Re: [avr-libc-dev] Amazing result!

[Peeter Vois]

Thanks for offering help.

One thing that could help a lot is to make simulation target running on
newer building tools. And so that it could be used older platforms
aswell.

Thing to do is to make the new barnch of simulation compiling
or to make simulavr 1.2.2.2 compiling with newer building tools. Another
thing that popped into my head is to make python based simulation- but
as we have simulavr this would be waste of time. Maybe the simulator of
avrora can be used as it talks gdb serial protocol too...
