Dehao Chen 1ae1089dec Increases full-unroll threshold. ... Summary: The default threshold for fully unroll is too conservative. This patch doubles the full-unroll threshold This change will affect the following speccpu2006 benchmarks (performance numbers were collected from Intel Sandybridge): Performance: 403 0.11% 433 0.51% 445 0.48% 447 3.50% 453 1.49% 464 0.75% Code size: 403 0.56% 433 0.96% 445 2.16% 447 2.96% 453 0.94% 464 8.02% The compiler time overhead is similar with code size.
