From 06de9f8ff15559dffddf26d1969d35e74fbf253f Mon Sep 17 00:00:00 2001 From: Chris Forbes Date: Sun, 13 Oct 2013 00:02:55 +1300 Subject: [PATCH] i965: Generalize coord+offset lowering pass for ir_txf ir_txf expects an ivec* coordinate, and may be larger than ivec2; shuffle things around so that this will work.
