From 2ff7b121cad2892698ff1aa7690dd361ea2739a7 Mon Sep 17 00:00:00 2001 From: Olivier Galibert Date: Wed, 2 May 2012 23:11:41 +0200 Subject: [PATCH] glsl: Add an origin pointer in the function signature object. This points to the object with the function body, allowing us to map from a built-in prototype to the actual body with IR code to execute.
