* dwarf2-frame.c (dwarf2_frame_cache, dwarf2_frame_this_id)

Browse Source 
(dwarf2_frame_sniffer): Update.
	(dwarf2_signal_frame_this_id): New function.
	(dwarf2_signal_frame_unwind): Use it.
	(dwarf2_frame_base_sniffer): Use frame_unwind_address_in_block.
	* frame.c (frame_func_unwind): Add this_type argument.
	(get_frame_func): Update.
	(frame_unwind_address_in_block): Add this_type argument and check it.
	Fix a typo.
	(get_frame_address_in_block): Update.
	* frame.h (enum frame_type): Move higher in the file.
	(frame_unwind_address_in_block, frame_func_unwind): Add enum frame_type
	argument.

	xstormy16-tdep.c, xtensa-tdep.c: Update calls to
	frame_func_unwind and frame_unwind_address_in_block to specify
	the frame type.  Use frame_unwind_address_in_block instead of
	frame_pc_unwind in sniffers.

	* gdb.arch/i386-signal.c, gdb.arch/i386-signal.exp: New files.
