I agree, in principle. In practice there are some thorny issues to deal with, and things to think about: (1) The method for getting and setting the FPU precision varies from platform to platform (2) Most modern x86 processors have *two* FPUs that might be used (the SSE unit, and the x87), each with their own control words. (3) Depending on the platform and compiler flags, a Python executable / shared library might be using the x87 instructions, the SSE2 instructions, or a mixture of both. (4) We need to bear in mind that an executable created on a modern 32-bit Linux machine (with SSE2) might still need to run on older machines that don't have SSE2. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9980> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
