[avr-gcc-list] swap bits

[Torsten Hahn]

Hi,

iam looking for a way, to efficiently swap all bits in an register. Can 
somebody help me with a little asm-macro or a pice of efficient c-code ?
It schould take an 8bit value as input an give back an value, where bi7 
of the input is now the bit 0, bit6 is bit1 etc.

I have no idea how to to this very well.

Thanks,
T. Hahn
