Struct cranelift_codegen::ir::immediates::Offset32

pub struct Offset32(_);

32-bit signed immediate offset.

This is used to encode an immediate offset for load/store instructions. All supported ISAs have a maximum load/store offset that fits in an i32.

Methods

impl Offset32

pub fn new(x: i32) -> Self

Create a new Offset32 representing the signed number x.

pub fn try_from_i64(x: i64) -> Option<Self>

Create a new Offset32 representing the signed number x if possible.

pub fn try_add_i64(self, x: i64) -> Option<Self>

Add in the signed number x if possible.
