Enum cranelift_codegen::ir::ArgumentExtension

pub enum ArgumentExtension {
    None,
    Uext,
    Sext,
}

Function argument extension options.

On some architectures, small integer function arguments are extended to the width of a general-purpose register.

Variants

None

No extension, high bits are indeterminate.

Uext

Unsigned extension: high bits in register are 0.

Sext

Signed extension: high bits in register replicate sign bit.
