Date: Sat, 19 Feb 2022 01:42:24 -0500
The Racket variant of Chez Scheme can be used to support platforms that
are not yet supported by upstream Chez Scheme.
* gnu/packages/chez-and-racket-bootstrap.scm (unpack-nanopass+stex):
(chez-scheme-for-racket):
(chez-scheme-for-racket-bootstrap-bootfiles): New variables.
(chez-scheme)[arguments]<#:phases>: Adapt 'unpack-nanopass+stex' phase
to use the eponymous new variable.

+Unboxed floating-point arithmetic and flvectors

+Type reconstruction during optimization (especially for safe code)
+@item
+Continuation attachments
+@item
+Parallel garbage collection, in-place garbage collection for old-generation
+objects (instead of always copying), and reachability-based memory
+accounting
+@item
+Ordered finalization, immobile (but collectable) objects, weak/ephemeron
+generic hash tables, and reference bytevectors
+@item
+Faster multiplication and division for large exact numbers

+ (synopsis "Chez Scheme bootfiles bootstrapped by Racket")
+ (description "Chez Scheme is a self-hosting compiler: building it
+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.")))
