昨天为机器码编译程序写了个专用的unit test框架，今天用中间语言在这个框架上写了个程序。程序将12个字符串连接起来，然后跟另外一个字符串进行比较，如果相等返回true。当然程序如果返回false了，要么就是程序有问题，要么就是编译器有问题。当然现在是测试通过了。程序如下：
1 CONSTANT
2 STR1 stra:a
3 STR2 stra:bc
4 STR3 stra:def
5 STR4 stra:ghij
6 STR5 stra:klmno
7 STR6 stra:pqrstu
8 STR7 stra:vwxyzAB
9 STR8 stra:CDEFGHIJ
10 STR9 stra:KLMNOPQRS
11 STR10 stra:TUVWXYZabc
12 STR11 stra:defghijklmn
13 STR12 stra:opqrstuvwxyz
14 STRX stra:abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
