Convert frame unwinders to use the current frame and
"struct value". * frame.c (frame_debug): Make global. (get_frame_id): Pass this frame to unwinder routines. (frame_pc_unwind): Remove unused unwind->prev_pc support. (do_frame_register_read): Do not discard the return value of frame_register_read. (frame_register_unwind): Remove debug messages. Use frame_unwind_register_value. (frame_unwind_register_value, get_frame_register_value): New functions. (create_new_frame, get_frame_base_address, get_frame_locals_address) (get_frame_args_address, get_frame_type): Pass this frame to unwinder routines. (frame_cleanup_after_sniffer, frame_prepare_for_sniffer): New functions. * frame.h: Update comments. (frame_debug, frame_unwind_register_value, get_frame_register_value) (frame_prepare_for_sniffer): Declare. * frame-unwind.h: Update comments and parameter names. (default_frame_sniffer): Declare. (frame_prev_register_ftype): Return a struct value *. (struct frame_unwind): Remove prev_pc member. (frame_unwind_sniffer_ftype, frame_unwind_append_sniffer): Delete. (frame_unwind_append_unwinder, frame_unwind_got_optimized) (frame_unwind_got_register, frame_unwind_got_memory) (frame_unwind_got_constant, frame_unwind_got_address): Declare. * frame-base.h: Update comments and parameter names. * valops.c (value_fetch_lazy): Use get_frame_register_value. Iterate if necessary. Add debugging output. * sentinel-frame.c (sentinel_frame_prev_register) (sentinel_frame_this_id): Update for new signature. (sentinel_frame_prev_pc): Delete. (sentinel_frame_unwinder): Remove prev_pc. * ia64-tdep.c (ia64_libunwind_frame_unwind): Do not initialize prev_pc. * libunwind-frame.c (libunwind_frame_unwind): Likewise. * frame-unwind.c (struct frame_unwind_table_entry): Remove sniffer. (frame_unwind_append_sniffer): Delete. (frame_unwind_append_unwinder): New function. (frame_unwind_find_by_frame): Take this frame. Only use sniffers from unwinders. Use frame_prepare_for_sniffer. (default_frame_sniffer, frame_unwind_got_optimized) (frame_unwind_got_register, frame_unwind_got_memory) (frame_unwind_got_constant, frame_unwind_got_address): New functions. * dummy-frame.c (dummy_frame_sniffer): Use gdbarch_dummy_id. (dummy_frame_prev_register, dummy_frame_this_id): Update for new signature. * gdbarch.sh: Replace unwind_dummy_id with dummy_id. * gdbarch.c, gdbarch.c: Regenerated. * frame-base.c (default_frame_base_address) (default_frame_locals_address, default_frame_args_address): Update for new signature. (frame_base_find_by_frame): Pass this frame to unwinder routines. * infcall.c (call_function_by_hand): Update comments. * Makefile.in (frame-unwind.o): Update dependencies. * gdbint.texinfo (Stack Frames): New chapter. (Algorithms): Move Frames text to the new chapter. (Target Conditionals): Delete SAVE_DUMMY_FRAME_TOS. Document gdbarch_dummy_id instead of gdbarch_unwind_dummy_id.
