Provided Methods

fn read_scalar_atomic( &self, place: &MPlaceTy<'tcx>, atomic: AtomicReadOrd, ) -> InterpResult<'tcx, Scalar>

Perform an atomic read operation at the memory location.

fn write_scalar_atomic( &mut self, val: Scalar, dest: &MPlaceTy<'tcx>, atomic: AtomicWriteOrd, ) -> InterpResult<'tcx>

Perform an atomic write operation at the memory location.

fn atomic_rmw_op_immediate( &mut self, place: &MPlaceTy<'tcx>, rhs: &ImmTy<'tcx>, op: BinOp, not: bool, atomic: AtomicRwOrd, ) -> InterpResult<'tcx, ImmTy<'tcx>>

Perform an atomic RMW operation on a memory location.

fn atomic_exchange_scalar( &mut self, place: &MPlaceTy<'tcx>, new: Scalar, atomic: AtomicRwOrd, ) -> InterpResult<'tcx, Scalar>

Perform an atomic exchange with a memory place and a new scalar value, the old value is returned.

fn atomic_min_max_scalar( &mut self, place: &MPlaceTy<'tcx>, rhs: ImmTy<'tcx>, min: bool, atomic: AtomicRwOrd, ) -> InterpResult<'tcx, ImmTy<'tcx>>

Perform an conditional atomic exchange with a memory place and a new scalar value, the old value is returned.

fn atomic_compare_exchange_scalar( &mut self, place: &MPlaceTy<'tcx>, expect_old: &ImmTy<'tcx>, new: Scalar, success: AtomicRwOrd, fail: AtomicReadOrd, can_fail_spuriously: bool, ) -> InterpResult<'tcx, Immediate<Provenance>>

Perform an atomic compare and exchange at a given memory location. On success an atomic RMW operation is performed and on failure only an atomic read occurs. If can_fail_spuriously is true, then we treat it as a “compare_exchange_weak” operation, and some portion of the time fail even when the values are actually identical.

fn atomic_fence(&mut self, atomic: AtomicFenceOrd) -> InterpResult<'tcx>

Update the data-race detector for an atomic fence on the current thread.

fn allow_data_races_all_threads_done(&mut self)

After all threads are done running, this allows data races to occur for subsequent ‘administrative’ machine accesses (that logically happen outside of the Abstract Machine).

fn release_clock<'a>(&'a self) -> Option<Ref<'a, VClock>>

where 'tcx: 'a,

Returns the release clock of the current thread. Other threads can acquire this clock in the future to establish synchronization with this program point.

fn acquire_clock(&self, clock: &VClock)

Acquire the given clock into the current thread, establishing synchronization with the moment when that clock snapshot was taken via release_clock.
