--- Comment #9 from Kewen Lin <linkw at gcc dot gnu.org> ---
inline_call will force reload global optimization.

  /* Reload global optimization flags.  */
  if (reload_optimization_node && DECL_STRUCT_FUNCTION (to->decl) =3D=3D cf=
un)
    set_cfun (cfun, true);

It looks that ix86_set_current_function can create one new target option no=
de
even if fndecl =3D=3D ix86_previous_fndecl but flag_unsafe_math_optimizatio=
ns (or
flag_excess_precision) !=3D the corresponding values in the associated targ=
