- * It is also used to handle items on the stack in store opcodes, since it is
- * possible that the variable to be stored into is already on the stack, in
- * which case its old value should be used.
- * A single joint point will use the same variables (stored in the array bb->out_stack or
- * bb->in_stack, if the basic block is before or after the joint point).
- * If the stack merge fails at a join point, cfg->unverifiable is set.
