asm
原文:https://pkg.go.dev/cmd/asm@go1.19.3
Overview 概述
Asm, typically invoked as “go tool asm”, assembles the source file into an object file named for the basename of the argument source file with a .o suffix. The object file can then be combined with other objects into a package archive.
asm
,通常以 “go tool asm
“调用,将源文件组装成一个对象文件,该文件以参数源文件的基本名称命名,并使用.o
后缀。之后,该对象文件可以与其他对象组合成一个包存档。
Command Line 命令行
Usage:
用法:
go tool asm [flags] file
The specified file must be a Go assembly file. The same assembler is used for all target operating systems and architectures. The GOOS and GOARCH environment variables set the desired target.
指定的 file
必须是一个Go汇编文件。所有的目标操作系统和体系结构都使用同一个汇编器。GOOS
和GOARCH
环境变量设置所需的目标。
Flags:
标志:
-D name[=value]
Predefine symbol name with an optional simple value.
Can be repeated to define multiple symbols.
=> 用一个可选的简单值预先定义符号名称。
可以重复定义多个符号。
-I dir1 -I dir2
Search for #include files in dir1, dir2, etc,
after consulting $GOROOT/pkg/$GOOS_$GOARCH.
=> 搜索dir1、dir2等地方的#include文件。
在查阅了$GOROOT/pkg/$GOOS_$GOARCH之后。
-S
Print assembly and machine code.
=> 打印汇编和机器代码。
-V
Print assembler version and exit.
=> 打印汇编程序版本并退出。
-debug
Dump instructions as they are parsed.
=> 在解析指令的过程中倾倒指令。
-dynlink
Support references to Go symbols defined in other shared libraries.
=> 支持对其他共享库中定义的 Go 符号的引用。
-gensymabis
Write symbol ABI information to output file. Don't assemble.
=> 将符号ABI信息写入输出文件。不要组装。
-o file
Write output to file. The default is foo.o for /a/b/c/foo.s.
=> 将输出写入文件。默认是/a/b/c/foo.s的foo.o。
-shared
Generate code that can be linked into a shared library.
=> 生成可以被链接到共享库中的代码。
-spectre list
Enable spectre mitigations in list (all, ret).
=> 在列表中启用spectre缓解措施(全部,ret)。
-trimpath prefix
Remove prefix from recorded source file paths.
=> 从记录的源文件路径中移除前缀。
Input language:
输入语言:
The assembler uses mostly the same syntax for all architectures, the main variation having to do with addressing modes. Input is run through a simplified C preprocessor that implements #include, #define, #ifdef/endif, but not #if or ##.
汇编器对所有的架构都使用相同的语法,主要的变化是与寻址模式有关。输入是通过一个简化的C预处理器运行的,它实现了#include、#define、#ifdef/endif,但没有#if或##。
