--- Comment #5 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- (In reply to Christophe Lyon from comment #4) > 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 Works for: -Os -fdump-tree-ivopts -save-temps -S -march=armv8-a -mfpu=crypto-neon-fp-armv8 -Os -fdump-tree-ivopts -save-temps -S -mthumb -march=armv8-a -mfpu=crypto-neon-fp-armv8 -Os -fdump-tree-ivopts -save-temps -S -mthumb -march=armv7ve+simd -mfpu=auto Similarly for ssa-dom-thread-7.c. Perhaps someone else can reproduce. And just to be clear, it would be easier if someone could reproduce with a cc1 / gcc command line, and not by pointing us to some table in a web page.
