==================================================== 现在开始测试GCJ 3.4 第一步,已经下载了 第二步, 解压到:E:\OpenSource\GCC3 ,可以看到有个gcc-3.4的目录 把 E:\OpenSource\GCC3\gcc-3.4\bin 这个目录加入到你的系统环境变量PATH当中 然后运行 gcj --help 可以看到帮助 再运行 gcj

所以我们只能讨论范围限制在某种特定机器上的某个编译器上.在这里,我们约定是x86/gcc3 (linux) 当返回值能容纳在一个寄存器中时, 通常都用一个寄存器返回.这是没有问题的.
