From: Kenneth Graunke Date: Fri, 17 May 2013 18:46:16 +0000 (-0700) Subject: i965: Remove software geometry query code. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=647fc0c50bc9832c336b2b7e4329abec31df9dec;p=mesa.git i965: Remove software geometry query code. EXT_transform_feedback isn't yet supported on Gen4-5, so none of this query code is actually used. This also means we can remove some of the surrounding support code.
