Functions

func AllZero

func AllZero(b []byte) bool

Types

type Bitvec

type Bitvec []byte

Bitvec is a bit vector which maps bytes in a program. An unset bit means the byte is an opcode, a set bit means it's data (i.e. argument of PUSHxx).

func (*Bitvec) CodeSegment

func (bits *Bitvec) CodeSegment(pos uint64) bool

codeSegment checks if the position is in a code segment.

func (*Bitvec) Set

func (bits *Bitvec) Set(pos uint64)

func (*Bitvec) Set8

func (bits *Bitvec) Set8(pos uint64)
