InstructionCounter plugin for IDA Pro

Author: sp

# Views: 1655

The InstructionCounter plugin for IDA Pro is actually the first plugin Ive ever succesfully finished. The main reason for this is probably that its not exactly a very complicated plugin but basically a copy / paste of the template code from Steve Micallefs awesome IDA plugin tutorial with just a few extra lines added.

The plugin counts all instructions used in a file, orders them by their frequency of occurrence and prints all that information to a text file of your choice.

Heres what the output looks like:

The ZIP file contains the complete Visual C++ source code and the compiled plugin for IDA 4.8 and IDA 4.9.

There are two minor problems Im having which are mentioned in the source file. Unfortunately none of the people I bug about my IDA problems have been online in the last few days.

Furthermore I was convinced that a plugin like that already exists but I didnt find anything at the IDA Palace when I needed it a few days ago. If theres really already a plugin like that let me know.
