[cfe-dev] unable to traverse FunctionTemplateDecl (right name?) with either RecursiveASTVisitor or Matcher

[John P. Feltz]

No change:

visiting func decl: f
visiting func decl: g
visiting func decl: main

Also with:
ci->getDiagnostics().setSuppressAllDiagnostics(false);

file.cc:1:10: fatal error: 'iostream' file not found
#include <iostream>
visiting func decl: f
visiting func decl: g
visiting func decl: main

also h() shows up for #include <iostream_adsf> in both:
$ clang-query file.cc --
clang-query> m functionTemplateDecl()

and,
$ clang -Xclang -ast-dump -fsyntax-only file.cc
