Hi all,

Does anyone happen to know if there are *any* 32-bit architectures (on which Linux runs) for which the ABI for a "long long" is different from passing two "longs" in the appropriate order, i.e. (hi,lo) for bigendian or (lo,hi) for littleendian?

I'd like to switch klibc to use the 64-bit file ABI thoughout, but it's a considerable porting effort, and I'm trying to figure out how to best manage it.


I don't know how it is for GCC, but when using the Sun compiler, "long long" for 32-bit is low-high, while "long long" (or just long) for 64-bit is high-low. This has been an annoyance to me. :)
