| * Could have been named NUXI-endian, but we use the same name as in glibc. |
| * hopefully only the PDP and its evolutions (old VAXen in compatibility mode) |
| * should ever use this braindead byteorder. |
| * This file *should* work, but has not been tested. |
| * |
| * little-endian is 1234; big-endian is 4321; nuxi/pdp-endian is 3412 |
| * |
| * I thought vaxen were NUXI-endian, but was told they were correct-endian |
| * (little-endian), though indeed there existed NUXI-endian machines |
| * (DEC PDP-11 and old VAXen in compatibility mode). |
| * This makes this file a bit useless, but as a proof-of-concept. |
| * |
| * But what does a __u64 look like: is it 34127856 or 78563412 ??? |
| * I don't dare imagine! Hence, no 64-bit byteorder support yet. |
| * Hopefully, there 64-bit pdp-endian support shouldn't ever be required. |
