/* Does the PC fall in a dummy frame?
This function is used by "frame.c" when creating a new `struct
frame_info'.
Note that there is also very similar code in breakpoint.c (where
the bpstat stop reason is computed). It is looking for a PC
falling on a dummy_frame breakpoint. Perhaphs this, and that code
should be combined?
Architecture dependant code, that has access to a frame, should not
use this function. Instead (get_frame_type() == DUMMY_FRAME)
should be used.
Hmm, but what about threads? When the dummy-frame code tries to
relocate a dummy frame's saved registers it definitly needs to
differentiate between threads (otherwize it will do things like
clean-up the wrong threads frames). However, when just trying to
identify a dummy-frame that shouldn't matter. The wost that can
happen is that a thread is marked as sitting in a dummy frame when,
in reality, its corrupted its stack, to the point that a PC is
pointing into a dummy frame. */
