golang: How to check whether a function is inlined

main.go

package main

import "fmt"

func main() {
	x := 40
	y := 2
	res1 := inlinedFunc(x, y)
	fmt.Println(res1)
	res2 := notinlinedFunc(x, y)
	fmt.Println(res2)
}

func inlinedFunc(x int, y int) int {
	return x + y
}

func notinlinedFunc(x int, y int) int {
	for i := 0; i < x; i++ {
		x += y
	}
	return x
}

Makefile

all:
	make build
	make objdump

build:
	go build -gcflags -m main.go

objdump:
	go tool objdump -s "main.main" main | grep CALL
