ABSTRACT:
One embodiment of the present invention provides a system that facilitates optimizing computer program performance by using steered execution. The system operates by first receiving source code for a computer program, and then compiling a portion of this source code with a first set of optimizations to generate a first compiled portion. The system also compiles the same portion of the source code with a second set of optimizations to generate a second compiled portion. Remaining source code is compiled to generate a third compiled portion. Additionally, a rule is generated for selecting between the first compiled portion and the second compiled portion. Finally, the first compiled portion, the second compiled portion, the third compiled portion, and the rule are combined into an executable output file.
