Implementations§

§

impl VectorSize

pub fn from_lane_size(size: ScalarSize, is_128bit: bool) -> VectorSize

Get the vector operand size with the given scalar size as lane size.

pub fn operand_size(&self) -> OperandSize

Get the integer operand size that corresponds to a lane of a vector with a certain size.

pub fn lane_size(&self) -> ScalarSize

Get the scalar operand size that corresponds to a lane of a vector with a certain size.

pub fn is_128bits(&self) -> bool

Returns true if the VectorSize is 128-bits.

pub fn enc_size(&self) -> (u32, u32)

Return the encoding bits that are used by some SIMD instructions for a particular operand size.

pub fn enc_float_size(&self) -> u32

Return the encoding bit that is used by some floating-point SIMD instructions for a particular operand size.
