In other words, do L1, L2, L3, etc. caches always reflect the endianness of their CPU?
Or does it make more sense to always store data in caches in some specific endianness?
Is there a general de...

I have a special unsigned long (32 bits) and I need to convert the endianness of it bit by bit - my long represents several things all smooshed together into one piece of binary.
How do I do it?
