To reproduce:
$ cd {build_dir}/gcc && make check

--target_board='unix{-m64\ -march=cascadelake}'"

RUNTESTFLAGS="i386.exp=gcc.target/i386/sse4_1-stv-12.c
--target_board='unix{-m64\ -march=cascadelake}'"
(Please directly reply to this email for question about this report.)
(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.)
