file-format

Is the format of compiled pixel and vertex shader object files as produced by fxc.exe documented anywhere either officially or unofficially?

I'd like to be able to read the constant name to register assignments from the shader files. I know that the effects framework in D3DX can do this, but I need to avoid using D3DX as it may not be installed on user's machines and I don't need it for anything else so I want to avoid them having to run the directx update.

If the effects framework can do it, then so can I if I can find out the file format but I can' seem to find it documented anywhere.

As far as I know, certain mathematical functions like FFTs and perlin noise, etc. can be much faster when done on the GPU as a pixel shader.
