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. iPÃi(uclocku1.1iicBs/|EeZdddddd„Zd„ZdS(icCs1||_||_||_||_||_dS(N(uPtrCompuDiscruEnumCompuIntCompu StringComp(uselfuPtrCompuDiscruEnumCompuIntCompu StringComp((u)/mit/python/lib/python3.0/test/pystone.pyu__init__-s     cCs%t|j|j|j|j|jƒS(N(uRecorduPtrCompuDiscruEnumCompuIntCompu StringComp(uself((u)/mit/python/lib/python3.0/test/pystone.pyucopy5sN(u__name__u __module__uNoneu__init__ucopy(u __locals__((u)/mit/python/lib/python3.0/test/pystone.pyuRecord+s  uRecordcCs;t|ƒ\}}tdt||fƒtd|ƒdS(Nu#Pystone(%s) time for %d passes = %gu-This machine benchmarks at %g pystones/second(upystonesuprintu __version__(uloopsu benchtimeustones((u)/mit/python/lib/python3.0/test/pystone.pyumain<scCs t|ƒS(N(uProc0(uloops((u)/mit/python/lib/python3.0/test/pystone.pyupystonesCsui3cCs|dd…S(N((ux((u)/mit/python/lib/python3.0/test/pystone.pyuKsc Csötƒ}xt|ƒD]}qWtƒ|}tƒatƒatt_tt_tt_ dt_ dt_ d}dt dd!sT    :
