==== LLVM usage ====
[[File:GlassyMesa3D.svg|thumb|GlassyMesa is an LLVM-based compiler stack for shaders written in [[OpenGL Shading Language|GLSL]]. For SSA see the article [[Static single assignment form]].]]
In addition, using the modular structure of Gallium3D, there is an effort underway to use the [[LLVM]] compiler suite and create a module to optimize [[shader]] code on the fly.<ref>{{cite web

The library represents each shader program using an extensible binary intermediate representation called Tungsten Graphics Shader Infrastructure (TGSI), which LLVM then translates into [[GLSL]] shaders optimized for target hardware.
