[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/lib/Target/ARM/MVETailPredication.cpp:169
 
 void MVETailPredication::RevertActiveLaneMask() {
+  if (ActiveLaneMasks.empty())
----------------
I think I'd prefer if you just taught isel legalization to lower llvm.get.active.lane.mask calls, rather than depend on the MVETailPredication pass running before isel.
