Currently, cgo converts integer macros into int64 if it's possible. As a result, some macros which satisfy math.MaxInt64 < x <= math.MaxUint64 will lose their original values. This CL introduces the new probe to check signs, so we can handle signed ints and unsigned ints separately. Fixes #20369 Change-Id: I002ba452a82514b3a87440960473676f842cc9ee Reviewed-on: https://go-review.googlesource.com/43476 Reviewed-by: Ian Lance Taylor <iant@golang.org> Run-TryBot: Ian Lance Taylor <iant@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>
