From b8211ab3edb1bb9f414e8b4913609f48326e202e Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 21 Mar 2013 15:01:34 -0700 Subject: i965: Use the proper element of the prim array in brw_try_draw_prims. The VBO module actually calls us with an array of _mesa_prim objects. For example, it may break up a DrawArrays() call into multiple primitives when primitive restart is enabled. Previously, we treated prim like a pointer, always accessing element 0. This worked because all of the primitive objects in a single draw call have the same value for num_instances and basevertex. However, accessing an array as a pointer and using the wrong object's fields is misleading. For stylistic reasons alone, we should use the right object.
