Struct LiveInterval 

pub struct LiveInterval {
    pub vreg: VirtualReg,
    pub start: usize,
    pub end: usize,
    pub weight: u64,
}

Live interval: the range [start, end] of instruction indices (0-based, counting sequentially across all blocks in program order) during which vreg must be kept alive.

Fields

vreg: VirtualReg

start: usize

Index of the instruction that first defines vreg.

end: usize

Index of the last instruction that uses vreg.

weight: u64

Estimated execution frequency summed over uses and definitions.
