Add to ORKGWe have developed a software tool called Z1 by which one can quickly achieve an accurate yet affordable program analysis. The user writes an analysis specification and sets a parameter for a desired cost-accuracy tradeoff. The tool then creates an executable analyzer that has the specified performance balance. Z1 has been used for developing both conventional and non-conventional flow analyses. These analyses were for programs written in C, FORTRAN, and Standard ML, without restriction upon the programs treated. We present experimental data showing the performances of Z1 for analyzing C, FORTRAN, and Standard ML programs.
