This episode\nfinds us removing references to ArtMethod/ArtField/mirror.\n\nOne aspect of this change that I would like to call out specfically\nis that the utils versions of the \"Pretty*\" functions all were written\nto accept nullptr as an argument.  I have split these functions up as\nfollows:\n1) an instance method, such as PrettyClass that obviously requires\nthis !\u003d nullptr.\n2) a static method, that behaves the same way as the util method, but\ncalls the instance method if p !\u003d nullptr.\nThis requires using a full class qualifier for the static methods,\nwhich isn\u0027t exactly beautiful.  I have tried to remove as many cases\nas possible where it was clear p !\u003d nullptr.\n\nBug: 22322814\nTest: test-art-host\nChange-Id: I21adee3614aa697aa580cd1b86b72d9206e1cb24\n"

      "message": "Add mark compact collector.\n\nThe mark compact collector is a 4 phase collection, doing a normal\nfull mark_sweep, calculating forwarding addresses of objects in the\nfrom space, updating references of objects in the from space, and\nmoving the objects in the from space.\n\nSupport is diabled by default since it needs to have non movable\nclasses and field arrays. Performance numbers is around 50% as fast.\n\nThe main advantage that this has over semispace is that the worst\ncase memory usage is 50% since we only need one space isntead of two.\n\nTODO: Make field arrays and classes movable. This causes complication\nsince Object::VisitReferences relies on these, so if we update the\nfields of an object but another future object uses this object to\nfigure out what fields are reference fields it doesn\u0027t work.\n\nBug: 14059466\n\nChange-Id: I661ed3b71ad4dde124ef80312c95696b4a5665a1\n"
