Comment (by sebastian.huber):
I think nobody needs FP code in ISRs, but sometimes a compiler/library
plagues you with some FP code in unexpected situations. Option (2) is the
only one I would not choose. On SPARC I tend to implement (1). On
PowerPC for the FPU and AltiVec I tend to use (3). The problem with (3)
is that it works silently in the background and you may only notice
changes if you get strange timing problems (hard to test in a test suite)
after a GCC update for example.
