missing optional args.
2021-09-21 Yannick Moy <moy@adacore.com>
* gen_il-gen.adb (Put_Opt_Subtype): Add suffix.
2021-09-21 Justin Squirek <squirek@adacore.com>

2021-09-21 Eric Botcazou <ebotcazou@adacore.com>
* gnat_ugn.texi: Regenerate.
2021-09-21 Matthieu Eyraud <eyraud@adacore.com>
* par_sco.adb (Traverse_One): Add support for pragma Invariant /
Type_Invariant.
2021-09-21 Bob Duff <duff@adacore.com>
* gen_il-gen.adb (Put_Opt_Subtype): Print out subtypes of the
form:
subtype Opt_N_Declaration is
Node_Id with Predicate =>
Opt_N_Declaration = Empty or else
Opt_N_Declaration in N_Declaration_Id;
One for each node or entity type, with the predicate allowing
Empty.
* atree.adb (Parent, Set_Parent): Remove unnecessary "Atree.".
2021-09-21 Patrick Bernardi <bernardi@adacore.com>
* bindgen.adb (Gen_Adainit): For targets that suppress the
standard library: set the default stack size global variable if
a value is provided via the -d switch, and generate a call to
__gnat_initialize_stack_limit if stack checking using stack
limits is enabled.
2021-09-21 Bob Duff <duff@adacore.com>
* sem_ch13.adb (Stream_Size): Print message about allowed stream
sizes even if other error were already found. This avoids
falling into the 'else', which prints "Stream_Size cannot be
given for...", which is misleading -- the Size COULD be given if
it were correct.
2021-09-21 Daniel Mercier <mercier@adacore.com>
* exp_util.adb (Build_Temporary): In case of an external DISCR
symbol, set the related expression for CodePeer so that a more
comprehensible message can be emitted to the user.
2021-09-21 Eric Botcazou <ebotcazou@adacore.com>
* libgnat/s-dwalin.adb (Parse_Header): Tweak comments.
(Read_Entry_Format_Array): Tweak exception message.

2021-09-21 Bob Duff <duff@adacore.com>
* uintp.ads, uintp.adb (UI_Is_In_Int_Range): Change the type of
the formal parameter to Valid_Uint. Remove code that preserved
the previous behavior, and replace it with an assertion. The
previous behavior is no longer needed given the recent change to
gigi.
(No, Present): Add comment.
2021-09-21 Bob Duff <duff@adacore.com>
* sem_eval.adb (Fold_Shift): Replace an if_expression with an
if_statement.
2021-09-21 Bob Duff <duff@adacore.com>
* uintp.ads, uintp.adb: Add assertions.
(Ubool, Opt_Ubool): New "boolean" subtypes.
(UI_Is_In_Int_Range): The parameter should probably be
Valid_Uint, but we don't change that for now, because it causes
failures in gigi.
* sem_util.ads, sem_util.adb (Is_True, Is_False,
Static_Boolean): Use Opt_Ubool subtype. Document the fact that
Is_True (No_Uint) = True. Implement Is_False in terms of
Is_True. We considered changing Static_Boolean to return Uint_1
in case of error, but that doesn't fit in well with
Static_Integer.
(Has_Compatible_Alignment_Internal): Deal with cases where Offs
is No_Uint. Change one "and" to "and then" to ensure we don't
pass No_Uint to ">", which would violate the new assertions.
* exp_util.adb, freeze.adb, sem_ch13.adb: Avoid violating new
assertions in Uintp.
2021-09-21 Eric Botcazou <ebotcazou@adacore.com>
* libgnat/s-dwalin.adb (To_File_Name): Fetch only the last string
from the .debug_line_str section.
(Symbolic_Address.Set_Result): Likewise.
2021-09-21 Eric Botcazou <ebotcazou@adacore.com>
* libgnat/s-dwalin.adb (Skip_Form): Fix cases of DW_FORM_addrx
and DW_FORM_implicit_const. Replace Constraint_Error with
Dwarf_Error.
2021-09-21 Ghjuvan Lacambre <lacambre@adacore.com>
* exp_pakd.adb (Expand_Packed_Not): Replace expression with
statement.
2021-09-21 Ghjuvan Lacambre <lacambre@adacore.com>
* sem_eval.adb (Is_Static_Subtype): Take predicates created
through "predicate" pragma into account.
2021-09-21 Frederic Konrad <konrad@adacore.com>
* Makefile.rtl (aarch64-rtems*): Add GNATRTL_128BIT_PAIRS to
the LIBGNAT_TARGET_PAIRS list and also GNATRTL_128BIT_OBJS to
the EXTRA_GNATRTL_NONTASKING_OBJS list.
2021-09-21 Gary Dismukes <dismukes@adacore.com>
* sem_ch4.adb (Remove_Abstract_Operations): Add condition to
test for an E_Operator as part of criteria for setting
Abstract_Op on interpretations involving predefined operators.
2021-09-21 Javier Miranda <miranda@adacore.com>
* exp_ch6.adb (Expand_Simple_Function_Return): For explicit
dereference of type conversion, enable code that ensures that
the tag of the result is that of the result type.
2021-09-21 Bob Duff <duff@adacore.com>
* einfo-utils.adb: Add support (currently disabled) for using
"initial zero" instead of "Uint_0" to represent "unknown". Call
Known_ functions, instead of evilly duplicating their code
inline.
* fe.h (No_Uint_To_0): New function to convert No_Uint to
Uint_0, in order to preserve existing behavior.
(Copy_Esize, Copy_RM_Size): New imports from Einfo.Utils.
* cstand.adb: Set size fields of Standard_Debug_Renaming_Type
and Standard_Exception_Type.
* checks.adb, exp_attr.adb, exp_ch3.adb, exp_ch5.adb,
exp_ch6.adb, exp_pakd.adb, exp_util.adb, freeze.adb, itypes.adb,
layout.adb, repinfo.adb, sem_attr.adb, sem_ch12.adb,
sem_ch13.adb, sem_ch13.ads, sem_ch3.adb, sem_ch7.adb,
sem_util.adb: Protect calls with Known_..., use Copy_... Remove
assumption that Uint_0 represents "unknown".
* types.ads (Nonzero_Int): New subtype.
* gcc-interface/decl.c, gcc-interface/trans.c: Protect calls
with Known_... and use Copy_... as appropriate, to avoid
blowing up in unknown cases. Similarly, call No_Uint_To_0 to
preserve existing behavior.
2021-09-21 Steve Baird <baird@adacore.com>
* sem_ch13.adb (Analyze_Aspect_Specifications): Add a new nested
function, Directly_Specified, and then use it in the
implementation of the required check.
2021-09-21 Steve Baird <baird@adacore.com>
* libgnat/a-costso.ads, libgnat/a-costso.adb: A new library
unit, Ada.Containers.Stable_Sorting, which exports a pair of
generics (one within the other) which are instantiated by each
of the 5 doubly-linked list container generics to implement
their respective Sort procedures. We use a pair of generics,
rather than a single generic, in order to further reduce code
duplication. The outer generic takes a formal private Node_Ref
type representing a reference to a linked list element. For some
instances, the corresponding actual parameter will be an access
type; for others, it will be the index type for an array.
* Makefile.rtl: Include new Ada.Containers.Stable_Sorting unit.
* libgnat/a-cbdlli.adb, libgnat/a-cdlili.adb,
libgnat/a-cfdlli.adb, libgnat/a-cidlli.adb, libgnat/a-crdlli.adb
(Sort): Replace existing Sort implementation with a call to an
instance of
Ada.Containers.Stable_Sorting.Doubly_Linked_List_Sort. Declare
the (trivial) actual parameters needed to declare that instance.
* libgnat/a-cfdlli.ads: Fix a bug encountered during testing in
the postcondition for M_Elements_Sorted. With a partial
ordering, it is possible for all three of (X < Y), (Y < X),
and (X = Y) to be simultaneously false, so that case needs to
handled correctly.
2021-09-21 Piotr Trojanek <trojanek@adacore.com>
* errout.adb (Error_Msg_Internal): Fix references to Sptr and
Optr in comment; fix grammar of "low-level" where it is used as
an adjective.
2021-09-21 Piotr Trojanek <trojanek@adacore.com>
* errout.adb (Write_Source_Code_Lines): Use Cur_Loc before
incrementing it, so that we don't need to decrement it.
2021-09-21 Yannick Moy <moy@adacore.com>
* errout.adb (Get_Line_End): Do not allow the result to go past
the end of the buffer.
2021-09-21 Ed Schonberg <schonberg@adacore.com>
* sem_ch3.adb (Process_Discriminant_Expressions): If the
constraint is for a Component_Definition that appears in a
Component_Declaration, the entity to be used to create the
potentially global symbol is the Defining_Identifier of the
Component_Declaration.
2021-09-21 Bob Duff <duff@adacore.com>
* libgnat/a-stbufi.ads, libgnat/a-stbufi.adb: Change all
occurrences of GNAT.OS_Lib to System.OS_Lib.
2021-09-20 Piotr Trojanek <trojanek@adacore.com>
* inline.adb (Has_Excluded_Declaration): Remove redundant guard;
