This revision is now accepted and ready to land.
LGTM.
Just curious: why no test affected. Is the COPY eliminated laterly?
================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:34573
// FirstInsertedMBB (the True operand of the SELECT_CC/CMOV nodes).
MIB.addReg(FirstCMOV.getOperand(2).getReg()).addMBB(FirstInsertedMBB);
- // Copy the PHI result to the register defined by the second CMOV.
----------------
Use `Op2Reg`?
