Because lots of people were fighting it and I am therefore still collecting data points to justify the alignment change. That's why I created the WIP wiki page. I will add more information to this page. One important data point is that there was an unintentional ABI breakage on s390x at some point where they still went aheadwith. > > FWIW, NetBSD uses 4 bytes alignment on m68k which means they don't have to > > rely > > on constantly having to patch projects to build with 2 byte alignment. > > Even the sun2 port, which is for the m68010 (an actual machine which might > benefit from a 2 byte alignment) uses 4 byte alignment in NetBSD. Well, the official SysV ELF ABI by AT&T uses 4 byte alignment, so I would expect any *nix flavor which adheres to the official specification to use 4 byte alignment. Adrian -- .''`.
