Enum rustc_target::abi::call::ArgExtension
source · pub enum ArgExtension {
None,
Zext,
Sext,
}
Expand description
Sometimes an ABI requires small integers to be extended to a full or partial register. This enum defines if this extension should be zero-extension or sign-extension when necessary. When it is not necessary to extend the argument, this enum is ignored.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
