... and add a minimum amount of offloading testing.
(Leaving aside that 'fwrite' to 'stderr' probably wouldn't work anyway) the
'fwrite' calls in 'libgomp/error.c:GOMP_warning', 'libgomp/error.c:GOMP_error'
drag in 'isatty', which isn't provided by my nvptx newlib build at present, so
we get, for example:
[...]
FAIL: libgomp.c/../libgomp.c-c++-common/declare_target-1.c (test for excess errors)
Excess errors:
unresolved symbol isatty
mkoffload: fatal error: [...]/build-gcc/./gcc/x86_64-pc-linux-gnu-accel-nvptx-none-gcc returned 1 exit status
[...]
..., and many more.
Fix up for recent commit 0d973c0a0d
"openmp: Implement the error directive".
libgomp/
* config/nvptx/error.c (fwrite, exit): Override, too.
* testsuite/libgomp.c-c++-common/error-1.c: Add a minimum amount
of offloading testing.
* testsuite/libgomp.fortran/error-1.f90: Likewise.
