--- Comment #1 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Kewen Lin <li...@gcc.gnu.org>: https://gcc.gnu.org/g:6660904c3f5872262f466b5cbbd48fb11e9fe966 commit r14-7091-g6660904c3f5872262f466b5cbbd48fb11e9fe966 Author: Kewen Lin <li...@linux.ibm.com> Date: Tue Jan 9 23:06:13 2024 -0600 rs6000: Eliminate zext fed by vclzlsbb [PR111480] As PR111480 shows, commit r14-4079 only optimizes the case of vctzlsbb but not for the similar vclzlsbb. This patch is to consider vclzlsbb as well and avoid the failure on the reported test case. It also simplifies the patterns with iterator and attribute. PR target/111480 gcc/ChangeLog: * config/rs6000/vsx.md (VCZLSBB): New int iterator. (vczlsbb_char): New int attribute. (vclzlsbb_<mode>, vctzlsbb_<mode>): Merge to ... (vc<vczlsbb_char>zlsbb_<mode>): ... this. (*vctzlsbb_zext_<mode>): Rename to ... (*vc<vczlsbb_char>zlsbb_zext_<mode>): ... this, and extend it to cover vclzlsbb.
