Enum BranchTarget

pub enum BranchTarget {
    Label(MachLabel),
    ResolvedOffset(i32),
}

A branch target. Either unresolved (basic-block index) or resolved (offset from end of current instruction).

Variants

Label(MachLabel)

An unresolved reference to a Label, as passed into lower_branch_group().

ResolvedOffset(i32)

A fixed PC offset.

Implementations

impl BranchTarget

pub fn as_label(self) -> Option<MachLabel>

Return the target’s label, if it is a label-based target.

pub fn as_offset14_or_zero(self) -> u32

Return the target’s offset, if specified, or zero if label-based.

pub fn as_offset19_or_zero(self) -> u32

Return the target’s offset, if specified, or zero if label-based.

pub fn as_offset26_or_zero(self) -> u32

Return the target’s offset, if specified, or zero if label-based.

Trait Implementations

impl Clone for BranchTarget

fn clone(&self) -> BranchTarget

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BranchTarget

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for BranchTarget

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
