pub struct VClockAlloc {
    alloc_ranges: RefCell<RangeMap<MemoryCellClocks>>,
}
Expand description

Vector clock metadata for a logical memory allocation.

Fields§

§alloc_ranges: RefCell<RangeMap<MemoryCellClocks>>

Assigning each byte a MemoryCellClocks.

Implementations§

source§

impl VClockAlloc

source

pub fn new_allocation( global: &GlobalState, thread_mgr: &ThreadManager<'_, '_>, len: Size, kind: MemoryKind<MiriMemoryKind>, current_span: Span ) -> VClockAlloc

Create a new data-race detector for newly allocated memory.

source

fn find_gt_index(l: &VClock, r: &VClock) -> Option<VectorIdx>

source

fn report_data_race<'tcx>( global: &GlobalState, thread_mgr: &ThreadManager<'_, '_>, mem_clocks: &MemoryCellClocks, access: AccessType, access_size: Size, ptr_dbg: Pointer<AllocId> ) -> InterpResult<'tcx>

Report a data-race found in the program. This finds the two racing threads and the type of data-race that occurred. This will also return info about the memory location the data-race occurred in.

source

pub fn read<'tcx>( &self, alloc_id: AllocId, access_range: AllocRange, machine: &MiriMachine<'_, '_> ) -> InterpResult<'tcx>

Detect data-races for an unsynchronized read operation, will not perform data-race detection if race_detecting() is false, either due to no threads being created or if it is temporarily disabled during a racy read or write operation for which data-race detection is handled separately, for example atomic read operations.

source

fn unique_access<'tcx>( &mut self, alloc_id: AllocId, access_range: AllocRange, write_type: NaWriteType, machine: &mut MiriMachine<'_, '_> ) -> InterpResult<'tcx>

source

pub fn write<'tcx>( &mut self, alloc_id: AllocId, range: AllocRange, machine: &mut MiriMachine<'_, '_> ) -> InterpResult<'tcx>

Detect data-races for an unsynchronized write operation, will not perform data-race threads if race_detecting() is false, either due to no threads being created or if it is temporarily disabled during a racy read or write operation

source

pub fn deallocate<'tcx>( &mut self, alloc_id: AllocId, range: AllocRange, machine: &mut MiriMachine<'_, '_> ) -> InterpResult<'tcx>

Detect data-races for an unsynchronized deallocate operation, will not perform data-race threads if race_detecting() is false, either due to no threads being created or if it is temporarily disabled during a racy read or write operation
