To reproduce:
$ cd {build_dir}/gcc && make check
RUNTESTFLAGS="gomp.exp=gcc.dg/gomp/max_vf-1.c --target_board='unix{-m32\
-march=cascadelake}'"
$ cd {build_dir}/gcc && make check
RUNTESTFLAGS="gomp.exp=gcc.dg/gomp/max_vf-1.c --target_board='unix{-m64\
-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.)
