func AnyOverlap ¶

func AnyOverlap(x, y []byte) bool

AnyOverlap reports whether x and y share memory at any (not necessarily corresponding) index. The memory beyond the slice length is ignored.

func Clear ¶

func Clear(p unsafe.Pointer, sz uintptr)

func Equal ¶

func Equal(p, q unsafe.Pointer, sz uintptr) bool

func InexactOverlap ¶

func InexactOverlap(x, y []byte) bool

InexactOverlap reports whether x and y share memory at any non-corresponding index. The memory beyond the slice length is ignored. Note that x and y can have different lengths and still not have any inexact overlap.

InexactOverlap can be used to implement the requirements of the crypto/cipher AEAD, Block, BlockMode and Stream interfaces.

func Move ¶

func Move(dst, src unsafe.Pointer, sz uintptr)

func ReadUnaligned32 ¶

func ReadUnaligned32(p unsafe.Pointer) uint32

func ReadUnaligned64 ¶

func ReadUnaligned64(p unsafe.Pointer) uint64

func TypedMove ¶

func TypedMove(typ *abi.Type, dst, src unsafe.Pointer)

TypedMove copies a value of type typ to dst from src. Must be nosplit, see #16026.

TODO: Perfect for go:nosplitrec since we can't have a safe point anywhere in the bulk barrier or Move.
