I was mostly worried about ordering issues. pointer_set is not stable across memory layout changes and we may end up outputting warnings/merging binfos in random orders. This seemed uncool. Maybe the final form is quite safe, since we do everything with the designated leader, but I would rather keep this here rather than later go into nasty issues of divergences in between compilation on different hosts.
OK, sure.
I will leave this for incremental update and discuss it with Richard.
OK.
I see, I wondered if I can get mangling of type names. So, once we will need uniqueness of ODR types for C++ (probably for alias info), we can basically convince C++ FE to produce the mangling and then discover and match ODR types based on presence of the assembler names?
Yes.
Can't this be used for merging of dwarf debug info on types?
Possibly, but we already have several ways to merge dwarf debug info for types: .debug_types and dwz come to mind first.
