It takes a series of symbol names and 1609467b48Spatrickprints their demangled form on the standard output stream. If a name cannot be 1709467b48Spatrickdemangled, it is simply printed as is. 1809467b48Spatrick 1909467b48SpatrickIf no names are specified on the command-line, names are read interactively from 2009467b48Spatrickthe standard input stream. When reading names from standard input, each input 2109467b48Spatrickline is split on characters that are not part of valid Itanium name manglings, 2209467b48Spatricki.e. characters that are not alphanumeric, '.', '$', or '_'. Separators between 2309467b48Spatricknames are copied to the output as is. 2409467b48Spatrick 2509467b48SpatrickEXAMPLE 2609467b48Spatrick------- 2709467b48Spatrick 2809467b48Spatrick.. code-block:: console 2909467b48Spatrick 3009467b48Spatrick $ llvm-cxxfilt _Z3foov _Z3bari not_mangled 3109467b48Spatrick foo() 3209467b48Spatrick bar(int) 3309467b48Spatrick not_mangled 3409467b48Spatrick $ cat input.txt 3509467b48Spatrick | _Z3foov *** _Z3bari *** not_mangled | 3609467b48Spatrick $ llvm-cxxfilt < input.txt 3709467b48Spatrick | foo() *** bar(int) *** not_mangled | 3809467b48Spatrick 3909467b48SpatrickOPTIONS 4009467b48Spatrick------- 4109467b48Spatrick 4209467b48Spatrick.. option:: --format=<value>, -s 4309467b48Spatrick 4409467b48Spatrick Mangling scheme to assume.
