31/* Note - there are three possible -mfpu= arguments that can be passed to
32   the assembler:
33
34     -mfpu=softvfp   This is the default.  It indicates thats doubles are
35                     stored in a format compatible with the VFP
36		     specification.  This is the newer double format, whereby
37		     the endian-ness of the doubles matches the endian-ness
38		     of the memory architecture.
39
40     -mfpu=fpa       This is when -mhard-float is specified.
41                     [It is not known if any XScale's have been made with
42		     hardware floating point support, but nevertheless this
43		     is what happens].
44
45     -mfpu=softfpa   This is when -msoft-float is specified.
46                     This is the normal behavior of other arm configurations,
47		     which for backwards compatibility purposes default to
48		     supporting the old FPA format which was always big
49		     endian, regardless of the endian-ness of the memory
50		     system.  */
