C++ frontend produce same body aliases and extra name aliases for virtual functions and vtables that are obviously equivalent. Those aliases are bit special, especially because C++ frontend visibility code is so ugly it can not get them right at first time and their visibility needs to be copied from their "masters" at the end of parsing.

The symbol will be assumed to be used in an invisiable way (like by an toplevel asm statement).

Like FORCE_OUTPUT, but in the case it is ABI requiring the symbol to be exported. Unlike FORCE_OUTPUT this flag gets cleared to symbols promoted to static and it does not inhibit optimization.

Linked list of symbols with the same asm name. There may be multiple entries for single symbol name during LTO, because symbols are renamed only after partitioning.
Because inline clones are kept in the assembler name has, they also produce duplicate entries.
There are also several long standing bugs where frontends and builtin code produce duplicated decls.
