<pre class="k9mail">We are pleased to announce the release of GNU Mes 0.18, representing<br>83 commits over 8 weeks.<br><br>Mes is now bringing a Reduced Binary Seed bootstrap to GuixSD; the<br>size of bootstrap binaries has been halved and no regular toolchain<br>binaries are used as binary seeds (i686-linux and x86_64-linux only).<br><br>MesCC has been refactored to use an abstracted assembly language and<br>can now (cross-)build x86_64 binaries.<br><br>Next targets:<br><br> - reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source<br> - revive Gash/Geesh and use it to decimate the remaining bootstrap<br> binary seeds<br> - and/or otherwise reduce the bootstrap binaries<br> - ARM, the Hurd?<br><br>Packages are available from Guix's core-updates-next branch.<br><br>* About<br><br> GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GuixSD[2] and<br> potentially to any other interested GNU/Linux distribution, and aims<br> to help create a full source bootstrap as part of the<br> bootstrappable builds[3] effort.<br><br> It consists of a mutual self-hosting Scheme interpreter written in<br> ~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.<br> This mes.c is being simplified[4] to be transpiled by M2-Planet[5].<br><br> The Scheme interpreter (mes.c) has a Garbage Collector, a library of<br> loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS<br> [portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test<br> suite just barely enough to support a simple REPL and simple<br> C-compiler: MesCC.<br><br> Mes+MesCC can compile an only lightly patched TinyCC[9] that is<br> self-hosting. Using this tcc and the Mes C library we now have a<br> Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5,<br> binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap GuixSD for<br> i686-linux and x86_64-linux.<br><br> Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John<br> McCarthy page 13, GNU Guix's source/binary packaging transparency and<br> Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.<br><br>* Download<br><br> git clone git://git.savannah.gnu.org/mes.git<br><br> Here are the compressed sources and a GPG detached signature[*]:<br> <a href="https://ftp.gnu.org/gnu/mes/mes-0.18.tar.gz">https://ftp.gnu.org/gnu/mes/mes-0.18.tar.gz</a><br> <a href="https://ftp.gnu.org/gnu/mes/mes-0.18.tar.gz.sig">https://ftp.gnu.org/gnu/mes/mes-0.18.tar.gz.sig</a><br><br> Use a mirror for higher download bandwidth:<br> <a href="https://ftpmirror.gnu.org/mes/mes-0.18.tar.gz">https://ftpmirror.gnu.org/mes/mes-0.18.tar.gz</a><br> <a href="https://ftpmirror.gnu.org/mes/mes-0.18.tar.gz.sig">https://ftpmirror.gnu.org/mes/mes-0.18.tar.gz.sig</a><br><br> Here are the MD5 and SHA1 checksums:<br><br> f9f901f175fbc8a5a3d90c9c551ccc8c mes-0.18.tar.gz<br> 4f7612731a745ebb806548186453d55e0d0bf217 mes-0.18.tar.gz<br><br> [*] Use a .sig file to verify that the corresponding file (without the<br> .sig suffix) is intact.
