Endianess Swapping

I'm trying to port some code currently being compiled by gcc that uses the __builtin_bswapXX functions. Is there an equivalent in ARM C6 or will I need to provide it myself?
Endian Swap

Hi, Is there any ARM inline function to switch between Little and Big Endian ? I know the Keil feature to compile the whole code in BE or LE, but i would like any function to swap just some words...
swap equivelant.

Hi, Is there an equivelan function or keyword to "swap"? Is there anyway to get the high or lower nibbles of a variable or swap them in C? any help would be appreciated. -=N
