* toplev.c (flag_evaluation_order): New global variable. * flags.h (flag_evaluation_order): Prototype here. * expr.c (expand_operands): If we need to preserve observable evaluation order, protect exp1 from clobbering exp0's result. * java/lang.c (java_init_options): Set flag_evaluation_order. * java/expr.c (force_evaluation_order): Don't attempt to force evaluation order of binary operations using save_expr. * java/parse.y (java_complete_lhs): No longer need to call force_evaluation_order when constructing binary operators.
