Struct cranelift_codegen_meta::cdsl::types::DynamicVectorType

pub(crate) struct DynamicVectorType {
    base: LaneType,
    unscaled_lanes: u64,
}

A concrete dynamic SIMD vector type.

A vector type has a lane type which is an instance of LaneType, and a positive number of lanes.

Fields

base: LaneType

unscaled_lanes: u64

Implementations

impl DynamicVectorType

pub fn new(base: LaneType, unscaled_lanes: u64) -> Self

Initialize a new type with base lane type and a minimum number of lanes.

pub fn doc(&self) -> String

Return a string containing the documentation comment for this vector type.

pub fn lane_bits(&self) -> u64

Return the number of bits in a lane.

pub fn minimum_lane_count(&self) -> u64

Return the number of lanes.

pub fn lane_type(&self) -> LaneType

Return the lane type.

pub fn number(&self) -> u16

Find the unique number associated with this vector type.

Dynamic vector types are encoded in the same manner as VectorType, with lane type in the low 4 bits and the log2(lane_count). We add the VECTOR_BASE to move these numbers into the range beyond the fixed SIMD types.

Trait Implementations

impl Clone for DynamicVectorType

fn clone(&self) -> DynamicVectorType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicVectorType

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

Formats the value using the given formatter.

impl Display for DynamicVectorType

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

Formats the value using the given formatter.

impl From<DynamicVectorType> for ValueType

Create a ValueType from a given dynamic vector type.

fn from(vector: DynamicVectorType) -> Self

Converts to this type from the input type.

impl Hash for DynamicVectorType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DynamicVectorType

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