@lkail yes, new contributor here so if you can land it or tell me how to go about that? Thanks

vddvss updated the diff for D69497: [PowerPC] Fix MI peephole optimization for splats.

See attached for an updated diff. This also changes the name of FeedImmed to DefImmed to be congruent with DefReg[12].

vddvss updated the diff for D69497: [PowerPC] Fix MI peephole optimization for splats.

Per @jsji's suggestion, this checks if the operands to DefMI are both the same virtual register, which enables optimization in more cases.

vddvss updated the diff for D69497: [PowerPC] Fix MI peephole optimization for splats.

Updated revision. Note, I also had to update test/CodeGen/PowerPC/load-shuffle-and-shuffle-store.ll since this will omit the optimization in some of those cases.

Thanks. Should have checked :) This issue is causing buffer overflows in some applications compiled with Clang 9, so hopefully your fix can be ok'd soon.
