CrossGL/crosstl

CrossTL translates GPU shaders and compute kernels between languages. Every translation goes through CrossGL, a small intermediate language: a frontend imports GLSL, HLSL, Metal or another source language into CrossGL, and a code generator writes CrossGL out as GLSL, HLSL, Metal, SPIR-V, WGSL or another target. You can also write CrossGL directly and generate every target from one source file. CI measures this chart on every push to main and nightly. Every feature in a pinned upstream feature list gets a generated probe, CrossTL translates it, and the language's reference compiler or validator…
