[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/SimplifyCFGPass.cpp:248-251
+  if (F.hasFnAttribute(Attribute::OptForFuzzing))
+    Options.setSimplifyCondBranch(false).setFoldTwoEntryPHINode(false);
+  else
+    Options.setSimplifyCondBranch(true).setFoldTwoEntryPHINode(true);
----------------
the changes in this file shouldn't be necessary any more


================
Comment at: llvm/lib/Transforms/Utils/SimplifyCFG.cpp:2419
+  const Function *Fn = BB->getParent();
+  if (Fn && Fn->hasFnAttribute(Attribute::OptForFuzzing))
+    return false;
----------------
Fn should never be null, ditto below
