Implement bitmap descriptor based marking for Boehm GC. 2000-09-30 Hans Boehm <boehm@acm.org> Bryce McKinlay <bryce@albatross.co.nz> Implement bitmap descriptor based marking for Boehm GC. * configure.in: Define JC1GCSPEC. Set it if boehm-gc is used. * configure: Rebuilt. * libgcj.spec.in: Pass JC1GCSPEC to jc1. * include/jvm.h (struct _Jv_VTable): New field `gc_descr'. 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. Don't set the new array's vtable. * resolve.cc (METHOD_NOT_THERE, METHOD_INACCESSIBLE): New #defines. (_Jv_ResolvePoolEntry): Use METHOD_NOT_THERE and METHOD_INACCESSIBLE. (_Jv_DetermineVTableIndex): Ditto. (_Jv_PrepareClass): Ditto. Remove offset-by-one adjustments from vtable calculations to account for new gc_descr field. * boehm.cc: #include gc_gcj.h. (obj_kind_x, obj_free_list): `#if 0'-ed away. (_Jv_MarkObj): Check that vtable doesn't point to a cleared object. New commentary from HB. 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. Return 0. (_Jv_AllocObj): Set vtable on returned object. (_Jv_AllocArray): Ditto. * java/lang/Class.h (_Jv_NewObjectArray): No longer a friend. (_Jv_NewPrimArray): Ditto. (_Jv_AllocObj): Declare as a friend. (_Jv_AllocArray): Ditto. * java/lang/natClassLoader.cc (_Jv_FindArrayClass): Copy gc_descr from &ObjectClass into new array class.

# 1. Use "connect" and "accept" to check for -lsocket, and

# 2. Use each function name only once: can't redo a check because

# bogus: they goof up name resolution if used.
# 4. On some SVR4 systems, can't use -lsocket without -lnsl too.
