Getting mangled name from demangled name

Is there any way to get back the mangled name from demangled name in g++.

For example , I have the demangled name func(char*, int), what should I do to get the mangled name i.e _Z4funcPci back?

My question is g++ specific.

Solution

  • You can simply use g++ to compile an empty function with the signature you require and extract the name from that. For example:

    echo "int f1(char *, int) {} " | g++ -x c++ -S - -o- | grep "^_.*:$" | sed -e 's/:$//'

    gives output

    _Z2f1Pci

    which is I think what you require. Make sure that you include any relevant header files as they will affect the way the symbols are mangled.
