Struct ScalableVectorType

Source

pub struct ScalableVectorType<'ctx> { /* private fields */ }

Expand description

A ScalableVectorType is the type of a scalable multiple value SIMD constant or variable.

Implementations§

Source §

impl<'ctx> ScalableVectorType<'ctx>

Source

pub unsafe fn new(scalable_vector_type: LLVMTypeRef) -> Self

Create ScalableVectorType from LLVMTypeRef

§Safety

Undefined behavior, if referenced type isn’t scalable vector type

Source

pub fn size_of(self) -> Option<IntValue<'ctx>>

Gets the size of this ScalableVectorType. Value may vary depending on the target architecture.

§Example

use inkwell::context::Context;

let context = Context::create();
let f32_type = context.f32_type();

assert_eq!(f32_scalable_vector_type.get_size(), 3);
assert_eq!(f32_scalable_vector_type.get_element_type().into_float_type(), f32_type);

Source

pub fn const_zero(self) -> ScalableVectorValue<'ctx>

Creates a constant zero value of this ScalableVectorType.

§Example

use inkwell::context::Context;

let context = Context::create();
let f32_type = context.f32_type();
let f32_scalable_vec_type = f32_type.scalable_vec_type(7);

Source

pub fn print_to_string(self) -> LLVMString

Print the definition of a ScalableVectorType to LLVMString.

Source

pub fn get_undef(self) -> ScalableVectorValue<'ctx>

Creates an undefined instance of a ScalableVectorType.

§Example

use inkwell::context::Context;
use inkwell::AddressSpace;

let context = Context::create();
let f32_type = context.f32_type();
let f32_scalable_vec_type = f32_type.scalable_vec_type(3);
let f32_scalable_vec_undef = f32_scalable_vec_type.get_undef();

assert!(f32_scalable_vec_undef.is_undef());

Source

pub fn get_poison(self) -> ScalableVectorValue<'ctx>

Creates a poison instance of a ScalableVectorType.

§Example

use inkwell::context::Context;
use inkwell::AddressSpace;

let context = Context::create();
let f32_type = context.f32_type();
let f32_scalable_vec_type = f32_type.scalable_vec_type(3);

assert!(f32_scalable_vec_poison.is_undef());

Source

pub fn get_element_type(self) -> BasicTypeEnum<'ctx>

Gets the element type of this ScalableVectorType.

§Example

use inkwell::context::Context;

let context = Context::create();
let f32_type = context.f32_type();
let f32_scalable_vector_type = f32_type.scalable_vec_type(3);

assert_eq!(f32_scalable_vector_type.get_size(), 3);
assert_eq!(f32_scalable_vector_type.get_element_type().into_float_type(), f32_type);

Source

pub fn ptr_type(self, address_space: AddressSpace) -> PointerType<'ctx>

👎Deprecated:

Starting from version 15.0, LLVM doesn’t differentiate between pointer types. Use Context::ptr_type instead.

Creates a PointerType with this ScalableVectorType for its element type.

§Example

use inkwell::context::Context;
use inkwell::AddressSpace;

let context = Context::create();
let f32_type = context.f32_type();
let f32_scalable_vec_type = f32_type.scalable_vec_type(3);
let f32_scalable_vec_ptr_type = f32_scalable_vec_type.ptr_type(AddressSpace::default());

#[cfg(feature = "typed-pointers")]
assert_eq!(f32_scalable_vec_ptr_type.get_element_type().into_scalable_vector_type(), f32_scalable_vec_type);

Source

pub fn fn_type( self, param_types: &[BasicMetadataTypeEnum<'ctx>], is_var_args: bool, ) -> FunctionType<'ctx>

Creates a FunctionType with this ScalableVectorType for its return type.

§Example

use inkwell::context::Context;

let context = Context::create();
let f32_type = context.f32_type();
let f32_scalable_vec_type = f32_type.scalable_vec_type(3);
let fn_type = f32_scalable_vec_type.fn_type(&[], false);

Source

pub fn array_type(self, size: u32) -> ArrayType<'ctx>

Creates an ArrayType with this ScalableVectorType for its element type.

§Example

use inkwell::context::Context;

let context = Context::create();
let f32_type = context.f32_type();
let f32_scalable_vec_type = f32_type.scalable_vec_type(3);
let f32_scalable_vec_array_type = f32_scalable_vec_type.array_type(3);

assert_eq!(f32_scalable_vec_array_type.len(), 3);
assert_eq!(f32_scalable_vec_array_type.get_element_type().into_scalable_vector_type(), f32_scalable_vec_type);

Source

pub fn const_array( self, values: &[ScalableVectorValue<'ctx>], ) -> ArrayValue<'ctx>

Creates a constant ArrayValue.

§Example

use inkwell::context::Context;
use inkwell::types::ScalableVectorType;

let context = Context::create();
let f32_type = context.f32_type();
