Bug #: 54230 Summary: r600-llvm-compiler completely broken at CAYMAN Classification: Unclassified Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: v10lator@myway.de
Created attachment 66294 --> https://bugs.freedesktop.org/attachment.cgi?id=66294 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).

--- Comment #5 from Tom Stellard tstellar@gmail.com 2012-08-30 13:13:28 UTC --- 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.
