242 * gcc-interface/utils.c (gnat_pushdecl): Reunify the handling of array
243 and pointer types wrt DECL_ORIGINAL_TYPE and adjust left and right.
245 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
247 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust.
248 (rewrite_fn): Remove third parameter.

253 (cannot_be_superflat ): ...this.
254 (initial_value_needs_conversion): New predicate.
255 (gnat_to_gnu_entity): Invoke type_is_padding_self_referential,
256 initial_value_needs_conversion and adjust to above renaming.

259 compound expression if needed.
260 (struct er_dat): Add N field.
261 (elaborate_reference_1): Remove N parameter and adjust.
262 (elaborate_reference): Add INIT parameter and pass it in the call to

267 if needed. Invoke return_type_with_variable_size_p.
268 (gnat_to_gnu): Invoke type_is_padding_self_referential. In case #4,
269 return a call to a function unmodified if it returns with variable size
270 and is also the initial expression in an object declaration.
271 * gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: Use the RHS'
272 type if it is a call to a function that returns with variable size.
273 (build_unary_op): Invoke type_is_padding_self_referential.

278 <COMPOUND_EXPR>: New case.
280 2015-05-28 Ed Schonberg <schonberg@adacore.com>
282 * sem_ch3.adb (Is_Visible_Component): Component is visible
283 in a derived type if inherited through an ancestor that has a
284 partial view of the original type holding the component, if the
285 full view of that original type is in scope.
286 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
288 2015-05-28 Bob Duff <duff@adacore.com>
290 * sem_util.adb (Requires_Transient_Scope): For definite untagged
291 subtypes, we should never have to use the secondary stack. This moves
292 toward that goal. But there are still cases that don't work.
293 Here, we move the check for Is_Definite first, but add a
294 special-purpose check for Has_Discrim_Dep_Array.
296 2015-05-28 Bob Duff <duff@adacore.com>
298 * sem_util.adb (Requires_Transient_Scope): Avoid returning
299 function results on the secondary stack in so many cases.
301 2015-05-28 Ed Schonberg <schonberg@adacore.com>
303 * sem_util.adb (Wrong_Type): In any instance, do not emit error
304 if type of expression is the partial view of the expected type.
306 2015-05-28 Ed Schonberg <schonberg@adacore.com>
308 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
309 names in named associations only needs to be done within an
310 instance, on a call to a primitive of a formal derived type,
311 where the actual subprogram may have different formal names than
312 those of the primitive operation of the formal type.
313 b) Defaulted parameters must be taken into account when obtaining
314 the names of the formals of the actual subprogram being called.
316 2015-05-28 Robert Dewar <dewar@adacore.com>
318 * sem_ch13.adb, sem_disp.ads: Minor reformatting.
320 2015-05-28 Ed Schonberg <schonberg@adacore.com>
322 * sem_util.adb (Set_Debug_Info_Needed): For a private type
323 whose full view is itself a derived private type, set flag on
324 underlying full view as well, for proper gdb display.
326 2015-05-28 Bob Duff <duff@adacore.com>
328 * exp_tss.ads: Minor comment fix.
329 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
330 Inline init_procs when the type has controlled parts. Remove
331 obsolete comments about those init_procs -- init_procs for
332 such types are no longer complex. A typical init_proc just
333 initializes the 'Tag field, and calls the parent init_proc
334 (e.g. for Limited_Controlled), which calls the grandparent
335 (for Root_Controlled), which does nothing. This all boils down
336 to one instruction when inlined.
337 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
339 2015-05-28 Ed Schonberg <schonberg@adacore.com>
341 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
342 is a derived type and is a generic actual, the selected component
343 appears within an instance body, and the check over the type
344 has failed, examine ancestor types for the desired component.
345 (Find_Component_In_Instance): If record type is a derived type,
346 examine all ancestors in order to locate desired component.
348 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>
350 * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.
352 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
354 * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
355 incomplete type coming from a limited_with and whose non-limited view
356 comes from the main unit.
358 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
360 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
361 code applying atomic checks to the object.
363 2015-05-27 Robert Dewar <dewar@adacore.com>
365 * sem_aux.adb: Minor rewording.
367 2015-05-27 Bob Duff <duff@adacore.com>
369 * exp_prag.adb (Expand_Pragma_Abort_Defer): Make
370 pragma Abort_Defer do nothing if Abort_Allowed is False.
372 2015-05-27 Arnaud Charlet <charlet@adacore.com>

375 sem_elab.ads, g-comlin.ads, errout.ads, exp_ch6.adb, sem_ch4.adb,
376 opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
377 sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.
379 2015-05-27 Doug Rupp <rupp@adacore.com>
381 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
382 well as kernel.
384 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
386 * par_sco.adb (Process_Decision): Store sloc to
387 condition/pragmas SCOs associations into a temporary table before
388 moving them to the SCO_Raw_Hash_Table so that we can back them
389 out just like we do for SCO entries that are simple decisions
390 in an expression context.
392 2015-05-27 Ed Schonberg <schonberg@adacore.com>
394 * sem_ch6.adb (Process_Formals): A non-private formal type that
395 is a limited view does not have a list of private dependents.
397 2015-05-27 Ed Schonberg <schonberg@adacore.com>
399 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
400 the case statement is a compile-time known value, we look for a
401 corresponding alternative to optimize the case statement into a
402 single case. If the type has a static predicate and the expression
403 does not satisfy the predicate, there is no legal alternative and
404 this optimization is not applicable. Excecution is erroneous,
405 or else if assertions are enabled, an exception will be raised
406 earlier, at the point the expression is elaborated.
408 2015-05-27 Robert Dewar <dewar@adacore.com>
410 * sem_elab.adb (Check_Internal_Call_Continue): Suppress
411 warning on Finalize, Adjust, or Initialize if type involved has
412 Warnings_Off set.
414 2015-05-27 Ed Schonberg <schonberg@adacore.com>
416 * sem_aux.adb, sem_aux.ads (First_Discriminant): Return empty when
417 applied to a type with no known discriminants.
419 2015-05-26 Robert Dewar <dewar@adacore.com>
421 * errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.
423 2015-05-26 Bob Duff <duff@adacore.com>
425 * sem_elab.adb (Check_A_Call): In the case where we're
426 calling something in an instance of a generic package that is
427 within this same unit (as the call), make sure we treat it
428 as a call to an entity within the same unit. That is, call
429 Check_Internal_Call, rather than putting "Elaborate_All(X)"
430 on X, which would necessarily result in an elaboration cycle in
431 static-elaboration mode.
433 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
435 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
436 * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
437 parameter into Node parameter and remove Type parameter.
438 Look at Is_Atomic_Or_VFA both on the type and on the object.

440 * exp_aggr.adb (Expand_Record_Aggregate): Likewise.

442 propagating Atomic or VFA from object to locally-defined type.

448 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
450 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Min/Attr_Max>: Do not
451 bother about NaN's if Machine_Overflows is true.
453 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
455 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
456 force evaluation of the expression, if any, when the object has its
457 elaboration delayed. Do not create a variable at global level.
459 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
461 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
462 extra-precision trick to literals. Build SAVE_EXPR manually.
464 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

477 (elaborate_reference): Likewise.
478 (gnat_to_gnu_entity): Call elaborate_reference to elaborate renamings
479 and simplify associated code. Set const_flag to true consistently in
480 conjunction with used_by_ref.
481 * gcc-interface/trans.c (Identifier_to_gnu): Always replace renaming
482 pointers by renamed objects.
483 (outer_atomic_access_required_p): Deal with renamings.
484 (Compilation_Unit_to_gnu): Do not call

561 2015-05-26 Ed Schonberg <schonberg@adacore.com>
563 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
564 of original expression in ASIS mode: does not solve the ASIS

580 2015-05-26 Bob Duff <duff@adacore.com>
582 * treepr.adb: Minor improvement to debugging routines (pp, pn)
583 robustness. Rearrange the code so passing a nonexistent Node_Id
584 prints "No such node" rather than crashing, and causing gdb to
585 generate confusing messages.

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

944 subtype are immediately visible if we are within their scope. This
945 may be needed when a procedure body is both the parent of an

988 parameters that is rewritten as an expression_with_actions,
989 we preserve the original function call node for further use by
990 the caller (typically Expand_Call). In the presence of validity
991 checks, that function call, though it is labelled Analyzed to
992 prevent an infinite recursion, may be rewritten as a temporary
993 by Remove_Side_Effects. Ensure that the caller has access to
994 the original function call to continue expansion.

1107 representation items to determine whether there is a visible
1108 stream operation. The attribute definition clause generated from
1109 the aspect will be inserted at the freeze point of the type,
1110 which may be in the private part and not directly visible,

1386 * exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
1387 Instead of doing literally what the RM calls for, we do something
1388 equivalent that avoids expensive operations inside the loop. If the
1389 container package has appropriate Next, Pseudo_Reference,
1390 Element_Access, Get_Element_Access declarations, we invoke the
1391 optimization.

1505 the presence of a regular with_clause in the enclosing unit,
1506 and will fail if this with_clause is missing. We place the
1507 instance body at the beginning of the enclosing body, which is
1508 the unit being compiled, and ensure that freeze nodes for the
1509 full views of the incomplete types appear before the instance.

2238 proper inheritance of these aspects.

2300 to Freeze_Entity. In addition to the previous processing steps
2301 at the freeze point of an object, this procedure also handles

2320 that predicate functions are constructed.
2322 2015-05-12 Ed Schonberg <schonberg@adacore.com>
2324 * sem_ch6.adb (Process_Formals): If a tagged formal is an
2325 incomplete class-wide type, the subprogram must have a delayed
2326 freeze even though the opertation is not a primitive of the
2327 type. THis ensures that the backend can recover the full view
2328 when elaborating the subprogram declaration.

2355 * sem_ch3.adb (Analyze_Component_Declaration): If the component is
2356 an unconstrained synchronized type with discriminants, create a
2357 constrained default subtype for it, so that the enclosing record
2358 can be given the proper size.
2359 * sem_util.adb (Build_Default_Subtype): If the subtype is created
2360 for a record discriminant, do not analyze the declarztion at
2361 once because it is added to the freezing actions of the enclosing
2362 record type.
2364 2015-05-12 Robert Dewar <dewar@adacore.com>
2366 * exp_prag.adb (Expand_N_Pragma): Rewrite ignored pragma as

3038 expanding a 'Input attribute reference for a class-wide type,
3039 do not generate a separate object declaration for the controlling
3040 tag dummy object; instead, generate the expression inline in the
3041 dispatching call. Otherwise, the declaration (which involves a
3042 call to String'Input, returning a dynamically sized value on the
3043 secondary stack) will be expanded outside of proper secondary
3044 stack mark/release operations, and will thus cause a secondary
3045 stack leak.

4971 ttypes values and the GNAT tree nodes for the standard floating
4972 point types.
4973 * set_targ.adb (Long_Double_Index): The index at which "long
4974 double" gets registered in the FPT_Mode_Table. This is useful to

4985 suitable as a basis to construct the standard Ada floating point
4986 type identified by the input T parameter.
4987 (elaboration code): Register_Back_End_Types unconditionally,
4988 so C_Type_For can operate regardless of -gnateT. Do it
4989 early so we can query it for the floating point sizes, via
4990 FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
4991 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
4992 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
4993 which C type should be used as the basis for the construction
4994 of the Standard Ada floating point types.

5014 has been resolved, and replace the standard renaming declaration
5015 with the declaration of wrapper.
5016 * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
5017 make public for use elsewhere.
5018 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
