CompilerSupported includes constraints here and also the assembler.

MmapCodeSegment copies the code into the executable region and returns the byte slice of the region.

MprotectRX is like syscall.Mprotect with RX permission.

MunmapCodeSegment unmaps the given memory region.

Nanosleep implements sys.Nanosleep with time.Sleep.

Nanotime implements sys.Nanotime with runtime.nanotime() if CGO is available and time.Since if not.

NewFakeNanotime implements sys.Nanotime that increases by 1ms each reading.

NewFakeRandSource returns a deterministic source of random values.

NewFakeWalltime implements sys.Walltime with FakeEpochNanos that increases by 1ms each reading.

ToPosixPath returns the input, as only windows might return backslashes.

Walltime implements sys.Walltime with time.Now.
