SPIRV-LLVM-Translator

Nim too, as it can use Zig as a compiler. There's also https://github.com/treeform/shady to compile Nim to GLSL. Also, more generally, there's an LLVM-IR->SPIR-V compiler that you can use for any language that has an LLVM back end (Nim has nlvm, for example): https://github.com/KhronosGroup/SPIRV-LLVM-Translator That's not to say this project isn't cool, though. As usual with Rust projects, it's a bit breathy with hype (eg "sophisticated conditional compilation patterns" for cfg(feature)), but it seems well developed, focused, and most importantly, well documented. It also shows some positive signs of being dog-fooded, and the author(s) clearly intend to use it. Unifying GPU back ends is a noble goal, and I wish the author(s) luck.

FWIW, there already exists LLVM to SPIR-V compiler: https://github.com/KhronosGroup/SPIRV-LLVM-Translator Alas, this supports SPIR-V to 1.1.

I'm not dead yet. I've just had a bit of fun updating the SPIR-V backend to use https://github.com/KhronosGroup/SPIRV-LLVM-Translator instead of the old one which wasn't being updated. I'm in the process of adding clspv as a backend for Vulkan Compute shaders (in turn as a basis for targeting Intel's ispc compiler optimisations). Most of that fun involves bashing CMake around that head to try to get it to talk properly with pkg-config (I hate them both).
