Value range analysis

In computing, in particular compiler construction, value range analysis is a type of data flow analysis that tracks the range (interval) of values that a numeric variable can take on at each point of a program's execution. The resulting information can be used in optimizations such as redundancy elimination, dead code elimination, instruction selection…
