[PATCH] D63816: [ARM] WLS/LE Code Generation

[Dave Green via Phabricator via llvm-commits]

dmgreen added inline comments.


================
Comment at: lib/Target/ARM/ARMLowOverheadLoops.cpp:320
+    Start = ExpandLoopStart(ML, Start);
+    RemoveDeadBranch(Start);
+    End = ExpandLoopEnd(ML, Dec, End);
----------------
These is something called ARMBaseInstrInfo::analyzeBranch which can help optimise away these unconditional fallthroughs too, if it can be made to work with loloop instructions.
