Module jit 

Rust-only tracing JIT implementation details.

This module consumes VM execution observations directly. It neither reads Evaluation Journal events nor changes HALC.

Modules

backend

hotness

native

Optional machine-code backend. Trace IR is lowered to a tiny wasm module and Wasmtime/Cranelift compiles that module to host code. This reuses the runtime’s existing native Cranelift dependency and adds nothing to wasm or default builds.

recorder

trace_ir

Structs

JitTelemetry

Per-program tracing-JIT counters. They make it possible to distinguish a cold loop, an unsupported trace, and a trace that is compiled but exits.
