Hon garbage rendering

Possibly affects other cards.

I bisected and the first bad commit is eb44c36df842af010269eda1be77c4aea8ebe736
r600g: add initial cube map array support (v2).

It either displays plain black or garbage textures.

I tested with Heroes of Newerth and Unigine heaven.

with unigine heaven I get black textures even before this, I'm not sure what I
could be going wrong running it here.

I'm testing on a caicos but I don't think barts will be too much different.

What do you mean about make clean ? between each git bisect I did a git clean
-fdx ant full rebuild.

Both are native x64 apps.

And I'm using LLVM compiler.

You'll need to use the old compiler for now.  Disable the llvm compiler or set
R600_LLVM=0.

Indeed, disabling the llvm compiler fixes the issue I'm facing.

Does it help if you set the following envvar with enabled llvm compiler?

MESA_EXTENSION_OVERRIDE="-GL_ARB_texture_cube_map_array"

No, it still fails to render correctly.

Is this still failing? I think Vincent fixed cube arrays with LLVM a while ago.
