ABSTRACT:
A compiler and method of compiling provide partial redundant copy elimination by eliminating copy statements having at least one eligible reachable use and at least one ineligible reachable use. To eliminate such statements, the used operand of each eligible use is replaced with the used operand in the copy statement, and the copy statement is duplicated prior to each ineligible use.
