The cgo tool will generate padding fields as needed to ensure that the fields are aligned as expected. It's true that the cgo tool does assume that it knows the alignment requirements of the basic types. These requirements are not normally changed by compiler options. The alignment requirements of unusual types, such as processor-specific vector types, are not relevant, since Go can't represent them and they will therefore never appear in the Go/C interface. Do you have a specific concern, or is this purely abstract? Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
