vscode实现。

1、编写简单C语言程序hello.c：

#include int main(){int i=0;printf("%d\n",i);return 0;}

2、生成汇编文件：

终端输入gcc -S hello.c 就会生成hello.s

可添加asm插件，使汇编代码有颜色便于阅读。

.section__TEXT,__text,regular,pure_instructions.build_version macos, 10, 15sdk_version 10, 15, 6.globl_main ## -- Begin function main.p2align4, 0x90_main:## @main.cfi_startproc## %bb.0:pushq%rbp.cfi_def_cfa_offset 16.cfi_offset %rbp, -16movq%rsp, %rbp.cfi_def_cfa_register %rbpsubq$16, %rspmovl$0, -4(%rbp)movl$0, -8(%rbp)movl-8(%rbp), %esileaqL_.str(%rip), %rdimovb$0, %alcallq_printfxorl%ecx, %ecxmovl%eax, -12(%rbp) ## 4-byte Spillmovl%ecx, %eaxaddq$16, %rsppopq%rbpretq.cfi_endproc## -- End function.section__TEXT,__cstring,cstring_literalsL_.str: ## @.str.asciz"%d\n".subsections_via_symbols

3、生成二进制目标文件hello.o

终端输入gcc -c hello.c

4、生成二进制可执行文件prog

终端输入gcc -o prog hello.c sum.c

5、反汇编

终端输入objdump -d hello.o
