[PATCH] D34144: [CodeGen] Add generic MacroFusion pass.

[Evandro Menezes via Phabricator via llvm-commits]

evandro added inline comments.


================
Comment at: lib/CodeGen/MacroFusion.cpp:123
+      for (const SDep &SI : FirstSU.Succs) {
+        if (!SI.getSUnit() || SI.getSUnit() == &SecondSU)
+          continue;
----------------
`!SI.getSUnit()` seems to be reduntant.
