1549 a function can return a limited view of a type declared
1550 elsewhere. In that case the function cannot be frozen at the end
1551 of its enclosing package. If its first use is in a different unit,
1552 it cannot be frozen there, but if the call is legal the full view
1553 of the return type is available and the subprogram can now be
1554 frozen. However the freeze node cannot be inserted at the point
1555 of call, but rather must go in the package holding the function,
1556 so that the backend can process it in the proper context.

1613 * checks.adb (Apply_Scalar_Range_Check): Make sure we handle
1614 case of OUT and IN OUT parameter correctly (where Source_Typ is
1615 set), we were missing one case where a check must be applied.

1619 * sem_ch8.adb (Build_Class_Wide_Wrapper): Update the comment on
1620 the generated code. Instead of hiding the renaming and using the
1621 wrapper as the proper association, have the subprogram renaming

4316 Exception_Information is used to produce useful debugging
4317 information for the programmer. However, it was also used to
4318 implement the stream attributes for type Exception_Occurrence. The
4319 latter requires a stable and portable interface, which meant
4320 that we couldn't include a symbolic traceback. A separate set of
4321 routines was used to provide symbolic tracebacks under program
4322 control (i.e. not automatically). The goal of this ticket is
4323 to provide such automatic tracebacks, so the change here is to
4324 split the two functionalities: Exception_Information gives the
4325 maximally useful information for debugging (i.e. it now includes
4326 a symbolic traceback when a decorator is set, and it can be
4327 improved freely in the future without disturbing streaming).
4328 Untailored_Exception_Information always uses hexadecimal addresses
4329 in the traceback, has a stable and portable output, and is now

4353 Finalize procedures for this type.
4354 (Finalize): When finalizing a reference_preserving_key, verify
4355 that the key of the new value is equivalent to the key of the
4356 original element, raise Program_Error otherwise.

4372 GNAT.Traceback.Symbolic and GNAT.Exception_Traces into the System
4373 hierarchy (System.Traceback.Symbolic and System.Exception_Traces), so

4517 for example, in s-interr.adb, when Interrupt_Manager does "new

4563 the call returns an unconstrained type: in this case there is
4564 already a transient scope, and we should not establish a new one.

4566 True, also insert cleanup actions in the tree.
4567 (Wrap_Transient_Declaration): Call Insert_Actions_In_Scope_Around

4627 * sem_attr.adb: Minor reformatting.
4629 2014-07-30 Pat Rogers <rogers@adacore.com>
4631 * gnat_rm.texi: Corrected minor wording error in description
4632 of No_Exception_Registration.
4634 2014-07-30 Yannick Moy <moy@adacore.com>
4636 * einfo.ads, einfo.adb: New flag Is_Inlined_Always for use in GNATprove
4637 mode. Realphabetize two subprograms.

4640 (Check_And_Build_Body_To_Inline): Use Is_Inlined_Always in GNATprove
4642 (Expand_Inline_Call): Use Is_Inlined_Always in GNATprove mode.
4643 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not use
4644 Is_Inline in GNATprove mode.
4645 (Analyze_Subprogram_Specification):
4646 Set Is_Inlined_Always at subprogram entity creation.

4672 specified first subtype.
4674 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4676 * inline.adb (Expand_Inlined_Call): Use a renaming declaration
4677 to capture the value of actuals of a limited type rather than
4678 an object declaration, to prevent spurious errors when analyzing
4681 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4683 * sem_ch4.adb (Analyze_Type_Conversion): Treat an inlined body
4684 as an instance, and inhibit semantic checks on already analyzed
4685 code to prevent spurious errors.
4687 2014-07-30 Arnaud Charlet <charlet@adacore.com>
4689 * a-exctra.ads ("="): New function, to restore compatibility.

4698 * gnat_ugn.texi: Minor correction to description of -gnatw.K.
4700 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4702 * sem_util.adb (Wrong_Type): Disable some checks equally within
4703 instances and within inlined bodies, to suppress spurious type
4704 errors on already analyzed code.
4705 * sem_aggr.adb (Check_Expr_OK_In_Limited_Aggregate): Expression
4706 is legal in an inlined body, juts as it is in an instance body.
4708 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4710 * sem_res.adb (Resolve_Unchecked_Conversion): Within an inlined
4711 body the operand of an unchecked conversion may be a literal, in
4712 which case its type is the target type of the conversion. This
4713 is in contrast to conversions in other contexts, where the
4714 operand cannot be a literal and must be resolvable independent
4717 2014-07-30 Pierre-Marie Derodat <derodat@adacore.com>
4719 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Create a
4720 mere scalar constant instead of a reference for a renaming of

4733 & code reorganization.
4735 2014-07-30 Bob Duff <duff@adacore.com>
4737 * s-tassta.adb, sem_util.ads: Minor reformatting.
4739 2014-07-30 Yannick Moy <moy@adacore.com>
4741 * inline.adb (Build_Body_To_Inline): Detect when
4742 subprogram has multiple returns, or not a single last return
4743 statement, in GNATprove mode.
4744 (Cannot_Inline): Simplify logic to handle case of GNATprove
4747 2014-07-30 Ed Schonberg <schonberg@adacore.com>

4753 * s-tasuti.ads, s-tasuti.adb (Make_Independent): Change this
4754 from a procedure to a function, so that it can more easily be
4755 called before the "begin" of a task.
4756 * s-taasde.ads (Delay_Block): Make this type immutably limited,
4757 so we can use a build-in-place function call to initialize
4758 Timer_Queue in the body.
4759 * a-rttiev.adb, s-asthan-vms-alpha.adb, s-asthan-vms-ia64.adb,
4760 * s-interr.adb, s-interr-hwint.adb, s-interr-sigaction.adb,
4761 * s-interr-vms.adb, s-taasde.adb: Each independent task now calls
4762 Make_Independent before reaching its "begin", to avoid race
4763 conditions. This causes the activating task to wait until after
4764 Make_Independent is complete before proceeding. In addition,
4765 we initialize data structures used by independent tasks before
4766 activating those tasks, to avoid possible use of uninitialized data.
4767 * s-interr.ads, s-intman.ads, s-taspri-posix.ads, s-tasdeb.ads:
4768 Minor comment fixes.
4770 2014-07-30 Bob Duff <duff@adacore.com>
4772 * a-exctra.ads, s-traent-vms.ads, s-traent.ads (Tracebacks_Array): Move
4773 the declaration of Tracebacks_Array from Ada.Exceptions.Traceback to
4774 System.Traceback_Entries (s-traent.ads and s-traent-vms.ads). Add
4775 subtypes renaming Tracebacks_Array in Ada.Exceptions.Traceback.
4776 * g-debpoo.adb: Refer to Tracebacks_Array in its new home.
4778 2014-07-30 Arnaud Charlet <charlet@adacore.com>

4784 * einfo.ads (Is_Inlined): Document new use in GNATprove mode.
4785 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Add comments
4786 to explain rationale for inlining or not in GNATprove mode.
4787 (Expand_Inlined_Call): In GNATprove mode, set Is_Inlined flag
4788 to False when inlining is not possible.
4789 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Set Is_Inlined
4790 flag to indicate that subprogram is fully inlined. To be reversed
4791 if inlining problem is found.
4792 * sem_res.adb (Resolve_Call): Set Is_Inlined flag to False when
4793 call in potentially unevaluated context.
4795 2014-07-30 Jose Ruiz <ruiz@adacore.com>
4797 * s-tarest.adb, s-tarest.ads: Fix comments.
4799 2014-07-30 Robert Dewar <dewar@adacore.com>
4801 * exp_attr.adb, checks.adb, sem_util.adb, sem_util.ads, sem_attr.adb:
4802 Change No_Scalar_Parts predicate to Scalar_Part_Present and
4803 invert sense of test. This avoids the "not No_xxx" situation
4804 which is always ugly.
4806 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4808 * inline.adb (Expand_Inlined_Call): When generating code for
4809 an internal subprogram the expansion uses the location of the
4810 call, so that gdb can skip over it. In GNATprove mode we want to
4811 preserve slocs of original subprogram when expanding an inlined
4812 call, to obtain better warnings, even though subprogram appears
4813 not to come from source if it is the inlining of a subprogram
4814 body without a previous spec.
4816 2014-07-30 Eric Botcazou <ebotcazou@adacore.com>
4818 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Reject array
4819 types with atomic components.

4823 * Make-generated.in: Remove now unnecessary targets after s-oscons
4826 2014-07-30 Yannick Moy <moy@adacore.com>
4828 * sem_res.adb (Resolve_Call): Use ultimate alias
4829 of callee when available.
4831 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4833 * sem_ch6.adb (Analyze_Expression_Function): To check whether
4834 an expression function is a completion, use the specification of
4835 the previous declaration, not its entity, which may be internally
4836 generated in an inlined context.
4838 2014-07-30 Doug Rupp <rupp@adacore.com>
4840 * adaint.c (__gnat_tmp_name) [__ANDROID__]: Default to putting
4841 temp files in /cache directory unless overridden by TMPDIR.
4843 2014-07-30 Jose Ruiz <ruiz@adacore.com>
4845 * s-tassta.adb, s-tarest.adb (Initialize, Create_Task,
4846 Create_Restricted_Task): Remove redundant check. Number_Of_CPUs returns
4847 type CPU, so it can never be greater than CPU_Range'Last.
4849 2014-07-30 Bob Duff <duff@adacore.com>
4851 * s-taskin.ads: Minor comment fix.
4853 2014-07-30 Thomas Quinot <quinot@adacore.com>

4870 no longer supported.
4872 2014-07-30 Bob Duff <duff@adacore.com>
4874 * exp_ch6.adb (Add_Task_Actuals_To_Build_In_Place_Call): New
4875 parameter Chain to be used in the allocator case.
4876 (Make_Build_In_Place_Call_In_Allocator): If the allocated object
4877 has tasks, wrap the code in a block that will activate them,
4878 including the usual finalization code to kill them off in case
4879 of exception or abort.
4881 2014-07-30 Robert Dewar <dewar@adacore.com>
4883 * treepr.adb, treepr.ads; Reorganize documentation for new pp routines
4884 Remove renamings (don't work for gdb).

4907 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4909 * sem_ch6.adb (Body_Has_Contract): New predicate to determine
4910 when a subprogram body without a previous spec cannot be inlined
4911 in GNATprove mode, because it includes aspects or pragmas that
4912 generate a SPARK contract clause.
4913 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): A subprogram
4914 instance cannot be inlined.

4955 entity is created at this point, ensure that the name of the

4967 (Check_Component_Reference): Removed.
4968 (Resolve_Attribute): Remove the return statement and ??? comment

5037 * sem_ch6.adb (Hanalyze_Subprogram_Body_Helper): In GNATprove
5038 mode, subprogram bodies without a previous declaration are also
5039 candidates for front-end inlining.
5041 2014-07-30 Hristian Kirtchev <kirtchev@adacore.com>
5043 * aspects.ads Aspects Async_Readers, Async_Writers,

5215 clause for the object and the expression is an aggregate, defer
5216 resolution and expansion of the aggregate until the freeze point
5218 * sem_aggr.adb (Resolve_Aggregate): An others_clause is legal if
5219 the parent node is an N_Reference generated during expansion.
5221 2014-07-29 Vincent Celier <celier@adacore.com>

5338 * sem_ch3.adb (Constrain_Corresponding_Record): For the case
5339 of the subtype created for a record component, do not mark
5340 the subtype as frozen. For one thing, this is anomalous (in
5341 particular, the base type might not itself be frozen yet);
5342 furthermore, proper freezing of the subtype must happen in any
5343 case. So, we just mark the subtype as requiring delayed freezing
5344 (and we'll actually freeze it when generating the init_proc of
5345 the enclosing record).
5346 Also change the name of the constrained record subtype (append a
5347 'C' so that it is clearly different from the unconstrained record
5348 type, "related_idV") to make debugging easier.
5349 (Process_Full_View): When creating a full subtype for a pending

5372 parameter of a null-excluding access type, there is access check
5373 on entry, so set Suppress_Assignment_Checks on generated statement
5374 that assigns actual to parameter block.
5375 * sinfo.ads: Document additional use of Suppress_Assignment_Checks.
5377 2014-07-29 Robert Dewar <dewar@adacore.com>

5471 create elaboration flag.
5472 * exp_util.adb (Set_Elaboration_Flag): If the subprogram body
5473 is a completion of a declaration in the same declarative part,
5474 and the subprogram has had its address taken, add elaboration
5475 check inside the subprogram body, to detect elaboration errors
5476 that may occur through indirect calls.

11511 time from Vulnerable_Complete_Master "for convenience" (i.e. to
11512 kill off tasks waiting at terminate alternatives), aborting
11513 indirect dependents is wrong, because it causes some unrelated
11514 tasks to get aborted.

13261 the source location of the original, to prevent spurious errors
13262 when compiling with style checks if the declaration involves
13263 more than one entity.
