Functions

func GetMemoryCopyPadded

func GetMemoryCopyPadded(m []byte, offset, size int64) ([]byte, error)

GetMemoryCopyPadded returns offset + size as a new slice. It zero-pads the slice if it extends beyond memory bounds.

func MemoryPtr

func MemoryPtr(m []byte, offset, size int64) []byte

MemoryPtr returns a pointer to a slice of memory.

func StackBack

func StackBack(st []uint256.Int, n int) *uint256.Int

StackBack returns the n'th item in stack
