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 interac-
tively 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 alphanu-
meric, ‘.’, ‘$’, 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.
