その名の通り、mincamlにcopying gcを実装しました。
一応元々のテストプログラムはバグらずに動きます。
メモリの大きさは直接書き換えてください。確かテスト用の値がそのまま入っているのでかなり小さいはず。
あとx86にのみ実装してあって、おまけにx86以外のアーキテクチャは動きませんので注意。

memo:
* closureのmalloc、staticにわかるのに呼び出しに頼るのは渋い気がしなくもない
* calling conventionにのっとる
* saveのところでgcしても領域が確保できないコーナーケースは捨てている
* float saveの処理がまだ怪しい気がする（死んでいる変数でもgcに捕まる)
* 説明とかちゃんとしたい

下が本来のreadmeです。

An educational compiler for a minimal subset of OCaml, written in
~2000 lines of OCaml.  For details, see:

http://esumii.github.io/min-caml/ (Japanese Web page)
http://esumii.github.io/min-caml/jpaper.pdf (Japanese academic paper)
http://esumii.github.io/min-caml/index-e.html (English Web page)
http://esumii.github.io/min-caml/paper.pdf (English academic paper)

1. Install OCaml (http://caml.inria.fr/) if you haven't

2. Download (and expand) MinCaml, e.g.
   git clone https://github.com/esumii/min-caml.git

3. cd min-caml/

4. Execute ./to_x86 for x86
   (or ./to_sparc for SPARC, ./to_ppc for PowerPC)

5. make

6. If you like, try the ray tracer

     cd min-rt/ ; make

   though it takes time because of OCaml bytecode (for testing by
   comparison), not MinCaml

[FAQ 1] Is there an x86_64 version?

[A] There is, but it is left as an exercise for students and _not_
included in this distribution.

[FAQ 2] Is there a version that emits C code?

[A] See above.

[Updates on October 9, 2013]

- Moved from SourceForge https://sourceforge.net/p/min-caml/code/ to
  GitHub https://github.com/esumii/min-caml

- Merged the Mac OS patch by shinh
  https://twitter.com/shinh/status/322043108021907458

[Update on July 24, 2012]

- 32-bit x86 (with SSE2, that is, Pentium IV or later) is now
  supported (on Linux and Cygwin); execute ./to_x86 before make.

[Updates on September 17, 2008]

- PowerPC is now supported (in addition to SPARC), thanks to
  Ms. Masuko and Prof. Asai in Ochanomizu University.  You _must_
  execute either ./to_ppc or ./to_sparc _before_ make.

- The register allocator now uses a simpler algorithm.  It omits the
  backtracking (ToSpill and NoSpill) in previous versions.
