[PATCH] D90304: [GlobalISel] Introduce optimal variant of regbankselect

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/RegBankSelect.cpp:1306
+      auto MO = MI.getOperand(i);
+      if (!isMachineOperandWithVirtualReg(MO)) {
+        continue;
----------------
I think checking if this is virtual is redundant; any instruction subject to rgebank select should not have physical register operands
