[Ada] Fix leak of Do_Range_Check flag in -gnatVa mode
This fixes a small glitch in Insert_Valid_Check, which needs to
propagate the Do_Range_Check flag onto the rewritten expression, but
uses its Original_Node as the source of the copy. Now Original_Node
does not necessarily point to the node that was just rewritten, but to
the ultimately original node, which is not the same node if the
expression was rewritten multiple times. The end result is that a
stalled Do_Range_Check flag can be wrongly resintated and leak to the
code generator.

[arm] Recognize thumb2 16-bit variants of the add and compare instructions
The addsi3_compare_op[12] patterns currently only have constraints to
pick the 32-bit variants of the instructions. Although the assembler
may sometimes opportunistically match a 16-bit t2 instruction, there's
no real control over that within the compiler. Consequently we might
emit a 32-bit adds instruction with a 16-bit subs instruction would
serve equally well. We do, of course still have to be careful about
the small number of boundary cases by controlling the order quite
carefully.
This patch adds the constraints and templates to match the t2 16-bit
variants of these instructions. Now, for example, we can generate
subs r0, r0, #1 // 16-bit instruction

skip Cholesky decomposition in is>>n_mv_dist
normal_mv_distribution maintains the variance-covariance matrix param
in Cholesky-decomposed form. Existing param_type constructors, when
taking a full or lower-triangle varcov matrix, perform Cholesky
decomposition to convert it to the internal representation. This
internal representation is visible both in the varcov() result, and in
the streamed-out representation of a normal_mv_distribution object.
The problem is that when that representation is streamed back in, the
read-back decomposed varcov matrix is used as a lower-triangle
non-decomposed varcov matrix, and it undergoes Cholesky decomposition
again. So, each cycle of stream-out/stream-in changes the varcov
matrix to its "square root", instead of restoring the original
params.
This patch includes Corentin's changes that introduce verification in
testsuite/ext/random/normal_mv_distribution/operators/serialize.cc and
other similar tests that the object read back in compares equal to the

[C] Fix bogus nested enum error message
For:
enum a { A };
enum a { B };
we emit a bogus error about nested definitions before the real error:
foo.c:2:6: error: nested redefinition of ‘enum a’
2 | enum a { B };
| ^
foo.c:2:6: error: redeclaration of ‘enum a’
foo.c:1:6: note: originally defined here
1 | enum a { A };
| ^
This is because we weren't clearing C_TYPE_BEING_DEFINED once the
definition was over.
I think it's OK to clear C_TYPE_BEING_DEFINED even for a definition
that actually is nested (and so whose outer definition is still open),
since we'll already have given an error by then. It means that second
and subsequent attempts to define a nested enum will usually get the
redeclaration error instead of the nested error, but that seems just
as accurate (nested_first and nested_second in the test). The only
exception is if the first nested enum was also invalid by being empty,
but then the enum as a whole has already produced two errors
(nested_empty in the test).

This patch merges the SVE FP rounding patterns with the other SVE
FP unary patterns.
At the moment, we only generate unary FP operations for full vectors,
so we can use (sqrt:VNx4SF ...) etc. in the rtl pattern. With the ACLE,
it's also possible to generate predicated operations on partial vectors
without specifying a value for inactive lanes. (sqrt:VNx4SF ...) would
then have different faulting behaviour from the instruction that the

[AArch64] Reorganise aarch64-sve.md
aarch64-sve.md was getting a bit jumbled, with related operations
separated by unrelated operations. Also, many SVE instructions need
to have several patterns due to the various ways in which predication
can be used, and it was getting hard to tell which instructions had a
complete set of patterns.
This patch therefore tries to use an explicit grouping scheme.
Banner comments are usually frowned on, but md files have been
a traditional exception (e.g. when using Mike's template for
new targets).
The patch also lists the instructions implemented by each section,
so that it's possible to search the file by instruction mnemonic.
I wouldn't be surprised if I end up having to rip out the contents
section, but I found it useful for the month or so that that I've
been using it locally. The patch checks that the contents remain
up-to-date by running a checking script during an early stage of
the build.
No functional change intended.

PR driver/91130 Use CL_DRIVER when handling of COLLECT_GCC_OPTIONS in lto-wrapper.c
Some options are handled differently by the main driver (gcc, g++,
etc) from the back-end compiler programs (cc1, cc1plus, etc) in that
in the driver they do not take an additional argument, while in the
compiler programs they do. The processing option option CL_DRIVER
controls this alternative interpretation of the options.
The environment variable COLLECT_GCC_OPTIONS is the list of options to
add to a compile if the compiler re-invokes itself at some point. As
such, the options are driver options, so CL_DRIVER should be used when
processing this list. Currently lto-wrapper is doing this

Here, since the call to g is not type-dependent, we call mark_used on it to
determine its return type. This also wants to instantiate the
noexcept-expression. But since nothing in maybe_instantiate_noexcept was
calling push_to_top_level, we substituted b.i with processing_template_decl
set, so we left it unresolved for later access checking. As a result, the
type of C::g<int> remained instantiation-dependent, leading to an ICE in

(gimplify_omp_for): Don't do C++ random access iterator clause
adjustments on combined constructs from OMP_LOOP. For OMP_LOOP,
don't predetermine the artificial iterator in case of C++ random
access iterators as lastprivate, but private. For OMP_LOOP, force
bind expr around simd body and force for_pre_body before the
construct. Use OMP_CLAUSE_LASTPRIVATE_LOOP_IV instead of
OMP_CLAUSE_LASTPRIVATE_TASKLOOP_IV.
(gimplify_omp_loop): Add firstprivate clauses on OMP_PARALLEL for
diff var of C++ random access iterators. Handle
OMP_CLAUSE_FIRSTPRIVATE. For OMP_CLAUSE_LASTPRIVATE_LOOP_IV, if
not outermost also add OMP_CLAUSE_FIRSTPRIVATE, and in both cases

RISC-V: Handle extensions combination correctly in multilib-generator.
Input string consist of four parts:
<primary arch>-<abi>-<additional arches>-<extensions>
and generator doing combination with <extensions> part, but it just
append the extension at the end of arch string, it might generate
invalid arch.
For example, without this patch `./multilib-generator rv32imafc-ilp32--d`
will generate:
MULTILIB_OPTIONS = march=rv32imafc/march=rv32imafcd mabi=ilp32
^^^^^^^^^^
and rv32imafcd is not in canonical order.
Tested with python 2.7 and python 3.6/3.7.

PR c++/88095, CTAD for literal operator templates per P0732
This patch fixes PR c++/88095: class nontype template parameter UDL string
literals doesn't accepts deduction placeholder
It also addresses a latent issue; literal operator templates with template
parameter packs of literal class type were previously accepted. The patch
corrects this and adds a test (udlit-class-nttp-neg.C).
This fix is needed for one of the char8_t remediation approaches documented
in P1423, and may be helpful for existing code bases impacted by the char8_t
changes adopted via P0482 for C++20.
