Segev Finer added the comment: We are getting those warnings because distutils builds extension modules without /GL (https://msdn.microsoft.com/en-us/library/0zza0de8.aspx) but with /LTCG (https://msdn.microsoft.com/en-us/library/xbf3tbeh.aspx). We should either add /GL to truly enable whole program optimizations/link-time code generation or remove it.
It is added in https://github.com/python/cpython/blob/896145d9d266ee2758cfcd7691238cbc1f9e1ab8/Lib/distutils/_msvccompiler.py#L233-L241. ---------- nosy: +Segev Finer type: -> behavior versions: +Python 3.5, Python 3.6, Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27790> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
