From: Eric Anholt Date: Thu, 3 Oct 2013 16:58:43 +0000 (-0700) Subject: i965: Move the common binding table offset code to brw_shader.cpp. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=705a90e30435490c2de84f4f6741cab335fa7608;p=mesa.git i965: Move the common binding table offset code to brw_shader.cpp. Now that both vec4 and fs are dynamically assigning offsets, a lot of the code is the same. v2: Avoid passing around the next offset through the class.
