Shader Debugging

Shader level debugging can be enabled and used through Pix

Simply add the kGfxCreateContextFlag_EnableShaderDebugging upon creating the gfx context (This is done automatically in Debug builds of the default applications)

contextGFX = gfxCreateContext(
    window, kGfxCreateContextFlag_EnableStablePowerState
#if _DEBUG
    | kGfxCreateContextFlag_EnableDebugLayer | kGfxCreateContextFlag_EnableShaderDebugging
#endif
    );

Then, in Pix, go to Home -> Settings -> Symbol / PDB Options and add the shader_pdb directory to the list of PDB search paths:

Finally, perform a Pix capture as normal and start the analysis:

Pick the pass that you want to debug in the Events view:

And go to the Debug tab to start debugging:

You should be able to insert breakpoints, step over/in/out, inspect the locals, etc.
