Details:

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
