Enum cranelift_codegen::isa::aarch64::inst::args::OperandSize

pub enum OperandSize {
    Size32,
    Size64,
}

Type used to communicate the operand size of a machine instruction, as AArch64 has 32- and 64-bit variants of many instructions (and integer registers).

Variants

Size32

32-bit.

Size64

64-bit.

Implementations

impl OperandSize

pub fn is32(self) -> bool

32-bit case?

pub fn is64(self) -> bool

64-bit case?

pub fn from_bits<I: Into<usize>>(bits: I) -> OperandSize

Convert from a needed width to the smallest size that fits.

pub fn bits(&self) -> u8

Return the operand size in bits.

pub fn from_ty(ty: Type) -> OperandSize

Convert from an integer type into the smallest size that fits.

pub fn to_ty(self) -> Type

Convert to I32, I64, or I128.

pub fn sf_bit(&self) -> u32

Register interpretation bit. When 0, the register is interpreted as the 32-bit version. When 1, the register is interpreted as the 64-bit version.

pub fn max_value(&self) -> u64

The maximum unsigned value representable in a value of this size.

Trait Implementations

impl Clone for OperandSize

fn clone(&self) -> OperandSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OperandSize

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

Formats the value using the given formatter.

impl PartialEq for OperandSize

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