Abstract

A heuristic prediction method of generating profile information for compilers in a computer system that associates profile information to attribute-vectors of a source code derived from observation points in the code during compilation. The prediction method of the present invention enables the compiler to predict the code run-time behavior even before the code has been compiled, therefore providing an ideal way to maintain profile information. In addition to heuristically predicting code run-time behavior, the compiler of the present invention includes features that allow the compiler user to generate profile information of code being compiled using conventional profile generation methods.
