360 2015-05-28 Ed Schonberg <schonberg@adacore.com>
362 * sem_ch3.adb (Is_Visible_Component): Component is visible
363 in a derived type if inherited through an ancestor that has a
364 partial view of the original type holding the component, if the
365 full view of that original type is in scope.
366 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
368 2015-05-28 Bob Duff <duff@adacore.com>
370 * sem_util.adb (Requires_Transient_Scope): For definite untagged
371 subtypes, we should never have to use the secondary stack. This moves
372 toward that goal. But there are still cases that don't work.
373 Here, we move the check for Is_Definite first, but add a
374 special-purpose check for Has_Discrim_Dep_Array.
376 2015-05-28 Bob Duff <duff@adacore.com>
378 * sem_util.adb (Requires_Transient_Scope): Avoid returning

386 2015-05-28 Ed Schonberg <schonberg@adacore.com>
388 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
389 names in named associations only needs to be done within an
390 instance, on a call to a primitive of a formal derived type,
391 where the actual subprogram may have different formal names than
392 those of the primitive operation of the formal type.
393 b) Defaulted parameters must be taken into account when obtaining
394 the names of the formals of the actual subprogram being called.
396 2015-05-28 Robert Dewar <dewar@adacore.com>
398 * sem_ch13.adb, sem_disp.ads: Minor reformatting.

406 2015-05-28 Bob Duff <duff@adacore.com>
408 * exp_tss.ads: Minor comment fix.
409 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
410 Inline init_procs when the type has controlled parts. Remove
411 obsolete comments about those init_procs -- init_procs for
412 such types are no longer complex. A typical init_proc just
413 initializes the 'Tag field, and calls the parent init_proc
414 (e.g. for Limited_Controlled), which calls the grandparent
415 (for Root_Controlled), which does nothing. This all boils down
416 to one instruction when inlined.
417 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
419 2015-05-28 Ed Schonberg <schonberg@adacore.com>
421 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
422 is a derived type and is a generic actual, the selected component
423 appears within an instance body, and the check over the type
424 has failed, examine ancestor types for the desired component.
425 (Find_Component_In_Instance): If record type is a derived type,
426 examine all ancestors in order to locate desired component.
428 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>
430 * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.
432 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>

462 well as kernel.
464 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
466 * par_sco.adb (Process_Decision): Store sloc to
467 condition/pragmas SCOs associations into a temporary table before
468 moving them to the SCO_Raw_Hash_Table so that we can back them
469 out just like we do for SCO entries that are simple decisions
470 in an expression context.
472 2015-05-27 Ed Schonberg <schonberg@adacore.com>
474 * sem_ch6.adb (Process_Formals): A non-private formal type that
475 is a limited view does not have a list of private dependents.
477 2015-05-27 Ed Schonberg <schonberg@adacore.com>
479 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
480 the case statement is a compile-time known value, we look for a
481 corresponding alternative to optimize the case statement into a
482 single case. If the type has a static predicate and the expression
483 does not satisfy the predicate, there is no legal alternative and
484 this optimization is not applicable. Excecution is erroneous,
485 or else if assertions are enabled, an exception will be raised
486 earlier, at the point the expression is elaborated.

503 2015-05-26 Bob Duff <duff@adacore.com>
505 * sem_elab.adb (Check_A_Call): In the case where we're
506 calling something in an instance of a generic package that is
507 within this same unit (as the call), make sure we treat it
508 as a call to an entity within the same unit. That is, call
509 Check_Internal_Call, rather than putting "Elaborate_All(X)"
510 on X, which would necessarily result in an elaboration cycle in
511 static-elaboration mode.
513 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
515 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.

562 pointers by renamed objects.
563 (outer_atomic_access_required_p): Deal with renamings.

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

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

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

646 when performing type annotations.
648 2015-05-26 Robert Dewar <dewar@adacore.com>
650 * sem_disp.adb (Inherited_Subprograms): Add One_Only parameter.

660 2015-05-26 Bob Duff <duff@adacore.com>
662 * treepr.adb: Minor improvement to debugging routines (pp, pn)
663 robustness. Rearrange the code so passing a nonexistent Node_Id

665 generate confusing messages.
667 2015-05-26 Gary Dismukes <dismukes@adacore.com>

905 sem_util.adb: Change the sense of Is_Indefinite_Subtype to be
906 Is_Definite_Subtype. This is an improvement to readability (the double

1071 checks, that function call, though it is labelled Analyzed to
1072 prevent an infinite recursion, may be rewritten as a temporary
1073 by Remove_Side_Effects. Ensure that the caller has access to
1074 the original function call to continue expansion.

1188 stream operation. The attribute definition clause generated from
1189 the aspect will be inserted at the freeze point of the type,
1190 which may be in the private part and not directly visible,

1445 * exp_aggr.adb (Get_Constraint_Association): If type (of ancestor

1467 Instead of doing literally what the RM calls for, we do something
1468 equivalent that avoids expensive operations inside the loop. If the
1469 container package has appropriate Next, Pseudo_Reference,
1470 Element_Access, Get_Element_Access declarations, we invoke the
1471 optimization.
1472 * snames.ads-tmpl: Note speed improvement.

1579 actuals of instance, for later placement of instance body and
1580 freeze nodes for actuals.
1581 (Install_Body): In the presence of actuals that incomplete types
1582 from a limited view, the instance body cannot be placed after
1583 the declaration because full views have not been seen yet. Any
1584 use of the non-limited views in the instance body requires
1585 the presence of a regular with_clause in the enclosing unit,
1586 and will fail if this with_clause is missing. We place the
1587 instance body at the beginning of the enclosing body, which is
1588 the unit being compiled, and ensure that freeze nodes for the
1589 full views of the incomplete types appear before the instance.

2377 expression when the object declaration carries aspects Address
2378 and/or Alignment.
2379 * freeze.adb (Freeze_Object_Declaration): New subsidiary procedure
2380 to Freeze_Entity. In addition to the previous processing steps
2381 at the freeze point of an object, this procedure also handles
2382 aggregates in object declarations, when the declaration carries

2384 object be attached to its freeze actions.

2405 incomplete class-wide type, the subprogram must have a delayed
2406 freeze even though the opertation is not a primitive of the

2439 * sem_util.adb (Build_Default_Subtype): If the subtype is created
2440 for a record discriminant, do not analyze the declarztion at

2901 * exp_ch7.adb (Make_Set_Finalize_Address_Call): Use underlying
2902 type to retrieve designated type, because the purported access
2903 type may be a partial (private) view, when it is declared in

3118 expanding a 'Input attribute reference for a class-wide type,
3119 do not generate a separate object declaration for the controlling
3120 tag dummy object; instead, generate the expression inline in the
3121 dispatching call. Otherwise, the declaration (which involves a
3122 call to String'Input, returning a dynamically sized value on the
3123 secondary stack) will be expanded outside of proper secondary
3124 stack mark/release operations, and will thus cause a secondary
3125 stack leak.

5051 ttypes values and the GNAT tree nodes for the standard floating
5052 point types.
5053 * set_targ.adb (Long_Double_Index): The index at which "long
5054 double" gets registered in the FPT_Mode_Table. This is useful to

5067 (elaboration code): Register_Back_End_Types unconditionally,
5068 so C_Type_For can operate regardless of -gnateT. Do it
5069 early so we can query it for the floating point sizes, via

5071 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
5072 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
5073 which C type should be used as the basis for the construction
5074 of the Standard Ada floating point types.

5094 has been resolved, and replace the standard renaming declaration
5095 with the declaration of wrapper.

5097 make public for use elsewhere.
5098 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):

5280 related to the runtime.
5281 * prj-env.ads (Initialize_Default_Project_Path): New String
5282 parameter Runtime_Name, defaulted to the empty string.

5286 * frontend.adb: Guard against the case where a configuration
5287 pragma may be split into multiple pragmas and the original
5288 rewritten as a null statement.
5289 * sem_prag.adb (Analyze_Pragma): Insert a brand new Check_Policy
5290 pragma using Insert_Before rather than Insert_Action. This
5291 takes care of the configuration pragma case where Insert_Action
5292 would fail.
5294 2015-01-06 Bob Duff <duff@adacore.com>
5296 * a-coboho.ads (Element_Access): Add "pragma
5297 No_Strict_Aliasing (Element_Access);". This is needed because
5298 we are unchecked-converting from Address to Element_Access.
5299 * a-cofove.ads, a-cofove.adb (Elems,Elemsc): Fix bounds of the
5300 result to be 1.

5304 * sem_res.adb (Resolve_Actuals): Remove the

5306 enabled external propery Async_Writers to act appear in procedure
5307 calls where the corresponding formal is of mode OUT.
5309 2015-01-05 Jakub Jelinek <jakub@redhat.com>
5311 * gnat_ugn.texi: Bump @copying's copyright year.

5316 * gcc-interface/Makefile.in (../stamp-tools): Reinstate dropped code.
5318 2015-01-04 Uros Bizjak <ubizjak@gmail.com>
