I was thinking of how to measure the performance of simulavrxx versus the other AVR simulators and I wondered if the Drystone benchmark might be one comparison. How long does it take to simulate a run of N iterations? How long on real hardware?

I am creating this to attach a slightly hacked dry.c file and instructions. I have no idea how to run this on simulavrxx since I don't have any examples which route avr-libc printf to stdout. Plus I don't have real hardware. :)

CC=avr-gcc \
CFLAGS="-O2 -mmcu=atmega128" \
sh dry.c
