Batch of conditions¶
-
template<class T, class A = default_arch>
class xsimd::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 register_type = typename base_type::register_type¶
SIMD register type abstracted by this batch.
Public Functions
-
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
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
andy
.- 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.
