c-common.h (DECL_NUM_STMTS): New macro.

	* c-common.h (DECL_NUM_STMTS): New macro.
	* c-decl.c (duplicate_decls): Copy DECL_NUM_STMTS, not
	DECL_FRAME_SIZE.
	(pushdecl): Likewise.
	* c-semantics.c (add_stmt): Update DECL_NUM_STMTS.
	* integrate.c (expand_inline_function): Don't check
	DECL_FRAME_SIZE.
	* print-tree.c (print_node): Don't print it.
	* toplev.c (rest_of_compilation): Don't try to inline when
	flag_no_inline is on.
	* tree.h (DECL_FRAME_SIZE): Remove.
	(tree_decl): Adjust accordingly.

	* Makefile.in (optimize.o): Depend on params.h.
	(duplicate_decls): Copy DECL_NUM_STMTS, not DECL_FRAME_SIZE.
	(init_decl_processing): Set flag_no_inline when doing
	inlining-on-trees.
	* optimize.c: Include params.h.
	(struct inline_data): Improve documentation of FNS.  Add
	FIRST_INLINED_FN, INLINED_STMTS, and CLONING_P.
	(INSNS_PER_STMT): New macro.
	(remap_block): Use CLONING_P.
	(inlinable_function_p): Don't inline big functions.
	(expand_call_inline): Keep track of how much inlining we've done.
	(optimize_function): Set FIRST_INLINED_FN.
	(maybe_clone_body): Set CLONING_P.
	* semantics.c (simplify_aggr_init_exprs_r): Fix typing problems in
	tree nodes.
	(genrtl_finish_function): Clear DECL_DEFER_OUTPUT before calling
	rest_of_compilation.  Clear DECL_RTL for local variables
	afterwards.
	(clear_decl_rtl): New function.

	* com.c (duplicate_decls): Don't copy DECL_FRAME_SIZE.

	* parse.h (DECL_END_SOURCE_LINE): Don't rely on DECL_FRAME_SIZE.
