Hmmm, I haven't dug deep into this, but it seems PRE is creating a NAN, even
though -ffinite-math-only. Is that right?
Created phi prephitmp_29 = PHI <_28(10), Nan(9)>
This causes us to return TRUE for this, even though we could have a NAN.
static inline bool
finite_operands_p (const frange &op1, const frange &op2)
{
return flag_finite_math_only || (!op1.maybe_isnan () && !op2.maybe_isnan ());
}
finite_operands_p() must be adjusted for the case where there is a NAN in the
source...but still.. is PRE supposed to be adding NANs?
