Unshare DR_STEP before gimplifying it
In this testcase we use an unmasked SVE loop with an Advanced SIMD
epilogue (because we don't yet support fully-masked downward loops).
The main loop uses a gather load for the strided access while the
epilogue loop builds the access from scalars instead. In both cases
we gimplify expressions based on the DR_STEP and insert them in the
loop preheader.
The problem was that the gather load code didn't copy the DR_STEP before
gimplifying it, meaning that the epilogue loop tried to reuse a result
from the (non-dominating) main loop preheader.
It looks at first glance like there could be other instances of this too,
but this patch just deals with the gather/scatter case.

Define HAVE_ for math long double functions declared in vxworks headers
When cross-building for vxworks, test for declarations of long double

cross compiling, because link tests don't work, or ever really, but
not defining them as available causes replacements to be defined in

[C++] Make same_type_p return false for gnu_vector_type_p differences (PR 92789)
As Jason pointed out in the review of the C++ gnu_vector_type_p patch:
https://gcc.gnu.org/ml/gcc-patches/2019-12/msg00173.html
the real fix for the XFAILs in acle/general-c++/gnu_vectors_*.C is to
make same_type_p return false for two types if one is gnu_vector_type_p
and the other isn't. This patch does that and fixes the fallout.
Originally I'd tried to make it so that "X *" and "Y *" are
interconvertible whenever X and Y are, and similarly for
"X &" and "Y &". That doesn't fall out naturally though,
and is different from how -flax-vector-conversions works.
The patch therefore accepts all the consequences of making
X and Y !same_type_p instead of trying to work around them.

typedef unsigned int v4si __attribute__ ((vector_size(16)));
typedef unsigned char v16qi __attribute__ ((vector_size(16)));
extern v16qi x;
v4si &y = reinterpret_cast<v4si>(x);

The patch attempts to fix that by calling rvalue on the input to the
conversion, so that the tree looks the same as for:
extern v16qi x;
v4si &y = (v4si)x;

libgomp/test: Fix compilation for build sysroot
Fix a problem with the libgomp testsuite using a method to determine
the compiler to use resulting in the tool being different from one the
library has been built with, and causing a catastrophic failure from the
lack of a suitable `--sysroot=' option where the `--with-build-sysroot='
configuration option has been used to build the compiler resulting in
the inability to link executables.
Address this problem by defining the compiler to use, via the
GCC_UNDER_TEST TCL variable, set in the DejaGNU configuration file from
$CC by autoconf, which will have all the required options set for the
target compiler to build executables in the environment configured,
removing failures like:
.../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory
.../bin/riscv64-linux-gnu-ld: cannot find -lm
.../bin/riscv64-linux-gnu-ld: cannot find -lpthread

testsuite: Fix run-time tracking down of `libgcc_s'
Fix a catastrophic libgo testsuite failure in cross-compilation where
the shared `libgcc_s' library cannot be found by the loader at run time
in build-tree testing and consequently all test cases fail the execution
stage, giving output (here with the `x86_64-linux-gnu' host and the
`riscv64-linux-gnu' target, with RISC-V QEMU in the Linux user emulation
mode as the target board) like:
spawn qemu-riscv64 -E LD_LIBRARY_PATH=.:.../riscv64-linux-gnu/lib64/lp64d/libgo/.libs ./a.exe
./a.exe: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory
FAIL: archive/tar
To do so rework `gcc-set-multilib-library-path' so as not to rely on the
`rootme' TCL variable to have been preset in testsuite invocation, which
only works for the GCC test suites and not for library test suites, and
also use `remote_exec host' rather than `exec' to invoke the compiler in
determination of `libgcc_s' locations, so that the solution works in
remote testing as well while also avoiding the hardcoded limit of the
executable's path length imposed by `exec'.
This is based on an observation that the multilib root directory can be
determined by stripping out the multilib directory in effect as printed
with the `-print-multi-directory' option from the path produced by the
`-print-file-name=' option. And then individual full multilib paths can
be assembled for the other multilibs by appending their respective
multilib directories to the multilib root directory.
Unlike with the old solution the full multilib paths are not checked for
the presence of the shared `libgcc_s' library there, but that is
supposed to be harmless. Also the full multilib path for the multilib
used with the compiler used for testing will now come first, which
should reduce run-time processing in the usual case.
With this change in place test output instead looks like:
spawn qemu-riscv64 -E LD_LIBRARY_PATH=.:.../riscv64-linux-gnu/lib64/lp64d/libgo/.libs:..././gcc/lib64/lp64d:..././gcc/.:..././gcc/lib32/ilp32:..././gcc/lib32/ilp32d:..././gcc/lib64/lp64 ./a.exe
PASS
PASS: archive/tar
No summary comparison, because the libgo testsuite does not provide one
in this configuration for some reason, however this change improves
overall results from 0 PASSes and 159 FAILs to 133 PASSes and 26 FAILs.

PR c++/92745 - bogus error when initializing array of vectors.
In r268428 I changed reshape_init_r in such a way that when it sees

the initializer:
+ else if (COMPOUND_LITERAL_P (stripped_init)
...
+ ++d->cur;
+ gcc_assert (!BRACE_ENCLOSED_INITIALIZER_P (stripped_init));
+ return init;
But as this test shows, that's incorrect: if TYPE is an array, we need
to proceed to reshape_init_array_1 which will iterate over the array
initializers:
6006 /* Loop until there are no more initializers. */
6007 for (index = 0;
6008 d->cur != d->end && (!sized_array_p || index <= max_index_cst);
6009 ++index)

and update d.cur accordingly. In other words, when reshape_init gets
{{col[0][0], col[1][0], col[2][0], col[3][0]},
{col[0][1], col[1][1], col[2][1], col[3][1]},
{col[0][2], col[1][2], col[2][2], col[3][2]},

{col[0][1], col[1][1], col[2][1], col[3][1]}
and return; we need to iterate, so that d.cur ends up being properly
updated, and after all initializers have been seen, points to d.end.
Currently we skip the loop, wherefore we hit this:

libstdc++: Add inline to maybe-constexpr functions (PR 92927)
Originally these functions were always inline. I changed them in r277342
to be always constexpr, then in r277588 changed them to be constexpr for
C++14, but I didn't restore the 'inline' for C++11. That leads to linker
errors when libstdc++.so is built unoptimized, because those functions
don't get instantiated in src/c++11/string-inst.o

[AArch64] Fix handling of npatterns>1 constants for partial SVE modes
For partial SVE vectors of element X, we want to treat duplicates
of single X elements in the same way as for full vectors of X.
But if a constant instead contains a repeating pattern of X elements,
the transition from one value to the next must happen at container
boundaries rather than element boundaries. E.g. a VNx4HI should
in that case contain the same number of constants as a VNx4SI.
Fixing this means that we need a reinterpret from the container-based
mode to the partial mode; e.g. in the above example we need a
reinterpret from VNx4SI to VNx4HI. We can't use subregs for that
because they're forbidden by aarch64_can_change_class_mode; we should
handle them in the same way as for big-endian instead.

* config/aarch64/aarch64.c (aarch64_simd_valid_immediate): When

There were several overlapping PRs about failure to clean up fully
constructed subobjects when an exception is thrown during aggregate
initialization of a temporary. I fixed this for non-temporaries in the
