Struct Live 

pub struct Live { /* private fields */ }

What is live where.

Implementations

impl Live

pub fn of(func: &Func, order: &Order) -> Self

Works it out for a function laid out in that order.

pub fn range(&self, reg: Reg) -> Option<Range>

Where a virtual register is live, or None for one this function never mentions and for a physical register.

pub fn live_in(&self, block: Block) -> impl Iterator<Item = Reg> + '_

Every virtual register that arrives in a block already holding a value.

The block’s own parameters are not among them. A parameter is written where it arrives, which makes it a value the block defines rather than one it inherits.

pub fn live_out(&self, block: Block) -> impl Iterator<Item = Reg> + '_

Every virtual register that is still wanted after a block, which is what its successors and the arguments its terminator carries between them ask for.
