From: José Fonseca Date: Fri, 14 Mar 2014 17:01:05 +0000 (+0000) Subject: llvmpipe: Simplify vertex and geometry shaders. X-Git-Tag: upstream/10.3~2934 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b995a010e688bc4d4557e973e5e28091c378e881;p=platform%2Fupstream%2Fmesa.git llvmpipe: Simplify vertex and geometry shaders. Eliminate lp_vertex_shader, as it added nothing over draw_vertex_shader. Simplify lp_geometry_shader, as most of the incoming state is unneeded. (We could also just use draw_geometry_shader if we were willing to peek inside the structure.)
