Example 21 with EventData

use of com.dat3m.dartagnan.verification.model.EventData in project Dat3M by hernanponcedeleon.

the class RMWGraph method repopulate.

/* Right now there are four cases where the RMW-Relation is established:
     (1) LOCK : Load -> CondJump -> Store
     (2) RMW : RMWLoad -> RMWStore (completely static)
     (3) ExclAccess : ExclLoad -> ExclStore (dependent on control flow)
     (4) Atomic blocks: BeginAtomic -> Events* -> EndAtomic

     We need to keep this in line with the implementation of RelRMW!
