Betreff: [avr-gcc-list] Interrupt overhead again

Hello!

Currently (avr-gcc 3.4.3), the interrupt prologue/epilogue accounts to a
total of 65 cycles, if any function call is made in the ISR.

Can I do anything do reduce this prologue besides removing all function
calls or forcing them to be inline?
