Re: lto gimple types and debug info

That is one example of extremely important information which requires

But not all the trees implementing those types (and all the
cross-references between those, that are important for parsing but not
interesting at all for the middle-end). All you need is a tag (alias set
number) per type and a graph giving the conflicts between those tags.

With that level of information, how do you "link" the alias trees for different modules at LTO time?
