There are PowerPC instructions to load and store 16 and 32 bit little-endian integers ... I suspect the swap routine you mention uses one of those instructions. I haven't heard of it -- I grepped through /System/Library/Frameworks and didn't find it.

Can you point me to the documentation for it?

32bit word

lwbrx -load word byte reversed indexed
stwbrx - store word byte reversed indexed

16 bit word
lhbrx - load half word byte reversed indexed
sthbrx - store half world byte reversed indexed
