Hi Richard,
> gcc/
> * config/arm/arm.c (arm_print_operand): Use MEM_SIZE to get the

> (T_DREG, T_QREG): New neon_builtin_type_bits.
> (arm_init_neon_builtins): Assert that the load and store operands
> are neon_struct_operands.
> (locate_neon_builtin_icode): Provide the neon_builtin_type_bits.
> (NEON_ARG_MEMORY): New builtin_arg.
> (neon_dereference_pointer): New function.
> (arm_expand_neon_args): Add a neon_builtin_type_bits argument.
> Handle NEON_ARG_MEMORY.
> (arm_expand_neon_builtin): Update after above interface changes.
> Use NEON_ARG_MEMORY for loads and stores.
> * config/arm/predicates.md (neon_struct_operand): New predicate.
> * config/arm/iterators.md (V_two_elem): Tweak formatting.
> (V_three_elem): Use BLKmode for accesses that have no associated mode.
> (V_four_elem): Tweak formatting.
> * config/arm/neon.md (neon_vld1<mode>, neon_vld1_dup<mode>)

> (neon_vst3qb<mode>, neon_vld4qa<mode>, neon_vld4qb<mode>)
> (neon_vst4qa<mode>, neon_vst4qb<mode>): Likewise, but halve

> * config/arm/neon-testgen.ml: Allow addresses to have an alignment.
