--- Comment #12 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:da24fce323eaf088239e0f900dd23f6b05d552c1 commit r12-7654-gda24fce323eaf088239e0f900dd23f6b05d552c1 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Mar 15 10:24:22 2022 +0100 i386: Use no-mmx,no-sse for LIBGCC2_UNWIND_ATTRIBUTE [PR104890] Regardless of the outcome of the general-regs-only stuff in x86gprintrin.h, apparently general-regs-only is much bigger hammer than no-sse, and e.g. using 387 instructions in the unwinder isn't a big deal, it never needs to realign the stack because of it. So, the following patch uses no-sse (and adds no-mmx to it, even when not strictly needed). 2022-03-15 Jakub Jelinek <ja...@redhat.com> PR target/104890 * config/i386/i386.h (LIBGCC2_UNWIND_ATTRIBUTE): Use no-mmx,no-sse instead of general-regs-only.
