for consistency.

-// // This file implements the following soft-float comparison routines:
-//
-//   __eqdf2   __gedf2   __unorddf2
-//   __ledf2   __gtdf2
-//   __ltdf2
-//   __nedf2
-//
-// The semantics of the routines grouped in each column are identical, so there
-// is a single implementation for each, and wrappers to provide the other names.
-//
-// The main routines behave as follows:
-//
-//   __ledf2(a,b) returns -1 if a < b
-//                         0 if a == b
-//                         1 if a > b
-//                         1 if either a or b is NaN
-//
-//   __gedf2(a,b) returns -1 if a < b
-//                         0 if a == b
-//                         1 if a > b
-//                        -1 if either a or b is NaN
-//
-//   __unorddf2(a,b) returns 0 if both a and b are numbers
-//                           1 if either a or b is NaN
-//
-// Note that __ledf2( ) and __gedf2( ) are identical except in their handling of
-// NaN values.
