Bug 269114 – [WebGPU] Crash in Constraints.cpp:199 concretize

• Component: WebGPU
• Status: RESOLVED FIXED

[Mike Wyrzykowski]

Running https://gpuweb.github.io/cts/standalone/?q=webgpu:shader,validation,expression,call,builtin,bitcast:bad_type_nonconstructible:var=%22t%22;direction=%22from%22

crashes on a release assert because texture_depth_2d can not be bitcast:

    @group(0) @binding(0) var s: sampler;
    @group(0) @binding(1) var t: texture_depth_2d;
    @group(0) @binding(2) var<storage> b: array<i32>;
    var<private> v: i32;
    @compute @workgroup_size(1)
    fn main() {
      let p = &v;
      let x = bitcast<i32>(t);
    }
    

instead of release assert, we could probably return an error here since the wgsl is not valid
