Why not?  Emotional question-begging ("torture") aside, that is.

(Well, strictly, no hardware generates SIGFPE, which is an OS thing;
the hardware just traps, with the kernel doing the signal generation.
But I don't see any reason the conditional trap to the kernel has to be
part of the divide instruction; a "trap if OV set" instruction after
the divide proper seems perfectly reasonable to me.)
