  Log Message:
  -----------
  Add support for options -frounding-math, ftrapping-math, -ffp-model=, and -ffp-exception-behavior=

    Add options to control floating point behavior: trapping and
    exception behavior, rounding, and control of optimizations that affect
    floating point calculations. More details in UsersManual.rst.
