Struct cranelift_codegen::MachLabel

source ·
pub struct MachLabel(/* private fields */);
Expand description

A label refers to some offset in a MachBuffer. It may not be resolved at the point at which it is used by emitted code; the buffer records “fixups” for references to the label, and will come back and patch the code appropriately when the label’s location is eventually known.

Implementations§

source§

impl MachLabel

source

pub fn from_u32(x: u32) -> Self

Create a new instance from a u32.

source

pub fn as_u32(self) -> u32

Return the underlying index value as a u32.

source

pub fn as_bits(self) -> u32

Return the raw bit encoding for this instance.

source

pub fn from_bits(x: u32) -> Self

Create a new instance from the raw bit encoding.

source§

impl MachLabel

source

pub fn from_block(bindex: Block) -> MachLabel

source

pub fn get(self) -> u32

source

pub fn to_string(&self) -> String

Creates a string representing this label, for convenience.
