For any of the above symbol descriptors, after the symbol descriptor and
the type information, there is optionally a comma, followed by the name
of the procedure, followed by a comma, followed by a name specifying the
scope. The first name is local to the scope specified. I assume then
that the name of the symbol (before the @samp{:}), if specified, is some
sort of global name. I assume the name specifying the scope is the name
of a function specifying that scope. This feature is an AIX extension,
and this information is based on the manual; I haven't actually tried
it.
scope. The first name is local to the scope specified, and seems to be
redundant with the name of the symbol (before the @samp{:}). The name
specifying the scope is the name of a procedure specifying that scope.
This feature is used by @sc{gcc}, and presumably Pascal, Modula-2, etc.,
compilers, for nested functions.
If procedures are nested more than one level deep, only the immediately
containing scope is specified, for example:
@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);
@}
@end example

produces the stabs:
@example
.stabs "baz:f1,baz,bar",36,0,0,_baz.15 # 36 == N_FUN
.stabs "bar:f1,bar,foo",36,0,0,_bar.12
.stabs "foo:F1",36,0,0,_foo
@end example
The stab representing a procedure is located immediately following the
code of the procedure. This stab is in turn directly followed by a
