Provided Methods

fn validate_overlapping_atomic( &self, place: &MPlaceTy<'tcx, Provenance> ) -> InterpResult<'tcx>

fn buffered_atomic_rmw( &mut self, new_val: Scalar<Provenance>, place: &MPlaceTy<'tcx, Provenance>, atomic: AtomicRwOrd, init: Scalar<Provenance> ) -> InterpResult<'tcx>

fn buffered_atomic_read( &self, place: &MPlaceTy<'tcx, Provenance>, atomic: AtomicReadOrd, latest_in_mo: Scalar<Provenance>, validate: impl FnOnce() -> InterpResult<'tcx> ) -> InterpResult<'tcx, Scalar<Provenance>>

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

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

Caller should never need to consult the store buffer for the latest value. This function is used exclusively for failed atomic_compare_exchange_scalar to perform load_impl on the latest store element
