<p>The demangling is performed using the C++ ABI mangling rules, with GNU extensions. For example, this function is used in __gnu_cxx::__verbose_terminate_handler.</p>
<p>See <a href="https://gcc.gnu.org/onlinedocs/libstdc++/manual/ext_demangling.html">https://gcc.gnu.org/onlinedocs/libstdc++/manual/ext_demangling.html</a> for other examples of use.</p>
<dl class="section note"><dt>Note</dt><dd>The same demangling functionality is available via libiberty (<code><libiberty/demangle.h></code> and <code>libiberty.a</code>) in GCC 3.1 and later, but that requires explicit installation (<code>–enable-install-libiberty</code>) and uses a different API, although the ABI is unchanged. </dd></dl>
