$ cd {build_dir}/gcc && make check

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

--target_board='unix{-m64\ -march=cascadelake}'"
(Please do not reply to this email, for question about this report, contact me

(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.)
