Checkout-specific technical note

[SPIR-V] generated SPIR-V is invalid: Result type (OpTypeStruct) does not match the type that results from indexing into the composite (OpTypeStruct).

This note maps the reported failure in microsoft/DirectXShaderCompiler to the artifact prepared for benchmark revision 811bf1f1993e620b1292c52f41aeb43f2529855f.
