* sentinel-frame.h, sentinel-frame.c: New files. * Makefile.in (frame.o): Update dependencies. (SFILES): Add sentinel-frame.c. (sentinel_frame_h): Define. (COMMON_OBS): Add sentinel-frame.o. (sentinel-frame.o): Specify dependencies. * frame.c: Include "sentinel-frame.h". (frame_register_unwind): Rewrite assuming that there is always a a ->next frame. (frame_register, generic_unwind_get_saved_register): Ditto. (frame_read_unsigned_register, frame_read_signed_register): Ditto. (create_sentinel_frame, unwind_to_current_frame): New functions. (get_current_frame): Rewrite using create_sentinel_frame and unwind_to_current_frame. When possible, always create a frame. (create_new_frame): Set next to the sentinel frame. (get_next_frame): Rewrite. Don't go below the level 0 frame. (deprecated_update_frame_pc_hack): Update the next frame's PC and ID cache when necessary. (frame_saved_regs_id_unwind): Use frame_relative_level. (deprecated_generic_get_saved_register): Use frame_relative_level, get_frame_saved_regs, get_frame_pc, get_frame_base and get_next_frame. (frame_saved_regs_register_unwind): Use get_frame_saved_regs and frame_register.
