[Clang] Global closure types are never handled by ASTConsumer #157101
Description
Part of function body of void clang::ParseAST(Sema &S, bool PrintStats, bool SkipFunctionBodies):
for (bool AtEOF = P.ParseFirstTopLevelDecl(ADecl, ImportState); !AtEOF; AtEOF = P.ParseTopLevelDecl(ADecl, ImportState)) { // If we got a null return and something *was* parsed, ignore it. This // is due to a top-level semicolon, an action override, or a parse error // skipping something. if (ADecl && !Consumer->HandleTopLevelDecl(ADecl.get())) return; }If declarations introduce closure types in global scope, these types never appear in ADecl. As a result, Consumer never handles global closure types.
auto L = [] { // no Clang-Static-Analyzer-generated warning no matter what you write };
