here are a few things that I would expect to fail that should be included in
this file
```hlsl
float fn(half2 p1, float2 p2, float p3) {...} // arg 2 needs to be a half2 type
float fn(float2 p1, half2 p2, float p3) {...} // arg 1 needs to be a half2 type
float fn(float2 p1, float2 p2, float p3) {...} // arg 1 & 2 needs to be a half2
type
float fn(float2 p1, float2 p2, double p3) {...} // arg 3 needs to be a float
```
