* Patches from Jeffrey Law <law@cs.utah.edu>.
* gdb/hppa-tdep.c: Declare frame_saved_pc.
(frameless_function_invocation): New function.
(frame_saved_pc, init_extra_frame_info): Use
frameless_function_invocation.
* gdb/config/tm-hppa.h (SAVED_PC_AFTER_CALL): Use saved_pc_after
call instead of just grabbing the value currently in %r2.
(FRAMELESS_FUNCTION_INVOCATION): Use frameless_function_invocation.
* gdb/config/tm-hppah.h (SAVED_PC_AFTER_CALL): Delete private
definition and use the common one in tm-hppa.h.
