--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Can I ask you to see whether -O3 -fno-tree-vectorize avoids the issue and
whether -O3 -fno-vect-cost-model makes the issue appear in more versions? It
could be that this is a resolved issue that awaits backporting of a fix (or
where backporting is too difficult).
I can confirm the -O3 -march=core-avx2 failure with GCC 10 and success with GCC
11.
