E.g. An interleaved load (Factor = 2):
%wide.vec = load <8 x i32>, <8 x i32>* %ptr
%v0 = shuffle <8 x i32> %wide.vec, <8 x i32> undef, <0, 2, 4, 6>
%v1 = shuffle <8 x i32> %wide.vec, <8 x i32> undef, <1, 3, 5, 7>
It can be transformed into a ld2 intrinsic in AArch64 backend or a vld2 intrinsic in ARM backend.
E.g. An interleaved store (Factor = 3):
%i.vec = shuffle <8 x i32> %v0, <8 x i32> %v1, <0, 4, 8, 1, 5, 9, 2, 6, 10, 3, 7, 11>
store <12 x i32> %i.vec, <12 x i32>* %ptr
It can be transformed into a st3 intrinsic in AArch64 backend or a vst3 intrinsic in ARM backend.
