--- Comment #11 from Asumu Takikawa <asumu at igalia.com> ---
Thanks for pointing out these issues! I've pushed a new patch that adds the IC paths in `WebAssemblyFunction.cpp`, and also tests them (by looping for the relevant test cases).

> Does this nullable check happen in Wasm's global set? Can we have a test that ensures this exception happens in wasm too?

This check should not be needed at runtime for global set, because Wasm validation should prevent it from compiling if a null argument is passed. I have added a test case that makes sure this validation happens to the end of `testRefGlobalCheck()`.
