From: Kenneth Graunke Date: Wed, 28 May 2014 06:50:23 +0000 (-0700) Subject: i965/clip: Use the new brw_last_inst macro instead of temporaries. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0bfac24caf89a163d8149e69b9eaa7ae5c71d550;p=mesa.git i965/clip: Use the new brw_last_inst macro instead of temporaries. It wasn't too bad before, but the macro is going to be nicer once I start modifying a lot more instructions in this pattern.
