[Icc-avr] Optimization of write and read to register STS, LDS

[Bengt Ragnemalm]

I am testing a size optimized osccal routine (RetroDan, AVRfreaks). It is a
hint there about the possibility to optimize many STS and LDS instructions
with LDD and STD (load and store with displacement).

It occured to me that why could a C-compiler not catch that possibility? Or
maybe it would be possible to "fool" the compiler to use it anyway.
