since

```
we can change
```
if (!Args.hasArg(options::OPT_mtocdata))
return false;
const Arg *LastArg =
Args.getLastArg(options::OPT_mtocdata, options::OPT_mno_tocdata);
return LastArg->getOption().matches(options::OPT_mtocdata);
```
to
```
if(const Arg *LastArg = Args.getLastArg(options::OPT_mtocdata,
options::OPT_mno_tocdata))
return LastArg->getOption().matches(options::OPT_mtocdata);
else
return false;
```
