Class ChiPartialOperand

Gets the kind of memory access performed by the operand.

Returns the operand that holds the memory address from which the current operand loads its value, if any. For example, in r3 = Load r1, m2, the result of getAddressOperand() for m2 is r1.

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.

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.

Gets the overlap relationship between the operand’s definition and its use.

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

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 function that contains this operand.

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.

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 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.

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

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 operand totally overlaps with its definition and consumes the bit range [startBitOffset, endBitOffset) relative to the start address of the definition.

Holds if the memory access performed by this operand will not always read from every bit in the memory location. This is most commonly used for memory accesses that may or may not actually occur depending on runtime state (for example, the write side effect of an output parameter that is not written to on all paths), or for accesses where the memory location is a conservative estimate of the memory that might actually be accessed at runtime (for example, the global side effects of a function call).

Holds if the result of the definition instruction does not exactly overlap this use.

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().

Gets a textual representation of this element.
