Expand description

Runtime configuration.

Fields§

§enabled: bool

Whether compiled-code lookup is enabled.

Defaults to false (safe rollout default).

§thread_name: String

Name for the backend thread.

Defaults to "revmc-backend".

§store: Option<Arc<dyn ArtifactStore>>

Artifact store for loading precompiled AOT artifacts.

None means no AOT preload—only JIT will populate the map (in later phases).

§tuning: RuntimeTuning

Tuning knobs.

§dump_dir: Option<PathBuf>

Base directory for compiler debug dumps.

When set, the compiler dumps IR, assembly, and bytecode for each compiled contract to {dump_dir}/{spec_id}/{code_hash}/.

Defaults to None (no dumps).

§debug_assertions: bool

Enable debug assertions in compiled code.

When true, the compiler inserts runtime checks (e.g. stack bounds) that panic! on violation. Useful for diagnosing JIT correctness bugs.

Defaults to false.

§no_dedup: bool

Disable the block deduplication pass.

When true, the dedup pass that merges identical basic blocks is skipped. Useful for isolating dedup-related JIT correctness bugs.

Defaults to false.

§no_dse: bool

Disable the dead store elimination pass.

When true, DSE is skipped. Useful for debugging JIT correctness issues where DSE incorrectly eliminates live stack operations.

Defaults to false.

§gas_params: Option<GasParams>

Custom gas parameters for compile-time gas folding.

Overrides the default gas schedule derived from spec_id when compiling bytecode. Useful for custom chains with non-standard gas costs (e.g. modified SSTORE, CREATE, or EXP costs).

When None, the compiler uses GasParams::new_spec(spec_id).

Defaults to None.

§aot: bool

AOT mode: observed misses are promoted to AOT compilation instead of JIT.

Defaults to false.

§blocking: bool

Blocking mode: every lookup synchronously JIT-compiles on miss and never falls back to the interpreter.

When true, lookup() behaves like lookup_blocking(): if the compiled function is not already resident, the calling thread blocks until JIT compilation completes. This implies enabled = true and jit_hot_threshold = 0.

Intended for debugging and testing only — not for production use.

Defaults to false.

§on_compilation: Option<Arc<dyn Fn(CompilationEvent) + Send + Sync>>

Callback invoked after each compilation completes (success or failure).

Defaults to None.
