after updating mesa to latest git, i can not using opengl-apps anymore running glxgears give the following error message: EE r600_asm.c:121 r600_bytecode_get_num_operands - Need instruction operand number for 0xc testet with kernel 3.5.1 and 3.6.0-rc6 using xorg-server-1.12.2 and libdrm, mesa, xf86-video-ati from git removing xorg.conf gives the same error

Me too Also Unity on Ubuntu 12.04 displays black screen with only the mouse pointer. Switching to another virtual console or logging in Unity 2D works though. Radeon HD3450 (RV620) on Ubuntu 12.04 + OIBAF PPA
Can you bisect?
sorry, but which PATH environment variables i have to set? LD_LIBRARY_PATH="~/mesa/src/glx" glxgears does not work
Bisect is a git option to identify what commit caused a problem. Google for "git bisect".
yes ... i have google for it ;) so i should bisect mesa-git, right? * i have clone the mesa-git with git clone git://anongit.freedesktop.org/git/mesa/mesa * cd mesa * git checkout 9aa8bac9 (i think this was working "date 2012-09-19") * ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/usr/lib64 --disable-dependency-tracking --enable-dri --enable-glx --enable-texture-float --disable-debug --enable-egl --enable-gbm --enable-gles1 --enable-gles2 --enable-glx-tls --disable-osmesa --enable-asm --enable-shared-glapi --enable-xa --enable-xorg --with-dri-drivers= --with-gallium-drivers=,swrast,r600 --with-egl-platforms=x11,drm --enable-gallium-egl --enable-gallium-g3dvl --enable-gallium-llvm --disable-openvg --enable-r600-llvm-compiler --disable-vdpau --enable-xvmc * make * now i would like testing mesa, but how? running glxgears uses the system-libs from /usr/lib64. with EGIT_COMMIT="9aa8bac98b823e8783bc3a06a6e5b23fbf8d87fb" emerge mesa i got a working mesa.
my system is working and running with a mesa-build from 2012-09-19 how i could test the mesa-build in my home-dir?

You can set where to look for shared libraries by settings LD_LIBRARY_PATH=... and where to look for DRI drivers with LIBGL_DRIVERS_PATH=... E.g., LD_LIBRARY_PATH=<directory where libGL.so.1 lives> LIBGL_DRIVERS_PATH=<directory where r600_dri.so lives> glxgears will run glxgears with your new Mesa.
I can't reproduce this. Mesa master on RS880 is working fine here.
(In reply to comment #10) > I can't reproduce this. Mesa master on RS880 is working fine here. A quick search in the git log returned this: http://cgit.freedesktop.org/mesa/mesa/commit/?id=7b4aefd3c9c1b04832306b8114b3f2007318f087 Did you compile with --enable-r600-llvm-compiler ? It's enabled in my PPA.
i'm currently experiencing this with rs780 and darkplaces. I only get black screen, and logs are filled with this error. I have an llvm-enabled build of mesa. This is on current git @ fb40f88338b6af23faae03ced5906add8507db26

If you are using the llvm compiler setting the environment variable R600_LLVM=0 will cause the driver to fall back to the TGSI compiler and should fix the rendering errors. It would be helpful if someone could run one of the affected programs with the R600_DUMP_SHADES=1 environment variable set and post the output.

Sorry, typo above. The environment variable is R600_DUMP_SHADERS=1

in case it is important, i have set some environment variables belly@jelly ~/mesa $ env | grep R600 R600_STREAMOUT=1 R600_HYPERZ=1 R600_GLSL130=1 R600_TILING=1 R600_SURF=1 this was set for a few months to test something, i forgot to reset this
