1. C4x has its own float format so it might actually be valid to do
these transformations.
-ffast-math actually implies behavior change pretty much regardless
of the
floating point unit in use, because it is "screwing" with quite a lot
algebraic
transformations, which don't depend on the usual (and unusual for
that matter)
peculiarities of FP representations.
