Namespaces

namespace	ein::detail

Concepts
concept	ein::has_storage_type
concept	ein::has_lifted_operations
	Does this type have operations that semantically correct when lifted to the simd_data_t level?
concept	ein::has_simd_type
	ein::simd_data_t<T,N> is defined
concept	ein::has_builtin_convertvector
	can we convert simd_data_t<U,N> -> simd_data_t<T,N> automatically using gcc vector extensions?
concept	ein::simd_builtin
	is this type one of the types that is handed well automatically by clang/gcc vector extensions?
concept	ein::has_mmask
	Do we want to use AVX512's notion of an _mmask8, _mmask16, _mmask32, or _mmask64 for masking operations.

Typedefs
template<typename T >
using	ein::storage_type
	The type used to store T in a simd_data_t.
template<typename T , size_t N>
using	ein::simd_data_t = storage_type<T> __attribute__((__vector_size__(N*sizeof(storage_type<T>)),__aligned__(N*sizeof(storage_type<T>))))
template<typename T , size_t N>
using	ein::simd_intrinsic_t
	Returns the Intel intrinsic type associated with a simd register full of N values of type T.
template<size_t N>
using	ein::mmask_t
	If AVX512 is enabled returns the type of an n-bit mmask.
template<typename T , size_t N>
using	ein::simd_mask_t
	What type of mask should I use?
