函数名称：gcov_info_is_compatible - check if profiling data can be added*@info1: first profiling data set*@info2: second profiling data set* Returns non-zero if profiling data can be added, zero otherwise.

函数原型：int gcov_info_is_compatible(struct gcov_info *info1, struct gcov_info *info2)

返回类型：int

参数：

类型参数名称
