STINNER Victor added the comment: If you compile Python with GCC, we can maybe try something with __attribute__ ((aligned (sizeof(void *)))) attribute. The attribute can be used on a structure field. The problem is that we don't care of the alignment of header attributes, only of data, but data is not a field but the data just after the structure.
Or is it possible to GCC to get a structure size aligned on 4 bytes? For the explicit padding: how do you compute the size of the padding? How about disabling the fast-path in FASTSEARCH if data is not aligned? (You might get non-aligned if even if structure is correctly aligned, it may happen if the memory allocator does not align memory blocks. I don't know if Python may get "unaligned" memory blocks.) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19537> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
