If you like, you can bind the flag to a variable using the Var() functions.

	var flagvar int
	func init() {
		flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
	}

Or you can create custom flags that satisfy the Value interface (with
pointer receivers) and couple them to flag parsing by

	flag.Var(&flagVal, "name", "help message for flagname")

// Declare a user-defined flag type.
type flagVar []string

func (f *flagVar) String() string {
	return fmt.Sprint([]string(*f))
}

func (f *flagVar) Set(value string) error {
	*f = append(*f, value)
	return nil
}

func TestUserDefined(t *testing.T) {
	var flags FlagSet
	flags.Init("test", ContinueOnError)
	flags.SetOutput(io.Discard)
	var v flagVar
	flags.Var(&v, "v", "usage")

      static_cast<int>(is_weight_buffer);
  int64_t storage_max =
      QuantizedType::getDefaultMaximumForInteger(is_signed, bitwidth);
  uint32_t flags =
      is_signed ? mlir::quant::QuantizationFlags::FlagValue::Signed : 0;

  // Zero scales we make the minimum fp value, this is because some flatbuffers
  // contain zero scale for zero values.
  llvm::SmallVector<double> scales;
  for (float scale : quant_params.scale) {

	return nil
}

// validateCustomTags validates that tracing CustomTags map does not contain any nil items
func validateCustomTags(tags map[string]*meshconfig.Tracing_CustomTag) error {
	for tagName, tagVal := range tags {
		if tagVal == nil {
			return fmt.Errorf("encountered nil value for custom tag: %s", tagName)
		}
	}
	return nil
}

// ValidateFQDN checks a fully-qualified domain name

	flagExtar      = flag.String("extar", "", "archive program for buildmode=c-archive")

	flagCaptureHostObjs = flag.String("capturehostobjs", "", "capture host object files loaded during internal linking to specified dir")

	flagA             = flag.Bool("a", false, "no-op (deprecated)")
	FlagC             = flag.Bool("c", false, "dump call graph")
	FlagD             = flag.Bool("d", false, "disable dynamic executable")
