[jira] [Created] (ARROW-9118) [C++] Add more general BoundsCheck function that also checks for arbitrary lower limits in integer arrays

Wes McKinney created ARROW-9118:
-----------------------------------

             Summary: [C++] Add more general BoundsCheck function that also checks for arbitrary lower limits in integer arrays
                 Key: ARROW-9118
                 URL: https://issues.apache.org/jira/browse/ARROW-9118
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney
            Assignee: Wes McKinney
             Fix For: 1.0.0


See ARROW-9083. The current {{IndexBoundsCheck}} is specialized to skip a comparison for unsigned integers and uses 0 as the lower bound for signed integers. This could be generalized so that we could check e.g. if int64 values will fit in the int32 range
