LLVM-CXXFILT(1) LLVM LLVM-CXXFILT(1) 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 deman- gled, 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-de- tect 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 plat- forms 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. SEE ALSO llvm-nm(1) AUTHOR Maintained by the LLVM Team (https://llvm.org/).
