How's this coming along?

Is it in a working state of is it still very much a prototype?

I would say it is still very much a prototype. Bytecode parsing works, but the HLSL output is not valid at this stage.

Would you be a little bit clearer on what is going on in the project right now? Specifically what it supports and your plans for it? Also what is the "OldHLSLDecompiler" stuff about? I was thinking about fixing some stuff but not really sure what you plan to do with that.

turn it to a continues status/update thread?

@olie304 I plan to support DX9 Shaders (SM2, SM3), DX10 Shaders (SM4, SM5), and potentially DX12 shaders (SM6). The goal being readable and correct HLSL.

I plan to throw out OldHLSLDecompiler completely. the current design in master is a two phase system:

1. Parse Bytecode into a Bytecode Container
2. Convert Bytecode Container to HLSL source .

I am in the process of replacing it with a 3 stage design and OldHLSLDecompiler will be removed once that is done.

1. Parse Bytecode into a Bytecode Container
2. Convert Bytecode into a intermediate representation
3. Convert intermediate representation to HLSL source.

The new IR phase would allow type reconstruction, instruction lifting, better sharing of DX9 and DX10 HLSL generation code and assuming SM6 is supported, revectorization and structured control flow reconstruction. I have pushed the IR changes to master, but the current state is not as advanced as OldHLSLDecompiler was, I am in the process of investigating how well the IR can support DX12 (SM6) shaders.
