2183 WITH clause on a private sibling.
2184 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
2185 child unit is a renaming, create an implicit with_clause on that

2285 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
2286 requeue statement is dispatching. Do not emit an error when the name is

2288 perform subtype conformance between the formals of the current entry
2289 and those of the target interface primitive.
2290 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
2291 Timed_Entry_Call): Analyze the triggering statement as the first step of
2292 the processing. If this is a dispatching select, postpone the analysis
2293 of all select statements until the Expander transforms the select. This

2295 replicated some of the select statements. In case the Expander is
2296 disabled, perform regular analysis.
2297 (Check_Triggering_Statement): New routine.
2298 (Analyze_Requeue): Exclude any interpretations that are not entries when
2299 checking overloaded names in a requeue. Also test type conformance for

2308 for the defaulted actual.
2310 2007-12-13 Geert Bosch <bosch@adacore.com>
2312 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

2916 that handles use of 'Access and 'Unchecked_Access applied to

2962 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
2963 used by VxWorks targets to have access to task-specific data and be
2964 able to extract the stack boundaries for stack checking.
2965 Use system-vms-ia64.ads on ivms.
2967 * Make-lang.in: Update dependencies.
2969 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
2972 2007-10-15 Vincent Celier <celier@adacore.com>

2988 Runtime_Library_Dir.
2990 * prj-part.adb (Parse_Single_Project): Do not check the name of the
2991 config project against the user project names.

3006 2007-10-15 Gary Dismukes <dismukes@adacore.com>
3008 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
3009 association for an access component, add an association with null as
3010 the expression. Remove testing for array subtypes and the setting in
3011 that case of Ctyp to the array component type, which prevented proper
3012 inclusion of an association for null-initialized arrays. Collapse
3013 condition that tests for array subtypes into just a test of
3014 Is_Partially_Initialized_Type (which already covers arrays anyway).
3016 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

3031 * sem_ch4.adb: Minor code and comment reformatting.
3032 (Analyze_Allocator): When the designated type of an unconstrained
3033 allocator is a record with unknown discriminants or an array with
3034 unknown range bounds, emit a detailed error message depending on the
3035 compilation mode and whether the designated type is limited.

3158 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
3160 Mapped location support
3161 * back_end.adb (Call_Back_End): Pass information about source
3162 files instead of units to gigi.
3163 * gigi.h (struct File_Info_Type): New.
3164 (gigi): Rename and change type of number_units parameter, change
3165 type of file_info_ptr parameter.
3166 * trans.c (number_files): New global variable.
3167 (gigi): Rename and change type of number_units parameter, change
3168 type of file_info_ptr parameter.
3169 If mapped location support is enabled, create the isomorphic mapping
3170 between source files and line maps.
3171 (Sloc_to_locus): If mapped location support is enabled, translate
3172 source location into mapped location.
3173 (annotate_with_node): Rename into set_expr_location_from_node.

3199 * a-calend-vms.adb, a-calend.adb:
3200 Add a section on leap seconds control along with two entities used to
3201 enable and disable leap seconds support. The array Leap_Second_Times is
3202 now constant and contains hard time values pre-generated. Remove
3203 all elaboration code used to populate the table of leap seconds.
3206 Add entity Leap_Seconds_Support to the list of global run-time variables
3207 along with a comment on its usage and values.
3208 (Gen_Adainit_Ada): Add code to generate the declaration and import of
3209 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
3210 or one (enabled) depending on the presence of binder switch "-y".
3211 (Gen_Adainit_C): Add code to generate the declaration of external int
3212 __gl_leap_seconds_support. Set is value to zero (disabled) or one
3213 (enabled) depending on the presence of binder switch "-y".

3222 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
3223 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
3225 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
3227 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
3228 function which can be called by the debugger to interrupt the tasks of
3229 an Ada application asynchronously, as needed on VxWorks.
3230 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
3232 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
3233 renamed from Stop_All_Tasks. Update comments.
3234 (Stop_All_tasks): New function declaration.
3236 2007-09-26 Olivier Hainque <hainque@adacore.com>
3238 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
3239 #include <utime.h> and #define GCC_RESOURCE_H before

3241 Add more protections in __gnat_translate_vms.
3243 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
3244 #include <sys/wait.h>.
3246 2007-09-26 Thomas Quinot <quinot@adacore.com>
3247 Sergey Rybin <rybin@adacore.com>
3249 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
3251 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
3254 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
3256 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
3259 * sem_dist.ads: Minor comment fix
3261 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
3263 2007-09-26 Javier Miranda <miranda@adacore.com>
3264 Eric Botcazou <ebotcazou@adacore.com>
3267 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
3268 indirection added to the HT_Link component of the TSD. This is required
3269 to statically allocate the TSD.
3272 Minor reordering of the declarations in the private part. Required to
3273 add a level of indirection to the contents of the TSD component HT_Link.
3274 This is required to statically allocate the TSD.
3276 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
3277 Is_Statically_Allocated set from constant objects.
3278 Do not make exported constants created by the compiler volatile.
3279 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
3282 * trans.c (Identifier_to_gnu): For constants, unshare initializers
3283 before returning them.
3285 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
3286 public part of the package.
3287 (Make_DT): Move HT_Link component out of the TSD record. For this
3288 purpose Make_DT now declares a separate object that stores the
3289 HT_Link value, and initializes the TSD component with the address
3290 of this new object. The addition of this level of indirection is
3291 required to statically allocate the TSD because the TSD cannot
3292 have variable components.
3293 (Expand_Interface_Conversion): Improve the expanded code.
3294 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
3296 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
3297 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
3298 if we are building static dispatch tables then we must not generate
3299 extra code to register the primitive because the dispatch table will
3300 be built at the end of the library package; otherwise we notify that
3301 we cannot build the static dispatch table.
3303 2007-09-26 Robert Dewar <dewar@adacore.com>
3305 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
3308 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
3309 (Analyze_Record_Representation_Clause): Suppress junk warning for
3310 missing component clause.

3312 tests for controlled type overlay to composites with controlled
3314 (Analyze_Record_Representation_Clause): Add reference for component name
3316 2007-09-26 Javier Miranda <miranda@adacore.com>
3317 Gary Dismukes <dismukes@adacore.com>

3320 for thunks associated with interface types.
3322 * einfo.ads: Improve documentatation of Is_Internal
3323 (Is_Thunk): New attribute applicable to subprograms. True for thunks
3324 associated with interface types.
3325 Extensive comment fixes regarding flags that appear in all entities. The
3326 documentation is now consistent for all such flags (there were a number
3327 of errors in the documentation in this regard).
3329 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
3331 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
3332 of these procedures are passed a function call that already has
3333 build-in-place actuals (testing new flag
3334 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
3335 the case where processing continues.
3336 (Expand_Call): If the call is generated from a thunk body then we
3337 propagate the extra actuals associated with the accessibility
3338 level of the access type actuals.
3340 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
3341 of each extra formal of a protected operation to reference the
3342 corresponding extra formal of the subprogram denoted by the
3343 operation's Protected_Body_Subprogram.
3345 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
3346 N_Function_Call nodes.
3348 2007-09-26 Robert Dewar <dewar@adacore.com>
3350 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
3352 * debug.adb: Add d.s flag.
3354 2007-09-26 Gary Dismukes <dismukes@adacore.com>
3356 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
3357 debug variable so that it won't be initialized when pragma
3358 Initialize_Scalars is in effect.
3360 2007-09-26 Gary Dismukes <dismukes@adacore.com>
3362 * freeze.adb (Freeze_Entity): Remove check for preelaborable
3363 initialization of a full view. This is moved to
3364 Analyze_Package_Specification.
3366 * sem_ch7.adb (Analyze_Package_Specification): Add check for
3367 preelaborable initialization of a full view in entity loop.
3368 (Uninstall_Declarations): If entity is a use-visible compilation unit,
3369 its child units are use-visible only if they are visible child units.
3371 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
3372 whether an expression can be used within a type declaration that
3373 requires preelaborable init.
3374 (Check_Components): Replace inline code that does partial checking for
3375 preelaborable default expressions with call to
3376 Is_Preelaborable_Expression.
3377 (Has_Preelaborable_Initialization): In the case of a generic actual
3378 subtype, (that is, Is_Generic_Actual is True), return the result of
3379 applying Has_Preelaborable_Initialization to the generic actual's base
3382 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
3384 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
3385 call to Jan_1_Day _Of_Week to optimize its performance.
3386 (Is_Leap): Move the routine to the scope of Week_In_Year.
3387 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
3388 weekday on which January 1 falls of Year - 1 and Year + 1. This function
3389 avoids calling Time_Of and Split, thus making it more efficent.
3390 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
3392 * g-calend.ads (Week_In_Year): Change comment to reflect new
3395 2007-09-26 Emmanuel Briot <briot@adacore.com>
3397 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
3398 Command_Line): New types
3399 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
3400 support for defining how switches can be grouped on a command line (as
3401 is the case for -gnatw... for GNAT), and how simple switches can be
3402 used as aliases for more complex switches (-gnatwa is same as
3404 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
3405 (Start, Current_*): New subprograms
3406 Added support for parsing an array of strings in addition to the real
3408 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
3409 be moved from the body to the private part of the spec.
3410 (*): All subprograms now have an extra parameter with default value to
3411 specify which parser should be used. For backward compatibility, it
3412 defaults to parsing the command line of the application. They were also
3413 modified to properly handle cases where each of the argument does not
3414 start at index 1 (which is always true for Ada.Command_Line, but not
3415 when processing any Argument_List).
3416 (Free): New subprogram
3417 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
3418 Argument): New subprograms
3419 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
3420 special characters like ':', '=',... are now handled in a single place,
3421 which makes the code more extensible eventually.
3422 (Getopt, Full_Switch): When the switch was returned as part of the
3423 special character '*', make sure it is prepended by the switch character
3424 ('-' in general), so that the application knows whether "foo" or "-foo"
3425 was specified on the command line.
3427 2007-09-26 Florian Villoing <villoing@adacore.com>
3429 * g-dirope.adb (Remove_Dir): In case we are removing directories
3430 recursively, make sure that if an exception is raised during the
3431 processing, the current working directory is reset to its initial
3432 value before propagating the exception.
3434 2007-09-26 Vincent Celier <celier@adacore.com>
3436 * gnatbind.adb: If there are several ALI files specified and there is
3437 a main program to bind, the first ALI is expected to contain the main
3438 subprogram and the names of the binder generated files will be derived
3439 from the first ALI file name.
3440 (Gnatbind): Fix insertion character in invocation of Error_Msg
3442 2007-09-26 Vincent Celier <celier@adacore.com>
3444 * gnatcmd.adb (Check_Files): Do not include sources that have been
3445 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
3447 2007-09-26 Ed Schonberg <schonberg@adacore.com>
3449 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
3450 information about each of its index types, following the type
3451 reference for its component type.
3453 2007-09-26 Vincent Celier <celier@adacore.com>
3455 * make.adb: (Kill): New procedure (__gnat_kill imported)
3456 (Running_Compile, Outstanding_Compiles): Global variables that
3457 were previously local to procedure Compile_Sources.
3458 (Sigint_Intercepted): Send signal SIGINT to all outstanding
3459 compilation processes.
3461 (Gnatmake): If project files are used, create the mapping of all the
3462 sources, so that the correct paths will be found.
3464 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
3466 2007-09-26 Vincent Celier <celier@adacore.com>
3468 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
3470 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
3471 Replace components Compiler_Min_Options and Binder_Min_Options with
3472 Compiler_Required_Switches and Binder_Required_Switches in record
3474 Remove components Default_Language and Config in Project_Tree_Data,
3477 * prj-attr.adb: New attributes Required_Switches (<language>) in
3478 packages Compiler and Binder.
3480 * prj-nmsc.adb: Major rewrite of the processing of configuration
3481 attributes for gprbuild. No impact on GNAT tools.
3483 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
3484 process configuration attributes: this is done in Prj.Nmsc.Check.

3823 potentially be called.
3824 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
3825 body for 'Output when the type is abstract (only the creation of the
3826 body for 'Input is excluded when the type is abstract).
3827 (Stream_Operation_OK): Add an additional condition in the return
3828 statement, so that False will be returned for TTS_Stream_Input if the
3829 associated tagged type is an abstract extension. Add comments for
3831 (Expand_N_Object_Declaration): For the case of a shared passive
3832 variable, insert init proc call only after the shared variable
3833 procedures have been processed, because the IP call needs to undergo
3834 shared passive variable reference expansion, which requires these
3835 procedures to be available (and elaborated).

3851 to remove other spurious ambiguities on arithmetic operations involving
3852 literals and addresses, on systems where Address is a visible integer
3853 type, when the operator is called in functional notation.
3854 (Try_Primitive_Operation): Within an instance, a call in prefixed form
3855 is legal when the types match, even if the operation is currently

4003 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
4004 library-level package renaming, pass the declaration associated with

4045 * stringt.adb (Store_String_Chars): Optimize by growing the
4046 String_Chars table all at once, rather than appending characters one by
4048 (Write_String_Table_Entry): If the string to be printed is very long,
4049 just print the first few characters, followed by the length. Otherwise,
4050 doing "pn(n)" in the debugger can take an extremely long time.
4052 * sem_prag.adb (Process_Interface_Name): Replace loop doing

4072 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
4073 flag, for effiency. It is called when analyzing arithmetic operators
4074 and also for actuals in calls that are universal_integers. The flag is
4075 set for the predefined type address, and for any type or subtype
4078 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
4079 Universal_Integer, when the formal is a descendent of address and the

4150 renaming declarations.
4152 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.

4160 (Debug_Renaming_Declaration): Replace creation of an enumeration type
4161 and literal with creation of a variable of type
4162 Standard_Debug_Renaming_Type whose name encodes both the renamed object
4163 and the entity of the renaming declaration.

4173 Javier Miranda <miranda@adacore.com>
4175 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
4176 ancestor part given by an aggregate to test for an unchecked conversion,
4177 since this can occur in some cases when the ancestor part is a function
4178 call, and we don't want to fall into the recursive call to this
4179 procedure in that case.
4181 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
4182 stream attributes on limited types to account for user-specified
4183 attributes as well as whether Input (resp. Output) becomes available
4184 due to Read (resp. Write) being available for the type. Change Boolean
4185 variable to the more accurate name
4186 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
4187 double-"not" predicate at beginning of return statement to more
4188 understandable form.
4190 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
4191 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
4192 in a block statement and use that as the first statement of the
4193 expanded return rather than incorrectly using the handled sequence as
4194 the first statement.
4196 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
4197 operation, generate an explicit freeze node for it rather than
4198 generating extra formals, to ensure that gigi has the proper order of
4199 elaboration for anonymous subtypes in the signature of the subprograms.
4200 (Build_In_Place_Formal): Move assertion to beginning of loop.
4201 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
4202 applied to a function call (occurs for some cases of 'Input).

4204 applied to a function call (occurs for some cases of 'Input).
4206 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
4207 2005, generate an extended return statement enclosing the result object
4210 * freeze.adb (Freeze_Record_Type): Extend the current management of
4211 components that are access type with an allocator as default value: add
4212 missing support to the use of qualified expressions of the
4213 allocator (which also cause freezing of the designated type!)
4214 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
4215 dispatching operation, since extra formals may be needed by calls to
4216 build-in-place functions (such as stream 'Input).
4218 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
4219 formals for 'Constrained and accessibility level in the case of a
4220 predefined dispatching operation.
4222 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
4223 point, no need to find the parent node.
4225 2007-08-16 Javier Miranda <miranda@adacore.com>
4227 * exp_attr.adb (Attribute_Priority): Add missing support for entries
4230 2007-08-16 Javier Miranda <miranda@adacore.com>
4232 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
4233 is not really required and can introduce regression with the debugger.
4234 The original problem is fixed with the patch written for checks.adb.
4236 2007-08-16 Thomas Quinot <quinot@adacore.com>
4238 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

4248 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
4249 parameter Including_Non_Switch, defaulted to True. When
4250 Including_Non_Switch is False, options that are not switches and

4273 2007-08-16 Ed Schonberg <schonberg@adacore.com>
4275 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
4276 generic for an enclosing instance is a global reference, even though
4277 its scope is the enclosing instance.

4303 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
4304 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
4305 the statement which is being resolved comes from a predefined library
4306 unit, all non-predefined library interpretations are skipped.
4307 (Resolve_Op_Concat): If string concatenation was folded in the parser,
4308 but the "&" is user defined, give an error, because the folding would
4311 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
4312 the parser has folded a long sequence of concatenations of string
4315 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
4316 and "JMP_BUF" variables as artificial.

4371 needed for access to concurrent record types generated by the expander.
4372 (Generate_Range_Check): When generating a temporary to capture the
4373 value of a conversion that requires a range check, set the type of the

4375 properly placed for back-end use.
4376 (Apply_Float_Conversion_Check): Handle case where the conversion is
4378 (Get_Discriminal): Code reformatting. Climb the scope stack looking

4401 (Expand_N_Type_Conversion): On an access type conversion involving an
4402 access parameter, do not apply an accessibility check when the
4403 operand's original node was an attribute other than 'Access. We now
4404 create access conversions for the expansion of 'Unchecked_Access and
4405 'Unrestricted_Access in certain cases and clearly accessibility should
4406 not be checked for those.
4408 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
4409 includes a type conversion of a packed component that has been expanded,
4410 recover the original expression for the object, and use this expression
4411 in the post-call assignment statement, so that the assignment is made
4412 to the object and not to a back-end temporary.
4413 (Freeze_Subprogram): In case of primitives of tagged types not defined
4414 at the library level force generation of code to register the primitive
4415 in the dispatch table. In addition some code reorganization has been
4416 done to leave the implementation clear.
4417 (Expand_Call): When expanding an inherited implicit conversion,
4418 preserve the type of the inherited function after the intrinsic
4419 operation has been expanded.
4421 * exp_ch2.ads, exp_ch2.adb
4422 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
4423 of an entry formal appearing in an assignment statement does not assign
4425 (Expand_Current_Value): Instead of calling a routine to determine
4426 whether the prefix of an attribute reference should be optimized or
4427 not, prevent the optimization of such prefixes all together.
4429 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
4430 component whose prefix is known to be of an access type is an implicit
4431 dereference and does not assign to the prefix.
4433 2007-08-14 Ed Schonberg <schonberg@adacore.com>
4434 Robert Dewar <dewar@adacore.com>
4436 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
4437 itype is visited, make an entry into table to link associated node and
4439 Add comments and correct harmless error in Build_NCT_Hash_Tables
4440 (Array_Aggr_Subtype): Associate each itype created for an index type to
4441 the corresponding range construct, and not to the aggregate itself. to
4442 maintain a one-to-one correspondence between itype and its associated
4443 node, to prevent errors when complex expression is copied.
4444 Fix mishandling of multiple levels of parens
4446 * sem_aggr.adb: Create a limited view of an incomplete type, to make
4447 treatment of limited views uniform for all visible declarations in a
4448 limited_withed package.
4449 (New_Copy_Tree): If hash table is being used and itype is visited,
4450 make an entry into table to link associated node and new itype.
4451 (Resolve_Record_Aggregate): Do not add an others box association for a
4452 discriminated record component that has only discriminants, when there
4453 is a box association for the component itself.
4455 * par-ch4.adb: Fix mishandling of multiple levels of parens

4490 Javier Miranda <miranda@adacore.com>
4491 Gary Dismukes <dismukes@adacore.com>
4493 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
4494 to make treatment of limited views uniform for all visible declarations
4495 in a limited_withed package.
4496 Improve warnings for in out parameters
4497 (Set_Related_Interaface/Related_Interface): Allow the use of this
4498 attribute with constants.
4499 (Write_Field26_Name): Handle attribute Related_Interface in constants.
4500 Warn on duplicate pragma Preelaborable_Initialialization
4502 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
4503 generation of a freezing node to ensure proper management of null
4504 excluding access types in the backend.
4505 (Create_Extra_Formals): Test base type of the formal when checking for
4506 the need to add an extra accessibility-level formal. Pass the entity E
4507 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
4508 originally being done in a couple of cases), to ensure that the
4509 Extra_Formals list gets set on the entity E when the first entity is
4511 (Conforming_Types): Add missing calls to Base_Type to the code that
4512 handles anonymous access types. This is required to handle the
4513 general case because Process_Formals builds internal subtype entities
4514 to handle null-excluding access types.
4515 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
4516 functions that need it, even when not marked Requires_Overriding.
4517 Improve warnings for in out parameters
4518 (Analyze_Function_Return): Warn for disallowed null return
4519 Warn on return from procedure with unset out parameter
4520 Ensure consistent use of # in error messages
4521 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
4522 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
4523 the implicit conversion of the expression done for anonymous access
4524 types. This is required to generate the code of the null excluding
4525 check (if required).
4527 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
4528 A formal parameter is never publicly referenceable outside of its body.
4529 (Check_References): For an unreferenced formal parameter in an accept
4530 statement, use the same warning circuitry as for subprogram formal
4532 (Warn_On_Unreferenced_Entity): New subprogram, taken from
4533 Output_Unreferenced_Messages, containing the part of that routine that
4534 is now reused for entry formals as described above.
4535 (Goto_Spec_Entity): New function
4536 (Check_References): Do not give IN OUT warning for dispatching operation
4537 Improve warnings for in out parameters
4538 (Test_Ref): Check that the entity is not undefinite before calling
4539 Scope_Within, in order to avoid infinite loops.
4540 Warn on return from procedure with unset out parameter
4541 Improved warnings for unused variables

4544 Javier Miranda <miranda@adacore.com>
4545 Gary Dismukes <dismukes@adacore.com>
4547 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
4548 (Expand_N_Attribute_Reference): Further unify the handling of the
4549 three forms of access attributes, using common code now for all three
4550 cases. Add a test for the case of applying an access attribute to
4551 an explicit dereference when the context is an access-to-interface
4552 type. In that case we need to apply the conversion to the prefix
4553 of the explicit dereference rather than the prefix of the attribute.
4554 (Attribute_Version, UET_Address): Set entity as internal to ensure
4555 proper dg output of implicit importation.
4556 (Expand_Access_To_Type): Removed.
4557 (Expand_N_Attribute_Reference): Merge the code from the three cases
4558 of access attributes, since the processing is largely identical for
4559 these cases. The substantive fix here is to process the case of a
4560 type name prefix (current instance case) before handling the case
4561 of interface prefixes.
4563 2007-08-14 Thomas Quinot <quinot@adacore.com>
4564 Ed Schonberg <schonberg@adacore.com>
4565 Javier Miranda <miranda@adacore.com>
4566 Robert Dewar <dewar@adacore.com>
4568 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
4569 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
4570 type that is an anonymous access to controlled object, establish
4571 an associated finalization chain to avoid corrupting the global
4572 finalization list when a dynamically allocated object designated
4573 by such a component is deallocated.
4574 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
4575 functions that need it, even when not marked Requires_Overriding.
4576 (Initialize_Tag): Replace call to has_discriminants by call to
4577 Is_Variable_Size_Record in the circuitry that handles the
4578 initialization of secondary tags.
4579 (Is_Variable_Size_Record): New implementation.
4580 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
4581 Suppress_Initialization pragma for a derived type.
4582 (Is_Variable_Size_Record): New subprogram.
4583 (Build_Offset_To_Top_Functions): New implementation that simplifies the
4584 initial version of this routine and also fixes problems causing
4585 incomplete initialization of the table of interfaces.
4586 (Build_Init_Procedure): Improve the generation of code to initialize the
4587 the tag components of secondary dispatch tables.
4588 (Init_Secondary_Tags): New implementation that simplifies the previous
4589 version of this routine.
4590 (Make_DT): Add parameter to indicate when type has been frozen by an
4591 object declaration, for diagnostic purposes.
4592 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
4593 diagnose attemps to freeze a subprogram when some untagged type of its
4594 profile is a private type whose full view has not been analyzed yet.
4595 (Freeze_Array_Type): Generate init proc for packed array if either
4596 Initialize or Normalize_Scalars is set.
4597 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
4598 constructing the new profile, copy the null_exclusion indicator for each
4599 parameter, to ensure full conformance of the new body with the spec.
4601 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
4602 Create wrappers for constructor functions that need it, even when not
4603 marked Requires_Overriding.
4604 (Covers): Handle properly designated types of anonymous access types,
4605 whose non-limited views are themselves incomplete types.
4606 (Add_Entry): Use an entity to store the abstract operation which hides
4608 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

4614 they are labeled as potentially hidden by an abstract operator.
4615 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
4616 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
4617 (Write_Overloads): Output the abstract operator if present.
4618 (Add_Entry): Before inserting a new entry into the interpretation table
4619 for a node, determine whether the entry will be disabled by an abstract
4621 (Binary_Op_Interp_May_Be_Hidden): New routine.
4622 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
4624 (Function_Interp_May_Be_Hidden): New routine.
4625 (Has_Compatible_Type): Do not consider interpretations hidden by
4626 abstract operators when trying to determine whether two types are
4628 (Has_Hidden_Interp): New routine.

4633 Javier Miranda <miranda@adacore.com>
4635 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
4636 types declared in the declarative part of a nested package body or in
4637 the proper body of a stub.

4642 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
4643 output of implicit importation and exportation.
4644 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
4645 first formal of the thunk is always associated with the controlling
4646 type. In addition perform the following code cleanup: remove formal
4647 Thunk_Alias which is no longer required, cleanup evaluation of the
4648 the controlling type, and update the documentation.
4649 Replace occurrence of Default_Prim_Op_Count by
4650 Max_Predef_Prims. Addition of compile-time check to verify
4651 that the value of Max_Predef_Prims is correct.
4652 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
4653 (Make_DT): Add parameter to indicate when type has been frozen by an
4654 object declaration, for diagnostic purposes.
4655 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
4656 construction of statically allocated dispatch tables.
4657 (Make_DT): In case of library-level tagged types export the declaration
4658 of the primary tag. Remove generation of tags (now done by Make_Tags).
4659 Additional modifications to handle non-static generation of dispatch
4660 tables. Take care of building tables for asynchronous interface types
4661 (Make_Tags): New subprogram that generates the entities associated with
4662 the primary and secondary tags of Typ and fills the contents of Access_
4663 Disp_Table. In case of library-level tagged types imports the forward
4664 declaration of the primary tag that will be declared later by Make_DT.
4665 (Expand_Interface_Conversion): In case of access types to interfaces
4666 replace an itype declaration by an explicit type declaration to avoid
4667 problems associated with the scope of such itype in transient blocks.
4669 2007-08-14 Robert Dewar <dewar@adacore.com>
4670 Ed Schonberg <schonberg@adacore.com>
4671 Javier Miranda <miranda@adacore.com>
4673 * exp_util.ads, exp_util.adb:
4674 This patch replaces a number of occurrences of explicit tests for N_Null
4675 with calls to Known_Null. This improves tracking of null values, since
4676 Known_Null also catches null constants, and variables currently known to
4677 be null, so we get better tracking.
4678 (Ensure_Defined): create an itype reference only in the scope of the
4680 (Side_Effect_Free): A selected component of an access type that
4681 denotes a component with a rep clause must be treated as not
4682 side-effect free, because if it is part of a linked structure its
4683 value may be affected by a renaming.
4684 (Expand_Subtype_From_Expr): For limited objects initialized with build
4685 in place function calls, do nothing; otherwise we prematurely introduce
4686 an N_Reference node in the expression initializing the object, which
4687 breaks the circuitry that detects and adds the additional arguments to
4688 the called function. Bug found working in the new patch for statically
4689 allocated dispatch tables.
4690 (Is_Library_Level_Tagged_Type): New subprogram.
4691 (Remove_Side_Effects): If the expression of an elementary type is an
4692 operator treat as a function call.
4693 (Make_Literal_Range): If the index type of the array is not integer, use
4694 attributes properly to compute the constraint on the resulting aggregate
4697 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
4698 class-wide type whose base type is an incomplete private type, leave
4699 class-wide type unfrozen so that freeze nodes can be generated
4700 properly at a later point.
4701 (Freeze_Entity, array case): Handle case of pragma Pack and component
4702 size attributre clause for same array.

4759 attribute Body in package Naming. Do not replace a source/unit in the
4760 same project when the order of the source dirs are known. Detect
4761 duplicate sources/units in the same project when the order of the
4762 source dirs are not known.
4763 (Check_Ada_Name): Allow all identifiers that are not reserved words
4765 Major update of the Project Manager and of the project aware tools,
4766 including gprmake, so that the same sources in the GNAT repository
4767 can be used by gprbuild.

4769 directory of non extending project to nil.
4770 Change type of path name variables to be Path_Name_Type
4771 (Locate_Directory): Make sure that on Windows '/' is converted to '\',
4772 otherwise creating missing directories will fail.

5375 parameter to determine whether operation applies to the prefix.
5376 (Complete_Object_Operation): If actual has an access type and
5377 controlling formal is not an in_parameter, reject the actual if it is
5378 an access_to_constant type.
5379 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
5380 type, the candidate operations are found in the scope of declaration of
5381 the type, because the type has no primitive subprograms.
5382 (Analyze_Selected_Component): If prefix is class-wide, and root type is
5383 a private extension, only examine visible components before trying to
5384 analyze as a prefixed call.
5385 Change Entity_List to Type_To_Use, for better readability.

5399 purpose of enforcing E.2.2(8) only if it is not available at any place.
5400 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
5401 when checking the legality of an extension aggregate in a preelaborable
5402 package. Treat the literal null as a valid default expression in a
5403 component declaration for a type with preelaborable initialization.
5404 A limited interface is a legal progenitor for the designated type of a
5405 remote access to class-wide type.

5435 when the type of the interpretation matches that of the context.
5436 (Resolve): When looping through all possible interpretations of a node,
5437 do not consider those that are hidden by abstract operators.
5438 (Resolve_Actuals): When verifying that an access to class-wide object
5439 is an actual for a controlling formal, ignore anonymous access to
5440 subprograms whose return type is an access to class_wide type.
5441 (Resolve_Slice): If the prefix of the slice is a selected component
5442 whose type depends on discriminants, build its actual subtype before
5443 applying range checks on the bounds of the slice.

5445 to prevent anomalies between private and public views.

6621 applicable to types that have the With_Type flag set. Returns the
6622 non-limited view of the type, if available, otherwise the type itself.

6647 tagged type, do not consider subprograms labeled as hidden unless they
6648 belong to a private generic type with a tagged parent.
6649 (Try_Object_Operation): Extensive rewriting, to handle properly various
6650 overloading cases, when several ancestors may have class-wide operations
6651 that are possible candidates, and when the overloaded functions return
6652 array types and have defaulted parameters so that the call may be
6653 interpreted as an indexing.
6654 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
6655 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
6656 successive actuals before analyzing the call itself.
6657 (Try_Primitive_Operation): A primitive operation is compatible with the
6658 prefix if the prefix has a synchronized type and the type of the formal
6659 is its corresponding record, as can be the case when the primitive
6660 operation is declared outside of the body of the type.
6661 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
6662 perform homonym traversal, looking for class-wide operation matches

6665 (Mark_Allocator): An allocator with a discriminant association parent is
6667 (Try_One_Prefix_Interpretation): If the type of the object is
6668 incomplete, as can be happen when it is a limited view obtained through

6672 aliased when the corresponding controlling formal is an access
6674 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
6675 ambiguous calls in prefixed notation, where two primitives differ only
6676 in that the controlling argument of one is an access parameter.

6679 whether a function that returns an unconstrained type can be inlined.
6680 (Process_Formals): Diagnose properly the illegal use of an incomplete
6681 type in the profile of an access_to_subprogram declaration.
6682 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
6683 operations are attached to the corresponding record.
6684 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.

6686 interface change the type of all controlling formals to that of the
6687 corresponding record type.

6689 to determine the tagged type to which a primitive belongs.

6691 (which is shared between the loop in Check_Conventions and the one in
6692 Check_Convention) in a new local function Skip_Check.

6694 confusion with Check_Conventions' own Prim_Op local variable.

6696 controlling result when determining whether to add a BIP_Alloc_Form
6697 formal and a BIP_Final_List formal to the function.
6698 (Check_Conformance); For parameters that are anonymous access types,
6699 subtype conformance requires that the not null and the constant
6700 indicators must match
6701 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
6702 to retrieve the appropriate type when processing a concurrent type
6703 declared within a generic. Minor comment reformatting. Change invocation
6704 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
6706 (Analyze_Subprogram_Body): If the return type of a function is an
6707 anonymous access to the limited view of a class-wide type, and the
6708 non-limited view of the type is available, update the type of the
6709 function so that code can be generated.
6710 (Process_Formals): In case of access-subtype itype whose designated
6711 type is also an itype (situation that happens now with access to
6712 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
6713 attribute to avoid backend problems.
6714 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
6715 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
6716 anonymous types' designated types are same before testing
6717 Subtypes_Statically_Match.
6718 (Create_Extra_Formals): Test for a named access parameter that is a
6719 controlling formal as an additional condition for adding an
6720 accessibility level formal. This can occur in the subp type created for
6721 dispatching calls in Expand_Dispatching_Call, and allows calling
6722 Create_Extra_Formals from that procedure rather than special-casing the
6723 extra formals there.
6724 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
6725 when the function has a controlling result.
6726 (Check_Returns): Add much more knowledge of the optimization of local
6727 raise statements to gotos, to retain proper warnings in this case.
6728 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
6729 nodes when looking for last statement.
6731 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
6732 class-wide types visible through limited with clauses.
6733 (Add_One_Interp): If the operands are anonymous access types, the
6734 predefined operator on universal_access is immediately visibles
6735 (Find_Unique_Type): Handle anonymous access to subprogram types just as
6736 other anonymous access types.
6737 (Disambiguate): Take into account CIL convention.
6738 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
6740 2007-06-06 Robert Dewar <dewar@adacore.com>
6742 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
6743 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
6744 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
6745 Fix lower bound of tables.
6748 * nlists.adb: Ditto.
6749 (Prev_Node, Next_Node): Change index type to Int so that it properly
6750 covers the range First_Node_Id - 1 up.
6752 2007-06-06 Javier Miranda <miranda@adacore.com>
6753 Ed Schonberg <schonberg@adacore.com>
6754 Bob Duff <duff@adacore.com>
6755 Hristian Kirtchev <kirtchev@adacore.com>
6757 * exp_aggr.ads, exp_aggr.adb:
6758 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
6759 in extension aggregates.
6760 (Flatten): Other conditions being met, an aggregate is static if the
6761 low bound given by component associations is different from the low
6762 bound of the base index type.
6763 (Packed_Array_Aggregate_Handled): If the component type is itself a
6764 packed array or record, the front-end must expand into assignments.
6765 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
6766 Init_Pr, instead of Ancestor_Is_Expression.
6767 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
6768 coextension chain root, either generate a list controller or use the
6769 already existing one.
6770 (Static_Array_Aggregate): New procedure to construct a positional
6771 aggregate that can be handled by the backend, when all bounds and
6772 components are compile-time known constants.
6773 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
6774 types covering interface types into assignments.
6775 (Replace_Type): move to Build_Record_Aggr_Code.
6776 (Expand_Record_Aggr_Code): if the target of the aggregate is an
6777 interface type, convert to the definite type of the aggregate itself,
6778 so that needed components are visible.
6779 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
6780 components and the context is an extended return statement do not
6781 create a transient block for it, to prevent premature finalization
6782 before the return is executed.
6783 (Gen_Assign): Do not generate a call to deep adjust routine if the
6784 component type is itself an array of controlled (sub)-components
6785 initialized with an inner aggregate.
6786 (Component_Check): New name for Static_Check. This name is now more
6787 appropriate, and documentation is added which was missing.
6788 (Component_Check): Add test for bit aligned component value
6789 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
6790 Tagged_Comps, name is more appropriate given added function below.
6791 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

6794 Javier Miranda <miranda@adacore.com>
6795 Robert Dewar <dewar@adacore.com>
6797 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
6798 Terminated: Add unchecked type conversion from System.Address to
6799 System.Tasking.Task_Id when calling the predefined primitive
6801 Disable new Ada 05 accessibility check for JVM.NET targets, which
6802 cannot be implemented in a practical way.
6803 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
6804 the sources always references the tag of the actual object. Therefore,
6805 if 'Tag is applied in the sources to class-wide interface objects we
6806 generate code that displaces "this" to reference the base of the object.
6807 (Expand_N_Attribute_Reference, case Size): Return specified size if
6809 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
6810 has code that displaces the pointer of the object to manage interface
6811 types. However this code must not be executed when the prefix is a
6812 subprogram. This bug caused the wrong expansion of the internally
6813 generated assignment that fills the dispatch table when the primitive
6814 is a function returning a class-wide interface type.
6815 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
6816 Set_Attribute_Name for Name_Unaligned_Valid.
6818 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6819 Gary Dismukes <dismukes@adacore.com>
6821 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
6822 If the initialization is the equivalent aggregate of the initialization
6823 procedure of the type, do not remove it.
6824 (Expand_N_Attribute_Definition_Clause): Exclude access variables
6825 initialized to null from having their expression reset to empty and
6826 note this exception in the comment.
6828 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
6829 Robert Dewar <dewar@adacore.com>
6830 Ed Schonberg <schonberg@adacore.com>
6831 Gary Dismukes <dismukes@adacore.com>
6833 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
6834 Add "with" and "use" clauses for Sem_Attr.
6835 (Expand_Current_Value): Do not replace occurences of attribute
6836 references where the prefix must be a simple name.
6838 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
6839 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
6840 Attribute_Requires_Simple_Name_Prefix.
6841 (Name_Modifies_Prefix): Body of new function.
6842 (Requires_Simple_Name_Prefix): Body of new function.
6843 (Resolve_Attribute, case Access): Improve error message for case of
6844 mismatched conventions.
6845 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
6847 (Analyze_Attribute, case 'Access): If the type of the prefix is a
6848 constrained subtype for a nominal unconstrained type, use its base type
6849 to check for conformance with the context.
6850 (Resolve_Attribute): Remove test of the access type being associated
6851 with a return statement from condition for performing accessibility
6852 checks on access attributes, since this case is now captured by
6853 Is_Local_Anonymous_Access.
6854 (Analyze_Access_Attribute): Set Address_Taken on entity
6855 (Analyze_Attribute, case Address): Set Address_Taken on entity
6856 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
6857 validating an access attribute whose prefix is a current instance.
6858 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
6859 applied to dispatching operations, if freezing is required then we set
6860 the attribute Has_Delayed_Freeze in the prefix's entity.
6861 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
6862 current scope if access of local subprogram taken
6863 (Analyze_Access_Attribute): Check legality of self-reference even if the
6864 expression comes from source, as when a single component association in
6865 an aggregate has a box association.
6866 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
6867 the prefix if it is a protected operation and the attribute is
6868 Unrestricted_Access.
6869 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
6870 reference to the base type of the context, to force a constraint check
6871 when the context is an access subtype with an explicit constraint.
6872 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
6873 node is rewritten as an interface conversion. leave unanalyzed after
6874 resolution, to ensure that type checking against the context will take
6877 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6878 Javier Miranda <miranda@adacore.com>
6879 Robert Dewar <dewar@adacore.com>
6881 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
6882 wrapper when the full view of the controlling type of an inherited
6883 function that dispatches on result implements interfaces.
6884 (Expand_N_Object_Declaration): In cases where the type of the
6885 declaration is anonymous access, create finalization list for it.
6886 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
6887 if the object has no explicit initialization, to match description of
6888 functionality of pragam Persistent_BSS.
6889 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
6890 new function to build static aggregates, to replace initialization call
6891 when static initialization is desired.
6892 (Freeze_Type): Generate a list controller for an access type whenever
6893 its designated type has controlled anonymous access discriminants.
6894 (Build_Equivalent_Aggregate): New procedure to compute a static
6895 aggregate to be used as default initialization for composite types,
6896 instead of a generating a call to the initialization procedure for the
6898 (Build_Initialization_Call): When available, replace a call to the
6899 initialization procedure with a copy of the equivalent static aggregate
6901 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
6902 declarations for objects of a class-wide interface type, rather than
6903 just identifiers, to prevent visibility problems.
6904 (Expand_N_Object_Declaration): When expanding the declaration for an
6905 object of a class-wide interface type, preserve the homonym chain of
6906 the original entity before exchanging it with that of the generated
6907 renaming declaration.
6908 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
6909 active, because there is no way to handle the exception.
6910 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
6911 to do a minimum decoration of the Access_Disp_Table list.
6912 (Expand_Record_Controller): Avoid the addition of the controller between
6913 the component containing the tag of a secondary dispatch table and its
6914 adjacent component that stores the offset to the base of the object.
6915 This latter component is only generated when the parent type has
6916 discriminants ---documented in Add_Interface_Tag_Components).
6917 (Apply_Array_Size_Check): Removed, no longer needed.
6918 (Expand_N_Full_Type_Declaration): If the type has anonymous access
6919 components, create a Master_Entity for it only if it contains tasks.
6920 (Build_Init_Procedure): Suppress the tag assignment compiling under
6922 (Freeze_Record_Type): Remove code associated with creation of dispatch
6924 (Init_Secondary_Tags): Update type of actuals when generating calls to
6925 Ada.Tags.Set_Offset_To_Top
6926 (Stream_Operation_OK): Disable use of streams compiling under no
6928 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
6929 if Has_Init_Expression set.
6930 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
6931 Register_Primitive, which provides the same functionality.
6932 (Requires_Init_Proc): Return false in case of interface types.
6933 (Add_Secondary_Tables): Use the new attribute Related_Interface to
6935 (Predefined_Primitive_Freeze): Do not assume that an internal entity
6936 is always associated with a predefined primitive because the internal
6937 entities associated with interface types are not predefined primitives.
6938 Therefore, the call to Is_Internal is replaced by a call to the
6939 function Is_Predefined_Dispatching_Operation.
6940 (Make_Eq_If): When generating the list of comparisons for the
6941 components of a given variant, omit the controller component that is
6942 present if the variant has controlled components.
6944 2007-06-06 Javier Miranda <miranda@adacore.com>
6945 Hristian Kirtchev <kirtchev@adacore.com>
6946 Bob Duff <duff@adacore.com>
6948 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
6949 handle the creation of finalization lists and calls for nested
6950 coextensions when the root of the chains is part of a return statement.
6951 (Inside_A_Return_Statement): New function inside Complete_Coextension_
6953 (Expand_Record_Equality): Skip components that are interface types.
6954 (Displace_Allocator_Pointer): Add missing support for interface subtypes
6955 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
6956 with Rewrite_Coextension. Change the condition for detecting coextension
6958 (Is_Local_Access_Discriminant): Removed.
6959 (Rewrite_Coextension): New routine which rewrites a static coextension
6960 as a temporary and uses its unrestricted access in the construction of
6962 (Complete_Coextension_Finalization): New routine. Generate finalization
6963 attachment calls to all delayed coextensions.
6964 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
6965 the allocator is not a coextension itself and has delayed coextensions.
6966 If the current allocator is controlled, but also a coextension, delay
6967 the generation of the finalization attachment call.
6968 Rename local variable "Node" to "Nod" in order to avoid confusion with
6970 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
6971 limited types that are not inherently limited. Such an allocator is
6972 illegal, but is generated by the expander for a return statement, to
6973 copy the result onto the secondary stack. This is the only case where a
6974 limited object can be copied. Generate code to displace the pointer
6975 to the object if the qualified expression is a class-wide interface
6976 object. Such displacement was missing and hence the copy of the object
6978 (Apply_Accessibility_Check): Handle allocated objects initialized in
6980 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
6981 and Expand_Allocator_Expression. Allocating class-wide interface objects
6982 this routine displaces the pointer to the allocated object to reference
6983 the component referencing the corresponding secondary dispatch table.
6984 Expand_Allocator_Expression): Add missing support to allocate class-wide
6985 interface objects initialized with a qualified expression.
6986 (Get_Allocator_Final_List): Test for an anonymous access type that is a
6987 function result type, and use the finalization list associated with the
6988 function scope in that case (such an anonymous type should not be
6989 treated like an access parameter's type).
6991 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6992 Gary Dismukes <dismukes@adacore.com>
6993 Javier Miranda <miranda@adacore.com>
6995 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
6996 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
6997 required exception handler.
6998 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
6999 properly the case of a function whose return type is a limited
7000 class-wide interface type. Modify the code of the accessibility
7001 check to handle class-wide interface objects. In this case we need to
7002 displace "this" to reference the primary dispatch table to get access
7003 to the TSD of the object (to evaluate its accessibility level).
7004 (Expand_N_Extended_Return_Statement): Test for a tagged result type
7005 rather than a controlling result as one of the conditions for
7006 generating tests of the implicit BIP_Alloc_Form formal. The
7007 initialization assignment is also handled according to whether the
7008 result is tagged instead of controlling.
7009 In the case where the init assignment is inserted in the "then" part of
7010 the allocation conditional, rewrite the target to be a dereference of
7011 the implicit BIP_Object_Access formal.
7012 If the returned value is unconstrained and created on the secondary
7013 stack, mark the enclosing block and function so that the secondary
7014 stack is not reclaimed on return.
7015 Treat returns from functions with controlling results similarly to
7016 returns from functions with unconstrained result subtypes.
7017 If the object returned is unconstrained, and an allocator must be
7018 created for it, analyze the allocator once the block for the extended
7019 return is installed, to ensure that finalizable components
7020 of the expression use the proper finalization list. Guard the call to
7021 Move_Final_List with a check that there is something to finalize.
7022 (Make_Tag_Ctrl_Assignment): Use "old" handling
7023 of controlled type assignment for virtual machines, since new code uses
7024 unsupported features (such as direct access to bytes in memory).
7026 2007-06-06 Gary Dismukes <dismukes@adacore.com>
7027 Ed Schonberg <schonberg@adacore.com>
7029 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
7030 accessibility actual, check for the case of an aliased object that has
7031 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
7032 we fall into processing for the attribute rather than the name of the
7034 (Expand_Inline_Call): If an actual is a literal, and the corresponding
7035 formal has its address taken in the body, create a temporary to capture
7036 value. If the return type is a limited interface, do not treat the
7037 return value as Controlled.
7038 (Is_In_Place_Function): If the return type is a limited interface,
7039 treat as returning in place. The actual returned object may not always
7040 be limited, but the caller has to assume that it is returned in place.
7041 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
7042 context of an allocator, use the correct finalization chain (that is,
7043 the chain belonging to the access type, rather than the chain belonging
7044 to the current scope).
7045 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
7046 result type rather than a controlling result as a precondition for
7047 adding an allocation form actual to a build-in-place call.
7048 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
7049 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
7050 primitive in the dispatch tables. This work is now done by Make_DT when
7052 (Register_Predefined_DT_Entry): Removed.
7053 (Add_Return): If end label is not present, use sloc of last statement
7054 for generated return statement in procedure, for better gdb behavior
7056 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
7057 object address nodes to ensure proper processing by routines like
7059 (Expand_Call): Fix generation of validity check for parameter
7060 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
7061 the allocation form parameter if the result subtype is constrained,
7062 except when the function has a controlling result.
7063 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
7064 rather than Is_Controlled and Has_Controlled_Component, since we want to
7065 include class-wide result types in this treatment. Also test for a
7066 controlling result, since that also requires passing a finalization
7068 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
7069 even when the result subtype is constrained, to handle calls involving
7070 controlling results.
7071 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
7072 is now called even when the result subtype is constrained, to handle
7073 calls involving controlling results.
7074 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
7075 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
7076 now performs the test).
7077 (Make_Build_In_Place_Call_In_Object_Declaration):
7078 Add_Alloc_Form_Actual_* is now called even when the result subtype is
7079 constrained, to handle calls involving controlling results.
7080 (Add_Return): Accomodate rewritten pattern from local raise to goto
7081 transformation, so that we still recognize an transfer statement
7082 and do the right thing here in that case.
7083 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
7084 and end of subprogram code.
7085 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
7086 support for primitives that are functions (without formals) with a
7088 (Inherited_From_Formal): If the actual subtype has not generic parent
7089 type, it is not an actual for a formal derived type, and there is no
7090 operation to inherit from the formal.
7092 2007-06-06 Ed Schonberg <schonberg@adacore.com>
7093 Thomas Quinot <quinot@adacore.com>
7095 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
7096 inserted cleanup code appropriately for GDB use.
7097 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
7098 exception handler for Deep_Adjust or Deep_Finalize.
7099 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
7100 Raise_From_Controlled_Operation is available, use a call to that
7101 subprogram instead of a plain "raise Program_Error" node to raise
7102 Program_Error if an exception is propagated from an Adjust or Finalize
7104 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
7105 appears in the optional statement list of a triggering alternative, the
7106 scope actions can be inserted directly there, and not in the list that
7107 includes the asynchronous select itself.
7109 2007-06-06 Ed Schonberg <schonberg@adacore.com>
7110 Robert Dewar <dewar@adacore.com>
7111 Hristian Kirtchev <kirtchev@adacore.com>
7113 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
7114 generated exception handler appropriately when debugging generated code.
7115 Deal properly with No_Exception_Propagation restriction mode.
7116 (Expand_N_Abort_Statement): Add an unchecked type conversion from
7117 System.Address to System.Tasking.Task_Id when processing the result of
7118 the predefined primitive _disp_get_task_id.
7119 (Expand_N_Asynchronous_Select): Clarify comment.
7120 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
7121 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
7122 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
7123 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
7124 privals and for generated call to Complete_Entry_Body, for better gdb
7126 (Copy_Result_Type): Utility to construct a parameter and result profile
7127 for protected functions whose return type is an anonymous access to
7129 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
7131 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
7132 point when the local-raise-to-goto transformation has taken place.
7134 2007-06-06 Javier Miranda <miranda@adacore.com>
7135 Nicolas Setton <setton@adacore.com>
7137 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
7138 functionality when the backend is generating code.
7139 Otherwise any serious error
7140 reported by the backend calling the frontend routine Error_Msg
7141 changes the Compilation_Mode to Check_Semantics, disables the
7142 functionality of this routine and causes the generation of
7143 spureous additional errors.
7145 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
7146 debugging information now generated by the compiler for fat-pointer
7148 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
7150 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
7152 2007-06-06 Thomas Quinot <quinot@adacore.com>
7154 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
7155 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
7156 PolyORB_Support.Build_Subprogram_Receiving_Stubs):

7283 subtype from the function call, as is done for private types.
7284 (Side_Effect_Free): An expression that is the renaming of an object or

9150 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
9151 for all access attributes, because overload resolution should work the
9152 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
9153 causes the error message for the ambiguous "X'Access = Y'Access" and
9154 "X'Unrestricted_Access = Y'Access" and so forth to match.
9155 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,

9253 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
9254 when -gnatg is not specified.

9306 parameter of the containing subprogram.
9307 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
9308 under No_Dispatching_Calls restriction. During the semantic analysis
9309 we already notified such violation.

9328 Modify the declaration of the object containing the TSD
9329 because we now expand code that has a higher level of abstraction.
9330 The TSD has a discriminant containing the Inheritance Depth Level,
9331 value that is used in the membership test but also to fix the size
9332 of the table of ancestors.
9333 (Expand_Interface_Conversion): Insert function body at the closest place
9334 to the conversion expression, to prevent access-before-elaboration

9391 support concurrent types implementing interfaces.
9392 (Find_Implemented_Interface): Removed. All the calls to this subprogram

9396 CW_Or_Controlled_Type whenever the issue is related to
9397 using or not the secondary stack.

9492 * Retrieve the extra formals parameters at the
9493 end of the parameter stream.
9494 * Use Move_Any_Value to write back out parameters

9511 (Build_To_Any_Function, Build_From_Any_Function,
9512 Built_TypeCode_Function): When Typ is implicit, call the correct
9513 function with the first not implicit parent type.
9514 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
9515 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
9516 typecode from the Etype. Therefore we retrieve the correct typecode
9517 with a call to Get_Any_Type.
9518 (Copy_Specification): Do controlling formal type substitution based on
9519 Is_Controlling_Formal flag, instead of caller-provided object type.
9520 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
9521 a RACW primitive operation, we might get a subprogram declaration for an
9522 ancestor of the RACW designated type (not for the designated type
9523 itself), in the case where this operation is inherited. In this case we
9524 have no easy means of determining the original tagged type for which
9525 the primitive was declared, so instead we now rely on
9526 Copy_Specification to use the Is_Controlling_Formal flag to determine
9527 which formals require type substitution.

9535 handler unsuitable as a target for a local raise statement.
9536 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
9537 run-time subprogram CW_Membership by call to Build_CW_Membership.
9538 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
9539 by a function call, a temporary must be created before expanding the
9540 Constructor_Call itself, to prevent out-of-order elaboration in the
9541 back-end when stack checking is enabled..

9989 unit, in which case the instance must be analyzed with the latest Ada
9990 mode. This setting must take place after analysis of the actuals,
9991 because the actuals must be analyzed and frozen in the Ada mode extant

10004 Bob Duff <duff@adacore.com>
10005 Gary Dismukes <dismukes@adacore.com>
10007 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
10008 prefix type is a discriminated subtype of the type of the formal.
10009 (Analyze_Allocator): Collect all coextensions regardless of the context.
10010 Whether they can be allocated statically is determined in exp_ch4.
10011 (Analyze_Selected_Component): If the prefix is a limited view and the
10012 non-limited view is available, use the non-limited one.
10013 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
10014 therefore illegal), suggest a qualified expression rather than a type
10015 conversion, because a type conversion would be illegal in this context.
10016 (Anayze_Allocator): Trace recursively all nested allocators so that all
10017 coextensions are on the corresponding list for the root. Do no mark
10018 coextensions if the root allocator is within a declaration for a stack-
10019 allocated object, because the access discriminants will be allocated on
10021 (Analyze_Call): Remove restriction on calls to limited functions for the
10022 cases of generic actuals for formal objects, defaults for formal objects
10023 and defaults for record components.
10024 (Analyze_Allocator): Before analysis, chain coextensions on the proper
10025 element list. Their expansion is delayed until the enclosing allocator
10026 is processed and its finalization list constructed.
10027 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
10028 for an operation with the given name among the primitive operations of
10029 the corresponding record type.
10030 (Analyze_Selected_Component): If the prefix is a task type that
10031 implements an interface, and there is no entry with the given name,
10032 check whether there is another primitive operation (e.g. a function)
10034 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
10035 properly the indexing of a function call written in prefix form, where
10036 the function returns an array type, and all parameters of the function
10037 except the first have defaults.
10038 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
10039 the original operands, rather than relocating them, for efficiency and
10040 to work properly when an operand is overloaded.
10041 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
10042 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
10043 (Analyze_Selected_Component): If the prefix is a private extension, only
10044 scan the visible components, not those of the full view.
10045 (Try_Primitive_Operation): If the operation is a procedure, collect all
10046 possible interpretations, as for a function, because in the presence of
10047 classwide parameters several primitive operations of the type can match
10048 the given arguments.
10050 2007-04-06 Ed Schonberg <schonberg@adacore.com>
10051 Robert Dewar <dewar@adacore.com>
10053 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
10054 tag-indeterminate call to an abstract function, when the left-hand side
10056 (Analyze_Loop_Statement): Improve detection of infinite loops
10058 2007-04-06 Ed Schonberg <schonberg@adacore.com>
10059 Thomas Quinot <quinot@adacore.com>
10061 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
10062 out of Analyze_Package_Declaration, because processing must be applied
10063 to package bodies as well, for deferred constants completed by pragmas.
10064 (Analyze_Package_Declaration): When the package declaration being
10065 analyzed does not require an explicit body, call Check_Completion.
10066 (May_Need_Implicit_Body): An implicit body is required when a package
10067 spec contains the declaration of a remote access-to-classwide type.
10068 (Analyze_Package_Body): If the package contains RACWs, append the
10069 pending subprogram bodies generated by exp_dist at the end of the body.
10070 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
10071 Is_Abstract_Subprogram and Is_Abstract_Type.
10072 (Preserve_Full_Attributes): The full entity list is not an attribute
10073 that must be preserved from full to partial view.
10075 * sem_dist.adb (Add_RAS_Dereference_TSS):
10076 Change primitive name to _Call so it cannot clash with any legal
10077 identifier, and be special-cased in Check_Completion.
10078 Mark the full view of the designated type for the RACW associated with
10079 a RAS as Comes_From_Source to get proper view switching when installing
10080 private declarations.
10081 Provite a placeholder nested package body along with the nested spec
10082 to have a place for Append_RACW_Bodies to generate the calling stubs
10083 and stream attributes.
10085 2007-04-06 Ed Schonberg <schonberg@adacore.com>
10086 Robert Dewar <dewar@adacore.com>
10088 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
10089 that is a limited view, check the non-limited view if available.
10090 (Undefined): Refine error message for missing with of Text_IO
10091 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
10092 to distinguish real missing with cases.
10093 Fix format of all missing with messages
10094 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
10095 renaming as body when renamed entity is abstract.
10097 2007-04-06 Ed Schonberg <schonberg@adacore.com>
10098 Javier Miranda <miranda@adacore.com>
10100 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
10101 predicate recursive, to handle complex expressions on literals whose
10102 spurious ambiguity comes from the abstract interpretation of some
10104 (Interface_Present_In_Ancestor): Add support to concurrent record
10106 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
10107 Is_Abstract_Subprogram and Is_Abstract_Type.
10109 2007-04-06 Ed Schonberg <schonberg@adacore.com>
10110 Javier Miranda <miranda@adacore.com>
10112 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
10113 dereference of a local object R created as a reference to another
10114 object O, use the access level of O.
10115 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
10116 rather than local Same_Formal_Type, to check whether protected operation
10117 overrides an inherited one.
10118 (Same_Formal_Type): New predicate, used when matching signatures of
10119 overriding synchronized operations, to handle the case when a formal
10120 has a type that is a generic actual.
10121 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
10122 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
10123 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
10124 syntactic ambiguities involving indexing of function calls that return
10126 (Abstract_Interface_List): New subprogram that returns the list of
10127 abstract interfaces associated with a concurrent type or a
10128 concurrent record type.
10129 (Interface_Present_In_Parent): New subprogram used to check if a
10130 given type or some of its parents implement a given interface.
10131 (Collect_Abstract_Interfaces): Add support for concurrent types
10132 with interface types.
10133 (Has_Abstract_Interfaces): Add support for concurrent types with
10135 (Is_Parent): New subprogram that determines whether E1 is a parent
10136 of E2. For a concurrent type its parent is the first element of its
10137 list of interface types; for other types this function provides the
10138 same result than Is_Ancestor.
10139 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
10140 (Collect_Synchronized_Interfaces): Removed because the subprogram
10141 Collect_Abstract_Interfaces provides this functionality.
10142 (Collect_Abstract_Interfaces): Minor update to give support to
10143 concurrent types and thus avoid undesired code duplication.
10144 (Get_Subprogram_Entity): Handle entry calls.
10145 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
10147 (Enter_Name): Do not give -gnatwh hiding warning for record component
10148 entities, they never result in hiding.

10151 Robert Dewar <dewar@adacore.com>
10153 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,

10155 of the enclosing object.
10156 Add N_Push and N_Pop nodes
10157 New field Exception_Label added
10158 (Local_Raise_Statements): New field in N_Exception_Handler_Node
10159 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

10163 can be an E_Return_Statement.
10164 (Is_Coextension): New flag for allocators.
10165 Remove all code for DSP option

10173 before propagating exception.
10175 2007-04-06 Olivier Hainque <hainque@adacore.com>
10177 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
10178 an address always within the call instruction from a return address.
10180 2007-04-06 Olivier Hainque <hainque@adacore.com>
10181 Eric Botcazou <botcazou@adacore.com>
10183 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
10184 expression with a COMPOUND_EXPR including the call instead of emitting
10185 the call directly here.
10186 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
10187 high bound is constant and the slice is empty. Tidy.
10188 (tree_transform, case N_Op_Not): Handle properly the case where the
10189 operation applies to a private type whose full view is a modular type.
10190 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
10191 Address_Clause, use the associated Expression as the GNAT tree
10192 representing the choice value to ensure the corresponding GCC tree is
10193 of the proper kind.
10194 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
10195 instead of just the operands, as the base GCC stabilize_reference does.
10196 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
10197 requested; otherwise fail.
10198 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

10203 implementation of UI_Div.
10204 (UI_Div): Reimplement as a call to UI_Div_Rem.
10205 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
10206 remainder, avoiding the cost of a multiplication and a subtraction.
10207 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
10208 provides both quotient and remainder in a single computation.
10209 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
10210 functions for uint.
10211 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

10231 builtin_decls list.
10232 (gnat_install_builtins): Adjust comments.
10233 (builtin_function): Set DECL_BUILTIN_CLASS and DECL_FUNCTION_CODE before
10234 calling gnat_pushdecl, so that it knows when it handed a builtin
10235 function declaration node.

10458 (mainly static expression evaluation).
10459 Reword some continuation messages
10460 Add some \\ sequences to continuation messages
10461 (Resolve_Call): Refine infinite recursion case. The test has been

10478 anonymous access types.
10479 (Valid_Conversion): For a conversion to a numeric type occurring in an
10480 instance or inlined body, no need to check that the operand type is
10481 numeric, since this has been checked during analysis of the template.

10947 (__gnat_set_globals): Now a dummy function.
10948 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
10949 mechargs instead of sigargs, as the latter can be retrieved from the

10996 sem_util and renamed as Collect_All_Abstract_Interfaces.
10997 (Set_All_DT_Position): Hidden entities associated with abstract
10998 interface primitives are not taken into account in the check for

11011 (Make_DT): If the ancestor of the type is a CPP_Class and we are
11012 compiling under full ABI compatibility mode we avoid the generation of
11013 calls to run-time services that fill the dispatch tables because under
11014 this mode we currently inherit the dispatch tables in the IP subprogram.
11015 (Write_DT): Emit an "is null" indication for a null procedure primitive.
11016 (Expand_Interface_Conversion): Use an address as the type of the formal

11068 we request a discriminal value only in case of discriminants.
11069 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
11070 assignments where the target subtype is unconstrained and the target
11071 object is a parameter or dereference (other aliased cases are known

11189 (Replace_Self_Reference): New subsidiary of
11190 Make_OK_Assignment_Statement, to replace an access attribute that is a
11191 self-reference into an access to the appropriate component of the

11193 nested at any level.
11194 (Is_Self_Referential_Init): Remove, not needed.

11203 Typ'Acc, where Acc is an access attribute, the expression comes from a
11204 default initialized self-referential component.

11206 that has been derived from several abstract interfaces we must also

11212 Robert Dewar <dewar@adacore.com>
11215 (Expand_Access_To_Protected_Op): If the context indicates that an access

11235 subcomponent's enclosing variable is aliased with a constrained subtype.
11236 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
11237 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
11238 an aliased prefix must be known to be constrained in order to use True
11239 for the attribute value, and now it's possible for some aliased views
11240 to be unconstrained.

11255 otherwise we incorrectly register the tag of the interface in the final
11257 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
11258 generate the wrapper if the parent primitive is abstract. This is
11259 required to report the correct error message.
11260 (Expand_N_Subtype_Indication): Do validity checks on range
11261 (Clean_Task_Names): If an initialization procedure includes a call to
11262 initialize a task (sub)component, indicate that the procedure will use

11270 call to build-in-place function and apply Make_Build_In_Place_Call_In_
11271 Object_Declaration to the call.
11272 (Freeze_Type): When the designated type of an RACW was not frozen at the
11273 point where the RACW was declared, validate the primitive operations
11274 with respect to E.2.2(14) when it finally is frozen.
11275 (Build_Initialization_Call,Expand_Record_Controller): Rename
11276 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
11277 return-by-reference has no meaning in Ada 2005.
11278 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
11279 to register tag of the immediate ancestor interfaces in the
11280 run-time structure.
11281 (Init_Secondary_Tags): Moved to the specification to allow the
11282 initialization of extension aggregates with abstract interfaces.
11283 (Build_Master_Renaming): Make public, for use by function declarations
11284 whose return type is an anonymous access type.
11285 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
11286 Insert_List_Before_And_Analyze after the generation of the specs
11287 associated with null procedures.
11288 (Expand_Tagged_Root): Update documentation in its specification.
11289 (Init_Secondary_Tags): Update documentation.
11290 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
11291 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
11292 then generate code to inherit the contents of the dispatch table
11293 directly from the ancestor.
11294 (Expand_Record_Controller): Insert controller component after tags of
11295 implemented interfaces.
11296 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to

11300 declarations for overriding null primitives inherited from interfaces.
11301 (Is_Null_Interface_Procedure): New function in
11302 Make_Null_Procedure_Specs.
11303 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
11304 immediate ancestor of a tagged type is an abstract interface type we
11305 must generate the specification of the predefined primitives associated
11306 with controlled types (because the dispatch table of the ancestor is
11307 null and hence these entries cannot be inherited). This is required to
11308 elaborate well the dispatch table.

11322 the maximum for type T.
11323 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
11324 when the allocator is initialized by a build-in-place call, since the
11325 allocator is already rewritten as a reference to the function result,
11326 and this prevents an unwanted duplication of the function call.
11327 Add with and use of Exp_Ch6.
11328 (Expand_Allocator_Expresssion): Check for an allocator whose expression
11329 is a call to build-in-place function and apply
11330 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
11331 untagged designated types).
11332 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
11333 optimization if source or target is biased.
11334 (Expand_N_Allocator): Add comments for case of an allocator within a
11335 function that returns an anonymous access type designating tasks.
11336 (Expand_N_Allocator): apply discriminant checks for access
11337 discriminants of anonymous access types (AI-402, AI-416)
11339 2006-10-31 Bob Duff <duff@adacore.com>
11340 Robert Dewar <dewar@adacore.com>
11341 Gary Dismukes <dismukes@adacore.com>
11342 Ed Schonberg <schonberg@adacore.com>
11344 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
11346 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
11347 (Expand_N_Assignment_Statement): Call
11348 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
11349 build-in-place function call. Currently, this can happen only for
11350 assignments that come from aggregates.
11351 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11352 in order to alleviate the upward compatibility introduced by AI-318.
11353 (Expand_N_Extended_Return_Statement): Add support for handling the
11354 return object as a build-in-place result.
11355 (Expand_Non_Function_Return): Implement simple return statements nested
11356 within an extended return.
11357 (Enable_New_Return_Processing): Turn on the new processing of return
11359 (Expand_Non_Function_Return): For a return within an extended return,
11360 don't raise Program_Error, because Sem_Ch6 now gives a warning.
11361 (Expand_N_Extended_Return_Statement): Implement AI-318
11362 (Expand_Simple_Function_Return): Ditto.
11363 (Expand_N_If_Statement): Handle new -gnatwt warning
11364 (Expand_N_Case_Statement): Handle new -gnatwt warning
11365 (Expand_N_Assignment): Handle assignment to the Priority attribute of
11366 a protected object.
11367 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
11368 validity checking of assignments to elementary record components.
11369 (Expand_N_Return_Statement): return Class Wide types on the secondary
11370 stack independantly of their controlled status since with HIE runtimes,
11371 class wide types are not potentially controlled anymore.
11373 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
11376 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
11377 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
11378 it expects a block, procedure, or task. The return statement will get
11379 turned into a block, and Expand_Cleanup_Actions will happen then.
11381 2006-10-31 Robert Dewar <dewar@adacore.com>
11382 Ed Schonberg <schonberg@adacore.com>
11383 Bob Duff <duff@adacore.com>
11384 Gary Dismukes <dismukes@adacore.com>
11386 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
11388 (Expand_Inlined_Call): Tagged types are by-reference types, and
11389 therefore should be replaced by a renaming declaration in the expanded
11390 body, as is done for limited types.
11391 (Expand_Call): If this is a call to a function with dispatching access
11392 result, propagate tag from context.
11393 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
11395 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
11396 build-in-place when the right-hand side of an assignment is a
11397 build-in-place function call.
11398 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
11399 of the explicit dereference of the allocator to the result subtype of
11400 the build-in-place function. This is needed to satisfy type checking
11401 in cases where the caller's return object is created by an allocator for
11402 a class-wide access type and the type named in the allocator is a
11404 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
11405 conversion of the reference to the declared object to the result subtype
11406 of the build-in-place function. This is needed to satisfy type checking
11407 in cases where the declared object has a class-wide type. Also, in the
11408 class-wide case, change the type of the object entity to the specific
11409 result subtype of the function, to avoid passing a class-wide object
11410 without explicit initialization to the back end.
11411 (Register_Interface_DT_Entry): Moved outside the body of
11412 Freeze_Subprogram because this routine is now public; it is called from
11413 Check_Dispatching_Overriding to handle late overriding of abstract
11414 interface primitives.
11415 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
11416 adding an implicit access actual on a call to a build-in-place function.
11417 (Expand_Actuals): Test for an actual parameter that is a call to a
11418 build-in-place function and apply
11419 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
11420 (Is_Build_In_Place_Function): New function to determine whether an
11421 entity is a function whose calls should be handled as build-in-place.
11422 (Is_Build_In_Place_Function_Call): New function to determine whether an
11423 expression is a function call that should handled as build-in-place.
11424 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
11425 calls to build-in-place functions as the initialization of an allocator.
11426 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
11427 handling calls to build-in-place functions in contexts that do not
11428 involve init of a separate object (for example, actuals of subprogram
11430 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
11431 handling calls to build-in-place functions as the initialization of an
11432 object declaration.
11433 (Detect_Infinite_Recursion): Add explicit parameter Process to
11434 instantiation of Traverse_Body to avoid unreferenced warning.
11435 (Check_Overriding_Inherited_Interfaces): Removed.
11436 (Register_Interface_DT_Entry): Code cleanup.
11437 (Register_Predefined_DT_Entry): Code cleanup.
11438 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
11439 inlined statements if within a transient scope.
11440 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
11441 formal parameters with occurrences of actuals in inlined body, establish
11442 visibility on the proper view of the actual's subtype for the body's
11444 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
11445 compatibility mode and we have an imported CPP subprogram because
11446 for now we assume that imported CPP primitives correspond with
11447 objects whose constructor is in the CPP side (and therefore we
11448 don't need to generate code to register them in the dispatch table).
11449 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
11450 aligned selected component.
11451 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
11452 the actual of an in-mode parameter is a type conversion.
11453 (Expand_Actuals): If the call does not come from source and the actual
11454 is potentially misaligned, let gigi handle it rather than rejecting the
11455 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
11456 Class Wide types as returning by reference independantly of their
11457 controlled status since with HIE runtimes class wide types are not
11458 potentially controlled anymore.
11460 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11462 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
11463 references that are private components of the protected object.
11464 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
11465 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
11466 instantiation to deal with warnings.
11467 (Initialize_Protection): If expression for priority is non-static, use
11468 System_Priority as its expected type, in case the expression has not
11471 2006-10-31 Robert Dewar <dewar@adacore.com>
11473 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
11474 initialization of Homonym_Len.
11475 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
11476 names from fully qualified name. Fixes problem of duplicate
11477 external names differing only in the presence of such a block name.
11479 2006-10-31 Thomas Quinot <quinot@adacore.com>
11480 Pablo Oliveira <oliveira@adacore.com>
11482 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
11483 subprogram Ids, even if they are not yet assigned.
11484 (Build_Subprogram_Id): It is now this function that will take care of
11485 calling Assign_Subprogram_Ids if necessary.
11486 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
11487 should be done only once they are assigned.
11488 (Build_From_Any_Function, case of tagged types): Add missing call to
11490 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
11491 type for an RACW type.
11492 (Add_RACW_Features): When processing an RACW declaration for which the
11493 designated type is already frozen, enforce E.2.2(14) rules immediately.
11494 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
11495 special reordering of controlling formals.
11497 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
11498 associated stub type for an RACW type.
11500 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11502 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
11503 fixed-point operations in an integer context, i.e. as operands of a
11504 conversion to an integer type, indicate that result must be rounded.
11506 2006-10-31 Robert Dewar <dewar@adacore.com>
11508 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
11509 cases, pass the encoding method, since it is now required by the run
11512 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
11513 assumption that Str'First = 1.
11514 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
11515 it on to the Value_Wide_Wide_Character call.
11516 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
11517 properly handles a string of the form quote-encoded_wide_char-quote.
11519 * s-wchcnv.adb: Minor reformatting
11521 2006-10-31 Javier Miranda <miranda@adacore.com>
11523 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
11524 run-time membership test to ensure that the constructed object
11525 implements the target abstract interface.
11527 2006-10-31 Robert Dewar <dewar@adacore.com>
11529 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
11530 Machine_Attribute pragma internally to implement the user pragma.
11531 Add processing for pragma Interface so that it is now completely
11532 equivalent to pragma Import.
11534 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
11535 so that it can be applied to all entities, including record components
11536 and enumeration literals.
11537 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
11538 priority ranges are correct, verify compatibility against task
11539 dispatching and locking policies, and if everything is correct an entry
11540 is added to the table containing priority specific dispatching entries
11541 for this compilation unit.
11542 (Delay_Config_Pragma_Analyze): Delay processing
11543 Priority_Specific_Dispatching pragmas because when processing the
11544 pragma we need to access run-time data, such as the range of
11545 System.Any_Priority.
11546 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
11547 Allow pragma Unreferenced as a context item
11548 Add pragma Preelaborable_Initialization
11549 (Analyze_Pragma, case Interface): Interface is extended so that it is
11550 now syntactically and semantically equivalent to Import.
11551 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
11552 insertion characters.
11553 Add handling for Pragma_Wide_Character_Encoding
11554 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
11555 never supercedes a real restriction, and that a real restriction
11556 always supercedes a warning.
11557 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

11561 Ed Schonberg <schonberg@adacore.com>
11562 Robert Dewar <dewar@adacore.com>
11564 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
11565 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
11566 Is_Inherently_Limited_Type, because return-by-reference has no meaning
11568 (Find_Node_To_Be_Wrapped): Use new method of determining the result
11569 type of the function containing a return statement, because the
11570 Return_Type field was removed. We now use the Return_Applies_To field.
11572 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
11573 (Build_Task_Image_Decl): If procedure is not called from an
11574 initialization procedure, indicate that function that builds task name
11575 uses the sec. stack. Otherwise the enclosing initialization procedure
11576 will carry the indication.
11577 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
11578 N_Object_Declaration instead.
11579 (Kill_Dead_Code): New interface to implement -gnatwt warning for
11580 conditional dead code killed, and change implementation accordingly.
11581 (Insert_Actions): Add N_Return_Object_Declaration case.
11582 Correct comment to mention N_Extension_Aggregate node.
11583 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
11584 attempts to save information for global variables which cannot be
11586 (Get_Current_Value_Condition): Handle conditions the other way round
11587 (constant on left). Also handle right operand of AND and AND THEN
11588 (Set_Current_Value_Condition): Corresponding changes
11589 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
11590 (Get_Current_Value_Condition): Handle simple boolean operands
11591 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
11592 (Get_Current_Value_Condition): If the variable reference is within an
11593 if-statement, does not appear in the list of then_statments, and does
11594 not come from source, treat it as being at unknown location.
11595 (Get_Current_Value_Condition): Enhance to allow while statements to be
11596 processed as well as if statements.
11597 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
11599 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
11600 of loop. This is safe now that we fixed Kill_Current_Values.
11601 (OK_To_Do_Constant_Replacement): Check whether current scope is
11602 Standard, before examining outer scopes.
11604 2006-10-31 Vincent Celier <celier@adacore.com>
11606 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
11607 When True, apply VMS treatment to children of packages A, G, I and S.
11610 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
11612 2006-10-31 Robert Dewar <dewar@adacore.com>
11613 Ed Schonberg <schonberg@adacore.com>
11615 * freeze.adb: Add handling of Last_Assignment field
11616 (Warn_Overlay): Supply missing continuation marks in error msgs
11617 (Freeze_Entity): Add check for Preelaborable_Initialization
11619 * g-comlin.adb: Add Warnings (Off) to prevent new warning
11621 * g-expect.adb: Add Warnings (Off) to prevent new warning
11623 * lib-xref.adb: Add handling of Last_Assignment field
11624 (Generate_Reference): Centralize handling of pragma Obsolescent here
11625 (Generate_Reference): Accept an implicit reference generated for a
11626 default in an instance.
11627 (Generate_Reference): Accept a reference for a node that is not in the
11628 main unit, if it is the generic body corresponding to an subprogram
11631 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
11633 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
11635 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
11637 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
11638 use clauses, to avoid messages on packages used to qualify, and also
11639 to avoid messages from obsolescent units.
11640 (Warn_On_Useless_Assignments): Don't generate messages for imported
11641 and exported variables.
11642 (Warn_On_Useless_Assignments): New procedure
11643 (Output_Obsolescent_Entity_Warnings): New procedure
11644 (Check_Code_Statement): New procedure
11646 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
11647 Change name Is_Ada_2005 to Is_Ada_2005_Only
11648 (Last_Assignment): New field for useless assignment warning
11650 2006-10-31 Olivier Hainque <hainque@adacore.com>
11652 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
11653 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
11655 2006-10-31 Bob Duff <duff@adacore.com>
11656 Robert Dewar <dewar@adacore.com>
11657 Ed Schonberg <schonberg@adacore.com>
11659 * g-awk.adb (Default_Session, Current_Session): Compile this file in
11660 Ada 95 mode, because it violates the new rules for AI-318.
11662 * g-awk.ads: Use overloaded subprograms in every case where we used to
11663 have a default of Current_Session. This makes the code closer to be
11664 correct for both Ada 95 and 2005.
11666 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
11667 code, relying on the fact that the compiler generates a warning
11668 instead of an error in -gnatg mode.
11670 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
11671 E_Return_Statement entity kind.
11672 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
11674 * par.adb (P_Interface_Type_Definition): Addition of one formal to
11675 report an error if the reserved word abstract has been previously found.
11676 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
11678 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
11679 parenthesized range attribute usage
11680 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
11682 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
11683 in the syntax for extended_return_statement. This is not in the latest
11684 RM, but the ARG is expected to issue an AI allowing this.
11685 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
11686 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
11687 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
11688 P_Return_Statement): Parse the new syntax for extended_return_statement.
11690 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
11691 Output_End_Missing): Add error-recovery code for the new
11692 extended_return_statement syntax; that is, the new E_Return entry on
11695 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
11696 limited to nonlimited, because otherwise we violate the new Ada 2005
11697 rules about returning limited types in function Create_AST_Handler in
11700 * sem.adb (Analyze): Add cases for new node kinds
11701 N_Extended_Return_Statement and N_Return_Object_Declaration.
11703 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
11704 type is in the same category as type of context before applying check,
11705 to prevent anomalies in instantiations.
11706 (Resolve_Aggregate): Remove test for limited components in aggregates.
11707 It's unnecessary in Ada 95, because if it has limited components, then
11708 it must be limited. It's wrong in Ada 2005, because limited aggregates
11710 (Resolve_Record_Aggregate): Move check for limited types later, because
11711 OK_For_Limited_Init requires its argument to have been resolved.
11712 (Get_Value): When copying the component default expression for a
11713 defaulted association in an aggregate, use the sloc of the aggregate
11714 and not that of the original expression, to prevent spurious
11715 elaboration errors, when the expression includes function calls.
11716 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
11717 were missing. We also didn't handle qualified expressions. Now also
11718 allow function calls. Use new common routine OK_For_Limited_Init.
11719 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
11720 with space can upper case letter).
11722 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
11723 Has_Static_Discriminants flag
11724 (Record_Type_Declaration): Diagnose an attempt to declare an interface
11725 type with discriminants.
11726 (Process_Range_Expr_In_Decl): Do validity checks on range
11727 (Build_Discriminant_Constraints): Use updated form of
11728 Denotes_Discriminant.
11729 (Process_Subtype): If the subtype is a private subtype whose full view
11730 is a concurrent subtype, introduce an itype reference to prevent scope
11732 (Build_Derived_Record_Type, Collect_Interface_Primitives,
11733 Record_Type_Declaration): The functionality of the subprograms
11734 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
11735 is now performed by a single routine.
11736 (Build_Derived_Record_Type): If the type definition includes an explicit
11737 indication of limitedness, then the type must be marked as limited here
11738 to ensure that any access discriminants will not be treated as having
11739 a local anonymous access type.
11740 (Check_Abstract_Overriding): Issue a detailed error message when an
11741 abstract subprogram was not overridden due to incorrect mode of its
11743 (Analyze_Private_Extension_Declaration): Add support for the analysis of
11744 synchronized private extension declarations. Verify that the ancestor is
11745 a limited or synchronized interface or in the generic case, the ancestor
11746 is a tagged limited type or synchronized interface and all progenitors
11747 are either limited or synchronized interfaces.
11748 Derived_Type_Declaration): Check for presence of private extension when
11749 dealing with synchronized formal derived types.
11750 Process_Full_View): Enchance the check done on the usage of "limited" by
11751 testing whether the private view is synchronized.
11752 Verify that a synchronized private view is completed by a protected or
11754 (OK_For_Limited_Init_In_05): New function.
11755 (Analyze_Object_Declaration): Move check for limited types later,
11756 because OK_For_Limited_Init requires its argument to have been resolved.
11757 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11758 in order to alleviate the upward compatibility introduced by AI-318.
11759 (Constrain_Corresponding_Record): If the constraint is for a component
11760 subtype, mark the itype as frozen, to avoid out-of-scope references to
11761 discriminants in the back-end.
11762 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
11763 this subprogram against wrong sources.
11764 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
11765 discriminant of limited type completed with a protected type, when the
11766 discriminant is used to constrain a private component of the type, and
11767 expansion is disabled.
11768 (Find_Type_Of_Object): Do not treat a return subtype that is an
11769 anonymous subtype as a local_anonymous_type, because its accessibility
11770 level is the return type of the enclosing function.
11771 (Check_Initialization): In -gnatg mode, turn the error "cannot
11772 initialize entities of limited type" into a warning.
11773 (OK_For_Limited_Init): Return true for generated nodes, since it
11774 sometimes violates the legality rules.
11775 (Make_Incomplete_Declaration): If the type for which an incomplete
11776 declaration is created happens to be the currently visible entity,
11777 preserve the homonym chain when removing it from visibility.
11778 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
11779 inherited subprograms.
11780 (Access_Definition): If this is an access to function that is the return
11781 type of an access_to_function definition, context is a type declaration
11782 and the scope of the anonymous type is the current one.
11783 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
11784 incomplete subtype to the set of private dependents of the original
11786 (Constrain_Discriminated_Type): Emit an error message whenever an
11787 incomplete subtype is being constrained.
11788 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
11789 corresponding subtype of the full view of the original incomplete type.
11790 (Check_Incomplete): Properly detect invalid usage of incomplete types

11804 Robert Dewar <dewar@adacore.com>
11806 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
11807 handling executable extension manually and duplicating code.
11809 * make.adb: Implement new -S switch
11810 (Gnatmake): Use new function Osint.Executable_Name instead
11811 of handling executable extension manually.
11813 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
11814 is specified, the executable name ends with this suffix.
11815 Take advantage of Osint.Executable_Name instead of duplicating code.
11817 * switch-m.adb: Recognize new gnatmake -S switch
11819 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
11821 (Get_Target_Parameters): Set Executable_Extension_On_Target if
11824 * makeusg.adb: Add line for gnatmake -S switch
11826 2006-10-31 Vincent Celier <celier@adacore.com>
11828 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
11829 call it with -static-libgcc, as there are some platforms, such as
11830 Darwin, where one of these two switches is compulsory to link.
11832 2006-10-31 Vincent Celier <celier@adacore.com>
11834 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
11835 instead of ADA_PROJECT_PATH, for the project path.
11836 (Gnatls): When displaying the project path directories, use host dir
11839 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
11840 names in the project path, as absolute paths may correspond to
11841 multi-valued VMS logical names.
11843 2006-10-31 Vincent Celier <celier@adacore.com>
11845 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
11846 absolute path name.
11847 (Locate_Regular_File): Ditto
11848 (Change_Dir): Remove, no longer used
11849 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
11850 on Windows. Get it calling Get_Current_Dir.
11851 (OpenVMS): Remove imported boolean, no longer needed.
11852 (Normalize_Pathname)[VMS]: Do not resolve directory names.
11853 (Pid_To_Integer): New function to convert a Process_Id to Integer
11855 2006-10-31 Thomas Quinot <quinot@adacore.com>

11860 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
11863 2006-10-31 Robert Dewar <dewar@adacore.com>
11865 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
11866 initial letter o as a zero.

11870 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
11872 2006-10-31 Robert Dewar <dewar@adacore.com>
11874 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
11876 (Layout_Variant_Record): Retrieve the discriminants from the entity
11877 rather than from the type definition, because in the case of a full
11878 type for a private type we need to take the discriminants from the
11880 (Layout_Component_List): When applying the Max operator to variants with
11881 a nonstatic size, check whether either operand is static and scale that
11882 operand from bits to storage units before applying Max.
11883 (Layout_Type): In VMS, if a C-convention access type has no explicit
11884 size clause (and does not inherit one in the case of a derived type),
11885 then the size is reset to 32 from 64.
11887 2006-10-31 Vincent Celier <celier@adacore.com>
11889 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
11890 its file has already been loaded, according to the unit being loaded,
11891 not to the current value of Multiple_Unit_Index.
11893 2006-10-31 Thomas Quinot <quinot@adacore.com>
11894 Eric Botcazou <ebotcazou@adacore.com>
11895 Arnaud Charlet <charlet@adacore.com>
11897 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
11898 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
11900 (a-except.o): Pass it to the compiler.
11901 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.

11919 2006-10-31 Vincent Celier <celier@adacore.com>
11921 * mlib-utl.adb (Initialized): Remove, no longer used
11922 (Initialize): Remove, no longer used
11923 (Ar): If Ar_Exec is null, get the location of the archive builder and,
11924 if there is one, the archive indexer. Fail if the archive builder cannot
11926 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
11929 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11931 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
11932 Process_Body_Clauses): If the context of a body includes a use clause
11933 for P.Q then a with_clause for P in the same body is not redundant,
11934 even if the spec also has a with_clause on P.
11935 Add missing continuation mark to error msg
11936 (Build_Limited_Views): A limited view of a type is tagged if its
11937 declaration includes a record extension.
11938 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
11939 node, even if the subunit has errors. This avoids malfunction by
11940 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
11941 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
11942 generation of obsolescent messages for with statements (cannot do
11943 this too early, or we cannot implement avoiding the messages in the
11944 case of obsolescent units withing obsolescent units).
11945 (Install_Siblings): If the with_clause is on a remote descendant of
11946 an ancestor of the current compilation unit, find whether there is
11947 a sibling child unit that is immediately visible.
11948 (Remove_Private_With_Clauses): New procedure, invoked after completing
11949 the analysis of the private part of a nested package, to remove from
11950 visibility the private with_clauses of the enclosing package
11952 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
11953 now centralized in Generate_Reference.
11954 (Install_Limited_Context_Clauses): Remove superfluous error
11955 message associated with unlimited view visible through use
11956 and renamings. In addition, at the point in which the error
11957 is reported, we add the backslash to the text of the error
11958 to ensure that it is reported as a single error message.
11959 Use new // insertion for some continuation messages
11960 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
11961 to create implicit with_clause for parent unit mentioned in original
11962 limited_with_clause.
11963 (Install_Limited_With_Unit): Set entity of parent identifiers if the
11964 unit is a child unit. For ASIS queries.
11965 (Analyze_Subunit): If the subunit appears within a child unit, make all
11966 ancestor child units directly visible again.

11981 a formal object declaration with an access definition or a subtype mark
11982 with a null exclusion.
11983 (P_Generic_Association): Handle association with box, and others_choice
11984 with box, to support Ada 2005 partially parametrized formal packages.
11986 2006-10-31 Robert Dewar <dewar@adacore.com>
11987 Javier Miranda <miranda@adacore.com>
11989 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
11990 (P_Type_Declaration): Remove barrier against the reserved word "limited"
11991 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
11992 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
11993 private extensions.
11994 (P_Type_Declaration): Add the new actual Abstract_Present to every call
11995 to P_Interface_Type_Definition.
11996 (P_Interface_Type_Definition): Addition of one formal to report an error
11997 if the reserved word abstract has been previously found.
11998 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
11999 object renaming declaration with an access definition or subtype mark
12000 with a possible null exclusion.
12002 * par-ch9.adb: Minor error msg fix
12004 * par-load.adb: Add missing continuation mark to error msg
12006 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation
12008 2006-10-31 Vincent Celier <celier@adacore.com>
12010 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
12011 unknown attribute in unknown package or in package that does not need
12013 (Parse_Package_Declaration): Do not issue warning for unknown package in
12016 2006-10-31 Vincent Celier <celier@adacore.com>
12018 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
12019 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
12022 2006-10-31 Vincent Celier <celier@adacore.com>
12024 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
12025 on VMS, change "__" to '.' before checking the name.
12026 (Record_Ada_Source): Always add the source file name in the list of
12027 of sources, even if it is not the first time, as it is for another
12029 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
12030 dot, instead of replacing only the first '_'.
12032 * prj-part.adb (Parse): Convert project file path to canonical form
12034 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
12035 extended, the project id of the project extending it is recorded in its
12036 data, even when it has already been processed as an imported project.
12038 2006-10-31 Robert Dewar <dewar@adacore.com>
12040 * repinfo.adb (List_Entities): Don't list entities from renaming
12043 2006-10-31 Arnaud Charlet <charlet@adacore.com>
12044 Robert Dewar <dewar@adacore.com>
12046 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
12047 only a restriction warning is active for the given restriction. This is
12048 desirable because we do not want to modify code in the case where only
12050 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
12051 causes overriding of real restrictions.
12052 Take advantage of new No_Restrictions constant.
12054 * raise.h: (__gnat_set_globals): Change profile.
12056 2006-10-31 Arnaud Charlet <charlet@adacore.com>
12058 * rtsfind.adb: Remove s-polint from comment as it exists no more.
12061 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
12062 Move all the entities in obsolete package System.PolyORB_Interface to
12063 System.Partition_Interface.
12064 (RE_Storage_Size): New function in System.Tasking.
12065 (RE_Get_Ceiling): New entity.

12074 starting with a digit.
12076 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12077 Thomas Quinot <quinot@adacore.com>
12078 Javier Miranda <miranda@adacore.com>
12079 Gary Dismukes <dismukes@adacore.com>
12081 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
12082 properly an attempt to apply Unchecked_Access to a protected operation.
12083 (OK_Self_Reference): New subprogram to check the legality of an access
12084 attribute whose prefix is the type of an enclosing aggregate.
12085 Generalizes previous mechanism to handle attribute references nested
12086 arbitrarily deep within the aggregate.
12087 (Analyze_Access_Attribute): An access attribute whose prefix is a type
12088 can appear in an aggregate if this is a default-initialized aggregate
12089 for a self-referential type.
12090 (Resolve_Attribute, case Access): Ditto.
12091 Add support for new implementation defined attribute Stub_Type.
12092 (Eval_Attribute, case Attribute_Stub_Type): New case.
12093 (Analyze_Attribute, case Attribute_Stub_Type): New case.
12094 (Stream_Attribute_Available): Implement using new subprogram from
12095 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
12096 Has_Specified_Stream_Attribute flag.
12097 Disallow Storage_Size and Storage_Pool for access to subprogram
12098 (Resolve_Attribute, case 'Access et al): Take into account anonymous
12099 access types of return subtypes in extended return statements. Remove
12100 accessibility checks on anonymous access types when Unchecked_Access is
12102 (Analyze_Attribute): Add support for the use of 'Class to convert
12103 a class-wide interface to a tagged type.
12104 Add support for the attribute Priority.
12105 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
12106 whether the designated type is discriminated with a constrained partial
12107 view and require static matching in that case.
12108 Add local variable Des_Btyp. The Designated_Type
12109 of an access to incomplete subtype is either its non-limited view if
12110 coming from a limited with or its etype if regular incomplete subtype.
12112 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
12113 Fix predicate to identify and allow cases of (expander-generated)
12114 references to tag of designated object of a RACW.
12115 (Validate_Static_Object_Name): In Ada 2005, a formal object is
12116 non-static, and therefore cannot appear as a primary in a preelaborable
12118 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
12119 Has_Read_Write_Attributes.
12120 (Has_Read_Write_Attributes): Reimplement in termes of
12121 Has_Stream_Attribute_Definition.
12122 (Missing_Read_Write_Attributes): When checking component types in a
12123 record, unconditionally call Missing_Read_Write_Attributes recursively
12124 (remove guard checking for Is_Record_Type / Is_Access_Type).
12126 2006-10-31 Robert Dewar <dewar@adacore.com>
12128 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
12129 useless assignments here and conditionalize it on absence of exception
12131 (Analyze_Exception_Handlers): Small code reorganization of error
12132 detection code, for new handling of formal packages.
12134 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12135 Hristian Kirtchev <kirtchev@adacore.com>
12137 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
12138 that has been constant-folded, preserve information of original tree,
12140 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
12141 generated private extension declaration if the formal derived type is
12142 synchronized. Carry synchronized present over to the generated private
12144 (Validate_Derived_Type_Instance): Ensure that the actual of a
12145 synchronized formal derived type is a synchronized tagged type.
12146 (Instantiate_Formal_Package): When creating the instantiation used to
12147 validate the actual package of a formal declared without a box, check
12148 whether the formal itself depends on a prior actual.
12149 (Instantiate_Formal_Subprogram): Create new entities for the defining
12150 identifiers of the formals in the renaming declaration, for ASIS use.
12151 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
12152 a renaming declaration or a subtype declaration for an actual in an
12153 instance, capture location information of declaration in generic, for
12155 (Instantiate_Formal_Package): Add comments on needed additional tests.
12156 AI-317 (partial parametrization) is fully implemented.
12157 (Validate_Private_Type_Instance): Add check for actual which
12158 must have preelaborable initialization
12159 Use new // insertion for some continuation messages
12160 (Analyze_Formal_Object_Declaration): Change usage of Expression to
12161 Default_Expression. Add type retrieval when the declaration has an
12162 access definition. Update premature usage of incomplete type check.
12163 (Check_Access_Definition): New subsidiary routine. Check whether the
12164 current compilation version is Ada 05 and the supplied node has an
12166 (Instantiate object): Alphabetize local variables. Handle the creation
12167 of new renaming declarations with respect to the kind of definition
12168 used - either an access definition or a subtype mark. Guard against
12169 unnecessary error message in the context of anonymous access types after
12170 they have been resolved. Add check for required null exclusion in a
12171 formal object declaration.
12172 (Switch_View): A private subtype of a non-private type needs to be
12173 switched (the base type can have been switched without its private
12174 dependents because of the last branch of Check_Private_View.
12175 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
12177 (Instantiate_Type): Emit an error message whenever a class-wide type of
12178 a tagged incomplete type is used as a generic actual.
12179 (Find_Actual_Type): Extend routine to handle a component type in a child
12180 unit that is imported from a formal package in a parent.
12181 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
12182 agree on constrainedness, rather than checking against ultimate ancestor
12183 (Instantiate_Subprogram_Body): Create a cross-reference link to the
12184 generic body, for navigation purposes.
12186 2006-10-31 Robert Dewar <dewar@adacore.com>
12187 Thomas Quinot <quinot@adacore.com>
12189 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
12191 (New_Stream_Subprogram): When processing an attribute definition clause
12192 for a stream-oriented subprogram, record an entity node occurring at
12193 the point of clause to use for checking the visibility of the clause,
12194 as defined by 8.3(23) as amended by AI-195.
12195 (New_Stream_Subprogram): New procedure, factoring behaviour from both
12196 New_Stream_Function and New_Stream_Procedure.
12197 (New_Stream_Function, New_Stream_Procedure): Removed.
12198 (Analyze_Attribute_Definition_Clause, case Address): Check new
12199 Alignment_Check check
12201 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12202 Javier Miranda <miranda@adacore.com>
12203 Robert Dewar <dewar@adacore.com>
12205 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
12206 generate the same errors compiling under -gnatc.
12207 (Try_Object_Operation): If no candidate interpretation succeeds, but
12208 there is at least one primitive operation with the right name, report
12209 error in call rather than on a malformed selected component.
12210 (Analyze_Selected_Component): If the prefix is an incomplete type from
12211 a limited view, and the full view is available, use the full view to
12212 determine whether this is a prefixed call to a primitive operation.
12213 (Operator_Check): Verify that a candidate interpretation is a binary
12214 operation before checking the type of its second formal.
12215 (Analyze_Call): Add additional warnings for function call contexts not
12217 (Analyze_Allocator): Move the check for "initialization not allowed for
12218 limited types" after analyzing the expression. This is necessary,
12219 because OK_For_Limited_Init looks at the structure of the expression.
12220 Before analysis, we don't necessarily know what sort of expression it
12221 is. For example, we don't know whether F(X) is a function call or an
12222 indexed component; the former is legal in Ada 2005; the latter is not.
12223 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
12224 were missing. We also didn't handle qualified expressions. Now also
12225 allow function calls. Use new common routine OK_For_Limited_Init.
12226 (Analyze_Type_Conversion): Do not perform some legality checks in an
12227 instance, because the error message will be redundant or spurious.
12228 (Analyze_Overloaded_Selected_Component): Do not do style check when
12229 setting an entity, since we do not know it is the right entity yet.
12230 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
12231 (Analyze_Overloaded_Selected_Component): Same change
12232 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
12233 since regular incomplete subtypes are transformed into corresponding
12234 subtypes of their full views.

12236 as coming from source, for browsing purposes.
12237 (Try_Primitive_Operation): If formal is an access parameter, compare
12238 with base type of object to determine whether it is a primitive

12250 warn on infinite loops.
12251 Add \\ to some continuation messages
12252 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
12253 (Process_Bounds): If the bounds are integer literals that result from
12254 constant-folding, and they carry a user-defined type, preserve that type
12255 rather than treating this as an integer range.
12256 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
12257 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
12258 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
12259 left hand side of assignment.

12265 or AND THEN for possible tracking.
12266 (Analyze_Iteration_Scheme): Check for setting Current_Value for the

12270 Hristian Kirtchev <kirtchev@adacore.com>
12271 Bob Duff <duff@adacore.com>
12273 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
12274 procedure cannot be a protected operation (it is a basic_declaration,
12275 not a subprogram_declaration).
12276 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
12277 Subp. Add logic for entry processing.
12278 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.

12292 pass new parameters. Add support for adding the new extra access formal
12293 for functions whose calls are treated as build-in-place.
12294 (Analyze_A_Return_Statement): Correct casing in error message.
12295 Move Pop_Scope to after Analyze_Function_Return, because an extended
12296 return statement really is a full-fledged scope. Otherwise, visibility
12297 doesn't work right. Correct use of "\" for continuation messages.
12298 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
12299 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
12300 the node doesn't get properly marked as analyzed.
12301 (Analyze_Subprogram_Body): If subprogram is a function that returns
12302 an anonymous access type that denotes a task, build a Master Entity
12304 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
12305 proper usage of null exclusion in a result definition.
12306 (Process_Formals): Code cleanup and new error message.

12314 homonym chain if it corresponds with an abstract interface primitive.
12315 (Process_Formals): Replace membership test agains Incomplete_Kind with a
12316 call to the synthesized predicate Is_Incomplete_Type.

12319 (Analyze_Subprogram_Declaration): Check that abstract interface
12320 primitives are abstract or null.
12321 (Analyze_Subprogram_Specification): Remove previous check for abstract
12322 interfaces because it was not complete.
12323 (Has_Interface_Formals): Removed.

12328 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
12329 of Analyze_Package_Body, to create Itype references for anonymous
12330 access types created in the package declaration, whose designated types
12331 may have only a limited view.
12332 (Analyze_Package_Specification): For the private part of a nested
12333 package, install private_with_clauses of enclosing compilation unit if
12334 we are in its visible part.
12335 (Declare_Inherited_Private_Subprograms): Complete barrier
12336 to ensure that the primitive operation has an alias to some parent
12337 primitive. This is now required because, after the changes done for the
12338 implementation of abstract interfaces, the contents of the list of
12339 primitives has entities whose alias attribute references entities of
12340 such list of primitives.
12341 (Analyze_Package_Specification): Simplify code that handles parent units
12342 of instances and formal packages.
12343 (Uninstall_Declarations): Check the convention consistency among
12344 primitive overriding operations of a tagged record type.

12358 as potentially use-visible.
12359 (Find_Type): Handle the case of an attribute reference for
12360 implementation defined attribute Stub_Type (simply let the analysis of
12361 the attribute reference rewrite it).
12362 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
12363 type that appears in a Use_Type clause.
12364 (Analyze_Object_Renaming): Add support for renaming of the Priority
12366 (Find_Type): In Ada 2005, a task type can be used within its own body,
12367 when it appears in an access definition.
12368 (Analyze_Object_Renaming): Remove warning on null_exclusion.
12369 (Analyze_Object_Renaming): Introduce checks for required null exclusion
12370 in a formal object declaration or in a subtype declaration.
12371 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
12372 (Check_Null_Exclusion): New local routine to
12373 Analyze_Subprogram_Renaming. Check whether the formals and return
12374 profile of a renamed subprogram have required null exclusions when
12375 their counterparts of the renaming already impose them.
12376 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
12377 Determine whether an entity is inside a generic scope.
12378 (In_Open_Scope): First pass of documentation update.
12379 (Find_Expanded_Name): Add support for shadow entities associated with
12380 limited withed packages. This is required to handle nested packages.
12381 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
12382 that makes a renaming of a limited withed package illegal.

12385 Ed Schonberg <schonberg@adacore.com>
12387 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
12388 Check_Overriding_Indicator.
12389 (Analyze_Task_Definition): Ditto.
12390 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
12391 (Check_Overriding_Indicator): To find overridden interface operation,
12392 examine only homonyms that have an explicit subprogram declaration, not
12393 inherited operations created by an unrelated type derivation.
12394 (Check_Overriding_Indicator): When checking for the presence of "null"
12395 in a procedure, ensure that the queried node is a procedure

12398 type when the formal is an access to variable.
12399 (Analyze_Protected_Type): Add check for Preelaborable_Initialization

12409 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
12410 inherited from an interface ancestor by another interface in the
12411 context of an instance as 'late'.

12413 of a call to a function that dispatches on access result.
12414 (Check_Dispatching_Operation): In case of late overriding of a primitive
12415 that covers abstract interface subprograms we register it in all the
12416 secondary dispatch tables associated with abstract interfaces.
12417 (Check_Dispatching_Call): Add check that a dispatching call is not made
12418 to a function with a controlling result of a limited type. This is a
12419 current implementation restriction.
12420 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
12421 (Check_Dispatching_Operation): Do no emit a warning if the controlling
12422 argument is an interface type that is a generic formal.
12423 (Is_Interface_Subprogram): Removed.
12424 (Check_Dispatching_Operation): If the subprogram is not a dispatching
12425 operation, check the formals to handle the case in which it is
12426 associated with an abstract interface type.

12449 the context of generic instantiation.
12450 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
12451 abstract interface types; this is required to handle concurrent types

12468 qualification from an expression. There are numerous places where this
12469 ought to be used, but we currently only deal properly with zero or one
12471 (In_Instance); The analysis of the actuals in the instantiation of a
12472 child unit is not within an instantiation, even though the parent
12473 instance is on the scope stack.

12476 (Check_Obsolescent): Removed
12477 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

12495 (Has_Compatible_Alignment): New function
12496 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
12497 objects to handle the Ada 2005 case, where aliasedness no longer implies

12553 (Return_Object_Declarations): New field to support extended return
12555 (N_Extended_Return_Statement): New node for extended_return_statement
12557 (N_Return_Object_Declaration): New node for part of

12731 * a-rttiev.ads, a-rttiev.adb:
12732 This is a significant redesign primarily for the sake of automatic
12733 timer task termination but also to fix a design flaw.
12734 Therefore we are now using an RTS lock, instead of a protected
12735 object, to provide mutual exclusion to the queue of pending events
12736 and the type Timing_Event is no longer a protected type.

13240 abstract interface type, the static analysis is not enough to know if
13241 the interface is implemented or not by the source tagged type. Hence
13242 we must pass the work to the expander to generate the required code to
13243 evaluate the conversion at run-time.
13244 (Resolve_Equality_Op): Do not apply previous
13245 transformation if expansion is disasbled, to prevent anomalies when

13584 other basic tools. The full version that includes the Ada 2005 stuff

13911 positive. Also add checks against invalid values, and support for kb,
13912 mb. Ditto for -D switch.

13918 save/restore routines.
13919 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

13921 Since we are changing the tree format anyway, also get rid of the
13922 junk obsolete Immediate_Errors flag.
13923 (Tree_Read): Change the way of reading Tree_Version_String - now we

13959 * exp_ch2.adb: Update status of new Is_Known_Null flag
13961 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
13963 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in

14004 * sinfo.ads: Document that Mechanism_Code cannot be applied to
14005 renamed subprograms so that the front-end must replace the prefix

14014 (Freeze_Record_Type): Do not generate the tables associated with
14015 timed and conditional dispatching calls through synchronized
14016 interfaces if compiling under No_Dispatching_Calls restriction.
14017 When compiling for Ada 2005, for a nonabstract
14018 type with a null extension, call Make_Controlling_Function_Wrappers
14019 and insert the wrapper function declarations and bodies (the latter
14020 being appended as freeze actions).
14021 (Predefined_Primitive_Bodies): Do not generate the bodies of the
14022 predefined primitives associated with timed and conditional
14023 dispatching calls through synchronized interfaces if we are
14024 compiling under No_Dispatching_Calls.

14026 service is available before generating a call.
14027 (Make_Controlling_Function_Wrappers): New procedure.
14028 (Expand_N_Full_Type_Declaration): Create a class-wide master for

14030 tasks that implement such limited interface.
14031 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
14032 procedure spec and body of the Offset_To_Top function that is generated
14033 when the parent of a type with discriminants has secondary dispatch
14035 (Init_Secondary_Tags): Handle the case in which the parent of the type
14036 containing secondary dispatch tables has discriminants to generate the
14037 correct arguments to call Set_Offset_To_Top.
14038 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
14040 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
14041 Add Wide_[Wide_]Expanded_Name.
14042 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
14043 the same functionality of Get_Prim_Op_Address but applied to predefined
14044 primitive operations because the pointers to the predefined primitives
14045 are now saved in a separate table.
14046 (Parent_Size): Modified to get access to the separate table of primitive
14047 operations or the parent type.
14048 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
14049 functionality of Set_Prim_Op_Address but applied to predefined primitive
14051 (Set_Signature): New subprogram used to store the signature of a DT.
14052 (Displace): If the Offset_To_Top value is not static then call the
14053 function generated by the expander to get such value; otherwise use
14054 the value stored in the table of interfaces.
14055 (Offset_To_Top): The type of the actual has been changed to Address to
14056 give the correct support to tagged types with discriminants. In this
14057 case this value is stored just immediately after the tag field.
14058 (Set_Offset_To_Top): Two new formals have been added to indicate if the
14059 offset_to_top value is static and hence pass this value to the run-time
14060 to store it in the table of interfaces, or else if this value is dynamic
14061 and then pass to the run-time the address of a function that is
14062 generated by the expander to provide this value for each object of the
14065 * rtsfind.ads (Default_Prin_Op_Count): Removed.
14066 (Default_Prim_Op_Count): New entity

14075 Make_Adjust_Call done for a newly-allocated object.
14077 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
14078 in a subprogram are wrapped in a cleanup block, indicate that the
14079 subprogram contains an inner block with an exception handler.
14080 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
14081 Adjust call is for a newly-allocated object. In that case we must not
14082 assume that the finalization list chain pointers are correct (since they
14083 come from a bit-for-bit copy of the original object's pointers) so if
14084 the attach level would otherwise be zero (no change), we set it to 4
14085 instead to cause the pointers to be reset to null.
14087 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
14088 reset chain pointers to null.
14090 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14092 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
14093 string, and the context requires a loop for the assignment (e.g.
14094 because the left-hand side is packed), generate a unique name for the
14095 temporary that holds the string, to prevent spurious name clashes.

14099 Robert Dewar <dewar@adacore.com>
14100 Gary Dismukes <dismukes@adacore.com>
14102 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
14103 return unconstrained arrays.
14105 (Expand_Call): An indirect call through an access parameter of a
14106 protected operation is not a protected call.
14107 Add circuit to raise CE in Ada 2005 mode following call
14108 to Raise_Exception.
14109 (Register_DT_Entry): Do nothing if
14110 the run-time does not give support to abstract interfaces.
14111 (Freeze_Subprogram): In case of dispatching operations, do not generate
14112 code to register the operation in the dispatch table if the source
14113 is compiled with No_Dispatching_Calls.
14114 (Register_Predefined_DT_Entry): Generate code that calls the new
14115 run-time subprogram Set_Predefined_Prim_Op_Address instead of
14116 Set_Prim_Op_Address.
14118 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
14119 on array assignments if the right-hand side is a function call that has
14120 been inlined. Check is performed on the assignment in the block.
14121 (Process_Bounds): If bounds and range are overloaded, apply preference
14122 rule for root operations to disambiguate, and diagnose true ambiguity.
14123 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
14124 a tag-indeterminate right-hand side even when Expander_Active is True.
14125 Needed to ensure that dispatching calls to T'Input are allowed and
14126 get the tag of the target class-wide object.
14128 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
14129 an inherited primitive operation that already overrides several
14130 abstract interface primitives. For transitivity, the new entity must
14131 also override all the abstract interface primitives covered by the
14132 inherited overriden primitive.
14133 Emit warning if new entity differs from homograph in same scope only in
14134 that one has an access parameter and the other one has a parameter of
14135 a general access type with the same designated type, at the same
14136 position in the signature.
14137 (Make_Inequality_Operator): Use source locations of parameters and
14138 subtype marks from corresponding equality operator when creating the
14139 tree structure for the implicit declaration of "/=". This does not
14140 change anything in behaviour except that the decoration of the
14141 components of the subtree created for "/=" allows ASIS to get the
14142 string images of the corresponding identifiers.
14143 (Analyze_Return_Statement): Remove '!' in warning message.
14144 (Check_Statement_Sequence): Likewise.
14145 (Analyze_Subprogram_Body): For an access parameter whose designated type
14146 is an incomplete type imported through a limited_with clause, use the
14147 type of the corresponding formal in the body.
14148 (Check_Returns): Implicit return in No_Return procedure now raises
14149 Program_Error with a compile time warning, instead of beging illegal.
14150 (Has_Single_Return): Function returning unconstrained type cannot be
14151 inlined if expression in unique return statement is not an identifier.
14152 (Build_Body_To_Inline): It is possible to inline a function call that
14153 returns an unconstrained type if all return statements in the function
14154 return the same local variable. Subsidiary procedure Has_Single_Return
14155 verifies that the body conforms to this restriction.
14157 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
14158 same type, and one of them is of an anonymous access type, convert
14159 the other operand to it, so that this is a valid binary operation for
14161 (Resolve_Type_Conversion): Handle subtypes of protected types and
14162 task types when accessing to the corresponding record type.
14163 (Resolve_Allocator): Add '\' in 2-line warning message.
14164 Remove '!' in warning message.
14165 (Resolve_Call): Add '\' in 2-line warning message.
14166 (Valid_Conversion): Likewise.
14167 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
14168 resulting type may be an access type with an implicit dereference.
14169 Obtain the proper component from the designated type.
14170 (Make_Call_Into_Operator): Handle properly a call to predefined equality
14171 given by an expanded name with prefix Standard, when the operands are
14172 of an anonymous access type.
14173 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
14174 Explicit_Dereference and Resolve_Selected_Component, to verify that the
14175 prefix of the expression is not of an incomplete type. Allows full
14176 diagnoses of all semantic errors.
14177 (Resolve_Actuals): If the actual is an allocator whose directly
14178 designated type is a class-wide interface we build an anonymous
14179 access type to use it as the type of the allocator. Later, when
14180 the subprogram call is expanded, if the interface has a secondary
14181 dispatch table the expander will add a type conversion to force
14182 the displacement of the pointer.
14183 (Resolve_Call): If a function that returns an unconstrained type is
14184 marked Inlined_Always and inlined, the call will be inlined and does
14185 not require the creation of a transient scope.
14186 (Check_Direct_Boolean_Op): Removed
14187 (Resolve_Comparison_Op): Remove call to above
14188 (Resolve_Equality_Op): Remove call to above
14189 (Resolve_Logical_Op): Inline above, since this is only call.
14190 (Valid_Conversion): Handle properly conversions between arrays of
14191 convertible anonymous access types.
14194 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
14195 the literal in an unchecked conversion, because GCC 4.x needs a static
14196 value for a string bound.
14198 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14199 Hristian Kirtchev <kirtchev@adacore.com>
14201 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
14202 components of the corresponding record, take into account component
14203 definitions that are access definitions.
14204 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
14205 procedure is not considered a dispatching call and will be expanded
14208 2006-02-13 Javier Miranda <miranda@adacore.com>
14210 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
14211 controlling argument of the dispatching call is an abstract interface
14212 class-wide type then we use it directly.
14213 Check No_Dispatching_Calls restriction.
14214 (Default_Prim_Op_Position): Remove the code that looks for the last
14215 entity in the list of aliased subprograms. This code was wrong in
14217 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
14218 when the source is compiled with the No_Dispatching_Calls restriction.
14219 (Init_Predefined_Interface_Primitives): No need to inherit primitives
14220 if we are compiling with restriction No_Dispatching_Calls.
14221 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
14222 subprograms if we are compiling under No_Dispatching_Calls restriction.
14223 (Make_DT): Generate a dispatch table with a single dummy entry if
14224 we are compiling with the No_Dispatching_Calls restriction. In
14225 addition, in this case we don't generate code that calls to the
14226 following run-time subprograms: Set_Type_Kind, Inherit_DT.
14227 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
14228 of this subprogram if compiling with the No_Dispatching_Calls
14230 (Expand_Type_Conversion): Instead of using the actual parameter,
14231 the argument passed as parameter to the conversion function was
14232 erroneously referenced by the expander.
14233 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
14234 Set_Predefined_Primitive_Op_Address and Set_Signature.
14235 (Expand_Dispatching_Call): Generate call to
14236 Get_Predefined_Prim_Op_Address for predefined primitives.
14237 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
14238 predefined primitives.
14239 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
14240 primitives we reserve one dummy entry to ensure that the tag does not
14241 point to some memory that is associated with some other object. In
14242 addition, remove all the old code that generated the assignments
14243 associated with the signature of the dispatch table and replace them
14244 by a call to the new subprogram Set_Signature.
14245 (Set_All_DT_Position): Change the algorithm because now we have a
14246 separate dispatch table associated with predefined primitive operations.
14247 (Expand_Interface_Conversion): In case of non-static offset_to_top
14248 add explicit dereference to get access to the object after the call
14249 to displace the pointer to the object.
14250 (Expand_Interface_Thunk): Modify the generation of the actual used
14251 in the calls to the run-time function Offset_To_Top to fulfil its
14253 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
14255 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14257 * exp_dist.adb (Copy_Specification): For access parameters, copy
14258 Null_Exclusion flag, which will have been set for stream subprograms
14261 2006-02-13 Pascal Obry <obry@adacore.com>
14263 * expect.c (__gnat_expect_portable_execvp): New implementation. The
14264 previous implementation was using the C runtime spawnve routine but
14265 the corresponding wait was using directly the Win32 API. This was
14266 causing some times a lock when waiting for an event using
14267 WaitForSingleObject in __gnat_waitpid. This new implementation uses
14268 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
14269 API fixes this problem.
14271 2006-02-13 Robert Dewar <dewar@adacore.com>
14273 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

14281 array reference that is an explicit dereference, mark the converted
14282 (packed) array reference as analyzed to prevent a forthcoming
14283 reanalysis from resetting its type to the original (non-packed) array
14286 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14287 Javier Miranda <miranda@adacore.com>
14288 Eric Botcazou <ebotcazou@adacore.com>
14290 * exp_util.ads, exp_util.adb (Find_Prim_Op,
14291 Is_Predefined_Primitive_Operation): When
14292 searching for the predefined equality operator, verify that operands
14293 have the same type.
14294 (Is_Predefined_Dispatching_Operation): Remove the code that looks
14295 for the last entity in the list of aliased subprograms. This code
14296 was wrong in case of renamings.
14297 (Set_Renamed_Subprogram): New procedure
14298 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
14299 Exp_Type constant computed when entering this subprogram.

14301 (OK_To_Do_Constant_Replacement): New function
14302 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
14303 (Side_Effect_Free): An attribute reference 'Input is not free of
14304 side effect, unlike other attributes that are functions. (from code
14306 (Remove_Side_Effects): Expressions that involve packed arrays or records
14307 are copied at the point of reference, and therefore must be marked as
14308 renamings of objects.
14309 (Is_Predefined_Dispatching_Operation): Return false if the operation is
14310 not a dispatching operation.
14313 (Remove_Side_Effects): Lift enclosing type conversion nodes for
14314 elementary types in all cases.
14316 2006-02-13 Javier Miranda <miranda@adacore.com>
14318 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
14319 task types when accessing to the corresponding record type.
14320 Remove '!' in warning message.
14322 2006-02-13 Olivier Hainque <hainque@adacore.com>
14324 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
14325 to avoid useless and space inefficient overalignments on targets where
14326 Max_Alignment is larger than 16.
14328 2006-02-13 Pascal Obry <obry@adacore.com>
14330 * g-catiio.adb (Sec_Number): New type used to compute the number of
14331 seconds since 1-1-1970.
14332 (Image) [Natural]: The parameter was an Integer, as we can't deal with
14333 negative numbers (years, months...) it is better to have a Natural here.
14335 (Image) [Number]: Change parameter from Long_Integer to Number.
14336 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
14337 overflow for dates past year 2038.
14339 2006-02-13 Matthew Heaney <heaney@adacore.com>
14341 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
14344 2006-02-13 Arnaud Charlet <charlet@adacore.com>
14346 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
14348 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
14349 finalization can occur normally.
14351 2006-02-13 Vincent Celier <celier@adacore.com>
14353 * gnatcmd.adb (Rules_Switches): New table
14354 (Add_To_Rules_Switches): New procedure
14355 (GNATCmd): For command CHECK, put all options following "-rules" in the
14356 Rules_Switches table. Append these -rules switches after the -cargs
14359 2006-02-13 Robert Dewar <dewar@adacore.com>
14361 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
14362 These two cases were generating incorrect output, and if this unit
14363 was built with checks on, generated a discriminant mismatch constraint
14366 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14367 Robert Dewar <dewar@adacore.com>
14369 * lib-xref.adb (Get_Type_Reference): For a private type whose full
14370 view is an array type, indicate the component type as well, for
14371 navigation purposes.
14372 (Generate_Reference): Don't consider array ref on LHS to be a case
14373 of violating pragma Unreferenced.
14374 Do not give Ada 2005 warning except on real reference.
14376 2006-02-13 Vincent Celier <celier@adacore.com>
14378 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
14379 main source, add switch -mdebug-main=_ada_ so that the executable can
14380 be debugged by the standard VMS debugger.
14381 (Gnatmake): Set No_Main_Subprogram to True when there is no main
14382 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
14383 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
14384 of the last source, as the binding and linking phases are never
14386 Set all executable obsolete when rebuilding a library.
14388 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
14391 2006-02-13 Javier Miranda <miranda@adacore.com>
14394 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
14395 code to improve the error message reported when the program has
14396 declarations of abstract interface types and it is not compiled with
14397 the -gnat05 switch.
14398 (P_Access_Definition): Reorganize the code to improve the error
14399 message reported when the new Ada 2005 syntax for anonymous
14400 access types is used and the program is not compiled with the

14405 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,
14406 stylesw.ads, usage.adb, vms_data.ads: Implement -gnatyI switch
14409 2006-02-13 Javier Miranda <miranda@adacore.com>
14411 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser

14416 * prj.adb (Reset): Initialize the first element of table Namings with
14417 the standard naming data.
14419 2006-02-13 Vincent Celier <celier@adacore.com>
14421 * prj.ads (Error_Warning): New enumeration type
14423 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
14424 unknown, use the location of the project to report the error.
14425 (When_No_Sources): New global variable
14426 (Report_No_Ada_Sources): New procedure
14427 (Check): New parameter When_No_Sources. Set value of global variable

14438 Call Recursive_Check with parameter When_No_Sources.
14439 (Recursive_Check): New parameter When_No_Sources. Call itself and
14440 Prj.Nmsc.Check with parameter When_No_Sources.
14441 (Process): New parameter When_No_Sources. Call Check with parameter
14443 (Copy_Package_Declarations): New procedure to copy renamed parameters
14444 and setting the location of the declared attributes to the location
14445 of the renamed package.
14446 (Process_Declarative_Items): Call Copy_Package_Declarations for renamed
14449 2006-02-13 Vincent Celier <celier@adacore.com>
14451 * prj-makr.adb (Make): Preserve the comments from the original project
14453 When removing nodes (attributes Source_Dirs, Source_Files,
14454 Source_List_File and package Naming), save the comments and attach the
14455 saved comments to the newly created nodes.
14456 Do not add a with clause for the naming package if one already exists.

14464 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
14465 aliased entities to look for the overriden abstract interface
14467 (Is_Interface_Subprogram): Complete documentation.
14468 (Check_Dispatching_Operation): Do not generate code to register the
14469 operation in the dispatch table if the source is compiled with
14470 restriction No_Dispatching_Calls.
14471 (Override_Dispatching_Operation): Check for illegal attempt to override
14472 No_Return procedure with procedure that is not No_Return
14473 (Check_Dispatching_Call): Suppress the check for an abstract operation
14474 when the original node of an actual is a tag-indeterminate attribute
14475 call, since the attribute, which must be 'Input, can never be abstract.
14476 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
14477 call to the Input attribute (even when rewritten).
14478 (Propagate_Tag): Augment comment to indicate the possibility of a call
14479 to an Input attribute.
14481 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
14482 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
14484 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
14485 No_Wide_Characters is no longer partition-wide
14486 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
14489 2006-02-13 Douglas Rupp <rupp@adacore.com>
14491 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
14493 2006-02-13 Javier Miranda <miranda@adacore.com>
14495 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
14496 handles default-initialized components to keep separate the management
14497 of this feature but also avoid the unrequired resolution and
14498 expansion of components that do not have partially initialized
14500 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
14501 (Check_Bounds): Likewise.
14502 (Check_Length): Likewise.
14504 2006-02-13 Javier Miranda <miranda@adacore.com>
14505 Ed Schonberg <schonberg@adacore.com>
14507 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
14508 abstract interface type call analyze_and_resolve to expand the type
14509 conversion into the corresponding displacement of the
14510 reference to the base of the object.
14511 (Eval_Attribute, case Width): For systems where IEEE extended precision
14512 is supported, the maximum exponent occupies 4 decimal digits.
14513 (Accessibility_Message): Add '\' in 2-line warning message.
14514 (Resolve_Attribute): Likewise.
14515 (case Attribute_Access): Significantly revise checks
14516 for illegal access-to-subprogram Access attributes to properly enforce
14517 the rules of 3.10.2(32/2).
14518 Diagnose use of current instance with an illegal attribute.
14520 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
14522 (Enclosing_Generic_Unit): New function to return a node's innermost
14523 enclosing generic declaration node.
14524 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
14525 (Type_Access_Level): The accessibility level of anonymous acccess types
14526 associated with discriminants is that of the current instance of the
14527 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
14528 (Compile_Time_Constraint_Error): Handle case of conditional expression.
14529 (Kill_Current_Values_For_Entity): New function
14530 (Enter_Name): Change formal type to Entity_Id
14532 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
14533 Ed Schonberg <schonberg@adacore.com>
14534 Gary Dismukes <dismukes@adacore.com>
14536 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
14537 Analyze_Compilation_Unit.
14538 Detect and warn on redundant with clauses detected in a package spec
14539 and/or body when -gnatwr is used.
14540 (Analyze_Context): Analyze config pragmas before other items
14541 (Install_Context_Items): Don't analyze config pragmas here
14542 (Install_Limited_Withed_Unit): Set limited entity of package in
14543 with_clause so that cross-reference information or warning messages on
14544 unused packages can be properly generated
14545 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
14546 has Error_Posted set. Prevent infinite loops in illegal programs.
14547 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
14548 to the point of the error test requiring the current unit to be private.
14549 This ensures that private with clauses are not exempted from the basic
14550 checking for being a descendant of the same library unit parent as a
14551 withed private descendant unit.
14552 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
14553 handle private with clauses properly, as well as to account for cases
14554 where the withed unit is a public descendant of a private ancestor
14555 (in which case the current unit must be a descendant of the private
14556 ancestor's parent). The spec comments were updated accordingly. Also,
14557 the old error message in this subprogram was replaced with error
14558 messages that mirror the errors tested and reported by
14559 Check_Private_Child_Unit.
14560 Parameter and variable names improved for readability.
14561 (Install_Limited_Context_Clauses): Remove test for a withed unit being
14562 private as the precondition for calling
14563 Check_Private_Limited_Withed_Unit since that subprogram has been
14564 revised to test public units as well as private units.

14569 Javier Miranda <miranda@adacore.com>
14571 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
14572 that Scope_Stack.First = 1.
14573 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
14574 were not always properly handled previously.
14575 (Formal_Entity): Complete rewrite, to handle properly some complex case
14576 with multiple levels of parametrization by formal packages.
14577 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
14578 to the corresponding derived type declaration for proper semantics.
14580 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
14581 (Check_Component): Enforce restriction on components of
14582 unchecked_unions: a component in a variant cannot contain tasks or
14584 (Unchecked_Union): Allow nested variants and multiple discriminants, to
14586 Add pragma Ada_2005 (synonym for Ada_05)
14587 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
14588 were not always properly handled previously.
14589 Document that pragma Propagate_Exceptions has no effect
14590 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
14591 (Set_Convention_From_Pragma): Check that if a convention is
14592 specified for a dispatching operation, then it must be
14593 consistent with the existing convention for the operation.
14594 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
14595 longer required to specify an vtable-ptr component in the record. For
14596 compatibility reasons we leave the support for the previous definition.
14597 (Analyze_Pragma, case No_Return): Allow multiple arguments
14599 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
14600 non-overrideen inherited operation with a controlling result as
14601 illegal only its implicit declaration comes from the derived type
14602 declaration of its result's type.
14603 (Check_Possible_Deferred_Completion): Relocate the object definition
14604 node of the subtype indication of a deferred constant completion rather
14605 than directly analyzing it. The analysis of the generated subtype will
14606 correctly decorate the GNAT tree.
14607 (Record_Type_Declaration): Check whether this is a declaration for a
14608 limited derived record before analyzing components.
14609 (Analyze_Component_Declaration): Diagnose record types not explicitly
14610 declared limited when a component has a limited type.
14611 (Build_Derived_Record_Type): Code reorganization to check if some of
14612 the inherited subprograms of a tagged type cover interface primitives.
14613 This check was missing in case of a full-type associated with a private
14615 (Constant_Redeclaration): Check that the subtypes of the partial and the
14616 full view of a constrained deferred constant statically match.
14617 (Mentions_T): A reference to the current type in an anonymous access
14618 component declaration must be an entity name.
14619 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
14620 class_wide type to refer to full type, not to the incomplete one.
14621 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
14622 available. Required to give support to the certified run-time.
14623 (Analyze_Component_Declaration): In case of anonymous access components
14624 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
14625 (Process_Discriminants): For an access discriminant, use the
14626 discriminant specification as the associated_node_for_itype, to
14627 simplify accessibility checks.

14630 Javier Miranda <miranda@adacore.com>
14632 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
14633 abstract interpretations on an operator, remove interpretations that
14634 yield Address or a type derived from it, if one of the operands is an
14636 (Try_Object_Operation.Try_Primitive_Operation,
14637 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
14638 location when creating the new reference to a primitive or class-wide
14639 operation as a part of rewriting a subprogram call.
14640 (Try_Primitive_Operations): If context requires a function, collect all
14641 interpretations after the first match, because there may be primitive
14642 operations of the same type with the same profile and different return
14643 types. From code reading.
14644 (Try_Primitive_Operation): Use the node kind to choose the proper
14645 operation when a function and a procedure have the same parameter
14647 (Complete_Object_Operation): If formal is an access parameter and prefix
14648 is an object, rewrite as an Access reference, to match signature of
14649 primitive operation.
14650 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
14651 by an expanded name with prefix Standard, when the operands are of an
14652 anonymous access type.
14653 (Remove_Abstract_Operations): If the operation is abstract because it is
14654 inherited by a user-defined type derived from Address, remove it as
14655 well from the set of candidate interpretations of an overloaded node.
14656 (Analyze_Membership_Op): Membership test not applicable to cpp-class
14659 2006-02-13 Bob Duff <duff@adacore.com>
14661 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
14662 redundant use clauses.
14663 In particular, if the scope of two use clauses overlaps, but one is not
14664 entirely included in the other, we should not warn. This can happen
14665 with nested packages.
14666 (Analyze_Subprogram_Renaming): Protect the compiler against previously
14667 reported errors. The bug was reported when the compiler was built
14668 with assertions enabled.
14669 (Find_Type): If the node is a 'Class reference and the prefix is a
14670 synchronized type without a corresponding record, return the type
14673 2006-02-13 Javier Miranda <miranda@adacore.com>
14675 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
14676 if this is the full-declaration associated with a private declaration
14677 that implement interfaces, then the private type declaration must be
14679 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
14680 as aliased. The use of the 'access attribute is not available for such
14681 object (for this purpose the object should be explicitly marked as
14682 aliased, but being an anonymous type this is not possible).
14684 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14685 Robert Dewar <dewar@adacore.com>
14687 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
14688 compilation unit is an elaboration scope.
14689 (Add_Task_Proc): Add '\' in 2-line warning message.
14690 (Activate_All_Desirable): Deal with case of unit with'ed by parent
14692 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14693 Javier Miranda <miranda@adacore.com>
14695 * sem_type.adb (Write_Overloads): Improve display of candidate
14697 (Add_One_Interp): Do not add to the list of interpretations aliased
14698 entities corresponding with an abstract interface type that is an
14699 immediate ancestor of a tagged type; otherwise we have a dummy
14700 conflict between this entity and the aliased entity.
14701 (Disambiguate): The predefined equality on universal_access is not
14702 usable if there is a user-defined equality with the proper signature,
14703 declared in the same declarative part as the designated type.
14704 (Find_Unique_Type): The universal_access equality operator defined under
14705 AI-230 does not cover pool specific access types.
14706 (Covers): If one of the types is a generic actual subtype, check whether
14707 it matches the partial view of the other type.
14709 2006-02-13 Thomas Quinot <quinot@adacore.com>
14711 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
14712 line. This is necessary to allow In_Extended_Main_Unit to provide
14713 correct results for itypes while writing out expanded source.
14714 (Close_File): No need to update the source_index_table here since it's
14715 now done for each line.
14717 2006-02-13 Ed Schonberg <schonberg@adacore.com>
14718 Robert Dewar <dewar@adacore.com>
14720 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
14721 preserve the source unit where the itype is declared, and prevent a
14723 (Note_Implicit_Run_Time_Call): New procedure
14724 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
14727 * sprint.ads: Document use of $ for implicit run time routine call
14729 2006-02-13 Quentin Ochem <ochem@adacore.com>
14731 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
14734 2006-02-13 Bob Duff <duff@adacore.com>
14736 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
14737 Scan_Unsigned, so we do not scan leading blanks and sign twice.
14738 Integer'Value("- 5") and Integer'Value("-+5") now correctly
14739 raise Constraint_Error.
14741 * s-vallli.adb (Scan_Long_Long_Integer): Call
14742 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
14743 do not scan leading blanks and sign twice.
14744 Integer'Value("- 5") and Integer'Value("-+5") now correctly
14745 raise Constraint_Error.
14747 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
14748 Scan_Long_Long_Unsigned): Split out most of the processing from
14749 Scan_Long_Long_Unsigned out into
14750 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
14751 This prevents scanning leading blanks and sign twice.
14752 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
14755 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
14756 out most of the processing from Scan_Unsigned out into
14757 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
14758 This prevents scanning leading blanks and sign twice.
14760 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
14761 use with Modular'Value attribute.
14762 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
14765 2006-02-13 Robert Dewar <dewar@adacore.com>
14767 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

14960 * a-taster.ads, a-taster.adb: New files.
14962 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
14963 link to the version that does nothing. This way the task termination
14964 routine is not executed twice for the environment task when finishing
14965 because of an unhandled exception.
14967 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
14968 handler because of an unhandled exception.
14970 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
14971 System.Tasking.Utilities instead of that in System.Tasking.Stages.
14973 * s-finimp.adb (initialization code): Modify the soft link for the
14974 finalization of the global list instead of Adafinal.
14976 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
14977 non-tasking version of the soft link for task termination. We do
14978 nothing since if we are using the non-tasking version it
14979 means that the task termination functionality is not used.
14980 (Null_Finalize_Global_List): Add this null version for the procedure
14981 in charge of finalizing the global list for controlled objects.
14982 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
14983 instead for handling run-time termination in a more flexible way.
14984 (Adafinal_NT): This new procedure will take care of finalizing the
14985 global list for controlled objects if needed, but no tasking
14988 * s-tarest.adb (Task_Lock): Do not try to lock again the
14989 Global_Task_Lock if we already own it. Otherwise, we get blocked in
14990 some run-time operations.
14991 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
14992 until all nested locks have been released.
14993 (Task_Wrapper): Call the fall-back task termination handler. It
14994 applies to all tasks but the environment task.
14995 (Finalize_Global_Tasks): Add the call for the task termination
14996 procedure for the environment task.
14997 (Task_Wrapper): suppress warnings around declaration of
14998 Secondary_Stack_Address.
15000 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
15001 moved to the Common_ATCB record.
15002 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
15003 Common_ATCB record.
15004 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
15005 Common_ATCB record.
15007 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
15008 Fall_Back_Handler, and Specific_Handler.
15010 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
15011 defined in Ada.Task_Termination, to avoid circular dependencies.
15012 (Termination_Handler): Redefine this type here, alredy defined in
15013 Ada.Task_Termination, for avoiding circular dependencies.
15014 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
15015 for storing task termination handlers. In addition,
15016 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
15017 Common_ATCB because it is used by both the regular and the restricted
15019 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
15020 Common_ATCB because it is used by both the regular and the restricted
15022 (Common_ATCB): Added a dynamic task analyzer field.
15024 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
15025 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
15026 (Task_Wrapper): Call the task termination handler. It applies to all
15027 tasks but the environment task.
15028 (Finalize_Global_Tasks): Call the task termination procedure for the
15029 environment task. The call to Finalize_Global_List is now performed
15030 using the soft links mechanism.
15031 (Task_Wrapper): added dynamic stack analysis.
15033 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
15034 potentially blocking operations has been moved from
15035 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
15036 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
15037 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
15038 this run-time check.
15040 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
15041 of task termination procedure.
15042 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
15043 link for the task termination procedure.
15045 * bindusg.adb: (Bindusg): Added documentation for -u option.

15055 * opt.ads: Added flags used by dynamic stack measurement.
15056 (Max_Line_Length): Remove (not used anymore)
15058 * s-io.ads, s-io.adb (Standard_Error): new subprogram
15059 (Standart_Output): new subprogram
15060 (Set_Output): new subprogram
15061 (Put): now uses the value of Current_Out to know if the output has to be
15062 send to stderr or stdout.
15064 * s-stausa.ads: Complete implementation.
15066 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
15068 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
15069 list of Ada 05 files.
15070 (GNAT Library Units): Add AltiVec files.

15073 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
15074 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
15076 2005-12-09 Nicolas Setton <setton@adacore.com>

15079 file_name is empty.
15081 2005-12-09 Javier Miranda <miranda@adacore.com>
15082 Hristian Kirtchev <kirtchev@adacore.com>
15084 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
15085 to the specification because the frontend generates code that uses this
15087 (Set_Interface_Table): Add missing assertion.
15088 Update documentation describing the run-time structure.
15089 (Displace): New subprogram that displaces the pointer to the object
15090 to reference one of its secondary dispatch tables.
15091 (IW_Membership): Modified to use the new table of interfaces.
15092 (Inherit_TSD): Modified to use the new table of interfaces.
15093 (Register_Interface_Tag): Use the additional formal to fill the
15094 contents of the new table of interfaces.
15095 (Set_Interface_Table): New subprogram that stores in the TSD the
15096 pointer to the table of interfaces.

15110 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
15111 in all the calls to Expand_Interface_Thunk. Instead of referencing the
15112 record component containing the tag of the secondary dispatch table we
15113 have to use the Offset_To_Top run-time function to get this information;
15114 otherwise if the pointer to the base of the object has been displace
15115 we get a wrong value if we use the 'position attribute.
15117 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
15118 all the calls to Expand_Interface_Thunk.
15119 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

15122 ensure that the interfaces implemented by the ancestors are placed
15123 at the header of the generated list.
15124 (Expand_Interface_Conversion): Handle the case in which the displacement
15125 associated with the interface conversion is not statically known. In

15129 Get_Tagged_Kind and Set_Tagged_Kind.
15130 (Tagged_Kind): New function that determines the tagged kind of a type
15131 with respect to limitedness and concurrency and returns a reference to

15153 RE_TK_Tagged, RE_TK_Task.
15155 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
15156 Init_Secondary_Tags_Internal to allow its use with interface types and
15157 also to generate the code for the new additional actual required
15158 by Set_Offset_To_Top.
15159 (Build_Init_Statements): In case of components associated with abstract
15160 interface types there is no need to generate a call to its IP.
15161 (Freeze_Record_Type): Generate Select Specific Data tables only for
15163 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
15164 the bodies and specifications of the predefined primitive operations

15172 properly protected objects and attach handler in the case of the
15173 restricted profile.
15174 Move embeded package Select_Expansion_Utilities into a separate external
15176 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,

15186 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
15187 pointer initialization values. Make a SAVE_EXPR instead. Add comments
15188 about the use and expansion of SAVE_EXPRs in the various possible
15189 renaming handling cases.
15190 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
15191 abusing DECL_FCONTEXT.

15291 covered by the tag of the source.
15293 2005-12-09 Robert Dewar <dewar@adacore.com>
15295 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

15310 component associated with the secondary table of an abstract interface
15311 type, return the entity associated with such abstract interface type.
15312 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
15313 base type to create anonymous subtype, because entity may be a locally
15314 declared subtype or generic actual.
15315 (Find_Interface): New subprogram that given a tagged type and one of its
15316 component associated with the secondary table of an abstract interface
15317 type, return the entity associated with such abstract interface type.

15359 legal within a protected type that implements an interface.
15360 (Collect_Interfaces): Do not add to the list the interfaces that
15361 are implemented by the ancestors.
15362 (Derived_Type_Declaration): If the parent of the full-view is an
15363 interface perform a transformation of the tree to ensure that it has
15364 the same parent than the partial-view. This simplifies the job of the
15365 expander in order to generate the correct object layout, and it is
15366 needed because the list of interfaces of the full-view can be given in
15368 (Process_Full_View): The parent of the full-view does not need to be
15369 a descendant of the parent of the partial view if both parents are
15371 (Analyze_Private_Extension_Declaration): If declaration has an explicit
15372 "limited" the parent must be a limited type.

15386 (Process_Full_View): Improve the check for the "no hidden interface"
15387 rule as defined by AI-396.
15389 2005-12-09 Robert Dewar <dewar@adacore.com>
15391 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
15392 types, not on record subtypes.
15393 (Freeze_Entity): Code cleanup. Add barrier to the loop
15394 that generates the references for primitive operations. This allows to

15446 available user-specified stream attributes on limited parameters to
15447 also test the type directly rather than only its underlying type (for

15449 attributes are visible at the point of the subprogram declaration.
15450 For Ada 2005, the error message is modified to indicate that the

15483 types use the corresponding record type. This was not needed before
15484 the implementation of Ada 2005 synchronized types because
15485 concurrent types were never tagged types in Ada 95.

15614 files are not available at this point in a tool bootstrap. Newlib
15615 only has basic C library header files.
15617 2005-11-19 Richard Guenther <rguenther@suse.de>
15618 Roger Sayle <roger@eyesopen.com>
15621 * misc.c (internal_error_function): Don't use vsprintf to format

15633 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
15634 a temporary if taking the address of something that is neither
15635 reference, declaration, or constant, since the gimplifier
15636 can't handle that case.
15638 2005-11-17 Laurent Guerby <laurent@guerby.net>

15708 * gen-soccon.c: Complete value expansion should not be performed on
15709 TARGET, as it has the form of a math expression, and some components
15710 may be platform-defined macros.
15711 For VxWorks, generate the OK and ERROR values.
15712 New constants giving the sizes of the components of C struct timeval.

15718 * types.ads: Include All_Checks in Suppress_Array
15720 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as

15724 deal with different cases of static and dynamic elaboration checks (all
15725 checks does not count in the first case, but does in the second).

15731 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
15732 elementary types using the operator in standard. It is cleaner not to
15733 modify the programmers intent, especially in the case of floating-point.
15734 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
15735 it did not matter because we always rewrote a/=b to not(a=b).
15736 (Expand_Allocator_Expression): For an allocator expression whose nominal
15737 subtype is an unconstrained packed type, convert the expression to its
15738 actual constrained subtype.
15739 Implement warning for <= or >= where < or > not possible
15740 Fix to Vax_Float tests (too early in many routines, causing premature
15741 Vax_Float expansions.
15743 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
15744 to be used with packages and generic packages as well as with
15746 (Suppress): Set All_Checks, but not Elaboration_Check, for case
15747 of pragma Suppress (All_Checks)
15748 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
15749 a string literal for precise control over warnings.
15750 Avoid raise of pragma in case of unrecognized pragma and just return
15753 * sem_prag.ads: Minor reformatting
15755 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
15756 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

15759 Allow optional = after -gnatm
15760 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
15761 longer sets Elaboration_Checks.
15762 Code to set warning mode moved to Sem_Warn
15763 so that it can be shared by pragma processing.
15765 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
15768 * s-taprop-solaris.adb:
15769 Change some <= to =, to avoid new warning

15772 Fix obvious typo (Num_Tracebacks compared <= 0 instead of < 0)
15773 Fix obvious typo (Total_Errors_Detected <= 0 should be = 0)
15775 2005-11-14 Robert Dewar <dewar@adacore.com>
15777 * exp_vfpt.adb: Handle /= case
15778 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
15779 so that we do not get duplicate scaling for fixed point conversions.
15781 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
15783 2005-11-14 Matthew Gingell <gingell@adacore.com>
15785 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
15786 Increase default priority on Lynx from 15 to 17, and meet the Ada
15787 requirement that Default_Priority be ((Priority'First +
15788 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

15885 from a fat or thin pointer type and a constrained object type.
15886 (annotate_value): Handle BIT_AND_EXPR.
15887 (annotate_rep): Don't restrict the back annotation of inherited
15888 components to the type_annotate_only case.
15889 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
15890 we are not defining the type.
15891 <E_Record_Type>: Likewise.
15892 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
15893 to get advantage of the new maybe_stabilize_reference interface, to
15894 ensure that what we reference is indeed stabilized instead of relying
15895 on assumptions on what the stabilizer does.
15896 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
15897 type imported through a limited_with clause, use its non-limited view.
15898 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
15900 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
15901 of #if sections + explicit comparisons of convention identifiers.
15902 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
15903 before early-returning for certain types when code generation is
15905 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
15906 nullification of gnu_expr we do for objects with address clause and
15907 that we are not defining.
15908 (elaborate_expression_1): Do not create constants when creating
15909 variables needed by the debug info: the dwarf2 writer considers that
15910 CONST_DECLs is used only to represent enumeration constants, and emits
15912 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
15913 object with an address clause into an indirect reference, drop the
15914 initializing expression.
15916 (STACK_CHECK_BUILTIN): Delete.
15917 (STACK_CHECK_PROBE_INTERVAL): Likewise.

15924 related): For a prefix that is a dereference of a fat or thin pointer,
15925 if there is an actual subtype provided by the front-end, use that
15926 subtype to build an actual type with bounds template.
15927 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
15928 is provided by the front-end, use that subtype to compute the size of
15929 the deallocated object.
15930 (gnat_to_gnu): When adding a statement into an elaboration procedure,
15931 check for a potential violation of a No_Elaboration_Code restriction.
15932 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
15933 with extra arguments to control whether to recurse through non-values
15934 and to let the caller know if the stabilization has succeeded.
15935 (gnat_stabilize_reference): Now a simple wrapper around
15936 maybe_stabilize, for common uses without restriction on lvalues and
15937 without need to check for the success indication.
15938 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
15939 pass false instead of 0 as the FORCE argument which is a bool.
15940 (Identifier_to_gnu): Remove checks ensuring that an renamed object
15941 attached to a renaming pointer has been properly stabilized, as no such
15942 object is attached otherwise.
15943 (call_to_gnu): Invoke create_var_decl to create the temporary when the
15944 function uses the "target pointer" return mechanism.
15945 Reinstate conversion of the actual to the type of the formal
15946 parameter before any other specific treatment based on the passing
15947 mechanism. This turns out to be necessary in order for PLACEHOLDER
15948 substitution to work properly when the latter type is unconstrained.
15950 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
15952 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
15953 with extra arguments to control whether to recurse through non-values
15954 and to let the caller know if the stabilization has succeeded.
15956 * utils2.c (gnat_build_constructor): Only sort the fields for possible
15957 static output of record constructor if all the components are constant.
15958 (gnat_build_constructor): For a record type, sort the list of field
15959 initializers in increasing bit position order.
15960 Factor common code to build a storage type for an unconstrained object
15961 from a fat or thin pointer type and a constrained object type.
15962 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
15963 types variants, and process special cases of VIEW_CONVERT expressions
15964 as their NOP_EXPR counterpart to ensure we get to the
15965 CORRESPONDING_VARs associated with CONST_DECls.
15966 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
15967 on the right-hand side.

15972 are converting back to its original type.
15973 (convert) <JM input>: Fallthrough regular conversion code instead of
15974 extracting the object if converting to a type variant.
15975 (create_var_decl): When a variable has an initializer requiring code
15976 generation and we are at the top level, check for a potential violation
15977 of a No_Elaboration_Code restriction.
15978 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
15979 SIZE and SIZE_UNIT which we need for later back-annotations.
15980 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
15981 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
15982 is an unchecked union.
15983 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
15984 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
15985 main variant, just replace the VIEW_CONVERT_EXPR.

16121 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
16122 for task component, in the case of a limited aggregate. The enclosed
16123 object declaration will create it earlier. Otherwise, in the case of a
16124 nested aggregate, the object may appear in the wrong scope.
16125 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
16126 (Gen_Assign): If the component being assigned is an array type and the

16163 with an actual subtype so GIGI can make a correct size computation.
16164 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
16165 'Unrestricted_Access, if the designated type is an interface we
16166 add a type conversion to force the displacement of the pointer

16168 Use Universal_Real instead of Long_Long_Float when we need a high
16169 precision float type for the generated code (prevents gratuitous
16170 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
16171 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
16172 'Terminated for task interface class-wide objects. Generate a call to
16173 the predefined dispatching routine used to retrieve the _task_id from

16202 (Expand_N_Return_Statement): When returning a mutable record, convert
16203 the return value into its actual subtype in order to help the backend
16204 to return the actual size instead of the maximum. This is another
16205 aftermath of not returning mutable records on the sec-stack anymore.

16254 attribute of the N_Free_Statement.
16255 Generate itype for classwide designated object in both cases of
16256 user-specified storage pool: specific and class-wide, not only in the
16258 Raise CE when trying to set a not null access type object to null.

16523 addition, this test now only takes into account the progenitors.
16524 (Derive_Interface_Subprograms): No need to derive subprograms
16525 of ancestors that are interfaces.
16526 (Derive_Subprograms): Remove formal No_Predefined_Prims and the
16528 Change name Is_Package to Is_Package_Or_Generic_Package
16529 (Complete_Subprograms_Derivation): Handle the case in which the full
16530 view is a transitive derivation of the ancestor of the partial view.
16531 (Process_Full_View): Rename local subprogram Find_Interface_In_
16532 Descendant to Find_Ancestor_Interface to leave the code more clear.
16533 Remove wrong code that avoids the generation of an error message
16534 when the immediate ancestor of the partial view is an interface.
16535 In addition some minor reorganization of the code has been done to
16536 leave it more clear.
16537 (Analyze_Type_Declaration): If type has previous incomplete tagged
16538 partial view, inherit properly its primitive operations.
16539 (Collect_Interfaces): Make public, for analysis of formal
16541 (Analyze_Interface_Declaration): New procedure for use for regular and
16542 formal interface declarations.
16543 (Build_Derived_Record_Type): Add support for private types to the code
16544 that checks if a tagged type implements abstract interfaces.
16545 (Check_Aliased_Component_Type): The test applies in the spec of an
16547 (Access_Type_Declaration): Clean up declaration of malformed type
16548 declared as an access to its own classwide type, to prevent cascaded
16550 (Collect_Interfaces): For private extensions and for derived task types
16551 and derived protected types, the parent may be an interface that must
16552 be included in the interface list.
16553 (Access_Definition): If the designated type is an interface that may
16554 contain tasks, create Master_Id for it before analyzing the expression
16555 of the declaration, which may be an allocator.
16556 (Record_Type_Declaration): Set properly the interface kind, for use
16557 in allocators, the creation of master id's for task interfaces, etc.

16568 (Process_Formals): A non null qualifier on a non null named access
16569 type is not an error, and is a warning only if Redundant_Constructs

16573 Ed Schonberg <schonberg@adacore.com>
16575 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
16576 nested within Analyze_Package_Specification to install the private

16578 package instance of a generic child package.
16579 (Analyze_Package_Specification): When entering a private part of a
16580 package associated with a generic instance or formal package, the
16581 private declarations of the parent must be installed (by calling new
16582 procedure Install_Parent_Private_Declarations).
16583 Change name Is_Package to Is_Package_Or_Generic_Package
16584 (Preserve_Full_Attributes): For a synchronized type, the corresponding
16585 record is absent in a generic context, which does not indicate a

16590 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
16591 not try to rewrite a renamed stream attribute, because the operations
16592 on the type may not have been generated.
16593 Handle properly a renaming_as_body generated for a stream operation
16594 whose default is abstract because the object type itself is abstract.
16595 (Find_Type): If the type is incomplete and appears as the prefix of a
16596 'Class reference, it is tagged, and its list of primitive operations
16597 must be initialized properly.
16598 (Chain_Use_Clauses): When chaining the use clauses that appear in the
16599 private declaration of a parent unit, prior to compiling the private
16600 part of a child unit, find on the scope stack the proper parent entity
16601 on which to link the use clause.
16602 (Note_Redundant_Use): Emit a warning when a redundant use clause is
16604 (Analyze_Object_Renaming): An attribute reference is not a legal object
16605 if it is not a function call.

16623 entry renaming or a primitive of a limited interface.
16624 (Valid_Conversion): If the operand has a single interpretation do not
16625 remove address operations.
16626 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
16627 statement to inhibit warning.
16628 (Resolve_Unary_Op): Do not produce a warning when
16629 processing an expression of the form -(A mod B)
16630 Use Universal_Real instead of Long_Long_Float when we need a high
16631 precision float type for the generated code (prevents gratuitous
16632 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
16633 (Resolve_Concatenation_Arg): Improve error message when argument is an
16634 ambiguous call to a function that returns an array.
16635 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
16636 there is an implicit operator in the given scope if we are within an
16637 instance: legality check has been performed on the generic.
16638 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
16639 after resolving operand, to avoid false warnings on overloaded calls.

16646 a private type whose full view is a composite type.
16647 (Interface_Present_In_Ancestor): Protect the frontend against
16648 previously detected errors to ensure that its compilation
16649 with assertions enabled gives the same output that its
16650 compilation without assertions.

16652 Change name In_Actual to In_Generic_Actual (clean up)
16653 (Disambiguate): New predicate In_Actual, to recognize expressions that
16654 appear in the renaming declaration generated for generic actuals, and

17625 include the generation of dispatching subprograms when the type
17626 implements at least one interface.
17628 * lib.ads: Extend information in Load_Stack to include whether a given
17629 load comes from a Limited_With_Clause.
17631 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
17632 whether a potential circularity is harmless, because it includes units
17633 loaded through a limited_with clause. Extends previous treatment which
17634 did not handle properly arbitrary combinations of limited and
17635 non-limited clauses.
17637 2005-09-01 Nicolas Setton <setton@adacore.com>
17639 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
17640 to be encoded as typ___XBLU_lowerbound__upperbound instead of
17641 typ___XB_lowerbound__upperbound.
17643 2005-09-01 Thomas Quinot <quinot@adacore.com>
17645 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
17646 dummy access formal for RACW/RAS TypeCode TSS.
17647 (Build_TypeCode_Call): Do not generate dummy null access actual for
17648 calls to the TypeCode TSS.
17650 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17652 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
17653 fully qualified name, to distinguish instances with the same local name.
17655 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
17658 2005-09-01 Robert Dewar <dewar@adacore.com>

17666 (Free): New deallocation procedure for filter elements
17667 (Close): Deallocate any existing filter for the concerned connection
17669 2005-09-01 Laurent Pautet <pautet@adacore.com>
17671 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
17672 position set is provided, we compute one in order to reduce the maximum
17673 length of the keys. This computation first selects a character
17674 position between 1 and the minimum length of the keys in order to
17675 avoid reducing one of the keys to an empty string.
17676 (Initialize, Compute): When the ratio V to K is too low, the algorithm
17677 does not converge. The initialization procedure now comes with a
17678 maximum number of iterations such that when exceeded, an exception is
17679 raised in Compute. The user can initialize this ratio to another value
17681 Reformating and updated headers.
17683 2005-09-01 Javier Miranda <miranda@adacore.com>
17685 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
17686 that given an entity T creates and returns an Itype that duplicates the
17687 contents of T. The returned Itype has the null-exclusion
17688 attribute set to True, and its Etype attribute references T
17689 to keep the association between the two entities.
17690 Update copyright notice
17692 * sem_aggr.adb (Check_Can_Never_Be_Null,
17693 Aggregate_Constraint_Checks, Resolve_Aggregate,
17694 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
17696 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

17699 Robert Dewar <dewar@adacore.com>
17700 Hristian Kirtchev <kirtchev@adacore.com>
17702 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
17705 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
17707 Call Set_Result_Definition instead of Set_Subtype_Mark.
17708 (P_Subprogram_Specification): Add parsing of anonymous access result
17709 plus null exclusions. Call Set_Result_Definition instead of
17712 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
17713 (P_Access_Type_Definition): Add parsing for an anonymous access result
17714 subtype, plus parsing for null exclusions. Call Set_Result_Definition
17715 instead of Set_Subtype_Mark.
17717 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
17718 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
17719 (Result_Definition): New function for N_Function_Specifications.
17720 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
17721 N_Function_Specification.
17722 (Set_Null_Exclusion_Present): Allow this flag for
17723 N_Function_Specification.
17724 (Set_Result_Definition): New procedure for N_Function_Specifications.
17725 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
17726 and N_Function_Specification.
17728 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
17729 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
17730 Add support for LIMITED NEW for Ada 2005 AI-419
17731 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
17732 syntax for anonymous access results.
17733 Replace Subtype_Mark field by Result_Definition in
17734 N_Function_Specification and N_Access_Definition specs.
17735 Add Null_Exclusion_Present to spec of N_Function_Specification.
17736 (Result_Definition): New function for N_Function_Specification and
17737 N_Access_Function_Definition.
17738 (Set_Result_Definition): New procedure for N_Function_Specification and
17739 N_Access_Function_Definition.
17741 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
17742 Result_Definition for cases of N_Access_Function_Definition and
17743 N_Function_Specification.
17744 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
17746 2005-09-01 Vincent Celier <celier@adacore.com>
17748 * lib-writ.adb: Update Copyright notice
17749 (Write_With_Lines): On platforms where file names are case-insensitive,
17750 record the file names in lower case.
17751 (Write_ALI): For D lines, on platforms where file names are
17752 case-insensitive, record the file names in lower case.
17754 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17755 Emmanuel Briot <briot@adacore.com>
17757 * lib-xref.adb (Output_Overridden_Op): Display information on
17758 overridden operation.
17760 * lib-xref.ads: Add documentation on overridden operations.
17762 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
17765 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
17766 overriding entity information.
17768 2005-09-01 Vincent Celier <celier@adacore.com>
17770 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
17771 including those that are inherited.
17773 2005-09-01 Robert Dewar <dewar@adacore.com>
17775 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
17777 * par-prag.adb: Implement new pragma Debug_Policy
17779 * sem_prag.adb Implement new pragma Debug_Policy
17780 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
17781 Component_Size attribute specification. Give warning for ignored pragma
17784 * snames.h, snames.ads, snames.adb: Introduce entries in
17785 Preset_Names for Name_Disp_Asynchronous_Select,
17786 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
17787 Name_Disp_Timed_Select.
17788 New pragma Debug_Policy
17790 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
17792 Switch -gnata also sets Debug_Pragmas_Enabled
17794 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
17795 handle an explicit -gnata when compiling predefined files.
17797 2005-09-01 Vincent Celier <celier@adacore.com>
17799 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
17800 directories of projects that have no Ada sources.
17802 2005-09-01 Robert Dewar <dewar@adacore.com>
17804 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
17805 (makes a difference for wide characters)
17807 * widechar.adb, widechar.ads:
17808 Add Wide_Char_Byte_Count feature to count chars vs bytes
17810 2005-09-01 Thomas Quinot <quinot@adacore.com>
17811 Ed Schonberg <schonberg@adacore.com>
17812 Robert Dewar <dewar@adacore.com>
17814 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
17815 'Address attribute reference with an overloaded prefix, use the
17816 location of the prefix (not the location of the attribute reference) as
17817 the error location.
17818 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
17819 a function renaming thereof, is a valid prefix for 'Size (where it is
17820 intepreted as a function call).
17821 (Statically_Denotes_Entity): New predicate to determine whether the
17822 prefix of an array attribute can be considered static.
17825 (Eval_Attr): Fix failure to evaluate Component_Size for
17826 unconstrained arrays (resulted in wrong value in packed case, since
17827 back end cannot handle this case)
17829 2005-09-01 Robert Dewar <dewar@adacore.com>
17831 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
17832 error msgs for most common cases.
17833 Use new errout insertion char < (conditional warning)
17835 2005-09-01 Javier Miranda <miranda@adacore.com>
17836 Ed Schonberg <schonberg@adacore.com>
17838 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
17839 become local to the whole package.
17840 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
17841 the package was already analyzed the new algorithm "replaces" the
17842 real entities by the shadow ones. This is required to ensure that
17843 the order of these entities in the homonym chains does not change;
17844 otherwise we can have undefined references at linking time because
17845 in case of conflicts the external name of the entities will have
17846 a suffix that depends on the order of the entities in the chain.
17847 (Remove_Limited_With_Clause): Complementary code that completes the
17848 new algorithm and replaces the shadow entities by the real ones.
17849 (Install_Limited_Withed_Unit): When unchaining entities before the
17850 installation of the shadow entities, only regular entities of the
17851 public part must be taken into account. This is required to
17852 keep this routine in synch with the work done by Remove_Limited_
17854 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
17855 even if unit is analyzed, because the analysis of the unit is
17856 idempotent in any case, and the limited view of the unit may have to
17857 be installed for proper visibility.
17858 (Expand_Limited_With_Clause): Even if the unit in the implicit
17859 with_clause has been analyzed already, a limited view of the package
17860 must be built for the current context, if it does not exist yet.
17862 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17863 Javier Miranda <miranda@adacore.com>
17864 Gary Dismukes <dismukes@adacore.com>
17866 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
17867 defining entity for the instance body, make a new defining identifier
17868 rather than copying the entity of the spec, to prevent accidental
17869 sharing of the entity list.
17870 (Check_Private_View): When exchanging views of private types, build the
17871 list of exchanged views as a stack, to ensure that on exit the exchanges
17872 are undone in the proper order.
17873 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
17874 Restore the compilation environment in case of instantiation_error.
17875 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
17876 for an anonymous access result.
17877 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
17878 (Formal_Entity): Handle properly the case of a formal package that
17879 denotes a generic package renaming.
17881 2005-09-01 Thomas Quinot <quinot@adacore.com>
17883 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
17884 clause if the array aggregate is surrounded by parentheses.
17886 2005-09-01 Cyrille Comar <comar@adacore.com>
17887 Gary Dismukes <dismukes@adacore.com>
17888 Ed Schonberg <schonberg@adacore.com>
17889 Javier Miranda <miranda@adacore.com>
17891 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
17893 to check if a type is Constrained in cases related to code generation
17894 (rather than semantic checking) since otherwise we do not generate
17895 similar code for mutable private types depending if their
17896 discriminants are visible or not.
17897 (Check_Abstract_Overriding): Do not complain about failure to override
17898 the primitive operations used in dispatching selects since they will
17899 always be overriden at the freeze point of the type.
17900 (Access_Definition): Separate out handling for resetting the scope
17901 of an anonymous access function result type. Retrieve the scope
17902 of the associated function rather than using Current_Scope, which
17903 does not have a consistent value (depends on whether we're in the
17904 middle of analyzing formal parameters). Add ??? comment about
17905 finding a cleaner way to handle the special cases of scope setting.
17906 (Process_Incomplete_Dependents): A protected operation is never a
17907 dispatching operation (only its wrapper may be).
17908 (Build_Derived_Record_Type): In case of tagged private types that
17909 implement interfaces add derivation of predefined primitive
17911 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
17912 by two parameters that are used in case of derivation from abstract
17913 interface types: No_Predefined_Prims is used to avoid the derivation
17914 of predefined primitives from the interface, and Predefined
17915 Prims_Only is used to complete the derivation predefined primitives
17916 in case of private tagged types implementing interfaces.
17917 Fix typo in comments
17918 (Find_Interface_In_Descendant): Protect the frontend against
17919 wrong code with large circularity chains.
17920 (Is_Private_Overriding): Add support for entities overriding interface
17921 subprograms. The test failed because Entities associated with overriden
17922 interface subprograms are always marked as hidden (and used to build
17923 the secondary dispatch table); in this case the overriden entity is
17924 available through the field abstract_interface_alias (cf. override_
17925 dispatching_operation)
17926 (Access_Definition): Set the scope of the type to Current_Scope for the
17927 case of a function with an anonymous access result type.
17928 (Access_Subprogram_Declaration): Handle creation of the type entity for
17929 an access-to-function type with an anonymous access result.
17930 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
17931 in handling for N_Access_Function_Definition.
17932 (Analyze_Subtype_Declaration): Modify the text of error message.
17933 (Derived_Type_Declaration): Modify the text of error message.
17934 (Process_Subtype): Modify the text of error message plus cleanup
17935 of one redundant error message.
17936 (Analyze_Component_Declaration): Code cleanup.
17937 (Analyze_Object_Declaration): Code cleanup.
17938 (Analyze_Subtype_Declaration): Propagate the null-exclusion
17939 attribute in case of access types. Code cleanup.
17940 (Array_Type_Declaration): Code cleanup.
17941 (Process_Discriminants): Create the new null-excluding itype
17942 if required. Code cleanup.
17943 (Process_Subtype): Create the new null-excluding itype if
17944 required. Code cleanup.
17945 (Build_Derived_Record_Type): Code cleanup to avoid calling
17946 twice the subprogram derive_subprograms in case of private
17947 types that implement interfaces. In this particular case the
17948 subprogram Complete_Subprograms_Derivation already does the
17949 job associated with the second call.
17951 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
17952 conversion to the full view when generating an operation for a
17953 discriminant whose type may currently be private.
17955 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17956 Javier Miranda <miranda@adacore.com>
17958 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
17959 V (Obj.F), the rewriting does not involve the indexed component, but
17960 only the selected component itself.
17961 Do not apply the transformation if the analyzed node is an actual of a
17962 call to another subprogram.
17963 (Complete_Object_Operation): Retain the entity of the
17964 dispatching operation in the selector of the rewritten node. The
17965 entity will be used in the expansion of dispatching selects.
17966 (Analyze_One_Call): Improve location of the error message associated
17968 (Analyze_Selected_Component): No need to resolve prefix when it is a
17969 function call, resolution is done when parent node is resolved, as
17971 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
17972 when attempting to resolve a call transformed from its object notation.
17973 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
17974 of the argument list for each interpretation of the operation.
17975 (Try_Object_Operation): The designated type of an access parameter may
17976 be an incomplete type obtained through a limited_with clause, in which
17977 case the primitive operations of the type are retrieved from its full
17979 (Analyze_Call): If this is an indirect call, and the return type of the
17980 access_to_subprogram is incomplete, use its full view if available.
17982 2005-09-01 Javier Miranda <miranda@adacore.com>
17983 Gary Dismukes <dismukes@adacore.com>
17985 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
17986 access types the null-exclusion and access-to-constant attributes must
17988 (Analyze_Return_Statement): When the result type is an anonymous access
17989 type, apply a conversion of the return expression to the access type
17990 to ensure that appropriate accessibility checks are performed.
17991 (Analyze_Return_Type): For the case of an anonymous access result type,
17992 generate the Itype and set Is_Local_Anonymous_Access on the type.
17993 Add ??? placeholder for check to disallow returning a limited object
17994 in Ada 2005 unless it's an aggregate or a result of a function call.
17995 Change calls from Subtype_Mark to Result_Definition.
17996 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
17997 Result_Definition in call to Make_Function_Specification.
17998 (Build_Body_To_Inline): Change Set_Subtype_Mark to
17999 Set_Result_Definition.
18000 (Make_Inequality_Operator): Change formal Subtype_Mark to
18001 Result_Definition in call to Make_Function_Specification.
18002 (Process_Formals): Create the new null-excluding itype if required.
18003 (New_Overloaded_Entity): For an entity overriding an interface primitive
18004 check if the entity also covers other abstract subprograms in the same
18005 scope. This is required to handle the general case, that is, overriding
18006 other interface primitives and overriding abstract subprograms inherited
18007 from some abstract ancestor type.
18008 (New_Overloaded_Entity): For an overriding entity that comes from
18009 source, note the operation that it overrides.
18010 (Check_Conformance, Type_Conformant): Addition of one new formal
18011 to skip controlling formals in the analysis. This is used to
18012 handle overloading of abstract interfaces.
18013 (Base_Types_Match): Add missing case for types imported from
18014 limited-with clauses
18015 (New_Overloaded_Entity): Add barrier to protect the use of
18016 the "alias" attribute.
18018 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18020 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
18021 verify that the procedure and the entry are mode conformant.
18022 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
18023 as a different operator, which is often a cut-and-paste error.
18025 2005-09-01 Javier Miranda <miranda@adacore.com>
18026 Ed Schonberg <schonberg@adacore.com>
18028 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
18029 used in controlling parameters exclude null because it is necessary to
18030 read the tag to dispatch, and null has no tag.
18031 (Override_Dispatching_Operation): If the previous operation is inherited
18032 from an interface, it becomes hidden and does not participate in later
18035 2005-09-01 Javier Miranda <miranda@adacore.com>
18036 Ed Schonberg <schonberg@adacore.com>
18037 Gary Dismukes <dismukes@adacore.com>
18039 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
18040 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
18041 the expander will generate the corresponding run-time check to evaluate
18043 (Resolve_Call): Check for legal type of procedure name or prefix that
18044 appears as a trigger in a triggering alternative.
18045 (Valid_Conversion): If expression is ambiguous and the context involves
18046 an extension of System, remove System.Address interpretations.
18047 (Resolve_Qualified_Expression): Reject the case of a specific-type
18048 qualification applied to a class-wide argument. Enhance comment
18049 to explain checking of Original_Node.
18050 (Resolve_Type_Conversion): The location of the error message was not
18051 general enough to handle the general case and hence it has been removed.
18052 In addition, this patch improves the text of the message.
18053 (Resolve_Type_Conversion): Add missing support for access to interface
18055 (Resolve_Type_Conversion): If the target is a class-wide interface type,
18056 do not expand if the expression is the actual in a call, because proper
18057 expansion will take place when the call itself is expanded.
18058 (Resolve_Allocator): If the context is an unchecked conversion, the
18059 allocator inherits its storage pool, if any, from the target type of
18062 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18063 Javier Miranda <miranda@adacore.com>
18065 * sem_type.adb (Add_One_Interp): If a candidate operation is an
18066 inherited interface operation that has an implementation, use the
18067 implementation to avoid spurious ambiguities.
18068 (Interface_Present_In_Ancestor): In case of concurrent types we can't
18069 use the Corresponding_Record_Typ attribute to look for the interface
18070 because it is set by the expander (and hence it is not always
18071 available). For this reason we traverse the list of interfaces
18072 (available in the parent of the concurrent type).
18073 (Interface_Present_In_Ancestor): Handle entities from the limited view
18075 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18077 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
18078 from the list of required components.
18079 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
18080 primitive procedure of a limited interface with a controlling first
18082 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
18084 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
18085 capture if it is generated in the second operand of a short-circuit
18087 Do not capture values for variables with address clauses.
18088 (Is_Object_Reference): Treat a function call as an object reference only
18089 if its type is not Standard_Void_Type.
18091 2005-09-01 Ed Schonberg <schonberg@adacore.com>
18093 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied

18876 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
18877 longer protected objects. They have been replaced by lower-level
18878 suspension objects made up by a mutex and a condition variable (or
18879 their equivalent given a particular OS) plus some internal data to
18880 reflect the state of the suspension object.
18881 (Initialize, Finalize): Add this initialization procedure for
18882 Suspension_Object, which is a controlled type.

18911 until the state of the object is True. Program_Error is raised if
18912 another task is already waiting on that suspension object.
18913 (Initialize): Add this procedure for initializing the suspension
18914 object. It initializes the mutex and the condition variable which are
18915 used for synchronization and queuing, and it sets the internal state

19312 the generic that is created to represent the formal package.
19313 (Analyze_Package_Instantiation): Instantiate body immediately if the
19314 package is a predefined unit that contains inlined subprograms, and
19315 we are compiling for a Configurable_Run_Time.

19320 error message condition, null procedures are correctly detected now.
19321 (New_Overloaded_Entity): Bypass trivial overriding indicator check

19342 access to subprograms must be recursive.
19343 (Is_Unchecked_Conversion): Improve the test that recognizes
19344 instantiations of Unchecked_Conversion, and allows them in bodies that
19345 are to be inlined by the front-end. When the body comes from an

19366 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
19367 in the case where the target type is an anonymous access type of an
19368 object or component (that is, when Is_Local_Anonymous_Access is true).
19369 Prevent the special checks for conversions of access discriminants in
19370 the case where the discriminant belongs to a nonlimited type, since
19371 such discriminants have their accessibility level defined in the same
19372 way as a normal component of an anonymous access type.
19373 (Resolve_Allocator): When an allocator's designated type is a class-wide
19374 type, check that the accessibility level of type given in the
19375 allocator's expression or subtype indication is not statically deeper
19376 than the level of the allocator's access type.

19391 Call to obsolescent subprogram is now considered to be a violation of
19392 pragma Restrictions (No_Obsolescent_Features).
19393 (Check_Direct_Boolean_Operator): If the boolean operation has been
19394 constant-folded, there is nothing to check.
19395 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
19396 check on possible violation of restriction No_Direct_Boolean_Operators
19397 until after expansion of operands, to prevent spurious errors when

19433 both bound checks, rather than a conjunction.
19434 (Insert_Valid_Check): If the expression is an actual that is an indexed
19435 component of a bit-packed array, force expansion of the packed element
19436 reference, because it is specifically inhibited elsewhere.

20354 (check dos line terminator).
20355 (Check_Line_Max_Length): New procedure, split off from the existing
20356 Check_Line_Terminator routine. Separating this out allows -gnatyf to
20357 be properly recognized.
20359 * styleg.adb: Add ??? comment for line terminator reference
20361 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

20402 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
20403 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
20404 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
20405 analyzed if expansion is disabled (which could otherwise cause spurious
20406 error messages if expansion has been disabled due to previous
20407 (unrelated) errors).
20409 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
20410 is disabled, the entity denoted by the argument is the access type
20411 itself, not an underlying record type, so there is no need to go back
20412 to the Corresponding_Remote_Type.
20414 2005-03-29 Gary Dismukes <dismukes@adacore.com>
20415 Robert Dewar <dewar@adacore.com>
20417 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
20418 expand a call to an instance of
20419 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

20421 check is also generated, to ensure that the tag passed to the instance
20422 denotes a type in the class.
20423 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
20424 of Name_Generic_Dispatching_Constructor.
20426 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
20427 05 unit for AI-260-02).

20440 (Analyze_Subprogram_Renaming): Add special handling for
20441 the case of renaming of stream attributes when the renaming denotes a
20442 generic formal subprogram association for an abstract formal subprogram.
20443 Check that the attribute is a primitive stream attribute (and not
20444 a class-wide stream attribute) and then rewrite the attribute name
20445 as the name of the appropriate compiler-generated stream primitive.
20447 2005-03-29 Robert Dewar <dewar@adacore.com>
20449 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

20456 * freeze.adb (Freeze_Record_Type): If the type of the component is an
20457 itype whose parent is controlled and not yet frozen, do not create a
20458 freeze node for the itype if expansion is disabled.
20460 2005-03-29 Vincent Celier <celier@adacore.com>
20462 * make.adb (Gnatmake): Don't fail if the main project file is declared
20463 as having no Ada sources. Do not display message "no sources to
20464 compile" in quiet output.
20466 2005-03-29 Doug Rupp <rupp@adacore.com>
20468 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

20479 missing TYPE Improve the error message generated when compiling a
20480 limited interface in Ada83 or Ada95 mode.
20482 2005-03-29 Robert Dewar <dewar@adacore.com>
20484 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
20485 rather than proceed ahead using a junk attribute name.
20487 2005-03-29 Vincent Celier <celier@adacore.com>
20489 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
20491 * prj-part.adb (Parse_Single_Project): Set the location of a project
20492 on its defining identifier, rather than on the reserved word "project".
20494 * prj-proc.adb (Expression): Adapt to the fact that default of external
20495 references may be string expressions, not always literal strings.
20496 (Recursive_Process): Set Display_Name equal to Name
20497 when Location is No_Location, that is when there is no actual file.
20498 Get the Display_Name of the project from the source, when it is not a
20500 (Process): Use the Display_Name in error messages
20502 * prj-strt.adb (External_Reference): Allow default to be string
20503 expressions, not only literal strings.
20505 2005-03-29 Vincent Celier <celier@adacore.com>

20513 forbid conversion of a local access-to-subprogram type to a remote one.
20515 * sem_util.adb (Wrong_Type): For a record type that is the expanded
20516 equivalent type for a remote access-to-subprogram type, go back to the
20517 original RAS entity when displaying an error message, so the casing is
20518 the original source casing.

20522 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
20525 2005-03-29 Ed Schonberg <schonberg@adacore.com>
20527 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
20528 subtype if code is being pre-analyzed, to prevent un-expanded
20529 references to protected formals, among others.
20530 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
20531 interpretation that can be a call, include the result of the call as a
20532 possible interpretation of the dereference.
20534 * sem_ch5.adb (Process_Bounds): Determine type of range by
20535 pre-analyzing a copy of the original range, and then analyze the range
20536 with the expected type.
20538 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
20539 with an overloaded prefix where not all interpretations yield an
20540 access to subprogram, do not rewrite node as a call.
20541 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
20542 the node as a call once the context identifies the interpretation of
20543 the prefix whose call yields the context type.
20544 (Valid_Conversion): For the case of a conversion between
20545 local access-to-subprogram types, check subtype conformance using
20546 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
20547 detailed error message.
20549 2005-03-29 Ed Schonberg <schonberg@adacore.com>
20551 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
20552 indicator, indicate that the formal can never be null.
20553 (Process_Formals): If a formal has a non_null indicator, insert the
20554 resulting subtype immediately before the enclosing subprogram decl,
20555 and not at the beginning of the corresponding declarative part, to
20556 prevent access before elaboration (Ada2005).

20665 to install the visible declarations of the enclosing scope of a
20666 record_type_with_private to establish the proper visibility before
20667 freezing the entity and related subprograms.

20677 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
20678 into a new Check_Attr subprogram, in order to provide a more
20679 explanatory error message (including the name of the missing attribute).
20680 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
20681 subprogram determines whether a default implementation exists for a
20682 given stream attribute.
20683 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
20684 Determine whether to generate a default implementation for each stream
20685 attribute separately, as this depends on the specific attribute.
20687 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
20688 limited extension where a stream attribute is missing for a limited
20689 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

21217 derived type definition nodes.
21218 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
21219 (Task_Present, Set_Task_Present): New subprogram.
21220 (Task_Body_Procedure): Removed.
21221 (Set_Task_Body_Procedure): Removed.
21222 These subprogram have been removed because the attribute
21223 Task_Body_Procedure has been moved to the corresponding task type
21224 or task subtype entity to leave a field free to store the list
21225 of interfaces implemented by a task (for AI-345)
21226 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
21227 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
21228 expression flag Do_Range_Check
21229 (Exception_Junk): Change to Flag7 to accomodate above change
21230 (Box_Present, Default_Name, Specification, Set_Box_Present,
21231 Set_Default_Name, Set_Specification): Expand the expression
21232 "X in N_Formal_Subprogram_Declaration" into the corresponding
21233 two comparisons. Required to use the csinfo tool.

21236 "with string" given.
21238 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
21241 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
21244 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
21245 attribute Task_Body_Procedure rather than the old semantic field that
21246 was available in the task_type_declaration node.
21248 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
21249 interface type definitions.
21250 (P_Formal_Derived_Type_Definition): Modified to handle the list of
21253 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
21254 task type declaration.
21255 (P_Protected): Modified to handle the list of interfaces in a
21256 protected type declaration.
21258 2005-03-15 Doug Rupp <rupp@adacore.com>
21259 Vincent Celier <celier@adacore.com>
21261 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
21262 (Gen_Output_File_C): Likewise.
21263 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
21265 2005-03-15 Thomas Quinot <quinot@adacore.com>
21267 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
21268 is an N_Raise_Constraint_Error node, create a new copy of it without
21269 going through a call to Duplicate_Subexpr.
21271 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
21272 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

21274 Ed Schonberg <schonberg@adacore.com>
21280 * decl.c (gnat_to_gnu_field): Reject aliased components with a
21281 representation clause that prescribes a size not equal to the rounded
21282 size of their types.
21283 (gnat_to_gnu_entity, case E_Component): Always look at
21284 Original_Record_Component if Present and not the entity.

21288 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
21289 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
21290 expression to the type of the object when the object is constant.
21291 Reverse defer_debug_incomplete_list before traversing it, so that trees
21292 are processed in the order at which they were added to the list. This
21293 order is important when using the stabs debug format.
21294 If we are deferring the output of debug information, also defer this
21295 output for a function return type.
21296 When adding fields to a record, prevent emitting debug information
21297 for incomplete records, emit the information only when the record is
21299 (components_to_record): New parameter defer_debug.
21300 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
21301 (gnat_to_gnu_field_decl): New function.
21302 (substitution_list, annotate_rep): Call it.
21303 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
21304 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
21305 No longer update discriminants to not be a COMPONENT_REF.
21306 (copy_alias_set): Strip padding from input type; also handle
21307 unconstrained arrays properly.
21309 * gigi.h (write_record_type_debug_info): New function.
21310 Convert to use ANSI-style prototypes. Remove unused
21311 declarations for emit_stack_check, elab_all_gnat and
21312 set_second_error_entity.
21313 (gnat_to_gnu_field_decl): New decl.
21315 * utils.c (write_record_type_debug_info): New function.
21316 (finish_record_type): Delegate generation of debug information to

21318 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
21319 (update_pointer_to): Fix pasto.
21320 (convert) <UNION_TYPE>: Accept slight type variations when
21321 converting to an unchecked union type.
21323 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
21324 replace the N_Freeze_Entity with a null statement.
21326 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
21327 within a constrained subcomponent of an enclosing record, place the
21328 freeze nodes in the scope stack entry for the enclosing record.
21329 (Undelay_Type): New Subprogram.
21330 (Set_Small_Size): Pass T, the type to modify; all callers changed.
21331 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
21332 within records; allow them to have freeze nodes if their base types
21335 * exp_util.adb (Remove_Side_Effects): Properly test for
21336 Expansion_Delayed and handle case when it's inside an
21337 N_Qualified_Expression.
21339 * sem_ch3.adb (Derived_Type_Declaration): New predicate
21340 Comes_From_Generic, to recognize accurately that the parent type in a
21341 derived type declaration can be traced back to a formal type, because
21342 it is one or is derived from one, or because its completion is derived
21344 (Constrain_Component_Type): If component comes from source and has no
21345 explicit constraint, no need to constrain in in a subtype of the
21347 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
21348 Minor change to propagate Is_Ada_2005 flag
21350 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
21351 Expansion_Delayed is False.
21352 (assoc_to_constructor): Ignore fields that have a
21353 Corresponding_Discriminant.
21354 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
21355 function returns "by target", dereference the target pointer using the
21356 type of the actual return value.
21357 <all>: Be prepared for a null gnu_result.
21358 (processed_inline_subprograms): Check flag_really_no_inline
21359 instead of flag_no_inline.

21366 Ed Schonberg <schonberg@adacore.com>
21367 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
21369 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
21370 Must_Be_Byte_Aligned for cases where we do not need to use a
21371 System.Pack_nn unit.
21373 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
21375 Needed now that we do some processing for IN parameters as well. This
21376 may well fix some unrelated errors.
21377 (Expand_Call): Handle case of unaligned objects (in particular those
21378 that come from packed arrays).
21379 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
21380 renamed entity is an inherited operation, re-expand the call using the
21381 original operation, which is the one to call.
21382 Detect attempt to inline parameterless recursive subprogram.
21383 (Represented_As_Scalar): Fix to work properly with private types
21384 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
21385 accurate estimate. Yields True in far fewer cases than before,
21386 improving the quality of code that depends on this test.
21388 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
21389 over both visible and private declarations to remove them from tree,
21390 and mark subprograms declared in package as eliminated, to prevent
21391 spurious use in subsequent compilation of generic units in the context.
21393 * exp_util.ads: Minor cleanup in variable names
21395 * sem_eval.ads, sem_eval.adb: Minor reformatting
21396 (Compile_Time_Known_Bounds): New function
21398 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21400 * exp_ch7.adb (Convert_View): Use base types of underlying types when
21401 determining whether an unchecked conversion is needed for the argument
21402 of an initialization call.
21404 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21406 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
21407 that appears in the instantiation rather than the internal subtype
21408 generated in the wrapper package, to avoid anomalies in gigi when the
21409 target is derived from a private type whose full view is an access type.
21411 2005-03-15 Robert Dewar <dewar@adacore.com>
21413 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
21415 Add documentation to replace the use of this flag
21416 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
21419 2005-03-15 Thomas Quinot <quinot@adacore.com>
21421 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
21422 here from exp_attr so it can be shared between exp_attr and exp_dist.
21423 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
21424 all TSS names, not a subset thereof, and the previous name introduced
21425 an unnecessarily confusion that a distinction might exist between
21426 "OK" TSS names and some "not OK" TSS names.
21428 2005-03-15 Doug Rupp <rupp@adacore.com>
21430 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
21433 2005-03-15 Pascal Obry <obry@adacore.com>
21434 Eric Botcazou <ebotcazou@adacore.com>
21438 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
21439 when IN_RTS. This is to work around a bootstrap path problem.
21441 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
21442 table and pass it to __gnat_install_SEH_handler().
21443 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
21445 * lang.opt: Fix specification of -fRTS=.
21447 2005-03-15 Doug Rupp <rupp@adacore.com>

21449 Vincent Celier <celier@adacore.com>
21450 Arnaud Charlet <charlet@adacore.com>
21453 This change works fine when gnatlib is built from the gcc directory,
21454 but does not work when using the libada Makefile, since GCC_FOR_TARGET
21455 is not passed to ada/Makefile.in, so more work is needed by a
21456 Makefile/configure expert.
21458 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
21459 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
21460 Setup gnatlink switch -M for x86_64 linux, as it is already setup
21462 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
21463 Run ranlib on libgccprefix.a
21464 Define PREFIX_OBJS for Darwin, to build libgccprefix.
21465 (ADA_INCLUDE_SRCS): Split Ada packages.
21467 2005-03-15 Robert Dewar <dewar@adacore.com>
21469 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
21471 * impunit.adb: Add GNAT.UTF_32
21473 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
21475 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
21476 now uses GNAT.UTF_32).
21478 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
21479 capabilities for categorizing characters using Unicode categories
21481 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21483 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
21484 instantiation that has been rewritten as a package body, retrieve spec
21485 to generate proper name for implicit_with_clause.
21486 (Install_Parents): Recognize a parent that is an instantiation but has
21487 been rewritten as a package declaration during analysis.
21489 2005-03-15 Javier Miranda <miranda@adacore.com>
21490 Ed Schonberg <schonberg@adacore.com>
21492 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
21493 parameter reported some error we immediately return. This improves the
21494 behaviour of the frontend in case of errors.
21495 (Install_Parent, Remove_Parent): Introduce new flag
21496 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
21497 ancestor of a generic child unit, when the child is being instantiated.
21498 (Inline_Instance_Body): If we are compiling the private
21499 part or the body of a child unit, restore the proper visibility of the
21500 parents after compiling the instance body.
21502 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21503 Javier Miranda <miranda@adacore.com>
21506 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
21507 of a private type, in which case it is underlying_type that denotes
21508 the proper task. Also modified to use the new entity attribute
21509 that is directly available in the task type and task subtype entities
21510 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
21511 arrays when other dimensions than the first are constrained by
21512 discriminants of an enclosing record.
21513 (Insert_Explicit_Dereference): If the prefix is an indexed component or
21514 a combination of indexed and selected components, find ultimate entity
21515 and generate the appropriate reference for it, to suppress spurious
21517 (Note_Possible_Modification): If an entity name has no entity, return.
21518 (Is_Variable): A function call never denotes a variable.
21519 (Requires_Transient_Scope): For record types, recurse only on
21520 components, not on internal subtypes that may have been generated for
21521 constrained components.
21523 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21525 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
21526 Eliminated as candidates for resolution. Both efficient, and avoids
21527 anomalies with operators declared in deleted code.
21528 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
21529 expansion is disabled (as when compiling a generic) to prevent spurious
21530 warnings on prefixes of selected components.
21532 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21534 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
21535 attached to a list before checking whether it appears in the private
21536 declarations of the current package.
21537 (Make_Inequality_Operator): Insert declaration in proper declarative
21538 list rather than just setting the Parent field, so that
21539 Is_Private_Declaration can handle it properly.
21541 2005-03-15 Ed Schonberg <schonberg@adacore.com>
21543 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
21544 a renaming a body, check that the renamed subprogram in not intrinsic.
21545 (Find_Direct_Name): If several use_visible entities hide
21546 each other, and the context is a predefined file compiled through
21547 rtsfind, keep only the entity that comes from a predefined file.
21549 2005-03-15 Geert Bosch <bosch@adacore.com>
21551 * s-fatgen.adb (Valid): Extend special exceptions to account for long
21552 long float padding to also cover AMD64 and IA64.
21554 2005-03-15 Gary Dismukes <dismukes@adacore.com>
21556 * s-imgwch.adb: Add with and use of Interfaces.
21557 (Img_Wide_Character): Change type of Val to Unsigned_16.
21558 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
21560 2005-03-15 Matthew Gingell <gingell@adacore.com>

21568 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
21570 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95

21596 procedures in the bug boxes for various GNAT builds.
21598 2005-03-15 Vincent Celier <celier@adacore.com>

21606 Sergey Rybin <rybin@adacore.com>
21608 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
21609 too specific and long-winded to be appropriate for the GNAT User's
21611 Warn about use of GCC switches not documented in the GNAT User's Guide,
21612 as these may cause generated code to not conform to Ada semantics.
21613 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
21614 Add documentation for -gnat95 and -gnat05 switches
21615 Remove paragraph documenting obsolete way to refer to third party
21617 Add a few references to Ada_05 that were missing.
21618 Update documentation on -gnatZ/-gnatL.
21619 Document limitation when using -m64 under Solaris.
21620 Change the "Name Casing" subsection of the pretty-printer section

21663 we asked for an unknown mode.
21665 2005-02-12 Richard Henderson <rth@redhat.com>
21667 * utils.c (gnat_type_for_mode): Return NULL for COMPLEX modes;

22034 the formal subprogram.
22035 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,

22063 procedure", covering the case of a call to a formal abstract procedure
22064 that has statically tagged operands.

22066 a tag-indeterminate function call whose type is an ancestor of the

22167 handle other cases like RECORD_TYPE.
22169 * utils.c (gnat_pushdecl): Set TREE_NO_WARNING.
22171 2005-02-09 Ed Schonberg <schonberg@adacore.com>
22173 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
22174 component of an array of arrays in an assignment context, and the
22175 aggregate has component associations that require sliding on
22176 assignment, force reanalysis of the aggregate to generate a temporary
22177 before the assignment.
22178 (Must_Slide): Make global to the package, for use in Gen_Assign.
22180 2005-02-09 Ed Schonberg <schonberg@adacore.com>
22182 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
22183 unchecked union with no inferable discriminants, return a
22184 Raise_Program_Error node, rather than inserting it at the point the
22186 (Expand_Record_Equality, Component_Equality): Handle properly the case
22187 where some subcomponent is an unchecked union whose generated equality
22188 code raises program error.
22190 2005-02-09 Doug Rupp <rupp@adacore.com>
22192 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

22196 Arnaud Charlet <charlet@adacore.com>
22198 * init.c (__gnat_initialize): Add a new parameter eh which contains the
22199 address of the exception registration. The Win32 version of this
22200 routine calls __gnat_install_SEH_handler() to initialize the SEH
22201 (Structured Exception Handling) handler.
22202 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
22203 SEH (Structured Exception Handling) now.
22204 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
22205 (__gnat_initialize for ppc-vxworks): Adjust comments and the
22206 preprocessor condition protecting the call to the extra eh setup
22207 subprogram, which is only available for the ppc target.
22208 (__gnat_clear_exception_count): replaced reference to
22209 variable taskIdCurrent by call to taskIdSelf(), cleaner.
22211 * seh_init.c: New file.
22213 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
22214 (GNATBIND_OBJS): Idem.
22216 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
22217 routine takes a new parameter (a pointer to the exception registration
22218 for the SEH (Structured Exception Handling) support.
22220 * raise.h: (__gnat_install_SEH_handler): New prototype.
22221 Update copyright notice.
22223 * s-tassta.adb (Task_Wrapper): Declare the exception registration
22224 record and initialize it by calling __gnat_install_SEH_handler.
22226 2005-02-09 Vincent Celier <celier@adacore.com>
22228 * make.adb (Gnatmake): Do not fail when the main project has no object

22234 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
22235 [VMS]: Add translations for g-enblsp.adb.
22237 * s-asthan-vms.adb: Removed.
22238 * s-asthan-vms-alpha.adb: Added.
22240 2005-02-09 Pascal Obry <obry@adacore.com>
22242 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.

22245 2005-02-09 Arnaud Charlet <charlet@adacore.com>
22248 * Makefile.in: Link all gnat tools with -static-libgcc, since
22249 -shared-libgcc is now used by default on some systems (e.g. linux with
22251 Remove references to Makefile.prolog/generic, no longer used.
22253 2005-02-09 Vincent Celier <celier@adacore.com>
22255 * prj-makr.adb (Process_Directory): Put file name in canonical case
22256 before matching against the patterns.
22257 If gnatname has been invoked as <prefix>-gnatname
22258 then invoke the compiler as <prefix>-gcc, not just "gcc".
22260 2005-02-09 Ed Schonberg <schonberg@adacore.com>
22262 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
22263 with expansion disabled. The actual subtype is needed among other
22264 places when the selected component appears in the context of a loop
22265 bound, and denotes a packed array.
22266 (Operator_Check): Always use the first subtype in the
22267 error message, to avoid the appearance of internal base types.
22268 (Transform_Object_Operation): Copy each actual in full
22269 to the parameter associations of the constructed call, rather than
22270 using the shallow copy mechanism of New_Copy_List. This ensures that
22271 the chaining of named associations is done properly.
22272 (Complete_Object_Operation): Rewrite node, rather than
22273 replacing it, so that we can trace back to the original selected
22276 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
22277 and calls that use object notation, if the called function is not
22278 declared in a withed unit, place the elaboration constraint on the
22279 unit in the context that makes the function accessible.
22280 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
22281 imposes an elaboration constraint between two packages.
22283 2005-02-09 Ed Schonberg <schonberg@adacore.com>
22285 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
22286 views of a private type after handling its private dependents, to
22287 maintain proper stack discipline between entry and exit from the
22290 2005-02-09 Cyrille Comar <comar@adacore.com>
22292 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

22297 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
22298 fields for foreign threads.

22303 recursion warnings when compiled with -gnatdm.
22305 2005-02-09 Robert Dewar <dewar@adacore.com>
22307 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
22308 Slight fix to documentation of -gnaty with no parameters
22310 * xr_tabls.ads: Add ??? comment for missing overall comment
22312 * xsinfo.adb: Make default file name be sinfo.h, since this is what
22313 we now use by default.
22315 * xsnames.adb: Adjust end of file test to look for five space followed
22316 by '#' instead of six spaces. The format of xsnames.adb was modified
22317 in the last update.
22319 * a-numeri.ads: Add reference to AI-388 for greek letter pi
22322 * clean.adb: Minor reformatting.
22324 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
22325 gnatname.adb: Minor reformatting
22326 Add 2005 to copyright output when utility is run
22328 * csets.adb: Eliminate obsolete comment
22330 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
22333 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
22335 2005-02-09 Sergey Rybin <rybin@adacore.com>
22337 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
22338 the difference between compact and incompact layout and add the record
22339 representation clause to the example illustrating different layouts.
22340 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
22341 component clauses").
22343 2005-02-09 Florian Villoing <villoing@adacore.com>
22345 * gnat_ugn.texi: Fix typos.
22346 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
22348 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
22349 in the generated documentation.
22351 2005-02-09 Arnaud Charlet <charlet@adacore.com>
22353 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

22393 * exp_util.ads: Minor correction in comment.
22395 2005-02-09 Arnaud Charlet <charlet@adacore.com>
22397 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
22398 since this procedure is now too complex to be worth inlining.

22402 * utils.c (gnat_define_builtin): Remove.
22403 (gnat_install_builtins): Use build_common_builtin_nodes.

22651 The current code actually does not check antyhing - this a placeholder
22652 for future refinements.

22697 variable Dynamic_Async.
22698 (Build_Subprogram_Receiving_Stubs): Make PCS-specific

23076 access value, if appropriate.
23078 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
23079 emitting 'assigned but never read' warning on a variable on the basis

23153 when an accept statement has a pragma Unreferenced for it.
23155 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
23156 and the Has_Pragma_Unreferenced flag for each formal before analyzing
23157 the body, to ensure that warnings are properly emitted for each accept
23158 statement of a given task entry.
23160 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
23162 * Makefile.in: Add support for foreign threads on VMS.

23180 (Remove_Next_Debug): Same fix
23182 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
23183 maintain back pointers now, though we did not used to, and comments
23185 (Prepend): Remove pragma Inline.
23186 (Remove_Next): Same cleanup
23188 2004-12-07 Thomas Quinot <quinot@adacore.com>
23190 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
23191 used to record an implicit dereference as a read operation on its
23192 prefix when operating under -gnatc. Necessary to avoid spurious
23193 'variable assigned but never read' warnings in that mode.
23194 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
23195 is a non-overloaded implicit dereference, call the above subprogram to
23196 ensure proper recording of references.
23198 2004-12-07 Gary Dismukes <dismukes@adacore.com>
23200 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
23201 to be resolved later as part of Analyze_Iteration_Scheme's call to
23204 2004-12-07 Ed Schonberg <schonberg@adacore.com>
23206 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

23239 Sergey Rybin <rybin@adacore.com>
23241 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
23242 Files" with the new tool and package names.
23243 Reformatting to suppress most of the warnings for line too long
23244 Document the new section "Project Search Path:" in the output of
23246 Add gnatmetric section
23248 2004-12-07 Vincent Celier <celier@adacore.com>
23250 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
23251 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
23252 and -eit to -ept. Added qualifier
23253 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
23255 2004-11-27 Andreas Schwab <schwab@suse.de>
23257 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
23259 2004-11-25 Arnaud Charlet <charlet@adacore.com>
23261 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
23262 internal implementation unit GNAT.Sockets.Thin,
23263 as their usage for sockets is non-portable (using the read and write
23264 functions from the system runtime library is fine on UNIX but won't
23265 work under Windows).
23267 * mingw32.h: Update copyright notice.
23269 2004-11-25 Arnaud Charlet <charlet@adacore.com>
23271 * ada-tree.h: Minor reformatting of previous change to avoid lines
23272 longer than 79 characters.

23293 Style_Check_Order_Subprograms.
23295 2004-11-18 Arnaud Charlet <charlet@adacore.com>
23297 * adaint.h, adaint.c
23298 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
23300 Add also a cast to kill another warning.
23301 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
23302 parameter with the priority class of the parent process instead of
23303 always using the NORMAL_PRIORITY_CLASS.
23304 (__gnat_dup): New function.
23305 (__gnat_dup2): New function.
23306 (__gnat_is_symbolic_link): Enable the effective body of this
23307 function when __APPLE__ is defined.
23309 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
23312 2004-11-18 Olivier Hainque <hainque@adacore.com>
23314 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
23315 address of which may be used to represent "others" and "all others"
23316 choices in exception tables, instead of the current harcoded
23317 (void *)0 and (void *)1.
23318 (Setup_Exception): Do nothing in the GNAT SJLJ case.
23320 * gigi.h (others_decl, all_others_decl): New decls representing the
23321 new Others_Value and All_Others_Value objects.
23322 (struct attrib): Rename "arg" component as "args", since GCC expects a
23323 list of arguments in there.
23325 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
23326 corresponding objects exported by a-exexpr, instead of hardcoded dummy
23329 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
23330 others_decl and all_others_decl instead of hardcoded dummy addresses
23331 to represent "others" and "all others" choices, which is cleaner and
23332 more flexible with respect to the possible eh pointer encoding policies.
23334 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
23335 (process_attributes): Account for the naming change of the "args"
23336 attribute list entry component.
23338 * decl.c (build_attr_list): Rename into prepend_attributes to allow
23339 cumulating attributes for different entities into a single list.
23340 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
23341 attributes for the current entity and propagate first subtype
23342 attributes to other subtypes.
23343 <E_Procedure>: Attribute arguments are attr->args and not
23344 attr->arg any more.
23345 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
23346 argument provided, as this is what GCC expects. Use NULL_TREE instead
23349 2004-11-18 Robert Dewar <dewar@adacore.com>
23351 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
23352 Minor reformatting througout (including new function specs)
23353 Add ??? comments asking for clarification.
23355 2004-11-18 Thomas Quinot <quinot@adacore.com>
23357 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
23358 incomplete duplicate implementation of this subprogram from butil.
23360 2004-11-18 Thomas Quinot <quinot@adacore.com>

23363 procedures factors the common processing for building an RPC receiver
23364 for an RCI package or an RACW type.
23365 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
23366 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
23367 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
23369 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
23371 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
23373 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
23374 distribution subprogram identifiers that are either subprogram numbers

23377 string distribution identifiers assigned to a given subprogram.
23378 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
23379 (Add_RAS_Dereference_TSS): Add comments.
23380 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
23381 is not referenced yet because it will be used by the PolyORB DSA
23383 (Insert_Partition_Check): Remove fossile code.
23384 (First_RCI_Subprogram_Id): Document this constant.
23385 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
23387 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
23388 replaced with calls to Get_Library_Unit_Name_String. Previously there
23389 were several instances of the same code in different locations in the
23390 compiler; this checkin completes the replacement of all of these
23391 instances with calls to a common subprogram.
23392 Minor reformatting.
23394 * sem_dist.adb: Remove comment noting that RPC receiver generation
23395 should be disabled for RACWs that implement RASs.
23396 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

23400 qualified name of a library unit into the name buffer.
23401 (Note_Possible_Modification): Generate a reference only
23402 if the context comes from source.
23404 * snames.ads (PCS_Names): New subtype corresponding to names of
23405 supported implementations of the Partition Communication Subsystem
23406 (PCS) (i.e. the runtime library support modules for the distributed

23420 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
23421 (Expand_Pragma_Psect_Object): New procedure
23422 These procedures contain the revised and cleaned up processing for
23423 these two pragmas. This processing was formerly in Sem_Prag, but
23424 is more appropriately moved here. The cleanup involves making sure
23425 that the pragmas are properly attached to the tree, and that no
23426 nodes are improperly shared.
23428 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
23429 pragmas to Exp_Prag, which is more appropriate.
23430 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
23431 check for duplicates Remove use of Is_Psected flag, no longer needed.
23432 Use new Make_String_Literal function with string.
23434 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
23435 that are functions return universal values, that have to be converted
23436 to the context type.
23437 Use new Make_String_Literal function with string.
23438 (Get_Stream_Convert_Pragma): New function, replaces the use of
23439 Get_Rep_Pragma, which had to be kludged to work in this case.
23441 * freeze.adb: Use new Has_Rep_Pragma function
23443 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
23444 function with string.
23445 Use new Has_Rep_Pragma function.
23447 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
23450 2004-11-18 Robert Dewar <dewar@adacore.com>
23452 * errout.ads, errout.adb: (First_Sloc): New function
23454 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
23455 check (-gnatyx) instead of being included as a redundant construct
23458 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
23459 Style_Check_Order_Subprograms.
23461 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
23462 stylesw.adb: Add Style_Check_Xtra_Parens
23464 * usage.adb: Add line for -gnatyx (check extra parens)
23466 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
23468 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23469 Robert Dewar <dewar@adacore.com>
23471 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
23472 discriminant of a constrained subtype, analyze the copy of the
23473 corresponding constraint, because in some cases it may be only
23474 partially analyzed.
23475 Removes long-lived ??? comments.
23477 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
23478 handled controlled or secondary-stack expressions within the
23479 iteration_scheme of a loop.
23481 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
23482 bounds that may contain functions calls, to prevent memory leaks when
23483 the bound contains a call to a function that uses the secondary stack.
23484 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
23485 generate temporaries for loop bounds that might contain function calls
23486 that require secondary stack and/or finalization actions.
23488 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
23489 selected component and the selector is overloadable (not just a
23490 function) treat as function call, Analyze_Call will disambiguate if
23492 (Analyze_Selected_Component): Do not generate an actual subtype for the
23493 selected component if expansion is disabled. The actual subtype is only
23494 needed for constraint checks.
23495 (Analyze_Allocator): If restriction No_Streams is set, then do
23496 not permit objects to be declared of a stream type, or of a
23497 composite type containing a stream.
23499 * restrict.ads: Remove the a-stream entry from Unit_Array, since
23500 No_Streams no longer prohibits with'ing this package.
23502 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
23503 discriminants, but the parent base has unknown discriminants, there is
23504 no discriminant constraint to inherit. Such a discrepancy can arise
23505 when the actual for a formal type with unknown discriminants is a
23506 similar private type whose full view has discriminants.
23507 (Analyze_Object_Declaration): If restriction No_Streams is set, then
23508 do not permit objects to be declared of a stream type, or of a
23509 composite type containing a stream.
23511 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23513 * exp_dbug.ads: Update documentation to reflect simpler encoding for
23514 protected operations.
23516 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
23517 generated name, it complicates decoding in gdb and hinders debugging
23518 of protected operations.
23519 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
23520 flag for the protected entry barrier function.
23521 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
23522 flag for the protected entry function.

23528 * Makefile.in: Inform the value of the variable GMEM_LIB in the
23529 Darwin-specific section.
23531 * lang-specs.h: Change the placement of the %1 marker.
23532 Works around the fact that gcc adds -fPIC by default under Darwin.
23534 2004-11-18 Ed Schonberg <schonberg@adacore.com>
23536 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
23537 type of the object with the packed array type, set the Analyzed flag
23538 on the object if it is an entity or simple indexed component, to avoid
23539 spurious type errors.
23541 2004-11-18 Gary Dismukes <dismukes@adacore.com>
23543 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
23544 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
23545 separate line from the version message.
23547 2004-11-18 Ed Falis <falis@adacore.com>
23549 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
23551 (init_float): Eliminate initialization of floating point status for
23552 AE653. The instructions have no effect for vThreads.
23554 2004-11-18 Vincent Celier <celier@adacore.com>
23556 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
23557 gnatbind is invoked with -shared.
23559 2004-11-18 Jose Ruiz <ruiz@adacore.com>
23561 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
23562 for Detect_Blocking which is redundant with the check done within the
23563 procedure Protected_Single_Entry_Call.
23564 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
23565 Detect_Blocking which is redundant with the check done within the
23566 procedure Protected_Single_Entry_Call.
23568 2004-11-18 Vincent Celier <celier@adacore.com>
23570 * makegpr.adb (Compile): Put the compiling switches (in package
23571 Compiler and on the command line) immediately after "-c", instead of
23572 at the end of the command line invocation of the compiler, when
23573 compiling a non-Ada file.
23574 (Build_Global_Archive): When there is no need to rebuild the archive,
23575 set Global_Archive_Exists, so that the archive is passed to the linker
23578 2004-11-18 Robert Dewar <dewar@adacore.com>
23579 Sergey Rybin <rybin@adacore.com>
23582 Remove extra paren check from list of checks for redundant constructs
23583 Add documentation of new -gnatyx style check (check extra parens)
23584 Remove paragraph about gnatelim debug options.
23586 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
23587 objects rather than forbidding dependencies on the package Ada.Streams.
23589 * sinfo.ads: Add ??? note that we should document pragmas passed to
23592 * g-expect.ads: Fix a few typos in the comments.
23594 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
23596 * misc.c (gnat_handle_option): Use %< and %> for quoting in
23599 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
23601 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
23603 2004-11-07 Andreas Schwab <schwab@suse.de>
23605 * Makefile.in (install-gnatlib): Remove spurious hyphen.
23607 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
23610 * Makefile.in (darwin): Set soext to .dylib.
23612 2004-10-26 Vincent Celier <celier@gnat.com>
23613 Thomas Quinot <quinot@act-europe.fr>
23615 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
23616 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
23617 there is no use of GNAT.Sockets.Constants.
23618 Remove remaining pragma Import for C_Write
23619 Remove C_Read and C_Write from internal implementation unit
23620 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
23621 the read and write functions from the system runtime library is fine
23622 on UNIX but won't work under Windows).
23624 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
23625 (Check_Selector): Use C_Recv instead of C_Read.
23626 Selectors are the GNAT.Sockets abstraction to perform a select()
23627 call on a set of descriptors. To allow abortion of an ongoing
23628 select operation, some data is written to a dedicated socket that
23629 is always monitored.
23630 Under Windows, the write and read library functions cannot operate
23631 on sockets, so we need to use send and recv instead, which is portable
23632 across all supported platforms.
23634 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
23635 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
23636 (using the read and write functions from the system runtime library is
23637 fine on UNIX but won't work under Windows).
23639 2004-10-26 Nicolas Setton <setton@act-europe.fr>

23645 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
23646 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
23649 * Makefile.in: Add support for building shared libraries under Darwin.
23650 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
23651 the low level EH init subprogram to be called from __gnat_initialize.
23653 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
23654 indicates which options to pass to the archive indexer.
23656 * mlib-utl.adb: Add support for calling ranlib with additional
23657 options. This is needed for instance under Mac OS X.
23658 (Ranlib_Options): New global variable, used to store the potential
23659 options to pass to ranlib.
23660 (Ar): Use Ranlib_Options when spawning ranlib.
23661 (Initialize): Set the value of ranlib option.
23663 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
23665 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
23666 instead of 8K, to reflect the real potential needs for stack-checking
23669 2004-10-26 Pascal Obry <obry@gnat.com>
23671 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
23673 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
23674 Windows only the initial thread stack size can be set so it is good to
23675 start we a low stack size.
23676 The OS will adjust the size as needed.
23678 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
23679 Nicolas Setton <setton@act-europe.fr>
23681 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
23682 "__unix__" instead of "unix".
23683 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
23684 sections were just mistakenly ignored. The former is
23685 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
23686 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
23687 of hpux. This prevents an unwanted definition of the symbol
23688 convert_addresses in adaint.o.
23690 2004-10-26 Gary Dismukes <dismukes@gnat.com>
23692 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
23693 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
23695 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23697 * a-filico.ads, a-filico.adb: fix incorrect header.
23699 2004-10-26 Javier Miranda <miranda@gnat.com>
23701 * a-ststio.ads: Fix typo in identifier
23703 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23705 * sem_ch4.adb: Minor reformatting.
23707 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23709 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
23710 enabled, check the result of unary and binary operations when the
23711 expression is the right-hand side of an assignment.
23713 2004-10-26 Vincent Celier <celier@gnat.com>
23715 * clean.adb (Delete): Do not output warnings when in quiet output and
23716 not in verbose mode.
23717 (Force_Deletions): New Boolean flag, defaulted to False
23718 (Delete): Only delete a file if it is writable, and when
23719 Force_Deletions is True.
23720 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
23721 (Usage): Line for new switch -f
23722 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
23725 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23727 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
23728 JM type only if its size matches that of the wrapper. When a size is
23729 prescribed and the field is not aliased, remove the wrapper of a JM
23730 type only if the size is not greater than that of the packed array.
23731 (gnat_to_gnu_entity): Change the extension of packed array wrappers
23734 2004-10-26 Geert Bosch <bosch@gnat.com>
23736 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
23737 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
23738 (Pred): Implement in terms of Succ.
23740 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23742 * exp_aggr.adb (Safe_Component): An aggregate component that is an
23743 unchecked conversion is safe for in-place use if the expression of the
23744 conversion is safe.
23745 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
23746 be expandable in place even if the aggregate does not come from source.
23747 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
23748 designated object of an allocator in place, rather than building it
23749 first on the stack. The previous scheme forces a full copy of the array,
23750 and may be altogether unsusable if the size of the array is too large
23751 for stack allocation.
23753 2004-10-26 Robert Dewar <dewar@gnat.com>
23755 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
23756 compares if the component is atomic.
23758 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
23759 array assignment if the component type is atomic.
23761 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23762 Eric Botcazou <ebotcazou@act-europe.fr>
23764 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
23765 is aliased and is a by_reference type, do not pass by copy.
23766 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
23767 detect whether the call is in the right side of an assignment or
23768 the expression of an object declaration. Recurse on component
23769 association within aggregates.
23770 Call it in the condition that determines whether the temporary is
23771 necessary for correct stack-checking.
23773 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23775 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
23776 RACW_Type, used in the PolyORB version.
23777 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
23778 version and the GARLIC version.
23780 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
23781 Rename RCI_Info to RCI_Locator for better consistency between the
23782 GARLIC and PolyORB versions of the distributed systems annex.
23783 (DSA_Implementation_Name): This enumeration lists the possible
23784 implementations of the Partition Communication Subsystem for the
23785 Distributed Systems Annex (DSA). The three available implementations
23786 are the dummy stub implementation (No_DSA), and two versions based on
23787 two different distribution runtime libraries: GARLIC and PolyORB. Both
23788 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
23790 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
23793 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
23794 between the GARLIC and PolyORB versions of the distributed systems
23796 Remove RE_Unbounded_Reclaim_Pool since it is unused.
23798 2004-10-26 Gary Dismukes <dismukes@gnat.com>
23800 * gnat1drv.adb: Suppress calling the back end when
23801 Frontend_Layout_On_Target is true.
23803 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23805 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
23806 Set_Read_Only): New subprograms.
23807 These new routines allow the user to set or unset the Owner execute
23808 and Owner write permission flags on a file.
23810 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
23811 GNAT.OS_Lib.Set_Executable instead of rolling our own.
23813 2004-10-26 Matthew Gingell <gingell@gnat.com>
23815 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
23817 2004-10-26 Pascal Obry <obry@gnat.com>
23819 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
23820 memory before the faulting page we properly test the process read
23821 access for this address using appropriate Win32 routine.
23822 (HPUX sections): guard with "__hpux__" instead of "hpux".
23824 2004-10-26 Robert Dewar <dewar@gnat.com>
23826 * lib-xref.adb (Generate_Reference): Don't complain about reference to
23827 entry parameter if pragma Unreferenced set, since we do not properly
23828 handle the case of multiple parameters.
23830 2004-10-26 Vincent Celier <celier@gnat.com>
23832 * prj-env.adb: (Contains_ALI_Files): New Boolean function
23833 (Ada_Objects_Path.Add): For a library project, add to the object path
23834 the library directory only if there is no object directory or if the
23835 library directory contains ALI files.
23836 (Set_Ada_Paths.Add.Recursive_Add): Ditto
23838 2004-10-26 Vincent Celier <celier@gnat.com>
23840 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
23841 extension of library projects.
23843 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
23844 path defaults to ".:<prefix>/lib/gnat".
23845 (Parse): For an extending all project, allow direct import of a project
23846 that is virtually extended.
23848 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
23849 the specified name is directly imported, return its ID. Otherwise, if
23850 an extension of this project is imported, return the ID of the
23853 2004-10-26 Robert Dewar <dewar@gnat.com>
23855 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
23856 (Sub3): New procedure, used by Scaled_Divide
23857 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
23858 correct more than one instance of failure to propagate carries
23860 (Double_Divide): Handle overflow case of largest negative number
23861 divided by minus one.
23863 * s-arit64.ads (Double_Divide): Document that overflow can occur in
23864 the case of a quotient value out of range.
23867 2004-10-26 Robert Dewar <dewar@gnat.com>
23869 * s-bitops.adb (Bit_Eq): Remove redundant check.
23871 * s-bitops.ads: Minor comment updates
23872 Change some occurrences of Address to System.Address
23874 * s-carsi8.ads: Fix minor cut-and-paste error in comments
23876 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23878 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
23879 accessibility check to prefix that is a protected operation.
23881 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23883 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
23884 empty, post message on stub.
23886 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23887 Javier Miranda <miranda@gnat.com>
23889 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
23890 current instance appears within a unit that is directly in the context
23892 Used to determine whether the body of the instance should be analyzed
23893 immediately after its spec, to make its subprogram bodies available
23894 for front-end inlining.
23895 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
23896 constraint is not allowed on the component type (AARM 12.5.3(3))
23898 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23900 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
23901 'Storage_Pool): enhance, document & limit detection of non-sharable
23904 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
23906 * s-pooglo.ads: Add more documentation now that this pool is properly
23909 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23911 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
23912 or protected type with discriminants, do not constrain the
23913 corresponding record type if the subtype declaration has no
23914 discriminant constraints. This can be the case in source code, or in
23915 the subtype declaration created to rename an actual type within an
23918 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23920 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
23921 different kind of stub (possibly wrong name for file), do not check
23923 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
23924 includes call to some function that returns an unconstrained type, do
23927 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23929 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
23930 appear in the code for the main unit. Dependencies among units in the
23931 context of the main unit are established when those other units are
23932 compiled. Otherwise spurious elaboration constraints can generate
23933 incorrect elaboration circularities.
23935 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23936 Ed Schonberg <schonberg@gnat.com>
23938 * sem_util.adb (Is_Aliased_View): Defend against the case where this
23939 subprogram is called with a parameter that is not an object name. This
23940 situation arises for some cases of illegal code, which is diagnosed
23941 later, and in this case it is wrong to call Is_Aliased, as that might
23942 cause a compiler crash.
23943 (Explain_Limited_Type): Refine previous fix to include
23944 inherited components of derived types, to provide complete information.
23946 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
23947 is the prival for a protected object.
23948 It is necessary to mark this entity as a variable, in addition to
23949 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
23950 modified to avoid checking the Aliased flag on entities that are not
23951 objects. (Checking that flag for non-objects is erroneous and could
23952 lead to a compiler crash).
23954 2004-10-26 Robert Dewar <dewar@gnat.com>
23956 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
23957 X_Frac = 0.5, then we know that the number X must be positive.
23958 (Succ): Remove the same redundant test, and also fix the primary test
23959 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
23961 (Decompose): Add fuller comments to spec
23963 2004-10-26 Pascal Obry <obry@gnat.com>
23965 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
23966 validity (process must have read access). Set to 0 in all other cases.
23967 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
23968 violation on Win32.
23969 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
23970 segmentation violation.
23972 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23974 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
23975 whose type is a constructed subtype of an aliased object with an
23976 unconstrained nominal subtype, convert the actual to the constructed
23977 subtype before taking its address.
23979 2004-10-26 Vincent Celier <celier@gnat.com>
23981 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
23982 (Is_Path_Name_Case_Sensitive): New function
23984 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
23985 (Base_Name, Simple_Name, Current_Directory, Compose,
23986 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
23989 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23990 Vasiliy Fofanov <fofanov@act-europe.fr>
23991 Vincent Celier <celier@gnat.com>
23993 * gnat_ugn.texi: Generalize "finding memory problems" section into a
23994 "memory management issues" section and document some of the useful
23995 memory pools provided as part of the GNAT library.
23996 Remove "virtual" from declaration of A::method2 in
23997 the simple example of Ada/C++ mixed system.
23998 Library Projects may be virtually extended: their virtual extensions
23999 are not Library Projects.
24000 Added section on extending project hierarchies.
24002 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
24004 * adaint.c (__gnat_get_libraries_from_registry): Cast value
24006 (__gnat_portable_spawn): Remove const.
24008 * mingw32.h (MAXPATHLEN): Check for previous definition.
24010 2004-10-17 Matthias Klose <doko@debian.org>
24012 * gnatvsn.ads: Set gnat library version to 4.0.
24014 2004-10-05 Vincent Celier <celier@gnat.com>
24016 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
24018 2004-10-04 Laurent Guerby <laurent@guerby.net>
24021 * Makefile.in: Define and use RANLIB_FLAGS.
24023 2004-10-04 Pascal Obry <obry@gnat.com>
24025 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
24026 other x86 platforms).
24028 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
24030 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
24031 in general and triggers stack alignment adjustment for thread entry
24032 points on targets where this is necessary.
24034 2004-10-04 Bernard Banner <banner@gnat.com>
24037 * Makefile.in: Add section for powerpc linux
24038 Add variant i-vxwork-x86.ads
24040 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
24042 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
24044 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
24045 table registration calls when need be. Ensures no reference to the crt
24046 ctors symbol are issued in the SJLJ case, which avoids possible
24047 undefined symbol errors in the case of modules to be statically linked
24050 2004-10-04 Javier Miranda <miranda@gnat.com>
24052 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
24053 in-line the code corresponding to subprogram Analyze_Actuals. In
24054 addition, analyze the actuals only in case of subprogram call.
24056 2004-10-04 Ed Falis <falis@gnat.com>
24058 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
24060 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
24062 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
24063 in the documentation.
24065 2004-10-04 Robert Dewar <dewar@gnat.com>
24067 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
24069 (Analyze_Block_Statement): Add circuitry to detect following dead code
24070 (Check_Unreachable_Code): Handle case of block exit
24072 2004-10-04 Robert Dewar <dewar@gnat.com>
24074 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
24075 (XMatchD): Avoid warning for Logic_Error call
24077 2004-10-04 Robert Dewar <dewar@gnat.com>
24079 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
24080 consider expressions buried within a procedure actual to be an actual.
24081 This caused some blowups with uses of packed slices within a procedure
24084 2004-10-04 Robert Dewar <dewar@gnat.com>
24086 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
24087 longer need to be initialized to zero.
24088 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
24089 initialized to zero.
24091 * checks.adb (Expr_Known_Valid): Packed arrays are now always
24092 considered valid, even if the representation is modular. That's correct
24093 now that we no longer initialize packed modular arrays to zero.
24095 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
24096 suffixes. These are now documented as the only cases in which the
24097 debugger ignores outer records.
24098 Previously, the spec allowed arbitrary suffixes for this purpose.
24099 Change name of LJM to JM for packed array pad records
24100 Create separate section on packed array handling, and add a whole new
24101 set of comments to this section describing the situation with packed
24102 modular types and justification requirements depending on endianness.
24104 2004-10-04 Robert Dewar <dewar@gnat.com>
24106 * a-except.adb: Add a comment for last change
24108 * einfo.ads: Minor spelling correction in comment
24110 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
24112 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
24115 * sem_util.ads: Minor comment update
24117 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24119 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
24120 Inline_Always when in Configurable_Run_Time mode.
24122 * sem_prag.adb (Process_Convention): If entity is an inherited
24123 subprogram, apply convention to parent subprogram if in same scope.
24124 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
24125 when in Configurable_Run_Time mode.
24127 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24129 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
24130 class_wide type after component list has been inherited.
24132 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24134 * sem_ch12.adb (Check_Generic_Actuals): New predicate
24135 Denotes_Previous_Actual, to handle properly the case of a private
24136 actual that is also the component type of a subsequent array actual.
24137 The visibility status of the first actual is not affected when the
24138 second is installed.
24139 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
24140 make fully recursive the treatment of formals of packages declared
24142 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
24143 the above on exit from an instantiation.
24144 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
24145 current instantiation which is now complete.
24146 (Analyze_Package_Instantiation): No instantiated body is needed if the
24147 main unit is generic. Efficient, and avoid anomalies when a instance
24148 appears in a package accessed through rtsfind.
24150 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24152 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
24153 do not generate a declaration for a temporary if the call is part of a
24154 library-level instantiation.
24156 2004-10-04 Ed Schonberg <schonberg@gnat.com>
24158 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
24159 searching for a limited component to flag.
24161 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
24162 expansion of Input, to account for the fact that the implicit call
24163 generated by the attribute reference must freeze the user-defined
24164 stream subprogram. This is only relevant to 'Input, because it can
24165 appear in an object declaration, prior to the body of the subprogram.
24167 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
24168 expansion can proceed and further errors uncovered.
24169 (Minor clean up): Fix cases of using | instead of \ for continuation
24172 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24174 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
24176 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
24177 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
24178 Use gcc_assert and gcc_unreachable.
24180 * decl.c (gnat_to_gnu_entity, case object): Check and process a
24181 specified alignment before validating size.
24182 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
24183 stripped-down declaration for the type of the inner field when making
24186 * utils.c (finish_record_type): Do not compute the size in units
24187 incrementally. Instead compute it once for the rep clause case.
24188 Use gcc_assert and gcc_unreachable.
24190 2004-10-04 Vincent Celier <celier@gnat.com>
24192 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
24194 (Is_Valid_Path_Name): Take '/' as a directory separator.
24196 2004-10-04 Vincent Celier <celier@gnat.com>
24198 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
24199 (Extended_Project) only if Extended_Project is defined, to avoid
24201 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
24203 (Parse_Single_Project): Ditto.
24205 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
24206 Add_To_Project_Path for virtual projects.
24208 2004-10-04 Vincent Celier <celier@gnat.com>
24210 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

24213 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
24214 parameter Options_2.
24216 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
24217 Build_Dynamic_Library with an empty Options_2.
24219 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
24222 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
24223 directory separator, if any.
24224 (Gprmake): Do not allow mains on the command line for library projects.
24225 Do not attempt to link when the project is a library project.
24226 (Library_Opts): New table to store Library_Options.
24227 (Build_Library): If Library_Options is specified, pass these options
24228 when building a shared library.
24230 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
24232 * s-tposen.adb (Service_Entry): The object must be always unlocked at
24233 the end of this procedure now that the unlock operation was inserted
24236 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
24238 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
24239 corresponding to the Preallocated_Stacks flags in System.
24240 (Get_Target_Parameters): Including the processing for
24241 Preallocated_Stacks.

24251 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
24252 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
24253 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
24254 used to signal whether the compiler creates the required stacks and
24255 descriptors for the different tasks (when True) or it is done by the
24256 underlying operating system at run time (when False).
24257 It is initially set to False in all targets.
24259 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
24260 if it is supported by the target.
24261 (Make_Task_Create_Call): Pass the stack address if it has been
24262 previously created. Otherwise pass a Null_Address.
24264 * snames.adb: Add _stack.
24266 * snames.ads: Add Name_uStack. Required to allow the expander to
24267 statically allocated task stacks.
24269 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
24270 Stack_Address argument.
24271 Check that its value is equal to Null_Address because this target does
24272 not support the static stack allocation.

24281 * exp_dist.adb: Split declaration of asynchronous flag out of
24282 Add_RACW_Read_Attribute.
24283 Minor reformatting for better alignment with PolyORB version.
24284 Store the entity for the asynchronous flag of an RACW, rather than the
24285 expression, in the asynchronous flags table. This will allow this flag
24286 to be used in other subprograms beside Add_RACW_Read_Attribute.
24288 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
24290 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

24294 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
24295 sockets constant MSG_NOSIGNAL (Linux-specific).
24296 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
24297 all Send operations.
24298 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
24299 from trigerring SIGPIPE.
24300 Rename components to avoid clash with Ada 2005 possible reserved
24302 (Check_Selector): When the select system call returns with an error
24303 condition, propagate Socket_Error to the caller.

24313 instead do this at freeze time (we won't do it if there is an address
24315 Change "pragma inline" to "pragma Inline" in information and error
24317 Minor reformatting.
24319 * freeze.adb (Check_Address_Clause): Remove previous change, not the
24320 right way of doing things after all.
24321 (Freeze_Entity): For object, set Is_Public for imported entities
24322 unless there is an address clause present.
24324 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
24326 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
24327 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
24328 ensures proper handling of types with rep clauses, which might have
24329 their TYPE_SIZE set already.
24331 2004-09-21 Robert Dewar <dewar@gnat.com>
24333 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
24334 packed array types in both little- and big-endian cases. This change
24335 ensures that we no longer count on the unused bits being initialized
24336 for such types (and in particular ensures that equality testing will
24337 only read the relevant bits).
24338 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
24339 These changes mean that we no longer need to initialize small packed
24341 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
24342 optimization to an LJM field as to its parent field.
24344 * ada-tree.h, trans.c, utils.c, utils2.c:
24345 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
24347 2004-09-20 Jan Hubicka <jh@suse.cz>
24349 * utils.c (gnat_finalize): Remove.
24350 (end_subprog_body): Directly call cgraph_finalize_function;
24351 do not lower the nested functions.
24353 2004-09-20 Robert Dewar <dewar@gnat.com>
24356 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
24357 if an address clause is present, since that means that the Import
24360 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
24362 * 5tsystem.ads: Removed, no longer used.
24364 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
24365 Zack Weinberg <zack@codesourcery.com>
24367 * ada-tree.def: Use tree_code_class enumeration constants
24368 instead of code letters.

24386 an existing directory.
24387 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
24388 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
24389 Convert the result to File_Size.
24391 * prj.ads: (Project_Error): New exception
24393 * prj-attr.adb: Except in procedure Initialize, Fail comes from
24394 Prj.Com, not from Osint.
24395 (Attrs, Package_Attributes): Tables moved to private part of spec
24396 (Add_Attribute, Add_Unknown_Package): Moved to new child package
24398 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
24399 Prj.Project_Error after call to Fail.
24400 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
24401 Fail. Check that package name is not already in use.
24403 * prj-attr.ads: Comment updates to indicate that all subprograms may be
24404 used by tools, not only by the project manager, and to indicate that
24405 exception Prj.Prj_Error may be raised in case of problem.
24406 (Add_Unknown_Package, Add_Attribute): Moved to new child package
24408 (Attrs, Package_Attributes): Table instantiations moved from the body to
24409 the private part to be accessible from Prj.Attr.PM body.
24411 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
24412 from new package Prj.Attr.PM.
24413 (Parse_Attribute_Declaration): Call Add_Attribute from new package
24416 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
24418 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
24419 instead of Elaboration_Checks).
24421 * a-calend.adb: Minor reformatting

24464 pragmas recognized by GNAT.
24466 * gnat_rm.texi: Document pragma Detect_Blocking.
24468 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
24469 raise Program_Error if called from a protected operation.
24471 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
24472 the protected action nesting level.
24473 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
24474 protected action nesting level.
24475 (Unlock): When pragma Detect_Blocking is active decrease the protected
24476 action nesting level.
24478 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
24479 Protected_Action_Nesting.
24481 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
24482 Common_ATCB record. It contains the dynamic level of protected action
24483 nesting for each task. It is needed for checking whether potentially
24484 blocking operations are called from protected operations.
24485 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
24486 Detect_Blocking is active or not in the partition.
24488 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

24498 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
24499 raise Program_Error if called from a protected operation, and increase
24500 the protected action nesting level.
24501 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
24502 Program_Error if called from a protected operation, and increase the
24503 protected action nesting level.

24509 the protected action nesting level.
24510 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
24511 Program_Error if called from a protected operation, and increase the
24512 protected action nesting level.

24518 protected action nesting level.
24520 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
24521 insertion of the statement raising Program_Error. The run time
24522 contains the required machinery for handling that.
24524 * sem_util.ads: Change comment associated to procedure
24525 Check_Potentially_Blocking_Operation.
24526 This procedure does not insert a call for raising the exception because
24527 that is currently done by the run time.
24529 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
24531 * init.c: Add the global variable __gl_detect_blocking that indicates
24532 whether pragma Detect_Blocking is active (1) or not (0). Needed for
24533 making the pragma available at run time.
24534 (__gnat_set_globals): Pass and update the detect_blocking parameter.
24536 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
24537 pragma Detect_Blocking is active.
24539 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
24541 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
24542 DB is found in the ali file. Any unit compiled with pragma
24543 Detect_Blocking active forces its effect in the whole partition.
24545 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
24546 Detect_Blocking is active and delay is called from a protected
24549 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
24550 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
24551 Detect_Blocking is active (0 otherwise).
24552 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
24553 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
24556 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
24558 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
24559 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
24562 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
24563 (Register_Receiving_Stub): Add Subp_Info formal parameter.
24564 Update API in placeholder implemetation of s-parint to reflect changes
24565 in distribution runtime library.
24567 * sem_ch3.adb (Expand_Derived_Record): Rename to
24568 Expand_Record_Extension.
24570 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
24571 primitive operations of potentially distributed object types that have
24572 non-controlling anonymous access formals.
24574 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
24576 New implementation of expansion for remote access-to-subprogram types,
24577 based on the RACW infrastructure.
24578 This version of sem_dist is compatible with PolyORB/DSA as well as
24581 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
24582 Asynchrronous that applies to a remote access-to-subprogram type, mark
24583 the underlying RACW type as asynchronous.
24585 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
24586 __gnat_using_gnu_linker to 1.
24588 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
24589 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
24590 GNAT.Perfect_Hash_Generators, and remove the empty
24591 GNAT.Perfect_Hash package.
24593 * atree.adb: Minor reformatting
24595 * exp_ch3.adb (Expand_Derived_Record): Rename to
24596 Expand_Record_Extension.
24597 (Build_Record_Init_Proc.Build_Assignment): The default expression in
24598 a component declaration must remain attached at that point in the
24599 tree so New_Copy_Tree copies it if the enclosing record type is derived.
24600 It is therefore necessary to take a copy of the expression when building
24601 the corresponding assignment statement in the init proc.
24602 As a side effect, in the case of a derived record type, we now see the
24603 original expression, without any rewriting that could have occurred
24604 during expansion of the ancestor type's init proc, and we do not need
24605 to go back to Original_Node.
24607 * exp_ch3.ads (Expand_Derived_Record): Rename to
24608 Expand_Record_Extension.
24610 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
24611 Returns the RACW type used to implement a remote access-to-subprogram
24613 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
24614 New subprograms. Used to create a proxy tagged object for a remote
24615 subprogram. The proxy object is used as the designated object
24616 for RAS values on the same partition (unless All_Calls_Remote applies).
24617 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
24618 System.Partition_Interface.Get_Unique_Remote_Pointer.
24619 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
24620 Renamed from Add_RAS_*_Attribute.
24621 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
24623 New implementation of expansion for remote access-to-subprogram types,
24624 based on the RACW infrastructure.
24626 * exp_dist.ads (Copy_Specification): Update comment to note that this
24627 function can copy the specification from either a subprogram
24628 specification or an access-to-subprogram type definition.
24630 2004-09-09 Ed Schonberg <schonberg@gnat.com>
24632 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
24633 in an instance, between an explicit subprogram an one inherited from a
24634 type derived from an actual.
24636 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
24637 add a polling call if the subprogram is to be inlined by the back-end,
24638 to avoid repeated calls with multiple inlinings.
24640 * checks.adb (Apply_Alignment_Check): If the expression in the address
24641 clause is a call whose name is not a static entity (e.g. a dispatching
24642 call), treat as dynamic.
24644 2004-09-09 Robert Dewar <dewar@gnat.com>
24646 * g-trasym.ads: Minor reformatting
24648 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
24649 packed arrays, since unused bits are expected to be zero for a

24888 for a global aliased object with a variable size and an unconstrained
24889 nominal subtype, pretend there is no initializer if the one we have is
24890 incomplete, and avoid referencing an inexistant component in there. The

24915 unit, this is an attempt to inline a construct that is not available in
24916 the current restricted mode, so abort rather than trying to continue.
24918 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
24919 discriminants that rename those of the parent, recover names of
24920 original discriminants for the constraint on the full view of the

24951 returning C.int, to avoid using a derived boolean type.
24953 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

24982 ignore overflows on low and high bounds of an index to also account for
24983 differences in signedness between sizetype and gnu_index_subtype.
24984 These are as legitimate as the ones caused by a lower TYPE_PRECISION

28901 complete assignment subtree which is now unnecessary, as the expansion
28902 of inlined call has been improved to preserve a consistent assignment

28904 after checks have been applied, or else unnecessary checks will

29163 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
29165 * osint.adb (Executable_Prefix): Set Exec_Name to the current
29166 executable name when not initialized. Otherwise, use its current value.
29168 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
29169 initialize it to another executable name than the current one. This
29170 allows to configure paths for an executable name (gnatmake) different
29171 from the current one (gnatdist).
29173 2004-03-29 Ed Schonberg <schonberg@gnat.com>
29175 * exp_ch6.adb (Expand_Call): A call to a function declared in the
29176 current unit cannot be inlined if it appears in the body of a withed
29177 unit, to avoid order of elaboration problems in gigi.
29179 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
29180 information for protected (wrapper) operation as well, to simplify gdb
29183 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
29184 protected body, indicate that the entity for the generated spec comes
29185 from source, to ensure that references are properly generated for it.
29186 (Build_Body_To_Inline): Do not inline a function that returns a

29193 that renames an equality operator and the operands are overloaded,
29194 resolve them with the declared formal types, before rewriting as an
29197 2004-03-29 GNAT Script <nobody@gnat.com>

29220 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
29222 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
29223 attribute reference does not denote a subtype, it can be any
29224 expression that has a classwide type, potentially after an implicit
29225 dereference. In particular, the prefix can be a view conversion for
29226 a classwide type (for which Is_Object_Reference holds), but it can
29227 also be a value conversion for an access-to-classwide type. In the
29228 latter case, there is an implicit dereference, and the original node
29229 for the prefix does not verify Is_Object_Reference.
29231 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
29232 conversion of a discriminant-dependent component of a mutable object
29235 2004-03-25 Ed Schonberg <schonberg@gnat.com>
29237 * freeze.adb (Freeze_Entity): When an inherited subprogram is
29238 inherited, has convention C, and has unconstrained array parameters,
29239 place the corresponding warning on the derived type declaration rather
29240 than the original subprogram.
29242 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
29243 indication on renaming declaration, if formal has a box and actual
29246 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
29247 determine whether to generate an implicit or explicit reference to
29248 the renamed entity.
29250 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
29251 subprogram renaming comes from a defaulted formal subprogram in an
29254 2004-03-25 Gary Dismukes <dismukes@gnat.com>
29256 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
29257 value expressions to ensure that calls within a component definition
29258 will be checked (since those are evaluated during the record type's

29309 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
29310 declaration for a child subprogram body that acts as a spec, indicate
29311 that the entity in the declaration needs debugging information.
29313 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
29314 full view if the subtype is created for a constrained record component;
29315 gigi has enough information to construct the record, and there is no
29316 place in the tree for the declaration.
29318 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
29319 serial number for the dummy body that is built for analysis, to avoid
29320 inconsistencies in the generation of internal names when compiling
29323 2004-03-22 Thomas Quinot <quinot@act-europe.fr>

29352 gnat_ug_wnt.texi: Regenerate.
29354 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
29356 * ada-tree.h: Update copyright notice.
29357 Minor reformatting.
29359 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
29361 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
29362 as regular exception objects and not as mere integers representing the
29363 condition code. The latter approach required some dynamics to mask off
29364 severity bits, which did not fit well into the GCC table based model.
29365 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
29366 exception data objects. We don't it and it would conflict with the other
29367 external symbol we have to generate for such exceptions.
29369 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
29370 the special code for VMS exceptions, since these are now represented
29371 as regular exceptions objects.
29373 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29375 * decl.c (debug_no_type_hash): Remove.

29379 2004-03-19 Laurent Guerby <laurent@guerby.net>
29381 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
29382 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
29384 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29386 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

29401 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
29402 Specific.Set instead of direct call to e.g pthread_setspecific.
29404 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
29406 * adaint.c: Update comments.
29408 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
29409 GNATLIB_SHARED for FreeBSD.
29411 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
29413 * init.c [VxWorks]: Do not fix the stack size for the environment task.
29414 When needed (stack checking) the stack size is retrieved
29415 from the VxWorks kernel.
29417 * Makefile.in: Flag -nostdinc is required when building the run time
29418 for avoiding looking for files in the base compiler.
29419 Add the VxWorks specific version of the package body for
29420 System.Stack_checking.Operations (5zstchop.adb).
29422 * Make-lang.in: Add the object file for
29423 System.Stack_Checking.Operations.
29425 * Makefile.rtl: Add object file for the package
29426 System.Stack_Checking.Operations.
29428 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
29430 * s-stache.ads, s-stache.adb: Move the operations related to stack
29431 checking from this package to package System.Stack_Checking.Operations.
29432 This way, stack checking operations are only linked in the final
29433 executable when using the -fstack-check flag.
29435 2004-03-18 Doug Rupp <rupp@gnat.com>
29437 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

29447 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
29448 the procedures Add_To_Path_File.
29449 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
29450 making sure that each directory is present only once and, for object
29451 dirs, when a directory already present is added, the duplicate is
29452 removed and the directory is always put as the last in the table.
29453 Write the path files at the end of these accumulations.
29455 * prj-nmsc.adb (Record_Source): Add source file name in hash table
29456 Files_Htable for all sources.
29458 * prj-proc.adb (Process): Remove restrictions between not directly
29459 related extending projects.

29476 * sem_warn.adb (Check_References): For a warning on a selected
29477 component that does not come from source, locate an uninitialized
29478 component of the record type to produce a more precise error message.
29480 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
29482 * 3zsoccon.ads: Fix multicast options.

29490 pragma used for a private type.
29492 * lib-xref.adb (Generate_Reference): Do not generate warning if
29493 reference is in a different unit from the pragma Unreferenced.
29495 * 5vtpopde.adb: Minor reformatting
29496 Fix casing of To_Task_ID
29498 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
29499 flag if we have an unchecked conversion to an access type in the same
29502 2004-03-15 Geert Bosch <bosch@gnat.com>
29504 * a-ngcoty.adb (Modulus): In alternate formula for large real or
29505 imaginary parts, use Double precision throughout.
29507 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
29508 we want to be able to compile run-time with -gnata for testing, but
29509 this may also be instantiated in user code that is compiled with -gnata.
29511 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
29513 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
29514 codes. Having a separate type for this is useful to enforce consistency
29515 throughout the various run-time units.
29516 (Exception_Data): Use Exception_Code for Import_Code.
29518 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
29519 Natural and Integer in various places.

29521 with the severity bits masked off.
29522 (Register_VMS_Exception): Handle the additional exception data pointer

29526 component, now reflected by an exported accessor.
29527 (is_handled_by): New routine to compute whether the propagated
29528 occurrence matches some handler choice specification. Extracted out of
29529 get_action_description_for, and expanded to take care of the VMS
29531 (get_action_description_for): Use is_handled_by instead of an explicit
29532 complex condition to decide if the current choice at hand catches the
29533 propagated occurrence.
29535 * raise.h (Exception_Code): New type for C.
29537 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
29538 System.Standard_Library.Exception_Code, to allow references from the
29539 pragma import/export expander.
29541 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
29542 New accessors to allow easy access to GNAT exception data
29544 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
29545 redundant Handled_By_Others component, helper for the personality
29546 routine which will now be able to call the appropriate exception data

30553 Don't make a bitfield if the field is to be addressable.
30554 Always set a size for the field if the record is packed, to ensure the
30555 checks for bitfield creation are triggered.
30556 (finish_record_type): During last pass over the fields, clear
30557 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
30558 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P

30607 error when there are unusual characters (such as '!') in the paths.
30609 * Makefile.generic: When there are sources in Ada and the main is in
30610 C/C++, invoke gnatmake with -B, instead of -z.

31016 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
31017 N_String_Literal node always references an E_String_Literal_Subtype
31018 entity. This may not be true in the future.
31019 (Possible_Bit_Aligned_Component): Move processing of
31020 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
31022 * exp_ch6.adb (Expand_Thread_Body): Pick up

31027 (Type_May_Have_Bit_Aligned_Components): New function.

31067 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
31068 ineffective elaborate all pragmas on non-visible packages (this
31069 happened when a renamed subprogram was called). Now the elaborate all
31070 always goes on the package containing the renaming rather than the one
31071 containing the renamed subprogram.
31073 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
31074 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

31099 * make.adb (Gnatmake): Special process for files to compile/check when
31100 -B is specified. Fail when there are only foreign mains in attribute

31133 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
31135 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
31136 all attributes, including read-only attribute.

31141 library naming scheme.

31295 Created and exported __gnat_map_signal to support signal -> exception
31296 mapping that is dependent on the VxWorks version.

31327 2003-12-11 Ed Schonberg <schonberg@gnat.com>
31329 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
31330 bounds of a loop, create a separate block in order to generate proper
31331 cleanup actions to prevent memory leaks.
31333 * sem_res.adb (Resolve_Call): After a call to
31334 Establish_Transient_Scope, the call may be rewritten and relocated, in
31335 which case no further processing is needed.

31350 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
31353 2003-12-08 Robert Dewar <dewar@gnat.com>
31355 * 7sintman.adb: Minor reformatting
31357 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
31358 standard linker options to get standard libraries linked. We now plan
31359 to provide dummy versions of these libraries to match the appropriate
31360 configurable run-time (e.g. if a library is not needed at all, provide
31361 a dummy empty library).
31363 * targparm.ads: Configurable_Run_Time mode no longer affects linker
31364 options (-L parameters and standard libraries). What we plan to do is
31365 to provide dummy libraries where the libraries are not required.
31367 * gnatbind.adb: Minor comment improvement
31369 2003-12-08 Javier Miranda <miranda@gnat.com>
31371 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
31372 aggregate in the parent. Otherwise constants with limited aggregates

31374 It is required to call the corresponding IP subprogram in case of
31375 default initialized components.
31376 (Gen_Assign): In case of default-initialized component, generate a
31377 call to the IP subprogram associated with the component.
31378 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
31379 of aggregate with default initialized components.
31380 (Has_Default_Init_Comps): Improve implementation to recursively check
31381 all the present expressions.
31383 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
31384 to indicate that the initialization call corresponds to a
31385 default-initialized component of an aggregate.
31386 In case of default initialized aggregate with tasks this parameter is
31387 used to generate a null string (this is just a workaround that must be
31388 improved later). In case of discriminants, this parameter is used to
31389 generate a selected component node that gives access to the discriminant
31392 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
31393 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
31394 allocated aggregates with default-initialized components.
31396 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
31397 the box notation is used in positional aggregates.

31439 Process nodes N_Comment.
31441 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
31442 without comments and there are some comments, set the flag
31443 Unkept_Comments to True.
31444 (Scan): If there are comments, set the flag Unkept_Comments to True and
31445 clear the comments.
31446 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
31447 (Next_End_Nodes: New table

31475 Comment_Id and set Token to Tok_Comment when scanning a comment.
31476 (Set_Comment_As_Token): New procedure
31478 * sinput-p.adb: Update Copyright notice
31479 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

31484 * sem_aggr.adb: Add dependence on Exp_Tss package
31485 Correct typo in comment
31486 (Resolve_Aggregate): In case of array aggregates set the estimated
31487 type of the aggregate before calling resolve. This is needed to know
31488 the name of the corresponding IP in case of limited array aggregates.
31489 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
31490 in case of default initialized array components.
31492 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

31512 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
31513 they are automatically generated by Make-lang.in and cause nothing but
31514 maintenance troubles.
31516 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
31518 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

31532 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
31533 to ensure that the kernel fills in the interrupted context structure
31534 before calling a signal handler, which is necessary to be able to
31535 unwind past it. Update the copyright notice.
31537 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
31539 * a-elchha.ads: New file.
31541 * a-elchha.adb: New default last chance handler. Contents taken from
31542 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.

31623 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
31624 included in HIE_NONE_TARGET_PAIRS.
31626 2003-12-03 Ed Schonberg <schonberg@gnat.com>
31629 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
31630 is legal in an instance, because legality is cheched in the template.
31633 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
31634 appplied to an unchecked conversion of a formal parameter.
31637 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

31651 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
31652 so that the debugger can reliably access the value of the parameter,
31653 and therefore is able to display the exception name when an exception
31654 breakpoint is reached.
31656 2003-12-01 Thomas Quinot <quinot@act-europe.fr>
31658 * fmap.adb: Fix typo in warning message.

32993 Remove the test against being in No_Run_Time_Mode before generating a
32994 call to Register_Tag. It is redundant with the test against the
32995 availability of the function Register_Tag.
32997 2003-10-24 Vincent Celier <celier@gnat.com>

33011 information, check that the source exists and, if it does, that the path

35201 (title page): Remove date.
35202 (general) Add @./@: where approriate, and two spaces after the
35203 full stop at the end of a sentence. Use @samp markup when
35204 referring concrete lexical entities (keywords, attribute names
35205 etc.), and @syntax for ARM grammar elements. Use @r for English

35282 Add 2001 to copyright date
35284 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
35285 need to force universal inlining for these cases.
35287 2001-12-19 Arnaud Charlet <charlet@gnat.com>
35289 * s-taprob.adb: Minor clean ups so that this unit can be used in
35292 * exp_ch7.adb: Allow use of secondary stack in HI mode.

35316 the argument of an initialization procedure.
35318 * trans.c (tree_transform, case of arithmetic operators): If result
35319 type is private, the gnu_type is the base type of the full view,
35320 given that the full view itself may be a subtype.
35322 2001-12-17 Robert Dewar <dewar@gnat.com>
35324 * sem_res.adb: Minor reformatting

35590 2001-12-17 Laurent Pautet <pautet@gnat.com>
35593 Fix comment of Shutdown_Socket and Close_Socket. These functions
35594 should not fail silently because if they are called twice, this
35595 probably means that there is a race condition in the user program.
35596 Anyway, this behaviour is consistent with the rest of this unit.
35597 When an error occurs, an exception is raised with the error message
35598 as exception message.

36932 instead of the previous simple checksum algorithm.
36933 (Time_Stamp_Mismatch): use CRC_Match for comparison.
36934 (Set_Source_Table): idem.
36937 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
36938 instead of simple checksum.
36939 (CRC_Match): new function.
36940 (CRC_Error): new constant.
36942 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
36943 a CRC now and not a simple checksum. A CRC uses lower-case hex
36944 letters, fixes ambiguity in parsing.
36946 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
36947 is what this variable will store.
36949 * bcheck.adb: Change reference to chechsum in comments by CRC.
36950 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
36951 rename All_Checksum_Match to All_CRC_Match. Change due to API
36952 renaming since now GNAT does not use a simple checksum but a
36953 CRC using GNAT.CRC32.
36955 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
36956 now and not anymore a simple checksum.
36958 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
36961 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
36964 (Restore_Scan_State): rename Checksum to CRC.

36969 (Checksum): rename to CRC.
36970 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
36972 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
36973 GNAT.CRC32). Update copyright notice.
36975 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
36976 GNAT.CRC32). Update copyright notice.
36979 (Accumulate_Checksum): removed.
36980 (Update): new procedure. Add a wide-character into the CRC.
36983 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
36984 (Load_File): fix initialization of S (change Source_Checksum to
36987 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
36988 Source_CRC in S initialization.
36990 * sinput.adb (Source_Checksum): renamed to Source_CRC.
36992 * sinput.ads (Source_Checksum): renamed to Source_CRC.
36993 Update comments for the CRC.
36995 * types.adb (Hex): Use lowercase for the letter part.
36997 * types.ads (Get_Hex_String): Returns the hexadecimal representation
36998 for a word. This is currently used only for CRC. In previous version,
36999 the checksum was using a representation with all letter being
37000 upper-case. With the new implementation (using CRC) we do not remove
37001 the 32th bit of the CRC, so we can have an upper-case starting letter
37002 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
37003 It is ambigous since the CRC was optional and could be followed by
37004 options like EB, EE. So now this routines uses lower-case letter for
37005 the hexadecimal representation. Strange enough only lower case letters
37006 where checked in Scan_ALI (even if this was not a possible case).
37008 * gnatvsn.ads (Library_Version): changed to 3.15a.
37010 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
37013 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
37016 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
37017 Add 2001 to copyright notice
37018 (Accumulate_Checksum): Modify to use System.CRC32.
37020 * ali-util.ads: Redo changes of previous revision to continue to use
37021 the word Checksum. Add 2001 to copyright notice.
37023 * ali.adb: Undo some of previous changes, not needed.
37024 Keep the change for lower case letters in the checksum.
37026 * ali.ads: Undo previous change not needed.
37028 * bcheck.adb: Undo most of previous change, not needed.
37029 But do use Checksums_Match for checksum comparison.
37031 * gnatls.adb: Undo most of previous change, not needed.
37032 But do use Checksums_Match for comparing checksums.
37034 * lib-load.adb: Undo previous change, not needed.
37036 * lib-writ.adb: Undo previous change, not needed.
37038 * lib-writ.ads: Document that checksums use lower case,
37039 not upper case letters.

37043 * scans.ads: Undo previous change, not needed.
37045 * scn-nlit.adb: Undo previous changes, not needed.
37047 * scn-slit.adb: Undo previous change, not needed. Fix header format.

37052 Remove other changes of previous revision.
37054 * sinput-p.adb: Undo previous change, not needed.
37056 * sinput.adb: Undo previous change, not needed.
37058 * sinput-l.adb: Undo previous change, not needed.
37060 * sinput.ads: Undo previous change, not needed. Keep only comment
37061 on new checksum algorithm
37063 * Makefile.in: Add s-crc32 as needed, remove g-crc32.
37064 Also remove a-tags and a-stream from GNAT sources.
37066 * ali.adb (Scan_ALI): fix typo introduce in latest check-in.
37068 * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
