Abstract
An optimizing compiler has a function of determining whether the result of a statement to be executed precedent to a conditional branch statement is not referred to by one destination of the conditional branch statement. If the conditional branch statement is not influenced by the execution result of the precedent statement, the conditional branch statement is shifted in front of the precedent statement, to suppress the execution of the unnecessary statement. Therefore, the optimizing compiler shifts/copies conditional branch statements, to shorten the execution time of an object program.
