		const SrcOp &	Src0,
		const SrcOp &	Src1,
		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.

◆ buildAnyExt()

MachineInstrBuilder MachineIRBuilder::buildAnyExt	(	const DstOp &	Res,

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

		unsigned	Op0,
		uint32_t	NumBits

Build and insert Res = G_PTR_MASK Op0, NumBits.

G_PTR_MASK clears the low bits of a pointer operand without destroying its pointer properties. This has the effect of rounding the address down to a specified alignment in bits.

Build and insert instructions to put Ops together at the specified p Indices to form a larger register.

If the types of the input registers are uniform and cover the entirity of Res then a G_MERGE_VALUES will be produced. Otherwise an IMPLICIT_DEF followed by a sequence of G_INSERT instructions.

Precondition: setBasicBlock or setMI must have been called.; The final element of the sequence must not extend past the end of the destination register.; The bits defined by each Op (derived from index and scalar size) must not overlap.; Indices must be in ascending order of bit position.

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