What did you do?
go build -o hello hello.go
go version -m hello
go build -buildmode pie -o hello-pie hello.go
go version -m hello-piehello.go:
package main
import "fmt"
func main() {
fmt.Println("yo")
}What did you expect to see?

I expected to see the -buildmode flag in the build settings. I can see that it is not added here:
