NAME¶

std::experimental::simd_mask::copy_from - std::experimental::simd_mask::copy_from

Synopsis¶

template<class Flags> (parallelism TS v2)
void copy_from( const bool* mem, Flags flags );

The load function replaces all elements of a simd_mask such that the i-th element is
assigned with mem[i] for all i in the range of [0, size()).

Parameters¶

mem - a pointer into an array where [mem, mem + size()) is a valid range
flags - if of type vector_aligned_tag, the load constructor may assume mem to point
to storage aligned by memory_alignment_v<simd_mask>

Type requirements¶

-
is_simd_flag_type_v<Flags> must be true.
