// Please update this information when this file changes
// Implementation of class OrderAccess.

// Machine barrier instructions:
//
// - sync Two-way memory barrier, aka fence.
// - lwsync orders Store|Store,
// Load|Store,
// Load|Load,
// but not Store|Load
// - eieio orders Store|Store
// - isync Invalidates speculatively executed instructions,
// but isync may complete before storage accesses
// associated with instructions preceding isync have
// been performed.
//
// Semantic barrier instructions:
// (as defined in orderAccess.hpp)
//
// - release orders Store|Store, (maps to lwsync)
// Load|Store
// - acquire orders Load|Store, (maps to lwsync)
// Load|Load
// - fence orders Store|Store, (maps to sync)
// Load|Store,
// Load|Load,
// Store|Load
