NAME

       llvm-cxxfilt - LLVM symbol name demangler

SYNOPSIS

       llvm-cxxfilt [options] [mangled names...]

DESCRIPTION

       llvm-cxxfilt  is  a symbol demangler that can be used as a replacement for the GNU c++filt
       tool. It takes a series of symbol names and prints their demangled form  on  the  standard
       output stream. If a name cannot be demangled, it is simply printed as is.

       If  no  names  are  specified  on  the command-line, names are read interactively from the
       standard input stream. When reading names from standard input, each input line is split on
       characters that are not part of valid Itanium name manglings, i.e. characters that are not
       alphanumeric, '.', '$', or '_'. Separators between names are copied to the output as is.

EXAMPLE

          $ llvm-cxxfilt _Z3foov _Z3bari not_mangled
          foo()
          bar(int)
          not_mangled
          $ cat input.txt
          | _Z3foov *** _Z3bari *** not_mangled |
          $ llvm-cxxfilt < input.txt
          | foo() *** bar(int) *** not_mangled |

OPTIONS

       --format=<value>, -s
              Mangling scheme to assume. Valid values are auto (default, auto-detect  the  style)
              and gnu (assume GNU/Itanium style).

       --help, -h
              Print a summary of command line options.

       --no-params, -p
              Do not demangle function parameters or return types.

       --no-strip-underscore, -n
              Do  not  strip  a  leading underscore. This is the default for all platforms except
              Mach-O based hosts.

       --strip-underscore, -_
              Strip a single  leading  underscore,  if  present,  from  each  input  name  before
              demangling. On by default on Mach-O based platforms.

       --types, -t
              Attempt to demangle names as type names as well as function names.

       --version
              Display the version of the llvm-cxxfilt executable.

       @<FILE>
              Read command-line options from response file <FILE>.

EXIT STATUS

       llvm-cxxfilt  returns  0 unless it encounters a usage error, in which case a non-zero exit
       code is returned.
