"PYSTONE" Benchmark Program
|
|
||||||
|
|
||||||
Version: Python/1.2 (corresponds to C/1.1 plus 3 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.
|
|
||||||
|
|
||||||
Version 1.2 changes the division to floor division.
|
|
||||||
|
|
||||||
Under Python 3 version 1.1 would use the normal division
|
|
||||||
operator, resulting in some of the operations mistakenly
|
|
||||||
yielding floats. Version 1.2 instead uses floor division
|
|
||||||
making the benchmark an integer benchmark again.
