std::experimental::simd_mask<T,Abi>::copy_from - cppreference.com (original) (raw)
| template<class Flags> void copy_from( const bool* mem, Flags flags ); | | (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()).
[edit] 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 must be true. |
