--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, if the clobbers (unlike sets) are there just for -fipa-ra purposes, can't
we drop the clobbers from the pattern and only add them during output (i.e.
replace "vzeroupper" with C code that first modifies the pattern if flag_ipa_ra
and then returns "vzeroupper"?
