ABSTRACT:
A method and mechanism for producing and executing self-steering program code. A method comprises analyzing program code and identifying portions which may be amenable to optimization. Having identified such a portion of code, at least one optimized version of the identified code is added to the program code. Additionally, a selection mechanism is added to the program code which is configured to select between two or more versions of the portion of code during runtime. The modified program code is then compiled with the added optimized version and the selection mechanism. During execution, monitoring of behavior of the code may be enabled or disabled. Based upon such monitored behavior, a different version of the code may be selected for execution. Various optimized versions may be selected for execution in a manner which takes advantage of the current behavior of the program.
