           Summary: [r300g] LLVM support for software TLS implementation
                    doesn't work
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: drill87 at gmail.com

Hello. A month ago I started to use --enable-gallium-llvm while compiling mesa
git version and got a great performance increase - glxgears showed 800 fps vs
250 without LLVM.
  But in newer git versions (starting from the end of November or so) this
option stopped to help me - I've got 250 fps both with --enable-gallium-llvm
and without today.
  So is LLVM support (as I understood) for TLS implementation working in r300g?
Or the problem only on my side...

Kernel: 2.6.36 x86-64 (Archlinux 64)
