Suboptimal string copying in ns
Attr Value::To String
(In reply to Boris Zbarsky from bug 760331 comment #8) > (From update of attachment 665541 [details] [diff] [review]) > > +MiscContainer::Cache() > > + nsString str; > You could probaly just use an nsDependentString Unfortunately nsAttrValue::ToString ends up copying the dependent string to its outparam, whereas with nsAString& it could simply forward the retval.
