- * to clean up support for bizarre-endian architectures.
- *
- * Trent Piepho <xyzzy@speakeasy.org> 2007114

- * ___swabXX
- * Generic C versions of the swab functions.
- *
- * ___constant_swabXX
- * C versions that gcc can fold into a compile-time constant when
- * the argument is a compile-time constant.
- *
- * __arch__swabXX[sp]?
- * Architecture optimized versions of all the swab functions
- * (including the s and p versions). These can be defined in
- * asm-arch/byteorder.h. Any which are not, are defined here.
- * __arch__swabXXs() is defined in terms of __arch__swabXXp(), which
- * is defined in terms of __arch__swabXX(), which is in turn defined
- * in terms of ___swabXX(x).
- * These must be macros. They may be unsafe for arguments with
- * side-effects.
- *
- * __fswabXX
- * Inline function versions of the __arch__ macros. These _are_ safe
- * if the arguments have side-effects. Note there are no s and p
- * versions of these.
- *
- * __swabXX[sb]
- * There are the ones you should actually use. The __swabXX versions
- * will be a constant given a constant argument and use the arch
- * specific code (if any) for non-constant arguments. The s and p
- * versions always use the arch specific code (constant folding
- * doesn't apply). They are safe to use with arguments with
