[Bug java/18190] New: [4.0 regression] primitive array optimization is gone

["tromey at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

Sample source:

public class t
{
  public static final int[] x = { 5, 7, 9, 11 };
}

In gcc 3.3 (and 3.4 and earlier than 3.3), this code compiled
to something like:

.LJv0.0:
	.long	_Jv_intVTable
	.long	4
	.long	5
	.long	7
	.long	9
	.long	11

Now we actually emit code for this.

The culprits are a combination of this patch to gcj:

2004-07-08  Richard Henderson  <rth@redhat.com>

	* expr.c (case_identity, get_primitive_array_vtable,
	java_expand_expr, emit_init_test_initialization): Remove.
	* java-tree.h (java_expand_expr): Remove.
	* lang.c (LANG_HOOKS_EXPAND_EXPR): Remove.

and this patch to libgcj (which removed the primitive vtables):

2004-07-23  Bryce McKinlay  <mckinlay@redhat.com>

	* prims.cc (_Jv_InitPrimClass): Don't create an array class.
	(_Jv_CreateJavaVM): Don't pass array vtable parameter to
	_Jv_InitPrimClass.
	(DECLARE_PRIM_TYPE): Don't declare array vtables.
	* include/jvm.h (struct _Jv_ArrayVTable): Removed.
	* java/lang/Class.h (_Jv_InitPrimClass): Update friend declaration.
