<h3 class="section">2.6 Nested Procedures</h3>
|
|
|
|
<p>For any of the symbol descriptors representing procedures, after the
|
|
symbol descriptor and the type information is optionally a scope
|
|
specifier. This consists of a comma, the name of the procedure, another
|
|
comma, and the name of the enclosing procedure. The first name is local
|
|
to the scope specified, and seems to be redundant with the name of the
|
|
symbol (before the ‘<samp>:</samp>’). This feature is used by GCC, and
|
|
presumably Pascal, Modula-2, etc., compilers, for nested functions.
|
|
</p>
|
|
<p>If procedures are nested more than one level deep, only the immediately
|
|
containing scope is specified. For example, this code:
|
|
</p>
|
|
<div class="example">
|
|
<pre class="example">int
|
|
foo (int x)
|
|
{
|
|
int bar (int y)
|
|
{
|
|
int baz (int z)
|
|
{
|
|
return x + y + z;
|
|
}
|
|
return baz (x + 2 * y);
|
|
}
|
|
return x + bar (3 * x);
|
|
}
|
|
</pre></div>
|
|
|
|
<p>produces the stabs:
|
|
</p>
|
|
<div class="example">
|
|
<pre class="example">.stabs "baz:f1,baz,bar",36,0,0,_baz.15 # <span class="roman">36 is N_FUN</span>
|
|
.stabs "bar:f1,bar,foo",36,0,0,_bar.12
|
|
.stabs "foo:F1",36,0,0,_foo
|
|
</pre></div>
