That hasn't been the full story for a while. FPA (the obsolete, usually emulated floating point format) does this, but all modern systems use VFP word ordering, even if they have only software floating point. I don't see a single clear macro that determines this. __VFP_FP__ is a subset of the times that normal IEEE layout is used. -- Daniel Jacobowitz CodeSourcery
