What AI says about GLSL Optimizer

GLSL Optimizer is a C++ library that applies GPU-independent optimizations (such as function inlining, dead code removal, constant folding, and copy propagation) to GLSL shaders and outputs optimized GLSL or Metal source code. It was originally developed for Unity's shader compilation pipeline, and it incorporates Mesa 3D's GLSL compiler with added precision handling for GLES types.
