<h3>NAME</h3>
|
|
<tt>llvm-nm</tt>
|
|
|
|
<h3>SYNOPSIS</h3>
|
|
<tt>llvm-nm [options] [filenames...]</tt>
|
|
|
|
<h3>DESCRIPTION</h3>
|
|
|
|
<p>The <tt>llvm-nm</tt> utility lists the names of symbols from the
|
|
LLVM bytecode files, or <tt>ar(1)</tt> archives containing LLVM
|
|
bytecode files, named on the command line. Each symbol is listed along
|
|
with some simple information about its provenance. If no filename is specified,
|
|
or - is used as a filename, <tt>llvm-nm</tt> will process a bytecode file
|
|
on its standard input stream.</p>
|
|
|
|
<p><tt>llvm-nm</tt>'s default output format is the traditional BSD
|
|
<tt>nm(1)</tt> output format. Each such output record consists of an
|
|
(optional) 8-digit hexadecimal address, followed by a type code
|
|
character, followed by a name, for each symbol. One record is printed
|
|
per line; fields are separated by spaces. When the address is omitted,
|
|
it is replaced by 8 spaces.</p>
|
|
|
|
<p>Type code characters currently supported, and their meanings, are
|
|
as follows:</p>
|
|
|
|
<table border>
|
|
<tr><td>U</td><td>Named object is referenced but undefined in this
|
|
bytecode file</td></tr>
|
|
<tr><td>C</td><td>Common (multiple defs link together into one
|
|
def)</td></tr>
|
|
<tr><td>W</td><td>Weak reference (multiple defs link together into zero or
|
|
one defs)</td></tr>
|
|
<tr><td>t</td><td>Local function (text) object</td></tr>
|
|
<tr><td>T</td><td>Global function (text) object</td></tr>
|
|
<tr><td>d</td><td>Local data object</td></tr>
|
|
<tr><td>D</td><td>Global data object</td></tr>
|
|
<tr><td>?</td><td>Something unrecognizable</td></tr>
|
|
</table>
|
|
|
|
<p>Because LLVM bytecode files typically contain objects that are not
|
|
considered to have addresses until they are linked into an executable
|
|
image or dynamically compiled "just-in-time", <tt>llvm-nm</tt> does
|
|
not print an address for any symbol, even symbols which are defined in
|
|
the bytecode file.</p>
|
|
|
|
<h3>OPTIONS</h3>
|
|
|
|
<ul>
|
|
<li> -P
|
|
<br>
|
|
Use POSIX.2 output format. Alias for --format=posix.
|
|
<p>
|
|
<li> -B (default)
|
|
<br>
|
|
Use BSD output format. Alias for --format=bsd.
|
|
<p>
|
|
|
|
<li> -help
|
|
<br>
|
|
Print a summary of command-line options and their meanings.
|
|
<p>
|
|
|
|
<li> -defined-only
|
|
<br>
|
|
Print only symbols defined in this bytecode file (as opposed
|
|
to symbols which may be referenced by objects in this file,
|
|
but not defined in this file.)
|
|
<p>
|
|
|
|
<li> -extern-only, -g
|
|
<br>
|
|
Print only symbols whose definitions are external; that is,
|
|
accessible from other bytecode files.
|
|
<p>
|
|
|
|
<li> -undefined-only, -u
|
|
<br>
|
|
Print only symbols referenced but not defined in this bytecode
|
|
file.
|
|
<p>
|
|
|
|
<li> -format=<i>fmt</i>, -f
|
|
<br>
|
|
Select an output format; <i>fmt</i> may be sysv, posix, or
|
|
bsd. The default is bsd.
|
|
<p>
|
|
</ul>
|

|
<h3>BUGS</h3>
|
|
|
|
<tt>llvm-nm</tt> cannot demangle C++ mangled
|
|
names, like GNU <tt>nm(1)</tt> can.
|
|
|
|
<h3>EXIT STATUS</h3>
|
|
|
|
<tt>llvm-nm</tt> exits with an exit code of zero.
