Subject: Check whether DependentScopeDeclRefExpr's NestedNameSpecifier exists before accessing... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=274f83c2ece9041a1994fc3eacfe812ca86095e8;p=clang

Check whether DependentScopeDeclRefExpr's NestedNameSpecifier exists before accessing it, both for consistency (see StmtPrinter::VisitDeclRefExpr()) and for other use cases of dependent types.
