void setExternalIdentifierLookup (IdentifierInfoLookup *IILookup)
Set the external identifier lookup mechanism.
IdentifierInfoLookup * getExternalIdentifierLookup () const
Retrieve the external identifier lookup object, if any.
llvm::BumpPtrAllocator & getAllocator ()
IdentifierInfo & get (StringRef Name)
Return the identifier token info for the specified named identifier.
IdentifierInfo & get (StringRef Name, tok::TokenKind TokenCode)
IdentifierInfo & getOwn (StringRef Name)
Gets an IdentifierInfo for the given name without consulting external sources.
iterator begin () const
iterator end () const
unsigned size () const
iterator find (StringRef Name) const
void PrintStats () const
Print some statistics to stderr that indicate how well the hashing is doing.
void AddKeywords (const LangOptions &LangOpts)
Populate the identifier table with info about the language keywords for the language specified by LangOpts.
diag::kind getFutureCompatDiagKind (const IdentifierInfo &II, const LangOptions &LangOpts)
Returns the correct diagnostic to issue for a future-compat diagnostic warning.

Implements an efficient mapping from strings to IdentifierInfo nodes.

This has no other purpose, but this is an extremely performance-critical piece of the code, as each occurrence of every identifier goes through here when lexed.
