From 3d466f3e9f76c91083f0cfbb8a76148bdb0d52a3 Mon Sep 17 00:00:00 2001 From: Constantine Charlamov Date: Sat, 24 Jun 2017 17:06:48 +0300 Subject: [PATCH] r600g: take into account offset to system inputs at tgsi_interp_egcm() Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=100785 v2: I was too much twiddling whether to initialize nsys_inputs at the beginning of shader initialization or for allocation of system values, and by the time I decided to go with the first one, I forgot to change it back.
