430 * sem_util.adb (Requires_Transient_Scope): For definite untagged
431 subtypes, we should never have to use the secondary stack. This moves
432 toward that goal. But there are still cases that don't work.
433 Here, we move the check for Is_Definite first, but add a
434 special-purpose check for Has_Discrim_Dep_Array.

448 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
449 names in named associations only needs to be done within an
450 instance, on a call to a primitive of a formal derived type,
451 where the actual subprogram may have different formal names than
452 those of the primitive operation of the formal type.
453 b) Defaulted parameters must be taken into account when obtaining
454 the names of the formals of the actual subprogram being called.

468 * exp_tss.ads: Minor comment fix.
469 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
470 Inline init_procs when the type has controlled parts. Remove
471 obsolete comments about those init_procs -- init_procs for
472 such types are no longer complex. A typical init_proc just
473 initializes the 'Tag field, and calls the parent init_proc
474 (e.g. for Limited_Controlled), which calls the grandparent
475 (for Root_Controlled), which does nothing. This all boils down
476 to one instruction when inlined.
477 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
479 2015-05-28 Ed Schonberg <schonberg@adacore.com>
481 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
482 is a derived type and is a generic actual, the selected component
483 appears within an instance body, and the check over the type
484 has failed, examine ancestor types for the desired component.
485 (Find_Component_In_Instance): If record type is a derived type,

496 comes from the main unit.
498 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
500 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
501 code applying atomic checks to the object.
503 2015-05-27 Robert Dewar <dewar@adacore.com>

516 opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
517 sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.

521 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
522 well as kernel.
524 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
526 * par_sco.adb (Process_Decision): Store sloc to
527 condition/pragmas SCOs associations into a temporary table before
528 moving them to the SCO_Raw_Hash_Table so that we can back them
529 out just like we do for SCO entries that are simple decisions
530 in an expression context.
532 2015-05-27 Ed Schonberg <schonberg@adacore.com>
534 * sem_ch6.adb (Process_Formals): A non-private formal type that

537 2015-05-27 Ed Schonberg <schonberg@adacore.com>
539 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
540 the case statement is a compile-time known value, we look for a
541 corresponding alternative to optimize the case statement into a
542 single case. If the type has a static predicate and the expression
543 does not satisfy the predicate, there is no legal alternative and
544 this optimization is not applicable. Excecution is erroneous,
545 or else if assertions are enabled, an exception will be raised
546 earlier, at the point the expression is elaborated.
548 2015-05-27 Robert Dewar <dewar@adacore.com>

563 2015-05-26 Bob Duff <duff@adacore.com>
565 * sem_elab.adb (Check_A_Call): In the case where we're
566 calling something in an instance of a generic package that is
567 within this same unit (as the call), make sure we treat it
568 as a call to an entity within the same unit. That is, call
569 Check_Internal_Call, rather than putting "Elaborate_All(X)"
570 on X, which would necessarily result in an elaboration cycle in
571 static-elaboration mode.
573 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
575 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.

595 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
596 force evaluation of the expression, if any, when the object has its
597 elaboration delayed. Do not create a variable at global level.
599 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
601 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
602 extra-precision trick to literals. Build SAVE_EXPR manually.
604 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

622 pointers by renamed objects.
623 (outer_atomic_access_required_p): Deal with renamings.

644 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
645 to detect constant renamings. Be prepared for specific pattern of
646 renamed object based on function calls. Create a constant object
647 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
648 to gnat_stabilize_reference and tidy up. Remove redundant tests.

674 body. Remove useless freeze nodes for incomplete actuals to
675 prevent multiple generation of internal operations.

677 there are incomplete actuals and the instance body is placed in
678 the body of the enclosing unit.
679 * errout.ads: Consistent punctuation, better alignment and trivial
680 typos in comments.

701 2015-05-26 Ed Schonberg <schonberg@adacore.com>
703 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
704 of original expression in ASIS mode: does not solve the ASIS

706 when performing type annotations.
708 2015-05-26 Robert Dewar <dewar@adacore.com>
710 * sem_disp.adb (Inherited_Subprograms): Add One_Only parameter.

720 2015-05-26 Bob Duff <duff@adacore.com>
722 * treepr.adb: Minor improvement to debugging routines (pp, pn)
723 robustness. Rearrange the code so passing a nonexistent Node_Id
724 prints "No such node" rather than crashing, and causing gdb to
725 generate confusing messages.

964 sem_ch12.adb, sem_ch3.adb, sem_ch4.adb, sem_ch6.adb, sem_ch7.adb,
965 sem_util.adb: Change the sense of Is_Indefinite_Subtype to be
966 Is_Definite_Subtype. This is an improvement to readability (the double

1428 (Resolve_Record_Aggregate): Propagate the Check_Actuals flag to the
1429 internally built aggregate.
1430 * sem_ch3.adb (Build_Derived_Record_Type, Record_Type_Declaration):

1438 has out or in-out parameters then mark its outermost enclosing
1439 construct as a node on which the writable actuals check must
1440 be performed.

1442 enclosing construct.
1443 * sem_util.adb (Check_Function_Writable_Actuals): Code cleanup
1444 and reorganization. We skip processing aggregate discriminants
1445 since their precise analysis involves two phases traversal.

1463 * sem_res.adb (Resolve_Actuals): If the call is to an overridden
1464 operation, replace the names of the actuals in named associations
1465 with the names of the actuals of the subprogram that is eventually
1466 executed. The names of the formals and the defaults can differ
1467 between the two operations when they are operations of a formal
1468 derived type.
1470 2015-05-22 Bob Duff <duff@adacore.com>
1472 * a-convec.ads, a-convec.adb (Append): Check for fast path. Split
1473 out slow path into separate procedure. Inline Append. Fast path
1474 now avoids calling Insert.
1475 (Finalize): Do the busy checking last, so the container gets emptied.
1476 (Insert, Insert_Space): Remove redundancy.
1478 2015-05-22 Robert Dewar <dewar@adacore.com>
1480 * switch-c.adb (Scan_Front_End_Switches): Insist on -gnatc

1494 Limited_With.
1495 * sem_ch10.adb: Minor reformatting.

1505 * exp_aggr.adb (Get_Constraint_Association): If type (of ancestor
1506 composite type) is private, go to full view. This was previously

1524 declarations added for use by performance improvements in exp_ch5.adb.
1525 * snames.ads-tmpl: New names referenced by exp_ch5.adb.
1526 * exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
1527 Instead of doing literally what the RM calls for, we do something
1528 equivalent that avoids expensive operations inside the loop. If the
1529 container package has appropriate Next, Pseudo_Reference,
1530 Element_Access, Get_Element_Access declarations, we invoke the
1531 optimization.
1532 * snames.ads-tmpl: Note speed improvement.

1639 actuals of instance, for later placement of instance body and
1640 freeze nodes for actuals.
1641 (Install_Body): In the presence of actuals that incomplete types
1642 from a limited view, the instance body cannot be placed after
1643 the declaration because full views have not been seen yet. Any
1644 use of the non-limited views in the instance body requires
1645 the presence of a regular with_clause in the enclosing unit,
1646 and will fail if this with_clause is missing. We place the
1647 instance body at the beginning of the enclosing body, which is
1648 the unit being compiled, and ensure that freeze nodes for the
1649 full views of the incomplete types appear before the instance.

2440 to Freeze_Entity. In addition to the previous processing steps
2441 at the freeze point of an object, this procedure also handles

2465 incomplete class-wide type, the subprogram must have a delayed
2466 freeze even though the opertation is not a primitive of the

2496 an unconstrained synchronized type with discriminants, create a
2497 constrained default subtype for it, so that the enclosing record
2498 can be given the proper size.
2499 * sem_util.adb (Build_Default_Subtype): If the subtype is created
2500 for a record discriminant, do not analyze the declarztion at
2501 once because it is added to the freezing actions of the enclosing
2502 record type.

3178 expanding a 'Input attribute reference for a class-wide type,
3179 do not generate a separate object declaration for the controlling
3180 tag dummy object; instead, generate the expression inline in the

3182 call to String'Input, returning a dynamically sized value on the
3183 secondary stack) will be expanded outside of proper secondary
3184 stack mark/release operations, and will thus cause a secondary
3185 stack leak.

5112 point types.
5113 * set_targ.adb (Long_Double_Index): The index at which "long
5114 double" gets registered in the FPT_Mode_Table. This is useful to

5127 (elaboration code): Register_Back_End_Types unconditionally,
5128 so C_Type_For can operate regardless of -gnateT. Do it
5129 early so we can query it for the floating point sizes, via

5131 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
5132 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
5133 which C type should be used as the basis for the construction
5134 of the Standard Ada floating point types.

5154 has been resolved, and replace the standard renaming declaration
5155 with the declaration of wrapper.

5291 2015-01-06 Javier Miranda <miranda@adacore.com>
5293 * exp_disp.adb (Expand_Interface_Conversion): No displacement
5294 of the pointer to the object needed when the type of the operand
5295 is not an interface type and the interface is one of its parent
5296 types (since they share the primary dispatch table).
5298 2015-01-06 Vincent Celier <celier@adacore.com>
5300 * prj-env.adb: Minor comment update.
5302 2015-01-06 Javier Miranda <miranda@adacore.com>

5305 access types whose target type is an interface type to operands
5306 that are access types; required to report an error when the
5307 operand is not an access type.
5309 2015-01-06 Bob Duff <duff@adacore.com>
5311 * a-cfinve.adb (Copy): Set the discriminant to the Length when
5312 Capacity = 0.
5313 * a-cofove.ads (Capacity): Add a postcondition.
5314 * a-cfinve.ads (Capacity): Add a postcondition.

5320 2015-01-06 Ed Schonberg <schonberg@adacore.com>

5336 with the runtime name.
5337 * prj-env.adb (Initialize_Default_Project_Path): When both
5338 Target_Name and Runtime_Name are not empty string, add to the
5339 project path the two directories .../lib/gnat and .../share/gpr

5348 rewritten as a null statement.
5349 * sem_prag.adb (Analyze_Pragma): Insert a brand new Check_Policy
5350 pragma using Insert_Before rather than Insert_Action. This
5351 takes care of the configuration pragma case where Insert_Action
5352 would fail.

5356 * a-coboho.ads (Element_Access): Add "pragma
5357 No_Strict_Aliasing (Element_Access);". This is needed because

5360 result to be 1.
