Re: [avr-llvm-devel] Load / Store

[Borja F. <bor...@gm...>]

Ahh thanks for the replies, this brings to me some other doubts. If gcc
doesnt support different ptr sizes, when it comes to the code emission
stage, when doing a load or a store for the 8bit ptr case, does it move the
whole reg pair addr to X/Y/Z or it knows it only needs the lower half
because the upper is always 0, otherwise it is a huge waste.

If clang supports named spaces then it's great as Kevin pointed out.
I'm a bit concerend about portability in different devices because
sizeof(void *) is going to be 1, 2 or 3, do you think this can cause any
issues?
About what John mentioned, what would you suggest Eric to overcome this
issue? you're the libc expert here, so how would you manage different ptr
sizes in the library?
