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.
