TraceJitConfig

Struct TraceJitConfig 

Source
pub struct TraceJitConfig {
    pub trace_threshold: u32,
    pub max_side_exits: u32,
    pub max_inline_recursion: usize,
    pub max_trace_chain: usize,
    pub max_trace_len: usize,
}
Expand description

Tunable thresholds for the tracing JIT.

All hot/threshold/cap values are surfaced here so callers can adjust the JIT for their workload without recompiling fusevm. Defaults match the constants used through phase 9; aggressive workloads (very hot short loops) might want lower thresholds, while cold-start workloads (script that runs once) might want higher thresholds to avoid spending compile time on traces that won’t pay off.

Apply via JitCompiler::set_config(...) — affects subsequent calls from the current thread.

Fields§

§trace_threshold: u32

Backedges through a loop header before recording arms.

§max_side_exits: u32

Mid-trace side-exits before the trace is auto-blacklisted.

§max_inline_recursion: usize

Maximum self-recursive levels the recorder will inline.

§max_trace_chain: usize

Maximum chained side traces dispatched per backward-branch hop.

§max_trace_len: usize

Maximum recorded ops in a single trace before recording aborts.
