C++ name mangling by hand

Question

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.

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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