--- Comment #8 from Jason Merrill <jason at gcc dot gnu.org> --- Created attachment 37774 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37774&action=edit loop inversion sketch This patch does loop inversion sufficient for scimark. It will break constexpr, but might be useful for looking at the LTO issue.
