Enum OperandSize

pub enum OperandSize {
    Size32,
    Size64,
}
Expand description

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>(bits: I) -> OperandSize
where I: Into<usize>,

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.
