--- Comment #30 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 63554 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=63554&action=edit unincluded testcase The preprocessed sources no longer works. GCC 7 and GCC 15 produce comparable results for me with -O3 -mavx on a Zen4 machine. I don't have a working GCC 5 to cross-check with that. I attached un-included source (with Eigen still included) that works with GCC 7 and 15.
