That's wrong from a pypy point of view --- or at least not helpful. Right now, if your stars are correctly aligned and all the ctypes calls use the fast path, then pypy generates a block of assembler containing the direct calls to C code. While not strictly the same performance as a good optimizing compiler, the difference should not be measurable in this case. Not to mention that Cython code linked as a cpyext module for pypy is going to interface very slowly with the rest of pypy. If you need to exchange the gmp values between Python and the gmp library, then Cython looses on pypy. (Stefan, it seems like you are regularly using the pypy list to make the promotion of Cython. While I have nothing against Cython, your knowledge about pypy appears to be superficial. So may I please ask you to stop? Thank you.) A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
