 400         * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
 401         Ada_2020, along the same lines as the other Ada version pragmas.
 402
 403 2017-09-08  Gary Dismukes  <dismukes@adacore.com>
 404
 405         * sem_ch12.adb: Minor typo fixes and reformatting.
 406
 407 2017-09-08  Yannick Moy  <moy@adacore.com>
 408
 409         * sem_aggr.adb (Resolve_Record_Aggregate):
 410         Rewrite bounds of aggregate subexpressions which may depend on
 411         discriminants of the enclosing aggregate.
 412
 413 2017-09-08  Yannick Moy  <moy@adacore.com>
 414
 415         * sem_ch5.adb: Prevent assertion failure on illegal code.
 416
 417 2017-09-08  Yannick Moy  <moy@adacore.com>
 418
 419         * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
 420         calling Renamed_Entity on an entity which cannot be a renaming.
 421
 422 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 423
 424         * exp_aggr.adb: Add with & use clause for Urealp.
 425         (Aggr_Assignment_OK_For_Backend): Accept (almost all)
 426         elementary types instead of just discrete types.
 427         * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
 428         * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
 429         Be prepared for the FP zero value in the memset case.  Add small
 430         guard.
 431
 432 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 433
 434         * s-htable.adb (Static_HTable.Reset): Use aggregate instead
 435         of loop.
 436
 437 2017-09-08  Hristian Kirtchev  <kirtchev@adacore.com>
 438
 439         * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
 440         of New_Copy because the latter leaves the syntactic structure of
 441         the tree inconsistent (a child is accessible through two parents)
 442         and prevents proper replication of itypes by subsequent calls
 443         to New_Copy_Tree.
 444         * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
 445         New_Copy because the latter leaves the syntactic structure of the
 446         tree inconsistent (a child is accessible through two parents)
 447         and prevents proper replication of itypes by subsequent calls
 448         to New_Copy_Tree.
 449         * sem_util.adb (In_Subtree): New routine.
 450         (New_Copy_Tree): Reimplemented.
 451         * sem_util.ads (In_Subtree): New routine.
 452         (New_Copy_Tree): Reimplemented.
 453
 454 2017-09-08  Ed Schonberg  <schonberg@adacore.com>
 455
 456         * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
 457         for aspect Default_Value is a static scalar value, but it does
 458         not freeze the type. Yhis allows for subsequent representation
 459         clauses for the type.
 460
 461 2017-09-08  Javier Miranda  <miranda@adacore.com>
 462
 463         * sem_ch8.adb (Find_Direct_Name.Undefined): Do
 464         not add entries into the undefined reference table when we are
 465         compiling with errors ignored.
 466
 467 2017-09-08  Ed Schonberg  <schonberg@adacore.com>
 468
 469         * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
 470         check if the instance is within an enclosing instance body. The
 471         formal package was legal in the enclosing generic, and is
 472         legal in the enclosing instantiation.  This optimisation may be
 473         applicable elsewhere, and it also removes spurious errors that
 474         may arise with on-the-fly processing  of instantiations that
 475         contain Inline_Always subprograms.
 476
 477 2017-09-08  Vincent Celier  <celier@adacore.com>
 478
 479         * gnatcmd.adb: Disregard empty argument of GNAT driver.

 482
 483         * checks.adb (Insert_Valid_Check): Manually decorate
 484         the generated temporary for range valdity checks.
 485
 486 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 487
 488         * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
 489
 490 2017-09-08  Justin Squirek  <squirek@adacore.com>
 491
 492         * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
 493         case to handle underscore flags.
 494         * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
 495         new procedure to handle underscores.
 496
 497 2017-09-08  Javier Miranda  <miranda@adacore.com>
 498
 499         * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
 500         divisions with fixed point results to avoid generating twice
 501         the runtime check on divide by zero.
 502         * checks.adb (Apply_Divide_Checks): Ensure that operands are
 503         not evaluated twice (once for their runtime checks and once for
 504         their regular computation).
 505
 506 2017-09-08  Yannick Moy  <moy@adacore.com>
 507
 508         * sem_prag.adb (Analyze_Part_Of): Add missing
 509         return statements after issuing errors.  Add detection of
 510         out-of-order item and single concurrent type.

 639         * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
 640         when the actual is a construct that involves a dereference of an
 641         expression that includes a formal of the enclosing subprogram,
 642         In such cases, the accessibility level of the actual is that of

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

1210         scope, and IAP has a body, IAP must be frozen before SI. If

1431
1432         * einfo.ads, einfo.adb (Access_Disp_Table_Elab_Flag): New
1433         attribute. Defined for record types and subtypes.
1434         * exp_ch3.ads (Init_Secondary_Tags): Adding new formal
1435         (Init_Tags_List) to facilitate generating separate code in the
1436         IP routine to initialize the object components and for completing
1437         the elaboration of dispatch tables.
1438         * exp_ch3.adb (Build_Init_Procedure): Improve the code
1439         generated in the IP routines by means of keeping separate
1440         the initialization of the object components from the
1441         initialization of its dispatch tables.  (Init_Secondary_Tags):
1442         Adding new formal (Init_Tags_List) and adjusting calls to
1443         Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
1444         adjusting also calls to Ada.Tags.Register_Interface_Offset
1445         because the type of one of its formals has been changed.
1446         * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
1447         modified. Instead of receiving a pointer to an object this
1448         routine receives now a primary tag.
1449         (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
1450         additional formal: the tag of the primary dispatch table.
1451         * exp_disp.ads (Elab_Flag_Needed): New subprogram.
1452         * exp_disp.adb (Elab_Flag_Needed): New subprogram.

1484         is now consulted not only for abstract states and variables,
1485         but for all kinds of items.
1486         (Collect_Subprogram_Inputs_Outputs): Do not process formal
1487         generic parameters, because unlike ordinary formal parameters,
1488         generic formals only act as input/ outputs if they are explicitly
1489         mentioned in a Global contract.

1504         record declaration.
1505         * sem_dim.ads, sem_dim.adb (Copy_Dimensions_Of_Components): For a

1507         of the parent record to the corresponding component declarations
1508         of the derived record. These expressions are used among other
1509         things as default values in aggregates with box associations.

1527         first attempts to interpret as a malformed expression function.

1555         secondary stack for all functions that return limited tagged
1556         types -- just do it for dispatching calls.  Misc cleanup.
1557         * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
1558         remove qualifications and type conversions. Fix various bugs
1559         where only a single level of qualification or conversion was
1560         removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
1561         instead of "X".
1562         * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
1563         cleanup.

1569         functions.
1570         * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
1571         of body is a predicate function as well.
1572         (Resolve_Aspect_Expressions, Resolve_Name): For a component
1573         association, only the expression needs resolution, not the name.
1574         (Resolve_Aspect_Expressions, case Predicates): Construct and
1575         analyze the predicate function declaration in the scope of the
1576         type, before making the type and its discriminants visible.

1618
1619         * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1620         requested. Previously, the -do switch meant "run Elab_New and
1621         Elab_Old and use the order chosen by Elab_Old, possibly with
1622         debugging printouts comparing the two orders."  Now it means
1623         "do not run Elab_New." This is of use if there are bugs that
1624         cause Elab_New to crash.
1625         (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
1626         type conversions.

1642         <Sized_Component_Total_Round_RM_Size>: New local variable to
1643         accumulate the rounded RM_Size of components.  Update it for
1644         every component whose RM_Size is statically known.  Add missing
1645         guard to check that bit packing is really required before issuing
1646         the error about packing.  Swap condition for clarity's sake.

1671         entity of a mutable type and the right-hand side is a conditional
1672         expression, resolve the alternatives of the conditional using
1673         the base type of the target entity, because the alternatives
1674         may have distinct subtypes. This is particularly relevant if
1675         the alternatives are aggregates.

1677 2017-09-06  Ed Schonberg  <schonberg@adacore.com>

1680         aggregate that is the RHS of an assignment, apply the check to
1681         the LHS after the assignment, rather than to the aggregate. This
1682         is more efficient than creating a temporary for the aggregate,
1683         and prevents back-end crashes when the aggregate includes a
1684         dynamic "others' association.

1740         been computed. Otherwise, Adjust_Instantiation_Sloc will ignore

1755         * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
1756         case when Op is of kind N_Qualified_Expression. In this case,
1757         the function is called recursively on the subexpression like in
1758         other cases.
1759         * make.adb: Minor reformatting
1760
1761 2017-09-06  Justin Squirek  <squirek@adacore.com>
1762
1763         * einfo.adb (Set_Linker_Section_Pragma): Modify
1764         Set_Linker_Section_Pragma to be consistant with the "getter"

1846
1847         * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1848         we include the proper header. Otherwise, we just declare the necessary
1849         things from the capabilities library. This is so we can build on
1850         machines without that library, while still enabling that library.
1851         At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1852         simply return 0 if the library is not present, or not included
1853         in the link.
1854

1876         * pprint.ads (Expression_Image) Add new generic formal flag
1877         Hide_Temp_Derefs.  The flag defaults to False; CodePeer will

1879         * pprint.adb (Expression_Image) If the new flag is set, then
1880         suppress the ".all" suffix when displaying a dereference whose
1881         prefix is a use of a value-capturing compiler temp of the sort
1882         generated by Expr_Util.Remove_Side_Effects .

1911
1912         * sem_dim.adb (Analyze_Dimension): In an instance, a type

2082         * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
2083         Move Ada.Command_Line.Response_File to System.Response_File,
2084         and make Ada.Command_Line.Response_File into a rename of
2085         System.Response_File. This is to avoid having gnatbind depend
2086         Ada.Command_Line, which would damage the bootstrap process now

2088         * gnatbind.adb: Avoid dependence on
2089         Ada.Command_Line. Depend on System.Response_File instead

2101
2102         * exp_ch5.adb (Get_Default_Iterator): Replace

2229         (except for those that are renamings of parent discriminants)
2230         to produce additional assignments for the discriminants of the

2257         No_Return flag to instance if pragma applies to generic unit. This

2272         derived type with a mixture of renamed and constrained parent
2273         discriminants, the constraint for the target must obtain the
2274         discriminant values from both the operand and from the stored
2275         constraint for it, given that the constrained discriminants are
2276         not visible in the object.
2277         * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2278         side may be derived from that of the left-hand side (as in the

2280         discriminant to be used in the retrieval of the value of the
2281         component must be the entity in the type of the right-hand side.

2946         Refine predicate for the case where the primitive operation
2947         is a renaming of equality.  An overriding operation that is
2948         a user-defined renaming of predefined equality inherits its
2949         slot from the overridden operation. Otherwise it is treated
2950         as a predefined op and occupies the same predefined slot as
2951         equality. A call to it is transformed into a call to its alias,
2952         which is the predefined equality. A dispatching call thus uses
2953         the proper slot if operation is further inherited and called

3158         Simplify the expression for a fixed-fixed division to remove
3159         divisions by constants whenever possible, as an optimization
3160         for restricted targets.

3167
3168         * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3169         to find primitive ops, instead of using an Identifier that will
3170         later be looked up. This is necessary because these ops are not
3171         necessarily visible at all places where we need to call them.

3177         references are fully conformant if they are both expansions
3178         of the discriminant of a protected type, within one of the
3179         protected operations. One occurrence may be expanded into a
3180         constant declaration while the other is an input parameter to
3181         the corresponding generated subprogram.

3187         types and verifying them.
3188         (Analyze_Object_Declaration): Add a
3189         call to Check_Null_Excluding_Components for static verification
3190         of non-initialized objects.
3191         * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added

3214
3215         * sem_ch8.adb (Premature_Usage): If the premature usage of
3216         an entity is as the expression in its own object decaration,
3217         rewrite the reference as Any_Id to prevent cascaded errors or
3218         compiler loops when such an entity is used in an address clause.

3228         happens to cancel itself.
3229

3231
3232         * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3233         controlling actual in a prefixed call, preserve the original node
3234         information if the prefix itself has been rewritten, for ASIS use.

3246         for the component, also reject the attribute if the component
3247         doesn't end on a byte boundary and its scalar storage order is
3248         different from that of the enclosing record type.

3283
3284         * sem_util.ads, sem_util.adb (Might_Raise): New function
3285         that replaces Is_Exception_Safe, but has the opposite
3286         sense. Is_Exception_Safe was missing various cases -- calls inside
3287         a pragma Debug, calls inside an 'if' or assignment statement,
3288         etc. Might_Raise now walks the entire subtree looking for things
3289         that can raise.
3290         * exp_ch9.adb (Is_Exception_Safe): Remove.
3291         (Build_Protected_Subprogram_Body): Replace call to
3292         Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3293         constants where possible).
3294         * exp_ch7.adb: Rename Is_Protected_Body -->
3295         Is_Protected_Subp_Body. A protected_body is something different
3296         in the grammar.

3319         Do not generate an elaboration check if all checks have been
3320         suppressed.
3321
3322 2017-04-28  Ed Schonberg  <schonberg@adacore.com>
3323
3324         * sem_ch13.adb (Analyze_Aspect_Specifications, case
3325         Interrupt_Handler and Attach_Handler): Generate reference
3326         to protected operation to prevent spurious warnings about
3327         unreferenced entities. Previous scheme failed with style checks
3328         enabled.

3331
3332         * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3333         that follows an expression function must not be relocated to
3334         the generated body, because it applies to the code that follows.
3335

3337
3338         * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3339         Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3340         code that might violate the more stringent checking for 'Access
3341         introduced in Ada 2005.

3364
3365         * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3366         node between access types, freeze the designated type as well,
3367         so that dispatch table pointers are created in the proper scope,
3368         and not in the constructed body of the expression function.
3369
3370 2017-04-28  Bob Duff  <duff@adacore.com>
3371
3372         * alloc.ads (Nodes_Initial): Go back to previous value. The large
3373         value makes large compilations faster, but small compilations slower.
3374
3375 2017-04-28  Arnaud Charlet  <charlet@adacore.com>

3383         * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3384         internally-generated packages when outputting completion
3385         information.

3396
3397         * sem_res.adb (In_Instance_Code): New predicate in
3398         Valid_Conversion, to determine whether a type conversion appears
3399         as (or within) an actual for a formal object.  Type conversions
3400         in instances are not rechecked in Valid_Conversion because
3401         visibility changes between generic location andi instance may
3402         lead to spurious errors, but conversions within an actual must be
3403         fully checked, and they are not fully resolved when pre-analyzing
3404         the actuals.
3405

3407
3408         * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3409         New_Copy_Tree instead of Relocate_Node as any subsequent copies
3410         of the relocated node will have mangled Parent pointers.
3411         * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3412         tables used in conjunction with entity and itype replication.
3413         (Visit_Entity): Rewrite the restriction on which entities
3414         require duplication.  The restriction now includes all types.

3467         * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3468         For efficiency, cache results of Is_Internal_File_Name and
3469         Is_Predefined_File_Name in the Units table. This avoids a lot
3470         of repeated text processing.

3472 2017-04-27  Emmanuel Briot  <briot@adacore.com>
3473

3477
3478         * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3479         allow the use of regular equality over elements in contracts.
3480         (Formal_Model): Ghost package containing model functions that are
3481         used in subprogram contracts.
3482         (Current_To_Last): Removed, model functions should be used instead.
3483         (First_To_Previous): Removed, model functions should be used instead.

3485         (No_Overlap): Removed, model functions should be used instead.
3486         (Equivalent_Keys): Functions over cursors are removed. They were
3487         awkward with explicit container parameters.
3488         * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3489         allow the use of regular equality over elements in contracts.

3500
3501 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
3502
3503         * exp_util.adb (Replace_Entity): The prefix of a 'Result
3504         attribute reference in a post- condition is the subprogram to
3505         which the condition applies. If the condition is inherited
3506         by a type extension, the prefix becomes a reference to the
3507         inherited operation, but there is no need to create a wrapper
3508         for this operation, because 'Result is expanded independently
3509         when elaborating the postconditions.
3510
3511 2017-04-27  Bob Duff  <duff@adacore.com>
3512
3513         * sinput.adb: Minor code cleanup.
3514         * namet.adb (Append): Create faster versions of
3515         Append(String) and Append(Name_Id) by using slice assignment
3516         instead of loops.
3517         * sem_util.adb (In_Instance): Speed this up by removing
3518         unnecessary tests; Is_Generic_Instance is defined for all
3519         entities.
3520         * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3521         Remove unused function.
3522         * alloc.ads (Nodes_Initial): Use a much larger value, because
3523         the compiler was spending a lot of time copying the nodes table
3524         when it grows. This number was chosen in 1996, so is rather out
3525         of date with current memory sizes. Anyway, it's virtual memory.
3526         Get rid of Orig_Nodes_...; use Node_... instead.
3527         * atree.adb (Lock): Do not release the Nodes tables; it's a
3528         waste of time.
3529         Orig_Nodes_ ==> Nodes_
3530         * nlists.adb: Orig_Nodes_ ==> Nodes_
3531         * g-table.adb: Remove unused "with" clause.
3532         * g-table.ads, table.ads: Remove Big_Table_Type, which should
3533         not be used by clients.
3534         * g-dyntab.adb (Last_Allocated): New function
3535         to encapsulate T.P.Last_Allocated, which I'm thinking of changing.

3550         * exp_util.adb (Side_Effect_Free): Merge the processing for
3551         qualified expressions, type conversions, and unchecked type
3552         conversions.

3554         and Optional.

3558         for qualified expressions, type conversions, and unchecked
3559         type conversions.
3560         * sem_util.adb (Compile_Time_Constraint_Error): Merge the
3561         processing for Ada 83 and instances.
3562         (Object_Access_Level): Merge the processing for indexed components
3563         and selected components.
3564         * uname.adb (Add_Node_Name): Merge the processing for stubs.

3573
3574         * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
3575         of Expand_Dispatching_Call. If the denoted subprogram has a
3576         class-wide precondition, this is the only precondition that
3577         applies to the call, rather that the class-wide preconditions
3578         that may apply to the body that is executed. (This is specified
3579         in AI12-0195).
3580

3585         support IEEE-754 floats.
3586
3587 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
3588
3589         * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
3590         is itself inherited it does not carry any contract information,
3591         so examine its parent operation which is its Alias.
3592
3593 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
3594
3595         * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3596         prefix can be an object reference in which case Obj'Image (X)
3597         can only be interpreted as an indexing of the parameterless
3598         version of the attribute.
3599         * par-ch4.adb (P_Name): An attribute reference can be the prefix of
3600         an indexing or a slice operation if the attribute does not require
3601         parameters. In Ada2012 'Image also belongs in this category,
3602         and A'Image (lo .. hi) is legal and must be parsed as a slice.
3603
3604 2017-04-27  Yannick Moy  <moy@adacore.com>
3605
3606         * exp_ch4.adb: Minor reformatting.
3607         * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
3608         disable the CodePeer and C generation modes. Similar to the
3609         opposite actions done in CodePeer mode.
3610

3633         * g-dyntab.ads, g-dyntab.adb, g-table.ads: Remove incorrect assertion.
3634         If the table grows and then shrinks back to empty, we won't necessarily
3635         point back to the empty array. Code cleanups.
3636         * sinput.ads: Add 'Base to Size clause to match the declared
3637         component subtypes.

3735         * g-dyntab.ads, g-dyntab.adb: Misc cleanup. Rename
3736         Table_Count_Type --> Table_Last_Type, because the name

3794         operation whose ancestor has classwide pre/postconditions. This
3795         is used both to check the legality of the inheritance in Ada
3796         and in SPARK, and to determine whether a wrapper is needed for
3797         an inherited operation.

3949         class-wide clone of a subprogram with classwide conditions. The

3951         clone. The inherited operation becomes a similar wrapper to which
3952         modified conditions apply, and the call to the clone includes
3953         the proper conversion in a call the parent operation.

3966         and rewrite original body as a wrapper as a wrapper for a call to

3968         of the subprogram.
3969         * freeze.adb (Check_Inherited_Conditions): For an inherited
3970         subprogram that inherits a classwide condition, build spec and
3971         body of corresponding wrapper so that call to inherited operation
3972         gets the modified conditions.
3973         * contracts.adb (Analyze_Contracts): If analysis of classwide
3974         condition has created a clone for a primitive operation, analyze

4160         * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4161         to improve readablity. Subprograms are separated between basic
4162         operations, constructors and properties. Universally quantified
4163         formulas in contracts are factorized in independant functions
4164         with a name and a comment.  Names of parameters are improved.

4173         install a predicate check here since this is already done during
4174         the expansion phase. Verify whether the operand satisfies the
4175         static predicate (if any) of the target type.
4176         * sem_ch3.adb (Analyze_Object_Declaration): Do
4177         not install a predicate check if the object is initialized by
4178         means of a type conversion because the conversion is subjected
4179         to the same check.

4199
4200         * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4201         the loop which detects potential enclosing transient scopes. The
4202         loop now terminates much earlier as transient scopes are bounded
4203         by packages and subprograms.

4210         model functions.
4211         (Formal_Model): Ghost package containing
4212         model functions that are used in subprogram contracts.
4213         (Current_To_Last): Removed, model functions should be used
4214         instead.

4218         should be used instead.
4219         (Append): Default parameter value
4220         replaced by new wrapper to allow more precise contracts.

4260 2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>
4261
4262         * debug.adb Change the documentation of switch -gnatd.s.
4263         * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4264         to manage the secondary stack when an enclosing scope already
4265         performs this functionality (aka relaxed management). Switch
4266         -gnatd.s may be used to force strict management in which case
4267         the block will manage the secondary stack unconditionally. Add
4268         a guard to stop the traversal when encountering a package or a
4269         subprogram scope.
4270
4271 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
4272
4273         * sem_res.adb (Resolve_Call): Refine further the handling of
4274         limited views of return types in function calls. If the function
4275         that returns a limited view appears in the current unit,
4276         we do not replace its type by the non-limited view because
4277         this transformation is performed int the back-end. However,
4278         the type of the call itself must be the non-limited view, to
4279         prevent spurious resolution errors.
4280

4284         Removed, proposed implementation using generics for class-wide
4285         preconditions proved impractical.
4286         (Class_Wide_Clone): New attribute of subprogram. Designates
4287         subprogram created for primitive operations with class-wide
4288         pre/postconditions that contain calls to other primitives. The
4289         clone holds the body of the original primitive, but the
4290         pre/postonditions do not apply to it. The original body is
4291         rewritten as a wrapper for a call to the clone.
4292         (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4293         the flag is set, no code for the corresponding pre/postconditions
4294         is inserted into its body.

4483         it is used only in the body and in children.  Use trickery to

4505         Remove variants that include a Supress parameter. These routines

4562         eventually need to eliminate them altogether. Or else get rid
4563         of zero-origin addressing.

5364
5365         * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5366         Minor reformatting.
5367
5368 2017-04-25  Bob Duff  <duff@adacore.com>
5369
5370         * sem_prag.adb (No_Return): Give an error if the pragma applies
5371         to a body. Specialize the error for the specless body case,
5372         as is done for (e.g.) pragma Convention.
5373         * debug.adb: Add switch -gnatd.J to disable the above legality
5374         checks. This is mainly for use in our test suite, to avoid
5375         rewriting a lot of illegal (but working) code.  It might also
5376         be useful to customers. Under this switch, if a pragma No_Return
5377         applies to a body, and the procedure raises an exception (as it
5378         should), the pragma has no effect. If the procedure does return,
5379         execution is erroneous.
5380
5381 2017-04-25  Bob Duff  <duff@adacore.com>
5382
5383         * exp_ch6.adb (Expand_Actuals): This is the
5384         root of the problem. It took N as an 'in out' parameter, and in
5385         some cases, rewrote N, but then set N to Original_Node(N). So
5386         the node returned in N had no Parent. The caller continued
5387         processing of this orphaned node. In some cases that caused a
5388         crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5389         and trips over the Empty Parent). The solution is to make N an
5390         'in' parameter.  Instead of rewriting it, return the list of
5391         post-call actions, so the caller can do the rewriting later,
5392         after N has been fully processed.
5393         (Expand_Call_Helper): Move most of Expand_Call here. It has
5394         too many premature 'return' statements, and we want to do the
5395         rewriting on return.
5396         (Insert_Post_Call_Actions): New procedure to insert the post-call
5397         actions in the appropriate place. In the problematic case,
5398         that involves rewriting N as an Expression_With_Actions.
5399         (Expand_Call): Call the new procedures Expand_Call_Helper and
5400         Insert_Post_Call_Actions.

5411         support for renamings and functions that return a constrained
5412         array type (i.e. functions for which the frontend built a
5413         procedure with an extra out parameter).

5433         * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5434         convention Stdcall, which has a number of exceptions. Convention
5435         is legal on a component declaration whose type is an anonymous
5436         access to subprogram.

5470 2017-04-25  Bob Duff  <duff@adacore.com>
5471
5472         * s-fileio.adb (Close): When a temp file is
5473         closed, delete it and clean up its Temp_File_Record immediately,
5474         rather than waiting until later.
5475         (Temp_File_Record): Add File
5476         component, so Close can know which Temp_File_Record corresponds
5477         to the file being closed.
5478         (Delete): Don't delete temp files,
5479         because they are deleted by Close.
5480         (Open): Set the File component
5481         of Temp_File_Record. This requires moving the creation of the
5482         Temp_File_Record to the end, after the AFCB has been created.

5510         * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5511         conversions from float to integer in GNATprove mode.
5512         (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5513         to call Apply_Type_Conversion_Checks, so that range checks
5514         are properly positioned when needed on conversions, including
5515         when converting from float to integer.  (Determine_Range): In
5516         GNATprove mode, take into account the possibility of conversion
5517         from float to integer.
5518         * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5519         check on conversions from fixed-point to integer, not anymore

5559         Analyze_Pre_Post_Condition, to implement the legality checks
5560         mandated by AI12-0131: Pre'Class shall not be specified for an

5565 2017-04-25  Bob Duff  <duff@adacore.com>
5566
5567         * sem_ch8.adb (Use_One_Type): If a use_type_clause
5568         is redundant, set its Used_Operations to empty. This is only
5569         necessary for use clauses that appear in the parent of a generic
5570         child unit, because those use clauses get reanalyzed when we
5571         instantiate the generic, and we don't want the Used_Operations
5572         carried over from the original context (where it was probably
5573         not redundant).

5584         (Current_Sem_Unit) to find the correct casing.
5585         * par.adb (Par): Null out Current_Source_File, to ensure that

5604         Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a

5617         the operation out-of-line if the concatenation is present within

5619         not only if it is the expression of the declaration.

5624         not Remove_Side_Effects if there is a pragma Linker_Section,

5635         handle the proposed changes to rules concerning potentially
5636         unevaluated expressions, to include selected components that
5637         do not depend on discriminants, and indexed components with

5698         * a-numaux-x86.adb (Is_Nan): Minor tweak.
5699         (Reduce): Adjust and complete description. Call Is_Nan instead of
5700         testing manually. Use an integer temporary to hold rounded value.

5707         on analysis of prefix whose type is a current instance of a

5712
5713         * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5714         the identity of callable entities therein, because they have been

5716         as normal calls.

5747         Stop. Was using Current_Source_File, which is only valid during
5748         parsing. Current_Source_File will have a leftover value from
5749         whatever file happened to be parsed last, because of a with_clause

5757         with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5758         because Should_Ignore_Pragma was not working reliably outside
5759         the parser, because Current_Source_File is not valid.
5760         * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.

5831         of prefix whose type is a current instance of a synchronized
5832         type. If the prefix is an object this is an external call (or
5833         requeue) that can only access public operations of the object. The
5834         previous predicate was too restrictive, and did not allow public
5835         protected operations, only task entries.

5853         * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5854         * par-prag.adb Pragma No_Heap_Finalization does not need special
5855         processing from the parser.
5856         * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5857         ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5858         * sem_prag.adb Add an entry in table Sig_Flags for pragma
5859         No_Heap_Finalization.
5860         (Analyze_Pragma): Add processing for
5861         pragma No_Heap_Finalization. Update various error messages to
5862         use Duplication_Error.
5863         * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5864         * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5865         and corresponding pragma id.
5866
5867 2017-04-25  Bob Duff  <duff@adacore.com>
5868
5869         * freeze.adb (Freeze_Record_Type): Use the
5870         underlying type of the component type to determine whether it's
5871         elementary. For representation clause purposes, a private type
5872         should behave the same as its full type.
5873         * fname.ads, fname.adb (Is_Predefined_File_Name):
5874         Make sure things like "system.ali" are recognized as predefined.
5875
5876 2017-04-25  Javier Miranda  <miranda@adacore.com>
5877
5878         * debug.adb: Update documentation of -gnatd.6.
5879
5880 2017-04-25  Ed Schonberg  <schonberg@adacore.com>
5881
5882         * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5883         element iterator when the name is an overloaded function call,
5884         one of whose interpretations yields an array.
5885
5886 2017-04-25  Bob Duff  <duff@adacore.com>
5887
5888         * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5889         Is_Internal_Unit_Name): New functions for operating on unit
5890         names, as opposed to file names. There's some duplicated code
5891         with fname.adb, which is unfortunate, but it seems like we don't
5892         want to add dependencies here.
5893         * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5894         to Is_Predefined_Unit_Name; the former was wrong, because Uname
5895         is not a file name at all.
5896         * fname.ads, fname.adb: Document the fact that
5897         Is_Predefined_File_Name and Is_Internal_File_Name can be called
5898         for ALI files, and fix the code so it works properly for ALI
5899         files. E.g. these should return True for "system.ali".

5902
5903         * exp_util.adb (Add_Invariant): Removed,

5906         for adding runtime checks from any kind of invariant.
5907         (Add_Inherited_Invariant): Generates invariant checks for
5908         class-wide invariants (Add_Interface_Invariants): Removed, code
5909         moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5910         Create a types own invariant procedure (Add_Parent_Invariants):
5911         Removed, code moved to Build_Invariant_Procedure_Body
5912         (Build_Invariant_Procedure_Body): Add refactored calls
5913         and integrated code from Add_Parent_Invariants and
5914         Add_Interface_Invariants.
5915         (Process_Type): Removed, the
5916         relavant code was inlined into both Add_Own_Invariant and
5917         Add_Inherited_Invariant.

5933         an expression function.
5934
5935 2017-04-25  Justin Squirek  <squirek@adacore.com>
5936
5937         * exp_ch7.adb, exp_ch7.ads Remove Build_Invariant_Procedure_Body
5938         and Build_Invariant_Procedure_Declaration.
5939         * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5940         and Build_Invariant_Procedure_Declaration from exp_ch7
5941         and break-out Is_Untagged_Private_Derivation from
5942         Build_Invariant_Procedure_Body.
5943         (Replace_Type_References):
5944         Append an extra parameter to allow for dispatching replacements
5945         and add the corrasponding logic.
5946         (Type_Invariant): Remove
5947         Replace_Typ_Refs and replace its references with calls to
5948         Replace_Type_References.
5949         * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5950
5951 2017-04-25  Bob Duff  <duff@adacore.com>
5952
5953         * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5954         that returns True when appropriate.
5955         * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5956         when compiling predefined files.
5957         * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5958         "gnat.adc" should not be considered a predefined file name.
5959         That required (or at least encouraged) a lot of cleanup of global
5960         variable usage. We shouldn't be communicating information via
5961         the global name buffer.
5962         * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,

5994         * par-ch2.adb, scans.ads, scn.adb: Do not give an error for

5996         pragma name Interface to be used in pragma Ignore_Pragma.
5997         * par.adb: Minor comment fix.
5998

6023         the first pass over an assignment statement with target names,
6024         to prevent the generation of subtypes (such as discriminated
6025         record components)that may carry the target name outside of the
6026         tree for the assignment. The subtypes will be generated when
6027         the assignment is reanalyzed in full.
6028         (Analyze_Target_Name): Handle properly class-wide types.
6029

6037         (Add_Inherited_Tagged_DIC): There is really no need to preanalyze
6038         and resolve the triaged expression because all substitutions
6039         refer to the proper entities.  Update the replacement of
6040         references.
6041         (Build_DIC_Procedure_Body): Add formal parameter
6042         For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6043         are now only processed when freezing occurs.  Build a body only
6044         when one is needed.
6045         (Entity_Hash): Removed.

6060         properties of the private type to the full view in case the full
6061         view derives from a parent type and inherits a DIC pragma.
6062         * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6063         DIC pragma is placed at the top of a declarative region.

6073         the error message when the attribute reference is an actual in
6074         a call to a subprogram inherited from a generic formal type with
6075         unknown discriminants, which makes the subprogram and its formal
6076         parameters intrinsic (see RM 6.3.1 (8) and (13)).

6083 2017-04-25  Bob Duff  <duff@adacore.com>
6084
6085         * sem_attr.adb (Type_Key): Add code in the
6086         recursive Compute_Type_Key to protect against fetching the source
6087         code for Standard, in case a component of the type is declared
6088         in Standard. There was already code to do this for the original

6108         appears in the context of a unit U2 compiled for instantiation
6109         or inlining purposes, the body of U1 needs to be compiled as well.

6198         type map used in class-wide semantics of assertion expressions.
6199         (Add_Inherited_Tagged_DIC): There is really no need to preanalyze
6200         and resolve the triaged expression because all substitutions
6201         refer to the proper entities.  Update the replacement of
6202         references.
6203         (Build_DIC_Procedure_Body): Add formal parameter
6204         For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6205         are now only processed when freezing occurs.  Build a body only
6206         when one is needed.

6246         be constructed for an inherited primitive whose inherited
6247         pre/postcondition has called to overridden primitives.
6248         * freeze.adb (Check_Inherited_Conditions): Build wrapper body
6249         for inherited primitive that requires it.
6250         * sem_disp.adb (Check_Dispatching_Operation): Such wrappers are
6251         legal primitive operations and belong to the list of bodies
6252         generated after the freeze point of a type.
6253         * sem_prag.adb (Build_Pragma_Check_Equivalent): Use new signature

6273         and constrained parent discriminants, when the type to be
6274         constrained has fewer discriminants that the ultimate ancestor.

6306         * sem_util.adb (New_Copy_Tree): By default
6307         copying of defining identifiers is prohibited because
6308         this would introduce an entirely new entity into the
6309         tree. This patch introduces an exception to this general
6310         rule: the declaration of constants and variables located in
6311         Expression_With_Action nodes.
6312         (Copy_Itype_With_Replacement): Renamed as Copy_Entity_With_Replacement.

6785         of those globals. One the matching phase has completed,
6786         remove certain classes of clauses which are considered noise.

6853         an object declaration for an array type with a modular index type
6854         with the size of Long_Long_Integer. Special processing is needed
6855         in this case to compute reliably the size of the object, and

6868         component, avoid doing so if the call is to an instance of
6869         Unchecked_Conversion. Otherwise, the compiler turns it into an
6870         indexed component, and resolution of that turns it back into a

7231         * sem_aggr.adb (Resolve_Aggregate): If the type is a string
7232         type, ie. a type whose component is a character type, and the
7233         aggregate is positional, do not convert into a string literal
7234         if the index type is not an integer type, because the original
7235         type may be required in an enclosing operation.

7252         now done by Analyze_Declarations.
7253         * sem_disp.adb (Check_Dispatching_Operation): DIC and Invariant

7287         initialization of the object is performed by means of individual
7288         statements (and hence it must be done before the call).

7293         (Build_Derived_Enumeration_Type): If the derived type inherits a
7294         dynamic predicate from its parent, the bounds of the type must
7295         freeze because an explicit constraint is constructed for the
7296         type and the corresponding range is elaborated now.

7348         * binderr.ads (Errors_Detected, Warnings_Detected): Declare

7385         as a parameterless function call, but none of the candidate
7386         interpretations is parameterless, and there is a hidden homonym
7387         of the prefix that is a package.
7388         * sem_ch8.adb (Find_Selected_Component): If the prefix might be

7407         generic subprograms and packages; also, iteration over case
7408         statement alternatives rewritten to avoid testing if the first
7409         alternative is present (since it must be present due to Ada

7426         dimensionality check within an inlined body which inclddes both
7427         original operands and rewritten operands. This removes spurious
7428         dimensionality errors in the presence of front-end inlining,
7429         as well as in SPARK mode.

7550         that is expected to cause fewer ABE issues. This is a work in
7551         progress. The new algorithm is currently disabled, and can be
7552         enable by the -dp switch, or by modifying the Do_Old and Do_New
7553         etc. flags and rebuilding. Experimental code is included to
7554         compare the results of the old and new algorithms.
7555         * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7556         can have multiple of these tables, so the old and new algorithms
7557         can coexist.
7558         * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7559         parameter of type array. This avoids the global variable, and
7560         allows bounds checking (which is normally defeated by the tables

7566         switch.
7567         * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7568         and Bindgen.  Move writing of closure (-R and -Ra switches)

7572
7573         * sem_ch6.adb (Analyze_Expression_Function): If the expression
7574         function is a completion, all entities referenced in the
7575         expression are frozen. As a consequence, a reference to an
7576         uncompleted private type from an enclosing scope is illegal.

7579
7580         * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7581         (Analyze_Subprogram_Body_Helper): At the occurrence of an
7582         expression function declaration that is a completion, its
7583         expression causes freezing (AI12-0103).
7584
7585 2017-01-13  Vadim Godunko  <godunko@adacore.com>
7586

7605
7606         * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
7607         the legality of An others clause applies as well to a choice in
7608         an Iterated_component_ association.
7609         (Resolve_Iterated_Component_Association): An others choice
7610         is legal.
7611         * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An

7642         (Gen_Loop): Generate proper loop for an
7643         Iterated_Component_Association: loop variable has the identifier
7644         of the original association. Generate a loop even for a single
7645         component choice, in order to make loop parameter visible in
7646         expression.
7647         (Flatten): An Iterated_Component_Association is not static.
7648
7649 2017-01-13  Yannick Moy  <moy@adacore.com>
7650
7651         * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7652         float exponentiation for statically known small negative values
7653         is the reciprocal of the exponentiation for the opposite value
7654         of the exponent.
7655         * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
7656         Ensure that the value of float exponentiation for negative values
7657         is the reciprocal of the exponentiation for the opposite value
7658         of the exponent.
7659         * inline.adb (Expand_Inlined_Call): Fix the count
7660         for the number of generated gotos.
7661
7662 2017-01-13  Yannick Moy  <moy@adacore.com>
7663

7667
7668 2017-01-13  Ed Schonberg  <schonberg@adacore.com>
7669
7670         * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7671         mode a choice that is a subtype with a static predicate is
7672         replaced by the values it covers. This transformation must not
7673         be performed in ASIS mode, to preserve the source for analysis.
7674
7675 2017-01-13  Justin Squirek  <squirek@adacore.com>
7676
7677         * nlists.ads: Correct minor typo.

7679 2017-01-13  Gary Dismukes  <dismukes@adacore.com>

7684
7685         * par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
7686         Iterated_Component_Association is a named association in an
7687         array aggregate.
7688         * sem_aggr.adb (Resolve_Iterated_Component_Association): New
7689         procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7690         and resolve the discrete choices and the expression of the
7691         new construct.
7692         * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7693         Loop_Actions and Box_Present are attributes of
7694         N_Iterated_Component_Association nodes. Box_Present is always
7695         False in this case.
7696         * sprint.adb (Sprint_Node): An Iterated_Component_Association
7697         has a Discrete_Choices list, as specified in the RM. A
7698         Component_Association for aggregate uses instead a Choices list.
7699         We have to live with this small inconsistency because the new
7700         construct also has a defining identifier, and there is no way
7701         to merge the two node structures.
7702
7703 2017-01-13  Yannick Moy  <moy@adacore.com>
7704

7710 2017-01-13  Ed Schonberg  <schonberg@adacore.com>
7711
7712         * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
7713         Analyze_Declarations, to analyze and resolve the expressions of
7714         aspect specifications in the current declarative list, so that
7715         the expressions have proper entity and type info.  This is needed
7716         for ASIS when there is no subsequent expansion to generate this
7717         semantic information.
7718         * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7719         original expression, to suppress cascaded errors when expression
7720         has been constant-folded.
7721         (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7722         ASIS mode, because there is no subsequent expansion to decorate
7723         the tree.
7724
7725 2017-01-13  Yannick Moy  <moy@adacore.com>
7726
7727         * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
7728         New function to detect when a call may be inlined or not in
7729         GNATprove mode.
7730         (Expand_Inlined_Call): Ensure that a temporary
7731         is always created in the cases where a type conversion may be
7732         needed on an input parameter in GNATprove mode, so that GNATprove
7733         sees the check to perform.
7734         * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7735         when not applicable due to actual requiring type conversion
7736         with possible check but no temporary value can be copied for
7737         GNATprove to see the check.

8837         body entity.
8838         * exp_ch6.adb (Expand_Protected_Subprogram_Call): if the call is
8839         within an Entry_Wrapper this is an external call whose target
8840         is the synchronized object that is the actual in the call to
8841         the wrapper.
8842

8869         If expression is compile-time known and obeys a static predicate
8870         it must be labelled as static, to prevent spurious warnings and
8871         run-time errors, e.g. in case statements. This is relevant when
8872         the expression is the result of constant-folding a type conversion
8873         whose expression is a variable with a known static value.

8911 2017-01-06  Ed Schonberg  <schonberg@adacore.com>
8912
