8e09a12f01 [libgomp, nvptx] Fall back to cuLinkAddData/cuLinkCreate if _v2 not found
Cuda driver api functions cuLinkAddData and cuLinkCreate are available starting
version 5.5.  In version 6.5, they are remapped onto _v2 versions.

The dlopen interface of the libgomp nvptx plugin uses the _v2 versions, so it
won't work with a cuda driver with driver api version lower than 6.5.

This patch fixes the problem by testing for the presence of the _v2 versions,
and falling back to the original versions in case of absence of the _v2
versions.

Build on x86_64 with nvptx accelerator and reg-tested libgomp, both with and
without --without-cuda-driver.

cedd9bd016 [libgomp, nvptx] Allow cuGetErrorString to be NULL
Cuda driver api function cuGetErrorString is available in version 6.0 and
higher.

Currently, when the driver that is used does not contain this function, the
libgomp nvptx plugin will not build (PLUGIN_NVPTX_DYNAMIC == 0) or run
(PLUGIN_NVPTX_DYNAMIC == 1).

This patch fixes this problem by testing for the presence of the function, and
handling absence.

Build on x86_64 with nvptx accelerator and reg-tested libgomp, both with and
without --without-cuda-driver.

b113af959c [libgomp, nvptx] Remove hard-coded const in nvptx_open_device
CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR is defined in cuda driver
api version 6.0 and higher.

Currently nvptx_open_device uses a hard-coded constant instead.

This patch fixes that by:
- defining CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR to the hardcoded
  constant at toplevel, if not present in cuda.h, and
- using CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR in nvptx_open_device

94767dacea [libgomp, nvptx] Note that cuGetErrorString is in CUDA_VERSION >= 6000
Cuda driver api function cuGetErrorString is available in version 6.0 and
higher.

This patch:
- removes a comment saying the declaration is not available in cuda.h 6.0
- fixes the presence test to use CUDA_VERSION < 6000
- moves the declaration to toplevel

8cc6307c88 S/390: Remove TARGET_CPU_ZARCH
TARGET_CPU_ZARCH allowed to distinguish between g5/g6 and newer
machines.  Since the former are now gone, we can assume that
TARGET_CPU_ZARCH is always true.  As a side-effect, branch splitting
is now completely gone.  Some parts of literal pool splitting are also
gone, but it's still there: we need to support it because floating
point and vector instructions still cannot use relative addressing.

9be4d77249 libgo: uncomment trace.Stop() call in testing package
Fix up the testing package to insure that execution traces
    work properly (e.g. "-test.trace=<XXX>" command line option). The
    call to stop tracing and emit the output file was stubbed out.

4663b943c6 [AArch64] Fix -mlow-precision-div (PR 86838)
The "@" handling broke -mlow-precision-div, because the scalar forms of
the instruction were provided by a pattern that also provided FRECPX
(and so were parameterised on an unspec code as well as a mode),
while the SIMD versions had a dedicated FRECPE pattern.  This patch
moves the scalar FRECPE handling to the SIMD pattern too (as for FRECPS)
and uses a separate pattern for FRECPX.

The convention in aarch64-simd-builtins.def seemed to be to add
comments only if the mapping wasn't obvious (i.e. not just sticking
"aarch64_" on the beginning and "<mode>" on the end), so the patch
deletes the reference to the combined pattern instead of rewording it.

There didn't seem to be any coverage of -mlow-precision-div in the
testsuite, so the patch adds some tests for it.

1d1b732865 PR libstdc++/86861 Meet precondition for Solaris memalign
Solaris memalign requires alignment to be at least sizeof(int), so
increase it as needed.

Also move the check for valid alignments from the fallback
implementation of aligned_alloc into operator new, as it's required for
all of aligned_alloc, memalign, posix_memalign and __aligned_malloc.
This adds a branch to check for undefined behaviour which we could just
ignore, so the check could just be removed. It should certainly be
removed if PR 86878 is implemented to issue a warning about calls with
invalid alignments.

02150de863 [libgomp, nvptx] Handle CUDA_ONE_CALL_MAYBE_NULL
This patch adds handling of functions that may not be present in the cuda
driver.

Such a function can be declared using CUDA_ONE_CALL_MAYBE_NULL in cuda-lib.def,
it can be called with the usual convenience macros, but before calling its
presence needs to be tested using new macro CUDA_CALL_EXISTS.

When using the dlopen interface (PLUGIN_NVPTX_DYNAMIC == 1), we allow
non-present functions by allowing dlsym to return NULL.  Otherwise
(PLUGIN_NVPTX_DYNAMIC == 0) we declare the non-present function to be weak.

Build and reg-tested libgomp on x86_64 with nvidia accelerator, with and without
--disable-cuda-driver, in combination with a trigger patch that adds a
non-existing function foo to cuda-lib.def:
...
CUDA_ONE_CALL_MAYBE_NULL (foo)
...
and declares it in plugin-nvptx.c:
...
CUresult foo (void);
...
and then uses it in nvptx_init after the init_cuda_lib call:
...
  if (CUDA_CALL_EXISTS (foo))
    CUDA_CALL (foo);
...

Also build and reg-tested on x86_64 with nvidia accelerator, with and without
--disable-cuda-driver, in combination with a trigger patch that replaces all
CUDA_ONE_CALLs in cuda-lib.def with CUDA_ONE_CALL_MAYBE_NULL, and guards two
CUDA_CALLs with CUDA_CALL_EXISTS, one for a regular fn, and one for a fn that is
a define in cuda/cuda.h.

	* plugin/plugin-nvptx.c (DO_PRAGMA): Define.
	(struct cuda_lib_s): Add def/undef of CUDA_ONE_CALL_MAYBE_NULL.
	(init_cuda_lib): Add new param to CUDA_ONE_CALL_1.  Add arg to
