From 2c5afe1fa98d01eb90577c8dbe785fc408f8608f Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 1 Apr 2016 20:52:33 -0700 Subject: [PATCH] glsl: Make vertex ID lowering declare gl_BaseVertex as hidden. If the GL_ARB_shader_draw_parameters extension is enabled, we'll already have a gl_BaseVertex variable. It will have var->how_declared set to ir_var_declared_implicitly, and will appear in the program resource list. If not, we make one for internal use. We don't want it to be listed in the program resource list, as the application won't be expecting it. Marking it hidden will properly exclude it.
