Struct cranelift_codegen::isa::aarch64::inst::imms::MoveWideConst

pub struct MoveWideConst {
    pub bits: u16,
    pub shift: u8,
}

A 16-bit immediate for a MOVZ instruction, with a {0,16,32,48}-bit shift.

Fields

bits: u16

The value.

shift: u8

Result is bits shifted 16*shift bits to the left.

Implementations

impl MoveWideConst

pub fn maybe_from_u64(value: u64) -> Option<MoveWideConst>

pub fn maybe_with_shift(imm: u16, shift: u8) -> Option<MoveWideConst>

Create a MoveWideCosnt from a given shift, if possible.

pub fn zero() -> MoveWideConst

Create a zero immediate of this format.
