Precondition: setBasicBlock or setMI must have been called.; Res must be a generic virtual register with scalar or vector type.; Op must be a generic virtual register with scalar or vector type.; Op must be smaller than Res

Returns: The newly created instruction.

std::optional< MachineInstrBuilder > MachineIRBuilder::materializePtrAdd	(	Register &	Res,

	)

Materialize and insert Res = G_PTR_ADD Op0, (G_CONSTANT Value)

G_PTR_ADD adds Value bytes to the pointer specified by Op0, storing the resulting pointer in Res. If Value is zero then no G_PTR_ADD or G_CONSTANT will be created and

Precondition: Op0 will be assigned to Res.; setBasicBlock or setMI must have been called.; Op0 must be a generic virtual register with pointer type.; ValueTy must be a scalar type.; Res must be 0. This is to detect confusion between materializePtrAdd() and buildPtrAdd().

Postcondition: Res will either be a new generic virtual register of the same type as Op0 or Op0 itself.

Returns: a MachineInstrBuilder for the newly created instruction.
