Struct Gpr

pub struct Gpr<R: AsReg = u8>(/* private fields */);

A general purpose x64 register (e.g., %rax).

This container wraps true register type R to allow users to specify their own; by default this will use u8.

Implementations

impl<R: AsReg> Gpr<R>

pub fn new(reg: R) -> Self

Create a Gpr that may be real (immediately emit-able in machine code) or virtual (waiting for register allocation).

pub fn enc(&self) -> u8

Return the register’s hardware encoding; the underlying type R must be a real register at this point.

Panics

Panics if the register is not a valid x64 register.

pub fn to_string(&self, size: Size) -> String

Return the register name at the given size.

Trait Implementations

impl<'a, R: AsReg> Arbitrary<'a> for Gpr<R>

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>
