Created attachment 66294 [details] The desktop with compiz. Today I decided to give the llvm shader compiler a try, so I compiled mesa (from git) with it enabled. The result was a completely broken desktop. With the help of a 2d desktop environment I was able to capture some screenshots/videos from Minecraft (see attachments). No information in dmesg and/or Xorg.0.log (I attach them anyway).

Created attachment 66297 [details] Xorg.0.log
As the video is to big for an attachment here's a link: https://vimeo.com/48479243 It shows Minecraft in-game.
The llvm backend hasn't been tested much on Cayman, so probably some of the Cayman specific features aren't working correctly. Could you set the environment variable R600_DUMP_SHADERS=1 and then post the debug output from compiz and minecraft?

It seems alu instruction 0x86 RECIP_IEEE is emitted in a single slot, though IIRC it should be at least on three slots x-z.
