C++ name mangling decoder for g++?

Question

is there any C++ name-mangling decoder for g++?

Some guys will soon answer c++filt – Anodic

Voting to reopen: #4466372 clearly requires it to be from inside the code, and only for types, which never appear on object files (as opposed to functions). This one is usually interpreted as "on object files from the command line". – Houppelande

it old but I have been helped by this site a lot demangler.com – Predigestion

Answer 1

You can use c++filt to demangle c++ symbols. For instance

$ c++filt -n _Z1fv
f()

Answer 2

c++filt, example usage here:

Can we see the template instantiated code by C++ compiler

Answer 3

You may also be interested on the -C option of objdump:

objdump -CSr main.o

which demangles relocation references like:

  char *sn = new char[4];
10:   bf 04 00 00 00          mov    $0x4,%edi
15:   e8 00 00 00 00          callq  1a <main+0x1a>
                      16: R_X86_64_PC32       operator new[](unsigned long)-0x4

Without -C it would show the mangled name _Znam.

There are also some online demanglers mentioned at Is there an online name demangler for C++? like http://demangler.com/ If it exists, there is SaaS of it.

nm also has a -C option.

or even objdump -CSr main.o | less --pattern=_Znam – Koser

Answer 4

you have c++filt. Recently I found an online tool as well.

1.

c++filt [-_|--strip-underscore]
        [-n|--no-strip-underscore]
        [-p|--no-params]
        [-t|--types]
        [-i|--no-verbose]
        [-r|--no-recurse-limit]
        [-R|--recurse-limit]
        [-s format|--format=format]
        [--help]  [--version]  [symbol…]

Example: c++filt symbol
