            Bug ID: 60646
           Summary: Investigate improved complex division algorithms
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jb at gcc dot gnu.org

The paper http://arxiv.org/abs/1210.4539 analyzes several algorithms for
complex division. Currently GFortran IIRC uses the Smith (1962) algorithm. We
should investigate whether GFortran could switch to one of the improved
algorithms without compromising performance too much.
