--- Comment #3 from Richard Biener  ---
I don't think compiling with -mavx is desired here.  The "bug" is that
DECL_MODE doesn't have the same special-casing of vectors as TYPE_MODE has
and ...

/* Holds the machine mode corresponding to the declaration of a variable or
   field.  Always equal to TYPE_MODE (TREE_TYPE (decl)) except for a
   FIELD_DECL.  */
#define DECL_MODE(NODE) (DECL_COMMON_CHECK (NODE)->decl_common.mode)

... the comment also is wrong here.

Not sure if we really want to change the above to sth like

#define DECL_MODE(NODE) \
 (VECTOR_TYPE_P (TREE_TYPE (NODE)) \
  ? vector_type_mode (TREE_TYPE (NODE)) \
  : DECL_COMMON_CHECK (NODE)->decl_common.mode)

though.  Maybe changing references to DECL_MODE to use TYPE_MODE in some
selected places would be enough ...
