[PATCH] D130919: [MRI] isConstantPhysReg should also check if the register is clobbered by a RegMask

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/RegUsageInfoPropagate.cpp:147-149
+  if (Changed)
+    MF.getRegInfo().recollectUsedPhysRegMask();
+
----------------
Won't this be reflected in the regmask updates (BTW I think this pass needs to be changed to directly modify the regmasks in the instruction instead of the analysis)?
