I am using clang 3.8.1 libtooling library. I have written visitor for c++ auto types. When I try to get the deduced type I get NULL-TYPE.

Did anybody face a similar issue? Please enlighten me on auto type deduction in clang as it is leading me nowhere.

sample code:

bool ASTPrinter::VisitAutoTypeLoc(AutoTypeLoc TL) { 

std::string deducedTypeSig = TL.getType().getAsString(); 

if (TL.getTypePtr()->isDeduced()) { 
  deducedTypeSig = TL.getTypePtr()->getDeducedType().getAsString(); 
 } 
}

Any code to share? – Angew is no longer proud of SO Feb 14 '17 at 06:44
`bool ASTPrinter::VisitAutoTypeLoc(AutoTypeLoc TL) { std::string deducedTypeSig = TL.getType().getAsString(); if (TL.getTypePtr()->isDeduced()) { deducedTypeSig = TL.getTypePtr()->getDeducedType().getAsString(); } }` – Hemant Feb 14 '17 at 06:51
In the above snippet, isDeduced() always return false. – Hemant Feb 14 '17 at 06:55
Can you please [edit] the code and explanation into the question instead of posting a hard-to-read one-liner in comments? Ideally provide a [mcve]. – Angew is no longer proud of SO Feb 14 '17 at 07:20
