New inline + method get_finalizer(). + (struct _Jv_ArrayVTable): Ditto. Declare method array with + NUM_OBJECT_METHODS elements instead of NUM_OBJECT_METHODS + 1. + (_Jv_AllocObj): Add new jclass parameter. + (_Jv_AllocArray): Ditto. + (_Jv_BuildGCDescr): New prototype. + * prims.cc (_Jv_AllocObject): Rename parameter `c' to `klass'. Pass + `klass' to _Jv_AllocObj. Don't set the new object's vtable. Use + get_finalizer() instead of direct finalizer vtable offset. + (_Jv_NewObjectArray): Rename parameter `clas' to `klass'. Pass + `klass' to _Jv_AllocArray. Don't set the new array's vtable. + (_Jv_NewPrimArray): Call _Jv_FindArrayClass before _Jv_AllocObj. Pass + `klass' to _Jv_AllocObj.

Mark the classes vtable. + (_Jv_MarkArray): Check that vtable doesn't point to a cleared object. + (GC_DEFAULT_DESCR): New #define. + (_Jv_BuildGCDescr): New function. Use GC_DEFAULT_DESCR, for now. + (_Jv_AllocObj): New parameter `klass'. Use GC_GCJ_MALLOC (). + (_Jv_AllocArray): New parameter `klass'. Allocate with GC_MALLOC and + scan conservativly if size is less than min_heap_addr. Set vtable + pointer of new object before returning. + (_Jv_AllocBytes): Use GC_MALLOC_ATOMIC, not GC_GENERIC_MALLOC. + (_Jv_InitGC): Call GC_init_gcj_malloc(). Don't set up marking and + allocation for obj_kind_x. + * nogc.cc (_Jv_BuildGCDescr): New function.
