- /* 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".
- The horribly ugly wait_for_inferior() routine uses this macro to detect
- when we have stepped into one of these fragments. */
