unhelpful diagnostic from naga regarding missing & #6983
Open
Description
wgpu version 24.0.0
While working on the reworked webgpu bindings for Deno, I attempted to run a test, which is a 1-1 copy of hello-compute but written in javascript.
So using this shader, I am getting this diagnostic:
Device::create_shader_module error:
Shader validation error:
┌─ :20:36
│
20 │ let array_length = arrayLength(input);
│ ^^^^^ naga::Expression [4]
error: GPUValidationError:
Shader validation error:
┌─ :20:36
│
20 │ let array_length = arrayLength(input);
│ ^^^^^ naga::Expression [4]
: Entry point doubleMe at Compute is invalid: Expression [4] is invalid: Loading of [3] can't be done
Apparently, thanks to @teoxoy the solution is to do arrayLength(&input). The diagnostic is not very helpful here.
Also unsure why this is happening, since the wgpu repo itself is using the shader as-is without this change, yet the example works fine.
