Hongtao.liu <crazylht at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |crazylht at gmail dot com --- Comment #1 from Hongtao.liu <crazylht at gmail dot com> --- for sse load/store, with aligned address, movdqu is as fast as movdqa, so i'm thinking that backend can generate only unaligned load/store instructions(which of course may cover up some problems).
