Author: Ilia Mirkin <imir...@alum.mit.edu> Date: Sat Feb 14 01:27:19 2015 -0500 st/mesa: treat resource-less xfb buffers as if they weren't there If a transform feedback buffer's size is 0, st_bufferobj_data doesn't end up creating a buffer for it. There's no point in trying to write to such a buffer, so just pretend as if it's not really there. This fixes arb_gpu_shader5-xfb-streams-without-invocations on nvc0.
