...Sparc and RISCV. Due to the lack of a Dyld and the fact that SPIR-V is intermediate format, there is no point of a jit, Simple optimisations (CSE,DCE, some very simple inlining) would be nice to have, as would DebugInfo support. The code is available at my GitHub: SPIRV backend https://github.com/thewilsonator/llvm-target-spirv LLVM https://github.com/thewilsonator/llvm/tree/compute should you want to inspect/offer advice. I am very busy until about July, but I just want to put this out here to gather interest / feedback / contributors. Thanks, Nicholas Wilson -------------- next part -------------...

Hello, Since 2015 Khronos has switched to the new portable intermediate format SPIR-V, which has replaced the original SPIR. The advantage is that it offers higher portability across different toolchains. There was a talk about it at a Dev Meeting: http://llvm.org/devmtg/2017-03//2017/02/20/accepted-sessions.html#17 LLVM currently only supports SPIR format for OpenCL in Clang. Several Khronos

I think I need to write one anyway because I need to generate lots of tables other than the instruction table (there are no registers and therefore no register table), at least one

Hi, for a few months already I have been asking around for opinions on how people could best work together on Khronos' SPIR-V <-> LLVM-IR converter and some consensus seems to have formed. Most of the people I talked to favored having the converter become an external tool within the LLVM project, similar to libclc. I think that the LLVM project's processes, infrastructure and
