Other benefits of software (e.g. compiler) level occupation of the
optimization space - lower energy usage (compiler pre-calculation of
the optimizations which the hardware otherwise has to just guess at)
and less complexity of hardware (again, either lower energy usage, or
transistors which can be put to other functions).
