go_unused_reassignment(未完成)

再代入後に使用されていないものと、それを取り除いた時に使用されていないものを指摘する静的解析ツール

適用前

var f = func(p int) int{
	a := 987 + temp(p)
	for i:=0;i<10;i++ {
		a += i // want "Resubstitutioned before used"
	}
	b := 12345
	a,b = b,a
	a += 10
	if p == 10 {
		p = 54321 // want "Resubstitutioned before used"
	}else {
		a = 39475
	}

	if p == 100 {
		p = 54321 // want "Resubstitutioned before used"
	}else {
		a = 39475
	}

	p = 12340000 // want "Resubstitutioned before used"
	p = a + b
	a = 12345 // want "Resubstitutioned before used"
	a += 20 // want "Resubstitutioned before used"
	a += 20 // want "Resubstitutioned before used"
	a = a + 5124 // want "Resubstitutioned before used"
	a += 30 // want "Resubstitutioned before used"
	a += 40 // want "Resubstitutioned before used"
	return p
}

適用後

var f = func(p int) int{
	a := 987 + temp(p)
	b := 12345
	a,b = b,a
	a += 10
	if p == 10 {
	}else {
		a = 39475
	}

	if p == 100 {
	}else {
		a = 39475
	}
	p = a + b
	return p
}
