465 those of the primitive operation of the formal type.
466 b) Defaulted parameters must be taken into account when obtaining
467 the names of the formals of the actual subprogram being called.

481 * exp_tss.ads: Minor comment fix.
482 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
483 Inline init_procs when the type has controlled parts. Remove
484 obsolete comments about those init_procs -- init_procs for
485 such types are no longer complex. A typical init_proc just
486 initializes the 'Tag field, and calls the parent init_proc
487 (e.g. for Limited_Controlled), which calls the grandparent
488 (for Root_Controlled), which does nothing. This all boils down
489 to one instruction when inlined.
490 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
492 2015-05-28 Ed Schonberg <schonberg@adacore.com>
494 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
495 is a derived type and is a generic actual, the selected component
496 appears within an instance body, and the check over the type
497 has failed, examine ancestor types for the desired component.
498 (Find_Component_In_Instance): If record type is a derived type,
499 examine all ancestors in order to locate desired component.

540 condition/pragmas SCOs associations into a temporary table before
541 moving them to the SCO_Raw_Hash_Table so that we can back them
542 out just like we do for SCO entries that are simple decisions
543 in an expression context.
545 2015-05-27 Ed Schonberg <schonberg@adacore.com>
547 * sem_ch6.adb (Process_Formals): A non-private formal type that

550 2015-05-27 Ed Schonberg <schonberg@adacore.com>
552 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
553 the case statement is a compile-time known value, we look for a
554 corresponding alternative to optimize the case statement into a
555 single case. If the type has a static predicate and the expression
556 does not satisfy the predicate, there is no legal alternative and
557 this optimization is not applicable. Excecution is erroneous,
558 or else if assertions are enabled, an exception will be raised
559 earlier, at the point the expression is elaborated.

576 2015-05-26 Bob Duff <duff@adacore.com>
578 * sem_elab.adb (Check_A_Call): In the case where we're
579 calling something in an instance of a generic package that is
580 within this same unit (as the call), make sure we treat it
581 as a call to an entity within the same unit. That is, call
582 Check_Internal_Call, rather than putting "Elaborate_All(X)"
583 on X, which would necessarily result in an elaboration cycle in
584 static-elaboration mode.
586 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
588 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.

608 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
609 force evaluation of the expression, if any, when the object has its
610 elaboration delayed. Do not create a variable at global level.
612 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
614 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
615 extra-precision trick to literals. Build SAVE_EXPR manually.
617 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

635 pointers by renamed objects.
636 (outer_atomic_access_required_p): Deal with renamings.

657 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
658 to detect constant renamings. Be prepared for specific pattern of

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

716 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
717 of original expression in ASIS mode: does not solve the ASIS

733 2015-05-26 Bob Duff <duff@adacore.com>
735 * treepr.adb: Minor improvement to debugging routines (pp, pn)
736 robustness. Rearrange the code so passing a nonexistent Node_Id

1096 Swap_Private_Dependents): Ensure that both views of the dependent
1097 subtype are immediately visible if we are within their scope. This
1098 may be needed when a procedure body is both the parent of an

1144 checks, that function call, though it is labelled Analyzed to
1145 prevent an infinite recursion, may be rewritten as a temporary
1146 by Remove_Side_Effects. Ensure that the caller has access to
1147 the original function call to continue expansion.

1261 stream operation. The attribute definition clause generated from
1262 the aspect will be inserted at the freeze point of the type,
1263 which may be in the private part and not directly visible,

1431 on entries, entry families, subprograms and generic subprograms.
1432 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration):
1433 Minor code reorganization to ensure that the Ekind attribute
1434 of the subprogram entity is set before its formals are
1435 processed. Required to allow the use of the attribute
1436 Has_Out_Or_In_Out_Parameter on the subprogram entity.
1437 * sem_aggr.adb (Resolve_Aggregate, Resolve_Extension_Aggregate):
1438 Perform the check on writable actuals only if the value of some
1439 component of the aggregate involves calling a function with
1440 out-mode parameters.
1441 (Resolve_Record_Aggregate): Propagate the Check_Actuals flag to the
1442 internally built aggregate.
1443 * sem_ch3.adb (Build_Derived_Record_Type, Record_Type_Declaration):

1450 (Analyze_Call.Check_Writable_Actuals): New subprogram. If the call
1451 has out or in-out parameters then mark its outermost enclosing
1452 construct as a node on which the writable actuals check must
1453 be performed.

1455 enclosing construct.
1456 * sem_util.adb (Check_Function_Writable_Actuals): Code cleanup
1457 and reorganization. We skip processing aggregate discriminants
1458 since their precise analysis involves two phases traversal.

1476 * sem_res.adb (Resolve_Actuals): If the call is to an overridden
1477 operation, replace the names of the actuals in named associations
1478 with the names of the actuals of the subprogram that is eventually
1479 executed. The names of the formals and the defaults can differ
1480 between the two operations when they are operations of a formal
1481 derived type.
1483 2015-05-22 Bob Duff <duff@adacore.com>
1485 * a-convec.ads, a-convec.adb (Append): Check for fast path. Split
1486 out slow path into separate procedure. Inline Append. Fast path
1487 now avoids calling Insert.
1488 (Finalize): Do the busy checking last, so the container gets emptied.
1489 (Insert, Insert_Space): Remove redundancy.
1491 2015-05-22 Robert Dewar <dewar@adacore.com>
1493 * switch-c.adb (Scan_Front_End_Switches): Insist on -gnatc

1506 * sinfo.ads (N_With_Clause): Add comment on handling of
1507 Limited_With.
1508 * sem_ch10.adb: Minor reformatting.

1514 because it is declared in a different unit.
1516 2015-05-22 Ed Schonberg <schonberg@adacore.com>
1518 * exp_aggr.adb (Get_Constraint_Association): If type (of ancestor
1519 composite type) is private, go to full view. This was previously

1536 (Pseudo_Reference, Element_Access, Get_Element_Access): New
1537 declarations added for use by performance improvements in exp_ch5.adb.
1538 * snames.ads-tmpl: New names referenced by exp_ch5.adb.
1539 * exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
1540 Instead of doing literally what the RM calls for, we do something
1541 equivalent that avoids expensive operations inside the loop. If the
1542 container package has appropriate Next, Pseudo_Reference,
1543 Element_Access, Get_Element_Access declarations, we invoke the
1544 optimization.
1545 * snames.ads-tmpl: Note speed improvement.
1547 2015-05-22 Eric Botcazou <ebotcazou@adacore.com>

1578 exp_ch4.adb, errout.adb, exp_aggr.adb, sem_ch13.adb: This is a general
1579 change that deals with the fact that most of the special coding for
1580 Atomic should also apply to the case of Volatile_Full_Access.
1581 A new attribute Is_Atomic_Or_VFA is introduced, and many of the
1582 references to Is_Atomic now use this new attribute.
1584 2015-05-22 Robert Dewar <dewar@adacore.com>
1586 * exp_ch4.adb (Expand_N_Op_Eq): Introduce 'Machine for 'Result

1628 for switch -P and, if found and gprclean is available, invoke
1629 silently gprclean.
1630 * make.adb (Initialize): For native gnatmake, check for switch -P
1631 and, if found and gprbuild is available, invoke silently gprbuild.

1651 * sem_ch12.adb (Preanalyze_Actuals): Build list of incomplete
1652 actuals of instance, for later placement of instance body and
1653 freeze nodes for actuals.
1654 (Install_Body): In the presence of actuals that incomplete types
1655 from a limited view, the instance body cannot be placed after
1656 the declaration because full views have not been seen yet. Any
1657 use of the non-limited views in the instance body requires
1658 the presence of a regular with_clause in the enclosing unit,
1659 and will fail if this with_clause is missing. We place the
1660 instance body at the beginning of the enclosing body, which is
1661 the unit being compiled, and ensure that freeze nodes for the
1662 full views of the incomplete types appear before the instance.

2453 to Freeze_Entity. In addition to the previous processing steps
2454 at the freeze point of an object, this procedure also handles

2478 incomplete class-wide type, the subprogram must have a delayed
2479 freeze even though the opertation is not a primitive of the

2512 * sem_util.adb (Build_Default_Subtype): If the subtype is created
2513 for a record discriminant, do not analyze the declarztion at
2514 once because it is added to the freezing actions of the enclosing
2515 record type.

3195 call to String'Input, returning a dynamically sized value on the
3196 secondary stack) will be expanded outside of proper secondary

3338 Initial_Condition, Initializes and Refined_State have been clean
3339 up. Pragmas Post, Post_Class, Postcondition, Pre, Pre_Class
3340 and Precondition now use the same routine for analysis. Pragma

5124 ttypes values and the GNAT tree nodes for the standard floating
5125 point types.
5126 * set_targ.adb (Long_Double_Index): The index at which "long
5127 double" gets registered in the FPT_Mode_Table. This is useful to
5128 know whether we have a "long double" available at all and get at

5138 suitable as a basis to construct the standard Ada floating point
5139 type identified by the input T parameter.
5140 (elaboration code): Register_Back_End_Types unconditionally,
5141 so C_Type_For can operate regardless of -gnateT. Do it
5142 early so we can query it for the floating point sizes, via

5144 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
5145 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
5146 which C type should be used as the basis for the construction
5147 of the Standard Ada floating point types.

5167 has been resolved, and replace the standard renaming declaration
5168 with the declaration of wrapper.

5170 make public for use elsewhere.
5171 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):

5214 last_entity may have been assigned already.
5216 2015-01-06 Ed Schonberg <schonberg@adacore.com>
5218 * sem_ch4.adb (Analyze_One_Call): If formal has an incomplete

5307 of the pointer to the object needed when the type of the operand
5308 is not an interface type and the interface is one of its parent
5309 types (since they share the primary dispatch table).

5319 that are access types; required to report an error when the
5320 operand is not an access type.
