Types

type Encoding 

type Encoding struct {
	Name   []byte
	HasArg bool
	Input  inputMode
	Output outputMode
}

func EncodingOf 

func EncodingOf(kind InstrKind) *Encoding

type Instr 

type Instr struct {
	Kind InstrKind // Determines the instruction kind
	Data int32     // Instruction direct argument (optional)
	Meta string    // Additional instruction data (optional)
	Prev *Instr    // Previous instruction
	Next *Instr    // Next instruction
}

Instr is a single IR instruction.

func (*Instr) InsertLeft 

func (ins *Instr) InsertLeft(span []*Instr)

InsertLeft calls InsertPrev consequentially for each passed instruction. E.g.: [prev ins next].InsertLeft([a b]) => [prev a b ins next].

func (*Instr) InsertNext 

func (ins *Instr) InsertNext(newNext *Instr)

InsertNext adds instruction after current position.

func (*Instr) InsertPrev 

func (ins *Instr) InsertPrev(newPrev *Instr)

InsertPrev adds instruction before current position.

func (*Instr) InsertRight 

func (ins *Instr) InsertRight(span []*Instr)

InsertRight calls InsertNext consequentially for each passed instruction. E.g.: [prev ins next].InsertRight([a b]) => [prev ins a b next].

func (*Instr) Remove 

func (ins *Instr) Remove()

Remove destroys instruction object by removing it from instruction list.
