Function padlow¶
function padlow(const vec<T, N> &) simd¶
template <size_t Ncount, typename T, size_t N>
KFR_INTRINSIC vec<T, N + Ncount> padlow(const vec<T, N>& x)Pads x with Ncount zero-initialized lanes on the low side.
| Ncount | Number of lanes to prepend. |
| T | Element type of the vector. |
| N | Input vector length. |
| x | Source vector. |
A vector of length N + Ncount with the prepended lanes zeroed. |

Function padlow¶
function padlow(const vec<T, N> &, std::type_identity_t<T>) simd¶
template <size_t Ncount, typename T, size_t N>
KFR_INTRINSIC vec<T, N + Ncount> padlow(const vec<T, N>& x, std::type_identity_t<T> newvalue)Pads x with Ncount copies of newvalue on the low side.
| Ncount | Number of lanes to prepend. |
| T | Element type of the vector. |
| N | Input vector length. |
| x | Source vector. |
| newvalue | Value to fill the prepended lanes with. |
A vector of length N + Ncount with the prepended lanes set to newvalue. |
