There were some changes to the compiler as well, adding some hooks when a dynamic library is loaded. But that shouldn't be needed on OS X since the dynamic linker have native support for this.
Yes, you need a constructor and destructor in each shared library that call into druntime to register all modules, EH handlers and such things.
There is some Mach-O support to be notified (via a callback) when a new shared library is loaded. It wasn't possible to unset that callback though, meaning it would segfault when druntime itself is unloaded.
So either we get this runtime linker stuff to work or we simply use __attribute__((constructor))/__attribute__((destructor)) functions like on linux.
