[LLVMdev] [AArch64] Should we restrict to the pointer type used in ldN/stN intrinsics?
...p0v4i32' or
'xx.ld2.v4i32.p0i8', which looks confusing. Should we modify the definition
of such intrinsics and restrict the pointer type?
If you agree with me, I suggest to use a pointer type to the vector element.
Because the 'arm_neon.h' declare the ld2 intrinsic like 'int32x2x2_t
vld2_s32(int32_t const * ptr)', which also uses a pointer to the vector
element. To achieve this is easy, I have a patch to add a constraint
'PointerToVectorElt' in 'intrinsics.td'. I just wonder if such modification
is reasonable.
Thanks,
