pub struct CastTarget {
    pub prefix: [Option<Reg>; 8],
    pub rest: Uniform,
    pub attrs: ArgAttributes,
}
Expand description

Describes the type used for PassMode::Cast.

Passing arguments in this mode works as follows: the registers in the prefix (the ones that are Some) get laid out one after the other (using repr(C) layout rules). Then the rest.unit register type gets repeated often enough to cover rest.size. This describes the actual type used for the call; the Rust type of the argument is then transmuted to this ABI type (and all data in the padding between the registers is dropped).
