--- Comment #11 from Robin Dapp <rdapp at gcc dot gnu.org> --- Thanks for figuring that out. No idea if the pattern is the problem, most likely not? I rather suppose there is still a missing fixup somewhere in the vectorizer that I didn't encounter with my testing. So the testsuite without bootstrap is really unchanged? We still have a SPEC build problem on aarch64 caused by my initial patch that's caused by not handling COND_OPs in vect_bool_pattern somewhere. I didn't get to checking that yet but will soon. Maybe there is something similar here?
