Functions ¶

func Generate ¶

func Generate(w io.Writer, F *field.FieldConfig) error

Generate generates assembly code for the base field provided to goff see internal/templates/ops*

func GenerateMul ¶

func GenerateMul(w io.Writer, F *field.FieldConfig) error

func GenerateMulADX ¶

func GenerateMulADX(w io.Writer, F *field.FieldConfig) error

Types ¶

type FFAmd64 ¶

type FFAmd64 struct {
	*field.FieldConfig
	*amd64.Amd64
	// contains filtered or unexported fields
}

func NewFFAmd64 ¶

func NewFFAmd64(w io.Writer, F *field.FieldConfig) *FFAmd64

func (*FFAmd64) Add ¶

func (f *FFAmd64) Add(i1, i2 interface{}, offsets ...int)

func (*FFAmd64) AssertCleanStack ¶

func (f *FFAmd64) AssertCleanStack(reservedStackSize, minStackSize int)

func (*FFAmd64) GenerateDefines ¶

func (f *FFAmd64) GenerateDefines()

func (*FFAmd64) LabelRegisters ¶

func (f *FFAmd64) LabelRegisters(name string, r ...amd64.Register)

LabelRegisters write comment with friendler name to registers

func (*FFAmd64) Mov ¶

func (f *FFAmd64) Mov(i1, i2 interface{}, offsets ...int)

func (*FFAmd64) MulADX ¶

func (f *FFAmd64) MulADX(registers *amd64.Registers, x, y func(int) string, t []amd64.Register) []amd64.Register

MulADX uses AX, DX and BP sets x * y into t, without modular reduction x() will have more accesses than y() (caller should store x in registers, if possible) if no (tmp) register is available, this uses one PUSH/POP on the stack in the hot loop.

func (*FFAmd64) Pop ¶

func (f *FFAmd64) Pop(registers *amd64.Registers, forceStack ...bool) amd64.Register

func (*FFAmd64) PopN ¶

func (f *FFAmd64) PopN(registers *amd64.Registers, forceStack ...bool) []amd64.Register

func (*FFAmd64) Push ¶

func (f *FFAmd64) Push(registers *amd64.Registers, rIn ...amd64.Register)

func (*FFAmd64) Reduce ¶

func (f *FFAmd64) Reduce(registers *amd64.Registers, t []amd64.Register)

Reduce scratch can be on the stack or a set of registers.

func (*FFAmd64) ReduceElement ¶

func (f *FFAmd64) ReduceElement(t, scratch []amd64.Register)

func (*FFAmd64) StackSize ¶

func (f *FFAmd64) StackSize(maxNbRegistersNeeded, nbRegistersReserved, minStackSize int) int

func (*FFAmd64) Sub ¶

func (f *FFAmd64) Sub(i1, i2 interface{}, offsets ...int)
