Semantics? I know that LLD discarded the all-format architecture of gnu ld; arguably it got that idea from gold which is ELF only. But what semantics did it discard?

I'm a huge fan of LLD by the way. But in addition to performance and its implementation architecture, I think licensing had something to do with LLD's success.

> The semantics of LLD’s archive handling are different from the traditional Unix’s. You can observe it if you carefully craft archive files to exploit it. However, in reality, we don’t know any program that cannot link with our algorithm so far, so it’s not going to cause trouble.

I run into issues with these updated semantics not exactly routinely, but with some regularity. They can always be fixed, but often it is an annoying hassle.
