[PATCH] D21768: Support CFI for WebAssembly target

[Peter Collingbourne via llvm-commits]

Thanks, but that only raises more questions.

What is an "index"? Is it something that can be called, like a function pointer?

If that's the case, and indexes start from zero, how do you resolve conflicts between indexes in dynamically loaded modules? Or does your design assume no dynamic loading?

(Also, how do you represent null function pointers if indexes start at zero?)
