STINNER Victor added the comment: "Relying on things like int64_t or uint64_t is tricky, both in principle *and* in practice. (...) uint64_t and int64_t may be a stretch, particularly on ARM-style platforms."
I don't understand. Python is already using 64-bit types, in md5 module for example (MD5_INT64). This module is not compiled on ARM? "In practice, we've had significant difficulties in the past simply finding and identifying exact-width types in our autoconf machinery: whether they're defined in <inttypes.h> or <stdint.h> seems to vary from platform to platform, as does whether they're defined as typedef's or preprocessor macros." I don't understand. AC_TYPE_UINT64_T is supposed to provide the uint64_t (unsigned integer of 64-bit). Autotool can also generate the stdint.h header if it is not available. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17884> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
