var StopProfiling = os.Getenv("SONIC_STOP_PROFILING") != ""

StopProfiling is used to stop traceback introduced by SIGPROF while native code is running. WARN: this option is only a workaround for traceback issue (https://github.com/bytedance/sonic/issues/310), and will be dropped when the issue is fixed.

Functions

func BytesFrom added in v1.0.2 

func BytesFrom(p unsafe.Pointer, n int, c int) (r []byte)

func FuncAddr added in v1.0.2 

func FuncAddr(f interface{}) unsafe.Pointer

func GcwbAddr added in v1.0.2 

func GcwbAddr() uintptr

func Get16 

func Get16(v []byte) int16

func Get32 

func Get32(v []byte) int32

func Get64 

func Get64(v []byte) int64

func GuardSlice added in v1.6.1 

func GuardSlice(buf *[]byte, n int)

func IndexByte added in v1.6.1 

func IndexByte(ptr []byte, index int) unsafe.Pointer

func IndexChar added in v1.6.1 

func IndexChar(src string, index int) unsafe.Pointer

func Mem2Str 

func Mem2Str(v []byte) (s string)

func MoreStack 

func MoreStack(size uintptr)

func NoEscape added in v1.10.0 

func NoEscape(p unsafe.Pointer) unsafe.Pointer

NoEscape hides a pointer from escape analysis. NoEscape is the identity function but escape analysis doesn't think the output depends on the input. NoEscape is inlined and currently compiles down to zero instructions. USE CAREFULLY!
