我如何执行这个汇编代码？

Question

I've written this simple code in JavaScript and use d8 to show the assembly code. Now, I want to execute that assembly code but I'm unable to do it.

Here's my code

print('Hello')

And this is the assembly I get from d8

--- Raw source ---
print('Hello');


--- Code ---
source_position = 0
kind = FUNCTION
compiler = full-codegen

Now I would like to execute that assembly code I get this error:

cc -s print.s

This is my print.s

You cannot take a snippet from a program with fixed pointers, copy-paste that and expect it to work.

Your snippet will never work.
It references absolute addresses that are only valid within the context of the original program it was executed in.
The next time the original program executes the addresses will likely be different because of ASLR, quite beside the fact that all programs in OSX must be relocatable; ie fixed addresses do not exist in OSX.
In any case you point to run-time code that is simply not present in your copy-paste snippet.

You need to learn how to write a stand-alone 'hallo world' assembly program.

There are 100's of tutorials detailing how to do this, eg: http://peter.michaux.ca/articles/assembly-hello-world-for-os-x

 hello.asm - a "hello, world" program using NASM section .text global mystart ; make the main function externally visible mystart: ; 1 print "hello, world" ; 1a prepare the arguments for the system call to write push dword mylen ; message length push dword mymsg ; message to write push dword 1 ; file descriptor value ; 1b make the system call to write mov eax, 0x4 ; system call number for write sub esp, 4 ; OS X (and BSD) system calls needs "extra space" on stack int 0x80 ; make the actual system call ; 1c clean up the stack add esp, 16 ; 3 args * 4 bytes/arg + 4 bytes extra space = 16 bytes ; 2 exit the program ; 2a prepare the argument for the sys call to exit push dword 0 ; exit status returned to the operating system ; 2b make the call to sys call to exit mov eax, 0x1 ; system call number for exit sub esp, 4 ; OS X (and BSD) system calls needs "extra space" on stack int 0x80 ; make the system call ; 2c no need to clean up the stack because no code here would executed: already exited section .data mymsg db "hello, world", 0xa ; string with a carriage-return mylen equ $-mymsg ; string length in bytes

If you want to write assembly code running under OSX you'll also need to learn how the OSX API works .
