--- Comment #6 from H.J. Lu <hjl.tools at gmail dot com> --- (In reply to Yichao Yu from comment #5) > It’s wrong when running on a target that has avx512f. The unoptimuzed > version will call the correct foo but the unoptimized case won’t. > > As I said, this is an issue when the total targets are different between the > callee and caller. Your testcase has nested function multi-versioning. I don't think it works at all. I opened PR 95793.
