Fields

Predicates

getField	Gets the field associated with this instruction.
getObjectAddress	Gets the instruction whose result provides the address of the object containing the field.
getObjectAddressOperand	Gets the operand that provides the address of the object containing the field.

Inherited predicates

getAnyDef	Gets the `Instruction` whose result is the value of the operand. Unlike `getDef`, this also has a result when `isDefinitionInexact` holds, which means that the resulting instruction may only partially or potentially be the value of this operand.	from Operand
getDef	Gets the `Instruction` whose result is the value of the operand. Unlike `getAnyDef`, this also has no result when `isDefinitionInexact` holds, which means that the resulting instruction must always be exactly the be the value of this operand.	from Operand
getDefinitionOverlap	Gets the overlap relationship between the operand’s definition and its use.	from Operand
getDumpId	Gets a string that uniquely identifies this operand on its use instruction.	from Operand
getDumpLabel	Gets a prefix to use when dumping the operand in an operand list.	from Operand
getDumpSortOrder	Get the order in which the operand should be sorted in the operand list.	from Operand
getDumpString	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.	from Operand
getEnclosingIRFunction	Gets the function that contains this operand.	from Operand
getIRType	Gets the language-neutral 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.	from Operand
getLanguageType	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.	from Operand
getLocation	Gets the location of the source code for this operand. By default this is where the operand is used, but some subclasses may override this using `getAnyDef()` if it makes more sense.	from Operand
getSize	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.	from Operand
getType	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.	from Operand
getUse	Gets the `Instruction` that consumes this operand.	from Operand
isDefinitionInexact	Holds if the result of the definition instruction does not exactly overlap this use.	from Operand
isGLValue	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 `getType()`.	from Operand
toString	Gets a textual representation of this element.	from Operand
