- * linux/byteorder/swabb.h
- * SWAp Bytes Bizarrely
- * swaHHXX[ps]?(foo)
- *
- * Support for obNUXIous pdp-endian and other bizarre architectures.
- * Will Linux ever run on such ancient beasts? if not, this file
- * will be but a programming pearl. Still, it's a reminder that we
- * shouldn't be making too many assumptions when trying to be portable.

-/*
- * Meaning of the names I chose (vaxlinux people feel free to correct them):
- * swahw32 swap 16-bit half-words in a 32-bit word
- * swahb32 swap 8-bit halves of each 16-bit half-word in a 32-bit word
- *
- * No 64-bit support yet. I don't know NUXI conventions for long longs.
- * I guarantee it will be a mess when it's there, though :->
- * It will be even worse if there are conflicting 64-bit conventions.
- * Hopefully, no one ever used 64-bit objects on NUXI machines.
