--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Roger Sayle <sa...@gcc.gnu.org>: https://gcc.gnu.org/g:9f66753ef48f37729a88735ae1a2bf2d2558e69f commit r14-2743-g9f66753ef48f37729a88735ae1a2bf2d2558e69f Author: Roger Sayle <ro...@nextmovesoftware.com> Date: Mon Jul 24 12:34:23 2023 +0100 [Committed] PR target/110787: Revert QImode offsets in {zero,sign}_extract. My recent patch to use QImode for bit offsets in ZERO_EXTRACTs and SIGN_EXTRACTs in the i386 backend shouldn't have resulted in any change behaviour, but as reported by Rainer it produces a bootstrap failure in gm2. This reverts the problematic patch whilst we investigate the underlying cause. Committed as obvious. 2023-07-23 Roger Sayle <ro...@nextmovesoftware.com> gcc/ChangeLog PR target/110787 PR target/110790 Revert patch. * config/i386/i386.md (extv<mode>): Use QImode for offsets.
