From 5a4dc285002e1924dbc8c72d17481a3dbc4c0142 Mon Sep 17 00:00:00 2001 From: Bas Nieuwenhuizen Date: Mon, 22 Jan 2018 09:01:29 +0100 Subject: ac/nir: Use instance_rate_inputs per attribute, not per variable. This did the wrong thing if we had e.g. an array for which only some of the attributes use the instance index. Tripped up some new CTS tests.
