[PATCH] D70240: [ARM][ReachingDefs] Remove dead code in loloops.

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added inline comments.


================
Comment at: llvm/lib/Target/ARM/ARMLowOverheadLoops.cpp:348
+
+  // First, find the block that looks like the preheader.
+  MachineBasicBlock *MBB = ML->getHeader();
----------------
Would `MachineLoopInfo::findLoopPreheader()` be useful here?
