Enum cranelift_codegen::ir::ArgumentExtension

pub enum ArgumentExtension {
    None,
    Uext,
    Sext,
}

Function argument extension options.

On some architectures, small integer function arguments are extended to the width of a general-purpose register.

Variants

None

No extension, high bits are indeterminate.

Uext

Unsigned extension: high bits in register are 0.

Sext

Signed extension: high bits in register replicate sign bit.

Trait Implementations

impl Clone for ArgumentExtension

fn clone(&self) -> ArgumentExtension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArgumentExtension

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

Formats the value using the given formatter.

impl Hash for ArgumentExtension

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<ArgumentExtension> for ArgumentExtension

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