> Possibly, does blender work now (or at least does it no longer crash)?
Yes, it doesn't crash anymore, thanks!
There are still other bugs that prevent it from running, and as I understand
most renderer features are disabled with default flags/defines under Mesa...
>From https://developer.blender.org/T41912 - "Note though: Building without SVM
gives you only very basic clay like rendering, not really usable."
The first bug is about libclc - it incorrectly references fabsf() in R600
bytecode files, while it should probably use llvm.fabs.f32()... Where to report
it?
Second, it seems Blender developers are using half-precision floats
(vstore_half4 function)... it's used in only one place and I don't know if its
usage is really critical, but it of course prevents the kernel from
compiling... I've reported it here https://developer.blender.org/T42813
