    * 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.
