From 824e8084ed557061cd7a008b08da15897277d66e Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 10 Nov 2017 13:13:46 -0700 Subject: [PATCH] svga: issue debug warning for unsupported two-sided stencil state We only have a single stencil read mask and write mask. Issue a warning if different front/back values are used. The Piglit gl-2.0-two-sided-stencil test hits this.
