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

$ go version
go version devel +c4f87ed Tue Mar 26 02:20:09 2019 +0000 linux/amd64

Does this issue reproduce with the latest release?

Yes

What did you do?

I was playing around with the compiler to see what code it would produce under various situations.
After testing for a while, I found this case, where the code produced is a little weird:

package test

func test1() {
    return
}

func test2(k *int) {
    if k == nil {
        test1()
    }
}

What did you expect to see?

I expected the test2 function to compile to a simple return.

What did you see instead?

Instead, the following code was generated (notice the weird double jump):

        movq    "".k+8(SP), AX
        pcdata  $2, $0
        testq   AX, AX
        jeq     test2_pc11
test2_pc10:
        pcdata  $2, $-2
        pcdata  $0, $-2
        ret
test2_pc11:
        pcdata  $2, $0
        pcdata  $0, $1
        xchgl   AX, AX
        jmp     test2_pc10

Back in version go1.11, the code produced was a bare return, as I was initially expecting.
