Enum rustc_codegen_ssa::mir::operand::OperandValue

pub enum OperandValue<V> {
    Ref(V, Option<V>, Align),
    Immediate(V),
    Pair(V, V),
}

The representation of a Rust value. The enum variant is in fact uniquely determined by the value's type, but is kept as a safety check.

Variants

Ref(V, Option<V>, Align)

A reference to the actual operand. The data is guaranteed to be valid for the operand's lifetime. The second value, if any, is the extra data (vtable or length) which indicates that it refers to an unsized rvalue.

Immediate(V)

A single LLVM value.

Pair(V, V)

A pair of immediate LLVM values. Used by fat pointers too.
