--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So clang emits one or the other warning for the code but not both.
You can defect the warning in clang by doing:
```
extern void g( int);
void f(float a)
{
double b = a;
if (b == 0.1234)
g( 1);
}
```
LLVM actually opimizes away the comparison while GCC does not.
