Enum ValueDef

source
pub enum ValueDef {
    Result(Inst, usize),
    Param(Block, usize),
    Union(Value, Value),
}
Expand description

Where did a value come from?

Variants§

§

Result(Inst, usize)

Value is the n’th result of an instruction.

§

Param(Block, usize)

Value is the n’th parameter to a block.

§

Union(Value, Value)

Value is a union of two other values.

Implementations§

source§

impl ValueDef

source

pub fn unwrap_inst(&self) -> Inst

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

source

pub fn inst(&self) -> Option<Inst>

Get the instruction where the value was defined, if any.

source

pub fn unwrap_block(&self) -> Block

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

source

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.
