Class NonPhiOperand

An operand that is not an operand of a PhiInstruction.

Fields

Predicates

getDumpId

Gets a string that uniquely identifies this operand on its use instruction.

getDumpLabel

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

getDumpSortOrder

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

getOperandTag

Gets the OperandTag that specifies how this operand is used by its Instruction.

getUse

Gets the Instruction that consumes this operand.

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
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
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.
