From c3215ef204c0fdfc44230adbd423720169d44dcb Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Thu, 2 Jul 2015 00:13:36 -0400 Subject: nv50/ir: don't emit src2 in immediate form In the immediate form, src2 == dst, so it does not need to be emitted. Otherwise it overlaps with the immediate value's low bits.
