H A Dexplanation.txt25 17. ATOMIC UPDATES: rmw
975 ATOMIC UPDATES: rmw
978 What does it mean to say that a read-modify-write (rmw) update, such
1006 (R ->rmw W) implies (there is no X with R ->fr X and X ->co W),
1008 where the rmw relation links the read and write events making up each
1011 Atomic rmw updates play one more role in the LKMM: They can form "rmw
1012 sequences". An rmw sequence is simply a bunch of atomic updates where
1016 Z0 ->rf Y1 ->rmw Z1 ->rf ... ->rf Yn ->rmw Zn,
1019 degenerate case). We write this relation as: Z0 ->rmw-sequence Zn.
