* expr.c (copy_blkmode_from_reg): Fix operand_subword_force call.

Thu Jun  7 12:12:58 CEST 2001  Jan Hubicka  <jh@suse.cz>

	* toplev.c (rest_of_compilation): Call split_all_insns
	before reg-stack and shorten-branches. Do shorten-branches
	after reg-stack.
	* final.c (shorten_branches): Remove insn splitting code.
