将优化标志传递给Go编译器? [英] Passing an optimization flag to a Go compiler?

问题描述

要编译Go程序，请键入 go build myprogram.go ，是否可以传递优化标志，或者始终以相同的方式编译代码?我说的是速度优化，代码大小优化或其他优化.

To compile a Go program you type go build myprogram.go, can you pass an optimization flags along or the code is always compiled in the same way? I am talking about speed optimizations, code size optimizations or other optimizations.

我知道如果您使用 gccgo 只是通过 -O2 或 -O0 ，但是我的问题是关于官方Go编译器去.

I know if you use gccgo you just pass -O2 or -O0 but my question is about an official Go compiler go.

推荐答案

实际上没有明确的标记，此Go Wiki

Actually no explicit flags, this Go wiki page lists optimizations done by the Go compiler and there was a discussion around this topic in golang-nuts groups.

您可以在Go gc编译器中关闭优化和内联功能以进行调试.

You can turn off optimization and inlining in Go gc compilers for debugging.

-gcflags '-N -l'

• -N :禁用优化
• -l <​​/code>:禁用内联
