- Note
- use eve::broadcast or a constructor to create a simd_value from a scalar value. This is a shuffle, for when the value is in register already.
Defined in Header
#include <eve/module/core.hpp>
As any named shuffle, allows to pass a group size, to treat multiple elements as one. Group size has to be 0 < G <= T::size()
template <simd_value T, std::ptrdiff_t G, std::ptrdiff_t I>
template <simd_value T, std::ptrdiff_t I>
constexpr auto broadcast_lane
a named shuffle for duplicating the lane across a register.
Definition broadcast_lane.hpp:127
SIMD register cardinal type.
Definition cardinal.hpp:15
Parameters
- x - simd_value to shuffle
- G - (optional) - number of elements to treat as one.
- I - index of the lane to broadcast
(2) calls (1) with G == 1; (1) broadcasts the group of size G in position I to all register.
Return value
shuffled register
#include <eve/module/core.hpp>
#include <tts/tts.hpp>
int main()
{
w_t x {0, 1, 2, 3};
}
constexpr callable_all_ all
Computes a bool value which is true if and only if all elements of x are not zero.
