| "PYSTONE" Benchmark Program
 | |
| 
 | |
| Version:        Python/1.1 (corresponds to C/1.1 plus 2 Pystone fixes)
 | |
| 
 | |
| Author:         Reinhold P. Weicker,  CACM Vol 27, No 10, 10/84 pg. 1013.
 | |
| 
 | |
|                 Translated from ADA to C by Rick Richardson.
 | |
|                 Every method to preserve ADA-likeness has been used,
 | |
|                 at the expense of C-ness.
 | |
| 
 | |
|                 Translated from C to Python by Guido van Rossum.
 | |
| 
 | |
| Version History:
 | |
| 
 | |
|                 Version 1.1 corrects two bugs in version 1.0:
 | |
| 
 | |
|                 First, it leaked memory: in Proc1(), NextRecord ends
 | |
|                 up having a pointer to itself.  I have corrected this
 | |
|                 by zapping NextRecord.PtrComp at the end of Proc1().
 | |
| 
 | |
|                 Second, Proc3() used the operator != to compare a
 | |
|                 record to None.  This is rather inefficient and not
 | |
|                 true to the intention of the original benchmark (where
 | |
|                 a pointer comparison to None is intended; the !=
 | |
|                 operator attempts to find a method __cmp__ to do value
 | |
|                 comparison of the record).  Version 1.1 runs 5-10
 | |
|                 percent faster than version 1.0, so benchmark figures
 | |
|                 of different versions can't be compared directly.
