Linux发行版知识普及：三个版本的CPUID

#cpuid.s show extract the processor vendor ID
.section .data
output:
.ascii "the processor vendor ID is 'XXXXXXXXXXXX'\n"
.section .text
.globl main
main:
movl $0, %eax
cpuid
movl $output, %edi
movl %ebx, 28(%edi)
movl %edx, 32(%edi)
movl %ecx, 36(%edi)
movl $4, %eax
movl $1, %ebx
movl $output, %ecx
movl $42, %edx
int $0x80
movl $1, %eax
movl $0, %ebx
int $0x80

# cpuidinlib.s show extract the processor vendor ID using library
.section .data
output:
.asciz "the processor vendor ID is %s\n"

.section .bss
.lcomm buffer, 12

.section .text
.globl _start
_start:
movq $0, %rax
cpuid
movq $buffer, %rdi
movl %ebx, (%rdi)
movl %edx, 4(%rdi)
movl %ecx, 8(%rdi)

movq $output, %rdi
movq $buffer, %rsi
xorq %rax, %rax
call printf
movq $0, %rdi
xorq %rax, %rax
call exit
不过上面有一个问题
printf("%s", str);
