What is the state of incremental linkers? ?I thought those existed now.

I think in some specific cases.  I've heard there's a microsoft one? It would be windows only of course.  Is anyone using that with ghc?

gold is supposed to be multi-threaded and fast (don't know about incremental), but once again it's ELF-only.  I've heard a few people talking about gold with ghc, but I don't know what the results were.

Unfortunately I'm on OS X, I don't know about any incremental or multithreaded linking here.

Neither do I. On my older machine with 2GB RAM, builds are often dominated by ld because it starts thrashing. And not many linkers target Mach-O. I've been toying with building my own ld replacement. I don't know anything about linkers, but I'd say at least even odds that I can do better than this. John L.
