[tree-ssa] bnw-simple merge PATCH

[Jason Merrill]

I'm checking in the initial merge of the bnw-simple code.  More cleanup
will follow.  Let the carnage begin.

2002-09-24  Jason Merrill  <jason@redhat.com>

	* c-decl.c (poplevel): Only add undeclared labels to the toplevel
	block.
	* c-parse.in (label_decl): Push the declared label.

	* c-decl.c (c_expand_body): If we've been simplified, use
	expand_expr_stmt_value instead.

	* c-decl.c (c_expand_decl): Rename from c_expand_decl_stmt.
	Handle all C-specific expansion semantics.
	* c-tree.h: Change prototype.

	* c-semantics.c (lang_expand_decl_stmt): Remove.
	(genrtl_decl_stmt): Use lang_hooks.expand_decl.
	* Makefile.in (c-semantics.o): Depend on langhooks.h.

	* expr.c (expand_expr) [LOOP_EXPR]: Pass exit_flag==0 to 
	exand_start_loop.
	[BIND_EXPR]: Adjust for functions-as-trees mode.
	[COMPOUND_EXPR]: Avoid recursion if possible.

	* tree.c (build1): Always set TREE_SIDE_EFFECTS for 's' codes.

	* tree.h (enum tree_index): Add TI_EMPTY_STMT.
	(empty_stmt_node): New macro.
	* tree.c (build_common_tree_nodes_2): Initialize it.

	* tree.def: Change some codes from 'e' to 's'.
	(CASE_LABEL_EXPR, ASM_EXPR): New codes.

	* tree.def (SWITCH_EXPR): Now has three operands.

	* tree-inline.c: Retarget to generic trees.  FIXME FIXME.
	* old-tree-inline.c: Old C/Java-specific inliner.
	* Makefile.in (old-tree-inline.o): New rule.
	* c-common.c (c_walk_subtrees): New fn.
	(c_tree_chain_matters_p): New fn.
	* c-lang.c: Use them for LANG_HOOKS_TREE_INLINING_WALK_SUBTREES
	and LANG_HOOKS_TREE_INLINING_TREE_CHAIN_MATTERS_P.
	* c-common.h: Declare them.
	(DECL_NUM_STMTS): Move to tree.h.
	* c-decl.c (finish_function): Simplify the function trees.
	* c-objc-common.c (inline_forbidden_p): Look inside BIND_EXPRs
	for nested functions.  Don't inline a function with _STMT trees.

	* basic-block.h: Include hard-reg-set.h.

	* c-decl.c (start_function): Don't call make_decl_rtl.
	(c_expand_body): Call it here instead.

	* Makefile.in (explow.o): Depend on langhooks.h.

	* unroll.c (copy_loop_body): Don't copy NOTE_INSN_DELETED_LABELs
	between copy_notes_from and loop_end, either.
