p423-compiler

Archive repo of a Scheme to x86-64 compiler in Scheme.

Supports:

  • closures
  • first-class procedures
  • side effects with set!
  • closure conversion, tail-call elimination, branch predication, constant folding, dead-code elimination, and... several other optimizations

The supported BNF is listed as below.

Program   ::= Expr
Expr      ::= Constant
            | Var
            | (quote Datum)
            | (if Expr Expr)
            | (if Expr Expr Expr)
            | (and Expr *)
            | (or Expr *)
            | (begin Expr * Expr)
            | (lambda (Var *) Expr +)
            | (let ([Var Expr] *) Expr +)
            | (letrec ([Var Expr] *) Expr +)
            | (set! Var Expr)
            | (prim Expr *)
            | (Expr Expr *)
Datum     ::= Constant | (Datum *) | #(Datum *)
Constant  ::= fixnum | () | #t | #f
Var       ::= an arbitrary symbol
