--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Richard Earnshaw <rearn...@gcc.gnu.org>: https://gcc.gnu.org/g:98032b3e320a5b63309d6a843f6e97fb0506953a commit r11-11251-g98032b3e320a5b63309d6a843f6e97fb0506953a Author: Richard Earnshaw <rearn...@arm.com> Date: Thu Feb 22 16:47:20 2024 +0000 arm: fix ICE with vectorized reciprocal division [PR108120] The expand pattern for reciprocal division was enabled for all math optimization modes, but the patterns it was generating were not enabled unless -funsafe-math-optimizations were enabled, this leads to an ICE when the pattern we generate cannot be recognized. Fixed by only enabling vector division when doing unsafe math. gcc: PR target/108120 * config/arm/neon.md (div<VCVTF:mode>3): Rename from div<mode>3. Gate with ARM_HAVE_NEON_<MODE>_ARITH. gcc/testsuite: PR target/108120 * gcc.target/arm/neon-recip-div-1.c: New file. (cherry picked from commit 016c4eed368b80a97101f6156ed99e4c5474fbb7)
