A 'fake' WebGPU implementation to test CPU WGSL implementations.
where naga fails:
- declaring variables that shadow predeclared types (is now allowed by wgsl)
webgpu:shader,validation,parse,shadow_builtins:*
- declaring variables with reserved names (is not allowed by wgsl)
- shadowing errors
var read : i32; var<storage, read> a: i32;=>webgpu:shader,validation,parse,shadow_builtins:shadow_hides_access_modelet atomicLoad = 4; _ = atomicLoad(&a);=>webgpu:shader,validation,parse,shadow_builtins:shadow_hides_builtin_atomic
textureBarrier()not implemented?webgpu:shader,validation,parse,shadow_builtins:shadow_hides_builtin_barriers
textureGather()only acceptsvecN<f32>coordswebgpu:shader,validation,parse,shadow_builtins:shadow_hides_builtin_texture- seems to be a regression in v22 => v23
- overall, it seems that naga does not perform any implicit conversions for builtin function calls.
