Target| |x86_64-*-*
--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
No, it's indeed plain -O2 with the default architecture level, thus SSE2 only.
For the case of "complex" expansions we might want to bite the bullet and
fix the GIGO vectorizer cost modeling in the target. add_stmt_cost should
use ix86_multiplication_cost here passing down V2SImode. There's cases
for various integer multiplication emulations but your patch didn't amend
this function for the new V2SImode emulation w/o SSE4.
