class.c (emit_register_classes): Use assemble_jcr if possible.
2001-08-08 Anthony Green <green@redhat.com>
* java/class.c (emit_register_classes): Use assemble_jcr if
possible. Keep the original mechanism as a fallback.
* defaults.h (JCR_SECTION_NAME): Define if we have named section
and weak symbol support.
* crtstuff.c (__JCR_LIST__): Define.
(__JCR_END__): Define.
(_Jv_RegiserClasses): Define weak symbol if possible.
(__do_global_ctors_aux): Register classes for ELF targets with
weak symbol support.
