avr-gcc creating loop counters out of nothing, for no reason?
Over in another forum, ralphd posted about speeding up some SW SPI routines. ( http://nerdralph.blogspot.ca/201... )   But to me, the interesting thing is that avr-gcc is...

ISR Vector size
Is there a way for a C program to figure out the vector size (2 or 4 bytes) based on compiler predefined symbols and/or io.h ? I see that there is "#define __AVR_HAVE_JMP_CALL__ 1...
