出现现场：int64_t mNumPacketsReceived;ALOGV("Line %lld: %.2f %.2f %.2f, slope %.2f", mNumPacketsReceived, n1, n2, b, -n1 / n2);解决方式：ALOGV("Line %lld: %.2f %.2f %.2f, slope %.2f", (long long) mNumPacketsReceived, n1, n2, b, -n1

在使用CLang编译C++源码时出现这种警告，原因是switch-case代码段里没有加break，例如下面这样：switch (count) { case 3: data[offset++] = 0; case 2: data[offset++] = 0; case 1: data[offset++] = 0;}但是有时候自己的代码逻辑上就是要不加break，那需要怎么解决这个警告？解决方式：#define FALLTHROUGH_INTENDED [[fa
