Do you mean reducing the record-form rotates by 70%? If so, it is great!



================
Comment at: lib/Target/PowerPC/PPCInstrInfo.cpp:1803
+  if (MIOpC == PPC::ANDIo || MIOpC == PPC::ANDIo8 ||
+      MIOpC == PPC::ANDISo || MIOpC == PPC::ANDISo8)
     NewOpC = MIOpC;
----------------
This change seems independent from other part of this patch. So this can be a separate patch.
Also it is nice to add an unit test for this part.
