a compiler from a subset of Scheme into X64

YScheme - an experimental compiler for Scheme

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.
