Golang RaceRead Examples

Example #1

File: race.go Project: redcatmiss/gcc

func StoreUintptr(addr *uintptr, val uintptr) {
	runtime.RaceSemacquire(&mtx)
	runtime.RaceRead(unsafe.Pointer(addr))
	*addr = val
	runtime.RaceRelease(unsafe.Pointer(addr))
	runtime.RaceSemrelease(&mtx)
}

Example #2

File: race.go Project: redcatmiss/gcc

func LoadUintptr(addr *uintptr) (val uintptr) {
	runtime.RaceSemacquire(&mtx)
	runtime.RaceRead(unsafe.Pointer(addr))
	runtime.RaceAcquire(unsafe.Pointer(addr))
	val = *addr
	runtime.RaceSemrelease(&mtx)
	return
}

Example #3

File: race.go Project: h8liu/golang

func StorePointer(addr *unsafe.Pointer, val unsafe.Pointer) {
	_ = *addr
	runtime.RaceSemacquire(&mtx)
	runtime.RaceRead(unsafe.Pointer(addr))
	*addr = val
	runtime.RaceRelease(unsafe.Pointer(addr))
	runtime.RaceSemrelease(&mtx)
}

Example #4

File: race.go Project: redcatmiss/gcc

func AddUint32(val *uint32, delta uint32) (new uint32) {
	runtime.RaceSemacquire(&mtx)
	runtime.RaceRead(unsafe.Pointer(val))
	runtime.RaceAcquire(unsafe.Pointer(val))
	*val = *val + delta
	new = *val
	runtime.RaceReleaseMerge(unsafe.Pointer(val))
	runtime.RaceSemrelease(&mtx)

	return
}

Example #5
