code that cross integer / floating point domains (e.g. generate pxor / pand for logical ops on floating point value, movdqa to load / store floating point SSE values). Given that, it's better to use movaps instead of movdqa and movups instead of movdqu. They have the same latency but the "aps" variants are one byte shorter. If the domain crossing problem is a real performance issue, then we will have to fix it with dynamic programming based isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40076 91177308-0d34-0410-b5e6-96231b3b80d8
