Needed some manual fixes: AMDGPU/asan_instrument_generic_address_space.ll dynamic-shadow-darwin.ll lifetime.ll stack-poisoning-byval-args.ll global_metadata_windows.ll asan-masked-load-store.ll stack-poisoning-and-lifetime.ll stack-poisoning-and-lifetime-be.ll This included some of the worst opaquify breakages I've seen. The tests were dependent on 0 indexed GEPs, and had check lines directly checking pointee types.
