--- Comment #6 from Dimitri Gorokhovik <dimitri.gorokhovik at free dot fr> --- Thank you Andrew, I indeed see now the early-clobber effect of this code. It isn't that we don't read documentation (we do time to time), rather our real asm statement has more output ops and more elementary instructions in the template, so the early-clobber effect doesn't jump to the eye quite as easily. I guess we have to mask all output ops as early clobbers.
