I think those patches are merged with llvm-trunk. Manually installation give me
hunks and fails.

I update/build/install llvm-trunk,ibclc-trunk mesa-trunk and now I still got
lock ups!???
( Using 3.11.rc5 with disabled dpm )

If you have clean patches, I can test them also.
Because this patches gives me 

/temp/llvm/lib/Target/R600/SIInstrInfo.td:39:1: error: def 'SIload_constant'
already defined

error at compile time...
Thanks
