From 54216173252bdaffd12c1bbbaba85e8131396cff Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Thu, 8 May 2014 13:29:20 +0200 Subject: [PATCH] i965: Avoid redundant call to brw_merge_inputs() in brw_try_draw_prims() We always call brw_merge_inputs() right before looping over the primitives but this can be called inside the loop for each primitive too. In the case we do it for the first primitive the call is redundant and can be skipped.
