952 * freeze.adb (Late_Freeze_Subprogram): Following AI05-151,
953 a function can return a limited view of a type declared
954 elsewhere. In that case the function cannot be frozen at the end

956 it cannot be frozen there, but if the call is legal the full view
957 of the return type is available and the subprogram can now be
958 frozen. However the freeze node cannot be inserted at the point
959 of call, but rather must go in the package holding the function,
960 so that the backend can process it in the proper context.

1017 * checks.adb (Apply_Scalar_Range_Check): Make sure we handle
1018 case of OUT and IN OUT parameter correctly (where Source_Typ is
1019 set), we were missing one case where a check must be applied.

1023 * sem_ch8.adb (Build_Class_Wide_Wrapper): Update the comment on
1024 the generated code. Instead of hiding the renaming and using the

3529 to Insert_Actions_In_Scope_Around to account for parameter Manage_SS.
3530 (Wrap_Transient_Declaration): Remove local variable
3531 Uses_SS. Ensure that the secondary stack is marked and released

3720 Exception_Information is used to produce useful debugging
3721 information for the programmer. However, it was also used to
3722 implement the stream attributes for type Exception_Occurrence. The
3723 latter requires a stable and portable interface, which meant
3724 that we couldn't include a symbolic traceback. A separate set of
3725 routines was used to provide symbolic tracebacks under program
3726 control (i.e. not automatically). The goal of this ticket is
3727 to provide such automatic tracebacks, so the change here is to
3728 split the two functionalities: Exception_Information gives the
3729 maximally useful information for debugging (i.e. it now includes
3730 a symbolic traceback when a decorator is set, and it can be
3731 improved freely in the future without disturbing streaming).
3732 Untailored_Exception_Information always uses hexadecimal addresses
3733 in the traceback, has a stable and portable output, and is now

3754 * a-coorse.adb, a-coorse.ads (Generic_Keys): Add a

3757 Finalize procedures for this type.
3758 (Finalize): When finalizing a reference_preserving_key, verify
3759 that the key of the new value is equivalent to the key of the
3760 original element, raise Program_Error otherwise.

3776 GNAT.Traceback.Symbolic and GNAT.Exception_Traces into the System
3777 hierarchy (System.Traceback.Symbolic and System.Exception_Traces), so

3921 for example, in s-interr.adb, when Interrupt_Manager does "new

4021 array type of a prefix that is an access type.
4023 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4025 * sem_attr.adb (Eval_Attribute): Evaluate the GNAT attribute
4026 Unconstrained_Array even if prefix is not frozen yet, as can

4029 2014-07-30 Gary Dismukes <dismukes@adacore.com>
4031 * sem_attr.adb: Minor reformatting.
4033 2014-07-30 Pat Rogers <rogers@adacore.com>
4035 * gnat_rm.texi: Corrected minor wording error in description
4036 of No_Exception_Registration.
4038 2014-07-30 Yannick Moy <moy@adacore.com>
4040 * einfo.ads, einfo.adb: New flag Is_Inlined_Always for use in GNATprove
4041 mode. Realphabetize two subprograms.

4044 (Check_And_Build_Body_To_Inline): Use Is_Inlined_Always in GNATprove
4046 (Expand_Inline_Call): Use Is_Inlined_Always in GNATprove mode.
4047 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not use
4048 Is_Inline in GNATprove mode.
4049 (Analyze_Subprogram_Specification):
4050 Set Is_Inlined_Always at subprogram entity creation.

4076 specified first subtype.
4078 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4080 * inline.adb (Expand_Inlined_Call): Use a renaming declaration
4081 to capture the value of actuals of a limited type rather than
4082 an object declaration, to prevent spurious errors when analyzing
4085 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4087 * sem_ch4.adb (Analyze_Type_Conversion): Treat an inlined body
4088 as an instance, and inhibit semantic checks on already analyzed
4089 code to prevent spurious errors.
4091 2014-07-30 Arnaud Charlet <charlet@adacore.com>
4093 * a-exctra.ads ("="): New function, to restore compatibility.
4095 2014-07-30 Pascal Obry <obry@adacore.com>

4098 routine to use the OS dst setting.
4100 2014-07-30 Pat Rogers <rogers@adacore.com>
4102 * gnat_ugn.texi: Minor correction to description of -gnatw.K.
4104 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4106 * sem_util.adb (Wrong_Type): Disable some checks equally within
4107 instances and within inlined bodies, to suppress spurious type
4108 errors on already analyzed code.
4109 * sem_aggr.adb (Check_Expr_OK_In_Limited_Aggregate): Expression
4110 is legal in an inlined body, juts as it is in an instance body.
4112 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4114 * sem_res.adb (Resolve_Unchecked_Conversion): Within an inlined
4115 body the operand of an unchecked conversion may be a literal, in
4116 which case its type is the target type of the conversion. This
4117 is in contrast to conversions in other contexts, where the
4118 operand cannot be a literal and must be resolvable independent
4121 2014-07-30 Pierre-Marie Derodat <derodat@adacore.com>
4123 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Create a
4124 mere scalar constant instead of a reference for a renaming of

4136 s-interr-sigaction.adb, s-os_lib.adb, s-fileio.adb: Minor reformatting
4137 & code reorganization.
4139 2014-07-30 Bob Duff <duff@adacore.com>

4146 subprogram has multiple returns, or not a single last return
4147 statement, in GNATprove mode.
4148 (Cannot_Inline): Simplify logic to handle case of GNATprove
4151 2014-07-30 Ed Schonberg <schonberg@adacore.com>

4157 * s-tasuti.ads, s-tasuti.adb (Make_Independent): Change this
4158 from a procedure to a function, so that it can more easily be
4159 called before the "begin" of a task.
4160 * s-taasde.ads (Delay_Block): Make this type immutably limited,
4161 so we can use a build-in-place function call to initialize
4162 Timer_Queue in the body.
4163 * a-rttiev.adb, s-asthan-vms-alpha.adb, s-asthan-vms-ia64.adb,
4164 * s-interr.adb, s-interr-hwint.adb, s-interr-sigaction.adb,
4165 * s-interr-vms.adb, s-taasde.adb: Each independent task now calls
4166 Make_Independent before reaching its "begin", to avoid race
4167 conditions. This causes the activating task to wait until after
4168 Make_Independent is complete before proceeding. In addition,
4169 we initialize data structures used by independent tasks before
4170 activating those tasks, to avoid possible use of uninitialized data.
4171 * s-interr.ads, s-intman.ads, s-taspri-posix.ads, s-tasdeb.ads:
4172 Minor comment fixes.
4174 2014-07-30 Bob Duff <duff@adacore.com>
4176 * a-exctra.ads, s-traent-vms.ads, s-traent.ads (Tracebacks_Array): Move
4177 the declaration of Tracebacks_Array from Ada.Exceptions.Traceback to
4178 System.Traceback_Entries (s-traent.ads and s-traent-vms.ads). Add
4179 subtypes renaming Tracebacks_Array in Ada.Exceptions.Traceback.
4180 * g-debpoo.adb: Refer to Tracebacks_Array in its new home.
4182 2014-07-30 Arnaud Charlet <charlet@adacore.com>

4189 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Add comments
4190 to explain rationale for inlining or not in GNATprove mode.
4191 (Expand_Inlined_Call): In GNATprove mode, set Is_Inlined flag
4192 to False when inlining is not possible.
4193 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Set Is_Inlined
4194 flag to indicate that subprogram is fully inlined. To be reversed
4195 if inlining problem is found.
4196 * sem_res.adb (Resolve_Call): Set Is_Inlined flag to False when
4197 call in potentially unevaluated context.
4199 2014-07-30 Jose Ruiz <ruiz@adacore.com>
4201 * s-tarest.adb, s-tarest.ads: Fix comments.
4203 2014-07-30 Robert Dewar <dewar@adacore.com>
4205 * exp_attr.adb, checks.adb, sem_util.adb, sem_util.ads, sem_attr.adb:
4206 Change No_Scalar_Parts predicate to Scalar_Part_Present and
4207 invert sense of test. This avoids the "not No_xxx" situation
4208 which is always ugly.
4210 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4212 * inline.adb (Expand_Inlined_Call): When generating code for
4213 an internal subprogram the expansion uses the location of the
4214 call, so that gdb can skip over it. In GNATprove mode we want to
4215 preserve slocs of original subprogram when expanding an inlined
4216 call, to obtain better warnings, even though subprogram appears
4217 not to come from source if it is the inlining of a subprogram
4218 body without a previous spec.
4220 2014-07-30 Eric Botcazou <ebotcazou@adacore.com>
4222 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Reject array
4223 types with atomic components.

4227 * Make-generated.in: Remove now unnecessary targets after s-oscons
4230 2014-07-30 Yannick Moy <moy@adacore.com>
4232 * sem_res.adb (Resolve_Call): Use ultimate alias
4233 of callee when available.
4235 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4237 * sem_ch6.adb (Analyze_Expression_Function): To check whether
4238 an expression function is a completion, use the specification of
4239 the previous declaration, not its entity, which may be internally
4240 generated in an inlined context.
4242 2014-07-30 Doug Rupp <rupp@adacore.com>
4244 * adaint.c (__gnat_tmp_name) [__ANDROID__]: Default to putting
4245 temp files in /cache directory unless overridden by TMPDIR.
4247 2014-07-30 Jose Ruiz <ruiz@adacore.com>
4249 * s-tassta.adb, s-tarest.adb (Initialize, Create_Task,
4250 Create_Restricted_Task): Remove redundant check. Number_Of_CPUs returns
4251 type CPU, so it can never be greater than CPU_Range'Last.
4253 2014-07-30 Bob Duff <duff@adacore.com>
4255 * s-taskin.ads: Minor comment fix.
4257 2014-07-30 Thomas Quinot <quinot@adacore.com>

4274 no longer supported.
4276 2014-07-30 Bob Duff <duff@adacore.com>
4278 * exp_ch6.adb (Add_Task_Actuals_To_Build_In_Place_Call): New
4279 parameter Chain to be used in the allocator case.
4280 (Make_Build_In_Place_Call_In_Allocator): If the allocated object
4281 has tasks, wrap the code in a block that will activate them,
4282 including the usual finalization code to kill them off in case
4283 of exception or abort.
4285 2014-07-30 Robert Dewar <dewar@adacore.com>
4287 * treepr.adb, treepr.ads; Reorganize documentation for new pp routines
4288 Remove renamings (don't work for gdb).
4289 (par): New synonym for p (avoid gdb ambiguities).

4311 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4313 * sem_ch6.adb (Body_Has_Contract): New predicate to determine
4314 when a subprogram body without a previous spec cannot be inlined
4315 in GNATprove mode, because it includes aspects or pragmas that
4316 generate a SPARK contract clause.
4317 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): A subprogram
4318 instance cannot be inlined.

4346 * par-ch4.adb (Is_Parameterless_Attribute): 'Result is a
4347 parameterless attribute, and a postondition can mention an
4348 indexed component or a slice whose prefix is an attribute

4353 * sprint.adb (Sprint_Node_Actual, case Object_Declaration):
4354 Avoid bomb when printing package Standard.
4356 2014-07-30 Ed Schonberg <schonberg@adacore.com>
4358 * sem_elab.adb (Check_Internal_Call_Continue): If an elaboration
4359 entity is created at this point, ensure that the name of the

4371 (Check_Component_Reference): Removed.
4372 (Resolve_Attribute): Remove the return statement and ??? comment

4441 * sem_ch6.adb (Hanalyze_Subprogram_Body_Helper): In GNATprove
4442 mode, subprogram bodies without a previous declaration are also
4443 candidates for front-end inlining.
4445 2014-07-30 Hristian Kirtchev <kirtchev@adacore.com>
4447 * aspects.ads Aspects Async_Readers, Async_Writers,

4618 * sem_ch3.adb (Analyze_Object_Declaration): If there is an address
4619 clause for the object and the expression is an aggregate, defer
4620 resolution and expansion of the aggregate until the freeze point
4622 * sem_aggr.adb (Resolve_Aggregate): An others_clause is legal if
4623 the parent node is an N_Reference generated during expansion.
4625 2014-07-29 Vincent Celier <celier@adacore.com>
4627 * prj.adb (Add_To_Buffer): Effectively double the size of the buffer.

4633 * exp_ch6.adb (Expand_Actuals): Generate predicate test
4634 unconditionally for case of OUT or IN OUT actual (before this

4742 * sem_ch3.adb (Constrain_Corresponding_Record): For the case
4743 of the subtype created for a record component, do not mark
4744 the subtype as frozen. For one thing, this is anomalous (in
4745 particular, the base type might not itself be frozen yet);
4746 furthermore, proper freezing of the subtype must happen in any
4747 case. So, we just mark the subtype as requiring delayed freezing
4748 (and we'll actually freeze it when generating the init_proc of
4749 the enclosing record).
4750 Also change the name of the constrained record subtype (append a
4751 'C' so that it is clearly different from the unconstrained record
4752 type, "related_idV") to make debugging easier.
4753 (Process_Full_View): When creating a full subtype for a pending

4776 parameter of a null-excluding access type, there is access check
4777 on entry, so set Suppress_Assignment_Checks on generated statement
4778 that assigns actual to parameter block.
4779 * sinfo.ads: Document additional use of Suppress_Assignment_Checks.

4874 and the completion will appear in the same declarative part,
4875 create elaboration flag.
4876 * exp_util.adb (Set_Elaboration_Flag): If the subprogram body
4877 is a completion of a declaration in the same declarative part,
4878 and the subprogram has had its address taken, add elaboration
4879 check inside the subprogram body, to detect elaboration errors
4880 that may occur through indirect calls.

5026 to DF_Id. Add new local variable DF_Call. Do not perform any
5027 elaboration-related checks on the call to the partial finalization

5029 warnings on expansion-related code.
5030 * sem_elab.adb (Check_A_Call): Move constant Access_Case to

10820 * exp_util.adb (Build_Allocate_Deallocate_Proc): Rewrite
10821 the logic that generates a runtime check to determine the

10824 even if they appear as generic actuals.
10825 (Find_Object): Detect
10826 a special case that involves interface class-wide types because
10827 the object appears as a complex expression.

10910 * s-taskin.ads: Minor comment fix.
10911 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
10912 just direct dependents. If this is actually an abort, each task
10913 will take care of aborting its dependents, so all dependents will
10914 get aborted, as before. However, when this is called the second
10915 time from Vulnerable_Complete_Master "for convenience" (i.e. to
10916 kill off tasks waiting at terminate alternatives), aborting
10917 indirect dependents is wrong, because it causes some unrelated
10918 tasks to get aborted.

11419 * a-suenst.adb: strings.utf_encoding.strings (Decode): Check
11420 explicitly whether value is in range of Character, because the
11421 library is typically compiled with range checks disabled, and
11422 we cannot rely on the implicit check on the argument of 'Val.

12664 the original one. the modification of the name must preserve
12665 the source location of the original, to prevent spurious errors
12666 when compiling with style checks if the declaration involves
12667 more than one entity.
