[PATCH] D59626: Add MachineDCE pass after RenameIndependentSubregs

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: lib/CodeGen/DeadMachineInstructionElim.cpp:193-197
+  for (auto Reg : RecalcRegs) {
+    LIS->removeInterval(Reg);
+    if (!MRI->reg_empty(Reg))
+      LIS->createAndComputeVirtRegInterval(Reg);
+  }
----------------
Can you just use shrinkToUses?
