C++ Name Mangling Decoder for G++?

c++filt, example usage here:

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

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 If it exists, there is SaaS of it.

nm also has a -C option.

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…]
