	* Makefile.in (OBJS): Add rtlhash.o
	* dwarf2out.c (addr_table_entry_do_hash): Convert to inchash.
	(loc_checksum): Dito.
	(loc_checksum_ordered): Dito.
	(hash_loc_operands): Dito.
	(hash_locs): Dito.
	(hash_loc_list): Dito.
	* rtl.c (iterative_hash_rtx): Moved to rtlhash.c
	* rtl.h (iterative_hash_rtx): Moved to rtlhash.h
	* rtlhash.c: New file.
	* rtlhash.h: New file.
