--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The costs look weird: _1 1 times scalar_store costs 12 in body _5 1 times scalar_store costs 12 in body _1 1 times vector_store costs 12 in body <unknown> 1 times vec_construct costs 8 in prologue vec_construct is certainly more expensive than a store (especially in this case when it is a store into a TImode variable which isn't addressable and will not be in memory at all).
