Abstract
A system and method are provided that in one aspect eliminate redundant array range checks by performing a versioning for a loop. In another aspect, a system and method optimize array range checks by performing data-flow analysis in reverse order of the program execution. Yet in another aspect, a system and method obtains information about array ranges already checked by performing data-flow analysis in program execution order and eliminate redundant array range checks from this information.
