We are happy to announce the release of GNU Mes 0.26.
It's been only a month since the previous release mainly because most
this work has been waiting for 0.25 to be released. This release
represents 194 commits over one year by two people. This release brings
Guile module support and support for running Gash and Gash-Utils.
We are excited that the NLnet Foundation is sponsoring this work!
What's next?
Bringing the Full Source Bootstrap to NixOS. Remove indirect Guile
dependencies (via Gash and Gash-Utils) from the Mes bootstrap in Guix.
Support for bootstrapping gcc-4.6.4, and a Full Source Bootstrap for
armhf-linux, and riscv64-linux.
Enjoy!
* About
GNU Mes is a Scheme interpreter and C compiler for bootstrapping the
GNU System. It has helped to decimate the number and size of binary
seeds that were used in the bootstrap of GNU Guix 1.0. Recently,
version 0.24.2 has realized the first Full Source Bootstrap for Guix
<https://guix.gnu.org/en/blog/2023/the-full-source-bootstrap-building-from-source-all-the-way-down/>.
The final goal is to help create a full source bootstrap as part of
the bootstrappable builds effort <https://bootstrappable.org> for any
UNIX-like operating system.
Mes + MesCC + Mes C Library can build a bootstrappable TinyCC
<https://gitlab.com/janneke/tinycc> that is self-hosting. Using this
bootstrappable-tcc and the Mes C library we can build an ancient
version of the GNU tools 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 was inspired by The Maxwell Equations of Software: LISP-1.5 --
John McCarthy page 13, Guix's source/binary packaging transparency and
Jeremiah Orians's Stage0 <https://github.com/oriansj/stage0>, a
~500-byte self-hosting hex assembler.

[*] 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-0.26.tar.gz.sig
The signature should match the fingerprint of the following key:
pub rsa4096 2018-04-08 [SC]
1A85 8392 E331 EAFD B8C2 7FFB F3C1 A0D9 C1D6 5273
uid Jan (janneke) Nieuwenhuizen <janneke@gnu.org>
If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.
gpg --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
As a last resort to find the key, you can try the official GNU
keyring:
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
gpg --keyring gnu-keyring.gpg --verify mes-0.26.tar.gz.sig

Cool!
A naive question. :-) I was randomly roaming and I have seen, for
example, in file module/mescc/x86_64/as.scm:
--8<---------------cut here---------------start------------->8---
;; AMD
(define (x86_64:function-preamble info . rest)
`(("push___%rbp")
("mov____%rsp,%rbp")
("sub____$i32,%rbp" "%0x80")
,@(list-head
'(("mov____%rdi,0x8(%rbp)" "!0x10")
("mov____%rsi,0x8(%rbp)" "!0x18")
("mov____%rdx,0x8(%rbp)" "!0x20")
("mov____%rcx,0x8(%rbp)" "!0x28")
("mov____%r8,0x8(%rbp)" "!0x30")
("mov____%r9,0x8(%rbp)" "!0x38"))
(length (car rest)))))
;; traditional
(define (x86_64:function-preamble info . rest)
`(("push___%rbp")
("mov____%rsp,%rbp")))
--8<---------------cut here---------------end--------------->8---
And my question is: the procedure name is exactly the same therefore how
is the correct one picked?
Thanks for all this!
Cheers,
simon

This is big deal!! That looks like an important milestone on the
bootstrapping journey in Guix.
Well done!
