--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
But that constraint is not the issue here anyways.


Also this has been fixed on the trunk by late_combine:

trying to combine definition of r12 in:
   80: ip:SI=0xf0
      REG_EQUIV 0xf0
into:
  155: r5:SI=ip:SI
successfully matched this instruction to *thumb2_movsi_vfp:
(set (reg:SI 5 r5 [164])
    (const_int 240 [0xf0]))
