The code LGTM.

For practical applications, we sometimes use 3-way function splitting resulting in code being broken into more than two partitions. In such case, the most interesting metrics and score should be attached to non-cold partitions. With "hot text" enabled, the corresponding address range of such partition could be identified by [__hot_start, __hot_end).
