Struct cranelift_codegen::isa::aarch64::inst::imms::ImmLogic

pub struct ImmLogic {
    pub n: bool,
    pub r: u8,
    pub s: u8,
    pub size: OperandSize,
    /* private fields */
}

An immediate for logical instructions.

Fields

n: bool

N flag.

r: u8

S field: element size and element bits.

s: u8

R field: rotate amount.

size: OperandSize

Was this constructed for a 32-bit or 64-bit instruction?

Implementations

impl ImmLogic

pub fn maybe_from_u64(value: u64, ty: Type) -> Option<ImmLogic>

Compute an ImmLogic from raw bits, if possible.

pub fn enc_bits(&self) -> u32

Returns bits ready for encoding: (N:1, R:6, S:6)

pub fn value(&self) -> u64

Returns the value that this immediate represents.

pub fn invert(&self) -> ImmLogic

Return an immediate for the bitwise-inverted value.

Trait Implementations

impl Clone for ImmLogic

fn clone(&self) -> ImmLogic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImmLogic

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

Formats the value using the given formatter.

impl PartialEq for ImmLogic

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