示例1: RemovePragmaHandler
/// RemovePragmaHandler - Remove the specific pragma handler from the
/// preprocessor. If \arg Namespace is non-null, then it should be the
/// namespace that \arg Handler was added to. It is an error to remove
/// a handler that has not been registered.
void Preprocessor::RemovePragmaHandler(const char *Namespace,
PragmaHandler *Handler) {
PragmaNamespace *NS = PragmaHandlers;
// If this is specified to be in a namespace, step down into it.
if (Namespace) {
IdentifierInfo *NSID = getIdentifierInfo(Namespace);
PragmaHandler *Existing = PragmaHandlers->FindHandler(NSID);
assert(Existing && "Namespace containing handler does not exist!");
NS = Existing->getIfNamespace();
assert(NS && "Invalid namespace, registered as a regular pragma handler!");
}
NS->RemovePragmaHandler(Handler);
// If this is a non-default namespace and it is now empty, remove
// it.
if (NS != PragmaHandlers && NS->IsEmpty())
PragmaHandlers->RemovePragmaHandler(NS);
