--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The mvcle instructions actually aren't guarded by TARGET_MVCLE, they are
TARGET_64BIT || !TARGET_ZARCH
or
!TARGET_64BIT && TARGET_ZARCH
which means available everywhere, so TARGET_MVCLE seems just like an
optimization hint, defaulted for -Os, but which can be set separately.
So, I'd say we should use
  if ((caller_opts->x_target_flags
       & ~(MASK_SOFT_FLOAT | MASK_HARD_DFP | MASK_MVCLE))
      !=3D (callee_opts->x_target_flags
          & ~(MASK_SOFT_FLOAT | MASK_HARD_DFP | MASK_MVCLE)))
    ret =3D false;
or so.=
