[cfe-dev] [Patch] DeclContext printer

[Zhongxing Xu]

Hi,

Attached patch implements an initial framework of a DeclContextPrinter. It
can print DeclContext and its Decls in indented format. An Example:

$ cat 3.cpp
class A {
  int a;
  void f();
};
void A::f() {
  a = 3;
}

$ clang -print-decl-contexts 3.cpp
[translation unit] 0x9754d7c
    <typedef> __builtin_va_list
    [class] A 0x9753310
        <class> A 0x975ce20
        <field> a
        <c++ method> f
        <c++ ctor> A
        <c++ ctor> A
        <c++ method> operator=
        <c++ dtor> ~A
    [c++ method] f [[0x9753310]]

Some comments: '<>' indicates a declaration, '[]' indicates a definition,
'[[ ]]' displays the semantic DeclContext which is different from the
lexical DeclContext.

This visualization should be helpful for DeclContext debugging.
