Types

type BC

type BC struct {
	N    int // size
	Code []*instruction.Inst
}

BC represents a line of instructions.

func NewByteCode

func NewByteCode() *BC

NewByteCode returns a new BC.

func (*BC) AddCode

func (bc *BC) AddCode(bc2 BC, i int)

AddCode inserts the argument bytecode into BC. The argument integer i is the index where will insert into.

func (*BC) AddInst

func (bc *BC) AddInst(inst *instruction.Inst, i int)

AddInst adds the argument instruction to BC. The argument integer i is the index where will insert to.

func (BC) IndexOf

func (bc BC) IndexOf(sinst *instruction.Inst) int

IndexOf returns the position of argument instruction in BC. If can't find, then return -1.

func (*BC) Optimize

func (bc *BC) Optimize()

Optimize optimizes (or minimize) the bytecode.

func (*BC) PushCode

func (bc *BC) PushCode(bc2 BC)

PushCode inserts the argument bytecode into the top of BC.

func (*BC) PushInst

func (bc *BC) PushInst(inst *instruction.Inst)

PushInst adds the argument instruction to the top of BC.

func (BC) String

func (bc BC) String() string
