Each symbol is listed along with some simple information about its provenance. If no file name is specified, or <em>-</em> is used as a file name, <strong>llvm-nm</strong> will process a bitcode file on its standard input stream.</p> <p><strong>llvm-nm</strong>'s default output format is the traditional BSD <strong>nm</strong> 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> <dl> <dt><strong><a name="u" class="item">U</a></strong></dt> <dd> <p>Named object is referenced but undefined in this bitcode file</p> </dd> <dt><strong><a name="c" class="item">C</a></strong></dt> <dd> <p>Common (multiple definitions link together into one def)</p> </dd> <dt><strong><a name="w" class="item">W</a></strong></dt> <dd> <p>Weak reference (multiple definitions link together into zero or one definitions)</p> </dd> <dt><strong><a name="t" class="item">t</a></strong></dt> <dd> <p>Local function (text) object</p> </dd> <dt><strong><a name="t" class="item">T</a></strong></dt> <dd> <p>Global function (text) object</p> </dd> <dt><strong><a name="d" class="item">d</a></strong></dt> <dd> <p>Local data object</p> </dd> <dt><strong><a name="d" class="item">D</a></strong></dt> <dd> <p>Global data object</p> </dd> <dt><strong><a name="" class="item">?</a></strong></dt> <dd> <p>Something unrecognizable</p> </dd> </dl> <p>Because LLVM bitcode 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", <strong>llvm-nm</strong> does not print an address for any symbol, even symbols which are defined in the bitcode file.</p> <p> </p> <hr /> <h1><a name="options">OPTIONS</a></h1> <dl> <dt><strong><a name="p" class="item"><strong>-P</strong></a></strong></dt> <dd> <p>Use POSIX.2 output format.
