Struct cranelift_codegen::ir::AbiParam

pub struct AbiParam {
    pub value_type: Type,
    pub purpose: ArgumentPurpose,
    pub extension: ArgumentExtension,
    pub location: ArgumentLoc,
    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.

location: ArgumentLoc

ABI-specific location of this argument, or Unassigned for arguments that have not yet been legalized.

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 special_reg(vt: Type, purpose: ArgumentPurpose, regunit: RegUnit) -> Self

Create a parameter for a special-purpose 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.

pub fn display<'a, R: Into<Option<&'a RegInfo>>>(
    &'a self,
    regs: R
) -> DisplayAbiParam<'a>

Return an object that can display self with correct register names.

Trait Implementations
