--- Comment #10 from Andi Kleen <andi-gcc at firstfloor dot org> 2011-09-29 18:19:02 UTC --- I did the same patch (with long long) I think using long long here is ok because lto-plugin only builds on modern and non weird hosts and they should all have long long anyways. uint64_t is probably fine too.
