		Optional< unsigned >	Flags = `None`
	)

inline

Build and insert Res = G_ADD Op0, Op1.

G_ADD sets Res to the sum of integer parameters Op0 and Op1, truncated to their width.

Precondition: setBasicBlock or setMI must have been called.; Res, Op0 and Op1 must be generic virtual registers with the same (scalar or vector) type).

Returns: a MachineInstrBuilder for the newly created instruction.

inline

Build and insert Res = G_AND Op0, Op1.

G_AND sets Res to the bitwise and of integer parameters Op0 and Op1.

Precondition: setBasicBlock or setMI must have been called.; Res, Op0 and Op1 must be generic virtual registers with the same (scalar or vector) type).

Returns: a MachineInstrBuilder for the newly created instruction.

◆ buildAnyExt()

MachineInstrBuilder MachineIRBuilder::buildAnyExt	(	const DstOp &	Res,
		const SrcOp &	Op
	)

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

Returns: The newly created instruction.

MachineInstrBuilder MachineIRBuilder::buildAtomicCmpXchg	(	Register	OldValRes,

Build and insert Res, CarryOut = G_UADDE Op0, Op1, CarryIn.

G_UADDE sets Res to Op0 + Op1 + CarryIn (truncated to the bit width) and sets CarryOut to 1 if the result overflowed in unsigned arithmetic.

Precondition: setBasicBlock or setMI must have been called.; Res, Op0 and Op1 must be generic virtual registers with the same scalar type.; CarryOut and CarryIn must be generic virtual registers with the same scalar type (typically s1)

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

G_GEP adds Value bytes to the pointer specified by Op0, storing the resulting pointer in Res. If Value is zero then no G_GEP 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 materializeGEP() and buildGEP().
