IDA or a plugin for ?

[ChupaChu]

Hey Louzew, have you checked this plugin:
http://www.openrce.org/downloads/details/187/ida_struct

I did not use it, but short nfo says:

idastruct is an ida plugin which aims to assist reverse engineers in identifying high-level objects and structures in binary code.

idastruct utilizes the excellent x86 emulator plugin 'ida-x86emu' by Chris Eagle and Jermey Cooper as a basis for evaluating operand values and determining references within tracked boundaries.

This results in automated creation of IDA structures, enumeration or member references, and renaming of disassembly offsets to symbolic names corresponding to the newly created structures and members in the IDA database.

Hope it helps!

BR, ChupaChu!
