From e2707c8765b15b7ac666067160307c7f9d2d8b4d Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Tue, 20 Oct 2015 18:31:02 -0700 Subject: [PATCH] i965/fs: Emit a single ADD instruction for SET_SAMPLE_ID on Gen8+. Gen8+ lifted the register region restriction that an instruction whose destination spans two registers must have sources that also span two registers.
