Struct AmodeOffsetPlusKnownOffset

pub struct AmodeOffsetPlusKnownOffset {
    pub simm32: AmodeOffset,
    pub offset: Option<KnownOffset>,
}

An AmodeOffset immediate with an optional known offset.

Cranelift does not know certain offsets until emission time. To accommodate Cranelift, this structure stores an optional KnownOffset. The following happens immediately before emission:

• the KnownOffset is looked up, mapping it to an offset value
• the [Simm32] value is added to the offset value

Fields

simm32: AmodeOffset

offset: Option<KnownOffset>

Implementations

impl AmodeOffsetPlusKnownOffset

pub const ZERO: AmodeOffsetPlusKnownOffset

pub fn value(&self, sink: &impl CodeSink) -> i32

Panics

Panics if the sum of the immediate and the known offset value overflows.

Trait Implementations

impl Arbitrary<'_> for AmodeOffsetPlusKnownOffset

fn arbitrary(u: &mut Unstructured<'_>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

impl Clone for AmodeOffsetPlusKnownOffset

fn clone(&self) -> AmodeOffsetPlusKnownOffset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AmodeOffsetPlusKnownOffset

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

Formats the value using the given formatter.

impl LowerHex for AmodeOffsetPlusKnownOffset

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

impl PartialEq for AmodeOffsetPlusKnownOffset

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

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

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

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