From 4a121e1a90dc34677d9a68e8877dfe53f1e889a2 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Fri, 11 Sep 2015 17:01:23 -0400 Subject: [PATCH] glsl: add SYSTEM_VALUE_VERTEX_CNT Used internally in freedreno/ir3 to calc stream-out position. Seems like a generic enough way to implement stream-out (using str instrs), plus it avoids compiler warnings by sneaking in a non-enum value in switch statements.
