2022-05-19 Eric Botcazou <ebotcazou@adacore.com>
* gcc-interface/decl.cc (gnat_to_gnu_entity) <E_Record_Subtype>: If
it is a special subtype designated by an access subtype, then defer

2022-05-19 Eric Botcazou <ebotcazou@adacore.com>
* gcc-interface/ada-tree.h, gcc-interface/ada.h,

* sem_ch13.adb (Build_Predicate_Functions): If a semantic error

specifications in the same way as is done for CodePeer and
SPARK. This avoids an internal compiler error if
Ancestor_Predicate_Function_Called is True but Result_Expr is
not an N_And_Then node (and is therefore unsuitable as an
argument in a call to Left_Opnd).

not plural; we no longer build a Predicate_M function. Delete
Predicate_M references. Add new Boolean parameter for predicate
functions when needed. Restructure body of generated predicate
functions to implement required Predicate_Failure behavior and
to set new Predicate_Expression attribute. Remove special
treatment of raise expressions within predicate expressions.

Predicate_Function_Needs_Membership_Parameter): New functions.
* sem_util.adb (Is_Current_Instance): Fix bugs which caused
wrong result.
(Is_Current_Instance_Reference_In_Type_Aspect): Delete
Is_Predicate_Function_M reference.
(Predicate_Failure_Expression): New function.

references.
2022-05-19 Eric Botcazou <ebotcazou@adacore.com>
* exp_ch6.adb (Expand_Call_Helper): Adjust comment.

from the constructed IF statement.
2022-05-19 Piotr Trojanek <trojanek@adacore.com>
* exp_ch9.adb (Build_Find_Body_Index): Remove IF statement whose
condition was true-by-construction; remove excessive assertion
(since the call to Elsif_Parts will check that Nod is present
and it is an if-statement).
2022-05-19 Arnaud Charlet <charlet@adacore.com>
* gnat1drv.adb, gnatcmd.adb: Remove references to gnatfind/xref.

* erroutc.ads: Fix a single-character typo in a comment.
* exp_aggr.adb: Fix a single-character typo in a comment.
Replace several pairs of calls to Low_Bound and
High_Bound (which do not handle an identifier that denotes a
scalar subtype) with corresponding calls to Get_Index_Bounds

Component_Associations attribute of a null array aggregate to
New_List.
* sem_aggr.ads: New visible function
Is_Null_Array_Aggregate_High_Bound.
* sem_aggr.adb (Is_Null_Array_Aggregate_High_Bound,
Is_Null_Aggregate, Resolve_Null_Array_Aggregate): New functions.
(Resolve_Aggregate): Recognize null array aggregates (using
Is_Null_Aggregate) and, when one is recognized, resolve
it (using Resolve_Null_Array_Aggregate). Avoid calling
Array_Aggr_Subtype for a null array aggregate; the needed
subtype is built in Resolve_Null_Array_Aggregate. Do not
incorrectly flag a null aggregate (after it is transformed by
expansion) as being both positional and named.
* sem_attr.adb (Eval_Attribute): Special treatment for null
array aggregate high bounds to avoid incorrectly flagging
something like Integer'Pred (Integer'First) as an illegal static
expression.
* sem_eval.adb (Out_Of_Range): Special treatment for null array
aggregate high bounds to avoid incorrectly flagging something
like Integer'Pred (Integer'First) as an illegal static
expression.

Lemma_Shift_Left, Lemma_Shift_Right): Define or complete lemmas.
(Scaled_Divide): Add ghost code.
2022-05-19 Bob Duff <duff@adacore.com>
* exp_pakd.adb (Expand_Packed_Eq): Replace the check for *same*
modular type, with a check for any modular type, and assert that
the two types have the same modulus and so on.
* exp_pakd.ads: Minor comment improvements.
2022-05-19 Bob Duff <duff@adacore.com>
* style.adb (Check_Identifier): Deal with the case where a
record component definition has been transformed; we want to
warn if the original came from source.
* libgnat/s-objrea.ads, libgnat/s-objrea.adb: Fix casing of MF
to be consistent.
* uname.adb: Fix casing of Chars to be consistent.
* sem_util.ads: Minor comment fix.

use CW_Or_Needs_Finalization for those returned on the secondary.
* exp_util.adb (Build_Allocate_Deallocate_Proc): Return early
for the return stack pool.
(Remove_Side_Effects): Call CW_Or_Needs_Finalization.
* fe.h (Requires_Transient_Scope): Delete.

to False when generating C code or if -gnatd_r is specified.

* rtsfind.ads (RTU_Id): Add System_Return_Stack.
(RE_Id): Add RE_RS_Allocate and RE_RS_Pool.

(CW_Or_Needs_Finalization): Declare.
(Requires_Transient_Scope): Adjust description.
(Returns_On_Secondary_Stack): Declare.
* sem_util.adb (Compute_Returns_By_Ref): Set Returns_By_Ref on types
which need finalization if they are returned on the secondary stack.
(CW_Or_Has_Controlled_Part): Rename to...
(CW_Or_Needs_Finalization): ...this.
(Requires_Transient_Scope): Move bulk of implementation to...
(Returns_On_Secondary_Stack): ...here. Return true for types which
need finalization only if the back-end return slot is not supported.
* libgnat/s-retsta.ads: New file.

In the return by invisible reference, skip the copy if the source
is the same as the destination.

the return stack pool.

and do not override them at -Os.
