Detailed Description

Alignment type tags and related APIs for use with ESIMD memory access operations.

The basic restrictions for memory location specified as parameters for memory access APIs supporting alignment control are as follows:

• If alignment control parameter is element_aligned_tag, then the location must be aligned by alignof(T), where T is element type.
• If it is vector_aligned_tag, the location must be aligned by alignof(VT), where VT is the raw vector type of the accessed simd_obj_impl derivative class object.
• If it is overaligned_tag<N>, the location must be aligned by N.

Program not meeting alignment requirements results in undefined behavior.
