--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I said that above, -mdejagnu-cpu=power10 isn't passed to the effective target
snippet compilation, so it doesn't test whether the test with
-mdejagnu-cpu=power10 will be power10, but rather tests whether the compiler is
configured to default to -mcpu=power10 or perhaps whether this is
--target_board=unix/-mcpu=power10 testing:
