Module: Mesa
Branch: master
Commit: 5aa8d8194c4975876276a9c57cdd672978a491ad
URL: http://cgit.freedesktop.org/mesa/mesa/commit/?id=5aa8d8194c4975876276a9c57cdd672978a491ad
Author: Ian Romanick <ian.d.romanick at intel.com>
Date: Wed May 14 19:47:28 2014 -0700
glsl: Make ir_variable::num_state_slots and ir_variable::state_slots private
Also move num_state_slots inside ir_variable_data for better packing.
The payoff for this will come in a few more patches.
No change Valgrind massif results for a trimmed apitrace of dota2.
