* 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.
