From a1bfafc5a96012c14db9b0d28223ab54feae131c Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 7 Feb 2012 01:09:59 +0100 Subject: [PATCH] i965/fs: Add missing register allocation for 3rd sources. Our only instruction with a 3rd source so far was linterp, and that value was never register-allocated.
