re PR libgcj/26858 (NullPointerException not generated for large classes...)
2006-03-30 Andrew Haley <aph@redhat.com>
PR java/26858
* lang.c (java_attribute_table): New.
(LANG_HOOKS_ATTRIBUTE_TABLE): Define.
* expr.c (build_field_ref): Add a null pointer check for all
fields of offset > 4k. Don't do so for accesses via the this
pointer, which we know can never be null.
* class.c (build_java_method_type): Mark arg 1 of all nonstatic
methods nonnull.
