Class Operand::Operand

A source operand of an Instruction. The operand represents a value consumed by the instruction.

Direct supertypes

Known direct subtypes



Gets the Instruction whose result is the value of the operand.


Gets a prefix to use when dumping the operand in an operand list.


Get the order in which the operand should be sorted in the operand list.


Gets a string describing this operand, suitable for display in IR dumps. This consists of the result ID of the instruction consumed by the operand, plus a label identifying the operand kind.


Gets the size of the value consumed by this operand, in bytes. If the operand does not have a known constant size, this predicate does not hold.


Gets the type of the value consumed by this operand. This is usually the same as the result type of the definition instruction consumed by this operand. For register operands, this is always the case. For some memory operands, the operand type may be different from the definition type, such as in the case of a partial read or a read from a pointer that has been cast to a different type.


Gets the Instruction that consumes this operand.


Holds if the value consumed by this operand is a glvalue. If this holds, the value of the operand represents the address of a location, and the type of the location is given by getType(). If this does not hold, the value of the operand represents a value whose type is given by getResultType().
