No. It only tells you that the original symbol in the current def file is
missing in the binary, not the new symbol need to be in the def file.

Just used the following method on Linux:

1. build and install libmangle (

2. compile and run the following program:

#include <stdio.h>
#include <libmangle.h>

<decode_mangle function copied from

int main(int argc, char* argv[]) {
  for (int i = 1; i < argc; ++i)
    decode_mangle(stdout, argv[i]);
  return 0;

Though the program can only decode a mangled symbol, we can use it to check
if a manually mangled name is as expected.
