.SH DESCRIPTION
|
|
\c
|
|
.B addr2line
|
|
translates program addresses into file names and line numbers. Given
|
|
an address and an executable, it uses the debugging information in the
|
|
executable to figure out which file name and line number are
|
|
associated with a given address.
|
|
|
|
The executable to use is specified with the
|
|
.B \-e
|
|
option. The default is
|
|
.B a.out\c
|
|
\&.
|
|
|
|
.B addr2line
|
|
has two modes of operation.
|
|
|
|
In the first, hexadecimal addresses are specified on the command line,
|
|
and
|
|
.B addr2line
|
|
displays the file name and line number for each address.
|
|
|
|
In the second,
|
|
.B addr2line
|
|
reads hexadecimal addresses from standard input, and prints the file
|
|
name and line number for each address on standard output. In this
|
|
mode,
|
|
.B addr2line
|
|
may be used in a pipe to convert dynamically chosen addresses.
|
|
|
|
The format of the output is FILENAME:LINENO. The file name and line
|
|
number for each address is printed on a separate line. If the
|
|
.B \-f
|
|
option is used, then each FILENAME:LINENO line is preceded by a
|
|
FUNCTIONNAME line which is the name of the function containing the
|
|
address.
|
|
|
|
If the file name or function name can not be determined,
|
|
.B addr2line
|
|
will print two question marks in their place. If the line number can
|
|
not be determined,
|
|
.B addr2line
|
|
will print 0.

.SH OPTIONS
|
|
.TP
|
|
.BI "\-b " "bfdname"\c
|
|
.TP
|
|
.BI "\-\-target=" "bfdname"
|
|
Specify the object-code format for the object files to be
|
|
\c
|
|
.I bfdname\c
|
|
\&.
|
|
|
|
.TP
|
|
.B \-C
|
|
.TP
|
|
.B \-\-demangle
|
|
Decode (\fIdemangle\fP) low-level symbol names into user-level names.
|
|
Besides removing any initial underscore prepended by the system, this
|
|
makes C++ function names readable.
|
|
|
|
.TP
|
|
.BI "\-e " "filename"\c
|
|
.TP
|
|
.BI "\-\-exe=" "filename"
|
|
Specify the name of the executable for which addresses should be
|
|
translated. The default file is
|
|
.B a.out\c
|
|
\&.
|
|
|
|
.TP
|
|
.B \-f
|
|
.TP
|
|
.B \-\-functions
|
|
Display function names as well as file and line number information.
|
|
|
|
.TP
|
|
.B \-s
|
|
.TP
|
|
.B \-\-basenames
|
|
Display only the base of each file name.
