Struct inkwell::intrinsics::Intrinsic

pub struct Intrinsic { /* private fields */ }

Implementations

impl Intrinsic

A wrapper around LLVM intrinsic id

To call it you would need to create a declaration inside a module using Self::get_declaration().

pub fn find(name: &str) -> Option<Self>

Find llvm intrinsic id from name

Example

use inkwell::{intrinsics::Intrinsic, context::Context};

let trap_intrinsic = Intrinsic::find("llvm.trap").unwrap();

let context = Context::create();
let module = context.create_module("trap");
let builder = context.create_builder();
let void_type = context.void_type();
let fn_type = void_type.fn_type(&[], false);
let fn_value = module.add_function("trap", fn_type, None);
let entry = context.append_basic_block(fn_value, "entry");

let trap_function = trap_intrinsic.get_declaration(&module, &[]).unwrap();

builder.position_at_end(entry);
builder.build_call(trap_function, &[], "trap_call");

pub fn is_overloaded(&self) -> bool

Check if specified intrinsic is overloaded

Overloaded intrinsics need some argument types to be specified to declare them

pub fn get_declaration<'ctx>( &self, module: &Module<'ctx>, param_types: &[BasicTypeEnum<'_>] ) -> Option<FunctionValue<'ctx>>

Create or insert the declaration of an intrinsic.

For overloaded intrinsics, parameter types must be provided to uniquely identify an overload.

Example

use inkwell::{intrinsics::Intrinsic, context::Context};

let trap_intrinsic = Intrinsic::find("llvm.trap").unwrap();

let context = Context::create();
let module = context.create_module("trap");
let builder = context.create_builder();
let void_type = context.void_type();
let fn_type = void_type.fn_type(&[], false);
let fn_value = module.add_function("trap", fn_type, None);
let entry = context.append_basic_block(fn_value, "entry");

let trap_function = trap_intrinsic.get_declaration(&module, &[]).unwrap();

builder.position_at_end(entry);
builder.build_call(trap_function, &[], "trap_call");

Trait Implementations

impl Clone for Intrinsic

fn clone(&self) -> Intrinsic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Intrinsic

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

Formats the value using the given formatter.

impl PartialEq for Intrinsic

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