glxinfo

On my RadeonHD 7950, some games will get as far as the menu but by using
glxgears it segfaults on start with the message 'LLVM triggered Diagnostic
Handler: unsupported call to function llvm.AMDGPU.rsq in main'. Some games will
crash xorg, some will just segfault. SuperTuxKart has also been tested and the
game does not crash until actual 3D elements are drawn, as with Team Fortress
2.

Distro is Arch Linux
Environment is XFCE4
Kernel Version: 3.15.0-1-mainline
glxinfo is dumped to file
LLVM Version: 3.5.0svn (211341-1)

Thanks for checking.
