Actualy, you can.

Archlinux uses llvm-amdgpu-snapshot which is Tom Stellard's snapshot.

In 9.1-devel, --with-llvm-shared-libs is turned on by default if you use 
--enable-opencl.

On the other side, LLVM contains a shared library, enabled by 
--enable-shared, called libLLVM-<version>.so (ie libLLVM-3.2.so) located 
in llvm libdir (/usr/lib/llvm in Archlinux) which contains ALL of static 
libraries linked into ONE SHARED library. On the other hand, you can use 
CMake and build all of static libraries as shared. The first mentioned 
works for me very well. I am not sure what's the condition of that in 
Mesa 9.0 world. But 9.1 should be out in no time, so it shouldn't matter.

Note, this is not from Archlinux. I use custom built system with custom 
built packages

$ du -sh /usr/lib/dri/r600_dri.so
5.7M    /usr/lib/dri/r600_dri.so
$ du -sh /usr/lib/gallium-pipe/pipe_r600.so
2.4M    /usr/lib/gallium-pipe/pipe_r600.so (no 
/usr/lib/gbm/pipe_whatever.so anymore, since pipes are shared by gbm and 
opencl)

Compared to 20MB Archlinux ones.
