Re: AVR byte swap optimization

[Eric Christopher]

   It isn't only on the AVR that bswap_32() is nontrivial to get  
right.
These two versions would rule on the i386 if GCC would be just a  
little bit
smarter:

I prefer the single instruction bswap that we now generate for  
__builtin_bswap[32,64] myself...
