36 * freeze.adb (Late_Freeze_Subprogram): Following AI05-151,
37 a function can return a limited view of a type declared
38 elsewhere. In that case the function cannot be frozen at the end
39 of its enclosing package. If its first use is in a different unit,
40 it cannot be frozen there, but if the call is legal the full view
41 of the return type is available and the subprogram can now be
42 frozen. However the freeze node cannot be inserted at the point
43 of call, but rather must go in the package holding the function,
44 so that the backend can process it in the proper context.

2804 Exception_Information is used to produce useful debugging
2805 information for the programmer. However, it was also used to
2806 implement the stream attributes for type Exception_Occurrence. The
2807 latter requires a stable and portable interface, which meant
2808 that we couldn't include a symbolic traceback. A separate set of
2809 routines was used to provide symbolic tracebacks under program
2810 control (i.e. not automatically). The goal of this ticket is
2811 to provide such automatic tracebacks, so the change here is to
2812 split the two functionalities: Exception_Information gives the
2813 maximally useful information for debugging (i.e. it now includes
2814 a symbolic traceback when a decorator is set, and it can be
2815 improved freely in the future without disturbing streaming).
2816 Untailored_Exception_Information always uses hexadecimal addresses

2989 2014-07-30 Javier Miranda <miranda@adacore.com>
2991 * Makefile.rtl, gnat_rm.texi, i-cpp.adb, i-cpp.ads, impunit.adb,
2992 rtsfind.ads: Remove references to package Interfaces.CPP since this
2993 package is no longer needed.
2995 2014-07-30 Bob Duff <duff@adacore.com>
2997 * s-taasde.adb (Timer_Queue): Don't use a
2998 build-in-place function call to initialize the Timer_Queue.
2999 * s-traent.adb, s-traent.ads, s-traent-vms.adb, s-traent-vms.ads:
3000 Turn off polling in these units, because otherwise we get
3001 elaboration circularities with Ada.Exceptions when the -gnatP
3003 * s-tassta.adb (Create_Task): Make sure independent tasks
3004 are created with Parent = Environment_Task. This was not true,
3005 for example, in s-interr.adb, when Interrupt_Manager does "new
3006 Server_Task"; the Server_Task had Parent = Interrupt_Manager,
3007 which is wrong because the master is determined by the access
3008 type, which is at library level.
3009 * s-tasuti.adb (Make_Independent): Avoid setting Parent; it is
3010 now set correctly by Create_Task.
3011 (Make_Passive): Remove the workaround for the race condition in
3013 * frontend.adb (Frontend): Revert to previous method of detecting
3014 temporary configuration pragma files, recognizing such files by
3015 ".tmp" in the name. This is more general than detecting pragmas
3016 Source_File_Name_Project, because it allows any tool to use
3017 this naming convention, no matter the content of the file.
3018 * gnat_ugn.texi: Document this naming convention.
3020 2014-07-30 Robert Dewar <dewar@adacore.com>

3029 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3031 * sem_ch5.adb: Improve error recovery.
3032 * inline.adb (Build_Body_To_Inline): Set Full_Analysis to false
3033 before analyzing the body, so that in GNATprove mode there is
3034 no light expansion. Whatever expansion is required by SPARK will
3035 be performed when analysing the inlined code.
3037 2014-07-30 Bob Duff <duff@adacore.com>
3039 * s-tataat.adb, s-tataat.ads, a-tasatt.adb: Minor comment fixes.

3048 * sem.ads (Scope_Table_Entry): New component Locked_Shared_Objects.
3049 * sem_ch8.adb (Push_Scope): Initialize Locked_Shared_Objects.
3050 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Handle the case where
3051 the call returns an unconstrained type: in this case there is
3052 already a transient scope, and we should not establish a new one.
3053 * exp_ch7.adb (Insert_Actions_In_Scope_Around): New formal Clean. If
3054 True, also insert cleanup actions in the tree.
3055 (Wrap_Transient_Declaration): Call Insert_Actions_In_Scope_Around
3056 with Clean set True.
3058 2014-07-30 Arnaud Charlet <charlet@adacore.com>
3060 * s-taskin.ads (Direct_Index, Direct_Index_Range,
3061 Direct_Attribute_Element, Direct_Attribute_Array,
3062 Direct_Index_Vector, Direct_Attributes, Is_Defined,
3063 Indirect_Attributes): Removed. (Atomic_Address,
3064 Attribute_Array, Attributes): New.
3065 * s-tasini.ads, s-tasini.adb (Proc_T, Initialize_Attributes,
3066 Finalize_Attributes_Link, Initialize_Attributes_Link): Removed.
3067 (Finalize_Attributes): Reimplement.
3068 * s-tassta.adb (Create_Task): Remove call to
3069 Initialize_Attributes_Link (Free_Task, Vulnerable_Free_Task):
3070 Replace Finalize_Attributes_Link by Finalize_Attributes.
3071 * a-tasatt.ads, a-tasatt.adb, s-tataat.ads, s-tataat.adb:
3072 Reimplement from scratch, using a simpler and more efficient
3074 * s-tporft.adb (Register_Foreign_Thread): Remove now obsolete comment.
3075 * s-parame.ads, s-parame-hpux.ads,
3076 * s-parame-vms-alpha.ads, s-parame-vms-ia64.ads,

3078 Default_Attribute_Count.
3080 2014-07-30 Olivier Hainque <hainque@adacore.com>
3082 * vxworks-ppc-link.spec: New file. Extra link
3083 instructions for ppc-vxworks.
3084 * vxworks-crtbe-link.spec: Likewise, for ZCX related support.
3085 * system-vxworks-ppc.ads: Adjust linker options to use spec files.
3086 * system-vxworks-arm.ads: Likewise.
3087 * gcc-interface/Makefile.in: Enable .spec files.
3089 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3091 * sem_aggr.adb: Minor comment reformatting.
3093 2014-07-30 Robert Dewar <dewar@adacore.com>
3095 * sem_util.ads, sem_util.adb (Is_Junk_Name): Removed.
3096 * sem_warn.adb (Has_Junk_Name): New function
3097 (Check_References): Use Has_Junk_Name to delete junk warnings

3099 (Warn_On_Unreferenced_Entity): ditto.
3100 (Warn_On_Useless_Assignment): ditto.
3102 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3104 * checks.adb (Insert_Valid_Check): Do not check for the packed
3105 array type of a prefix that is an access type.
3107 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3109 * sem_attr.adb (Eval_Attribute): Evaluate the GNAT attribute
3110 Unconstrained_Array even if prefix is not frozen yet, as can
3111 occur with a private subtype used as a generic actual.
3113 2014-07-30 Gary Dismukes <dismukes@adacore.com>
3115 * sem_attr.adb: Minor reformatting.
3117 2014-07-30 Pat Rogers <rogers@adacore.com>
3119 * gnat_rm.texi: Corrected minor wording error in description
3120 of No_Exception_Registration.
3122 2014-07-30 Yannick Moy <moy@adacore.com>
3124 * einfo.ads, einfo.adb: New flag Is_Inlined_Always for use in GNATprove
3125 mode. Realphabetize two subprograms.
3126 * inline.adb (Cannot_Inline): Use Is_Inlined_Always in GNATprove mode.
3127 (Can_Be_Inlined_In_GNATprove_Mode): Adapt to possible Empty Body_Id.
3128 (Check_And_Build_Body_To_Inline): Use Is_Inlined_Always in GNATprove
3130 (Expand_Inline_Call): Use Is_Inlined_Always in GNATprove mode.
3131 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not use
3132 Is_Inline in GNATprove mode.
3133 (Analyze_Subprogram_Specification):
3134 Set Is_Inlined_Always at subprogram entity creation.
3135 * sem_res.adb (Resolve_Call): Do not deal with inlining during
3136 pre-analysis. Issue warning on call to possibly inlined
3137 subprogram when body not seen.
3139 2014-07-30 Yannick Moy <moy@adacore.com>
3141 * lib-xref.adb (Generate_Reference): Add special
3142 case for compiler-generated formals in GNATprove mode.
3144 2014-07-30 Yannick Moy <moy@adacore.com>
3146 * sem_ch6.adb: Add comments.
3148 2014-07-30 Thomas Quinot <quinot@adacore.com>

3152 2014-07-30 Robert Dewar <dewar@adacore.com>
3154 * sem_aggr.adb, sem_res.adb: Minor reformatting.
3156 2014-07-30 Thomas Quinot <quinot@adacore.com>
3158 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
3159 Bit_Order): Set Reverse_Bit_Order on the base type of the
3160 specified first subtype.
3162 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3164 * inline.adb (Expand_Inlined_Call): Use a renaming declaration
3165 to capture the value of actuals of a limited type rather than
3166 an object declaration, to prevent spurious errors when analyzing
3169 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3171 * sem_ch4.adb (Analyze_Type_Conversion): Treat an inlined body
3172 as an instance, and inhibit semantic checks on already analyzed
3173 code to prevent spurious errors.
3175 2014-07-30 Arnaud Charlet <charlet@adacore.com>
3177 * a-exctra.ads ("="): New function, to restore compatibility.
3179 2014-07-30 Pascal Obry <obry@adacore.com>

3182 routine to use the OS dst setting.
3184 2014-07-30 Pat Rogers <rogers@adacore.com>
3186 * gnat_ugn.texi: Minor correction to description of -gnatw.K.
3188 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3190 * sem_util.adb (Wrong_Type): Disable some checks equally within
3191 instances and within inlined bodies, to suppress spurious type
3192 errors on already analyzed code.
3193 * sem_aggr.adb (Check_Expr_OK_In_Limited_Aggregate): Expression
3194 is legal in an inlined body, juts as it is in an instance body.
3196 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3198 * sem_res.adb (Resolve_Unchecked_Conversion): Within an inlined
3199 body the operand of an unchecked conversion may be a literal, in
3200 which case its type is the target type of the conversion. This
3201 is in contrast to conversions in other contexts, where the
3202 operand cannot be a literal and must be resolvable independent
3205 2014-07-30 Pierre-Marie Derodat <derodat@adacore.com>
3207 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Create a
3208 mere scalar constant instead of a reference for a renaming of

3213 2014-07-30 Robert Dewar <dewar@adacore.com>
3215 * s-tasuti.adb, s-tasuti.ads, einfo.ads, sem_prag.adb, s-taasde.adb,

3220 s-interr-sigaction.adb, s-os_lib.adb, s-fileio.adb: Minor reformatting
3221 & code reorganization.
3223 2014-07-30 Bob Duff <duff@adacore.com>
3225 * s-tassta.adb, sem_util.ads: Minor reformatting.
3227 2014-07-30 Yannick Moy <moy@adacore.com>
3229 * inline.adb (Build_Body_To_Inline): Detect when
3230 subprogram has multiple returns, or not a single last return
3231 statement, in GNATprove mode.
3232 (Cannot_Inline): Simplify logic to handle case of GNATprove
3235 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3237 * sem_ch6.adb: Stubs are not subject to inlining.
3239 2014-07-30 Bob Duff <duff@adacore.com>
3241 * s-tasuti.ads, s-tasuti.adb (Make_Independent): Change this
3242 from a procedure to a function, so that it can more easily be
3243 called before the "begin" of a task.
3244 * s-taasde.ads (Delay_Block): Make this type immutably limited,
3245 so we can use a build-in-place function call to initialize
3246 Timer_Queue in the body.
3247 * a-rttiev.adb, s-asthan-vms-alpha.adb, s-asthan-vms-ia64.adb,
3248 * s-interr.adb, s-interr-hwint.adb, s-interr-sigaction.adb,
3249 * s-interr-vms.adb, s-taasde.adb: Each independent task now calls
3250 Make_Independent before reaching its "begin", to avoid race
3251 conditions. This causes the activating task to wait until after
3252 Make_Independent is complete before proceeding. In addition,
3253 we initialize data structures used by independent tasks before
3254 activating those tasks, to avoid possible use of uninitialized data.
3255 * s-interr.ads, s-intman.ads, s-taspri-posix.ads, s-tasdeb.ads:
3256 Minor comment fixes.
3258 2014-07-30 Bob Duff <duff@adacore.com>
3260 * a-exctra.ads, s-traent-vms.ads, s-traent.ads (Tracebacks_Array): Move
3261 the declaration of Tracebacks_Array from Ada.Exceptions.Traceback to
3262 System.Traceback_Entries (s-traent.ads and s-traent-vms.ads). Add
3263 subtypes renaming Tracebacks_Array in Ada.Exceptions.Traceback.
3264 * g-debpoo.adb: Refer to Tracebacks_Array in its new home.
3266 2014-07-30 Arnaud Charlet <charlet@adacore.com>
3268 * a-tasatt.adb: Remove old comments.
3270 2014-07-30 Yannick Moy <moy@adacore.com>
3272 * einfo.ads (Is_Inlined): Document new use in GNATprove mode.
3273 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Add comments
3274 to explain rationale for inlining or not in GNATprove mode.
3275 (Expand_Inlined_Call): In GNATprove mode, set Is_Inlined flag
3276 to False when inlining is not possible.
3277 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Set Is_Inlined
3278 flag to indicate that subprogram is fully inlined. To be reversed
3279 if inlining problem is found.
3280 * sem_res.adb (Resolve_Call): Set Is_Inlined flag to False when
3281 call in potentially unevaluated context.
3283 2014-07-30 Jose Ruiz <ruiz@adacore.com>
3285 * s-tarest.adb, s-tarest.ads: Fix comments.
3287 2014-07-30 Robert Dewar <dewar@adacore.com>
3289 * exp_attr.adb, checks.adb, sem_util.adb, sem_util.ads, sem_attr.adb:
3290 Change No_Scalar_Parts predicate to Scalar_Part_Present and
3291 invert sense of test. This avoids the "not No_xxx" situation
3292 which is always ugly.
3294 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3296 * inline.adb (Expand_Inlined_Call): When generating code for
3297 an internal subprogram the expansion uses the location of the
3298 call, so that gdb can skip over it. In GNATprove mode we want to
3299 preserve slocs of original subprogram when expanding an inlined
3300 call, to obtain better warnings, even though subprogram appears
3301 not to come from source if it is the inlining of a subprogram
3302 body without a previous spec.
3304 2014-07-30 Eric Botcazou <ebotcazou@adacore.com>
3306 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Reject array
3307 types with atomic components.
3309 2014-07-30 Thomas Quinot <quinot@adacore.com>
3311 * Make-generated.in: Remove now unnecessary targets after s-oscons
3314 2014-07-30 Yannick Moy <moy@adacore.com>
3316 * sem_res.adb (Resolve_Call): Use ultimate alias
3317 of callee when available.
3319 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3321 * sem_ch6.adb (Analyze_Expression_Function): To check whether
3322 an expression function is a completion, use the specification of
3323 the previous declaration, not its entity, which may be internally
3324 generated in an inlined context.
3326 2014-07-30 Doug Rupp <rupp@adacore.com>
3328 * adaint.c (__gnat_tmp_name) [__ANDROID__]: Default to putting
3329 temp files in /cache directory unless overridden by TMPDIR.
3331 2014-07-30 Jose Ruiz <ruiz@adacore.com>
3333 * s-tassta.adb, s-tarest.adb (Initialize, Create_Task,
3334 Create_Restricted_Task): Remove redundant check. Number_Of_CPUs returns
3335 type CPU, so it can never be greater than CPU_Range'Last.
3337 2014-07-30 Bob Duff <duff@adacore.com>
3339 * s-taskin.ads: Minor comment fix.
3341 2014-07-30 Thomas Quinot <quinot@adacore.com>

3355 * Make-generated.in: Remove generation of s-oscons.ads, only
3356 generate the xoscons utility, in runtime-agnostic rules.
3357 * gcc-interface/Makefile.in: Clean up rules. Remove VMS parts,
3358 no longer supported.
3360 2014-07-30 Bob Duff <duff@adacore.com>
3362 * exp_ch6.adb (Add_Task_Actuals_To_Build_In_Place_Call): New
3363 parameter Chain to be used in the allocator case.
3364 (Make_Build_In_Place_Call_In_Allocator): If the allocated object
3365 has tasks, wrap the code in a block that will activate them,
3366 including the usual finalization code to kill them off in case
3367 of exception or abort.
3369 2014-07-30 Robert Dewar <dewar@adacore.com>
3371 * treepr.adb, treepr.ads; Reorganize documentation for new pp routines
3372 Remove renamings (don't work for gdb).
3373 (par): New synonym for p (avoid gdb ambiguities).
3374 * inline.adb, sem_ch6.adb, sem_ch13.adb: Minor reformatting.
3376 2014-07-30 Bob Duff <duff@adacore.com>
3378 * exp_ch9.ads, sem_prag.adb, exp_ch4.adb, sem_ch13.adb: Minor comment
3380 * treepr.ads, treepr.adb (ppp): Make this debugging routine
3381 accept any type covered by Union_Id.

3393 of predicate aspect on entity other than a type.
3395 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3397 * sem_ch6.adb (Body_Has_Contract): New predicate to determine
3398 when a subprogram body without a previous spec cannot be inlined
3399 in GNATprove mode, because it includes aspects or pragmas that
3400 generate a SPARK contract clause.
3401 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): A subprogram
3402 instance cannot be inlined.
3404 2014-07-30 Robert Dewar <dewar@adacore.com>

3428 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3430 * par-ch4.adb (Is_Parameterless_Attribute): 'Result is a
3431 parameterless attribute, and a postondition can mention an
3432 indexed component or a slice whose prefix is an attribute
3435 2014-07-30 Robert Dewar <dewar@adacore.com>
3437 * sprint.adb (Sprint_Node_Actual, case Object_Declaration):
3438 Avoid bomb when printing package Standard.
3440 2014-07-30 Ed Schonberg <schonberg@adacore.com>
3442 * sem_elab.adb (Check_Internal_Call_Continue): If an elaboration
3443 entity is created at this point, ensure that the name of the
3444 flag is unique, because the subprogram may be overloaded and
3445 other homonyms may also have elaboration flags created on the fly.
3447 2014-07-30 Hristian Kirtchev <kirtchev@adacore.com>
3449 * sem_attr.adb (Analyze_Array_Component_Update): New routine.
3450 (Analyze_Attribute): Major cleanup of attribute

3455 (Check_Component_Reference): Removed.
3456 (Resolve_Attribute): Remove the return statement and ??? comment
3457 following the processing for attribute 'Update. As a result,
3458 the attribute now freezes its prefix.

3462 * exp_ch4.adb (Apply_Accessibility_Check): Do
3463 not call Base_Address() in VM targets.

3826 * sem_ch3.adb (Constrain_Corresponding_Record): For the case
3827 of the subtype created for a record component, do not mark
3828 the subtype as frozen. For one thing, this is anomalous (in
3829 particular, the base type might not itself be frozen yet);
3830 furthermore, proper freezing of the subtype must happen in any
3831 case. So, we just mark the subtype as requiring delayed freezing
3832 (and we'll actually freeze it when generating the init_proc of
3833 the enclosing record).
3834 Also change the name of the constrained record subtype (append a
3835 'C' so that it is clearly different from the unconstrained record
3836 type, "related_idV") to make debugging easier.
3837 (Process_Full_View): When creating a full subtype for a pending

3961 is a completion of a declaration in the same declarative part,
3962 and the subprogram has had its address taken, add elaboration

9995 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
9996 just direct dependents. If this is actually an abort, each task

9999 time from Vulnerable_Complete_Master "for convenience" (i.e. to
10000 kill off tasks waiting at terminate alternatives), aborting
10001 indirect dependents is wrong, because it causes some unrelated

11750 when compiling with style checks if the declaration involves
11751 more than one entity.
