问题描述

I am tasked to convert my assembly program which uses NASM to GAS. Unfortunately there are lots of mismatched statements. I have converted some of them but I am still having trouble on how to convert this statement

min resw 1

推荐答案

保留一个单词(初始值设定为0)非常简单:

Reserving one word (with an initializer of 0) is pretty easy:

min:    .word    0

对于x86，.word是16位.对于其他尺寸:.byte，.long，.quad.

For x86, .word is 16-bit. For other sizes: .byte, .long, .quad.

如果您想保留一大块(例如50个单词)，请使用.fill或.space指令:

If you wanted to reserve a large chunk, say 50 words, use the .fill or .space directives:

buff1:  .fill    50, 1, 0     # count, size, value
buff2:  .space   50, 0        # count (bytes), value (defaults to 0)

对于重复模式大于1个字节的初始化程序， .dcb.size 带有值和长度:

For initializers with a repeating pattern wider than 1 byte, .dcb.size takes a value and length:

int_array:  .dcb.l  50, 12345       # 32-bit integer 12345 repeated 50 times
