Struct Uniform

pub(crate) struct Uniform {
    pub unit: Reg,
    pub total: Size,
    pub is_consecutive: bool,
}

An argument passed entirely registers with the same kind (e.g., HFA / HVA on PPC64 and AArch64).

Fields

unit: Reg

total: Size

The total size of the argument, which can be:

• equal to unit.size (one scalar/vector),
• a multiple of unit.size (an array of scalar/vectors),
• if unit.kind is Integer, the last element can be shorter, i.e., { i64, i64, i32 } for 64-bit integers with a total size of 20 bytes. When the argument is actually passed, this size will be rounded up to the nearest multiple of unit.size.

is_consecutive: bool

Indicate that the argument is consecutive, in the sense that either all values need to be passed in register, or all on the stack. If they are passed on the stack, there should be no additional padding between elements.

Implementations

impl Uniform

pub fn align<C>(&self, cx: &C) -> Align

where C: HasDataLayout,

pub fn new(unit: Reg, total: Size) -> Uniform

Pass using one or more values of the given type, without requiring them to be consecutive. That is, some values may be passed in register and some on the stack.

pub fn consecutive(unit: Reg, total: Size) -> Uniform

Pass using one or more consecutive values of the given type. Either all values will be passed in registers, or all on the stack.

Trait Implementations

impl Clone for Uniform

fn clone(&self) -> Uniform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Uniform

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

Formats the value using the given formatter.

impl From<Reg> for Uniform

fn from(unit: Reg) -> Uniform

Converts to this type from the input type.

impl From<Uniform> for CastTarget

fn from(uniform: Uniform) -> CastTarget

Converts to this type from the input type.

impl Hash for Uniform

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<__CTX> HashStable<__CTX> for Uniform

where __CTX: HashStableContext,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl PartialEq for Uniform

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Uniform

impl Eq for Uniform

impl StructuralPartialEq for Uniform

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
