Struct framehop::aarch64::UnwindRegsAarch64

pub struct UnwindRegsAarch64 { /* private fields */ }

The registers used for unwinding on Aarch64. We only need lr (x30), sp (x31), and fp (x29).

We also have a PtrAuthMask which allows stripping off the pointer authentication hash bits from the return address when unwinding through libraries which use pointer authentication, e.g. in system libraries on macOS.

Implementations

impl UnwindRegsAarch64

pub fn new(lr: u64, sp: u64, fp: u64) -> Self

Create a set of unwind register values and do not apply any pointer authentication stripping.

pub fn new_with_ptr_auth_mask( code_ptr_auth_mask: PtrAuthMask, lr: u64, sp: u64, fp: u64 ) -> Self

Create a set of unwind register values with the given mask for return address pointer authentication stripping.

pub fn lr_mask(&self) -> PtrAuthMask

Get the PtrAuthMask which we apply to the lr value.

pub fn sp(&self) -> u64

Get the stack pointer value.

pub fn set_sp(&mut self, sp: u64)

Set the stack pointer value.

pub fn fp(&self) -> u64

Get the frame pointer value (x29).

pub fn set_fp(&mut self, fp: u64)

Set the frame pointer value (x29).

pub fn lr(&self) -> u64

Get the lr register value.

pub fn set_lr(&mut self, lr: u64)

Set the lr register value.

Trait Implementations

impl Clone for UnwindRegsAarch64

fn clone(&self) -> UnwindRegsAarch64

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnwindRegsAarch64

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

Formats the value using the given formatter.

impl PartialEq for UnwindRegsAarch64

fn eq(&self, other: &UnwindRegsAarch64) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
