Now that libclc uses spirv-llvm-translator and we package weekly LLVM 16 snapshots, is there any chance to get snapshots of spirv-llvm-translator (with empty KEYWORDS) that would work with the respective LLVM versions?

Comment 1 Jan Henke 2022-11-19 10:59:25 UTC

I took this package mainly because it is a dependency of intel-compute-runtime and was maintainer-wanted at that time. So far it mainly required a bump once for every LLVM release.

I currently do not see pushing a weekly snapshot myself, especially via proxy-maint.

So I think we have the following options:
1. -9999 live ebuild, so no explicit snapshots, but ability to build upstream git.
2. Informal agreement that you, or someone else maintaining libclc, uploads snapshot-ebuild on a by demand basis, while the stable ebuilds are still maintained by Conikost and myself.
3. You take over this package if your package has more specific requirements than intel-compute-runtime.

I have no preference towards one particular of the options, so just pick which one suits your needs best. intel-compute-runtime just needs a version matching the used LLVM version, but usually lacks behind LLVM stabilisation anyway. Therefore I assume you need new versions way before they have to be stabilized for my package.

Are you by any chance aware if upstream is adding support for new LLVM versions prior to their release?

Comment 3 Jan Henke 2022-11-19 11:21:18 UTC

Sorry, I do not actively follow upstream. My use case is limited to adding a new version if intel-compute-runtime requires one (or if someone requests a bump via a bug).

Looking through upstream repo, i looks like, that could be some LLVM16 support. Upstream CMakeFiles in Git require LLVM 16.

I wouldn't bet, that support is fully done. Someone would need to test it. Looking from our primary consumer, intel-graphics-compiler, I don't see any way to test, as intel-graphics-compiler currently does not support LLVM15 and LLVM16.
