<p><a name="index-g_t_0040code_007bfunc_007d-directive-346"></a><code>.func</code> emits debugging information to denote function <var>name</var>, and
is ignored unless the file is assembled with debugging enabled.
Only ‘<samp><span class="samp">--gstabs[+]</span></samp>’ is currently supported.
<var>label</var> is the entry point of the function and if omitted <var>name</var>
prepended with the ‘<samp><span class="samp">leading char</span></samp>’ is used.
‘<samp><span class="samp">leading char</span></samp>’ is usually <code>_</code> or nothing, depending on the target.
All functions are currently defined to have <code>void</code> return type.
The function must be terminated with <code>.endfunc</code>.
