264 /* True if the given mode has a NaN representation and the treatment of
265    NaN operands is important.  Certain optimizations, such as folding
266    x * 0 into x, are not correct for NaN operands, and are normally
267    disabled for modes with NaNs.  The user can ask for them to be
268    done anyway using the -funsafe-math-optimizations switch.  */
