I don't know GMP internals.

Oh yes, I removed the cache because I would like to quickly get a working Python version. It took me two weeks to write the patch. It's not easy to get into CPython source code! And integer is one of the most important type! > I can vouch for that. Allocation can easily dominate performance. It > invalidates the rest of the benchmark. I may also use Python garbage collector for GMP memory allocations since GMP allows to use my own memory allocating functions. GMP also has its own reference counter mechanism :-/ Victor -- Victor Stinner aka haypo http://www.haypocalc.com/blog/ _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
