fa86fc564aea4e40c89f6fc889e6a5bf817634b3 is the first bad commit commit fa86fc564aea4e40c89f6fc889e6a5bf817634b3 Author: Jerome Glisse <jglisse@redhat.com> Date: Fri Dec 3 20:47:02 2010 -0500 r600g: build fetch shader from vertex elements Vertex elements change are less frequent than draw call, those to avoid rebuilding fetch shader to often build the fetch shader along vertex elements. This also allow to move vertex buffer setup out of draw path and make update to it less frequent. Shader update can still be improved to only update SPI regs (based on some rasterizer state like flat shading or point sprite ...).
