Bug#697356:

[Fabio Pedretti]

There are some more informations here:
http://lists.freedesktop.org/archives/mesa-dev/2013-January/032205.html

Note that the llvm backend is optional and experimental for the r600 driver. I 
enabled it some time ago on my Ubuntu PPA ( https://launchpad.
net/~oibaf/+archive/graphics-drivers/ ) and many users experienced problems 
(see the phoronix thread).

About radeonsi, the llvm backend is required to build it, but xserver-xorg-
video-ati must also be compiled with glamor. glamor itself currently only works 
with xorg < 1.13:

So I see no hurry for this, better wait for llvm 3.3 which will include the 
proper and hopefully stabilized AMD backend and also a glamor which works with 
recent xorg.

Bug#697356: fix mesa ftbfs with llvm-3.2

[Timo Aaltonen]

Package: llvm-3.2
Version: 3.2-2
Severity: normal

Hi

  Mesa 9.0.1/master fails to build with the released llvm-3.2, since 
the radeonsi -driver needs changes to the AMDGPU target in llvm. Those 
can be found from


http://cgit.freedesktop.org/~tstellar/llvm/

I haven't actually tried building with that version, but got the link 
when asked mesa upstream about this.
