Provided Methods

fn allow_data_races_ref<R>( &self, op: impl FnOnce(&MiriInterpCx<'tcx>) -> R, ) -> R

Temporarily allow data-races to occur. This should only be used in one of these cases:

• One of the appropriate validate_atomic functions will be called to treat a memory access as atomic.
• The memory being accessed should be treated as internal state, that cannot be accessed by the interpreted program.
• Execution of the interpreted program execution has halted.

fn allow_data_races_mut<R>( &mut self, op: impl FnOnce(&mut MiriInterpCx<'tcx>) -> R, ) -> R

Same as allow_data_races_ref, this temporarily disables any data-race detection and so should only be used for atomic operations or internal state that the program cannot access.

fn atomic_access_check( &self, place: &MPlaceTy<'tcx>, access_type: AtomicAccessType, ) -> InterpResult<'tcx>

Checks that an atomic access is legal at the given place.

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

Update the data-race detector for an atomic read occurring at the associated memory-place and on the current thread.

fn validate_atomic_store( &mut self, place: &MPlaceTy<'tcx>, atomic: AtomicWriteOrd, ) -> InterpResult<'tcx>

Update the data-race detector for an atomic write occurring at the associated memory-place and on the current thread.

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

Update the data-race detector for an atomic read-modify-write occurring at the associated memory place and on the current thread.

fn validate_atomic_op<A: Debug + Copy>( &self, place: &MPlaceTy<'tcx>, atomic: A, access: AccessType, op: impl FnMut(&mut MemoryCellClocks, &mut ThreadClockSet, VectorIdx, A) -> Result<(), DataRace>, ) -> InterpResult<'tcx>
