The values of the segment registers are kept as address ranges.
The segment register does not change its value within one address range. The processor module finds segment register change points and splits sreg_range_t ranges so that a new sreg_range_t range is started at each segment register change point. The kernel deletes sreg_range_t if an instruction is converted back to unexplored bytes.
So, we have information about a segment register by keeping information about the range of addresses where segment register does not change the value.
Note that each segment has information about the default values of the segment registers. This information is used if the value of a segment register could not be determined.
