  • System and method for automatically and selectively promoting object variables to method fields and variables in a digital computer system
    Patent number: 6308315
    Abstract: A code generating system generates, from code in a program, native code that is executable by a computer system. The computer system includes a memory subsystem including a heap in which objects are stored and a stack in which method variables are stored. The code generating system may be included in a just-in-time compiler used to generate native code that is executable by a computer system, from a program in Java Byte Code form, and specifically determines, in response to Java Byte Code representative of an operator for enabling instantiation of a new object, whether the object to be instantiated contains a variable to be used in processing of the received program code portion which can be promoted to a method variable, and, if so, generates native code to enable said variable to be instantiated on the stack.
