Yes, PPC is also switchable, as is MIPS (my R4000 SGI boxes are big endian, while my R4000 Jazz box (Olivetti M700-10) is little endian). https://en.wikipedia.

Yes, PPC is also switchable, as is MIPS (my R4000 SGI boxes are big endian, while my R4000 Jazz box (Olivetti M700-10) is little endian). https://en.wikipedia.org/wiki/Endianness#Bi-endianness https://en.wikipedia.org/wiki/Endianness#Bi-endianness lists ARM >= v3, PowerPC, Alpha, SPARC V9, MIPS, PA-RISC, SuperH SH-4 and IA-64 as bi-endian (can be configured as wither). MIPS is still used a lot in routers. I don't know if the MIPS-compatible PIC32 is also bi-endian - there's maybe no reason it should be. About ARM, I don't think I have run into any BE-mode ARM systems in a while, but I do recall using big-endian gcc versions for something in the past. And apparently some folks are running Cubieboards in big endian mode (if that's common or not for Cubieboards/Cubietrucks I don't know). Yeah, network protocols will keep BE alive if nothing else - and yet, the Power 7 systems I'm coding for at the moment are big endian and IBM won't change that in the reasonably long term.
