1llvm-cxxfilt - LLVM symbol name demangler 2========================================= 3 4.. program:: llvm-cxxfilt 5 6SYNOPSIS 7-------- 8 9:program:`llvm-cxxfilt` [*options*] [*mangled names...*] 10 11DESCRIPTION 12----------- 13 14:program:`llvm-cxxfilt` is a symbol demangler that can be used as a replacement 15for the GNU :program:`c++filt` tool. It takes a series of symbol names and 16prints their demangled form on the standard output stream. If a name cannot be 17demangled, it is simply printed as is. 18 19If no names are specified on the command-line, names are read interactively from 20the standard input stream. When reading names from standard input, each input 21line is split on characters that are not part of valid Itanium name manglings, 22i.e. characters that are not alphanumeric, '.', '$', or '_'. Separators between 23names are copied to the output as is. 24 25EXAMPLE 26------- 27 28.. code-block:: console 29 30 $ llvm-cxxfilt _Z3foov _Z3bari not_mangled 31 foo() 32 bar(int) 33 not_mangled 34 $ cat input.txt 35 | _Z3foov *** _Z3bari *** not_mangled | 36 $ llvm-cxxfilt < input.txt 37 | foo() *** bar(int) *** not_mangled | 38 39OPTIONS 40------- 41 42.. option:: --format=<value>, -s 43 44 Mangling scheme to assume. Valid values are ``auto`` (default, auto-detect the 45 style) and ``gnu`` (assume GNU/Itanium style). 46 47.. option:: --help, -h 48 49 Print a summary of command line options. 50 51.. option:: --no-params, -p 52 53 Do not demangle function parameters or return types. 54 55.. option:: --no-strip-underscore, -n 56 57 Do not strip a leading underscore. This is the default for all platforms 58 except Mach-O based hosts. 59 60.. option:: --quote 61 62 Add `"` `"` around demangled names. Do not quote already quoted names. 63 64.. option:: --strip-underscore, -_ 65 66 Strip a single leading underscore, if present, from each input name before 67 demangling. On by default on Mach-O based platforms. 68 69.. option:: --types, -t 70 71 Attempt to demangle names as type names as well as symbol names. 72 73.. option:: --version 74 75 Display the version of the :program:`llvm-cxxfilt` executable. 76 77.. option:: @<FILE> 78 79 Read command-line options from response file `<FILE>`. 80 81EXIT STATUS 82----------- 83 84:program:`llvm-cxxfilt` returns 0 unless it encounters a usage error, in which 85case a non-zero exit code is returned. 86 87SEE ALSO 88-------- 89 90:manpage:`llvm-nm(1)` 91
