protected operations.
24469 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
24470 Detect_Blocking is active or not in the partition.
24472 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

24484 the protected action nesting level.
24485 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
24486 Program_Error if called from a protected operation, and increase the
24487 protected action nesting level.

24493 the protected action nesting level.
24494 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
24495 Program_Error if called from a protected operation, and increase the
24496 protected action nesting level.

24502 protected action nesting level.
24504 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
24505 insertion of the statement raising Program_Error. The run time
24506 contains the required machinery for handling that.
24508 * sem_util.ads: Change comment associated to procedure
24509 Check_Potentially_Blocking_Operation.
24510 This procedure does not insert a call for raising the exception because
24511 that is currently done by the run time.
24513 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
24515 * init.c: Add the global variable __gl_detect_blocking that indicates
24516 whether pragma Detect_Blocking is active (1) or not (0). Needed for
24517 making the pragma available at run time.
24518 (__gnat_set_globals): Pass and update the detect_blocking parameter.
24520 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
24521 pragma Detect_Blocking is active.
24523 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
24525 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
24526 DB is found in the ali file. Any unit compiled with pragma
24527 Detect_Blocking active forces its effect in the whole partition.
24529 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
24530 Detect_Blocking is active and delay is called from a protected
24533 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
24534 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
24535 Detect_Blocking is active (0 otherwise).
24536 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
24537 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
24540 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
24542 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
24543 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
24546 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
24547 (Register_Receiving_Stub): Add Subp_Info formal parameter.
24548 Update API in placeholder implemetation of s-parint to reflect changes
24549 in distribution runtime library.
24551 * sem_ch3.adb (Expand_Derived_Record): Rename to
24552 Expand_Record_Extension.
24554 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
24555 primitive operations of potentially distributed object types that have
24556 non-controlling anonymous access formals.
24558 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
24560 New implementation of expansion for remote access-to-subprogram types,
24561 based on the RACW infrastructure.
24562 This version of sem_dist is compatible with PolyORB/DSA as well as
24565 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
24566 Asynchrronous that applies to a remote access-to-subprogram type, mark
24567 the underlying RACW type as asynchronous.
24569 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
24570 __gnat_using_gnu_linker to 1.
24572 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
24573 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
24574 GNAT.Perfect_Hash_Generators, and remove the empty

24579 * exp_ch3.adb (Expand_Derived_Record): Rename to
24580 Expand_Record_Extension.
24581 (Build_Record_Init_Proc.Build_Assignment): The default expression in
24582 a component declaration must remain attached at that point in the
24583 tree so New_Copy_Tree copies it if the enclosing record type is derived.
24584 It is therefore necessary to take a copy of the expression when building
24585 the corresponding assignment statement in the init proc.
24586 As a side effect, in the case of a derived record type, we now see the
24587 original expression, without any rewriting that could have occurred
24588 during expansion of the ancestor type's init proc, and we do not need
24589 to go back to Original_Node.
24591 * exp_ch3.ads (Expand_Derived_Record): Rename to
24592 Expand_Record_Extension.
24594 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
24595 Returns the RACW type used to implement a remote access-to-subprogram
24597 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
24598 New subprograms. Used to create a proxy tagged object for a remote
24599 subprogram. The proxy object is used as the designated object
24600 for RAS values on the same partition (unless All_Calls_Remote applies).
24601 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
24602 System.Partition_Interface.Get_Unique_Remote_Pointer.
24603 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
24604 Renamed from Add_RAS_*_Attribute.
24605 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
24607 New implementation of expansion for remote access-to-subprogram types,
24608 based on the RACW infrastructure.
24610 * exp_dist.ads (Copy_Specification): Update comment to note that this
24611 function can copy the specification from either a subprogram
24612 specification or an access-to-subprogram type definition.
24614 2004-09-09 Ed Schonberg <schonberg@gnat.com>
24616 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
24617 in an instance, between an explicit subprogram an one inherited from a
24618 type derived from an actual.
24620 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
24621 add a polling call if the subprogram is to be inlined by the back-end,
24622 to avoid repeated calls with multiple inlinings.
24624 * checks.adb (Apply_Alignment_Check): If the expression in the address
24625 clause is a call whose name is not a static entity (e.g. a dispatching
24626 call), treat as dynamic.
24628 2004-09-09 Robert Dewar <dewar@gnat.com>
24630 * g-trasym.ads: Minor reformatting
24632 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
24633 packed arrays, since unused bits are expected to be zero for a
24636 2004-09-09 Eric Botcazou <ebotcazou@act-europe.fr>
24638 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
24641 2004-09-09 Pascal Obry <obry@gnat.com>
24643 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
24644 enable map file generation. Add the right option to generate the map
24645 file if Map_File is set to True.
24647 * gnatdll.adb (Gen_Map_File): New variable.
24648 (Syntax): Add info about new -m (Map_File) option.

24902 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
24903 discriminants that rename those of the parent, recover names of
24904 original discriminants for the constraint on the full view of the

24935 returning C.int, to avoid using a derived boolean type.
24937 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

24966 ignore overflows on low and high bounds of an index to also account for
24967 differences in signedness between sizetype and gnu_index_subtype.
24968 These are as legitimate as the ones caused by a lower TYPE_PRECISION

28885 complete assignment subtree which is now unnecessary, as the expansion
28886 of inlined call has been improved to preserve a consistent assignment
28887 tree. Note_Possible_Modification must be called only
28888 after checks have been applied, or else unnecessary checks will
28891 * sem_util.adb (Note_Possible_Modification): Reorganise the handling

29082 part has been scanned-out and it was present
29084 * par-ch3.adb, par-ch4.adb, par-ch6.adb: Give support to AI-231
29086 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
29087 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
29088 type to force the corresponding run-time check
29089 (Resolve_Aggregate): Propagate the null-excluding attribute to the array
29091 (Resolve_Array_Aggregate): Carry out some static checks
29092 (Resolve_Record_Aggregate.Get_Value): Carry out some static check
29094 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null

29145 * sem_ch12.adb: Add comment for previous change
29147 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
29149 * osint.adb (Executable_Prefix): Set Exec_Name to the current
29150 executable name when not initialized. Otherwise, use its current value.
29152 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
29153 initialize it to another executable name than the current one. This
29154 allows to configure paths for an executable name (gnatmake) different
29155 from the current one (gnatdist).
29157 2004-03-29 Ed Schonberg <schonberg@gnat.com>
29159 * exp_ch6.adb (Expand_Call): A call to a function declared in the
29160 current unit cannot be inlined if it appears in the body of a withed
29161 unit, to avoid order of elaboration problems in gigi.
29163 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
29164 information for protected (wrapper) operation as well, to simplify gdb
29167 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
29168 protected body, indicate that the entity for the generated spec comes
29169 from source, to ensure that references are properly generated for it.
29170 (Build_Body_To_Inline): Do not inline a function that returns a
29173 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
29174 apply convention to homonyms that are declared explicitly.
29176 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
29177 that renames an equality operator and the operands are overloaded,
29178 resolve them with the declared formal types, before rewriting as an
29181 2004-03-29 GNAT Script <nobody@gnat.com>
29183 * Make-lang.in: Makefile automatically updated
29185 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>

29204 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
29206 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
29207 attribute reference does not denote a subtype, it can be any
29208 expression that has a classwide type, potentially after an implicit
29209 dereference. In particular, the prefix can be a view conversion for
29210 a classwide type (for which Is_Object_Reference holds), but it can
29211 also be a value conversion for an access-to-classwide type. In the
29212 latter case, there is an implicit dereference, and the original node
29213 for the prefix does not verify Is_Object_Reference.
29215 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
29216 conversion of a discriminant-dependent component of a mutable object
29219 2004-03-25 Ed Schonberg <schonberg@gnat.com>
29221 * freeze.adb (Freeze_Entity): When an inherited subprogram is
29222 inherited, has convention C, and has unconstrained array parameters,
29223 place the corresponding warning on the derived type declaration rather
29224 than the original subprogram.
29226 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
29227 indication on renaming declaration, if formal has a box and actual
29230 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
29231 determine whether to generate an implicit or explicit reference to
29232 the renamed entity.
29234 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
29235 subprogram renaming comes from a defaulted formal subprogram in an
29238 2004-03-25 Gary Dismukes <dismukes@gnat.com>
29240 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
29241 value expressions to ensure that calls within a component definition
29242 will be checked (since those are evaluated during the record type's
29245 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
29247 * s-tpobop.adb: Code clean up:
29248 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

29267 Has_RACW, Is_Generic, etc.)
29268 (Output_Object, Gnatls): Take into account ALI files not attached to
29271 2004-03-22 Vincent Celier <celier@gnat.com>
29273 * gprep.adb: Change all String_Access to Name_Id
29274 (Is_ASCII_Letter): new function
29275 (Double_File_Name_Buffer): New procedure
29276 (Preprocess_Infile_Name): New procedure

29286 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
29288 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
29289 case when the source contains only comments.
29291 2004-03-22 Ed Schonberg <schonberg@gnat.com>
29293 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
29294 declaration for a child subprogram body that acts as a spec, indicate
29295 that the entity in the declaration needs debugging information.
29297 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
29298 full view if the subtype is created for a constrained record component;
29299 gigi has enough information to construct the record, and there is no
29300 place in the tree for the declaration.
29302 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
29303 serial number for the dummy body that is built for analysis, to avoid
29304 inconsistencies in the generation of internal names when compiling
29307 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
29309 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
29312 2004-03-22 GNAT Script <nobody@gnat.com>

29334 * gnat_ug.texi: Add info directory category and entry.
29335 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
29336 gnat_ug_wnt.texi: Regenerate.
29338 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
29340 * ada-tree.h: Update copyright notice.
29341 Minor reformatting.
29343 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
29345 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
29346 as regular exception objects and not as mere integers representing the
29347 condition code. The latter approach required some dynamics to mask off
29348 severity bits, which did not fit well into the GCC table based model.
29349 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
29350 exception data objects. We don't it and it would conflict with the other
29351 external symbol we have to generate for such exceptions.
29353 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
29354 the special code for VMS exceptions, since these are now represented
29355 as regular exceptions objects.
29357 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29359 * decl.c (debug_no_type_hash): Remove.
29360 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
29361 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
29363 2004-03-19 Laurent Guerby <laurent@guerby.net>
29365 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
29366 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
29368 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29370 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
29371 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
29372 (TYPE_RM_SIZE_INT): Directly use type.values.
29373 (TREE_LOOP_ID): Clean up check.
29374 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
29375 TYPE_VALUES, not TYPE_FIELDS.

29384 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
29385 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
29386 Specific.Set instead of direct call to e.g pthread_setspecific.
29388 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
29390 * adaint.c: Update comments.
29392 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
29393 GNATLIB_SHARED for FreeBSD.
29395 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
29397 * init.c [VxWorks]: Do not fix the stack size for the environment task.
29398 When needed (stack checking) the stack size is retrieved
29399 from the VxWorks kernel.
29401 * Makefile.in: Flag -nostdinc is required when building the run time
29402 for avoiding looking for files in the base compiler.
29403 Add the VxWorks specific version of the package body for
29404 System.Stack_checking.Operations (5zstchop.adb).
29406 * Make-lang.in: Add the object file for
29407 System.Stack_Checking.Operations.
29409 * Makefile.rtl: Add object file for the package
29410 System.Stack_Checking.Operations.
29412 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
29414 * s-stache.ads, s-stache.adb: Move the operations related to stack
29415 checking from this package to package System.Stack_Checking.Operations.
29416 This way, stack checking operations are only linked in the final
29417 executable when using the -fstack-check flag.
29419 2004-03-18 Doug Rupp <rupp@gnat.com>
29421 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
29424 * 5qsystem.ads, 5xcrtl.ads: New files.

29430 * prj-env.adb (Source_Paths, Object_Paths): New tables.
29431 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
29432 the procedures Add_To_Path_File.
29433 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
29434 making sure that each directory is present only once and, for object
29435 dirs, when a directory already present is added, the duplicate is
29436 removed and the directory is always put as the last in the table.
29437 Write the path files at the end of these accumulations.
29439 * prj-nmsc.adb (Record_Source): Add source file name in hash table
29440 Files_Htable for all sources.
29442 * prj-proc.adb (Process): Remove restrictions between not directly
29443 related extending projects.
29445 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

29451 parameter Trusted_Mode.
29453 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
29455 * scn.adb (Determine_License): Take into account a degenerated case
29456 when the source contains only comments.
29458 2004-03-18 Ed Schonberg <schonberg@gnat.com>
29460 * sem_warn.adb (Check_References): For a warning on a selected
29461 component that does not come from source, locate an uninitialized
29462 component of the record type to produce a more precise error message.
29464 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
29466 * 3zsoccon.ads: Fix multicast options.
29468 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
29471 2004-03-15 Robert Dewar <dewar@gnat.com>
29473 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
29474 pragma used for a private type.
29476 * lib-xref.adb (Generate_Reference): Do not generate warning if
29477 reference is in a different unit from the pragma Unreferenced.
29479 * 5vtpopde.adb: Minor reformatting
29480 Fix casing of To_Task_ID
29482 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
29483 flag if we have an unchecked conversion to an access type in the same
29486 2004-03-15 Geert Bosch <bosch@gnat.com>
29488 * a-ngcoty.adb (Modulus): In alternate formula for large real or
29489 imaginary parts, use Double precision throughout.
29491 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
29492 we want to be able to compile run-time with -gnata for testing, but
29493 this may also be instantiated in user code that is compiled with -gnata.
29495 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
29497 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
29498 codes. Having a separate type for this is useful to enforce consistency
29499 throughout the various run-time units.
29500 (Exception_Data): Use Exception_Code for Import_Code.
29502 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
29503 Natural and Integer in various places.
29504 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
29505 with the severity bits masked off.
29506 (Register_VMS_Exception): Handle the additional exception data pointer
29509 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
29510 component, now reflected by an exported accessor.
29511 (is_handled_by): New routine to compute whether the propagated
29512 occurrence matches some handler choice specification. Extracted out of
29513 get_action_description_for, and expanded to take care of the VMS
29515 (get_action_description_for): Use is_handled_by instead of an explicit
29516 complex condition to decide if the current choice at hand catches the
29517 propagated occurrence.
29519 * raise.h (Exception_Code): New type for C.
29521 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
29522 System.Standard_Library.Exception_Code, to allow references from the
29523 pragma import/export expander.
29525 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
29526 New accessors to allow easy access to GNAT exception data
29528 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
29529 redundant Handled_By_Others component, helper for the personality
29530 routine which will now be able to call the appropriate exception data
29533 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
29534 component of Standard_Exception_Type to be the closest possible to
29535 Exception_Code in System.Standard_Library, that we cannot get at this
29536 point. Expand a ??? comment to notify that this type node should
29537 probably be rewritten later on.
29539 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
29540 registration call to include a pointer to the exception object in the
29543 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
29544 instead of int and explicit bitmasks.
29546 2004-03-15 Vincent Celier <celier@gnat.com>

30539 checks for bitfield creation are triggered.
30540 (finish_record_type): During last pass over the fields, clear
30541 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

30591 error when there are unusual characters (such as '!') in the paths.
30593 * Makefile.generic: When there are sources in Ada and the main is in
30594 C/C++, invoke gnatmake with -B, instead of -z.

31000 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
31001 N_String_Literal node always references an E_String_Literal_Subtype
31002 entity. This may not be true in the future.
31003 (Possible_Bit_Aligned_Component): Move processing of
31004 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
31006 * exp_ch6.adb (Expand_Thread_Body): Pick up

31011 (Type_May_Have_Bit_Aligned_Components): New function.

31051 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
31052 ineffective elaborate all pragmas on non-visible packages (this
31053 happened when a renamed subprogram was called). Now the elaborate all
31054 always goes on the package containing the renaming rather than the one
31055 containing the renamed subprogram.
31057 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
31058 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

31084 -B is specified. Fail when there are only foreign mains in attribute

31117 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
31119 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve

31275 to __gnat_map_signal, imported from init.c to support
31276 signal -> exception mappings that depend on the vxWorks version.
31279 Created and exported __gnat_map_signal to support signal -> exception
31280 mapping that is dependent on the VxWorks version.

31311 2003-12-11 Ed Schonberg <schonberg@gnat.com>
31313 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
31314 bounds of a loop, create a separate block in order to generate proper
31315 cleanup actions to prevent memory leaks.
31317 * sem_res.adb (Resolve_Call): After a call to
31318 Establish_Transient_Scope, the call may be rewritten and relocated, in

31337 2003-12-08 Robert Dewar <dewar@gnat.com>
31339 * 7sintman.adb: Minor reformatting
31341 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
31342 standard linker options to get standard libraries linked. We now plan
31343 to provide dummy versions of these libraries to match the appropriate
31344 configurable run-time (e.g. if a library is not needed at all, provide
31345 a dummy empty library).
31347 * targparm.ads: Configurable_Run_Time mode no longer affects linker
31348 options (-L parameters and standard libraries). What we plan to do is
31349 to provide dummy libraries where the libraries are not required.
31351 * gnatbind.adb: Minor comment improvement
31353 2003-12-08 Javier Miranda <miranda@gnat.com>
31355 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
31356 aggregate in the parent. Otherwise constants with limited aggregates

31359 default initialized components.
31360 (Gen_Assign): In case of default-initialized component, generate a
31361 call to the IP subprogram associated with the component.
31362 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
31363 of aggregate with default initialized components.
31364 (Has_Default_Init_Comps): Improve implementation to recursively check
31365 all the present expressions.
31367 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
31368 to indicate that the initialization call corresponds to a
31369 default-initialized component of an aggregate.
31370 In case of default initialized aggregate with tasks this parameter is
31371 used to generate a null string (this is just a workaround that must be
31372 improved later). In case of discriminants, this parameter is used to
31373 generate a selected component node that gives access to the discriminant
31376 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
31377 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
31378 allocated aggregates with default-initialized components.
31380 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
31381 the box notation is used in positional aggregates.

31423 Process nodes N_Comment.
31425 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
31426 without comments and there are some comments, set the flag
31427 Unkept_Comments to True.
31428 (Scan): If there are comments, set the flag Unkept_Comments to True and
31429 clear the comments.

31459 Comment_Id and set Token to Tok_Comment when scanning a comment.
31460 (Set_Comment_As_Token): New procedure
31462 * sinput-p.adb: Update Copyright notice
31463 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

31468 * sem_aggr.adb: Add dependence on Exp_Tss package
31469 Correct typo in comment
31470 (Resolve_Aggregate): In case of array aggregates set the estimated
31471 type of the aggregate before calling resolve. This is needed to know
31472 the name of the corresponding IP in case of limited array aggregates.
31473 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
31474 in case of default initialized array components.
31476 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

31496 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
31497 they are automatically generated by Make-lang.in and cause nothing but
31498 maintenance troubles.
31500 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
31502 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

31516 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
31517 to ensure that the kernel fills in the interrupted context structure
31518 before calling a signal handler, which is necessary to be able to
31519 unwind past it. Update the copyright notice.
31521 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
31523 * a-elchha.ads: New file.
31525 * a-elchha.adb: New default last chance handler. Contents taken from

31607 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
31608 included in HIE_NONE_TARGET_PAIRS.
31610 2003-12-03 Ed Schonberg <schonberg@gnat.com>
31613 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
31614 is legal in an instance, because legality is cheched in the template.
31617 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
31618 appplied to an unchecked conversion of a formal parameter.
31621 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

31635 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
31636 so that the debugger can reliably access the value of the parameter,
31637 and therefore is able to display the exception name when an exception
31638 breakpoint is reached.

32977 Remove the test against being in No_Run_Time_Mode before generating a
32978 call to Register_Tag. It is redundant with the test against the
32979 availability of the function Register_Tag.

32995 information, check that the source exists and, if it does, that the path

35186 (general) Add @./@: where approriate, and two spaces after the
35187 full stop at the end of a sentence. Use @samp markup when
35188 referring concrete lexical entities (keywords, attribute names
35189 etc.), and @syntax for ARM grammar elements. Use @r for English

35268 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
35269 need to force universal inlining for these cases.
35271 2001-12-19 Arnaud Charlet <charlet@gnat.com>
35273 * s-taprob.adb: Minor clean ups so that this unit can be used in

35574 2001-12-17 Laurent Pautet <pautet@gnat.com>
35577 Fix comment of Shutdown_Socket and Close_Socket. These functions
35578 should not fail silently because if they are called twice, this
35579 probably means that there is a race condition in the user program.
35580 Anyway, this behaviour is consistent with the rest of this unit.
35581 When an error occurs, an exception is raised with the error message
35582 as exception message.

36916 instead of the previous simple checksum algorithm.
36917 (Time_Stamp_Mismatch): use CRC_Match for comparison.
36918 (Set_Source_Table): idem.
36921 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
36922 instead of simple checksum.
36923 (CRC_Match): new function.
36924 (CRC_Error): new constant.
36926 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
36927 a CRC now and not a simple checksum. A CRC uses lower-case hex
36928 letters, fixes ambiguity in parsing.
36930 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
36931 is what this variable will store.
36933 * bcheck.adb: Change reference to chechsum in comments by CRC.
36934 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
36935 rename All_Checksum_Match to All_CRC_Match. Change due to API
36936 renaming since now GNAT does not use a simple checksum but a
36937 CRC using GNAT.CRC32.
36939 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
36940 now and not anymore a simple checksum.
36942 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
36945 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
36948 (Restore_Scan_State): rename Checksum to CRC.

36953 (Checksum): rename to CRC.
36954 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
36956 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
36957 GNAT.CRC32). Update copyright notice.
36959 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
36960 GNAT.CRC32). Update copyright notice.
36963 (Accumulate_Checksum): removed.
36964 (Update): new procedure. Add a wide-character into the CRC.
36967 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
36968 (Load_File): fix initialization of S (change Source_Checksum to
36971 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
36972 Source_CRC in S initialization.
36974 * sinput.adb (Source_Checksum): renamed to Source_CRC.
36976 * sinput.ads (Source_Checksum): renamed to Source_CRC.
36977 Update comments for the CRC.
36979 * types.adb (Hex): Use lowercase for the letter part.
36981 * types.ads (Get_Hex_String): Returns the hexadecimal representation
36982 for a word. This is currently used only for CRC. In previous version,
36983 the checksum was using a representation with all letter being
36984 upper-case. With the new implementation (using CRC) we do not remove
36985 the 32th bit of the CRC, so we can have an upper-case starting letter
36986 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
36987 It is ambigous since the CRC was optional and could be followed by
36988 options like EB, EE. So now this routines uses lower-case letter for
36989 the hexadecimal representation. Strange enough only lower case letters
36990 where checked in Scan_ALI (even if this was not a possible case).
36992 * gnatvsn.ads (Library_Version): changed to 3.15a.
36994 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
36997 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
37000 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
37001 Add 2001 to copyright notice
37002 (Accumulate_Checksum): Modify to use System.CRC32.
37004 * ali-util.ads: Redo changes of previous revision to continue to use
37005 the word Checksum. Add 2001 to copyright notice.
37007 * ali.adb: Undo some of previous changes, not needed.
37008 Keep the change for lower case letters in the checksum.
37010 * ali.ads: Undo previous change not needed.
37012 * bcheck.adb: Undo most of previous change, not needed.
37013 But do use Checksums_Match for checksum comparison.
37015 * gnatls.adb: Undo most of previous change, not needed.
37016 But do use Checksums_Match for comparing checksums.
37018 * lib-load.adb: Undo previous change, not needed.
37020 * lib-writ.adb: Undo previous change, not needed.
37022 * lib-writ.ads: Document that checksums use lower case,

37027 * scans.ads: Undo previous change, not needed.
37029 * scn-nlit.adb: Undo previous changes, not needed.
37031 * scn-slit.adb: Undo previous change, not needed. Fix header format.

37038 * sinput-p.adb: Undo previous change, not needed.
37040 * sinput.adb: Undo previous change, not needed.
37042 * sinput-l.adb: Undo previous change, not needed.
37044 * sinput.ads: Undo previous change, not needed. Keep only comment
37045 on new checksum algorithm
37047 * Makefile.in: Add s-crc32 as needed, remove g-crc32.
37048 Also remove a-tags and a-stream from GNAT sources.
37050 * ali.adb (Scan_ALI): fix typo introduce in latest check-in.
37052 * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
