Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target| |x86_64-*-* Status|UNCONFIRMED |NEW Last reconfirmed| |2016-11-18 Ever confirmed|0 |1 --- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- Confirmed. We're also expanding from pod copy_pod(pod) (struct pod d) { struct pod D.2314; ;; basic block 2, loop depth 0 ;; pred: ENTRY D.2314 = d; return D.2314; ;; succ: EXIT } which has one useless aggregate copy (somewhere we have a bug about not having aggregate copy propagation). The C++ FE emits <<cleanup_point return <retval> = TARGET_EXPR <D.2303, d>>>;
