Fair enough. Let's not complicate things just to avoid a few nops.

That does make me wonder about RIP-relative addressing in alternatives
too. Particularly anything where we let gcc pick addressing modes. I
guess we don't have any, but maybe this branch issue and possible RIP
addressing is something that objtool could be taught to warn about?
