	* binutils-all/arm/thumb2-cond.s: Use instructions instead of
	.short.

	gas/
	* config/obj-elf.c (obj_elf_ident): Notify section change to the hook.
	* config/tc-arm.c (make_mapping_symbol): New function, from
	mapping_state.  Save mapping symbols in the frag.
	(insert_data_mapping_symbol): New.
	(mapping_state): Use make_mapping_symbol, improve state transitions.
	(mapping_state_2): New.  Provide dummy definition.
	(opcode_select): Do not call mapping_state.
	(s_bss): Call md_elf_section_change_hook instead of mapping_state.
	(output_inst): Update use of tc_frag_data.
	(new_automatic_it_block): Call mapping_state before emitting the
	IT instruction.
	(md_assemble): Move mapping_state to just before outputting the
	new instruction.
	(arm_handle_align): Update use of tc_frag_data.
	Call insert_data_mapping_symbol.
	(arm_init_frag): Update use of tc_frag_data.  Call
	mapping_state_2.
	(arm_elf_change_section): Always update the mapping symbol FSM state.
	(check_mapping_symbols): New function.
	(arm_adjust_symtab): Use check_mapping_symbols.
	* config/tc-arm.h (struct arm_frag_type): New.
	(TC_FRAG_TYPE): Change to struct arm_frag_type.
	(TC_FRAG_INIT): Pass max_chars.
	(arm_init_frag): Update prototype.
