示例1: AddPragmaHandler

/// AddPragmaHandler - Add the specified pragma handler to the preprocessor.
/// If 'Namespace' is non-null, then it is a token required to exist on the
/// pragma line before the pragma string starts, e.g. "STDC" or "GCC".
void Preprocessor::AddPragmaHandler(const char *Namespace,
                                    PragmaHandler *Handler) {
  PragmaNamespace *InsertNS = PragmaHandlers;

  // If this is specified to be in a namespace, step down into it.
  if (Namespace) {
    IdentifierInfo *NSID = getIdentifierInfo(Namespace);

    // If there is already a pragma handler with the name of this namespace,
    // we either have an error (directive with the same name as a namespace) or
    // we already have the namespace to insert into.
    if (PragmaHandler *Existing = PragmaHandlers->FindHandler(NSID)) {
      InsertNS = Existing->getIfNamespace();
      assert(InsertNS != 0 && "Cannot have a pragma namespace and pragma"
             " handler with the same name!");
    } else {
      // Otherwise, this namespace doesn't exist yet, create and insert the
      // handler for it.
      InsertNS = new PragmaNamespace(NSID);
      PragmaHandlers->AddPragma(InsertNS);
    }
  }

  // Check to make sure we don't already have a pragma for this identifier.
  assert(!InsertNS->FindHandler(Handler->getName()) &&
         "Pragma handler already exists for this identifier!");
  InsertNS->AddPragma(Handler);
}
