函数原型：static void add_info(struct gcov_node *node, struct gcov_info *info)

返回类型：void

参数：

类型参数名称
struct gcov_node *node
struct gcov_info *info
617  num等于num_loaded
624  loaded_info等于分配数组内存并置零
625  如果非loaded_info则
626  打印警告信息("could not add '%s' (out of memory)\n", Interface to access gcov_info data )
628  返回
630  内存复制(loaded_info, loaded_info, num * *的长度)
632  loaded_info[num]等于info
634  如果num恒等于0则
639  如果非gcov_info_is_compatible(unloaded_info, info)则
640  打印警告信息("discarding saved data for %s (incompatible version)\n", Interface to access gcov_info data )
643  gcov_info_free(unloaded_info)
644  unloaded_info = NULL
646  否则
651  如果非gcov_info_is_compatible(loaded_info[0], info)则
652  打印警告信息("could not add '%s' (incompatible version)\n", Interface to access gcov_info data )
654  kfree(loaded_info)
655  返回
659  kfree(loaded_info)
660  loaded_info等于loaded_info
661  num_loaded等于num加1
