/* Dynamic function trampolines are similar to solib trampolines in that they
are between the caller and the callee. The difference is that when you
enter a dynamic trampoline, you can't determine the callee's address. Some
(usually complex) code needs to run in the dynamic trampoline to figure out
the callee's address. This macro is usually called twice. First, when we
enter the trampoline (looks like a normal function call at that point). It
should return the PC of a point within the trampoline where the callee's
address is known. Second, when we hit the breakpoint, this routine returns
the callee's address. At that point, things proceed as per a step resume
breakpoint. */
