--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> --- Ok, so I have a patch that works until we get to try constant folding a vector load from an array of elements. There both native_encode_expr and fold_ctor_reference fail (the first because it doesn't handle CONSTRUCTORs yet the latter because it doesn't handle multi-field/index results). The idea was to get CONSTRUCTOR support into native_encode_expr which would then handle the fully-constant cases (but not initializers with constant addresses like &global-var). Of course it wouldn't help as FRE isn't run late. Hah.
