Shader Model 4 Assembly

  • Article

Shader Model 4 requires you to program shaders in HLSL. However, the shader compiler compiles the HLSL code into assembly that runs on the device. If you are using PIX for Windows to debug your shaders, you can choose to display shader code in either HLSL or assembly. This section lists the Shader Model 4 and Shader Model 4.1 assembly instructions that you may encounter when debugging a shader.
