The documentation of -ffinite-math-only states
"This option should never be turned on by any '-O' option"
but for sh's -mieee it is said "the default is set to -ffinite-math-only"
(-mieee is unset by default)
as a result the -ffinite-math-only is turned on by default for the sh for all
optimisation levels.
on chapter 2 it was reenforced that: ... "*By default*, it (gcc) will act as
the compiler for a hosted implementation" ... and a conforming hosted
implementation
supports the whole standard.
So either the documentation is false or infinite float values should be
supported (by default).
The ability to perform optimum floating point code is preserved by explicitly
setting it.
