+/* 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.  */
