Type Alias miri::concurrency::weak_memory::AllocState

pub type AllocState = StoreBufferAlloc;

Aliased Type

struct AllocState {
    store_buffers: RefCell<RangeObjectMap<StoreBuffer>>,
}

Fields

store_buffers: RefCell<RangeObjectMap<StoreBuffer>>

Store buffer of each atomic object in this allocation

Implementations

impl StoreBufferAlloc

pub fn new_allocation() -> Self

fn is_overlapping(&self, range: AllocRange) -> bool

Checks if the range imperfectly overlaps with existing buffers Used to determine if mixed-size atomic accesses

pub fn memory_accessed(&self, range: AllocRange, global: &DataRaceState)

When a non-atomic access happens on a location that has been atomically accessed before without data race, we can determine that the non-atomic access fully happens after all the prior atomic accesses so the location no longer needs to exhibit any weak memory behaviours until further atomic accesses.

fn get_or_create_store_buffer<'tcx>( &self, range: AllocRange, init: Scalar<Provenance> ) -> InterpResult<'tcx, Ref<'_, StoreBuffer>>

Gets a store buffer associated with an atomic object in this allocation, or creates one with the specified initial value if no atomic object exists yet.

fn get_or_create_store_buffer_mut<'tcx>( &mut self, range: AllocRange, init: Scalar<Provenance> ) -> InterpResult<'tcx, &mut StoreBuffer>

Gets a mutable store buffer associated with an atomic object in this allocation

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
