[DynInst_API:] Code Coverage Tool

Hi All, I am trying to find/ implement a tool which can collect basic code coverage information (specifically number of times each function was executed and the average execution time). I was searching through the dyninst site and found the project codeCoverage listed in related projects which

Hi All, I am thinking of implementing a control flow integrity prototype for which I require doing some static analysis to approximate control flow targets of indirect control flow instructions. How does parseAPI handle indirect control flows when deriving the CFG? What facilities does the API
