xtls and sidh related bugs

[advancedwebdeveloper]

Hi.
I caught such bugs, related to two dependency packages:

~/go_projects/v2ray-core$ go test ./...

Go 1.15.2 的 internal/cpu 存在此问题吗？XTLS 的 go/cpu 是复制它的。

I am not understanding your language.
Please explain in English. Tnx

Is there the same problem with internal/cpu of Go 1.15.2? Cause go/cpu of XTLS was copied from it.

I am using Intel Core2 Quad CPU Q9400

https://github.com/XTLS/Go now imports "golang.org/x/sys/cpu" in place of "github.com/xtls/go/cpu".

Might have solved this problem in passing, but if not, there's nothing more I can do... Besides, sidh's problem is out of my control.
