pub enum ValueLoc {
    Unassigned,
    Reg(RegUnit),
    Stack(StackSlot),
}

Value location.

Variants

Unassigned

This value has not been assigned to a location yet.

Reg(RegUnit)

Value is assigned to a register.

Stack(StackSlot)

Value is assigned to a stack slot.

Implementations

impl ValueLoc

pub fn is_assigned(self) -> bool

Is this an assigned location? (That is, not Unassigned).

pub fn unwrap_reg(self) -> RegUnit

Get the register unit of this location, or panic.

pub fn unwrap_stack(self) -> StackSlot

Get the stack slot of this location, or panic.

pub fn display<'a, R: Into<Option<&'a RegInfo>>>(
    self,
    regs: R
) -> DisplayValueLoc<'a>

Return an object that can display this value location, using the register info from the target ISA.
