Struct LICMProfileData 

pub struct LICMProfileData {
    pub loop_counts: HashMap<LcnfVarId, u64>,
    pub binding_counts: HashMap<LcnfVarId, u64>,
}

Profiling data used to guide LICM decisions.

Fields

loop_counts: HashMap<LcnfVarId, u64>

Execution counts for each loop (by header var id).

binding_counts: HashMap<LcnfVarId, u64>

Execution counts for each let-binding (by var id).

Implementations

impl LICMProfileData

pub fn new() -> Self

Create a new empty profile.

pub fn record_loop(&mut self, header: LcnfVarId, count: u64)

Record an execution count for a loop.

pub fn loop_count(&self, header: LcnfVarId) -> u64

Get the execution count for a loop (default 1 if unknown).

pub fn record_binding(&mut self, var: LcnfVarId, count: u64)

Record an execution count for a binding.

pub fn dynamic_savings(&self, candidate: &HoistCandidate) -> u64

Compute the dynamic savings for a hoist candidate given profile data.
