ABSTRACT:
A system which scans and parses input source code of a computer programming language during a first pass, and saves the parse states to be replayed during a second pass. Therefore, the source file is not rescanned nor is it reparsed during the second pass. The parse states are replayed during the second pass, reexecuting all the parser actions in the grammar in the same order during the second pass that they were originally recorded during the actual parsing in the first pass. This eliminates the need to rescan and reparse the original input language, reducing the processing time of the compiler. The user specifies what code is to be executed during each pass, and the system also provides facilities for communication between the passes.
