Sorry, why should simulavrxx not be able to run automated testsuites?
The simulator has an scripting interface (tcl/python/... all what swig can
generate!), it is able to read elf files
it executes code also with ram/ext-ram eeprom and flash configurations
also with nearly exact timing and results could also be generated like
interrupt statistics and a lot more. And the gdb interface is also still
alive
where all intermediate steps could be watched in detail also automated like
the regressin tests from Theodore show. What is missing for automated
testsuite? No problem to implement this. Please give me a detailed
requirement list
and I will implement this. (I hope the list not so long :-)))
For a faster comparion maybe a elf file write could help where the
ram/flash/eeprom is written out and could be compared again a given 
file. If that is needed or any other add on or change, let me know.

That is what the simulator is good for. Simply check the results of a run.
The way how the result was generated is not interesting and can differ
from according to compiler command line option. OK, for binutils it doesn´t
matter
because the same input kust result int the same output :-)
