 /* For SVR4 shared libraries, each call to a library routine goes through
-   a small piece of trampoline code in the ".init" section.  Although each
-   of these fragments is labeled with the name of the routine being called,
-   the gdb symbol reading code deliberately ignores them so it won't confuse
-   them with the real functions.  It does however know about the label that
-   precedes all of the fragments, which is "_init".  Thus when we lookup a
-   function that corresponds to a PC value which is in one of the trampoline
-   fragments, we'll appear to be in the function "_init".  The following
-   macro will evaluate to nonzero when NAME is valid and matches "_init".
+   a small piece of trampoline code in the ".plt" section.
    The horribly ugly wait_for_inferior() routine uses this macro to detect
    when we have stepped into one of these fragments. */
