[PATCH] D25455: Document potential implementation of CFI in hardware.

[Peter Collingbourne via llvm-commits]

pcc added a comment.

I think this would benefit from an assembly code listing for a couple of cases (e.g. all-ones, bit vector).

One concern I have is that in the case where we have a bit vector lookup, the code would end up computing the byte offset redundantly with the instruction, which would somewhat diminish the code size benefits here.
