From: Jason Ekstrand Date: Fri, 23 Mar 2018 05:11:23 +0000 (-0700) Subject: anv/pipeline: Do less deref instruction lowering X-Git-Tag: upstream/19.0.0~4350 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5cd7324a57a0c6dc2ecffef236e6efd778cb78aa;p=platform%2Fupstream%2Fmesa.git anv/pipeline: Do less deref instruction lowering This commit removes most of the deref instruction lowering. Instead of lowering early, we only lower textures and images and we only do so right before any of the anv image lowering passes.
