What version of Go are you using (go version)?

$ go version
go version go1.10.8 windows/amd64

Does this issue reproduce with the latest release?

Yes, since 1.13.0

What operating system and processor architecture are you using (go env)?

go env Output
$ go env
set GOARCH=amd64
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows

What did you do?

What did you expect to see?

No errors and warnings. Backward compatibility exists

What did you see instead?

../../../go/src/golang.org/x/sys/windows/syscall_windows.go:1791:11: invalid operation: 1 << pos (shift count type int, must be unsigned integer)
../../../go/src/golang.org/x/sys/windows/syscall_windows.go:1795:23: invalid operation: masked >> start (shift count type int, must be unsigned integer)

Sorry, Go 1.10 is no longer supported. You'll need to use at least Go 1.13. And you may need to set go 1.13 or later in your go.mod file.

ianlancetaylor But what happened with golang.org/x/sys?

Backwards compatibility means old code will run with newer language versions. Here you're trying to run new code with older language versions. This isn't covered by any compatibility promises.

@stranger-inthenight To put it another way, what happened is that somebody committed a change to x/sys/windows that uses a language feature that was added in Go 1.13. This is permitted as the current version of x/sys/windows is only expected to be used with currently supported versions of Go.
