Here is one small, and (I hope) useful tool. What it will do is to use Pin to trace execution flow of an application, and count how many times instructions are executed. This will produce log file, which later can be imported in ida via ida plugin, and highlight code which is executed. Of course, code which is executed more will have darker highlight, and ones which are executed less will have brighter color. Tool itself is very simple, so I don't even dare to call it project It supports x32/x64 both Linux, and Windows Link with source code : http://deroko.phearless.org/pinlog.zip
