--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'll take a look.  We have

t.c:5:6: note: node 0x4c87020 (max_nunits=2, refcnt=1) vector(2) long unsigned
int
t.c:5:6: note: op template: c.4_4 = (long unsigned int) c_lsm.17_11;
t.c:5:6: note:  stmt 0 c.4_4 = (long unsigned int) c_lsm.17_11;
t.c:5:6: note:  children 0x4c870b0

but

_5 = c.4_4 + h_17;
