Struct llhd::Function

pub struct Function { /* fields omitted */ }

A function. Sequentially executes instructions to determine a result value from its inputs. Implements control flow and immediate execution.

Methods

impl Function

pub fn new(     name: impl Into<String>,     ty: Type ) -> Function

Create a new function with the given name and type signature. Anonymous arguments are created for each argument in the type signature. Use the args_mut function to get a hold of these arguments and assign names and additional data to them.

pub fn as_ref(&self) -> FunctionRef

Obtain a reference to this function.

pub fn name(&self) -> &str

Get the name of the function.

pub fn return_ty(&self) -> &Type

Get the return type of the function.

pub fn arg(&self, idx: usize) -> ArgumentRef

Get a graph reference to one of the arguments of the function.

pub fn args(&self) -> &[Argument]

Get a reference to the arguments of the function.

pub fn args_mut(&mut self) -> &mut [Argument]

Get a mutable reference to the arguments of the function.

pub fn body(&self) -> &SeqBody

Get a reference to the sequential body of the function.

pub fn body_mut(&mut self) -> &mut SeqBody

Get a mutable reference to the sequential body of the function.

Trait Implementations

impl Value for Function

fn id(&self) -> ValueId

Get the unique ID of the value.

fn ty(&self) -> Type

Get the type of the value.

fn name(&self) -> Option<&str>

Get the optional name of the value.

fn is_global(&self) -> bool

Whether this value is global or not. Global values are considered during linking, and are visible in a module's symbol table. Local values are not, and are only visible within the surrounding context (module or unit).
