|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility translates encoded C++ symbol names to human-readable form.
|

.Nm
|
|
utility has two operating modes.
|
|
.Bl -bullet
|
|
.It
|
|
If arguments
|
|
.Ar encoded-names
|
|
are not specified, then
|
|
.Nm
|
|
will act as a filter, reading from standard input
|
|
and writing to standard output.
|
|
.It
|
|
If arguments
|
|
.Ar encoded-names
|
|
are specified, then
|
|
.Nm
|
|
will decode each such argument in turn, writing its decoded form
|
|
to standard output.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility recognizes the following options:
|
|

|
|
.It Fl -help
|
|
Print a help message and exit.
|
|
.It Fl _ | Fl -strip-underscores
|
|
Remove a leading underscore from symbol names prior to decoding them.
|
|
.It Fl n | Fl -no-strip-underscores
|
|
Do not remove leading underscores from names.
|
|
.It Fl p | Fl -no-params
|

|
|
.It Fl s Ar scheme | Fl -format Ns = Ns Ar scheme
|
|
Select the encoding scheme to use.
|
|
Argument
|
|
.Ar scheme
|
|
can be one of the following:
|
|
.Bl -tag -width "gnu-v5"
|
|
.It Ar arm
|
|
Use the encoding scheme specified by the C++ Annotated Reference Manual.
|
|
.It Ar auto
|
|
Guess the encoding scheme from the input.
|
|
.It Ar gnu
|
|
Use the encoding scheme used by the GNU C++ compiler.
|
|
.It Ar gnu-v3
|
|
Use the encoding scheme used by the GNU C++ compiler, version 3.
|
|
.El
|
|
.It Fl V | Fl -version
