-// // 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.
