Warnings would be good. My warning still holds: there are modes of compilation on some machines where you can't clobber all registers without causing reload failures. This is why Jeff didn't fix this in 1999. So, if we really do want to clobber "all" registers in basic asm it'll take a lot of work. Andrew.
