Variants

Mul

Format: mul rd, rs1, rs2

Description: performs an 32-bit 32-bit multiplication of signed rs1 by signed rs2 and places the lower 32 bits in the destination register. Implementation: x[rd] = x[rs1] * x[rs2]

Mulh

Format: mulh rd, rs1, rs2

Description: performs an 32-bit 32-bit multiplication of signed rs1 by signed rs2 and places the upper 32 bits in the destination register. Implementation: x[rd] = (x[rs1] * x[rs2]) >> 32

Mulhsu

Format: mulhsu rd, rs1, rs2

Description: performs an 32-bit 32-bit multiplication of signed rs1 by unsigned rs2 and places the upper 32 bits in the destination register. Implementation: x[rd] = (x[rs1] * x[rs2]) >> 32

Mulhu

Format: mulhu rd, rs1, rs2

Description: performs an 32-bit 32-bit multiplication of unsigned rs1 by unsigned rs2 and places the upper 32 bits in the destination register. Implementation: x[rd] = (x[rs1] * x[rs2]) >> 32

Div

Format: div rd, rs1, rs2

Description: perform an 32 bits by 32 bits signed integer division of rs1 by rs2, rounding towards zero Implementation: x[rd] = x[rs1] /s x[rs2]

Divu

Format: divu rd, rs1, rs2

Description: performs an 32 bits by 32 bits unsigned integer division of rs1 by rs2, rounding towards zero. Implementation: x[rd] = x[rs1] /u x[rs2]

Rem

Format: rem rd, rs1, rs2

Description: performs an 32 bits by 32 bits signed integer reminder of rs1 by rs2. Implementation: x[rd] = x[rs1] %s x[rs2]

Remu

Format: remu rd, rs1, rs2

Description: performs an 32 bits by 32 bits unsigned integer reminder of rs1 by rs2. Implementation: x[rd] = x[rs1] %u x[rs2]

Trait Implementations

impl Clone for MInstruction

fn clone(&self) -> MInstruction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MInstruction

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

Formats the value using the given formatter.

impl Default for MInstruction

fn default() -> MInstruction

Returns the “default value” for a type.

impl Display for MInstruction

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

Formats the value using the given formatter.

impl EnumCount for MInstruction

const COUNT: usize = 8usize

impl Hash for MInstruction

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 IntoEnumIterator for MInstruction

type Iterator = MInstructionIter

fn iter() -> MInstructionIter

impl Ord for MInstruction

fn cmp(&self, other: &MInstruction) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<MInstruction> for MInstruction

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

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

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

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

impl PartialOrd<MInstruction> for MInstruction

fn partial_cmp(&self, other: &MInstruction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
