From 798c094e6266bf53b332f332e82a90c338c49915 Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Sat, 20 Dec 2014 18:02:29 -0800 Subject: [PATCH] i965/vec4: Do separate copy followed by constant propagation after opt_vector_float(). total instructions in shared programs: 5877012 -> 5876617 (-0.01%) instructions in affected programs: 33140 -> 32745 (-1.19%) From before the commit that allows VF constant propagation (which hurt some programs) to here, the results are: total instructions in shared programs: 5877951 -> 5876617 (-0.02%) instructions in affected programs: 123444 -> 122110 (-1.08%) with no programs hurt.
