Example of an idiotic benchmark:
int
main()
{
long long i;
double q;
for (i=0; i<10000000; i++) {
q = sqrt(i);
}
}
Under gcc 3.3.5 (Debian Sarge) this pile of drek executes in 1.4-1.8
seconds (depending on -O level). Under icc 9.0 it executes between in
3.4 seconds for -O0 and -O1, and in 0.015 seconds for -O2.
And don't tell me this is not a valid benchmark. I know. This is as
artificial as I can get without using a wooden leg.
