From 7e86b2ddae32fc86fc684a0dcf32a87a0d795267 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 12 Oct 2016 00:00:28 +0200 Subject: [PATCH] draw: initialize shader inputs This should make the code more robust if a shader tries to use inputs which aren't defined by the vertex element layout (which usually shouldn't happen). No piglit change.
