Hi

Kwin starts with a black screen if I use r600-llvm-compiler on my RS880

When I switched off the llvm parts and just ran glxgears using
r600-llvm-compiler the gears looked like they were layered wrongly and slightly
darker

I'm not sure when this regression appeared - I'm guessing within the last two
weeks - I mostly ssh into the box

I'm always running the latest llvm, clang, libdrm and mesa

I didn't see anything strange in my dmesg or .xsession-errors  or from the
glxgears text output

Could this be due to RS880 being singled out in llvm as a separate processor
variant?

ie r600g/llvm: Update radeon family mappings for LLVM backend or [PATCH 1/2]
R600: Add some new processor variants
