From 7de1331662816d31fb9bed423b1e5372284a260e Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 18 Apr 2012 10:51:23 -0700 Subject: [PATCH] glsl: Add support for generating builtin code from GLSL instead of IR. This takes advantage of the builtin compiler to generate IR into a string, the same way we read GLSL for function prototypes for our profiles.
