本文目录前言一、Hello Global Variable二、编译三、运行四、总结 前言在此记录下用LLVM创建全局变量(Global Variable)的过程,以备查阅。开发环境的配置请参考第一章 《LLVM系列第一章:编译LLVM源码》。全局变量(Global Variable)是在一个模块(Module)之内全局可见的变量,也就是说模块内所有的函数都能用它。LLVM提供...
2、Dim t, i&, a :声明变量t,a 均为可变型变量,i为长整型变量。 3、t = Timer :把系统的时间赋给变量t。 4、For i = 1 To 1000000 :从1 到 1000000循环。 5、a = a + i :把a+i的值赋给变量a,实际上是一个累加的过程。 6、MsgBox Timer - t & "秒" :利用消息框显示现在的时间减去前...
