* contracts.adb (Add_Invariant_And_Predicate_Checks): Relax the

procedure's nested postconditions procedure.

This fixes the sorting of to copy symbols in lto_output introduced
with GCC 10 to not depend on the actual values of the randomness
we append to LTO section names but instead on the order they appear
in the unsorted array.
This fixed observed debug info differences due to tree merging
prevailing different early debug pointers.

* lto-streamer-out.c (cmp_symbol_files): Use the computed

This makes the formatting in <optional> consistent and also removes
redundant && tokens from template arguments for traits like
is_constructible and is_convertible.

* include/std/optional (_Optional_payload_base, _Optional_base)
(optional, __optional_hash_call_base): Adjust whitespace and
other formatting. Remove redundant && tokens on template

The standard rquires that std::make_optional is constrained similarly to
the std::optional constructors, which our implementation fails to do.
As a conforming extension this also adds a noexcept-specifier to each
std::make_optional overload.

The ABI exception helpers like __throw were being created by first
looking for them, and then adding if not found. Primarily because
libitm wasn't declaring them with the correct exception specifiers. I
fixed libitm a while back, so let's just use push_library_fn and let
the symbol table machinery deal with duplicates. push_library_fn was
making the assumtion there wasn't already a decl available, by always
returning the new decl. Bad things would happen if there was a
duplicate, because duplicate_decls explicitly gcc_frees the new decl.
Fixed by having it return whatever pushdecl returns.

This fixes bogus misalignment calculation for negative steps
since an assertion a previous comment indicated no longer holds:
/* DR_STEP(dr) is the same as -TYPE_SIZE of the scalar type,
otherwise we wouldn't be here. */
Thus the following replaces DR_STEP by -TYPE_SIZE.

* libgnat/g-catiio.ads: Document newly supported format. Add
ISO_Time constant, for convenience.
* libgnat/g-catiio.adb (Image_Helper): New helper function to do
all the formatting work, called by the two exported Image
functions. Add support for "%:::z" here. Add a Time_Zone
parameter used by the "%:::z" processing. This parameter is not
used for the actual time zone computations; local time is always
used for that, for ease of implementation reasons. It would
make sense to use Append throughout this function, but that's a
cleanup for another day.
(Image): Modify these to pass the local time zone, or the
specified time zone, as appropriate.

optional time zone, rather than making these alternatives to
each other.

* libgnat/g-catiio.adb (Parse_ISO_8601): Minor cleanups:
Give some objects clearer names.
Make some objects more local to where they are used.
Remove some validity checks that can't fail, because some of
the variables tested have been moved so they're not visible here.
Anyway, Wrong_Syntax is about errors in the input, not data
validity.
Use Time_Zone_Seen instead of Local_Sign = ' ' to determine
that a time zone indication was seen.
We don't need to distinguish two different kinds of
syntax error (End_Of_Source_Reached and Wrong_Syntax),
so use Wrong_Syntax always.
Remove comment, "Certain scanning scenarios may handle
this exception on their own."; there are no such scenarios.

* libgnat/g-catiio.ads, libgnat/g-catiio.adb (Image): New

* libgnat/g-catiio.adb (Parse_ISO_8601): New name for
Parse_ISO_8861_UTC. 8601 is the correct ISO standard number.
Also, "UTC" was confusing. All Time values are represented in
UTC, but the ISO 8601 date strings include a time zone.
If a time zone was specified, call
Ada.Calendar.Formatting.Time_Of instead of
GNAT.Calendar.Time_Of, because the latter adjusts to the current
time zone, whereas we want to use (just) the time zone specified
in the ISO string. This allows us to pass Time_Zone instead to
Time_Of, instead of adjusting by Local_Disp by hand.
If no time zone was specified, call GNAT.Calendar.Time_Of as
before.
Use expanded names to clarify which Time_Of is being called.
Remove redundant comment, and move nonredundant part of the
commment to the spec.
