From 884df9ef834d6b77226d0dfd778c5317365a2394 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 24 Apr 2015 10:47:03 +1000 Subject: [PATCH] glsl/ir: allow ir_call to handle subroutine calling This adds a ir_variable which contains the subroutine uniform and an array rvalue for the deref of that uniform, these are stored in the ir_call and lowered later.
