Hotch 1.0.0 - named after everyone's favourite TV profiler - is an IDA plugin that can be used to profile binary files. It sets breakpoints on all basic blocks of a program, records breakpoints hits and tries to figure out statistics from these hits. Click here to seen an example of a simple profiling session (starting Notepad and exiting Notepad again). Click here to see a huge 6.5 MB results file that shows a larger profiling session (loading a file in Notepad and playing around in it).
Random Notes:
"This is really slow for larger files". Yeah, it is really slow in IDA up to 5.2 but Ilfak fixed some things in IDA 5.3 and it works acceptably fast now. So patience, young padawan. "The timing results don't really make sense". Yeah, I know. Since I execute a callback function after each breakpoint hit tight loops take disproportionally much time. For anything but tight loops the timing results should kinda work, at least relative to each other of course. Ignore the source file libida.hpp, it's an early version of my experimental-at-best C++ wrapper library for the IDA SDK. I take feature requests for Hotch.
