Concept definition

template<typename Ta, typename Ty, uint32_t N1, uint32_t N2>
concept gpu::xetla::xetla_matrix_ref =  __ESIMD_NS::detail::is_simd_view_type_v<Ta> && std::is_same_v<
                  typename Ta::element_type, native_type_t<Ty>> &&(N1
                  == __ESIMD_NS::shape_type<Ta>::type::Size_y)

Detailed Description

Workaround for ESIMD matrix(2D) ref type.

Use C++20 concept to constrains the scope of auto.

Note

Need to be used together with __REF__, i.e. "xetla_matrix_ref __REF__" is the full declaration of xetla matrix reference.

Template Parameters

Ta	first tparam is reserved for auto.
Ty	data type in xetla_matrix_ref.
N1	row num in xetla_matrix_ref.
N2	col num in xetla_matrix_ref.
