Bug 263564 – [WGSL] texture_external as a global generates incorrect indices

• Status: RESOLVED
• Resolution: FIXED
• Component: WebGPU

[Mike Wyrzykowski]

Given the following WGSL globals:

@group(0) @binding(0) var inputTexture0: texture_external;
@group(0) @binding(1) var <uniform> kernel_offsets: array<vec4f, 9>;
@group(0) @binding(2) var <uniform> kernels: array<mat4x4f, 9>;
@group(0) @binding(3) var <uniform> bias: vec4f;


They appear to generate this AB:

struct __ArgumentBufferT_0 {
    texture2d<float> __global0_FirstPlane;
    texture2d<float> __global0_SecondPlane;
    float3x2 __global0_UVRemapMatrix;
    float4x3 __global0_ColorSpaceConversionMatrix;
    const constant array<vec<float, 4>, 9>& global1 [[id(1)]];
    const constant array<matrix<float, 4, 4>, 9>& global2 [[id(2)]];
    const constant vec<float, 4>& global3 [[id(3)]];
};

but [[id(1)]] should be [[id(4)]]
