--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  omp expansion seems to introudce this non-gimple code and likely
also makes 'i' not a register (for OACC):

  .data_dep.5D.4044 = .UNIQUE (OACC_PRIVATE, .data_dep.5D.4044, -1, &iD.4045);

but

  iD.4045 = 1 + .offset.9D.4049;

and

  iD.4045 = 1 + 8;

(which is also unfolded)
