 412
 413 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 414

 420         * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
 421         Ada_2020, along the same lines as the other Ada version pragmas.
 422

 429         * sem_aggr.adb (Resolve_Record_Aggregate):
 430         Rewrite bounds of aggregate subexpressions which may depend on
 431         discriminants of the enclosing aggregate.
 432
 433 2017-09-08  Yannick Moy  <moy@adacore.com>
 434

 438
 439         * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
 440         calling Renamed_Entity on an entity which cannot be a renaming.
 441
 442 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 443
 444         * exp_aggr.adb: Add with & use clause for Urealp.
 445         (Aggr_Assignment_OK_For_Backend): Accept (almost all)
 446         elementary types instead of just discrete types.
 447         * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
 448         * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
 449         Be prepared for the FP zero value in the memset case.  Add small
 450         guard.
 451
 452 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 453
 454         * s-htable.adb (Static_HTable.Reset): Use aggregate instead
 455         of loop.
 456
 457 2017-09-08  Hristian Kirtchev  <kirtchev@adacore.com>
 458
 459         * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
 460         of New_Copy because the latter leaves the syntactic structure of
 461         the tree inconsistent (a child is accessible through two parents)
 462         and prevents proper replication of itypes by subsequent calls
 463         to New_Copy_Tree.
 464         * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
 465         New_Copy because the latter leaves the syntactic structure of the
 466         tree inconsistent (a child is accessible through two parents)
 467         and prevents proper replication of itypes by subsequent calls
 468         to New_Copy_Tree.
 469         * sem_util.adb (In_Subtree): New routine.
 470         (New_Copy_Tree): Reimplemented.
 471         * sem_util.ads (In_Subtree): New routine.
 472         (New_Copy_Tree): Reimplemented.
 473
 474 2017-09-08  Ed Schonberg  <schonberg@adacore.com>
 475
 476         * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
 477         for aspect Default_Value is a static scalar value, but it does
 478         not freeze the type. Yhis allows for subsequent representation
 479         clauses for the type.
 480
 481 2017-09-08  Javier Miranda  <miranda@adacore.com>
 482
 483         * sem_ch8.adb (Find_Direct_Name.Undefined): Do
 484         not add entries into the undefined reference table when we are
 485         compiling with errors ignored.
 486
 487 2017-09-08  Ed Schonberg  <schonberg@adacore.com>
 488
 489         * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
 490         check if the instance is within an enclosing instance body. The
 491         formal package was legal in the enclosing generic, and is
 492         legal in the enclosing instantiation.  This optimisation may be
 493         applicable elsewhere, and it also removes spurious errors that
 494         may arise with on-the-fly processing  of instantiations that
 495         contain Inline_Always subprograms.
 496
 497 2017-09-08  Vincent Celier  <celier@adacore.com>

 506 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 507
 508         * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
 509
 510 2017-09-08  Justin Squirek  <squirek@adacore.com>
 511
 512         * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
 513         case to handle underscore flags.
 514         * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
 515         new procedure to handle underscores.

 517 2017-09-08  Javier Miranda  <miranda@adacore.com>
 518
 519         * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
 520         divisions with fixed point results to avoid generating twice
 521         the runtime check on divide by zero.
 522         * checks.adb (Apply_Divide_Checks): Ensure that operands are
 523         not evaluated twice (once for their runtime checks and once for
 524         their regular computation).
 525
 526 2017-09-08  Yannick Moy  <moy@adacore.com>
 527
 528         * sem_prag.adb (Analyze_Part_Of): Add missing
 529         return statements after issuing errors.  Add detection of
 530         out-of-order item and single concurrent type.

 659         * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks

 661         expression that includes a formal of the enclosing subprogram,
 662         In such cases, the accessibility level of the actual is that of

 675         and empty strings. Empty strings cause trouble because they can
 676         have super-null ranges (e.g. 100..10), which causes Ext_Copy to
 677         be empty, which causes an array index out of bounds.

1069         which was not there (that's the primary semantic change of this
1070         commit); also, when comparing a single concurrent object with
1071         its corresponding concurrent type rely on equality of types,
1072         not of objects (because that's simpler to code).

1076         of task types and single tasks objects; similar for references
1077         in the protected operations and entries of protected types and
1078         single protected objects (in all these cases the current instance
1079         behaves as an implicit parameter and must not be mentioned in

1454         * exp_ch3.ads (Init_Secondary_Tags): Adding new formal

1457         the elaboration of dispatch tables.

1460         the initialization of the object components from the
1461         initialization of its dispatch tables.  (Init_Secondary_Tags):
1462         Adding new formal (Init_Tags_List) and adjusting calls to
1463         Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;

1466         * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile

1507         generic parameters, because unlike ordinary formal parameters,
1508         generic formals only act as input/ outputs if they are explicitly
1509         mentioned in a Global contract.

1576         types -- just do it for dispatching calls.  Misc cleanup.
1577         * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
1578         remove qualifications and type conversions. Fix various bugs
1579         where only a single level of qualification or conversion was
1580         removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
1581         instead of "X".

1639         * binde.adb (Find_Elab_Order): Do not run Elab_Old unless

1641         Elab_Old and use the order chosen by Elab_Old, possibly with
1642         debugging printouts comparing the two orders."  Now it means
1643         "do not run Elab_New." This is of use if there are bugs that

1692         expression, resolve the alternatives of the conditional using
1693         the base type of the target entity, because the alternatives
1694         may have distinct subtypes. This is particularly relevant if

1701         the LHS after the assignment, rather than to the aggregate. This
1702         is more efficient than creating a temporary for the aggregate,
1703         and prevents back-end crashes when the aggregate includes a

1758         that is a proper body corresponding to a stub, we defer the
1759         adjustment of the sloc until after the correct adjustment has
1760         been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1761         the adjustment, because it will be outside the range in (the old,
1762         incorrect) S_Adjustment.
1763         * inline.adb: Use named notation for readability and uniformity.
1764         * sinput-l.adb: Minor improvements to debugging output printed

1775         * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
1776         case when Op is of kind N_Qualified_Expression. In this case,
1777         the function is called recursively on the subexpression like in
1778         other cases.
1779         * make.adb: Minor reformatting
1780

1851         of a subprogram.
1852         * freeze.adb (Freeze_Entity): Use Get_Classwide_Pragma when
1853         freezing a subprogram, to complete the generation of the

1866
1867         * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1868         we include the proper header. Otherwise, we just declare the necessary
1869         things from the capabilities library. This is so we can build on
1870         machines without that library, while still enabling that library.
1871         At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1872         simply return 0 if the library is not present, or not included
1873         in the link.
1874

1896         * pprint.ads (Expression_Image) Add new generic formal flag
1897         Hide_Temp_Derefs.  The flag defaults to False; CodePeer will

1899         * pprint.adb (Expression_Image) If the new flag is set, then
1900         suppress the ".all" suffix when displaying a dereference whose
1901         prefix is a use of a value-capturing compiler temp of the sort

2103         Move Ada.Command_Line.Response_File to System.Response_File,
2104         and make Ada.Command_Line.Response_File into a rename of
2105         System.Response_File. This is to avoid having gnatbind depend
2106         Ada.Command_Line, which would damage the bootstrap process now

2108         * gnatbind.adb: Avoid dependence on
2109         Ada.Command_Line. Depend on System.Response_File instead
2110         of Ada.Command_Line.Response_File. Change one call to
2111         Ada.Command_Line.Command_Name to use Fill_Arg.  Change one call
2112         to Ada.Command_Line.Argument_Count to use Arg_Count.
2113         * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
2114
2115 2017-09-06  Bob Duff  <duff@adacore.com>
2116
2117         * frontend.adb (Frontend): Skip -gnatec=gnat.adc
2118         switch, because we've already read gnat.adc by default.

2121
2122         * exp_ch5.adb (Get_Default_Iterator): Replace
2123         "Assert(False)" with "return Iter", because if an iterable
2124         type is derived from a noniterable one, then we won't find an
2125         overriding or inherited default iterator.

2181         rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram

2202
2203         * freeze.adb (Freeze_Entity): Do not generate a freeze
2204         node for a generic unit, even if it includes delayed aspect
2205         specifications. Freeze nodes for generic entities must never
2206         appear in the tree that reaches the back-end of the compiler.
2207

2220         explicit delayed aspects but may inherit delayed aspects from its
2221         parent type, analyze aspect at freeze point for proper capture
2222         of an inherited aspect.

2248         of the right-hand side has stored constraint, use its values
2249         (except for those that are renamings of parent discriminants)
2250         to produce additional assignments for the discriminants of the
2251         left-hand side, which are invisible in the righ-hand side and
2252         not retrievable as selected components.

2255
2256         * sem_util.adb (Needs_One_Formal): The first formal of such a

2276         * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
2277         No_Return flag to instance if pragma applies to generic unit. This
2278         must be done explicitly because the pragma does not appear
2279         directly in the generic declaration (unlike the corresponding
2280         aspect specification).
2281
2282 2017-09-06  Eric Botcazou  <ebotcazou@adacore.com>

2292         derived type with a mixture of renamed and constrained parent
2293         discriminants, the constraint for the target must obtain the
2294         discriminant values from both the operand and from the stored
2295         constraint for it, given that the constrained discriminants are
2296         not visible in the object.
2297         * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2298         side may be derived from that of the left-hand side (as in the
2299         case of an assignment with a change of representation) so the
2300         discriminant to be used in the retrieval of the value of the
2301         component must be the entity in the type of the right-hand side.

2319         properly an attribute reference 'Loop_Entry that appears in the

2332         replace the entity of the alternative as well as the type,
2333         to prevent inconsistencies between the entity and the type.

2441
2442         * sem_util.adb (Is_Object_Reference): A function call is an

2971         equality. A call to it is transformed into a call to its alias,
2972         which is the predefined equality. A dispatching call thus uses

3180         for restricted targets.

3187
3188         * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3189         to find primitive ops, instead of using an Identifier that will
3190         later be looked up. This is necessary because these ops are not
3191         necessarily visible at all places where we need to call them.

3197         references are fully conformant if they are both expansions
3198         of the discriminant of a protected type, within one of the
3199         protected operations. One occurrence may be expanded into a
3200         constant declaration while the other is an input parameter to
3201         the corresponding generated subprogram.

3207         types and verifying them.
3208         (Analyze_Object_Declaration): Add a
3209         call to Check_Null_Excluding_Components for static verification
3210         of non-initialized objects.
3211         * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added

3234
3235         * sem_ch8.adb (Premature_Usage): If the premature usage of
3236         an entity is as the expression in its own object decaration,
3237         rewrite the reference as Any_Id to prevent cascaded errors or
3238         compiler loops when such an entity is used in an address clause.

3251
3252         * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3253         controlling actual in a prefixed call, preserve the original node
3254         information if the prefix itself has been rewritten, for ASIS use.
3255

3257
3258         * exp_ch6.adb (Insert_Post_Call_Actions):
3259         Code clean up. Insert the post-call actions after an enclosing
3260         procedure call when N denotes a function call and appears as an
3261         actual parameter in the procedure call.

3266         for the component, also reject the attribute if the component
3267         doesn't end on a byte boundary and its scalar storage order is
3268         different from that of the enclosing record type.

3303
3304         * sem_util.ads, sem_util.adb (Might_Raise): New function
3305         that replaces Is_Exception_Safe, but has the opposite
3306         sense. Is_Exception_Safe was missing various cases -- calls inside
3307         a pragma Debug, calls inside an 'if' or assignment statement,
3308         etc. Might_Raise now walks the entire subtree looking for things
3309         that can raise.
3310         * exp_ch9.adb (Is_Exception_Safe): Remove.
3311         (Build_Protected_Subprogram_Body): Replace call to
3312         Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3313         constants where possible).
3314         * exp_ch7.adb: Rename Is_Protected_Body -->
3315         Is_Protected_Subp_Body. A protected_body is something different
3316         in the grammar.

3342 2017-04-28  Ed Schonberg  <schonberg@adacore.com>
3343

3345         Interrupt_Handler and Attach_Handler): Generate reference
3346         to protected operation to prevent spurious warnings about
3347         unreferenced entities. Previous scheme failed with style checks
3348         enabled.

3351
3352         * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3353         that follows an expression function must not be relocated to
3354         the generated body, because it applies to the code that follows.
3355

3357
3358         * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3359         Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3360         code that might violate the more stringent checking for 'Access
3361         introduced in Ada 2005.

3384
3385         * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3386         node between access types, freeze the designated type as well,
3387         so that dispatch table pointers are created in the proper scope,
3388         and not in the constructed body of the expression function.
3389
3390 2017-04-28  Bob Duff  <duff@adacore.com>
3391
3392         * alloc.ads (Nodes_Initial): Go back to previous value. The large

3416
3417         * sem_res.adb (In_Instance_Code): New predicate in
3418         Valid_Conversion, to determine whether a type conversion appears
3419         as (or within) an actual for a formal object.  Type conversions
3420         in instances are not rechecked in Valid_Conversion because
3421         visibility changes between generic location andi instance may
3422         lead to spurious errors, but conversions within an actual must be
3423         fully checked, and they are not fully resolved when pre-analyzing
3424         the actuals.

3427
3428         * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3429         New_Copy_Tree instead of Relocate_Node as any subsequent copies
3430         of the relocated node will have mangled Parent pointers.
3431         * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3432         tables used in conjunction with entity and itype replication.
3433         (Visit_Entity): Rewrite the restriction on which entities
3434         require duplication.  The restriction now includes all types.

3475         (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3476         parameters.  Rename local variables and adjust recursive call.
3477         Rework final scan of the field list and implement warnings on the

3488         For efficiency, cache results of Is_Internal_File_Name and
3489         Is_Predefined_File_Name in the Units table. This avoids a lot
3490         of repeated text processing.

3492 2017-04-27  Emmanuel Briot  <briot@adacore.com>
3493

3497
3498         * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3499         allow the use of regular equality over elements in contracts.
3500         (Formal_Model): Ghost package containing model functions that are
3501         used in subprogram contracts.

3505         (No_Overlap): Removed, model functions should be used instead.
3506         (Equivalent_Keys): Functions over cursors are removed. They were
3507         awkward with explicit container parameters.
3508         * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3509         allow the use of regular equality over elements in contracts.

3521 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
3522
3523         * exp_util.adb (Replace_Entity): The prefix of a 'Result
3524         attribute reference in a post- condition is the subprogram to
3525         which the condition applies. If the condition is inherited
3526         by a type extension, the prefix becomes a reference to the
3527         inherited operation, but there is no need to create a wrapper
3528         for this operation, because 'Result is expanded independently
3529         when elaborating the postconditions.
3530
3531 2017-04-27  Bob Duff  <duff@adacore.com>
3532
3533         * sinput.adb: Minor code cleanup.
3534         * namet.adb (Append): Create faster versions of
3535         Append(String) and Append(Name_Id) by using slice assignment
3536         instead of loops.
3537         * sem_util.adb (In_Instance): Speed this up by removing
3538         unnecessary tests; Is_Generic_Instance is defined for all
3539         entities.
3540         * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3541         Remove unused function.
3542         * alloc.ads (Nodes_Initial): Use a much larger value, because
3543         the compiler was spending a lot of time copying the nodes table
3544         when it grows. This number was chosen in 1996, so is rather out
3545         of date with current memory sizes. Anyway, it's virtual memory.
3546         Get rid of Orig_Nodes_...; use Node_... instead.
3547         * atree.adb (Lock): Do not release the Nodes tables; it's a
3548         waste of time.
3549         Orig_Nodes_ ==> Nodes_
3550         * nlists.adb: Orig_Nodes_ ==> Nodes_
3551         * g-table.adb: Remove unused "with" clause.
3552         * g-table.ads, table.ads: Remove Big_Table_Type, which should
3553         not be used by clients.
3554         * g-dyntab.adb (Last_Allocated): New function
3555         to encapsulate T.P.Last_Allocated, which I'm thinking of changing.

3580         * sem_util.adb (Compile_Time_Constraint_Error): Merge the
3581         processing for Ada 83 and instances.
3582         (Object_Access_Level): Merge the processing for indexed components

3593
3594         * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
3595         of Expand_Dispatching_Call. If the denoted subprogram has a
3596         class-wide precondition, this is the only precondition that
3597         applies to the call, rather that the class-wide preconditions
3598         that may apply to the body that is executed. (This is specified
3599         in AI12-0195).

3608
3609         * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
3610         is itself inherited it does not carry any contract information,
3611         so examine its parent operation which is its Alias.
3612
3613 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
3614
3615         * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3616         prefix can be an object reference in which case Obj'Image (X)
3617         can only be interpreted as an indexing of the parameterless
3618         version of the attribute.
3619         * par-ch4.adb (P_Name): An attribute reference can be the prefix of
3620         an indexing or a slice operation if the attribute does not require
3621         parameters. In Ada2012 'Image also belongs in this category,
3622         and A'Image (lo .. hi) is legal and must be parsed as a slice.

3626         * exp_ch4.adb: Minor reformatting.
3627         * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
3628         disable the CodePeer and C generation modes. Similar to the
3629         opposite actions done in CodePeer mode.

3654         If the table grows and then shrinks back to empty, we won't necessarily
3655         point back to the empty array. Code cleanups.

3816         and in SPARK, and to determine whether a wrapper is needed for
3817         an inherited operation.

3969         class-wide clone of a subprogram with classwide conditions. The

3971         clone. The inherited operation becomes a similar wrapper to which
3972         modified conditions apply, and the call to the clone includes
3973         the proper conversion in a call the parent operation.

3986         and rewrite original body as a wrapper as a wrapper for a call to

3989         * freeze.adb (Check_Inherited_Conditions): For an inherited
3990         subprogram that inherits a classwide condition, build spec and
3991         body of corresponding wrapper so that call to inherited operation
3992         gets the modified conditions.
3993         * contracts.adb (Analyze_Contracts): If analysis of classwide
3994         condition has created a clone for a primitive operation, analyze

4150         (__gnat_bracktrace):
4151         Add a dummy definition for the compiler (__gnat_eh_personality,
4152         __gnat_rcheck_04, __gnat_rcheck_10) (__gnat_rcheck_19,
4153         __gnat_rcheck_20, __gnat_rcheck_21) (__gnat_rcheck_30,

4159         file.
4160         (__gnat_Unwind_ForcedUnwind): Adjust prototype.
4161         (db): Constify msg_format.
4162         (get_call_site_action_for): Don't use void arithmetic.

4177
4178         * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
4179         modifications in functional containers.
4180         * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4181         to improve readablity. Subprograms are separated between basic
4182         operations, constructors and properties. Universally quantified
4183         formulas in contracts are factorized in independant functions
4184         with a name and a comment.  Names of parameters are improved.

4189
4190 2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>
4191
4192         * sem_res.adb (Resolve_Type_Conversion): Do not
4193         install a predicate check here since this is already done during
4194         the expansion phase. Verify whether the operand satisfies the
4195         static predicate (if any) of the target type.
4196         * sem_ch3.adb (Analyze_Object_Declaration): Do
4197         not install a predicate check if the object is initialized by
4198         means of a type conversion because the conversion is subjected
4199         to the same check.
4200
4201 2017-04-27  Tristan Gingold  <gingold@adacore.com>
4202
4203         * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be
4204         replaced by their variants).
4205
4206 2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>

4216         Ada95.
4217
4218 2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>
4219
4220         * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4221         the loop which detects potential enclosing transient scopes. The
4222         loop now terminates much earlier as transient scopes are bounded
4223         by packages and subprograms.
4224
4225 2017-04-27  Claire Dross  <dross@adacore.com>
4226
4227         * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4228         allow the use of regular equality over elements in contracts.
4229         (Cursor): Type is now public so that it can be used in
4230         model functions.
4231         (Formal_Model): Ghost package containing
4232         model functions that are used in subprogram contracts.
4233         (Current_To_Last): Removed, model functions should be used
4234         instead.
4235         (First_To_Previous): Removed, model functions should
4236         be used instead.
4237         (Strict_Equal): Removed, model functions
4238         should be used instead.
4239         (Append): Default parameter value
4240         replaced by new wrapper to allow more precise contracts.
4241         (Insert): Default parameter value replaced by new wrapper to
4242         allow more precise contracts.
4243         (Delete): Default parameter
4244         value replaced by new wrapper to allow more precise contracts.
4245         (Prepend): Default parameter value replaced by new wrapper to
4246         allow more precise contracts.

4248         value replaced by new wrapper to allow more precise contracts.
4249         (Delete_Last): Default parameter value replaced by new wrapper
4250         to allow more precise contracts.

4255         for object declarations.
4256         (Expand_SPARK_N_Object_Declaration): New routine.
4257         * sem_elab.adb (Check_A_Call): Include calls to the
4258         Default_Initial_Condition procedure of a type under the SPARK
4259         elaboration checks umbrella.
4260
4261 2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>

4263         * sem.adb (Analyze): Diagnose an illegal iterated component
4264         association.
4265         * sem_util.ads, sem_util.adb
4266         (Diagnose_Iterated_Component_Association): New routine.
4267
4268 2017-04-27  Bob Duff  <duff@adacore.com>
4269
4270         * adaint.c (__gnat_get_current_dir): Return 0 in length if
4271         getcwd fails.
4272         * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
4273         exception if getcwd failed.
4274
4275 2017-04-27  Yannick Moy  <moy@adacore.com>
4276
4277         * exp_dbug.adb, exp_dbug.ads (Get_External_Name): Prefix ghost
4278         entities with special prefix.
4279
4280 2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>
4281
4282         * debug.adb Change the documentation of switch -gnatd.s.
4283         * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4284         to manage the secondary stack when an enclosing scope already
4285         performs this functionality (aka relaxed management). Switch
4286         -gnatd.s may be used to force strict management in which case
4287         the block will manage the secondary stack unconditionally. Add
4288         a guard to stop the traversal when encountering a package or a
4289         subprogram scope.
4290
4291 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
4292
4293         * sem_res.adb (Resolve_Call): Refine further the handling of
4294         limited views of return types in function calls. If the function
4295         that returns a limited view appears in the current unit,
4296         we do not replace its type by the non-limited view because
4297         this transformation is performed int the back-end. However,
4298         the type of the call itself must be the non-limited view, to
4299         prevent spurious resolution errors.
4300
4301 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
4302
4303         * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4304         Removed, proposed implementation using generics for class-wide
4305         preconditions proved impractical.
4306         (Class_Wide_Clone): New attribute of subprogram. Designates
4307         subprogram created for primitive operations with class-wide
4308         pre/postconditions that contain calls to other primitives. The
4309         clone holds the body of the original primitive, but the
4310         pre/postonditions do not apply to it. The original body is
4311         rewritten as a wrapper for a call to the clone.
4312         (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4313         the flag is set, no code for the corresponding pre/postconditions
4314         is inserted into its body.
4315

4367         of data structures.
4368         * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4369         child of Ada.Containers. It provides functional indefinite unbounded

4406         dimensions of operands if node has been analyzed already, because
4407         previous analysis and dimension checking will have removed the
4408         dimension information from the operands.

4496         * sinput-p.adb: Use regular fat pointers, with bounds checking,
4497         for source buffers.  Fix misc obscure bugs.
4498         * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4499         checking, for source buffers.  Modify representation clause for
4500         Source_File_Record as appropriate.  Move Source_File_Index_Table
4501         from spec to body, because it is not used outside the body.
4502         Move Set_Source_File_Index_Table into the private part, because
4503         it is used only in the body and in children.  Use trickery to
4504         modify the dope in the generic instantiation case.  It's ugly,
4505         but not as ugly as the previous method.  Fix documentation.
4506         Remove obsolete code.
4507         * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
4508         indexing in source buffers.

4525         Remove variants that include a Supress parameter. These routines
4526         are never used, and were introduced before the current scope-based
4527         check suppression method.

4578         scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
4579         the Internal_Source buffer. This removes the incorrect call to "="
4580         the customer noticed.
4581         Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4582         eventually need to eliminate them altogether. Or else get rid
4583         of zero-origin addressing.

5269         the spec when it needs to ignore all SPARK_Mode pragmas found

5378         (Expand_Actuals): Generate proper copy-back for a validation
5379         variable when it acts as the argument of a type conversion.
5380         * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5381         predicate to operate on type qualifications.
5382
5383 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
5384
5385         * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5386         Minor reformatting.
5387
5388 2017-04-25  Bob Duff  <duff@adacore.com>
5389
5390         * sem_prag.adb (No_Return): Give an error if the pragma applies
5391         to a body. Specialize the error for the specless body case,
5392         as is done for (e.g.) pragma Convention.
5393         * debug.adb: Add switch -gnatd.J to disable the above legality
5394         checks. This is mainly for use in our test suite, to avoid
5395         rewriting a lot of illegal (but working) code.  It might also
5396         be useful to customers. Under this switch, if a pragma No_Return
5397         applies to a body, and the procedure raises an exception (as it
5398         should), the pragma has no effect. If the procedure does return,
5399         execution is erroneous.
5400
5401 2017-04-25  Bob Duff  <duff@adacore.com>
5402
5403         * exp_ch6.adb (Expand_Actuals): This is the
5404         root of the problem. It took N as an 'in out' parameter, and in
5405         some cases, rewrote N, but then set N to Original_Node(N). So
5406         the node returned in N had no Parent. The caller continued
5407         processing of this orphaned node. In some cases that caused a
5408         crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5409         and trips over the Empty Parent). The solution is to make N an
5410         'in' parameter.  Instead of rewriting it, return the list of
5411         post-call actions, so the caller can do the rewriting later,
5412         after N has been fully processed.
5413         (Expand_Call_Helper): Move most of Expand_Call here. It has
5414         too many premature 'return' statements, and we want to do the
5415         rewriting on return.
5416         (Insert_Post_Call_Actions): New procedure to insert the post-call
5417         actions in the appropriate place. In the problematic case,
5418         that involves rewriting N as an Expression_With_Actions.
5419         (Expand_Call): Call the new procedures Expand_Call_Helper and
5420         Insert_Post_Call_Actions.
5421

5428 2017-04-25  Javier Miranda  <miranda@adacore.com>
5429
5430         * exp_unst.adb (Subp_Index): Adding missing
5431         support for renamings and functions that return a constrained
5432         array type (i.e. functions for which the frontend built a
5433         procedure with an extra out parameter).

5453         * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5454         convention Stdcall, which has a number of exceptions. Convention
5455         is legal on a component declaration whose type is an anonymous
5456         access to subprogram.

5458 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

5472         to enable/disable this warning.
5473         (WA_Warnings): Set warning on late dispatching primitives.
5474         * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember

5476         * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5477         New subprogram.

5490 2017-04-25  Bob Duff  <duff@adacore.com>
5491
5492         * s-fileio.adb (Close): When a temp file is
5493         closed, delete it and clean up its Temp_File_Record immediately,
5494         rather than waiting until later.
5495         (Temp_File_Record): Add File
5496         component, so Close can know which Temp_File_Record corresponds
5497         to the file being closed.
5498         (Delete): Don't delete temp files,
5499         because they are deleted by Close.
5500         (Open): Set the File component
5501         of Temp_File_Record. This requires moving the creation of the
5502         Temp_File_Record to the end, after the AFCB has been created.

5516         potentially blocking subprograms.
5517

5519
5520         * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
5521         concerning inheritance of class-wide preconditions do not apply
5522         to postconditions.

5529
5530         * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5531         conversions from float to integer in GNATprove mode.
5532         (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5533         to call Apply_Type_Conversion_Checks, so that range checks
5534         are properly positioned when needed on conversions, including
5535         when converting from float to integer.  (Determine_Range): In
5536         GNATprove mode, take into account the possibility of conversion
5537         from float to integer.
5538         * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5539         check on conversions from fixed-point to integer, not anymore
5540         on conversions from floating-point to integer, when in GNATprove
5541         mode.

5553         checks.
5554         * einfo.adb Node36 is now used as Validated_Object.
5555         (Validated_Object): New routine.

5563         variables to avoid extra reads and copies of the prefix.
5564         * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5565         variables in order to reflect any changes done in the variable
5566         back into the original object.

5577
5578         * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5579         Analyze_Pre_Post_Condition, to implement the legality checks
5580         mandated by AI12-0131: Pre'Class shall not be specified for an
5581         overriding primitive subprogram of a tagged type T unless the
5582         Pre'Class aspect is specified for the corresponding primitive
5583         subprogram of some ancestor of T.

5585 2017-04-25  Bob Duff  <duff@adacore.com>
5586
5587         * sem_ch8.adb (Use_One_Type): If a use_type_clause
5588         is redundant, set its Used_Operations to empty. This is only
5589         necessary for use clauses that appear in the parent of a generic
5590         child unit, because those use clauses get reanalyzed when we
5591         instantiate the generic, and we don't want the Used_Operations
5592         carried over from the original context (where it was probably
5593         not redundant).

5603         * exp_prag.adb (Expand_Pragma_Check): Use Source_Index
5604         (Current_Sem_Unit) to find the correct casing.
5605         * par.adb (Par): Null out Current_Source_File, to ensure that
5606         the above bugs won't rear their ugly heads again.

5620         tag of a tagged result.
5621         * exp_intr.adb (Expand_Dispatching_Constructor_Call):
5622         if CodePeer_Mode is True, then don't generate the
5623         tag checks for the result of call to an instance of
5624         Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a

5636         (Expand_Concatenate): When optimization is enabled, also expand
5637         the operation out-of-line if the concatenation is present within
5638         the expression of the declaration of a library-level object and
5639         not only if it is the expression of the declaration.

5641 2017-04-25  Bob Duff  <duff@adacore.com>
5642
5643         * freeze.adb (Freeze_Object_Declaration): Do
5644         not Remove_Side_Effects if there is a pragma Linker_Section,
5645         because in that case we want static initialization in the
5646         appropriate section.

5653
5654         * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5655         handle the proposed changes to rules concerning potentially
5656         unevaluated expressions, to include selected components that
5657         do not depend on discriminants, and indexed components with
5658         static indices.
5659         * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5660         predicate in quantified expression, and fix bugs in the handling

5680         info if it comes from sources.
5681
5682 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

5686         of a controlled type.

5702         Preanalyze_Spec_Expression so that resolution takes place as well.
5703         * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5704         internal calls that appear in preconditions of protected
5705         operations, in default values for same, and in contract guards
5706         for contract cases in SPARK.

5715         (Double): Likewise.

5717         * a-numaux-x86.ads: Fix package description.
5718         * a-numaux-x86.adb (Is_Nan): Minor tweak.
5719         (Reduce): Adjust and complete description. Call Is_Nan instead of
5720         testing manually. Use an integer temporary to hold rounded value.
5721         * a-numaux-darwin.adb (Reduce): Likewise.
5722         (Is_Nan): New function.

5725
5726         * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5727         on analysis of prefix whose type is a current instance of a
5728         synchronized type, but where the prefix itself is an entity that
5729         is an object.

5731 2017-04-25  Ed Schonberg  <schonberg@adacore.com>
5732
5733         * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5734         the identity of callable entities therein, because they have been
5735         properly resolved, and prefixed calls may have been rewritten
5736         as normal calls.

5741         the expression of the pragma/aspect Secondary_Stack_Size to
5742         internal type System.Parameters.Size_Type before assigning
5743         it to the Secondary_Stack_Size component of the task type's

5759         adding documentation on why we generate multiplications instead
5760         of divisions (needed to avoid expressions whose computation with
5761         large numbers may cause division by 0).

5764
5765         * erroutc.adb (Set_Specific_Warning_Off,
5766         Set_Warnings_Mode_Off): Use the correct source file for
5767         Stop. Was using Current_Source_File, which is only valid during
5768         parsing. Current_Source_File will have a leftover value from
5769         whatever file happened to be parsed last, because of a with_clause
5770         or something.
5771
5772 2017-04-25  Bob Duff  <duff@adacore.com>
5773

5775         to In_Predefined_Unit, but including GNAT units.
5776         * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5777         with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5778         because Should_Ignore_Pragma was not working reliably outside
5779         the parser, because Current_Source_File is not valid.
5780         * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5781         * par-prag.adb: Call Should_Ignore_Pragma_Par.

5849
5850         * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5851         of prefix whose type is a current instance of a synchronized
5852         type. If the prefix is an object this is an external call (or
5853         requeue) that can only access public operations of the object. The
5854         previous predicate was too restrictive, and did not allow public
5855         protected operations, only task entries.

5863         * einfo.adb (Is_Anonymous_Access_Type): New routine.
5864         * einfo.ads Update the placement of
5865         E_Anonymous_Access_Subprogram_Type along with all subtypes that
5866         mention the ekind.
5867         (Is_Anonymous_Access_Type): New routine.
5868         * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5869         master for an access type subject to pragma No_Heap_Finalization.
5870         * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5871         allocated or deallocated does not finalization actions if the
5872         associated access type is subject to pragma No_Heap_Finalization.
5873         * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5874         * par-prag.adb Pragma No_Heap_Finalization does not need special
5875         processing from the parser.
5876         * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5877         ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5878         * sem_prag.adb Add an entry in table Sig_Flags for pragma
5879         No_Heap_Finalization.
5880         (Analyze_Pragma): Add processing for
5881         pragma No_Heap_Finalization. Update various error messages to
5882         use Duplication_Error.
5883         * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5884         * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5885         and corresponding pragma id.
5886
5887 2017-04-25  Bob Duff  <duff@adacore.com>
5888
5889         * freeze.adb (Freeze_Record_Type): Use the
5890         underlying type of the component type to determine whether it's
5891         elementary. For representation clause purposes, a private type
5892         should behave the same as its full type.
5893         * fname.ads, fname.adb (Is_Predefined_File_Name):
5894         Make sure things like "system.ali" are recognized as predefined.
5895
5896 2017-04-25  Javier Miranda  <miranda@adacore.com>
5897
5898         * debug.adb: Update documentation of -gnatd.6.
5899
5900 2017-04-25  Ed Schonberg  <schonberg@adacore.com>
5901
5902         * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5903         element iterator when the name is an overloaded function call,
5904         one of whose interpretations yields an array.
5905
5906 2017-04-25  Bob Duff  <duff@adacore.com>
5907
5908         * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5909         Is_Internal_Unit_Name): New functions for operating on unit
5910         names, as opposed to file names. There's some duplicated code
5911         with fname.adb, which is unfortunate, but it seems like we don't
5912         want to add dependencies here.
5913         * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5914         to Is_Predefined_Unit_Name; the former was wrong, because Uname
5915         is not a file name at all.
5916         * fname.ads, fname.adb: Document the fact that
5917         Is_Predefined_File_Name and Is_Internal_File_Name can be called
5918         for ALI files, and fix the code so it works properly for ALI
5919         files. E.g. these should return True for "system.ali".
5920
5921 2017-04-25  Justin Squirek  <squirek@adacore.com>
5922
5923         * exp_util.adb (Add_Invariant): Removed,
5924         code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5925         and Add_Own_Invariant.  (Add_Invariant_Check): Used
5926         for adding runtime checks from any kind of invariant.
5927         (Add_Inherited_Invariant): Generates invariant checks for
5928         class-wide invariants (Add_Interface_Invariants): Removed, code
5929         moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5930         Create a types own invariant procedure (Add_Parent_Invariants):
5931         Removed, code moved to Build_Invariant_Procedure_Body
5932         (Build_Invariant_Procedure_Body): Add refactored calls
5933         and integrated code from Add_Parent_Invariants and
5934         Add_Interface_Invariants.
5935         (Process_Type): Removed, the
5936         relavant code was inlined into both Add_Own_Invariant and
5937         Add_Inherited_Invariant.
5938
5939 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

5943
5944 2017-04-25  Pascal Obry  <obry@adacore.com>
5945
5946         * s-taprop-mingw.adb: Do not check for CloseHandle in
5947         Finalize_TCB.
5948
5949 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
5950
5951         * sem_util.adb (Check_Part_Of_Reference):
5952         Continue to examine the context if the reference appears within
5953         an expression function.
5954
5955 2017-04-25  Justin Squirek  <squirek@adacore.com>
5956
5957         * exp_ch7.adb, exp_ch7.ads Remove Build_Invariant_Procedure_Body
5958         and Build_Invariant_Procedure_Declaration.
5959         * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5960         and Build_Invariant_Procedure_Declaration from exp_ch7
5961         and break-out Is_Untagged_Private_Derivation from
5962         Build_Invariant_Procedure_Body.
5963         (Replace_Type_References):
5964         Append an extra parameter to allow for dispatching replacements
5965         and add the corrasponding logic.
5966         (Type_Invariant): Remove
5967         Replace_Typ_Refs and replace its references with calls to
5968         Replace_Type_References.
5969         * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5970
5971 2017-04-25  Bob Duff  <duff@adacore.com>
5972
5973         * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5974         that returns True when appropriate.
5975         * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5976         when compiling predefined files.
5977         * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5978         "gnat.adc" should not be considered a predefined file name.
5979         That required (or at least encouraged) a lot of cleanup of global
5980         variable usage. We shouldn't be communicating information via
5981         the global name buffer.
5982         * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5983         * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5989         configuration file whose name is a directory.
5990
5991 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
5992
5993         * sem_attr.adb, sem_ch5.adb: Minor reformatting.
5994

6003         * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
6004         Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
6005         Add String_To_Name with no side effects.

6013
6014         * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
6015         reserved words inside pragmas. This is necessary to allow the
6016         pragma name Interface to be used in pragma Ignore_Pragma.
6017         * par.adb: Minor comment fix.
6018
6019 2017-04-25  Javier Miranda  <miranda@adacore.com>
6020
6021         * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.
6022         * rtsfind.ads (RE_Type_Is_Abstract): Renamed as Is_Abstract.
6023         * exp_disp.adb (Make_DT): Update occurrences of RE_Type_Is_Abstract.
6024         * exp_intr.adb (Expand_Dispatching_Constructor_Call): Update
6025         occurrences of RE_Type_Is_Abstract
6026
6027 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
6028
6029         * exp_util.adb (Build_Chain): Account for ancestor
6030         subtypes while traversing the derivation chain.
6031

6043         the first pass over an assignment statement with target names,
6044         to prevent the generation of subtypes (such as discriminated
6045         record components)that may carry the target name outside of the
6046         tree for the assignment. The subtypes will be generated when
6047         the assignment is reanalyzed in full.
6048         (Analyze_Target_Name): Handle properly class-wide types.
6049
6050 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

6057         (Add_Inherited_Tagged_DIC): There is really no need to preanalyze
6058         and resolve the triaged expression because all substitutions
6059         refer to the proper entities.  Update the replacement of
6060         references.
6061         (Build_DIC_Procedure_Body): Add formal parameter
6062         For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6063         are now only processed when freezing occurs.  Build a body only
6064         when one is needed.
6065         (Entity_Hash): Removed.
6066         (Map_Types): New routine.
6067         (Replace_Object_And_Primitive_References): Removed.

6079         * sem_ch7.adb (Preserve_Full_Attributes): Propagate the DIC
6080         properties of the private type to the full view in case the full
6081         view derives from a parent type and inherits a DIC pragma.
6082         * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6083         DIC pragma is placed at the top of a declarative region.
6084
6085 2017-04-25  Arnaud Charlet  <charlet@adacore.com trojanek>
6086
6087         * a-tasatt.adb: Complete previous change and use an unsigned
6088         int to avoid overflow checks.
6089
6090 2017-04-25  Ed Schonberg  <schonberg@adacore.com>
6091
6092         * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize
6093         the error message when the attribute reference is an actual in
6094         a call to a subprogram inherited from a generic formal type with
6095         unknown discriminants, which makes the subprogram and its formal
6096         parameters intrinsic (see RM 6.3.1 (8) and (13)).
6097
6098 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
6099
6100         * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,
6101         sem_prag.adb: Minor reformatting.
6102
6103 2017-04-25  Bob Duff  <duff@adacore.com>
6104
6105         * sem_attr.adb (Type_Key): Add code in the
6106         recursive Compute_Type_Key to protect against fetching the source
6107         code for Standard, in case a component of the type is declared
6108         in Standard. There was already code to do this for the original
6109         type, but not for its components.
6110

6118
6119         * sem_res.adb (Set_Mixed_Mode_Operand): A universal
6120         real conditional expression can appear in a fixed-type context
6121         and must be resolved with that context to facilitate the code
6122         generation to the backend.
6123
6124 2017-04-25  Ed Schonberg  <schonberg@adacore.com>
6125
6126         * einfo.adb, einfo.ads (Body_Needed_For_Inlining): New flag,
6127         to indicate whether during inline processing, when some unit U1
6128         appears in the context of a unit U2 compiled for instantiation
6129         or inlining purposes, the body of U1 needs to be compiled as well.
6130         * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
6131         context is a package declaration.
6132         * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,

6140         the presence of a target_name in the right hand side of the
6141         assignment being parsed.
6142         * par-ch4.adb (P_Name): If the name is a target_name, mark the
6143         enclosing assignment node accordingly.
6144         * par-ch5.adb (P_Assignment_Statement): Set Current_Assign_Node
6145         appropriately.
6146         * sem_ch5.adb (Analyze_Assignment): Disable expansion before
6147         analyzing RHS if the statement has target_names.
6148         * sem_aggr.adb (Resolve_Iterated_Component_Association): Handle
6149         properly choices that are subtype marks.
6150         * exp_ch5.adb: Code cleanup.

6157         * sem_ch3.adb, sem_ch13.adb: Address ??? comments.
6158
6159 2017-04-25  Arnaud Charlet  <charlet@adacore.com trojanek>
6160

6162         conversion.
6163
6164 2017-04-25  Doug Rupp  <rupp@adacore.com>
6165
6166         * init.c (__gnat_error_handler) [vxworks]: Turn on sigtramp
6167         handling for ppc64-vx7.

6180         improvements. This just isn't important after all these years.

6998         called function is in the extended main unit then no action is
6999         needed since the back-end handles this case.

7577         can coexist.
7578         * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7579         parameter of type array. This avoids the global variable, and
7580         allows bounds checking (which is normally defeated by the tables
7581         packages). It also ensures that the Elab_Order is read-only
7582         to Bindgen.
7583         * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7584         subprograms that need it, as above.
7585         * debug.adb: Document new -dp switch. Modify doc of old -do
7586         switch.
7587         * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7588         and Bindgen.  Move writing of closure (-R and -Ra switches)
7589         to Binde; that's more convenient.

7592
7593         * sem_ch6.adb (Analyze_Expression_Function): If the expression
7594         function is a completion, all entities referenced in the
7595         expression are frozen. As a consequence, a reference to an
7596         uncompleted private type from an enclosing scope is illegal.

7599
7600         * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7601         (Analyze_Subprogram_Body_Helper): At the occurrence of an
7602         expression function declaration that is a completion, its
7603         expression causes freezing (AI12-0103).
7604

7615
7616         * exp_ch3.adb (Default_Initialize_Object): Do not default
7617         initialize an object when it is of a task type and restriction
7618         No_Tasking is in effect because the initialization is obsolete.
7619         * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
7620         restriction No_Tasking is in effect.
7621         (Build_Master_Renaming): Do not rename a master when restriction
7622         No_Tasking is in effect.

7625
7626         * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
7627         the legality of An others clause applies as well to a choice in
7628         an Iterated_component_ association.
7629         (Resolve_Iterated_Component_Association): An others choice
7630         is legal.
7631         * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
7632         Iterated_Component_Association is not static.

7654
7655         * sem_util.ads, sem_util.adb (Choice_List): Move function here
7656         from sem_aggr.adb, for use elsewhere.
7657         * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.

7659         Iterated_Component_Present.
7660         * exp_aggr.adb: Use Choice_List throughout, to handle

7662         (Gen_Loop): Generate proper loop for an
7663         Iterated_Component_Association: loop variable has the identifier
7664         of the original association. Generate a loop even for a single
7665         component choice, in order to make loop parameter visible in
7666         expression.
7667         (Flatten): An Iterated_Component_Association is not static.
7668
7669 2017-01-13  Yannick Moy  <moy@adacore.com>
7670
7671         * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7672         float exponentiation for statically known small negative values
7673         is the reciprocal of the exponentiation for the opposite value
7674         of the exponent.
7675         * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
7676         Ensure that the value of float exponentiation for negative values
7677         is the reciprocal of the exponentiation for the opposite value
7678         of the exponent.
7679         * inline.adb (Expand_Inlined_Call): Fix the count
7680         for the number of generated gotos.
7681
7682 2017-01-13  Yannick Moy  <moy@adacore.com>
7683
7684         * inline.adb: Code cleanup.
7685         * sem_util.adb (Is_OK_Volatile_Context): Add
7686         expression in delay statement as OK for volatile context.
7687
7688 2017-01-13  Ed Schonberg  <schonberg@adacore.com>
7689
7690         * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7691         mode a choice that is a subtype with a static predicate is
7692         replaced by the values it covers. This transformation must not
7693         be performed in ASIS mode, to preserve the source for analysis.
7694
7695 2017-01-13  Justin Squirek  <squirek@adacore.com>
7696
7697         * nlists.ads: Correct minor typo.

7700
7701         * sem_ch13.adb: Minor reformatting and typo fix.
7702
7703 2017-01-13  Ed Schonberg  <schonberg@adacore.com>
7704
7705         * par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
7706         Iterated_Component_Association is a named association in an
7707         array aggregate.
7708         * sem_aggr.adb (Resolve_Iterated_Component_Association): New
7709         procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7710         and resolve the discrete choices and the expression of the
7711         new construct.
7712         * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7713         Loop_Actions and Box_Present are attributes of
7714         N_Iterated_Component_Association nodes. Box_Present is always
7715         False in this case.
7716         * sprint.adb (Sprint_Node): An Iterated_Component_Association
7717         has a Discrete_Choices list, as specified in the RM. A
7718         Component_Association for aggregate uses instead a Choices list.
7719         We have to live with this small inconsistency because the new
7720         construct also has a defining identifier, and there is no way
7721         to merge the two node structures.
7722
7723 2017-01-13  Yannick Moy  <moy@adacore.com>
7724
7725         * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

7730 2017-01-13  Ed Schonberg  <schonberg@adacore.com>
7731
7732         * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
7733         Analyze_Declarations, to analyze and resolve the expressions of
7734         aspect specifications in the current declarative list, so that
7735         the expressions have proper entity and type info.  This is needed
7736         for ASIS when there is no subsequent expansion to generate this
7737         semantic information.
7738         * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7739         original expression, to suppress cascaded errors when expression
7740         has been constant-folded.
7741         (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7742         ASIS mode, because there is no subsequent expansion to decorate
7743         the tree.
7744
7745 2017-01-13  Yannick Moy  <moy@adacore.com>
7746
7747         * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
7748         New function to detect when a call may be inlined or not in
7749         GNATprove mode.
7750         (Expand_Inlined_Call): Ensure that a temporary
7751         is always created in the cases where a type conversion may be
7752         needed on an input parameter in GNATprove mode, so that GNATprove
7753         sees the check to perform.
7754         * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7755         when not applicable due to actual requiring type conversion
7756         with possible check but no temporary value can be copied for
7757         GNATprove to see the check.

8892         the expression is the result of constant-folding a type conversion
8893         whose expression is a variable with a known static value.
