I'm trying to get Smalltalk from the ports collection working, but I'm running
into a recurring problem with floating point handling, ending up with an
exception and a core dump. I've reduced the problem to the following simple
program:
#include <floatingpoint.h>
main()
{
double num, base, exponent;
fp_except_t mask;
mask = fpgetmask();
fpsetmask(mask & ~(FP_X_INV|FP_X_OFL));
base = 10; exponent = 1000;
num = pow(base, exponent);
}
Unless I'm missing something, an fp exception shouldn't be happening because
I have them disabled. Compiling with -mieee or -mfp-regs makes no difference,
still dumps. If I do an outright fpsetmask(0) it still dumps.
For what it's worth, the preceeding code runs fine on an intel box.
Anyone have any clues????
