Struct Flags

pub struct Flags { /* private fields */ }
Expand description

Flags group arm64.

Implementations§

§

impl Flags

pub fn new(shared: &Flags, builder: &Builder) -> Flags

Create flags arm64 settings group.

§

impl Flags

pub fn iter(&self) -> impl Iterator<Item = Value>

Iterates the setting values.

§

impl Flags

User-defined settings.

pub fn predicate_view(&self) -> PredicateView<'_>

Get a view of the boolean predicates.

pub fn has_lse(&self) -> bool

Has Large System Extensions (FEAT_LSE) support.

pub fn has_pauth(&self) -> bool

Has Pointer authentication (FEAT_PAuth) support; enables the use of non-HINT instructions, but does not have an effect on code generation by itself.

pub fn has_fp16(&self) -> bool

Use half-precision floating point (FEAT_FP16) instructions.

pub fn sign_return_address_all(&self) -> bool

If function return address signing is enabled, then apply it to all functions; does not have an effect on code generation by itself.

pub fn sign_return_address(&self) -> bool

Use pointer authentication instructions to sign function return addresses; HINT-space instructions using the A key are generated and simple functions that do not use the stack are not affected unless overridden by other settings.

pub fn sign_return_address_with_bkey(&self) -> bool

Use the B key with pointer authentication instructions instead of the default A key; does not have an effect on code generation by itself. Some platform ABIs may require this, for example.

pub fn use_bti(&self) -> bool

Use Branch Target Identification (FEAT_BTI) instructions.
