I think this PR just needs to update the SPIRV-LLVM-Translator to the version matching clspv.

Yes but the second clspv/LLVM update may or may not fix the CMake/Ninja problem on windows. EDIT: looks like the required changes have not landed in the translator's main yet.

LLVM 23 has not been released yet, but LLVM main is already at 23. The translator is stuck as requiring 22 as long as official 23 LLVM packages are not released.

That's again a sign that we should consider having a clspv branch following LLVM releases to avoid such issues.

[rjodinchr]

We are making a llvm/release/22.x branch in clspv. I think that would be the one to use for clvk. And then update from release to release to avoid llvm's trunk. We can always backport commit in clspv's llvm/release/x.x branches if we really need to.
google/clspv#1558

[rjodinchr]

This is not going to work. We need the fix for the presubmit from #850

[kpet]

Thanks for pointing that out. I'll cherry pick it. I'm also struggling to build locally (facing issues with libclc now).

[rjodinchr]

The clspv pointed by this PR is too recent. Please reset it to google/clspv@a3d9d290.
#850 should have validated that point. Then we will see to update it to ToT.

That point should unlock what we need for the PR in clvk, and it will avoid bringing unstable stuff that we have in clspv at the moment (regarding libclc).
