What about enabling SPARC_USE_SAFE_FP_SUPPORT also in uniprocessor
configurations and maybe add a lazy floating point safe as an

With this optimization, would it behave like the standard deferred
method, but with the FP context only being saved if the last FP task
was switched out as the result of an interrupt? And similar for
loading the FP context? No need to load it if returning from a call to
rtems_task_wake_after() I guess.
Yes, but this optimization works only in uniprocessor configurations.
