Batch of conditions

template<class T, class A = default_arch>
class batch_bool : public types::get_bool_simd_register_t<T, default_arch>

batch of predicate over scalar or complex values.

Abstract representation of a predicate over SIMD register for scalar or complex values.

Template Parameters:

• T – the type of the predicated values.

• A – the architecture this batch is tied too.

Public Types

using value_type = bool

Type of the scalar elements within this batch.

using arch_type = A

SIMD Architecture abstracted by this batch.

using register_type = typename base_type::register_type

SIMD register type abstracted by this batch.

using batch_type = batch<T, A>

Associated batch type this batch represents logical operations for.

Public Functions

inline batch_bool() = default

Create a batch initialized with undefined values.

inline uint64_t mask() const noexcept

Extract a scalar mask representation from this batch_bool.

Returns:

bit mask

Public Static Functions

static inline batch_bool from_mask(uint64_t mask) noexcept

Extract a scalar mask representation from this batch_bool.

Returns:

bit mask

Public Static Attributes

static constexpr std::size_t size = sizeof(types::simd_register<T, A>) / sizeof(T)

Number of scalar elements in this batch.

Logical operators

template<class T, class A>
inline batch_bool<T, A> bitwise_andnot(batch_bool<T, A> const &x, batch_bool<T, A> const &y) noexcept

Computes the bitwise and not of batches x and y.

Parameters:

• x – batch involved in the operation.

• y – batch involved in the operation.

Returns:

the result of the bitwise and not.

Reducers

template<class T, class A>
inline bool all(batch_bool<T, A> const &x) noexcept

Returns true if all the boolean values in the batch are true, false otherwise.

Parameters:

x – the batch to reduce.

Returns:

a boolean scalar.

template<class T, class A>
inline bool any(batch_bool<T, A> const &x) noexcept

Return true if any of the boolean values in the batch is true, false otherwise.

Parameters:

x – the batch to reduce.

Returns:

a boolean scalar.

template<class T, class A>
inline bool none(batch_bool<T, A> const &x) noexcept

Return true if none of the boolean values in the batch is true, false otherwise.

Parameters:

x – the batch to reduce.

Returns:

a boolean scalar.
