[PATCH] D133676: [X86] Simplify isReplaceable (NFC)

[Phoebe Wang via Phabricator via llvm-commits]

pengfei added inline comments.


================
Comment at: llvm/lib/Target/X86/X86OptimizeLEAs.cpp:464
     // the LEA is not replaceable.
-    if (!isIdenticalOp(MI.getOperand(MemOpNo + X86::AddrBaseReg), MO))
+    if (&MO != &MI.getOperand(MemOpNo + X86::AddrBaseReg))
       return false;
----------------
This cannot prevent def register been used by other operands at the same time.
