Ok, so this "cmplwi cr0, rX, ppc_exc_lock_std@sdarel" is illegal, since
ppc_exc_lock_std@sdarel is signed and the immediate is unsigned 16-bit? The
assembler doesn't issue a warning about this.
Exists there a way to rescue this cmplwi hack without relaxing the overflow
checks?
Hm, sorry, it was surprisingly simple. This works:
"cmplwi cr0, rX, ppc_exc_lock_std@sdarel@l"
I was not aware that you can add several @ in a row.
