Classes

AddressOperand	The address operand of an instruction that loads or stores a value from memory (e.g. `Load`, `Store`).
ArgumentOperand	An operand representing an argument to a function call. This includes both positional arguments (represented by `PositionalArgumentOperand`) and the implicit `this` argument, if any (represented by `ThisArgumentOperand`).
BufferSizeOperand	The buffer size operand of an instruction that represents a read or write of a buffer.
CallTargetOperand	The operand representing the target function of an `Call` instruction.
ChiPartialOperand	The partial operand of a Chi node, representing the value being written to part of the memory.
ChiTotalOperand	The total operand of a Chi node, representing the previous value of the memory.
ConditionOperand	The condition operand of a `ConditionalBranch` or `Switch` instruction.
LeftOperand	The left operand of a binary instruction (e.g. `Add`, `CompareEQ`).
LoadOperand	The source value operand of an instruction that loads a value from memory (e.g. `Load`, `ReturnValue`, `ThrowValue`).
MemoryOperand	An operand that consumes a memory result (e.g. the `LoadOperand` on a `Load` instruction).
NonPhiMemoryOperand	A memory operand other than the operand of a `Phi` instruction.
NonPhiOperand	An operand that is not an operand of a `PhiInstruction`.
Operand	An operand of an `Instruction`. The operand represents a use of the result of one instruction (the defining instruction) in another instruction (the use instruction)
PhiInputOperand	An operand of a `PhiInstruction`.
PositionalArgumentOperand	An operand representing an argument to a function call.
RegisterOperand	An operand that consumes a register (non-memory) result.
RightOperand	The right operand of a binary instruction (e.g. `Add`, `CompareEQ`).
SideEffectOperand	An operand representing memory read as a side effect of evaluating another instruction.
StoreValueOperand	The source value operand of a `Store` instruction.
ThisArgumentOperand	An operand representing the implicit `this` argument to a member function call.
TypedOperand	A memory operand whose type may be different from the type of the result of its definition.
UnaryOperand	The sole operand of a unary instruction (e.g. `Convert`, `Negate`, `Copy`).
