[PATCH] D122215: [WebAssembly] Initial support for reference type externref in clang

[Alex Bradbury via Phabricator via cfe-commits]

asb added a comment.

I've left one minor comment. My other suggestion would be to absorb in the semantic restrictions work from here <https://gist.github.com/asb/b8701efe35cf99bc8fd606b9ca984337>.



================
Comment at: llvm/lib/IR/Type.cpp:307
 
+Type *Type::getWasm_ExternrefTy(LLVMContext &C) {
+  // pointer to opaque struct in addrspace(10)
----------------
With the move to opaque pointers, I think this and getWasm_FuncRefTy could be updated to just return a pointer to addrspace 10 and 20 respectively?
