Struct Range 

pub struct Range {
    pub start: Point,
    pub end: Point,
}

The stretch of the function a value is live over.

Both ends are included: a value written at a point and read at a later one is live at both, and one written and never read is live where it was written, because the register it was written to is not free at the instant it was written to. A value written early is written before the instruction reads its operands and is still written when the instruction is done, so even one nothing reads covers the whole of the instruction that wrote it.

Fields

start: Point

Where the value is written.

end: Point

The last place it is read, or where it is written if nothing reads it.

Implementations

impl Range

pub fn covers(self, point: Point) -> bool

Whether the value is live at that point.

pub fn overlaps(self, other: Self) -> bool

Whether two values are both live anywhere, which is what stops them sharing a register.
