70
71<p>For any of the symbol descriptors representing procedures, after the
72symbol descriptor and the type information is optionally a scope
73specifier.  This consists of a comma, the name of the procedure, another
74comma, and the name of the enclosing procedure.  The first name is local
75to the scope specified, and seems to be redundant with the name of the
76symbol (before the &lsquo;<samp>:</samp>&rsquo;).  This feature is used by GCC, and
77presumably Pascal, Modula-2, etc., compilers, for nested functions.
78</p>
79<p>If procedures are nested more than one level deep, only the immediately
80containing scope is specified.  For example, this code:
81</p>
82<div class="example">
83<pre class="example">int
84foo (int x)
85{
86  int bar (int y)
87    {
88      int baz (int z)
89        {
90          return x + y + z;
91        }
92      return baz (x + 2 * y);
93    }
94  return x + bar (3 * x);
95}
96</pre></div>
97
98<p>produces the stabs:
99</p>
100<div class="example">
101<pre class="example">.stabs &quot;baz:f1,baz,bar&quot;,36,0,0,_baz.15         # <span class="roman">36 is N_FUN</span>
102.stabs &quot;bar:f1,bar,foo&quot;,36,0,0,_bar.12
