| <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> |
