For PR java/4509:
* parse.y (java_complete_lhs) [COMPOUND_EXPR]: Correctly compute CAN_COMPLETE_NORMALLY for the node. * jcf-write.c (generate_bytecode_insns) [COMPOUND_EXPR]: Don't generate code for second branch if first branch can't complete normally. (generate_bytecode_insns) [LOOP_EXPR]: Don't generate `goto' to the loop head if the loop body can't complete normally. From-SVN: r48249
