Subject: Mes 0.16 released I am pleased to announce the release of Mes 0.16, representing 27 commits over 2 weeks. A most annoying ELF header bug was fixed that suddenly had all Mes binaries segfault before entering `_start' on Linux 4.17 and later. We now have binutils-2.20.1 and gcc-4.1.0, both compiled with gcc-2.95.3 and glibc-2.2.5. This reduced-binary-seed bootstrap still depends on these bootstrap binaries: BOOTSTRAP-GUILE, flex, bash, bzip2, coreutils, diffutils, gawk, grep, gzip, make, sed, tar, on the small binary seeds: tinycc-seed, mescc-seed and on the mes.M1 ASCII seed. Next targets: - build a Gcc 4.7 and Glibc 2.23 - upstream the x86 Mes bootstrap to GuixSD - reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source - revive Gash: a posix shell for Guile to reduce the bootstrap binary dependencies - and/or otherwise reduce the bootstrap binary dependencies Packages are available from Guix's wip-bootstrap branch. * About Mes[0] aims to help create full source bootstrapping for GuixSD[1] as part of the bootstrappable builds[2] effort. It currently consists of a mutual self-hosting Scheme interpreter prototype written in C and a Nyacc-based C compiler written in Scheme. This C prototype is being simplified[3] to be transpiled by M2-Planet[4]. The Scheme interpreter prototype (mes.c) has a Garbage Collector, a library of loadable Scheme modules-- notably Dominique Boucher's LALR[5], Pre-R6RS portable syntax-case[6] with R7RS ellipsis, Matt Wette's Nyacc[7], Guile's PEG[8] --and test suite just barely enough to support a simple REPL and simple C-compiler: MesCC. Mes+MesCC can compile an only lighty 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-4.1.0. 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 https://gitlab.com/janneke/mes wget https://gitlab.com/janneke/mes/-/archive/v0.16/mes-0.16.tar.gz Mes runs from the source tree and can also be built, packaged and installed in Guix[SD] by the usual guix package -f guix.scm * Get informed, get involved Join #bootstrappable on irc.freenode.net. * Changes in 0.16 since 0.15 ** Core *** Support building with tcc, including Mes Lib C in-line assembly. *** core:execl now supports 1000 arguments. ** MesCC *** Mes Lib C now bootstraps glibc-2.2.5, binutils-2.20.1, gcc-4.1.0. *** MesCC binaries now run on Linux 4.17 too, i.e. survive Linus' new `sane mmap limits.' *** MesCC now runs with mescc-tools 0.5 (no = in long options). **** 3 new C test 88-strrchrc, 97-fopen.c, 98-fopen.c. ** Noteworthy bug fixes *** strrchr now stops when it reaches start of string. *** fopen now return 0 upon failure. Supports binutils' hack: fd=-2 means `cached'. *** vfprintf, vsprintf now support precision and width on integers strings better. *** fread now produces ungetc'd chars too. *** memcmp now supports comparing 0 bytes, supporting binutils. *** The unused ELF header data section, identical to the text section, has been removed.
