It did, I fixed it. Thanks for the insight.

The fp-int-convert-long-double test does this:
static volatile signed long long ivin, ivout;
static volatile long double fv1, fv2;
ivin = ((signed long long) (((unsigned long long) ~(unsigned long long) 0) >>
1));
fv1 = ((signed long long) (((unsigned long long) ~(unsigned long long) 0)
