[cfe-dev] clang_indexSourceFile and CXCursor_(ParmDecl|VarDecl|DeclRefExpr)

[Anders Bakken]

Seems to work great except that I it gives me the references twice.

I get this output from the attached test:

test.cpp:2:7: CXXClass TemplateClass
test.cpp:5:5: CXXConstructor TemplateClass<T>
test.cpp:5:21: Variable t
test.cpp:5:30: Variable b
test.cpp:5:34: ref of Variable t test.cpp:5:21
test.cpp:5:34: ref of Variable t test.cpp:5:21
test.cpp:5:41: ref of Variable b test.cpp:5:30
test.cpp:5:45: ref of Variable t test.cpp:5:21
test.cpp:5:50: ref of Variable b test.cpp:5:30
test.cpp:8:7: CXXClass NonTemplateClass
test.cpp:11:5: CXXConstructor NonTemplateClass
test.cpp:14:5: Function main
test.cpp:16:24: Variable tt
test.cpp:16:24: ref of CXXConstructor TemplateClass test.cpp:5:5
test.cpp:16:24: ref of CXXConstructor TemplateClass test.cpp:5:5
test.cpp:17:22: Variable t
test.cpp:17:22: ref of CXXConstructor NonTemplateClass test.cpp:11:5
test.cpp:17:5: ref of CXXClass NonTemplateClass test.cpp:8:7
test.cpp:17:22: ref of CXXConstructor NonTemplateClass test.cpp:11:5

E.g.

$ ./clangtest | sort | uniq -c
      1 test.cpp:11:5: CXXConstructor NonTemplateClass
      1 test.cpp:14:5: Function main
      1 test.cpp:16:24: Variable tt
      2 test.cpp:16:24: ref of CXXConstructor TemplateClass test.cpp:5:5
      1 test.cpp:17:22: Variable t
      2 test.cpp:17:22: ref of CXXConstructor NonTemplateClass test.cpp:11:5
      1 test.cpp:17:5: ref of CXXClass NonTemplateClass test.cpp:8:7
      1 test.cpp:2:7: CXXClass TemplateClass
      1 test.cpp:5:21: Variable t
      1 test.cpp:5:30: Variable b
      2 test.cpp:5:34: ref of Variable t test.cpp:5:21
      1 test.cpp:5:41: ref of Variable b test.cpp:5:30
      1 test.cpp:5:45: ref of Variable t test.cpp:5:21
      1 test.cpp:5:50: ref of Variable b test.cpp:5:30
      1 test.cpp:5:5: CXXConstructor TemplateClass<T>
      1 test.cpp:8:7: CXXClass NonTemplateClass

On a not necessarily related topic. I was kinda expecting a reference
to TemplateClass at 16:5:

E.g. something like this:

 test.cpp:16:5: ref of CXXClass NonTemplateClass test.cpp:2:7

Is this expected behavior? Thanks again.

Anders
