Re: [Mesa-dev] swrast gallium provider doesn't work on Solaris SPARC (Mesa 20 with LLVM 10)
Oh I missed that sparc is big endian. Still not sure where the llvm IR would differ but indeed some different unpacking somewhere could explain things. (And I'd guess we'd get issues reported for other big endian archs soon enough too...)

[Mesa-dev] [ANNOUNCE] mesa 20.1.0-rc4
Hi all, I'd like to announce the fourth release candidate for the 20.1 branch, Mesa 20.1.0-rc4. As always, please test it and report any issues you may find to https://gitlab.freedesktop.org/mesa/mesa/issues/new And to help us track issues and merge requests relevant to this branch, please add them to the 20.1.0 release milestone: https://gitlab.freedesktop.org/mesa/mesa/milestones/14 There are still several open issues that we need to close before the final 20.1.0 release, which is currently planned for the 27th, ie. next week.
