Data type compatibility with NEON intrinsics

Question

I am working on ARM optimizations using the NEON intrinsics, from C++ code. I understand and master most of the typing issues, but I am stuck on this one:

The instru

Answer 1

I was facing the same kind of problem, so I introduced a flexible data type.

I can now therefore define the following:

typedef NeonVectorType uint_128bit_t; //suitable for uint8x16_t, uint8x8x2_t, uint32x4_t, etc.
typedef NeonVectorType uint_64bit_t; //suitable for uint8x8_t, uint32x2_t, etc.
