I don't think we need the special notation: in fact, herd7 doesn't know anything about these lk-rmw or rmw links between lock events until after tools/memory-model/ (the .cat file) has established such links cf. (* Link Lock-Reads to their RMW-partner Lock-Writes *) let lk-rmw = ([LKR] ; po-loc ; [LKW]) \ (po ; po) let rmw = rmw | lk-rmw I was trying to be informative (since that says "lk-rmw is a subrelation of rmw) but, in order to be faithful to the scope of this document (herd representation), the doc should really just indicate LKR ->po LKW. Thoughts? Andrea
