From a07d70c54bae60be0c549d2a6ece509ed29432f8 Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Tue, 8 Oct 2019 13:48:00 +0200 Subject: [PATCH] v3d: we always have at least one output segment MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If we program an output size of 0 the simulator asserts. This was not a problem until now because our VS would always have to emit fixed function outputs, however, now that it can be paired with a GS we can end up with a VS shader that no longer emits any outputs.
