[cfe-dev] CLANG Function Def... How to get Entire SourceRange

[Manuel Klimek]

$ cat t.cc
extern "C" void f();

$ clang++ -cc1 -ast-dump-xml t.cc
[...]
 <LinkageSpec ptr="0x38577f0" lang="C">
  <Function ptr="0x38872f0" name="f" prototype="true" storage="extern">
   <FunctionProtoType ptr="0x3857840" canonical="0x3857840">
    <BuiltinType ptr="0x3856c30" canonical="0x3856c30"/>
    <parameters/>
   </FunctionProtoType>
  </Function>
 </LinkageSpec>

searching for LinkageSpec in the code base leads to LinkageSpecDecl,
which is a DeclContext, so without having verified it I'd expect
FD->getDeclContext() to give the LinkageSpecDecl in that case (but I'm
not sure).

Cheers,
