Similar to D104889. The tool is very simple and its long options are uncommon, so just drop the one-dash form in this patch. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D105605

llvm-cxxfilt - LLVM symbol name demangler
|
|
=========================================
|
|
|
|
.. program:: llvm-cxxfilt
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-cxxfilt` [*options*] [*mangled names...*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
:program:`llvm-cxxfilt` is a symbol demangler that can be used as a replacement
|
|
for the GNU :program:`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
|
|
-------
|
|
|
|
.. code-block:: console
|
|
|
|
$ 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
|
|

|
|
|
|
.. option:: --format=<value>, -s
|

|
|
|
|
.. option:: --strip-underscore, -_
|
|
|
|
Strip a single leading underscore, if present, from each input name before
|
|
demangling. On by default on Mach-O based platforms.
|
|
|
|
.. option:: --types, -t
|
|
|
|
Attempt to demangle names as type names as well as function names.
|
|
|
|
.. option:: --version
|
