native x86 backend

API redesign in preparation complete, initial tests on native factorial and closures working.

fasl/image files

sexp_copy_context() can form the basis for images, FASL for arbitrary modules will need additional help with resolving external references.

optional image loading on startup

State “DONE” from “TODO” [2011-11-10 Thu 20:44]

static image compiled into library

With this you’ll be able to run Chibi without any filesystem.

external tool to compact and optimize images

The current GC is mark&sweep, which can cause fragmentation, but we can at at least compact the initial fixed image.

fasl versions of modules

Important for large applications, and fast loading of script with many dependencies.

compiler optimizations

constant folding

State “DONE” [2009-12-16 Wed 23:25]

simplification pass, dead-code elimination

State “DONE” [2009-12-18 Fri 14:14]

This is important in particular for the output generated by syntax-rules.

lambda lift

The current closure representation is not very efficient, so this would help a lot.

inlining (and disabling primitive inlining)

Being able to redefine procedures is important though.

unsafe operations

Possibly, don’t want to make things too complicated or unstable.

plugin infrastructure

unicode

State “DONE” from “TODO” [2010-07-11 Sun 23:58]

Supported with UTF-8 strings, string-ref is O(n) and string-set! may need to reallocate the whole string. string-cursor-ref can be used for O(1) string access.

threads

State “DONE” from “TODO” [2010-07-11 Sun 15:31]

VM now supports an optional hook for green threads, and a SRFI-18 interface is provided as a separate module. I/O operations will currently block all threads though, this needs to be addressed.
