Martin Panter added the comment: Okay, so to be clear, I am assuming XLC supports all of the following fields, and uses unsigned bit fields by default:
struct UNSIGNED_BITS { unsigned int AU: 1; int A: 1; /* Equivalent to unsigned int */ signed int AS: 1; unsigned short MU: 1; short M: 1; /* Equivalent to unsigned short; triggers warning */ }; and that it cannot compile the following: struct SIGNED_BITS { signed short MS: 1; /* Not supported */ }; Attached is what I think a patch to resolve this would look like. However it needs a line in Modules/_ctypes/_ctypes_test.c completed to detect the compiler: #ifndef /* Something to identify XLC */ Can you figure out a way to test for XLC (but not GCC, which the AIX buildbot uses), and then try my patch out? Hopefully you see no more compiler warnings, test_ints() should now pass, and test_shorts() should be skipped. ---------- keywords: +patch Added file: http://bugs.python.org/file44005/disable-signed-short.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27643> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
