    runtime: add arm soft division and modulo benchmarks · d1537809
    Dave Cheney authored
    arm soft div and mod performance plays an important part
    in runtime performance.
    
    The currently implementation is very stable, but we believe
    we can best it. This benchmark provides a reference point.
