Enum PointerWidth 

#[non_exhaustive]
pub enum PointerWidth {
    P32,
    P64,
}

The width of addresses (ptr and ref) in a module.

Examples

use ir_lang::PointerWidth;

assert_eq!(PointerWidth::P64.bytes(), 8);
assert_eq!(PointerWidth::P32.bits(), 32);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

P32

32-bit addresses (wasm32, 32-bit targets).

P64

64-bit addresses (x86-64, AArch64, riscv64). The default.

Implementations

impl PointerWidth

pub const fn bytes(self) -> u32

The address width in bytes.

Examples

use ir_lang::PointerWidth;

assert_eq!(PointerWidth::P32.bytes(), 4);

pub const fn bits(self) -> u32

The address width in bits.

Examples

use ir_lang::PointerWidth;

assert_eq!(PointerWidth::P64.bits(), 64);

pub const fn is_address_int(self, ty: Type) -> bool

Whether ty is an integer exactly as wide as an address (the integer side of ptr_to_int / int_to_ptr).

Examples

use ir_lang::{PointerWidth, Type};

assert!(PointerWidth::P64.is_address_int(Type::U64));
assert!(!PointerWidth::P64.is_address_int(Type::U32));
