Hi,

I would like to add swap32 built in function to gcc. I looked how other

built in functions are implemented, but I didn't managed.

Can someone give me some idea what to do?

Aleksandar

If you mean something like __builtin_bswap32, just use it ;)

If you mean something else... explain in better detail.

Paolo.
