ATTINY416/816 Brown Out Detector
Wow, thats weird behaviour.  The sampled operation is completely broken.    The reason for using sampled would be to wake up when you go from battery to DC supply...

Poor Code generation for M0 Arm Cores
Yes, I have seen that optimisation as well with Cortex-M3, but with M0 it is not consistently applied when it can be.  M3 code generation is much better at applying these...

Poor Code generation for M0 Arm Cores
The ARM GCC maintainers are looking into the bug now, which is good.  But there is definitely something weird going on.  And it does seem like it has something to do...
