  • Determining maximum number of live registers by recording relevant events of the execution of a computer program
    Patent number: 6609249
    Abstract: The present invention is a method and apparatus for compiler optimization that determines the maximum number of live computer registers, or pressure point. The present invention improves the productivity of a software developer by reducing compilation time of a computer program. More particularly, the overhead required during compilation to search information to determine the maximum number of live registers is reduced. The present invention records the relevant events related to the execution of a computer program, as opposed to a comprehensive history of the read instructions and write instructions. Also, the present invention maintains information about the maximum number of live registers for any partition related to the execution of a computer program. The present invention may bound the required system resources required to determine the maximum number of live registers to the number of registers associated with the number of partitions.
