----------------
line 4624 to line 4635 can be simplified to :

```
  if (Triple.isOSAIX() && Args.hasArg(options::OPT_maltivec) {
    if (Args.hasArg(options::OPT_mabi_EQ_vec_extabi)) {
      CmdArgs.push_back("-mabi=vec-extabi");
    } else {
      D.Diag(diag::err_aix_default_altivec_abi);
    }
  }
```

or even simplify line 4617 -4636 to the following if it works:

```
  if (Arg *A = Args.getLastArg(options::OPT_mabi_EQ_vec_extabi,
                               options::OPT_mabi_EQ_vec_default)) {
    if (!Triple.isOSAIX())
      D.Diag(diag::err_drv_unsupported_opt_for_target)
          << A->getSpelling() << RawTriple.str();

    if (!Args.hasArg(options::OPT_maltivec))
      D.Diag(diag::err_aix_altivec);

    if (Args.hasArg(options::OPT_mabi_EQ_vec_default))
      D.Diag(diag::err_aix_default_altivec_abi);

    CmdArgs.push_back("-mabi=vec-extabi");
  } else if (Triple.isOSAIX() && Args.hasArg(options::OPT_maltivec) {
      D.Diag(diag::err_aix_default_altivec_abi);
  }
```

Hi Zarko, is the above comment missed being addressed?
