Provided Methods§
sourcefn read_scalar_atomic(
&self,
place: &MPlaceTy<'tcx, Provenance>,
atomic: AtomicReadOrd
) -> InterpResult<'tcx, Scalar<Provenance>>
fn read_scalar_atomic( &self, place: &MPlaceTy<'tcx, Provenance>, atomic: AtomicReadOrd ) -> InterpResult<'tcx, Scalar<Provenance>>
Perform an atomic read operation at the memory location.
sourcefn write_scalar_atomic(
&mut self,
val: Scalar<Provenance>,
dest: &MPlaceTy<'tcx, Provenance>,
atomic: AtomicWriteOrd
) -> InterpResult<'tcx>
fn write_scalar_atomic( &mut self, val: Scalar<Provenance>, dest: &MPlaceTy<'tcx, Provenance>, atomic: AtomicWriteOrd ) -> InterpResult<'tcx>
Perform an atomic write operation at the memory location.
sourcefn atomic_op_immediate(
&mut self,
place: &MPlaceTy<'tcx, Provenance>,
rhs: &ImmTy<'tcx, Provenance>,
op: BinOp,
neg: bool,
atomic: AtomicRwOrd
) -> InterpResult<'tcx, ImmTy<'tcx, Provenance>>
fn atomic_op_immediate( &mut self, place: &MPlaceTy<'tcx, Provenance>, rhs: &ImmTy<'tcx, Provenance>, op: BinOp, neg: bool, atomic: AtomicRwOrd ) -> InterpResult<'tcx, ImmTy<'tcx, Provenance>>
Perform an atomic operation on a memory location.
sourcefn atomic_exchange_scalar(
&mut self,
place: &MPlaceTy<'tcx, Provenance>,
new: Scalar<Provenance>,
atomic: AtomicRwOrd
) -> InterpResult<'tcx, Scalar<Provenance>>
fn atomic_exchange_scalar( &mut self, place: &MPlaceTy<'tcx, Provenance>, new: Scalar<Provenance>, atomic: AtomicRwOrd ) -> InterpResult<'tcx, Scalar<Provenance>>
Perform an atomic exchange with a memory place and a new scalar value, the old value is returned.
sourcefn atomic_min_max_scalar(
&mut self,
place: &MPlaceTy<'tcx, Provenance>,
rhs: ImmTy<'tcx, Provenance>,
min: bool,
atomic: AtomicRwOrd
) -> InterpResult<'tcx, ImmTy<'tcx, Provenance>>
fn atomic_min_max_scalar( &mut self, place: &MPlaceTy<'tcx, Provenance>, rhs: ImmTy<'tcx, Provenance>, min: bool, atomic: AtomicRwOrd ) -> InterpResult<'tcx, ImmTy<'tcx, Provenance>>
Perform an conditional atomic exchange with a memory place and a new scalar value, the old value is returned.
sourcefn atomic_compare_exchange_scalar(
&mut self,
place: &MPlaceTy<'tcx, Provenance>,
expect_old: &ImmTy<'tcx, Provenance>,
new: Scalar<Provenance>,
success: AtomicRwOrd,
fail: AtomicReadOrd,
can_fail_spuriously: bool
) -> InterpResult<'tcx, Immediate<Provenance>>
fn atomic_compare_exchange_scalar( &mut self, place: &MPlaceTy<'tcx, Provenance>, expect_old: &ImmTy<'tcx, Provenance>, new: Scalar<Provenance>, 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.
sourcefn atomic_fence(&mut self, atomic: AtomicFenceOrd) -> InterpResult<'tcx>
fn atomic_fence(&mut self, atomic: AtomicFenceOrd) -> InterpResult<'tcx>
Update the data-race detector for an atomic fence on the current thread.
sourcefn allow_data_races_all_threads_done(&mut self)
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).
