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