New Revision: 10588

Added:
   pypy/dist/pypy/translator/test/rpystone.py   (contents, props changed)
Log:
this is an adjusted version of pystone.py,
to be valid for flow space.
It can be run like pystone. Without an argument,
it tries to be quick for PyPy.

Added: pypy/dist/pypy/translator/test/rpystone.py

+"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.
