Abstract
In some embodiments, the invention includes a method of compiling instructions of a program. The method includes receiving instructions for code motion and controlling the code motion while interacting with block ordering. The code motion may be done as part of various activities including instruction scheduling, partial redundancy elimination, and loop invariant removal. The scheduling may involve making an assessment of the cost of scheduling an instruction that takes into account generation and/or elimination of branches due to resulting block order update and determining whether to make the code motion based on the cost. Instruction scheduling may involve regeneration of predicate expressions to invert conditional branches.
