问题描述

我在MIPS是新尝试使用自学<一个href=\"https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CD8QFjAA&url=http://www.cse.buffalo.edu/~shambhu/cse34113/handouts/britton-mips-tutorial.pdf&ei=w5f0UYLgJJC08QSl8YHQBg&usg=AFQjCNG6BVXpFK5nMjqwbFJviy9XdSUI6g&sig2=z0KJQBDGPftOg4TyHHrhqw&bvm=bv.49784469,d.eWU\"相对=nofollow>这本书。我想了解的数据和指令是什么这三者之间的区别:

 列表:.word 0:3
清单:.word 3
清单:.word

但我没有找到任何明确的文件/参考。

感谢您。


解决方案

 列表:.word 0:3

会预留3个字,并设置每个为值 0 。这将类似于

  INT表[3] = {0,0,0};

或者

 清单:12。空间

(在这种情况下,该值为隐0)

在0'0:3'可以有很好是任何其它值。例如:

 列表:.word'X':3
# 要么
清单:.word 88:3

当缺少的元素数,它只是在字的值

 列表:.word 3

这是类似

  INT表= 3;

最后一个,

 列表:.word

将有可能导致装配抱怨为丢失的操作。

I'm new in MIPS and trying to teach myself using this book. I'm trying to learn data directive and what are the difference between these three :

list:   .word 0:3
list:   .word 3
list:   .word

But I didn't find any clear document/reference.

Thank you.

解决方案
list:   .word 0:3

Will reserve 3 words and set each to the value 0. This would be similar to:

int list[3] = {0, 0, 0};

Or

list:   .space 12

(In which case, the value is implicitly 0).

The 0 in '0:3' could have very well be any other value. For example:

list:   .word 'X':3
# or
list:   .word 88:3

When the number of elements is missing, it's simply the value of the word

list:   .word 3

Which is similar to

int list = 3;

The last one,

list:   .word

Will likely cause assemblers to complain for the missing operand.
