Variable range analysis is essential for compiler optimization
static analysis and software testing.This paper extends the classical interval abstraction
and defines the new numeric interval-set algebra
Boolean interval algebra and reference interval algebra.Then it presents a unified method of variable range analysis based on abstract interpretation (RABAI).This method uses widening operator to compute variable range in loop
undefined value to describe procedure parameters
and applies function summary as a stand-in for the function.RABAI compresses variable value ranges
and can detect infeasible paths in program.Finally RABAI is applied in Java code analysis tool DTS
and DTS can reduce the false positive rate of bug checking result.
