New issue 3039 by [email protected]: ARM: Division in simulator
breaks for certain inputs
http://code.google.com/p/v8/issues/detail?id=3039
Running this script under the simulator (ARM in this case, but others may
also be broken) causes a Floating point exception.
function do_div(x, y) {
return (x / y) | 0;
}
do_div(1, 1);
%OptimizeFunctionOnNextCall(do_div);
do_div(1, 1);
do_div(-2147483648, -1);
I think this is due to *div implementation in the simulator using integer
division, and MIN_INT / -1 being undefined in C.
Reproducible on x86 using GCC 4.6.x and 4.7.x. Correct result is obtained
when running natively on ARM hardware.
