|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility translates program addresses specified by the command line
|
|
arguments
|
|
.Ar hexaddress
|
|
to their corresponding source file names and line numbers.
|
|
If no arguments are given to
|
|
.Nm ,
|
|
it will read these addresses from standard input.
|
|
.Pp
|
|
Program addresses specified by arguments
|
|
.Ar hexaddress
|
|
are encoded using the conventions accepted by
|
|
.Xr strtoull 3 .
|
|
.Pp
|
|
By default,
|
|
.Nm
|
|
will use the executable
|
|
.Dq Pa a.out .
|
|
The
|
|
.Fl e
|
|
option may be used to specified a different ELF object.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility recognizes the following options:
|
|
.Bl -tag -width indent
|
|
.It Fl a | Fl -addresses
|
|
Display the address prior to the line number information.
|
|
.It Fl b Ar target | Fl -target Ns = Ns Ar target
|
|
This option is recognized by
|
|
.Nm
|
|
but is ignored.
|
|
It is supported for compatibility with GNU binutils.
|
|
.It Fl e Ar pathname | Fl -exe Ns = Ns Ar pathname
|
|
Use the ELF object specified by argument
|
|
.Ar pathname
|
|
to translate addresses.
|
|
If this option is not specified,
|
|
.Nm
|
|
will use the file
|
|
.Dq Pa a.out .
|
|
.It Fl f | Fl -functions
|
|
Display function names in addition to file and line number information.
|
|
.It Fl i | Fl -inlines
|
|
If the address specified belongs to an inlined function, also display the line
|
|
number information for its caller, recursively until the first non-inlined
|
|
caller.
|
|
.It Fl j Ar sectionname | Fl -section Ns = Ns Ar sectionname
|
|
The values specified by arguments
|
|
.Ar hexaddress
|
|
are to be treated as offsets into the section named
|
|
.Ar sectionname .
|
|
.It Fl p | -pretty-print
|
|
Display the line number information on one line, in human readable manner.
|
|
.It Fl s | -basename
|
|
Display only the base name for each file name.
|
|
.It Fl C | Fl -demangle
|
|
Demangle C++ names.
|
|
.It Fl H | Fl -help
|
|
Print a help message.
|
|
.It Fl V | Fl -version
|
|
Print a version identifier and exit.
|
|
.El
|
|
.Sh OUTPUT FORMAT
|
|
If the
|
|
.Fl f
|
|
option was not specified,
|
|
.Nm
|
|
will print the file name and line number for each address specified
|
|
on a separate line.
|
|
.Pp
|
|
If the
|
|
.Fl f
|
|
option was specified,
|
|
.Nm
|
|
will print a line containing the name of the function corresponding
|
|
to program address
|
|
.Ar hexaddress ,
|
|
followed by a line with the file name and line number.
|
|
.Pp
|
|
If the
|
|
.Fl p
|
|
option was specified,
|
|
.Nm
|
|
will print line number information and function name on one line in
|
|
human readable manner. If the
|
|
.Fl i
|
|
option was also specified,
|
|
.Nm
|
|
will print the caller function information prefixed with
|
|
.Dq (inlined by) .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility prints the file name and line number using the format
|
|
.Dq FILENAME:LINENUMBER .
|
|
.Pp
|
|
If a file or function name could not be determined,
|
|
.Nm
|
|
will print a question mark in their place.
|
|
If the line number could not be determined,
|
|
.Nm
|
|
will print a zero in its place.
|
|
.Sh EXAMPLES
|
|
To map address 080483c4 in the default executable
|
|
.Pa a.out
|
|
to a source file name and line number use:
|
|
.D1 "% addr2line 080483c4"
|
|
.Pp
|
|
To map address 080483c4 in executable
|
|
.Pa helloworld ,
|
|
use:
|
|
.D1 "% addr2line -e helloworld 080483c4"
|
|
.Pp
|
|
To have
|
|
.Nm
|
|
act as a filter reading addresses from its standard input use:
|
|
.D1 "% addr2line"
|
|
.Pp
|
|
To print the function name corresponding to an address in addition to
|
|
its source file and line number use:
|
|
.D1 "% addr2line -f 080483c4"
