[cfe-dev] [StaticAnalyzer]: Cant get my checker to output

[funceval]

Hi,

How do I find out if my checker has run or not? There doesn't seem to be any
option in scan-build that tells us which checkers were run. I tried printing
to std::cout, std::cerr but nothing got printed. I tried generating a bug
report but that didn't get generated either. But my checker does show up in
the list of checkers when I run scan-build. I have even entered the details
in Checkers.td.

Here is what I have tried far:

namespace {
          class ConstantConditionChecker : public
Checker<check::PostStmt<IfStmt> >{
              mutable llvm::OwningPtr<BuiltinBug> BT;
          public:
                  void checkPostStmt(const IfStmt *ifStmt, CheckerContext
&C) const;
          };
  }

  void ConstantConditionChecker::checkPostStmt(const IfStmt *ifStmt,
CheckerContext &C) const
  {
      ASTContext& astContext = C.getASTContext();
      std::string sbuf;
      llvm::raw_string_ostream Out(sbuf);

      ifStmt->getCond()->printPretty(Out, NULL,
PrintingPolicy(astContext.getLangOptions()));
      std::cerr << Out.str() << std::endl;
      std::cout << "Hello\n" << std::endl;
      std::cerr << "Hello cerr" << std::endl;
      if (!BT)
          BT.reset(new BuiltinBug(Out.str().c_str()));
      BugReport* R = new BugReport(*BT, BT->getDescription(),
C.getPredecessor());
      R->addRange(ifStmt->getSourceRange());
      C.EmitReport(R);

  }

  void ento::registerConstantConditionChecker(CheckerManager &mgr) {
      mgr.registerChecker<ConstantConditionChecker>();
  }
