Abstract
A loop detection method, system, and article of manufacture for determining whether a sequence of unit processes continuously executed among unit processes in a program is a loop by means of computational processing performed by a computer. The method includes: reading address information on the sequence of unit processes; comparing an address of a unit process as a loop starting point candidate with an address of a last unit process in the sequence of unit processes; reading call stack information on the sequence of unit processes; comparing a call stack upon execution of the unit process as the loop starting point candidate with a call stack upon execution of the last unit process; outputting a determination result indicating that the sequence of unit processes forms a loop if the respective comparison results of the addresses and the call stacks match with each other.
