<!-- man begin DESCRIPTION addr2line -->
|
|
<p><span class="command">addr2line</span> translates addresses into file names and line numbers.
|
|
Given an address in an executable or an offset in a section of a relocatable
|
|
object, it uses the debugging information to figure out which file name and
|
|
line number are associated with it.
|
|
|
|
<p>The executable or relocatable object to use is specified with the <span class="option">-e</span>
|
|
option. The default is the file <span class="file">a.out</span>. The section in the relocatable
|
|
object to use is specified with the <span class="option">-j</span> option.
|
|
|
|
<p><span class="command">addr2line</span> has two modes of operation.
|
|
|
|
<p>In the first, hexadecimal addresses are specified on the command line,
|
|
and <span class="command">addr2line</span> displays the file name and line number for each
|
|
address.
|
|
|
|
<p>In the second, <span class="command">addr2line</span> reads hexadecimal addresses from
|
|
standard input, and prints the file name and line number for each
|
|
address on standard output. In this mode, <span class="command">addr2line</span> may be used
|
|
in a pipe to convert dynamically chosen addresses.
|
|
|
|
<p>The format of the output is <span class="samp">FILENAME:LINENO</span>. The file name and
|
|
line number for each address is printed on a separate line. If the
|
|
<span class="command">-f</span> option is used, then each <span class="samp">FILENAME:LINENO</span> line is
|
|
preceded by a <span class="samp">FUNCTIONNAME</span> line which is the name of the function
|
|
containing the address.
|
|
|
|
<p>If the file name or function name can not be determined,
|
|
<span class="command">addr2line</span> will print two question marks in their place. If the
|
|
line number can not be determined, <span class="command">addr2line</span> will print 0.
|
|
|

<!-- man begin OPTIONS addr2line -->

<p>The long and short forms of options, shown here as alternatives, are
|
|
equivalent.

|
|
Besides removing any initial underscore prepended by the system, this
|
|
makes C++ function names readable. Different compilers have different
|
|
mangling styles. The optional demangling style argument can be used to
|
|
choose an appropriate demangling style for your compiler. See <a href="c_002b_002bfilt.html#c_002b_002bfilt">c++filt</a>,
|
|
for more information on demangling.
