Abstract

A computer implemented method optimizes source code. A processor set receives a source code in a first version. The processor set compiles the source code in the first version to generate an intermediate representation for the source codes in the first version. The processor set compares the intermediate representation for the source code in the first version to a number of optimization paths. The processor set identifies a number of matches based on the comparisons. The processor set updates at least a portion of the source code in the first version to the second version based on the number of matches to generate the source code in the second version.

Dependent claims

A computer implemented method for optimizing source code, the computer implemented method comprising:

receiving, by a processor set, a source code in a first version;
compiling, by the processor set, the source code in the first version to generate an intermediate representation for the source code in the first version;
comparing, by the processor set, the intermediate representation for the source code in the first version to a number of optimization paths, wherein the number of optimization paths are data structures that comprise information for converting the source code in the first version to the source code in a second version, and wherein the number of optimization paths are stored as mappings between fragments of the intermediate representation and corresponding portions of the source code in the second version of the source code in an optimization path library;
identifying, by the processor set, a number of matches based on the comparisons, wherein each match from the number of matches comprises a fragment of the intermediate representation and corresponding portion of the source code in the second version for the fragment of the intermediate representation based on an optimization path from the number of optimization paths stored in the optimization path library;
and
updating, by the processor set, at least a portion of the source code in the first version to the second version based on the number of matches to generate the source code in the second version.

identify a number of matches based on the comparisons, wherein each match from the number of matches comprises a fragment of the intermediate representation and corresponding portion of the source code in the second version for the fragment of the intermediate representation based on an optimization path from the number of optimization paths stored in the optimization path library;
and
update at least a portion of the source code in the first version to the second version based on the number of matches to generate the source code in the second version.
