Provided Methods

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

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

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

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