...m processors in big-endian mode, but it shouldn't be too hard to conditionalize it. If it does turn out to be difficult for some reason, we should at least have comments to indicate where the endian assumptions are being made. AFAICR, people used to use big-endian on non-NEON ARM cores in the 7TDMI/920 days, and if they still do so, they'll buy those chips. IMO, throwing a few comments would be enough for now. It's better to assume little enndian now, with a test case, than to assume big-endian is possible, without one. -- cheers, --renato http://systemcall.org/
