[cfe-users] Unknown type name extraction from AST.

[Hemant Bhagat via cfe-users]

Hi,



How do I get the unknown type name while visiting AST nodes.



Example:

class Sample

{

  std::string strMember;

}




I the above code if the #include  is missing then the AST will have an 
"invalid" for field declaration. I want to extract the token std::string as 
unknown type name.

Would you please help me to extract such unknown type names while visiting AST 
nodes.



Any kind of help will be really very appreciated as it is blocking the progress.



Thanks,

Hemant

[cfe-users] Is there any base container for VarDeclExpr

[Hemant Bhagat via cfe-users]

Hi,

For the following declaration expression

int I, j, k = 10;
^^


Is there any base container in clang AST for the above complete expression.
I have generated the AST for the above expression and what I see is there is 
not common expression for all three variables.
Each variable I, j, k I get separate varDeclVisitor.

Is there any way to traverse the complete expression and then individual 
variable?

Thanks,
Hemant

[cfe-users] Stakoverflow exception while parsing clang test file p2-0x.cpp with clang frontend.

[Hemant Bhagat via cfe-users]

Hi,

I have written a custom RecursiveASTVisitor class according to the following 
link.
http://clang.llvm.org/docs/RAVFrontendAction.html

Now I am giving clang source code to my frontend tool for analysis.
The problem is for the test case
llvm-3.8.1.src\tools\cfe-3.8.1.src\test\CXX\expr\expr.const\p2-0x.cpp

>From the documentation of this test case, It is for undefined behaviour.
But clang can generate its AST.
And while running ClangTool on this test it throws stackoverflow exception even 
before the control comes in HandleTranslationUnit.

I am really very confused about the control flow and why this exception is 
coming.
Is this the expected behaviour. Then how to traverse the generated AST and 
visit the nodes.

Thanks,
Hemant Bhagat
