Subject: GNU Mes 0.23 released
|
|
|
|
<#secure method=pgpmime mode=sign>
|
|
|
|
We are happy to announce the release of GNU Mes 0.23, representing 125
|
|
commits over one year by four people.
|
|
|
|
Mes was ported to ARM and can now be used in the GNU Guix Reduced Binary
|
|
Seed bootstrap as described here
|
|
|
|
https://guix.gnu.org/blog/2020/guix-further-reduces-bootstrap-seed-to-25/
|
|
|
|
and now also for armhf-linux and aarch-linux. Work to integrate this
|
|
into Guix is ongoing: tinycc and gcc-core-2.95.3 have been built.
|
|
|
|
We are excited that the Nlnet Foundation is now sponsoring this work!
|
|
|
|
Enjoy,
|
|
Janneke and Danny.

* About
|
|
|
|
GNU Mes[0] is a Scheme interpreter and C compiler for bootstrapping the
|
|
GNU System. Since version 0.22 it has again helped to halve the size of
|
|
opaque, uninspectable binary seeds that are currently being used in the
|
|
Reduced Binary Seed bootstrap[1] of GNU Guix[2]. The final goal is to
|
|
help create a full source bootstrap as part of the bootstrappable
|
|
builds[3] effort for UNIX-like operating systems.
|
|
|
|
The Scheme interpreter is written in ~5,000 LOC of simple C, and the C
|
|
compiler written in Scheme and these are mutual self-hosting. This
|
|
mes.c is now being simplified to be transpiled by M2-Planet[4].
|
|
|
|
Mes 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] --and test suite, just
|
|
enough to support a REPL and a C99 compiler: mescc.
|
|
|
|
Mes+MesCC can compile an only lightly patched TinyCC[8] 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 Guix for
|
|
i686-linux, x86_64-linux, armhf-linux and aarch64-linux.
|
|
|
|
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[9] -- John
|
|
McCarthy page 13, GNU Guix's source/binary packaging transparency and
|
|
Jeremiah Orians's stage0[10] ~500 byte self-hosting hex assembler.
|
|
|
|
We are very grateful to NLNet for sponsoring the Reduced Binary Seed
|
|
bootstrap[11] and the ARM port[12].

[*] 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-0.23.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.

** Core
|
|
*** Mes and Mes C Library can now be built with GCC 10.x.
|
|
** MesCC
|
|
*** The Mes C Library now supports an armhf-linux bootstrap.
|
|
*** MesCC now supports ARM.
|
|
*** mini.c library was split into _exit.c, and _write.c.
|
|
*** When building with GCC, -lgcc is now used.
|
|
*** MesCC now has it's own support library libmescc.a (-lmescc).
|
|
*** MesCC now requires mescc-tools-0.7.0 or later for ARM.
|
|
*** MesCC can be now built with nyacc-1.00.2:
|
|
note that nyacc-1.03.0 is not (backwards) compatible.
|
|
*** MesCC can be built with Guile 3.0.x:
|
|
See https://bugs.gnu.org/43831; use guild compile -O1 with Guile 3.0.x.
|
|
*** MesCC now raises SIGABRT on abort, if supported.
|
|
** Noteworthy bug fixes
|
|
*** unreadchar on EOF is now a no-op.
|
|
*** malloc now aligns the blocks it gives out to max_align_t.
