557a71c50631a232528f654fa8b8e4add0e565d2 is the first bad commit commit 557a71c50631a232528f654fa8b8e4add0e565d2 Author: Dave Airlie <airlied@redhat.com> Date: Thu Sep 2 09:45:37 2010 +1000 mesa/st: remove check for buffer/elements = 0 shown by the glsl-vs-point-size failing on r600g. the test passes on softpipe and I get a full piglit test run completing on r600g. :040000 040000 9356be064454237c04de83968ab2376287bca610 757653a77f4742333d2c7ed51d4eb51b72e604e7 M src bisect run success *** Bug 30165 has been marked as a duplicate of this bug. *** piglit glsl-vs-point-size crashes on softpipe with the same backtrace. It was a bug in the SSE code path. Fixed with Mesa commit 4b27c614cf4b06ad0c2a0414f60737f19eed021d. mesa: fd266ec62ca772a8551d2d7922d718d9d84bdf07 (master) mesa: 83917660f1323bd8a50e8ba6ed2ff33d36880371 (7.9) Verified fixed. vp-ignore-input and glsl-vs-point-size pass on softpipe. |
