3-valued logic functions
// 3-valued logic functions based on the encoding described in
// "Boolean Analysis of MOS Circuits"
// http://www.cs.cmu.edu/~bryant/pubdir/tcad87b.pdf
//
// Each of the 3 states, 0, 1 and X is encoded using 2 bits
// 0 => 01
// 1 => 10
// X => 11
//
// with 00 indicating an invalid state (used for uninitialized signals).

bgfx shader custom MSBuild rule for VS2013

Installation

  1. Download all 3 files and place them at the same folder as your VS solution
  2. Build shaderc and move the executable to the same folder. If you get the original executable from the build directory, remember to rename it to shaderc.exe instead of shadercRelease.exe
  3. Open your solution into VS, right click on the project and select Build Dependencies > Build Customizations...
  4. Click Find existing... and select the bgfxshader.targets file you just created
  5. Add .sc files to your project and they should be treated as bgfx shaders

To verify that the new target works correctly you can right click on an .sc file and select Properties. Item Type property should read "bgfx Shader"
