* hppah-tdep.c (frame_saved_pc): Use better test for outermost
frame. Use find_return_regnum to find the caller.
* (find_unwind_entry): New routine to locate stack frame info
associated with a procedure. This looks in the $UNWIND_START$
section in the SOM file.
* (find_return_regnum): New routine. Uses find_unwind_entry() to
figure out where the caller's return address is stored.
* (find_proc_framesize): New routine. Uses find_unwind_entry()
to figure out the frame size for a procedure.
* (saved_pc_after_call): New routine, moved from tm-hppa.h.
* (init_extra_frame_info): New routine. Corrects PC and FP for
outermost frame if necessary.
* (frame_chain): New routine, moved from tm-hppa.h.
* (skip_trampoline_code): Handle computed function calls (ie:
calls from $$dyncall).
* (unwind_command): Temporary support function to allow user
to control/observe aspects of the unwind (stack frame) info.
* infcmd.c (read_pc): (Temporary), put a hack in to see if the PC
was in a system call, if so, then read the PC from r31.
* tm-hppah.h (SKIP_TRAMPOLINE_CODE, IN_SOLIB_TRAMPOLINE): Deal
with extra arg for skip_trampoline_code().
* (INIT_EXTRA_FRAME_INFO): Define to point at subr (see above).
* (FRAME_CHAIN, FRAME_CHAIN_VALID): Turn into real subroutines.
* tm-hppa.h (SAVED_PC_AFTER_CALL): Turn into real subroutine.
