--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
/* Build a vector type with the alignment of the target
location in order to enable correct alignment hints to be
generated for vst. */
tree mem_type = build_aligned_type (TREE_TYPE((*arglist)[0]),
TYPE_ALIGN (TREE_TYPE (TREE_TYPE
((*arglist)[2]))));
return build2 (MODIFY_EXPR, mem_type,
build1 (INDIRECT_REF, mem_type,
fold_build_pointer_plus ((*arglist)[2],
(*arglist)[1])),
(*arglist)[0]);
Does -fno-strict-aliasing help? I wonder if the above (which is
S390_OVERLOADED_BUILTIN_s390_vec_xst from s390_expand_overloaded_builtin)
should be have an may_alias variant .
