	* Makefile.in (OBJS): Remove stupid.o.
	(stupid.o): Likewise.

	* except.c (emit_eh_context): Don't emit USEs for stupid.
	* explow.c (probe_stack_range): Likewise.
	* flags.h (obey_regdecls): Remove.
	* flow.c (find_basic_blocks): Don't run try_merge_blocks

	(life_analysis): Limit data collection when not optimizing.
	(mark_regs_live_at_end): Always mark the return value registers.
	(mark_used_regs): Remove dummy RETURN case.
	(print_rtl_with_bb): Don't consult obey_regdecls.
	* function.c (use_variable, use_variable_after): Remove.
	(assign_parms): Consult optimize not obey_regdecls.
	(expand_function_start): Don't emit USEs for stupid.
	(expand_function_end): Likewise.
	* global.c (build_insn_chain): Export.
	* integrate.c (expand_inline_function): Kill return-value USE
	handling code.
	* jump.c (jump_optimize_1): Do simple jump optimizations and
	dead code elimination.
	(calculate_can_reach_end): Remove check_deleted argument.
	(delete_insn): Patch out insns even when not optimizing.
	* local-alloc.c (block_alloc): Don't do tying when not optimizing.

	(build_insn_chain): Declare.
	* stmt.c (expand_value_return): Don't emit USEs for stupid.
	(expand_end_bindings): Likewise.
	(expand_decl): Likewise.  Consult optimize not obey_regdecls.
	* toplev.c (obey_regdecls): Remove.
	(rest_of_compilation): Don't set it.  Kill stupid in favour of
