Hi Will I have a question about sdiv/ udiv instructions : In armv7 A/R TRM, it said sdiv/udiv will cause Divide by zero as undefined exception or just return zero (decided by implementation) .
So in kernel , should we need register a undef hook to Get this undef exception and send SIGFPE to user space Process ?
