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) -> &str

Return the register name at the given size.

Trait Implementations

impl<R: AsReg> AsMut<R> for Gpr<R>

fn as_mut(&mut self) -> &mut R

Converts this type into a mutable reference of the (usually inferred) input type.

impl<R: AsReg> AsRef<R> for Gpr<R>

fn as_ref(&self) -> &R

Converts this type into a shared reference of the (usually inferred) input type.

impl<R: Clone + AsReg> Clone for Gpr<R>

fn clone(&self) -> Gpr<R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<R: Debug + AsReg> Debug for Gpr<R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<R: Copy + AsReg> Copy for Gpr<R>
