Write hello world on intel asm x64

section .data
msg db "Hello, world!", 0

section .text
global _start

_start:
mov rax, 1
mov rdi, 1
mov rsi, msg
mov rdx, 13
syscall

mov rax, 60
xor rdi, rdi

用asm输出hello world

在 x86 汇编语言中，你可以使用以下代码输出 "Hello, World!"：

section .data
    msg db 'Hello, World!',0

section .text
    global _start

_start:
    ; write function call
    mov eax, 4
    mov ebx, 1
    mov ecx, msg
    mov edx, 13
    int 0x80

    ; exit function call
    mov eax, 1
    xor ebx, ebx
    int 0x80

这段代码使用了 x86 汇编的两个系统调用：write 和 exit。 write 用于输出字符串，而 exit 用于终止程序。

NASM hello world

Sure! Here's an example of a NASM program that prints "Hello, World!" to the console:

section .data
    msg db 'Hello, World!', 0

section .text
    global _start

_start:
    ; write the message to stdout
    mov eax, 4
    mov ebx, 1
    mov ecx, msg
    mov edx, 13
    int 0x80

    ; exit the program
    mov eax, 1
    xor ebx, ebx
    int 0x80

This program uses the NASM syntax and Linux system calls. It first defines a `msg` variable in the `.data` section, which stores the string "Hello, World!". Then, in the `.text` section, it uses the `write` system call to print the message to the console. Finally, it uses the `exit` system call to terminate the program.

To assemble and run this program, you can save it to a file named `hello.asm` and use the following commands:

nasm -f elf hello.asm
ld -m elf_i386 -s -o hello hello.o
./hello

This will compile and run the NASM program, and you should see "Hello, World!" printed to the console.
