[LLVMdev] Correct use of StringRef and Twine
...e issue.
So here are my ideas:
1) the easy solution: create a StringRef subclass (or new type with a
similarly expressive API) that wraps a buffer that it may or may not
use. Give it a ctor that takes a Twine. The use case then goes from
this:
SmallVectorImpl<char> v;
StringRef s = theTwine.GetStringRef(v);
to this:
TwineString s(theTwine);
(& the ctor looks like: TwineString(const Twine& t) { *this =
t.GetStringRef(this->buffer); })
So any Twine sink now has to pay one line of code to get a usable
string out of a Twine. Cheap to implement, easy to fix existing use
c...
