[dylanmckay]

I don't believe this is related to issue #18, but that is only speculation. What code produces this assertion error?

[4ntoine]

I've found getFrameRegister is not implemented:

https://github.com/dylanmckay/avr-llvm/blob/avr-support/lib/Target/AVR/AVRRegisterInfo.cpp#L248

[4ntoine]

According to the doc:

getFrameRegister - This method should return the register used as a base for values allocated in the current stack frame.
