A cost and a benefit are calculated for relocating the at least one of the plurality of instructions to the at least one location, the cost and the benefit based on the path profiling information. The at least one of the plurality of instructions is moved to the at least one location when the benefit exceeds the cost, and one of predication and speculation is performed on the one of the plurality of instructions.
