Enum cranelift_codegen::machinst::MachTerminator

pub enum MachTerminator<'a> {
    None,
    Ret,
    Uncond(MachLabel),
    Cond(MachLabel, MachLabel),
    Indirect(&'a [MachLabel]),
}

Describes a block terminator (not call) in the vcode, when its branches have not yet been finalized (so a branch may have two targets).

Variants

None

Not a terminator.

Ret

A return instruction.

Uncond(MachLabel)

An unconditional branch to another block.

Cond(MachLabel, MachLabel)

A conditional branch to one of two other blocks.

Indirect(&'a [MachLabel])

An indirect branch with known possible targets.

Implementations

impl<'a> MachTerminator<'a>

pub fn get_succs(&self) -> SmallVec<[MachLabel; 2]>

Get the successor labels named in a MachTerminator.

pub fn is_term(&self) -> bool

Is this a terminator?

Trait Implementations

impl<'a> Clone for MachTerminator<'a>

fn clone(&self) -> MachTerminator<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for MachTerminator<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq<MachTerminator<'a>> for MachTerminator<'a>

fn eq(&self, other: &MachTerminator<'a>) -> bool

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

fn ne(&self, other: &MachTerminator<'a>) -> bool
