Convert DXBC to DXIL (DirectX Bytecode to DirectX Intermediate Language)

Question

Microsoft's open source DirectX Shader Compiler describes the format of a new intermediate language (IL) for HLSL shaders called DXIL.

The documentation makes reference to a converter from the previous HLSL IL, called DXBC, to the new DXIL: https://github.com/Microsoft/DirectXShaderCompiler/blob/master/docs/DXIL.rst.

However, I am unable to find the referenced dxbc2dxil tool, or any other way to convert DXBC to DXIL. I have tried passing DXBC files to the various tools in the DirectX Shader Compiler project, but none have accepted plain DXBC as input.

Is there currently a way to obtain DXIL from old DXBC?

My understanding of this documentation is that Microsoft will take charge of only providing DXIR to the vendor's drivers in the future. The DXBC2DXIL is a Microsoft internal only module.

To my knowledge, nothing in the DirectX Shader Compiler repository has the capability to translate a DXBC IL to a DXIL.

Thanks for your answer @galop1n. Having that tool publicly available would be nice, so hopefully Microsoft will release some version of it eventually. – Kerry Seitz Aug 08 '17 at 23:17
Confirmed that dxbc2dxil is not currently public: https://twitter.com/mlrdev/status/895140130553384962 – Kerry Seitz Aug 11 '17 at 18:12

See this project for a working hack: https://github.com/Nukem9/Dxbc2Dxil

They use "dxilconv.dll" from win10 to create an instance of the undocumented DXBC->DXIL converter.
