arm-gp2x-linux-c++filt: Demangle C++ and Java symbols.
NAMEc++filt - Demangle C++ and Java symbols.
DESCRIPTIONThe 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:
- 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 low-level 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 C++ syntax.
- Do not remove the initial underscore.
- When demangling the name of a function, do not display the types of the function's parameters.
- -s format
c++filt can decode various methods of mangling, used by
different compilers. The argument to this option selects which
method it uses:
- Automatic selection based on executable (the default method)
- the one used by the GNU C++ compiler (g++)
- the one used by the Lucid compiler (lcc)
- the one specified by the C++ Annotated Reference Manual
- the one used by the HP compiler (aCC)
- the one used by the EDG compiler
- the one used by the GNU C++ compiler (g++) with the V3 ABI.
- the one used by the GNU Java compiler (gcj)
- the one used by the GNU Ada compiler (GNAT).
- Print a summary of the options to c++filt and exit.
- Print the version number of c++filt and exit.
- MS-DOS does not allow "+" characters in file names, so on MS-DOS this program is named CXXFILT.
