Expand description

Configuration needed to spawn a Miri instance.

Fields§

§env: Vec<(OsString, OsString)>

The host environment snapshot to use as basis for what is provided to the interpreted program. (This is still subject to isolation as well as forwarded_env_vars.)

§validate: bool

Determine if validity checking is enabled.

§borrow_tracker: Option<BorrowTrackerMethod>

Determines if Stacked Borrows is enabled.

§check_alignment: AlignmentCheck

Controls alignment checking.

§check_abi: bool

Controls function ABI checking.

§isolated_op: IsolatedOp

Action for an op requiring communication with the host.

§ignore_leaks: bool

Determines if memory leaks should be ignored.

§forwarded_env_vars: Vec<String>

Environment variables that should always be forwarded from the host.

§args: Vec<String>

Command-line arguments passed to the interpreted program.

§seed: Option<u64>

The seed to use when non-determinism or randomness are required (e.g. ptr-to-int cast, getrandom()).

§tracked_pointer_tags: FxHashSet<BorTag>

The stacked borrows pointer ids to report about

§tracked_call_ids: FxHashSet<CallId>

The stacked borrows call IDs to report about

§tracked_alloc_ids: FxHashSet<AllocId>

The allocation ids to report about.

§data_race_detector: bool

Determine if data race detection should be enabled

§weak_memory_emulation: bool

Determine if weak memory emulation should be enabled. Requires data race detection to be enabled

§track_outdated_loads: bool

Track when an outdated (weak memory) load happens.

§cmpxchg_weak_failure_rate: f64

Rate of spurious failures for compare_exchange_weak atomic operations, between 0.0 and 1.0, defaulting to 0.8 (80% chance of failure).

§measureme_out: Option<String>

If Some, enable the measureme profiler, writing results to a file with the specified prefix.

§panic_on_unsupported: bool

Panic when unsupported functionality is encountered.

§backtrace_style: BacktraceStyle

Which style to use for printing backtraces.

§provenance_mode: ProvenanceMode

Which provenance to use for int2ptr casts

§mute_stdout_stderr: bool

Whether to ignore any output by the program. This is helpful when debugging miri as its messages don’t get intermingled with the program messages.

§preemption_rate: f64

The probability of the active thread being preempted at the end of each basic block.

§report_progress: Option<u32>

Report the current instruction being executed every N basic blocks.

§retag_fields: RetagFields

Whether Stacked Borrows retagging should recurse into fields of datatypes.

§external_so_file: Option<PathBuf>

The location of a shared object file to load when calling external functions FIXME! consider allowing users to specify paths to multiple SO files, or to a directory

§gc_interval: u32

Run a garbage collector for BorTags every N basic blocks.

§num_cpus: u32

The number of CPUs to be reported by miri.

§page_size: Option<u64>

Requires Miri to emulate pages of a certain size
