Type Alias AllocState

Source
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

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.

Implementations

Source§

impl StoreBufferAlloc

Source

pub fn new_allocation() -> Self

Source

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 writes so the location no longer needs to exhibit any weak memory behaviours until further atomic accesses.

Source

fn get_store_buffer<'tcx>( &self, range: AllocRange, ) -> InterpResult<'tcx, Option<Ref<'_, StoreBuffer>>>

Gets a store buffer associated with an atomic object in this allocation. Returns None if there is no store buffer.

Source

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

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