--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 46253 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46253&action=edit gcc9-pr90257.patch Untested patch that fixes PR90178 even when the reversion of reversion of reversion in lra-spills.c is reverted. For the trunk, we could as well replace the lra-spills.c change with richi's dce change or whatever else. Just it seems to be wrong to rely on unoptimal IL to perform proper optimizations.
