Build failure in mesa 07ae697... (r600g: merge the TXQ and BUFFER constant buffers, committer Dave Airlie)
make ends with the following error:

Comment 1 Alexandre Demers 2014-11-27 03:06:54 UTC
Dave, compared to your original patch (http://patchwork.freedesktop.org/patch/37363/), it seems the changes in src/gallium/drivers/r600/r600_llvm.c are missing in the commit.
Comment 2 Dave Airlie 2014-11-27 03:18:35 UTC
oops pushing fix now.
Comment 3 Jos van Wolput 2014-11-27 04:03:49 UTC
(In reply to Dave Airlie from comment #2)
> oops pushing fix now.
Dave,
it still doesn't build after your fix!
Now getting the following error (after make clean):

this time for sure,

I don't advice using the llvm compiler backend for r600 btw.
