调用linux system call

.section .rodata

output:

        .string  "Hello, World/n"

.section .text

.globl _start

       nop

       movl $4, %eax

       movl $1, %ebx

       movl $output, %ecx

       movl $13, %edx

       int $0x80

       movl $1, %eax

       movl $0, %ebx

       int $0x80

使用c的函数printf

.section .rodata

output:

        .string "Hello, World/n"

.section .text

.globl _start

         nop

         pushl $output

         call printf

         addl $4, %esp

         pushl $0

         call exit
