From 1b9d1e13d8e14c348f6d6c8fab5f31e8768a1371 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Mon, 14 Oct 2019 02:40:11 -0400 Subject: [PATCH] nv50/ir: mark STORE destination inputs as used Observed an issue when looking at the code generatedy by the image-vertex-attrib-input-output piglit test. Even though the test itself worked fine (due to TIC 0 being used for the image), this needs to be fixed.
