[Bug tree-optimization/33993] [4.3 Regression] ICE: verify_stmts failed (invalid reference prefix)



------- Comment #4 from jakub at gcc dot gnu dot org  2007-11-05 10:10 -------
There are two issues IMHO, one is that in this case the vectorizer should
create VECTOR_CST rather than CONSTRUCTOR, because it is really known to be
constant.  That cures this ICE, though you are right that CONSTRUCTORs inside
of
VIEW_CONVERT_EXPR shouldn't be diagnosed as invalid, both CONSTRUCTORs with
empty initializer and all VECTOR_TYPE CONSTRUCTORs are left in GIMPLE by the
gimplifier.
