your pent_time.c code doesn't work for CPUs below 100MHz
(I'm using a Pentium OverDrive PODP83 (83 MHz)).
first
if (neax < 100000000 || neax > 1000000000) {
always is true because of `neax < 100000000', so I changed that to
if (neax < 10000000 || neax > 1000000000) {
(removed one zero) which then causes a floating point exception in
the following divl instruction:
neax = 0;
nedx = 10000000;
__asm__("divl %2"
:"=a" (neax), "=d" (nedx)
:"r" (cycles_per_second),
"0" (neax), "1" (nedx));
I don't know what's the best way to avoid that limitation:(
