From 63684a9ae7a66f68df1f2c68cd9358e5622122a3 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 18 Nov 2010 17:54:07 -0800 Subject: glsl: Combine many instruction lowering passes into one. This should save on the overhead of tree-walking and provide a convenient place to add more instruction lowering in the future.
