Enum AmoOp 

pub enum AmoOp {
    Swap,
    Add,
    Xor,
    And,
    Or,
    Min,
    Max,
    Minu,
    Maxu,
}

Selects an atomic operation while one instruction form supplies the common operands.

The A extension gives all AMOs the same address, source, destination, and width fields. A small enum avoids duplicate NNIL variants for that common structure.

Variants

Swap

Stores the source value without combining it with the loaded value.

Add

Stores the wrapping sum of the loaded and source values.

Xor

Stores the bitwise exclusive OR of both values.

And

Stores the bitwise AND of both values.

Or

Stores the bitwise OR of both values.

Min

Stores the smaller signed value.

Max

Stores the larger signed value.

Minu

Stores the smaller unsigned value.

Maxu

Stores the larger unsigned value.

Trait Implementations

impl Clone for AmoOp

fn clone(&self) -> AmoOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AmoOp

impl Debug for AmoOp

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

Formats the value using the given formatter.

impl Eq for AmoOp

impl PartialEq for AmoOp

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