It's graphite's rewrite_commutative_reductions_out_of_ssa that removes SSA PHI nodes from the IR without actually releasing them, so we don't get a chance to propagate the DEFs into debug stmts. I tried to explicitly call the debug stmt propagate function, before and after release, to no avail. I went no further than that, for the time being, and I'm not sure when/if I'll get back to it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42530
