示例1: convert
// convert converts the given value to the specified type, emitting code to f.
// No conversion is made, if v is already of the correct type.
func (m *Module) convert(f *Function, v value.Value, to irtypes.Type) value.Value {
// Early return if v is already of the correct type.
from := v.Type()
if irtypes.Equal(from, to) {
return v
}
fromType, ok := from.(*irtypes.Int)
if !ok {
panic(fmt.Sprintf("support for converting from type %T not yet implemented", from))
}
toType, ok := to.(*irtypes.Int)
if !ok {
panic(fmt.Sprintf("support for converting to type %T not yet implemented", to))
}
// Convert constant values.
if v, ok := v.(constant.Constant); ok {
switch v := v.(type) {

v, err := constant.NewInt(toType, v.ValueString())
if err != nil {
