Subject: Make StringSaver::save less ambiguous.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=53d587ee0390301d92ea289bdac557570f9a2973;p=llvm

Make StringSaver::save less ambiguous.

Previously, an expression such as Saver.save(std::string("foo") + "bar")
didn't compile because there is an ambiguity as to whether the argument
is of const Twine& or StringRef.
