您好，对于如下面图片所示的源代码，出现了似乎不能编译的情况（见第二张图片）


我也没有修改您的代码，直接拿来跑一下。看这情况应该是语法分析部分出了问题也或许是其他方面我的原因，想问一下您有没有解决的思路。

请问一下您采用的IR是何种类型？感觉更偏向汇编一点，后面的优化思路又是怎样的呢？
还有就是语义分析是在哪里做的？
我正在学习编译原理并尝试实现sysY的编译器，如蒙指教，不胜感激！

I find that const value can be changed in your program!!!

const int a=6;
int main()
{
    a=4;
}

it can be compile successfully.
by the way,I want to ask a question, what's the meaning of PHI_MOV ,PHI_block and the fake(do) while generating the irs of whilestatement.
Basically,I even not understand clearly the use of PHI_MOV,dose it have something to do with phi node or SSA?
I would be grateful for you answer.

Hello, I found your previous project when I was learning compiler, and I would like to ask if there are supporting documents for me to learn more conveniently. If so, I wonder if you can provide them? Thank you very much.
