[PATCH] D129561: [RS4GC] Fix over-restrictive assert in atomic memcpy/move handling

[Artur Pilipenko via Phabricator via llvm-commits]

apilipenko added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/RewriteStatepointsForGC.cpp:1705
       auto GetBaseAndOffset = [&](Value *Derived) {
-        assert(PointerToBase.count(Derived));
         unsigned AddressSpace = Derived->getType()->getPointerAddressSpace();
----------------
I suggest handling the undef case explicitly. Just return undef if the input is undef.
