ARM指令TEXTAREA是什么意思? [复制链接]

TEXTAREA  ;请问这句是什么意思
IMPORT  main

草履虫

顾名思义，text area
汇编文档中有讲述这个东西

lottery009

翻译过来时text的area  哈哈

离开水的螃蟹

@textarea
。。。。

@endarea
一般会合在一起用，标示代码域吧

taotao39329112

AREA sectionname {} {}
其中， sectionname 是所定义的代码段或者数据的名称。
        text表示C语言编译器产生的代码段或者与C语言库相关的代码段。

顶楼上，不过这些你也不必要知道它的具体含义的啊

表示是代码段(域)，可能是告诉编译器的
