这是比较接近王垠原始代码的一个版本。它的代码经常会lost in the future，所以我fork了一份。

王垠的放出来的代码是运行不了的，所以这里补全了一些东西，让它能够运行。

这些补全都是从网上收集的。相关版权的都属于各自原始出处。

文档来自于这里，根据代码来推测，作者可能当时跟王垠同班。

P423是Indiana大学王垠当时选的编译器的课程，这里和这里都能找到一些课程的代码。

这里有部分我翻译成中文的资料。

chez scheme有一个免费的解释器版本petite，去找到并下载。

cd yscheme
petite
(load "compiler.ss")
(test-one '(lambda (x) (+ x 1)))

可以看到最后的输出：

generate-x86-64:
    .globl _scheme_entry
_scheme_entry:
    pushq %rbx
    pushq %rbp
    pushq %r12
    pushq %r13
    pushq %r14
    pushq %r15
    movq %rdi, %rbp
    movq %rsi, %rdx
    leaq _scheme_exit(%rip), %r15
    movq %rdx, %rax
    addq $8, %rdx
    addq $2, %rax
    movq %rax, %rcx
    leaq L2(%rip), %rax
    movq %rax, -2(%rcx)
    movq %rcx, %rax
    jmp *%r15
L2:
    movq %r9, %rax
    addq $8, %rax
    jmp *%r15
_scheme_exit:
    popq %r15
    popq %r14
    popq %r13
    popq %r12
    popq %rbp
    popq %rbx
    ret

自己测试可以运行可以调用test-one函数。有一些参数是可以设置的，比如：

(tracer #f) 关闭中间过程的输出
(compiler-passes '(<spec> ...)) 设置运行的pass
(test-one '<program>) 测试一段代码

具体的可以去看driver.ss文件

This is the final submission for a compiler course I took from Kent Dybvig at Indiana University. The compiler compiles a significant subset of Scheme into X64 assembly and then links it with a runtime system written in C. I made attempts to simplify and innovate the compiler, so it is quite different from Kent's original design.

In Kent's words, I put myself into trouble each week by doing things differently and then get myself out of it. Sometimes I did better than his compiler, sometimes, worse. But eventually I passed all his tests and got an A+.

A notable thing of this compiler is its use of high-order evaluation contexts, an advanced technique used in CPS transformers, which resulted sometimes in much simpler and shorter code.
