The target type generated for `RWBuffer<int4>` does not have its `isSigned` field set to `1` and the resource is treated as unsigned. This probably applies for all typed buffers with integer vector element types.
```
RWBuffer<int4> Buf : register(u0);
[numthreads(4,1,1)]
void main() {
Buf[0].x = 42;
}
```
Clang:
```
%"class.hlsl::RWBuffer" = type { target("dx.TypedBuffer", <4 x i32>, 1, 0, 0) }
@Buf = internal global %"class.hlsl::RWBuffer" poison, align 4
