I may have gotten that wrong, but I thought that the warning message was
coming from the back-end by trying the same thing over and over again.

It's true that the front-end should only pass recognizable CPUs (as I said
earlier, it should convert to the default CPU if not), but I was under the
impression that this could also happen with other tools (llc, etc) that
didn't use Clang's driver. Don't take my opinion on this as kosher, it
certainly isn't.


Sounds like something that should be discussed with folks on
