--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm, this might be a bug in mpfr though. GCC uses MPFR to do constant folding.
Without constant folding libm produces:
1.4142135623730950488
That is:
```
#include <stdio.h>
#include <math.h>
int main(void) { volatile long double a = 2.0L; printf("%.20Lg \n",sqrtl(a)); }
```
