From 3412069e23b7fa5656262f3dd1aa86f66980594d Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 27 Apr 2011 21:50:20 -0700 Subject: i965: Don't compute brw->wm.input_size_masks when it's unused. It's only used in the old fragment program path, to avoid projection when w is always 1. We do want to do this in the new path pre-gen6 too, but we'll probably do it through the ir.
