77 Container.Last = Last. That test isn't even needed, because the
78 loop will go around zero times in that case, so deleted that
79 test rather than fixing it.

107 work with 'Unrestricted_Access when the result is returned from

343 affinity. The new Create (which takes a set) now does all the
344 work; the old Create (which takes a range) now just calls the

3136 of the return type is available and the subprogram can now be
3137 frozen. However the freeze node cannot be inserted at the point
3138 of call, but rather must go in the package holding the function,
3139 so that the backend can process it in the proper context.

5899 Exception_Information is used to produce useful debugging
5900 information for the programmer. However, it was also used to
5901 implement the stream attributes for type Exception_Occurrence. The
5902 latter requires a stable and portable interface, which meant
5903 that we couldn't include a symbolic traceback. A separate set of
5904 routines was used to provide symbolic tracebacks under program
5905 control (i.e. not automatically). The goal of this ticket is
5906 to provide such automatic tracebacks, so the change here is to
5907 split the two functionalities: Exception_Information gives the
5908 maximally useful information for debugging (i.e. it now includes
5909 a symbolic traceback when a decorator is set, and it can be
5910 improved freely in the future without disturbing streaming).
5911 Untailored_Exception_Information always uses hexadecimal addresses
5912 in the traceback, has a stable and portable output, and is now

6084 2014-07-30 Javier Miranda <miranda@adacore.com>
6086 * Makefile.rtl, gnat_rm.texi, i-cpp.adb, i-cpp.ads, impunit.adb,
6087 rtsfind.ads: Remove references to package Interfaces.CPP since this
6088 package is no longer needed.
6090 2014-07-30 Bob Duff <duff@adacore.com>
6092 * s-taasde.adb (Timer_Queue): Don't use a
6093 build-in-place function call to initialize the Timer_Queue.
6094 * s-traent.adb, s-traent.ads, s-traent-vms.adb, s-traent-vms.ads:
6095 Turn off polling in these units, because otherwise we get
6096 elaboration circularities with Ada.Exceptions when the -gnatP
6098 * s-tassta.adb (Create_Task): Make sure independent tasks
6099 are created with Parent = Environment_Task. This was not true,
6100 for example, in s-interr.adb, when Interrupt_Manager does "new
6101 Server_Task"; the Server_Task had Parent = Interrupt_Manager,
6102 which is wrong because the master is determined by the access
6103 type, which is at library level.
6104 * s-tasuti.adb (Make_Independent): Avoid setting Parent; it is
6105 now set correctly by Create_Task.
6106 (Make_Passive): Remove the workaround for the race condition in
6108 * frontend.adb (Frontend): Revert to previous method of detecting
6109 temporary configuration pragma files, recognizing such files by
6110 ".tmp" in the name. This is more general than detecting pragmas
6111 Source_File_Name_Project, because it allows any tool to use
6112 this naming convention, no matter the content of the file.
6113 * gnat_ugn.texi: Document this naming convention.
6115 2014-07-30 Robert Dewar <dewar@adacore.com>

6124 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6126 * sem_ch5.adb: Improve error recovery.
6127 * inline.adb (Build_Body_To_Inline): Set Full_Analysis to false
6128 before analyzing the body, so that in GNATprove mode there is
6129 no light expansion. Whatever expansion is required by SPARK will
6130 be performed when analysing the inlined code.
6132 2014-07-30 Bob Duff <duff@adacore.com>
6134 * s-tataat.adb, s-tataat.ads, a-tasatt.adb: Minor comment fixes.

6143 * sem.ads (Scope_Table_Entry): New component Locked_Shared_Objects.
6144 * sem_ch8.adb (Push_Scope): Initialize Locked_Shared_Objects.
6145 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Handle the case where
6146 the call returns an unconstrained type: in this case there is
6147 already a transient scope, and we should not establish a new one.
6148 * exp_ch7.adb (Insert_Actions_In_Scope_Around): New formal Clean. If
6149 True, also insert cleanup actions in the tree.
6150 (Wrap_Transient_Declaration): Call Insert_Actions_In_Scope_Around
6151 with Clean set True.
6153 2014-07-30 Arnaud Charlet <charlet@adacore.com>
6155 * s-taskin.ads (Direct_Index, Direct_Index_Range,
6156 Direct_Attribute_Element, Direct_Attribute_Array,
6157 Direct_Index_Vector, Direct_Attributes, Is_Defined,
6158 Indirect_Attributes): Removed. (Atomic_Address,
6159 Attribute_Array, Attributes): New.
6160 * s-tasini.ads, s-tasini.adb (Proc_T, Initialize_Attributes,
6161 Finalize_Attributes_Link, Initialize_Attributes_Link): Removed.
6162 (Finalize_Attributes): Reimplement.
6163 * s-tassta.adb (Create_Task): Remove call to
6164 Initialize_Attributes_Link (Free_Task, Vulnerable_Free_Task):
6165 Replace Finalize_Attributes_Link by Finalize_Attributes.
6166 * a-tasatt.ads, a-tasatt.adb, s-tataat.ads, s-tataat.adb:
6167 Reimplement from scratch, using a simpler and more efficient
6169 * s-tporft.adb (Register_Foreign_Thread): Remove now obsolete comment.
6170 * s-parame.ads, s-parame-hpux.ads,
6171 * s-parame-vms-alpha.ads, s-parame-vms-ia64.ads,

6173 Default_Attribute_Count.
6175 2014-07-30 Olivier Hainque <hainque@adacore.com>
6177 * vxworks-ppc-link.spec: New file. Extra link
6178 instructions for ppc-vxworks.
6179 * vxworks-crtbe-link.spec: Likewise, for ZCX related support.
6180 * system-vxworks-ppc.ads: Adjust linker options to use spec files.
6181 * system-vxworks-arm.ads: Likewise.
6182 * gcc-interface/Makefile.in: Enable .spec files.
6184 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6186 * sem_aggr.adb: Minor comment reformatting.
6188 2014-07-30 Robert Dewar <dewar@adacore.com>
6190 * sem_util.ads, sem_util.adb (Is_Junk_Name): Removed.
6191 * sem_warn.adb (Has_Junk_Name): New function
6192 (Check_References): Use Has_Junk_Name to delete junk warnings

6194 (Warn_On_Unreferenced_Entity): ditto.
6195 (Warn_On_Useless_Assignment): ditto.
6197 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6199 * checks.adb (Insert_Valid_Check): Do not check for the packed
6200 array type of a prefix that is an access type.
6202 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6204 * sem_attr.adb (Eval_Attribute): Evaluate the GNAT attribute
6205 Unconstrained_Array even if prefix is not frozen yet, as can
6206 occur with a private subtype used as a generic actual.
6208 2014-07-30 Gary Dismukes <dismukes@adacore.com>
6210 * sem_attr.adb: Minor reformatting.
6212 2014-07-30 Pat Rogers <rogers@adacore.com>
6214 * gnat_rm.texi: Corrected minor wording error in description
6215 of No_Exception_Registration.
6217 2014-07-30 Yannick Moy <moy@adacore.com>
6219 * einfo.ads, einfo.adb: New flag Is_Inlined_Always for use in GNATprove
6220 mode. Realphabetize two subprograms.
6221 * inline.adb (Cannot_Inline): Use Is_Inlined_Always in GNATprove mode.
6222 (Can_Be_Inlined_In_GNATprove_Mode): Adapt to possible Empty Body_Id.
6223 (Check_And_Build_Body_To_Inline): Use Is_Inlined_Always in GNATprove
6225 (Expand_Inline_Call): Use Is_Inlined_Always in GNATprove mode.
6226 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not use
6227 Is_Inline in GNATprove mode.
6228 (Analyze_Subprogram_Specification):
6229 Set Is_Inlined_Always at subprogram entity creation.
6230 * sem_res.adb (Resolve_Call): Do not deal with inlining during
6231 pre-analysis. Issue warning on call to possibly inlined
6232 subprogram when body not seen.
6234 2014-07-30 Yannick Moy <moy@adacore.com>
6236 * lib-xref.adb (Generate_Reference): Add special
6237 case for compiler-generated formals in GNATprove mode.
6239 2014-07-30 Yannick Moy <moy@adacore.com>
6241 * sem_ch6.adb: Add comments.
6243 2014-07-30 Thomas Quinot <quinot@adacore.com>

6247 2014-07-30 Robert Dewar <dewar@adacore.com>
6249 * sem_aggr.adb, sem_res.adb: Minor reformatting.
6251 2014-07-30 Thomas Quinot <quinot@adacore.com>
6253 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
6254 Bit_Order): Set Reverse_Bit_Order on the base type of the
6255 specified first subtype.
6257 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6259 * inline.adb (Expand_Inlined_Call): Use a renaming declaration
6260 to capture the value of actuals of a limited type rather than
6261 an object declaration, to prevent spurious errors when analyzing
6264 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6266 * sem_ch4.adb (Analyze_Type_Conversion): Treat an inlined body
6267 as an instance, and inhibit semantic checks on already analyzed
6268 code to prevent spurious errors.
6270 2014-07-30 Arnaud Charlet <charlet@adacore.com>
6272 * a-exctra.ads ("="): New function, to restore compatibility.
6274 2014-07-30 Pascal Obry <obry@adacore.com>

6277 routine to use the OS dst setting.
6279 2014-07-30 Pat Rogers <rogers@adacore.com>
6281 * gnat_ugn.texi: Minor correction to description of -gnatw.K.
6283 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6285 * sem_util.adb (Wrong_Type): Disable some checks equally within
6286 instances and within inlined bodies, to suppress spurious type
6287 errors on already analyzed code.
6288 * sem_aggr.adb (Check_Expr_OK_In_Limited_Aggregate): Expression
6289 is legal in an inlined body, juts as it is in an instance body.
6291 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6293 * sem_res.adb (Resolve_Unchecked_Conversion): Within an inlined
6294 body the operand of an unchecked conversion may be a literal, in
6295 which case its type is the target type of the conversion. This
6296 is in contrast to conversions in other contexts, where the
6297 operand cannot be a literal and must be resolvable independent
6300 2014-07-30 Pierre-Marie Derodat <derodat@adacore.com>
6302 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Create a
6303 mere scalar constant instead of a reference for a renaming of

6308 2014-07-30 Robert Dewar <dewar@adacore.com>
6310 * s-tasuti.adb, s-tasuti.ads, einfo.ads, sem_prag.adb, s-taasde.adb,

6315 s-interr-sigaction.adb, s-os_lib.adb, s-fileio.adb: Minor reformatting
6316 & code reorganization.
6318 2014-07-30 Bob Duff <duff@adacore.com>
6320 * s-tassta.adb, sem_util.ads: Minor reformatting.
6322 2014-07-30 Yannick Moy <moy@adacore.com>
6324 * inline.adb (Build_Body_To_Inline): Detect when
6325 subprogram has multiple returns, or not a single last return
6326 statement, in GNATprove mode.
6327 (Cannot_Inline): Simplify logic to handle case of GNATprove
6330 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6332 * sem_ch6.adb: Stubs are not subject to inlining.
6334 2014-07-30 Bob Duff <duff@adacore.com>
6336 * s-tasuti.ads, s-tasuti.adb (Make_Independent): Change this
6337 from a procedure to a function, so that it can more easily be
6338 called before the "begin" of a task.
6339 * s-taasde.ads (Delay_Block): Make this type immutably limited,
6340 so we can use a build-in-place function call to initialize
6341 Timer_Queue in the body.
6342 * a-rttiev.adb, s-asthan-vms-alpha.adb, s-asthan-vms-ia64.adb,
6343 * s-interr.adb, s-interr-hwint.adb, s-interr-sigaction.adb,
6344 * s-interr-vms.adb, s-taasde.adb: Each independent task now calls
6345 Make_Independent before reaching its "begin", to avoid race
6346 conditions. This causes the activating task to wait until after
6347 Make_Independent is complete before proceeding. In addition,
6348 we initialize data structures used by independent tasks before
6349 activating those tasks, to avoid possible use of uninitialized data.
6350 * s-interr.ads, s-intman.ads, s-taspri-posix.ads, s-tasdeb.ads:
6351 Minor comment fixes.
6353 2014-07-30 Bob Duff <duff@adacore.com>
6355 * a-exctra.ads, s-traent-vms.ads, s-traent.ads (Tracebacks_Array): Move
6356 the declaration of Tracebacks_Array from Ada.Exceptions.Traceback to
6357 System.Traceback_Entries (s-traent.ads and s-traent-vms.ads). Add
6358 subtypes renaming Tracebacks_Array in Ada.Exceptions.Traceback.
6359 * g-debpoo.adb: Refer to Tracebacks_Array in its new home.
6361 2014-07-30 Arnaud Charlet <charlet@adacore.com>
6363 * a-tasatt.adb: Remove old comments.
6365 2014-07-30 Yannick Moy <moy@adacore.com>
6367 * einfo.ads (Is_Inlined): Document new use in GNATprove mode.
6368 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Add comments
6369 to explain rationale for inlining or not in GNATprove mode.
6370 (Expand_Inlined_Call): In GNATprove mode, set Is_Inlined flag
6371 to False when inlining is not possible.
6372 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Set Is_Inlined
6373 flag to indicate that subprogram is fully inlined. To be reversed
6374 if inlining problem is found.
6375 * sem_res.adb (Resolve_Call): Set Is_Inlined flag to False when
6376 call in potentially unevaluated context.
6378 2014-07-30 Jose Ruiz <ruiz@adacore.com>
6380 * s-tarest.adb, s-tarest.ads: Fix comments.
6382 2014-07-30 Robert Dewar <dewar@adacore.com>
6384 * exp_attr.adb, checks.adb, sem_util.adb, sem_util.ads, sem_attr.adb:
6385 Change No_Scalar_Parts predicate to Scalar_Part_Present and
6386 invert sense of test. This avoids the "not No_xxx" situation
6387 which is always ugly.
6389 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6391 * inline.adb (Expand_Inlined_Call): When generating code for
6392 an internal subprogram the expansion uses the location of the
6393 call, so that gdb can skip over it. In GNATprove mode we want to
6394 preserve slocs of original subprogram when expanding an inlined
6395 call, to obtain better warnings, even though subprogram appears
6396 not to come from source if it is the inlining of a subprogram
6397 body without a previous spec.
6399 2014-07-30 Eric Botcazou <ebotcazou@adacore.com>
6401 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Reject array
6402 types with atomic components.
6404 2014-07-30 Thomas Quinot <quinot@adacore.com>
6406 * Make-generated.in: Remove now unnecessary targets after s-oscons
6409 2014-07-30 Yannick Moy <moy@adacore.com>
6411 * sem_res.adb (Resolve_Call): Use ultimate alias
6412 of callee when available.
6414 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6416 * sem_ch6.adb (Analyze_Expression_Function): To check whether
6417 an expression function is a completion, use the specification of
6418 the previous declaration, not its entity, which may be internally
6419 generated in an inlined context.
6421 2014-07-30 Doug Rupp <rupp@adacore.com>
6423 * adaint.c (__gnat_tmp_name) [__ANDROID__]: Default to putting
6424 temp files in /cache directory unless overridden by TMPDIR.
6426 2014-07-30 Jose Ruiz <ruiz@adacore.com>
6428 * s-tassta.adb, s-tarest.adb (Initialize, Create_Task,
6429 Create_Restricted_Task): Remove redundant check. Number_Of_CPUs returns
6430 type CPU, so it can never be greater than CPU_Range'Last.
6432 2014-07-30 Bob Duff <duff@adacore.com>
6434 * s-taskin.ads: Minor comment fix.
6436 2014-07-30 Thomas Quinot <quinot@adacore.com>

6450 * Make-generated.in: Remove generation of s-oscons.ads, only
6451 generate the xoscons utility, in runtime-agnostic rules.
6452 * gcc-interface/Makefile.in: Clean up rules. Remove VMS parts,
6453 no longer supported.
6455 2014-07-30 Bob Duff <duff@adacore.com>
6457 * exp_ch6.adb (Add_Task_Actuals_To_Build_In_Place_Call): New
6458 parameter Chain to be used in the allocator case.
6459 (Make_Build_In_Place_Call_In_Allocator): If the allocated object
6460 has tasks, wrap the code in a block that will activate them,
6461 including the usual finalization code to kill them off in case
6462 of exception or abort.
6464 2014-07-30 Robert Dewar <dewar@adacore.com>
6466 * treepr.adb, treepr.ads; Reorganize documentation for new pp routines
6467 Remove renamings (don't work for gdb).
6468 (par): New synonym for p (avoid gdb ambiguities).
6469 * inline.adb, sem_ch6.adb, sem_ch13.adb: Minor reformatting.
6471 2014-07-30 Bob Duff <duff@adacore.com>
6473 * exp_ch9.ads, sem_prag.adb, exp_ch4.adb, sem_ch13.adb: Minor comment
6475 * treepr.ads, treepr.adb (ppp): Make this debugging routine
6476 accept any type covered by Union_Id.

6488 of predicate aspect on entity other than a type.
6490 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6492 * sem_ch6.adb (Body_Has_Contract): New predicate to determine
6493 when a subprogram body without a previous spec cannot be inlined
6494 in GNATprove mode, because it includes aspects or pragmas that
6495 generate a SPARK contract clause.
6496 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): A subprogram
6497 instance cannot be inlined.
6499 2014-07-30 Robert Dewar <dewar@adacore.com>

6523 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6525 * par-ch4.adb (Is_Parameterless_Attribute): 'Result is a
6526 parameterless attribute, and a postondition can mention an
6527 indexed component or a slice whose prefix is an attribute
6530 2014-07-30 Robert Dewar <dewar@adacore.com>
6532 * sprint.adb (Sprint_Node_Actual, case Object_Declaration):
6533 Avoid bomb when printing package Standard.
6535 2014-07-30 Ed Schonberg <schonberg@adacore.com>
6537 * sem_elab.adb (Check_Internal_Call_Continue): If an elaboration
6538 entity is created at this point, ensure that the name of the
6539 flag is unique, because the subprogram may be overloaded and
6540 other homonyms may also have elaboration flags created on the fly.
6542 2014-07-30 Hristian Kirtchev <kirtchev@adacore.com>
6544 * sem_attr.adb (Analyze_Array_Component_Update): New routine.
6545 (Analyze_Attribute): Major cleanup of attribute

6550 (Check_Component_Reference): Removed.
6551 (Resolve_Attribute): Remove the return statement and ??? comment
6552 following the processing for attribute 'Update. As a result,
6553 the attribute now freezes its prefix.

6557 * exp_ch4.adb (Apply_Accessibility_Check): Do
6558 not call Base_Address() in VM targets.

6921 * sem_ch3.adb (Constrain_Corresponding_Record): For the case
6922 of the subtype created for a record component, do not mark
6923 the subtype as frozen. For one thing, this is anomalous (in
6924 particular, the base type might not itself be frozen yet);
6925 furthermore, proper freezing of the subtype must happen in any
6926 case. So, we just mark the subtype as requiring delayed freezing
6927 (and we'll actually freeze it when generating the init_proc of
6928 the enclosing record).
6929 Also change the name of the constrained record subtype (append a
6930 'C' so that it is clearly different from the unconstrained record
6931 type, "related_idV") to make debugging easier.
6932 (Process_Full_View): When creating a full subtype for a pending

7056 is a completion of a declaration in the same declarative part,
7057 and the subprogram has had its address taken, add elaboration
7058 check inside the subprogram body, to detect elaboration errors
7059 that may occur through indirect calls.

13089 * s-taskin.ads: Minor comment fix.
13090 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
13091 just direct dependents. If this is actually an abort, each task

13094 time from Vulnerable_Complete_Master "for convenience" (i.e. to
13095 kill off tasks waiting at terminate alternatives), aborting
13096 indirect dependents is wrong, because it causes some unrelated
13097 tasks to get aborted.

15860 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Robustify tests
15861 for aliased objects with an unconstrained nominal subtype.
15862 * gcc-interface/trans.c (Call_to_gnu): Likewise.
15863 (gnat_to_gnu) <case N_Op_Not>: Robustify test for private type.
15864 <case N_Op_Minus>: Remove useless code.
15865 (Exception_Handler_to_gnu_zcx): Minor tweaks.
15867 2014-01-20 Eric Botcazou <ebotcazou@adacore.com>
15869 * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Record_Subtype>:
15870 Tidy up. For a subtype with discriminants and variant part, if a
15871 variant is statically selected and the fields all have a constant
15872 position, put them in order of increasing position. Likewise if
15873 no variant part but representation clause is present.
15874 * gcc-interface/utils.c (make_packable_type): Robustify.
15875 (maybe_pad_type): Use local variable and tidy up condition. If no
15876 alignment is specified, use the original one.
15877 (create_type_stub_decl): Minor tweak.
15878 (convert) <case VECTOR_CST>: Fix typo.
15879 <case CONSTRUCTOR>: Deal with padding types around the same type.
15880 Do not punt on missing fields.
15881 (unchecked_convert): Call finish_record_type to lay out the special
15882 record types made for conversions from/to problematic integer types.
15883 Bump the alignment of CONSTRUCTORs before converting them to a more
15886 2014-01-20 Eric Botcazou <ebotcazou@adacore.com>
15888 * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Component>: Remove
15889 obsolete code for type_annotate_only mode, simplify code and slightly
15890 improve wording of comments.
15892 2014-01-12 Eric Botcazou <ebotcazou@adacore.com>
15895 * gcc-interface/cuintp.c (build_cst_from_int): Use 32-bit integer type
15896 as intermediate type.
15897 (UI_To_gnu): Likewise.
15899 2014-01-03 Eric Botcazou <ebotcazou@adacore.com>
15901 * gnatvsn.ads (Current_Year): Bump to 2014.
15903 2014-01-02 Tobias Burnus <burnus@net-b.de>
