;; Commentary:
;;
;; Alphabetically and chronologically, Chez comes before Racket.
;;
;; The bootstrapping paths for Chez Scheme and Racket are closely
;; entwined. Racket CS (the default Racket implementation) is based on (a fork
;; of) Chez Scheme. Racket's variant of Chez Scheme shares sources for
;; nanopass and stex with upstream Chez Scheme.
;;
;; Racket's variant of Chez Scheme can be bootstrapped by an older Racket
;; implementation, Racket BC, which can be bootstrapped from C. Porting that
;; code to work with upstream Chez Scheme (or finding an old version that
;; does) is our best hope for some day bootstrapping upstream Chez Scheme from
;; source.
;;
;; Putting the relevant definitions together in this module avoids having to
;; work around dependency cycles.
;;
;; Anatomy of Racket:
;; ------------------
;;
;; The main Racket Git repository (<https://github.com/racket/racket>) is
;; organized broadly like this:
;;
;;     .
;;     ├── Makefile
;;     ├── pkgs/
;;     └── racket/
;;         ├── collects/
;;         └── src/
;;             ├── configure
;;             ├── Makefile.in
;;             ├── bc/
;;             ├── cs/
;;             ├── ChezScheme/
;;             └── ...
;;
;; The 'racket/src/' directory contains the source of the runtime system, core
;; compiler, and primitives for the major Racket implementations: this layer
;; is called the ``Racket VM''. It is basically a normal autotools
;; project. (Even when Racket VM implementations use components implemented in
;; Racket, they are compiled in special modes to produce VM primitives.)
;; (There are or have been experimental Racket VM implementations elsewhere,
;; e.g. <https://github.com/pycket/pycket>.)
;;
;; The 'racket/collects/' directory contains ``built in'' Racket libraries
;; that are not part of any package, including the implementation of
;; 'racket/base': in particular, it must contain enough to implement `raco pkg
;; install'. It is theoretically possible to use the Racket VM layer without
;; the main collections, but it is not stable or useful.
;;
;; The 'pkgs/' directory contains Racket packages that are especially closely
;; tied to the implementation of the Racket VM, including 'compiler-lib',
;; 'racket-doc', and 'racket-test'. Some of these packages depend on Racket
;; packages that are developed in other Git repositories, predominantly but
;; not exclusively under the 'racket' GitHub organization. Conversely, not all
;; of the packages developed in the main Git repository are part of the main
;; Racket distribution.  (Additionally, components of the Racket VM that are
;; implemented in Racket can be installed as packages, mostly for ease of
;; development.)
;;
;; The top-level 'Makefile' is more like a directory of scripts: it has
;; convienience targets for developing Racket, and it cooperates with the
;; 'distro-build' package to assemble custom Racket distributions. It is not
;; part of Racket source distributions: the root of a source distribution is
;; basically 'racket/src' with some extra package sources and configuration
;; added.
;;
;; A ''minimal Racket'' installation includes two packages: 'base', which is a
;; sort of bridge between the current ``built-in'' collections and the package
;; system's model of dependencies, and 'racket-lib', which, for installations
;; that can not rely on a system package manager, pulls in the SQLite and
;; OpenSSL shared libraries as platform-specific dependencies for use by the
;; ``built-in'' collections.
;;
;; The main Racket distribution consists of installing the 'main-distribution'
;; package and all of its dependencies.
;;
;; The default mode when building Racket (or installing it with the released
;; installers) is an ``in-place build'', which produces a self-contained,
;; relocatable, roughly FHS-like directory. (Racket also supports
;; ``Unix-style'' installations, which rearrange the parts of an in-place
;; build into Racket-specific subdirectories and generally tries to work for
;; installation into an FHS-based system.) Certain tools, e.g. 'distro-build'
;; and 'raco cross', are able to work with an in-place Racket build.
;;
;; This file defines the packages 'racket-vm-cgc', 'racket-vm-bc', and
;; 'racket-vm-cs'. All three are in-place builds of 'racket/src/' and
;; 'racket/collects/' and are installed to 'opt/racket-vm/' in the store
;; output. The function 'racket-vm-for-system' returns the recomended Racket
;; VM package for a given system.
;;
;; The file 'racket.scm' builds on these packages to define 'racket-minimal'
;; and 'racket' packages. These use Racket's support for ``layered
;; installations'', which allow an immutable base layer to be extended with
;; additional packages. They use the layer configuration directly provide
;; ready-to-install FHS-like trees, rather than relying on the built in
;; ``Unix-style install'' mechanism.
;;
;; Bootstrapping Racket:
;; ---------------------
;;
;; Here's how bootstrapping Racket works:
;;
;;   - Racket BC [CGC] can be built with only a C compiler (except for
;;     one caveat discussed below).
;;   - Racket BC [3M] needs an existing Racket to run "xform",
;;     which transforms its own C source code to add additional annotations
;;     for the precise garbage collector.
;;   - Racket CS needs (bootfiles for) Racket's fork of Chez Scheme.
;;     It also needs an existing Racket to compile Racket-implemented
;;     parts of the runtime system to R6RS libraries.
;;   - Chez Scheme also needs bootfiles for itself, but Racket can simulate
;;     enough of Chez Scheme to load Racket's fork of the Chez Scheme compiler
;;     purely from source into Racket and apply the compiler to itself,
;;     producing the needed bootfiles (albeit very slowly).
;;     Any variant of Racket since version 7.1 can run the simulation.
;;
;; So, we build CGC to build 3M to build bootfiles and CS.
;;
;; (Note: since the CGC variant is basically only for bootstrapping, we
;; often use "BC" to mean "3M", consistent with `(banner)` and the
;; suffixes used on executables when more than one variant co-exists.)
;;
;; One remaining bootstrapping limitation is that Racket's reader, module
;; system, and macro expander are implemented in Racket. For Racket CS,
;; they are compiled to R6RS libraries as discussed above. This note from the
;; README file applies to all such subsystems:
;;
;;     The Racket version must be practically the same as the current Racket
;;     verson, although it can be the Racket BC implementation (instead of
;;     the Racket CS implementation).
;;
;;     Unlike Chez Scheme boot files, the files generated in "schemified"
;;     are human-readable and -editable Scheme code. That provides a way
;;     out of bootstrapping black holes, even without BC.
;;
;; However, other Racket subsystems implemented in Racket for Racket CS
;; use older C implementations for Racket BC, whereas the reader, expander,
;; and module system were completely replaced with the Racket implementation
;;
;; For Racket BC, the compiled "linklet" s-expressions (primitive modules)
;; are embeded in C as a static string constant. Eventually, they are further
;; compiled by the C-implemented Racket BC bytecode and JIT compilers.
;; (On platforms where Racket BC's JIT is not supported, yet another compiler
;; instead compiles the linklets to C code, but this is not a bootstrapping
;; issue.)
;;
;; Code:

Type reconstruction during optimization (especially for safe code)

Parallel garbage collection, in-place garbage collection for old-generation

requires ``bootfiles'' containing the Scheme-implemented portions compiled for
the current platform.  (Chez can then cross-compile bootfiles for all other
supported platforms.)

The Racket package @code{cs-bootstrap} (part of the main Racket Git
repository) implements enough of a Chez Scheme simulation to load the Chez
Scheme compiler purely from source into Racket and apply the compiler to
itself, thus bootstrapping Chez Scheme.  Bootstrapping takes about 10 times as
long as using an existing Chez Scheme, but @code{cs-bootstrap} supports Racket
7.1 and later, including the Racket BC variant.

Note that the generated bootfiles are specific to Racket's fork of Chez
Scheme, and @code{cs-bootstrap} does not currently support building upstream
Chez Scheme.")))
