Abstract
A program analysis support device that can freely combine program analysis conditions and can realize desired program analysis. An analysis condition setting part inputs a program analysis condition in a form of a conditional equation (analysis command, an analysis subject, and analysis condition) having an inherent equation number. A POU list extraction processing executing part executes an analysis command that reads a program to generate a collection of POUs serving as analysis subjects constituting the program, and a variable use list extraction processing executing part executes an analysis command that extracts a cross-reference of a variable to extract a cross-reference of a variable to the POU collection serving as the analysis subject. Both the parts further extract a cross-reference of a variable to another POU collection. An AND processing part further performs processing of a logical product of the cross-references of both the variables and outputs a result thereof to an analysis result display part.
