Execution tests for the 'max' builtin function
S is abstract-int, i32, or u32
T is S or vecN<S>
@const fn max(e1: T ,e2: T) -> T
Returns e2 if e1 is less than e2, and e1 otherwise. Component-wise when T is a vector.
S is abstract-float, f32, f16
T is vecN<S>
@const fn max(e1: T ,e2: T) -> T
Returns e2 if e1 is less than e2, and e1 otherwise.
If one operand is a NaN, the other is returned.
If both operands are NaNs, a NaN is returned.
Component-wise when T is a vector.
