program logic based on endianness

Hi Everyone,

I have a program unit which does >> and << of an integer which is of
4 bytes length. The logic of shifting and action based on the result,
assumes that the system is big-endian.

Accordingly, if i need the program to work fine in a little-endian
system. I understand that the code needs to be changed.

I wanted to know if the above holds true for bitwise and (&) and
bitwise or (|). I think, the processor should take care of the
operation a&b or a|b irrespective of the endianness of the system.

Please provide your comments.

Thanks in advance!!!
