Yes, this fixes the big regression and I also no longer see the original
regression.

native inst support for mesa

Sorry, I didn't notice that mesa didn't translate native instruction for r700.
You'll need this patch, as well as the previous one ; it should fix the big
regression. Can you confirm this ?

Ok, I always looked on mesa-dev for bugs, thank for pointing me this.

Does the "big" regression still occur with at least revision r178667 for llvm
and commit
http://cgit.freedesktop.org/mesa/mesa/commit/?id=159d9340662a70df3dcc9da1681f5b0a8e7650cf
for mesa ?

  drivers/gallium/r600 bugs get sent to the dri-devel list.

No, I don't receive mail from bugzilla until someone add me manually to the cc
list (dont know what to do to fix that though)

I'm aware of the regression with latest HEAD, I'm working on a fix.
r600g still adds CF_ALU on its own which break CF_CLAUSE address natively
encoded by llvm.

heaven regressed more with current heads

The recent changes to llvm and mesa have regressed heaven more.

Still OK with R600_LLVM=0, and other games are not affected.

OK, it is in llvm. Bisecting with mesa on head comes up with -

  I tried finding a working commit going back with mesa, but I get to a point
  where llvm renders nothing at all with anything using current llvm svn.
 
 There have been incompatible changes to the interface between r600g and the
 LLVM R600 backend, so you'd probably need a matching LLVM snapshot. The Git
 mirror at http://llvm.org/git/llvm.git might be helpful for this.

There have been incompatible changes to the interface between r600g and the
LLVM R600 backend, so you'd probably need a matching LLVM snapshot. The Git
mirror at http://llvm.org/git/llvm.git might be helpful for this.

 I tried finding a working commit going back with mesa, but I get to a point
 where llvm renders nothing at all with anything using current llvm svn.

There have been incompatible changes to the interface between r600g and the
LLVM R600 backend, so you'd probably need a matching LLVM snapshot. The Git
mirror at http://llvm.org/git/llvm.git might be helpful for this.
