Subject: GNU Mes 0.18 released <#secure method=pgpmime mode=sign> We are pleased to announce the release of GNU Mes 0.18, representing 83 commits over 8 weeks. Mes is now bringing a Reduced Binary Seed bootstrap to GuixSD; the size of bootstrap binaries has been halved and no regular toolchain binaries are used as binary seeds (i686-linux and x86_64-linux only). MesCC has been refactored to use an abstracted assembly language and can now (cross-)build x86_64 binaries. Next targets: - reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source - revive Gash/Geesh and use it to decimate the remaining bootstrap binary seeds - and/or otherwise reduce the bootstrap binaries - ARM, the Hurd? Packages are available from Guix's core-updates-next branch. * About GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GuixSD[2] and potentially to any other interested GNU/Linux distribution, and aims to help create a full source bootstrap as part of the bootstrappable builds[3] effort. It consists of a mutual self-hosting Scheme interpreter written in ~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme. This mes.c is being simplified[4] to be transpiled by M2-Planet[5]. The Scheme interpreter (mes.c) has a Garbage Collector, a library of loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS [portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test suite just barely enough to support a simple REPL and simple C-compiler: MesCC. Mes+MesCC can compile an only lightly patched TinyCC[9] that is self-hosting. Using this tcc and the Mes C library we now have a Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5, binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap GuixSD for i686-linux and x86_64-linux. Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John McCarthy page 13, GNU Guix's source/binary packaging transparency and Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler. * Download git clone git://git.savannah.gnu.org/mes.git Here are the compressed sources and a GPG detached signature[*]: https://ftp.gnu.org/gnu/mes/mes-0.18.tar.gz https://ftp.gnu.org/gnu/mes/mes-0.18.tar.gz.sig Use a mirror for higher download bandwidth: https://ftpmirror.gnu.org/mes/mes-0.18.tar.gz https://ftpmirror.gnu.org/mes/mes-0.18.tar.gz.sig Here are the MD5 and SHA1 checksums: f9f901f175fbc8a5a3d90c9c551ccc8c mes-0.18.tar.gz 4f7612731a745ebb806548186453d55e0d0bf217 mes-0.18.tar.gz [*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify mes-0.18.tar.gz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273 and rerun the 'gpg --verify' command. Mes runs from the source tree and can also be built, packaged and installed in Guix[SD] from a git checkout by running guix package -f .guix.scm * Get informed, get involved Join #bootstrappable on irc.freenode.net. * Changes in 0.18 since 0.17.1 ** Core *** Mes/MesCC now supports x86_64. *** Mes/MesCC now brings a Reduced Binary Seed bootstrap to GuixSD. ** Language *** fold-right now supports 3 lists. ** MesCC *** MesCC now supports x86_64 (also as cross build), using -m 64. *** Mes C Library now has better support for bootstrapping gcc-3.0. *** Mes C test suite now has 178 tests; 74 tests were added. *** MesCC has been refactored to support use an abstracted assembly language. *** MesCC now uses Nyacc 0.86.0. ** Noteworthy bug fixes *** scaffold/tests/7s-struct-short.c has been fixed. * Changes in 0.17.1 since 0.17 ** MesCC *** Mes C Library has now been exploded into a separate C file per function. *** Mes C Library now bootstraps glibc-2.16.0, binutils-2.20.1, gcc-4.7.4. *** Mes C Library now supports compiling make-3.82. *** Mes C Library now supports compiling diffutils-2.7. *** Mes C Library now supports x86_64. **** 7 new functions chdir, clock_gettime, closedir, execl, opendir, readdir, time. **** 5 new stubs getlogin, setlocale, setvbuf, sigaddset, sigblock. ** Noteworthy bug fixes *** qsort can now handle lists with duplicate entries.
