[Vitaly Buka via Phabricator via cfe-commits]

vitalybuka added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/SimplifyCFG.cpp:6056
                        SmallPtrSetImpl<BasicBlock *> *LoopHeaders) {
+  const Function *Fn = BB->getParent();
+  if (Fn && Fn->getMetadata("no_simplify_cfg"))
----------------
So maybe Attribute::SanitizeFuzzer for each function with --fsanitizer=fuzzer 
and then

```
if (... getFunction()->hasFnAttribute(Attribute::SanitizeFuzzer))
    return;
```
