We're not, no. We're talking about the reasons given to justify the claim that a pseudo-insn emitted by the compiler is not "suspicious". To say those reasons are "sound" is to say that my initial objection to the pseudo-insn was answered by the explanation proffered and is now obviously invalid. I think it's a matter of further discussion, not that it is, at this point, obviously valid. (As it turns out, my objection was valid, at least in part. A small number of the problematic assumptions are now, apparently, no longer being emitted.) Pip
