--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Can't reproduce:
$ ./xgcc -B ./ -S -g3 -O3 -std=c99 -march=native -mavx512 pr80377.c
xgcc: error: unrecognized command line option ‘-mavx512’; did you mean
‘-mavx512f’?
$ gcc -S -g3 -O3 -std=c99 -march=native -mavx512 pr80377.c
gcc: error: unrecognized command line option ‘-mavx512’; did you mean
‘-mavx512f’?
The first one is with current gcc trunk, the second one with Fedora
gcc-6.3.1-1.fc25.x86_64.
