Functions | |
| static IdentifierInfo * | RegisterBuiltinMacro (Preprocessor &PP, const char *Name) |

| static bool | isTrivialSingleTokenExpansion (const MacroInfo *MI, const IdentifierInfo *MacroIdent, Preprocessor &PP) |
| isTrivialSingleTokenExpansion - Return true if MI, which has a single token in its expansion, currently expands to that token literally. More... | |

GenerateNewArgTokens - Returns true if OldTokens can be converted to a new vector of tokens in NewTokens.
The new number of arguments will be placed in NumArgs and the ranges which need to surrounded in parentheses will be in ParenHints. Returns false if the token stream cannot be changed. If this is because of an initializer list starting a macro argument, the range of those initializer lists will be place in InitLists.
