Quick question
by Ben.Young＠risk.sungard.com April 14, 2005

April 14, 2005

Just a quick question from an interested observer! Has the trivial object space completely died now? I can't find in the source, but the documentation specifically states that it won't be going away! Keep up the good work! Cheers, Ben

I changed the flow space to unify calls to built-in functions and operations when possible. For example, the annotator had to deal with both the 'type' operation and the 'type()' built-in doing the same thing. Now the flow objspace contains a … [View More]

Integer arithmetic
by Armin Rigo April 12, 2005

April 12, 2005

Hi all, (IRC summary with Samuele and myself) We propose the following rules for how integer operations should behave in R-Python code: * operations on plain integers produce longs in CPython when they overflow, and wrap-around silently on platforms like C. In other words, they behave differently when run on top of Python or after translation. We cannot easily change that, but instead the following rule seems to be the sanest idea: in both cases, the only guarantee is that the last 32 (or … [View More]

With the current PyPy HEAD, help(1) results in OverflowError, after a long time. I just wanted to test whether pydoc works, but I didn't expect OverflowError...

There is already code in simplify.py that should remove empty blocks and perform other similar simplifications. I guess it needs to be called again after the annotator's "a.simplify()", which might remove some operations and thus make new blocks empty. Armin
