+// // This file implements the following soft-float comparison routines:
+//
+//   __eqtf2   __getf2   __unordtf2
+//   __letf2   __gttf2
+//   __lttf2
+//   __netf2
+//
+// 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:
+//
+//   __letf2(a,b) returns -1 if a < b
+//                         0 if a == b
+//                         1 if a > b
+//                         1 if either a or b is NaN
+//
+//   __getf2(a,b) returns -1 if a < b
+//                         0 if a == b
+//                         1 if a > b
+//                        -1 if either a or b is NaN
+//
+//   __unordtf2(a,b) returns 0 if both a and b are numbers
+//                           1 if either a or b is NaN
+//
+// Note that __letf2( ) and __getf2( ) are identical except in their handling of
+// NaN values.
