| // // 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. |
