Enum cranelift_codegen::ir::dfg::ValueDef

pub enum ValueDef {
    Result(Inst, usize),
    Param(Ebb, usize),
}

Where did a value come from?

Variants

Result(Inst, usize)

Value is the n'th result of an instruction.

Param(Ebb, usize)

Value is the n'th parameter to an EBB.

Methods

impl ValueDef

pub fn unwrap_inst(&self) -> Inst

Unwrap the instruction where the value was defined, or panic.

pub fn unwrap_ebb(&self) -> Ebb

Unwrap the EBB there the parameter is defined, or panic.

pub fn pp(self) -> ExpandedProgramPoint

Get the program point where the value was defined.

pub fn num(self) -> usize

Get the number component of this definition.

When multiple values are defined at the same program point, this indicates the index of this value.

Trait Implementations

impl From<ValueDef> for ProgramPoint

fn from(def: ValueDef) -> Self

Performs the conversion.

impl From<ValueDef> for ExpandedProgramPoint

fn from(def: ValueDef) -> Self

Performs the conversion.

impl PartialEq<ValueDef> for ValueDef

fn eq(&self, other: &ValueDef) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ValueDef) -> bool

This method tests for !=.

impl Eq for ValueDef

impl Copy for ValueDef

impl Debug for ValueDef

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for ValueDef

fn clone(&self) -> ValueDef

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
