Hello,
Attached is a patch to fix failures for mesa-opencl and mesa-opencl-icd building with the update to 21.1.6 for Mesa. This is from upstream, a change in meson.build that removed LLVM targets (for CMake users it seems) but then breaks compilation for us on a shared library LLVM build.
https://gitlab.freedesktop.org/mesa/mesa/-/issues/4443
https://gitlab.freedesktop.org/mesa/mesa/-/issues/4302
And the commit that changed it: https://gitlab.freedesktop.org/mesa/mesa/-/commit/80817b6e344258ac9b955f824ebf9019a0fc1610
The patch restores 'all-targets' to llvm_modules and successfully builds. Apologies about the long line and I'm still guessing at some of the scheme patching code. Since Mesa takes a while to build I didn't want to go through many iterations to get the code cleaner. Please feel free to make it better, and I would think mesa-opencl-icu should be able to inherit the patch from mesa-opencl, but I didn't try to do that.
Thanks,
John

I feel this is easier to follow when expressed as a good old patch, so I
took the liberty to do that and pushed it as
1685128e6e1147049feddee617a616ce7f3592c0.
Let me know if anything’s amiss.
Thanks!
Ludo’.

Looks good to me, thanks! I'll check in on Cuirass later to confirm the 2 mesa-opencl packages built, and report back if something has gone wrong.
Slowly but surely to getting core-updates-frozen done...
