For this case:
/opaque/file1.go:

Details

package opaque

var hiddenBias = 11

type hidden struct {
	base int
}

func (h *hidden) secret(n int) int {
	return h.base + n + hiddenBias
}

func (h *hidden) Mirror(n int) int {
	return h.secret(n)
}

func NewOpaque(v int) any {
	return &hidden{base: v}
}

main.go:

Details

package main

import (
	"example.com/methodbynamecases/crosspkg_hidden_concrete/opaque"
)

func main() {
	v := opaque.NewOpaque(7)
	println(v)
}

针对这个用例，符号数量实际没有变化，变化的是符号大小，实际起作用的应该是函数内部的优化而不是死代码消除。当前lto优化等级为O0. 实际运行pass如下：

 Running pass 1 WholeProgramDevirtPass on [module]
 Running pass 2 LowerTypeTestsPass on [module]
 Running pass 3 LowerTypeTestsPass on [module]
 Running pass 4 EliminateAvailableExternallyPass on [module]
 Running pass 5 GlobalDCEPass on [module]

但是整体看运行的pass, codegen相关的pass其实有很多都会被运行，这些中也包含有较多的优化，原因是lto的优化等级需要区分中端和后端（codegen）的优化等级，codegen优化等级默认为O2：

所以针对这个用例，二进制大小的缩减主要来自于后端优化，并不是lto本身的优势，后续该编译优化可以开启，但当前issue需要更关注基于lto机制所能实现的优化。

后端优化等级为O0时的pass：
