Function Documentation

static void AddCXXOperatorKeyword ( StringRef  Keyword,
tok::TokenKind  TokenCode,
IdentifierTable Table 
)
static

AddCXXOperatorKeyword - Register a C++ operator keyword alternative representations.

static void AddKeyword ( StringRef  Keyword,
tok::TokenKind  TokenCode,
unsigned  Flags,
const LangOptions LangOpts,
IdentifierTable Table 
)
static

AddKeyword - This method is used to associate a token ID with specific identifiers because they are language keywords. This causes the lexer to automatically map matching identifiers to specialized token codes.
