From e1a518e2b1490ff4afe2efc69aa64e193bfb1324 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 3 Oct 2012 16:15:07 -0700 Subject: i965/vs: Fix the mlen of scratch read/write messages. These messages always have m0 = g0 and m1 = offset, and write has m2 = data. Avoids regression in opt_compute_to_mrf() with a change to scratch writes to set up the data as an MRF write in the IR.
