Hello,

Is there a reason for using -mfixed-range=f2-f5,f12-f15,f32-f127
when compiling Mini-OS?  Is it really needed since it doesn't
have a user-land? (though I guess some support would be needed in
switch_context for instance)

Then, are there other reasons for using __*div/di*.S instead of just
linking with libgcc?

Samuel
