问题描述
我一直用汇编级编程最近，我能够用NASM的装配水平code转换为机器级code或并从中提取十六进制code，但如何是逆可能吗？我需要写与正在只给出了十六进制二进制可执行文件。我需要转换以下十六进制<$c$c>7a\\x65\\x00\\x5f\\x73\\x74\\x61\\x72\\x74\\x00\\x5f\\x5f\\x62\\x73\\x73\\x5f\\x73\\x74\\x61\\x72\\x74\\x00\\x5f\\x65\\x64\\x61\\x74\\x61\\x00\\x5f\\x65\\x6e\\x64\\x00一个可执行的，我该怎么做呢？
I have been working with assembly level programming lately and I am able to convert the assembly level code to the machine level code using nasm or as and extract the hex code from it, But how is the inverse possible ? I need to write binary executable files with only the hex being given. I need to convert the following hex 7a\x65\x00\x5f\x73\x74\x61\x72\x74\x00\x5f\x5f\x62\x73\x73\x5f\x73\x74\x61\x72\x74\x00\x5f\x65\x64\x61\x74\x61\x00\x5f\x65\x6e\x64\x00 to an executable, How do I do it ?
推荐答案
A.S：
.globl _start
_start:
.byte 0x7a,0x65,0x00,0x5f,0x73,0x74,0x61,0x72,0x74,0x00,0x5f,0x5f,0x62,0x73,0x73,0x5f,0x73,0x74,0x61,0x72,0x74,0x00,0x5f,0x65,0x64,0x61,0x74,0x61,0x00,0x5f,0x65,0x6e,0x64,0x00
GNU工具链的命令
gnu toolchain commands
as a.s -o a.o
ld a.o -o a

NASM语法：
global _start
_start:
db 0x7a,0x65,0x00,0x5f,0x73,0x74,0x61,0x72,0x74,0x00,0x5f,0x5f,0x62,0x73,0x73,0x5f,0x73,0x74,0x61,0x72,0x74,0x00,0x5f,0x65,0x64,0x61,0x74,0x61,0x00,0x5f,0x65,0x6e,0x64,0x00
