Struct Fence 

pub struct Fence {
    pub fm: u8,
    pub pred: FenceSet,
    pub succ: FenceSet,
    pub dest: Reg,
    pub src: Reg,
}

The details of a RISC-V fence instruction.

Fields

fm: u8

The fm field of the instruction.

• 0b0000 is a normal fence
• 0b1000 with rw,rw implies a fence.tso

pred: FenceSet

The predecessor set.

succ: FenceSet

The sucessor set.

dest: Reg

The rd field of the instruction. Currently always zero.

src: Reg

The rs1 field of the instruction. Currently always zero.

Implementations

impl Fence

pub fn is_tso(&self) -> bool

Whether this is a fence.tso. fm=0b1000 and RW,RW

pub fn is_pause(&self) -> bool

Whether this fence indicates a pause assembler pseudoinstruction.

Trait Implementations

impl Clone for Fence

fn clone(&self) -> Fence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hash for Fence

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Fence

fn eq(&self, other: &Fence) -> 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.
