Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|middle-end |testsuite --- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- Ok, the backport cannot possibly have affected aarch64 so the issue is latent and not a regression there. Testsuite issue. It looks like parameter passing of typedef long double a __attribute__((vector_size (16))); is "not implemented" on aarch64. I'll change the testcase to exclusively run on x86_64 / i?86 on the branch.
