Struct JitRuntime 

pub struct JitRuntime {
    pub hot_threshold: u32,
    /* private fields */
}

Available on crate feature jit only.

Runtime-wide JIT state: compiled traces are shared; each worker thread owns its own Cranelift module for compilation ([super::module_local]).

Fields

hot_threshold: u32

Implementations

impl JitRuntime

pub fn new(chunk: Arc<Chunk>, hot_threshold: u32) -> Self

pub fn with_default_threshold(chunk: Arc<Chunk>) -> Self

pub fn chunk(&self) -> Option<Arc<Chunk>>

Current bytecode image this cache was built for.

pub fn matches_chunk(&self, vm_chunk: &Arc<Chunk>) -> bool

True when vm_chunk is the same image as the JIT cache.

pub fn reload(&self, chunk: Arc<Chunk>)

Replace the bytecode image and discard stale compiled traces.

pub fn get_trace(&self, key: &TraceKey) -> Option<JitEntryCopy>

pub fn insert_trace(&self, key: TraceKey, trace: CompiledTrace)

pub fn record_hot_hit(&self, key: TraceKey) -> bool
