2972 2015-10-26 Bob Duff <duff@adacore.com>
2974 * sem_ch3.adb (Derive_Interface_Subprogram): Fix
2975 Is_Abstract_Subprogram, which might have been calculated
2976 incorrectly, because we're passing Ultimate_Alias (Subp) (and
2977 its dispatching type) to Derive_Subprogram, instead of the true
2978 parent subprogram and type.
2980 2015-10-26 Bob Duff <duff@adacore.com>
2982 * sem_ch13.adb (Check_Iterator_Functions): When
2983 printing the "default iterator must be unique" error message,
2984 also print references to the places where the duplicates are
2985 declared. This makes the message clearer.
2987 2015-10-26 Ed Schonberg <schonberg@adacore.com>
2989 * sem_ch12.adb (Analyze_Formal_Package_Declaration): Do not set
2990 Box_Present when the formal part is (others => <>) even though
2991 it is equivalent to a formal part (<>), because ASIS tools depend
2992 on the syntactic setting of this flag.

3017 2015-10-26 Ed Schonberg <schonberg@adacore.com>
3019 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Do not
3020 recheck the consistency betwen the freeze point and the end of
3021 declarations for the expression in an aspect specification,
3022 because it was done already in the analysis of the generic.
3023 Furthermore, the delayed analysis of an aspect of the instance
3024 may produce spurious errors when the generic is a child unit
3025 that references entities in the parent (which might not be in
3026 scope at the freeze point of the instance).
3028 2015-10-26 Yannick Moy <moy@adacore.com>
3030 * sem_res.adb (Resolve_Call): Issue info message
3031 instead of warning when call cannot be inlined in GNATprove mode.
3033 2015-10-26 Arnaud Charlet <charlet@adacore.com>
3035 * exp_ch6.adb (Build_Procedure_Form): Use _result as the

3490 SS_Release for a block statement enclosing the return statement in the

4228 * restrict.ads: minor whitespace cleanup in comment
4230 2015-10-20 Bob Duff <duff@adacore.com>

4251 * a-rbtgso.adb, a-rbtgso.ads: Change all the predefined containers
4252 to share the tampering machinery in Ada.Containers.Helpers. This
4253 reduces the amount of duplicated code, and takes advantage of

4256 Checks" or "if T_Check", so this code can be suppressed with
4257 pragma Suppress or -gnatp.
4258 Add Pseudo_Reference and Get_Element_Access to remaining
4259 containers, so that the compiler can optimize "for ... of" loops.

4264 Makefile.rtl, a-convec.ads: Move helper code from Ada.Containers to a
4265 new package Ada.Containers.Helpers, because otherwise it's not
4266 visible everywhere it needs to be (e.g. in the package
4267 Ada.Containers.Red_Black_Trees, Generic_Tree_Types wants to have
4268 a component of type Tamper_Counts).

4375 * a-coinve.ads, a-coinve.adb: Do the same efficiency
4376 improvements that were already done in the definite case
4377 (Ada.Containers.Vectors, i.e. a-convec). This includes the
4378 ability to suppress checks, the fast path for Append, inlining
4379 as appropriate, and special-casing of "for ... of" loops. Reuse
4380 the tampering machinery that is now in Ada.Containers. Simplify
4381 many operations.
4382 * a-convec.ads, a-convec.adb: Change the code to be more similar
4383 to a-coinve.
4384 * a-finali.ads, a-finali.adb: Expose the "null"-ness of the

4629 the predicate is side-effect free if it does not contain any
4630 variable references.
4632 2015-10-16 Bob Duff <duff@adacore.com>
4634 * a-convec.adb ("="): Previous version depended
4635 on "=" composing, but that doesn't quite work -- we want the "="
4636 operator passed in to the generic. So we need a loop after all.
4638 2015-10-16 Yannick Moy <moy@adacore.com>
4640 * sem_util.adb (Is_Object_Reference): Attribute 'Loop_Entry produces
4641 an object.

4644 2015-10-16 Bob Duff <duff@adacore.com>
4646 * a-contai.ads: Add two check names: Container_Checks and
4647 Tampering_Check. Move the tampering check machinery from
4648 Ada.Containers.Vectors to Ada.Containers. Later we can share it
4649 with other containers.
4650 Disable the tampering machinery in the presence of
4651 Suppress(Tampering_Check).
4652 Simplify the implementation of tampering checks. E.g. use RAII
4653 to make incrementing/decrementing of the counts more concise.
4654 * a-contai.adb: New package body, implementing the above.
4655 * a-convec.ads, a-convec.adb: Use tampering check machinery
4656 in Ada.Containers.
4657 Disable all checking code when checks are suppressed.
4658 Simplify many of the operations. Implement "&" in terms of Append,
4659 rather than "by hand".
4660 Remove: function "=" (L, R : Elements_Array) return Boolean is
4661 abstract; so we can call the predefined "=" on Elements_Array.
4662 For "=" on Vectors: Previously, we returned True immediately if
4663 Left'Address = Right'Address. That seems like a non-optimization
4664 ("if X = X" is unusual), so removed that. Simplify by using
4665 slice comparison ("=" on Element_Array will automatically call
4666 "=" on the components, even if user defined).
4668 2015-10-16 Ed Schonberg <schonberg@adacore.com>
4670 * sem_ch13.adb (Chek_Record_Representation_Clause): When

4714 * sem_ch3.adb (Replace_Anonymous_Access_To_Protected_Subprogram):
4715 When creating a full declaration for a formal parameter, the
4716 entity is labelled as an Itype, so set Associated_Node_For_Itype
4717 accordingly.
4718 * einfo.ads: Clarify use of Associated_Node_For_Itype.
4720 2015-10-16 Bob Duff <duff@adacore.com>

4781 * sem_util.adb (Has_Discrim_Dep_Array): Remove
4782 this function, and the call. No longer needed now that the back

5421 potential addends.
5423 2015-06-01 Pierre-Marie de Rodat <derodat@adacore.com>
5425 * gcc-interface/decl.c (gnat_to_gnu_entity): Replace pointer types with

5445 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
5447 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: If the

5449 it is properly aligned.
5451 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>

5459 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Deal with
5460 address clause on aliased object with unconstrained nominal subtype.
5461 Mark the aligning variable as artificial, do not convert the address

5496 deal with the subtraction of a "negative" value in an unsigned type.
5498 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
5500 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>: Do
5501 not error out on a return type which has a size that overflows if the
5502 return is done by invisible reference.
5504 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
5506 * gcc-interface/utils.c (gnat_pushdecl): Reunify the handling of array

5509 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
5511 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust.
5512 (rewrite_fn): Remove third parameter.
5513 (type_is_padding_self_referential): New inline predicate.
5514 (return_type_with_variable_size_p): Likewise.
5515 * gcc-interface/decl.c (allocatable_size_p): More around.
5516 (cannot_be_superflat_p): Rename into...
5517 (cannot_be_superflat ): ...this.
5518 (initial_value_needs_conversion): New predicate.
5519 (gnat_to_gnu_entity): Invoke type_is_padding_self_referential,
5520 initial_value_needs_conversion and adjust to above renaming.
5521 For a renaming, force the materialization if the inner expression
5522 is compound. Adjust calls to elaborate_reference and build a
5523 compound expression if needed.
5524 (struct er_dat): Add N field.
5525 (elaborate_reference_1): Remove N parameter and adjust.
5526 (elaborate_reference): Add INIT parameter and pass it in the call to
5527 gnat_rewrite_reference. Adjust initial expression.
5528 * gcc-interface/trans.c (Call_to_gnu): Treat renamings the same way as
5529 regular object declarations when it comes to creating a temporary.
5530 Adjust call to gnat_stabilize_reference and build a compound expression
5531 if needed. Invoke return_type_with_variable_size_p.
5532 (gnat_to_gnu): Invoke type_is_padding_self_referential. In case #4,
5533 return a call to a function unmodified if it returns with variable size
5534 and is also the initial expression in an object declaration.
5535 * gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: Use the RHS'
5536 type if it is a call to a function that returns with variable size.
5537 (build_unary_op): Invoke type_is_padding_self_referential.
5538 (gnat_stabilize_reference_1): Remove N parameter and adjust.
5539 (gnat_stabilize_reference): Add INIT parameter and pass it in the call
5540 to gnat_rewrite_reference.

5542 <COMPOUND_EXPR>: New case.
5544 2015-05-28 Ed Schonberg <schonberg@adacore.com>
5546 * sem_ch3.adb (Is_Visible_Component): Component is visible
5547 in a derived type if inherited through an ancestor that has a
5548 partial view of the original type holding the component, if the
5549 full view of that original type is in scope.
5550 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
5552 2015-05-28 Bob Duff <duff@adacore.com>
5554 * sem_util.adb (Requires_Transient_Scope): For definite untagged
5555 subtypes, we should never have to use the secondary stack. This moves
5556 toward that goal. But there are still cases that don't work.
5557 Here, we move the check for Is_Definite first, but add a
5558 special-purpose check for Has_Discrim_Dep_Array.
5560 2015-05-28 Bob Duff <duff@adacore.com>
5562 * sem_util.adb (Requires_Transient_Scope): Avoid returning
5563 function results on the secondary stack in so many cases.
5565 2015-05-28 Ed Schonberg <schonberg@adacore.com>
5567 * sem_util.adb (Wrong_Type): In any instance, do not emit error
5568 if type of expression is the partial view of the expected type.
5570 2015-05-28 Ed Schonberg <schonberg@adacore.com>
5572 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
5573 names in named associations only needs to be done within an
5574 instance, on a call to a primitive of a formal derived type,
5575 where the actual subprogram may have different formal names than
5576 those of the primitive operation of the formal type.
5577 b) Defaulted parameters must be taken into account when obtaining
5578 the names of the formals of the actual subprogram being called.
5580 2015-05-28 Robert Dewar <dewar@adacore.com>
5582 * sem_ch13.adb, sem_disp.ads: Minor reformatting.
5584 2015-05-28 Ed Schonberg <schonberg@adacore.com>
5586 * sem_util.adb (Set_Debug_Info_Needed): For a private type
5587 whose full view is itself a derived private type, set flag on
5588 underlying full view as well, for proper gdb display.
5590 2015-05-28 Bob Duff <duff@adacore.com>
5592 * exp_tss.ads: Minor comment fix.
5593 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
5594 Inline init_procs when the type has controlled parts. Remove
5595 obsolete comments about those init_procs -- init_procs for
5596 such types are no longer complex. A typical init_proc just
5597 initializes the 'Tag field, and calls the parent init_proc
5598 (e.g. for Limited_Controlled), which calls the grandparent
5599 (for Root_Controlled), which does nothing. This all boils down
5600 to one instruction when inlined.
5601 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
5603 2015-05-28 Ed Schonberg <schonberg@adacore.com>
5605 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
5606 is a derived type and is a generic actual, the selected component
5607 appears within an instance body, and the check over the type
5608 has failed, examine ancestor types for the desired component.
5609 (Find_Component_In_Instance): If record type is a derived type,
5610 examine all ancestors in order to locate desired component.
5612 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>
5614 * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.
5616 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
5618 * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
5619 incomplete type coming from a limited_with and whose non-limited view
5620 comes from the main unit.
5622 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
5624 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
5625 code applying atomic checks to the object.
5627 2015-05-27 Robert Dewar <dewar@adacore.com>
5629 * sem_aux.adb: Minor rewording.
5631 2015-05-27 Bob Duff <duff@adacore.com>
5633 * exp_prag.adb (Expand_Pragma_Abort_Defer): Make
5634 pragma Abort_Defer do nothing if Abort_Allowed is False.
5636 2015-05-27 Arnaud Charlet <charlet@adacore.com>
5638 * exp_ch9.adb, sem_util.adb, sem_util.ads, s-stposu.adb, s-spsufi.ads,
5639 sem_elab.ads, g-comlin.ads, errout.ads, exp_ch6.adb, sem_ch4.adb,
5640 opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
5641 sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.
5643 2015-05-27 Doug Rupp <rupp@adacore.com>
5645 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
5646 well as kernel.
5648 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
5650 * par_sco.adb (Process_Decision): Store sloc to
5651 condition/pragmas SCOs associations into a temporary table before
5652 moving them to the SCO_Raw_Hash_Table so that we can back them
5653 out just like we do for SCO entries that are simple decisions
5654 in an expression context.
5656 2015-05-27 Ed Schonberg <schonberg@adacore.com>
5658 * sem_ch6.adb (Process_Formals): A non-private formal type that
5659 is a limited view does not have a list of private dependents.
5661 2015-05-27 Ed Schonberg <schonberg@adacore.com>
5663 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
5664 the case statement is a compile-time known value, we look for a
5665 corresponding alternative to optimize the case statement into a
5666 single case. If the type has a static predicate and the expression
5667 does not satisfy the predicate, there is no legal alternative and
5668 this optimization is not applicable. Excecution is erroneous,
5669 or else if assertions are enabled, an exception will be raised
5670 earlier, at the point the expression is elaborated.
5672 2015-05-27 Robert Dewar <dewar@adacore.com>
5674 * sem_elab.adb (Check_Internal_Call_Continue): Suppress
5675 warning on Finalize, Adjust, or Initialize if type involved has
5676 Warnings_Off set.
5678 2015-05-27 Ed Schonberg <schonberg@adacore.com>
5680 * sem_aux.adb, sem_aux.ads (First_Discriminant): Return empty when
5681 applied to a type with no known discriminants.
5683 2015-05-26 Robert Dewar <dewar@adacore.com>
5685 * errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.
5687 2015-05-26 Bob Duff <duff@adacore.com>
5689 * sem_elab.adb (Check_A_Call): In the case where we're
5690 calling something in an instance of a generic package that is
5691 within this same unit (as the call), make sure we treat it
5692 as a call to an entity within the same unit. That is, call
5693 Check_Internal_Call, rather than putting "Elaborate_All(X)"
5694 on X, which would necessarily result in an elaboration cycle in
5695 static-elaboration mode.
5697 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
5699 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
5700 * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
5701 parameter into Node parameter and remove Type parameter.

5704 * exp_aggr.adb (Expand_Record_Aggregate): Likewise.
5705 (Process_Atomic_Independent_Shared_Volatile): Remove code
5706 propagating Atomic or VFA from object to locally-defined type.
5708 2015-05-26 Bob Duff <duff@adacore.com>
5710 * exp_ch7.adb: Minor comment fix.
5712 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
5714 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Min/Attr_Max>: Do not
5715 bother about NaN's if Machine_Overflows is true.
5717 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
5719 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
5720 force evaluation of the expression, if any, when the object has its
5721 elaboration delayed. Do not create a variable at global level.
5723 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
5725 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
5726 extra-precision trick to literals. Build SAVE_EXPR manually.
5728 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

5741 (elaborate_reference): Likewise.
5742 (gnat_to_gnu_entity): Call elaborate_reference to elaborate renamings
5743 and simplify associated code. Set const_flag to true consistently in
5744 conjunction with used_by_ref.
5745 * gcc-interface/trans.c (Identifier_to_gnu): Always replace renaming
5746 pointers by renamed objects.
5747 (outer_atomic_access_required_p): Deal with renamings.

5749 invalidate_global_nonconstant_renamings.

5844 2015-05-26 Bob Duff <duff@adacore.com>
5846 * treepr.adb: Minor improvement to debugging routines (pp, pn)
5847 robustness. Rearrange the code so passing a nonexistent Node_Id

6208 subtype are immediately visible if we are within their scope. This
6209 may be needed when a procedure body is both the parent of an
6210 instantiated child unit, and is itself used to inline a local

6252 parameters that is rewritten as an expression_with_actions,
6253 we preserve the original function call node for further use by
6254 the caller (typically Expand_Call). In the presence of validity
6255 checks, that function call, though it is labelled Analyzed to
6256 prevent an infinite recursion, may be rewritten as a temporary
6257 by Remove_Side_Effects. Ensure that the caller has access to
6258 the original function call to continue expansion.

6370 has aspect specifications, examine the corresponding list of
6371 representation items to determine whether there is a visible
6372 stream operation. The attribute definition clause generated from
6373 the aspect will be inserted at the freeze point of the type,
6374 which may be in the private part and not directly visible,
6375 but the aspect makes the operation available to a client.

6591 between the two operations when they are operations of a formal
6592 derived type.
6594 2015-05-22 Bob Duff <duff@adacore.com>
6596 * a-convec.ads, a-convec.adb (Append): Check for fast path. Split

6648 declarations added for use by performance improvements in exp_ch5.adb.
6649 * snames.ads-tmpl: New names referenced by exp_ch5.adb.
6650 * exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
6651 Instead of doing literally what the RM calls for, we do something
6652 equivalent that avoids expensive operations inside the loop. If the
6653 container package has appropriate Next, Pseudo_Reference,
6654 Element_Access, Get_Element_Access declarations, we invoke the
6655 optimization.
6656 * snames.ads-tmpl: Note speed improvement.
6658 2015-05-22 Eric Botcazou <ebotcazou@adacore.com>

6767 the declaration because full views have not been seen yet. Any
6768 use of the non-limited views in the instance body requires
6769 the presence of a regular with_clause in the enclosing unit,
6770 and will fail if this with_clause is missing. We place the
6771 instance body at the beginning of the enclosing body, which is
6772 the unit being compiled, and ensure that freeze nodes for the
6773 full views of the incomplete types appear before the instance.

8306 call to String'Input, returning a dynamically sized value on the
8307 secondary stack) will be expanded outside of proper secondary

10234 ttypes values and the GNAT tree nodes for the standard floating
10235 point types.
10236 * set_targ.adb (Long_Double_Index): The index at which "long
10237 double" gets registered in the FPT_Mode_Table. This is useful to
10238 know whether we have a "long double" available at all and get at

10248 suitable as a basis to construct the standard Ada floating point
10249 type identified by the input T parameter.
10250 (elaboration code): Register_Back_End_Types unconditionally,
10251 so C_Type_For can operate regardless of -gnateT. Do it
10252 early so we can query it for the floating point sizes, via
10253 FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
10254 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
10255 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
10256 which C type should be used as the basis for the construction
10257 of the Standard Ada floating point types.

10280 make public for use elsewhere.
10281 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):

10283 constructed.
