Re: [avr-gcc-list] Strings in upper 64K

[dimax un]

BTW how to make GCC not to cross 64K boundary while allocating ROM constants? Is any care required to make sure it will not happen?

Not that I know of -- it would require using a "memory model" with
32-bit pointers, as GCC doesn't support 24-bit pointers at all.
What's your issue with it, do you have more than 64 KB of ROM
constants?

Of course, you can always place your strings anywhere, it's only that
all those ..._P() functions can only handle the lower 64 KB of ROM.
