[PATCH] D74775: [Utils][x86] add an option to reduce scrubbing of shuffles with memops

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I think we we discussed recently about always exposing stack math - I don't care about seeing constant labels but tbh I think we probably need to see all register based pointer math on x86 (maybe with some way to merge X86/X64 registers?).



================
Comment at: llvm/test/CodeGen/X86/extractelement-load.ll:233
 ; X32-SSE2-NEXT:    cmpeqss %xmm0, %xmm1
-; X32-SSE2-NEXT:    movss {{.*#+}} xmm2 = mem[0],zero,zero,zero
+; X32-SSE2-NEXT:    movss {{\.LCPI.*}}, %xmm2 # xmm2 = mem[0],zero,zero,zero
 ; X32-SSE2-NEXT:    andps %xmm1, %xmm2
----------------
this is a constant - ideally we'd hide the LCPI and the comment would be the actual constant value
