Subject: r600g: add index_bias to index buffer bounds
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=44afac04eaac08eb49938001a65363bef6bd3d3b;p=mesa.git

r600g: add index_bias to index buffer bounds

This fixes ARB_draw_elements_base_vertex with max_index != ~0.

NOTE: This is a candidate for the 7.11 branch.
