            Bug ID: 89845
           Summary: Consider improving division and modulo by constant if
                    highpart multiply is cheap
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal

          Reporter: jakub at gcc dot gnu.org
  Target Milestone: ---

The
https://arxiv.org/pdf/1902.01961.pdf
paper shows some possible improvements for the division and modulo by constant
(and modulo by constant equality comparison against 0).
