Ok with changes:

You forgot to prototype this, but we'd be doing less work if

> +      for ( t = registered_class; t; t = TREE_CHAIN (t))
> +	assemble_jcr (XEXP (DECL_RTL (t), 0), 0);

was written as

	named_section_flags (JCR_SECTION_NAME, SECTION_WRITE,
			     POINTER_SIZE / BITS_PER_UNIT);
	for (t = registered_class; t; t = TREE_CHAIN (t))
	  assemble_integer (XEXP (DECL_RTL (t), 0),
			    POINTER_SIZE / BITS_PER_UNIT, 1);
