SPIR-V: Error message for `WaveMultiPrefix` functions is not easy to understand

[chaoticbob]

When compiling this shader:

StructuredBuffer<uint4> g_mask;

float4 main(uint4 input0 : ATTR0) : SV_Target {
    uint4 mask = g_mask[0];

    uint4 res1 = WaveMultiPrefixProduct(input0, mask);
    uint4 res2 = WaveMultiPrefixSum(input0, mask);
    uint4 res3 = WaveMultiPrefixBitAnd(input0, mask);
    uint4 res4 = WaveMultiPrefixBitOr(input0, mask);
    uint4 res5 = WaveMultiPrefixBitXor(input0, mask);
    return res1 + res2 + res3 + res4 + res5;
}

CMD

slangc.exe -target spirv -lang slang -D__spirv__ -emit-spirv-directly -profile ps_6_5 -entry main shader.hlsl

I get this result:

Guessing this is telling me that this function isn't supported by -target spirv?

Guessing this is telling me that this function isn't supported by -target spirv?

This is a correct interpretation of the error. WaveMultiPrefixProduct is the function causing the error in question due to only supporting hlsl and cuda.

This is related to:

1. 4347 to make the error easier to read

2. 4172 to more precisely describe the function causing the error

I suggest to close this issue as a duplicate to #4347.
