ruiu added inline comments.
================
Comment at: clang/lib/Driver/Driver.cpp:1302
- llvm::outs() << llvm::join(SuggestedCompletions, " ") << '\n';
+ llvm::outs() << llvm::join(SuggestedCompletions, "\n") << '\n';
return false;
----------------
Now that the separator and the terminator are the same, there's no reason to
use llvm::join. Since llvm::join creates a large temporary string, you want to
avoid that if it is easily avoidable.
for (StringRef S : SuggestedCompletions)
llvm::outs << S << "\n";
If you do this, you might be able to remove StringExtras.h from this file?
================
Comment at: llvm/lib/Option/OptTable.cpp:240
if (StringRef(S).startswith(Cur))
- Ret.push_back(S);
+ Ret.push_back(S + "\t" + std::string(StringRef(In.HelpText)));
}
----------------
I believe
Ret.push_back(S + "\t" + In.HelpText);
should just work.
