Struct cranelift_codegen::ir::AbiParam

pub struct AbiParam {
    pub value_type: Type,
    pub purpose: ArgumentPurpose,
    pub extension: ArgumentExtension,
    pub legalized_to_pointer: bool,
}

Function parameter or return value descriptor.

This describes the value type being passed to or from a function along with flags that affect how the argument is passed.

Fields

value_type: Type

Type of the argument value.

purpose: ArgumentPurpose

Special purpose of argument, or Normal.

extension: ArgumentExtension

Method for extending argument to a full register.

legalized_to_pointer: bool

Was the argument converted to pointer during legalization?

Implementations

impl AbiParam

pub fn new(vt: Type) -> Self

Create a parameter with default flags.

pub fn special(vt: Type, purpose: ArgumentPurpose) -> Self

Create a special-purpose parameter that is not (yet) bound to a specific register.

pub fn uext(self) -> Self

Convert self to a parameter with the uext flag set.

pub fn sext(self) -> Self

Convert self to a parameter type with the sext flag set.

Trait Implementations

impl Clone for AbiParam

fn clone(&self) -> AbiParam

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AbiParam

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

Formats the value using the given formatter.

impl Display for AbiParam

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

Formats the value using the given formatter.

impl Hash for AbiParam

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<AbiParam> for AbiParam

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