EXTERN PROC isn't really well documented in MSVC, so after poking around it seems as if it's just a regular extern symbol. Interestingly enough, under MSVC the following is allowed: extern foo:proc mov eax, foo MSVC will output: mov eax, 0 while llvm-ml will currently output: mov eax, dword ptr [foo] (since foo is an extern) Arguably, llvm-ml's output makes more sense, even though it's inconsistent with MSVC ml. However, since moving an extern proc symbol to a register doesn't really make sense in the first place, we'll treat it as undefined behavior for now.
