Enum rustc_target::abi::call::PassMode

pub enum PassMode {
    Ignore,
    Direct(ArgAttributes),
    Pair(ArgAttributes, ArgAttributes),
    Cast(CastTarget),
    Indirect(ArgAttributes, Option<ArgAttributes>),
}

Variants

Ignore

Ignore the argument (useful for empty struct).

Direct(ArgAttributes)

Pass the argument directly.

Pair(ArgAttributes, ArgAttributes)

Pass a pair's elements directly in two arguments.

Cast(CastTarget)

Pass the argument after casting it, to either a single uniform or a pair of registers.

Indirect(ArgAttributes, Option<ArgAttributes>)

Pass the argument indirectly via a hidden pointer. The second value, if any, is for the extra data (vtable or length) which indicates that it refers to an unsized rvalue.
