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.

This test:
typedef unsigned int v4si __attribute__ ((vector_size(16)));
typedef unsigned char v16qi __attribute__ ((vector_size(16)));
extern v16qi x;
v4si &y = x;
ICEs with:
a.c:4:11: internal compiler error: in convert_like_real, at cp/call.c:7670
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.

Add generic support for the OpenACC 2.6 `acc_get_property' and
`acc_get_property_string' routines, as well as full handlers for the
host and the NVPTX offload targets and minimal handlers for the HSA,
Intel MIC, and AMD GCN offload targets.
Included are C/C++ and Fortran tests that, in particular, print
the property values for acc_property_vendor, acc_property_memory,
acc_property_free_memory, acc_property_name, and acc_property_driver.
The output looks as follows:
Vendor: GNU
Name: GOMP
Total memory: 0
Free memory: 0
Driver: 1.0
with the host driver (where the memory related properties are not
supported for the host device and yield 0, conforming to the standard)
and output like:

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

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

overall results from 0 PASSes and 159 FAILs to 133 PASSes and 26 FAILs.

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)
6505 {
