"These functions return zero if neither argument is NaN, and a and b are equal." Note that due to some kind of historical accident, __eqsf2 and __nesf2 are defined to have the same return value.
pub fn __eqsf2(a: f32, b: f32) callconv(.c) i32
pub fn __eqsf2(a: f32, b: f32) callconv(.c) i32 {
return __cmpsf2(a, b);
}
