C++ name mangling by hand

I am writing a script for the IDA Pro disassembler in Python using the idapython plugin. Using this, I am able to fill in the gaps where IDA's auto-analysis falls short.

One area that has me stumped is naming locations/functions with (for want of a better term) "pretty names". An example of what I mean is illustrated below:

idapython and IDA Pro itself only allow me to enter basic C-ish function names. If I enter disallowed symbols (e.g. the scope resolution operator), they're replaced with underscores. However, if I enter a mangled name by hand (e.g. __ZN9IOService15powerChangeDoneEm), IDA Pro will prettify this for me.

Hence my question: how can I generate mangled names to pass through idapython? Is there a name-mangling library available? Is one available in Python? Is my only hope to tear the mangling functionality out of g++ and work around that?

Solution

  • I finally got around to dig a little.

    Unfortunately I could not find tool, I did find resources though.

    If all you want is mangle names in the gcc3 fashion, then know that gcc3 use the Itanium C++ ABI, which has a standardized name mangling scheme. I found two documents:

    For reference, both come from the Wikipedia page on Name Mangling.
