Abstract
A code generating system generates, from code in a program, native code that is executable by a computer system. 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 generates, in response to Java Byte Code representative of a synchronization statement that synchronizes access by multiple threads of execution to at least one variable contained in the Java Byte code, one or more native code instructions that implements a wait-free synchronization methodology to synchronization access to the at least one variable. Since the instructions which implement the wait-free synchronization methodology do not require calls to the operating system, they can generally be processed more rapidly than other synchronization techniques which do require operating system calls.
