Struct TraceIterator 

pub struct TraceIterator<'a> { /* private fields */ }

opencoder.py: TraceIterator — iterates operations in a trace with dead range tracking.

The iterator walks through encoded trace operations and maintains live/dead range information for each value (OpRef). This enables the optimizer to know which values are still in use at each point.

Implementations

impl<'a> TraceIterator<'a>

pub fn new(ops: &'a [Op]) -> Self

Create a new TraceIterator over the given operations.

pub fn next_op(&mut self) -> Option<&'a Op>

Get the next operation, or None if exhausted.

pub fn position(&self) -> usize

Current position in the operation list.

pub fn done(&self) -> bool

Whether all operations have been consumed.

pub fn num_ops(&self) -> usize

Total number of operations.

pub fn reset(&mut self)

Reset to the beginning.

pub fn compute_dead_ranges(&mut self) -> &[usize]

opencoder.py: get_dead_ranges() — compute live ranges for all values. Returns a reference to the live_range_end map.

pub fn is_dead_at(&self, opref: OpRef, pos: usize) -> bool

Check if a value is dead at the given position. opencoder.py: is_dead(opref, pos)
