[PATCH] D89781: [NPM] Port -mergereturn to NPM

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/UnifyFunctionExitNodes.cpp:125
+                                                  FunctionAnalysisManager &AM) {
+  if (!unifyUnreachableBlocks(F) && !unifyReturnBlocks(F))
+    return PreservedAnalyses::all();
----------------
this won't run `unifyReturnBlocks()` if `unifyUnreachableBlocks()` returns true, is that expected?
