Yes, some kind of lazy ahead-of-time compilation. By default the native compiler kicks in as soon as Emacs finds a bytecompiled file without a machine code equivalent. The resulting machine code is cached then for future use so this only happens once per a single *.elc file. At least this is what i remember from the last time I checked the code :-)
