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. - -""" - -LOOPS = 50000 - -from time import time - -__version__ = "1.2" - -[Ident1, Ident2, Ident3, Ident4, Ident5] = range(1, 6) -
