[LLVMdev] Instruction MVT::ValueTypes
...PS on the same data.
For the case of MOVAPS vs. MOVAPD vs. MOVDQU (assuming you have a
micro-architecture where there's actually a difference), this can be
achieved by having instruction selection select the right instructions.
For example, find code like this in X86InstrSSE.td:
def : Pat<(alignedloadv2i64 addr:$src),
(MOVAPSrm addr:$src)>, Requires<[HasSSE2]>;
def : Pat<(loadv2i64 addr:$src),
(MOVUPSrm addr:$src)>, Requires<[HasSSE2]>;
and change it to not select MOVAPS for that microarchitecture, for
example.
