DEF_SECTION (objc_cls_refs_section, SECTION_MERGE, ".objc_cls_refs", 1) If I've got this correct - this is implementing the constraint that class names are global in the NeXT runtime [at least at release 0/1]. I assume that the section merge arranges that all references to class FOO point to the same and unique class definition. > > Well, obviously some Objective-C maintainer needs to chime in and explain > things. indeed. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43061
