I should add that this exposed two assembly comparison failures which slipped in a previous check-in when this problem was still up. Namely: FAIL: g++.dg/pph/x1dynarray0.cc (assembly comparison) FAIL: g++.dg/pph/x1dynarray1.cc (assembly comparison)
Lawrence is reorganizing those tests as we speak and told me not to bother marking them as `pph asm xdiff` as part of this check-in. http://codereview.appspot.com/4635087/
