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)
