1llvm-cxxfilt - LLVM symbol name demangler2=========================================3 4.. program:: llvm-cxxfilt5 6SYNOPSIS7--------8 9:program:`llvm-cxxfilt` [*options*] [*mangled names...*]10 11DESCRIPTION12-----------13 14:program:`llvm-cxxfilt` is a symbol demangler that can be used as a replacement15for the GNU :program:`c++filt` tool. It takes a series of symbol names and16prints their demangled form on the standard output stream. If a name cannot be17demangled, it is simply printed as is.18 19If no names are specified on the command-line, names are read interactively from20the standard input stream. When reading names from standard input, each input21line is split on characters that are not part of valid Itanium name manglings,22i.e. characters that are not alphanumeric, '.', '$', or '_'. Separators between23names are copied to the output as is.24 25EXAMPLE26-------27 28.. code-block:: console29 30 $ llvm-cxxfilt _Z3foov _Z3bari not_mangled31 foo()32 bar(int)33 not_mangled34 $ cat input.txt35 | _Z3foov *** _Z3bari *** not_mangled |36 $ llvm-cxxfilt < input.txt37 | foo() *** bar(int) *** not_mangled |38 39OPTIONS40-------41 42.. option:: --format=<value>, -s43 44 Mangling scheme to assume.
