Fix SSA update when vectorisation adds a vdef to a read-only loop
This patch fixes an awkward corner case in which:
(a) we apply if-conversion to a loop;
(b) the original scalar loop doesn't have a vdef, and thus doesn't
need a virtual phi;
(c) the vectorised main loop does need a vdef and a virtual phi (see below);
(d) we also vectorise the epilogue; and
(e) the vectorised epilogue still needs a scalar epilogue
The specific case in which (c) applies is if a read-only loop is
vectorised using IFN_LOAD_LANES, which uses clobber statements to
mark the lifetime of the temporary array.
The vectoriser relies on the SSA renamer to update virtual operands.
All would probably be well if it postponed this update until after
it had vectorised both the main loop and the epilogue loop. However,
when vectorising the epilogue, vect_do_peeling does:
create_lcssa_for_virtual_phi (loop);
update_ssa (TODO_update_ssa_only_virtuals);
(with "loop" in this case being the to-be-vectorised epilogue loop).
So the vectoriser puts the virtual operand into SSA form for the
vectorised main loop as a separate step, during the early stages
of vectorising the epilogue.
I wasn't sure at first why that update_ssa was there. It looked
initially like it was related to create_lcssa_for_virtual_phi,
which seemed strange when create_lcssa_for_virtual_phi keeps the
SSA form up-to-date. But before r241099 it had the following comment,
which AFAICT is still the reason:
/* We might have a queued need to update virtual SSA form. As we
delete the update SSA machinery below after doing a regular
incremental SSA update during loop copying make sure we don't
lose that fact.
??? Needing to update virtual SSA form by renaming is unfortunate
but not all of the vectorizer code inserting new loads / stores
properly assigns virtual operands to those statements. */
The patch restores that comment since IMO it's helpful.
(a), (d) and (e) mean that we copy the original un-if-converted scalar
loop to act as the scalar epilogue. The update_ssa above means that this
copying needs to cope with any new virtual SSA names in the main loop.
The code to do that (reasonably) assumed that one of two things was true:
(1) the scalar loop and the vector loops don't have vdefs, and so no
virtual operand update is needed. The definition that applies
on entry to the loops is the same in all cases.
(2) the scalar loop and the vector loops have virtual phis, and so --
after applying create_lcssa_for_virtual_phi on the to-be-vectorised
epilogue loop -- the virtual operand update can be handled in the
same way as for normal SSA names.
But (b) and (c) together mean that the scalar loop and the
still-to-be-vectorised epilogue loop have no virtual phi that (2)
can use. We'd therefore keep the original vuses when duplicating,
rather than updating them to the definition that applies on exit
from the epilogue loop. (Since the epilogue is still unvectorised
and has no vdefs, the definition that applies on exit is the same
as the one that applies on entry.)
This patch therefore adds a third case: the scalar loop and
to-be-vectorised epilogue have no virtual defs, but the main loop does.

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.

[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.

extern v16qi x;

ICEs with:

This started with r260780, which had the effect of making lvalue_kind
look through VIEW_CONVERT_EXPR in all cases, not just for location
wrappers. This also means that:
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);
is now valid despite the result of the cast being an rvalue.
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;
which is already handled correctly.

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
.../bin/riscv64-linux-gnu-ld: cannot find -lc
.../bin/riscv64-linux-gnu-ld: cannot find -latomic

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
a nested { } in a CONSTRUCTOR with missing braces, it just returns
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)
6010 {
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][3], col[1][3], col[2][3], col[3][3]}}
we recurse on the first element:
{col[0][0], col[1][0], col[2][0], col[3][0]}
and we can't just move d.cur to point to
{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:
6502 /* Make sure all the element of the constructor were used. Otherwise,
6503 issue an error about exceeding initializers. */
6504 if (d.cur != d.end)
