LLVM -> SPIR-V

Thought this thread was promising. If this ends up happening, it could pave a much easier path for us to eventually make OSL work on non-Cuda GPU platforms.

Count me in...gonna dust off that OSL clang front-end. There's a clang-based c++ interpreter at CERN that's pretty neat, someone focused on CUDA support is giving an update tomorrow. Maybe I can nerd out on OSL fragments running at the LHC drawing ray-traced or Vulkan tachyons (well lit of course) soon. >> Our next meeting will be on 04 March 2021 at 17:00 Geneva (CH) Time/8:00PST. >> We are happy to have Simeon Ehrig presenting his work on C++ and CUDA -- "Cling’s CUDA Backend: Interactive GPU development with CUDA C++".

Hey Larry,
I directed Sean Baxter to the mailing list awhile back about his project Circle-lang as another way to approach this, emitting SPIR-V directly from C++ code here: https://lists.aswf.io/g/osl-dev/message/4399?p=,,,20,0,0,0::relevance,,sean,20,2,0,77939956 But I guess if Intel are donating an official SPIR-V backend that supports Vulkan-style and not just OpenCL, then that's great too!
