示例1: NumParams

const AttributeList &Attr, Sema &S) {
// Check the attribute arguments.
if (Attr.getNumArgs() != 1) {
S.Diag(Attr.getLoc(), diag::err_attribute_wrong_number_arguments) << 1;
return;
}
// FIXME: Check for decl - it should be void ()(void).
Expr *NumParamsExpr = static_cast<Expr *>(Attr.getArg(0));
llvm::APSInt NumParams(32);
if (!NumParamsExpr->isIntegerConstantExpr(NumParams, S.Context)) {
