| Summary | r600g: 'invalid read' linking geometry shader |

Created attachment 93669 [details] gl-320-primitive-shading.trace I am happy that r600g gained OpenGL 3.3 support in Mesa, so I tested a few geometry shader samples. gl-320-primitive-shading either segfaults or prints error messages when run. According to valgrind there is an invalid read when linking the shader. I have reproduced the invalid read with glretrace too (see attachment). Kernel is 3.14.0-rc1 + merge of 7c4c62a04a2a80e3feb5d6c97aca1e413b11c790 from drm-fixes: $ uname -a Linux debian 3.14.0-rc1-00015-g7c4c62a #48 SMP PREEMPT Sat Feb 8 17:33:48 EET 2014 x86_64 GNU/Linux Mesa is from the 10.1 branch: $ glxinfo |grep OpenGL OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD RV730 OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.0-rc1 (git-1e6bba5) OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 10.1.0-rc1 (git-1e6bba5) OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: Hardware is a Radeon HD 4650: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
