--- Comment #6 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:37876976b0511ec96741f638f160874f2added0e commit r11-7121-g37876976b0511ec96741f638f160874f2added0e Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Feb 5 10:39:03 2021 +0100 i386: Fix up TARGET_QIMODE_MATH for many AMD CPU tunings [PR98957] As written in the PR, TARGET_QIMODE_MATH was meant to be set for all tunings and it was the case for GCC <= 7, but as the number of PROCESSOR_* enumerators grew, some AMD tunings (which are at the end of the list) over time got enumerators with values >= 32 and TARGET_QIMODE_MATH became disabled for them, in GCC 8 for 2 tunings, in GCC 9 for 7 tunings, in GCC 10 for 8 tunings, and on the trunk for 11 tunings. The following patch fixes it by using uhwis rather than uints and gives them also symbolic names. 2021-02-05 Jakub Jelinek <ja...@redhat.com> PR target/98957 * config/i386/i386-options.c (m_NONE, m_ALL): Define. * config/i386/x86-tune.def (X86_TUNE_BRANCH_PREDICTION_HINTS, X86_TUNE_PROMOTE_QI_REGS): Use m_NONE instead of 0U. (X86_TUNE_QIMODE_MATH): Use m_ALL instead of ~0U.
