The only one I know of is Boehm, which at the bottom is a traditional mark and sweep. It probably uses various techniques to optimize this, but typically incremental/generational/compacting GC's will be hard to create for C++ without going for a managed subset such as what you can get with .Net C++. Some of the approaches that needs to move pointers can be implemented with compiler support for pinning pointers or read/write blocks though, but the effect on performance may be too big, and it isn't necessarily non-trivial changes to the GC.
