So, let us conclude that the original author might have though about
it and concluded that only ints would go into the binary (if the
compiler would properly optimize it), so that it wouldn't be a problem.
Let's decide right now that this reasoning is "off limits" and should
be avoided.
If you suspect a compiler bug that has to do with optimizing, you
might want to compile the kernel with less optimization to see if that
fixes the obscure bug that you're seeing. If that introduces new bugs
(due to the fp unit not getting saved/restored) then we're in deep
shit.
Conclusion: Yes, you could use an FP calculation for an integer
constant and get the compiler to convert to integer before creating
the binary. However we don't want to depend on the compiler for
this to happen ALL the time.....
