libgomp: Use libnuma for OpenMP's partition=nearest allocation trait
caused
with GCC configured with
../../gcc/configure
--prefix=/export/users/haochenj/src/gcc-bisect/master/master/r14-2462/usr
--enable-clocale=gnu --with-system-zlib --with-demangler-in-ld
--with-fpmath=sse --enable-languages=c,c++,fortran --enable-cet --without-isl
--enable-libmpx x86_64-linux --disable-bootstrap
To reproduce:
$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check
RUNTESTFLAGS="c++.exp=libgomp.c-c++-common/alloc-11.c
--target_board='unix{-m32}'"
$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check
RUNTESTFLAGS="c++.exp=libgomp.c-c++-common/alloc-11.c
--target_board='unix{-m32\ -march=cascadelake}'"
$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check
RUNTESTFLAGS="c++.exp=libgomp.c-c++-common/alloc-12.c
--target_board='unix{-m32}'"
$ cd {build_dir}/x86_64-linux/libgomp/testsuite && make check
RUNTESTFLAGS="c++.exp=libgomp.c-c++-common/alloc-12.c
--target_board='unix{-m32\ -march=cascadelake}'"
(Please do not reply to this email, for question about this report, contact me
at haochen dot jiang at intel.com.) (If you met problems with cascadelake
related, disabling AVX512F in command line might save that.) (However, please
make sure that there is no potential problems with AVX512.)
