[avr-libc-dev] Assembler arithmetic

[Andrew Hutchinson]

I want to dynamically pick out a byte from a symbol.

I know I can use lo8(x) .. hhi8(x) - or whatever it is. But these are fixed.

I want to improve and simplify avr-gcc instructions. In this situation I 
need to iterate through each byte of a symbol - without a bunch of 
string manipulations.

Is this possible?
