Abstract
The present invention relates to a mechanism for adaptive run time compilation of traces of program code to achieve efficiency in compilation and overall execution. The mechanism uses a combination of interpretation and compilation in executing byte code. The mechanism selects code segments for compilation based upon frequency of execution and ease of compilation. The inventive mechanism is able to compile small code segments, which can be a subset of a method or subroutine, and comprising only single path execution. The mechanism thereby achieves efficiency in compilation by having less total code as well as having only straight line, or single path execution, code to compile.
