/* Note - there are three possible -mfpu= arguments that can be passed to

   the assembler:

     -mfpu=softvfp   This is the default.  It indicates thats doubles are

                     stored in a format compatible with the VFP

                     specification.  This is the newer double format, whereby

                     the endian-ness of the doubles matches the endian-ness

                     of the memory architecture.

     -mfpu=fpa       This is when -mhard-float is specified.

                     [It is not known if any XScale's have been made with

                     hardware floating point support, but nevertheless this

                     is what happens].

     -mfpu=softfpa   This is when -msoft-float is specified.

                     This is the normal behavior of other arm configurations,

                     which for backwards compatibility purposes default to

                     supporting the old FPA format which was always big

                     endian, regardless of the endian-ness of the memory

                     system.  */
