Build and insert Res = G_ANYEXT Op0.

G_ANYEXT produces a register of the specified width, with bits 0 to sizeof(Ty) * 8 set to Op. The remaining bits are unspecified (i.e. this is neither zero nor sign-extension). For a vector register, each element is extended individually.

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

MachineInstrBuilder MachineIRBuilder::buildIntrinsic	(	Intrinsic::ID	ID,

		bool	HasSideEffects,
		bool	isConvergent
	)

Build and insert a G_INTRINSIC instruction.

There are four different opcodes based on combinations of whether the intrinsic has side effects and whether it is convergent. These properties can be specified as explicit parameters, or else they are retrieved from the MCID for the intrinsic.

The parameter Res provides the Registers or MOs that will be defined by this instruction.

Precondition: setBasicBlock or setMI must have been called.

Returns: a MachineInstrBuilder for the newly created instruction.

◆ materializePtrAdd()

std::optional< MachineInstrBuilder > MachineIRBuilder::materializePtrAdd	(	Register &	Res,
		Register	Op0,
		const LLT	ValueTy,
		uint64_t	Value
	)

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.
