dominator optimization: 17.89 ( 7%) usr 0.88 ( 4%) sys 21.48 ( 6%) wall
expand : 13.68 ( 5%) usr 0.81 ( 3%) sys 18.65 ( 6%) wall
CSE : 53.15 (20%) usr 0.59 ( 2%) sys 60.06 (18%) wall
CSE 2 : 36.92 (14%) usr 0.18 ( 1%) sys 41.34 (12%) wall
tree SSA other : 6.88 ( 3%) usr 5.10 (21%) sys 13.43 ( 4%) wall
tree PRE : 5.38 ( 2%) usr 0.41 ( 2%) sys 6.24 ( 2%) wall
PRE : 5.43 ( 2%) usr 0.58 ( 2%) sys 6.47 ( 2%) wall
