            Bug ID: 265343
           Summary: [WGSL] dot4U8Packed, dot4I8Packed do not appear to be
                    implemented
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

[WGSL] dot4U8Packed, dot4I8Packed do not appear to be implemented

I think something like (pseudo-code):

fn dot4U8Packed(e1: u32, e2: u32) -> u32

    auto v1 = as_type<uint4>(e1);
    auto v2 = as_type<uint4>(e2);
    return dot(v1, v2);

would work
