graphical glitch

unigine-tropics and unigine-sanctuary don't runs. Required extension GL_EXT_framebuffer_multisample is not supported.

ArchLinux x86; kernel 3.10; mesa - git; xf86-video-ati - git; llvm - 3.3

Radeon HD 7950

OpenGL renderer string: Gallium 0.4 on AMD TAHITI
OpenGL version string: 2.1 Mesa 9.2.0-devel (git-796b73d)
OpenGL shading language version string: 1.30

If run MESA_EXTENSION_OVERRIDE="GL_EXT_framebuffer_multisample" unigine-tropics, test runs but have graphical glitch.
Comment 1 Michel Dänzer 2013-07-16 10:28:30 UTC 
Current st/mesa only advertises this extension if the driver actually supports multisampling.
Comment 2 Laurent carlier 2013-08-17 15:00:33 UTC 
Should be fixed since 21d9a1b5ef51ce449e9a82641d0d605c5448b41c
(You need at least LLVM-3.4svn)
Comment 3 Vladimir Usikov 2013-08-17 16:40:14 UTC 
On last llvm-svn and mesa git, glxgears show extension GL_EXT_framebuffer_multisample. But unigine-tropics show black screen and have error in console:

unigine-sanctuary just crash with single error:

LLVM ERROR: ran out of registers during register allocation

Do i mast create 2 bug report for each case?

Yes, please.
