[cfe-dev] how to properly initialize builtins for RecursiveASTVisitor

[Peeter Joot]

I've added the AddPath()'s for my system headers, but now get errors like:

.../bin/../lib/clang/3.3/include/stdarg.h:30:9: error: unknown type name
'__builtin_va_list'; did you mean '__builti
.../osse/core/inc/ossmath.h:48:11: error: use of undeclared identifier
'__builtin_sqrt'; did you mean '__builtin_


I'm guessing this is due to how I'm initializing the builtin context:

      Builtin::Context builtinContext ;

      builtinContext.InitializeTarget( *pTargetInfo ) ;

      ASTContext * pASTcontext = new ASTContext( languageOptions,
                                                 sourceManager,
                                                 pTargetInfo,
                                                 identifierTable,
                                                 selectorTable,
                                                 builtinContext,
                                                 0 /* size_reserve*/ ) ;

I tried adding:

      builtinContext.InitializeBuiltins( identifierTable, languageOptions )
;

before the ASTContext creation, but this doesn't appear to have an effect?
 My Langopts now include:

   languageOptions.GNUMode          = 1 ;
   languageOptions.CXXExceptions    = 1 ;
   languageOptions.RTTI             = 1 ;
   languageOptions.Bool             = 1 ;
   languageOptions.CPlusPlus        = 1 ;
   languageOptions.WChar            = 1 ;

and I see that NoBuiltin is already 0 by default?
