Struct miri::OpTy

source ·

pub struct OpTy<'tcx, Prov = AllocId>where
    Prov: Provenance,{
    op: Operand<Prov>,
    pub layout: TyAndLayout<'tcx, Ty<'tcx>>,
    pub align: Option<Align>,
}

Fields§

§op: Operand<Prov>§layout: TyAndLayout<'tcx, Ty<'tcx>>§align: Option<Align>

rustc does not have a proper way to represent the type of a field of a repr(packed) struct: it needs to have a different alignment than the field type would usually have. So we represent this here with a separate field that “overwrites” layout.align. This means layout.align should never be used for an OpTy! None means “alignment does not matter since this is a by-value operand” (Operand::Immediate); this field is only relevant for Operand::Indirect. Also CTFE ignores alignment anyway, so this is for Miri only.
