[PATCH] D68191: Simplify function llvm::removeUnreachableBlocks() to avoid (re-)computation.

[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/Local.cpp:2229
   SmallSetVector<BasicBlock *, 8> DeadBlockSet;
   for (Function::iterator I = ++F.begin(), E = F.end(); I != E; ++I) {
     auto *BB = &*I;
----------------
This can now be just `for (BasicBlock &BB : F) {` I think, as we do not modify the BB list
