Implementations§

source§

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().

source

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");
source

pub fn is_overloaded(&self) -> bool

Check if specified intrinsic is overloaded

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

source

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");
