--- Comment #4 from Christophe Lyon <clyon at gcc dot gnu.org> --- If I'm not mistaken, if you click on "REGRESSED" for that specific line, you'll see that only ssa-dom-thread-7.c actually regressed with the corresponding flags. For ivopts-4.c, if seems you need -mthumb and one of these values for -march: armv7-a+mp+sec+neon-fp16 armv7ve+simd armv7-a+mp+sec+vfpv3-d16-fp16 armv8-a+crc+simd+crypto (possibly with -mfpu=auto) or -march=armv8-a -mfpu=crypto-neon-fp-armv8
