From cfff74629765d1d06313705f5ca80138c2182ef0 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Thu, 19 May 2016 10:25:47 -0700 Subject: mesa: Track the additional data in gl_shader_variable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The interface type, interpolation mode, precision, the type of the outermost structure, and whether or not the variable has an explicit location will be used for SSO validation on OpenGL ES.
