[PATCH] D124571: Avoid strict aliasing violation on type punning inside llvm::PointerIntPair

[Argyrios Kyrtzidis via Phabricator via llvm-commits]

akyrtzi added inline comments.


================
Comment at: llvm/include/llvm/ADT/PointerIntPair.h:46
+
+  Ptr *getPointerAddress() { return reinterpret_cast<Ptr *>(Data); }
+  const Ptr *getPointerAddress() const { return reinterpret_cast<Ptr *>(Data); }
----------------
I'm wondering if the standard "blesses" this use of `reinterpret_cast` or whether it's some kind of UB..
