vec_ version built-ins are defined in rs6000-overload.def. Yes, they're fine
and in line with the definition in PVIPR.

[VEC_VEEDP, vec_extract_exp_dp, __builtin_vec_extract_exp_dp]
  vull __builtin_vec_extract_exp_dp (vd);
    VEEDP  VEEDP_DEPR1

[VEC_VEESP, vec_extract_exp_sp, __builtin_vec_extract_exp_sp]
  vui __builtin_vec_extract_exp_sp (vf);
    VEESP  VEESP_DEPR1

[VEC_VEE, vec_extract_exp, __builtin_vec_extract_exp]
  vui __builtin_vec_extract_exp (vf);
    VEESP
  vull __builtin_vec_extract_exp (vd);
    VEEDP

vec-extract-exp-2.c:12:3: note: overloaded builtin ‘__builtin_vec_extract_exp’ 
is implemented by builtin ‘__builtin_vsx_extract_exp_dp’

Thanks
