Did you try with:


I ran into similar problems with code size and these options made the code fit in a bootloader area (however my bootloader is much bigger thant 512 bytes)

I've also seen that EEPROM related function calls were inlined each time, so I wrote a couple of wrapper functions to avoid this inlining.

I've noticed that too. My Arduino bootloader fits into the 512 byte boot section when compiled with avr-gcc 3.4, but doesn't when compiled with avr-gcc 4.3.

You've found an even closer gap with the jump between 4.1 and 4.3.
