Re: avr-gcc-12.1.0-x64-windows new warnings ?

Hi,

> Hmm isnt that loading 2bytes into one ?

well yes, ordinarily this would be the case. But I am specifically referring 
to programming close to hardware, where a register with offset 0 from the 
peripheral base address is configured from a linker script, and system headers 
defining (sub-)registers of that peripheral in terms of this base register 
with an array subscript.
The compiler has no idea how large the address space actually is, as the 
declaration suggests the "array" is only a single byte long. Hence the 
warning.

However, given that the warning complains at array offset "0", I just realised 
that the warning underlying the original mail:
seems to be due to gcc having become stricter / buggy. As Georg-Johann wrote:

Very interesting. I've had problems with this type of warning since gcc 9.2.0, 
though not necessarily on avr-gcc.
