Subject: The TokenLexer may encounter annotations if the parser enters them using Preprocessor... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6f421f91849418883186592051fce05339ee62e9;p=clang

The TokenLexer may encounter annotations if the parser enters them using Preprocessor::EnterTokenStream.
So check for annotation before using the Token's IdentifierInfo.
