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. 

Features
Produces coverage analysis on a per source, per function, and per branch level
Provides both textual and graphical coverage reports that are easier to use and understand
Automatically finds all the source files inside of a project
Detects how many times a particular block or branch of code has been executed
Generates the control flow graph of each function per source file
Optionally hides coverage information of external libraries to better focus on the product under test
Allows user to narrow the scope of coverage information by specifying specific functions or files
