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-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.
