Description

template<typename T>
class gmx::internal::SimdArrayRef< T >

STL-like container for aligned SIMD type. Used as ArrayRef<SimdReal>.

Should provide the same interface as ArrayRef. Any missing functions should be added as needed. The pointer type (used e.g. for initialization) is a real pointer. The reference type (used e.g. for operator[] and iterator dereference) is SimdReference which executes the aligned load/store as is appropriate. For both iterator and element access, the access happens in blocks of SIMD width. Meaning that a[1] refers to the 2nd SIMD vector and thus reals 8-15 for 8-wide SIMD. The starting address has to be aligned and the length has to be multiple of the SIMD width.

Template Parameters

T	SIMD type (e.g. SimdReal)

Public Types
using	size_type = size_t
	Type for representing size of the container.

using	difference_type = std::ptrdiff_t
