amker at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |amker at gcc dot gnu.org --- Comment #3 from amker at gcc dot gnu.org --- I have seen potential improvement of bzip/gzip on arm 32. It relates to addressing mode which affecting loop invariant hoisting in kernel loop of these two benchmarks. I once had a patch but didn't follow up that. I think it's worthy of methodical investigation, rather than case by case changes. Thanks, bin
