3# This script is a wrapper for OS X nm(1) tool. nm(1) perform C++ function
4# names demangling, so we're piping its output to c++filt(1) tool which does it.
5# But c++filt(1) comes with XCode (as a part of GNU binutils), so it doesn't
6# guaranteed to exist on a system.
7#
8# An alternative approach is to perform demangling in tick processor, but
9# for GNU C++ ABI this is a complex process (see cp-demangle.c sources), and
10# can't be done partially, because term boundaries are plain text symbols, such
11# as 'N', 'E', so one can't just do a search through a function name, it really
12# needs to be parsed, which requires a lot of knowledge to be coded in.
