From b516e68afb548894eff6b1f375c01f6dfafb6aed Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 10 Jun 2015 19:59:20 -0400 Subject: [PATCH] draw: updates to support SVIEW decls To allow for shaders which use SVIEW decls for TEX* instructions, we need to preserve the constraint that the shader either has no SVIEW's or it has one matching SVIEW for each SAMP.
