Summary|quadmath fminq/fmaxq with |fmin/fmax with
|signaling_NaN not work |signaling_NaN not work
--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
With `-fsignaling-nans` added, then we get the :
inf
inf
nan
nan
so ...
Even using float instead also cause the same output:
```
#include <type_traits>
#include <iostream>
#include <stdfloat>
#include <limits>
#include <cmath>
int main()
{
{
using T = float;
using L = std::numeric_limits<T>;
const T
a = L::infinity(),
b = L::quiet_NaN(),
c = L::signaling_NaN();
std::cout << "float\n";
std::cout << std::fmin(a, b) << std::endl;
std::cout << std::fmax(a, b) << std::endl;
std::cout << std::fmin(a, c) << std::endl;
std::cout << std::fmax(a, c) << std::endl;
}
}
```
So Looks like we convert sNaN to qNan if `-fsignaling-nans` is not supplied ...
