(parallelism TS v2) | |
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.
