From: Eric Anholt Date: Thu, 28 Apr 2011 04:50:20 +0000 (-0700) Subject: i965: Don't compute brw->wm.input_size_masks when it's unused. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3412069e23b7fa5656262f3dd1aa86f66980594d;p=mesa.git 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.
