c++filt - Demangle C++ and Java symbols.
[--help] [--version] [symbol...]
The C++ and Java languages provides function overloading, which means
that you can write many functions with the same name (providing each
takes parameters of different types). All C++ and Java function names
are encoded into a low-level assembly label (this process is known as
mangling). The c++filt  program does the inverse mapping: it decodes
(demangles) low-level names into user-level names so that the linker
can keep these overloaded functions from clashing.
Every alphanumeric word (consisting of letters, digits, underscores,
dollars, or periods) seen in the input is a potential label. If the
label decodes into a C++ name, the C++ name replaces the low-level name
in the output.
You can use c++filt to decipher individual symbols:
If no symbol arguments are given, c++filt reads symbol names from the
standard input and writes the demangled names to the standard output.
All results are printed on the standard output.
On some systems, both the C and C++ compilers put an underscore in
front of every name. For example, the C name "foo" gets the lowlevel
name "_foo". This option removes the initial underscore.
Whether c++filt removes the underscore by default is target dependent.
Prints demangled names using Java syntax. The default is to use
Do not remove the initial underscore.
GNU nm can decode three different methods of mangling, used by different
C++ compilers. The argument to this option selects which
method it uses:
the one used by the GNU compiler (the default method)
the one used by the Lucid compiler
the one specified by the C++ Annotated Reference Manual
the one used by the HP compiler
the one used by the EDG compiler
the one used by the GNU compiler with the new ABI.
Print a summary of the options to c++filt and exit.
Print the version number of c++filt and exit.

this program is named c++filt.
