Before emitting the final compiled code, all the pseudo instructions must be expanded to real instructions. If you're seeing that error, it means that something was not expanded.

Could you get it to print out the instruction when it happens? (just change the line above the error message to print it out to errs()).
It basically means that a pseudo wasn't lowered to something that the jit can output before the jit was run. Is this on ToT?
