Bug 199086 – [WHLSL] Cannot use * qualifier/operator for buffer access and stores

• Status: RESOLVED
• Resolution: WONTFIX
• Component: WebGPU

[Justin Fan]

>These WHLSL codes fail in the checker:

[numthreads(1, 1, 1)]
compute void _compute_main(device int* result : register(u0))
{
    result[0] = 42;
}

OR

[numthreads(1, 1, 1)]
compute void _compute_main(device int[] result : register(u0))
{
    *result = 42;
}


>This code does not generate valid MSL output:

[numthreads(1, 1, 1)]
compute void _compute_main(device int* result : register(u0))
{
    *result = 42;
}


Metal compile error is:

program_source:12941:16: error: excess elements in scalar initializer
variable6663 = { variable6661.structureElement13, static_cast<uint32_t>(variable6662) };

WHLSL is no longer relevant.
