Enum TraceLookup 

pub enum TraceLookup {
    NotHot,
    StartRecording,
    Ran {
        resume_ip: usize,
    },
    GuardMismatch,
    Skip,
}

Outcome of consulting the trace cache at a backward-branch site.

Variants

NotHot

Header not yet hot — interpreter continues. Counter was bumped.

StartRecording

Header crossed TRACE_THRESHOLD and no compiled trace exists yet. The interpreter should arm the recorder for the next iteration.

Ran

A compiled trace ran. The interpreter should resume at this IP.

Fields

resume_ip: usize

GuardMismatch

A compiled trace exists but the slot type guard failed. Interpreter handles this iteration normally.

Skip

Trace was previously aborted or blacklisted; never retry.
