Trucov
Trucov is an open source code coverage analysis tool for GCC versions 4.0 and later that aims to be a gcov replacement. Trucov improves upon gcov by providing more granular and machine readable output, such as DOT Files representing control-flow graph of the program. The use of DOT Files allows for other common tools like GraphViz to be used to produce coverage graphs. Trucov was developed as a senior design project at Washington State University.
