From c2065ed687dd714240928827f620852e37f7dffc Mon Sep 17 00:00:00 2001 From: Nicolai Hähnle Date: Sun, 25 Jun 2017 18:13:39 +0200 Subject: st/glsl_to_nir: fix edgeflag passthrough MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We have to mark the additional shader input as used, otherwise it will be eliminated, and we have to setup its index correctly. This is a bit of a hack, but so is everything surrounding edgeflag passthrough.
