Method for performing conditionalized N-way merging of source code

摘要

A method combines N versions of a C/C++ program into a single, semantically correct, unified program, while maintaining the semantics of each version within N. The problem of merge conflicts is avoided by conditionalizing changes that potentially conflict, according to a set of preprocessors definitions that uniquely define the version within N. Conditionalization is realized through C/C++ preprocessing directives (e.g., #if, #else, #elif).
