Ok, I write the fact which happened to make go1.16.3-plan9-amd64-bootstrap
from go1.16.3-plan9-amd64-bootstrap.tbz:
-----from here----
I made first go1.16.3-plan9-amd64-bootstrap.tar on this Plan9.
cpu% cat go1.16.3-plan9-amd64-bootstrap.tar|{cd /sys/lib/go; tar xT}

// Format returns a string representation of the expression.
func Format(fset *token.FileSet, x ast.Expr) string {
var b bytes.Buffer
printer.Fprint(&b, fset, x)
return b.String()
}
// HasSideEffects reports whether evaluation of e has side effects.
func HasSideEffects(info *types.Info, e ast.Expr) bool {
safe := true
ast.Inspect(e, func(node ast.Node) bool {
switch n := node.(type) {
case *ast.CallExpr:
typVal := info.Types[n.Fun]
switch {
case typVal.IsType():
// Type conversion, which is safe.
case typVal.IsBuiltin():
// Builtin func, conservatively assumed to not

safe = false
return false
default:

return false
}
case *ast.UnaryExpr:
if n.Op == token.ARROW {

return false

return true
})
return !safe
}

func Unparen(e ast.Expr) ast.Expr {

if !ok {
return e
}
e = p.X
}
}

cpu% lc /sys/lib/go/go-plan9-amd64-bootstrap
bin pkg src test
--------to here------
I, then, make go-plan9-amd64-bootstrap file tree on Linux, and copy it to
/sys/lib/go.
>From the procedures above, I thought go-plan9-amd64-bootstrap.tbz was built on
>a
certain system other than Plan9.
