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 开发者_如何学Gog++ and work around that?

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:

• The Itanium C++ ABI page
• A Calling Convention PDF document, which describe the schemes of various compilers

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

One simple (alebit hacky) method would be to compile a C++ file with the symbol you want in it, then extract the necessary symbols from the .o file's symbol table. With a bit of work this might be nicely scriptable.

Here is an article that explains how mangling is done by Visual compiler. For mangling done by gcc, I think you can find the information in the source of the binutils package.

You can use the Clang AST library, which has a MangleContext class.
