Hi all,

I finally got around to porting the druntime module registry system we are using on the ELF-based Posixen to OS X. This allows shared library support to work in a natural way.

There are still some minor additions to make (module conflict detection, automatic library dependency tracking). But apart from that, what I currently have passes the complete test suite, which notably also includes runtime loading/unloading of D shared libraries.

If you are keen to give it a try, you can get the code from and build with "cmake -DBUILD_SHARED_LIBS=ON …".

I expect to land the feature in master by the end of August, but until then, there are also some upstreaming considerations to work out (it won't work out of the box with DMD, but for somebody familiar with DMD's backend it would be trivial to make the necessary adjustments).
