Add mes and mescc-tools-extra

Browse source 
mescc-tools-extra contains two important tools:
- cp
- chmod

mes first builds itself from a mes 0.21 seed as used by guix, and then
builds a mes 0.22 and then mes 0.22 using that created mes 0.22.

It does /not/ use bootstrap.sh as we don't have a proper shell at this
point, it has been manually adapted for kaem.

Subject: on bootstrapping: introducing Mes
Date: Sun, 19 Jun 2016 13:08:02 +0200
Hi,
I have a minimal LISP-1.5-resembling interpreter in C that now can
also interpret itself
https://gitlab.com/janneke/mes
It was inspired by the seemingly often ignored bootstrapping question
made so painfully visible by GuixSD and by OriansJ with their self
hosting hex assembler project.
As a next step after a hex assembler I was thinking of getting Scheme up
and running and use that to create a tiny C compiler, probably using
PEG. For that I think we need define-syntax, which I had a peek at and
still scares the all-sorts-of-things out of me :-)
I searched for minimal Lisp/Scheme to get that going and found an
article called the Maxwell Equations of Software 1) with a pointer to
the 1962 LISP 1.5 paper by John McCarthy 2).
First I `implemented' Mes/LISP-1.5: the bottom half of page 13 and the
necessary helper procedures defined on pages 8-12 using Guile, removing
all but the primitives needed to run LISP-1.5/Mes (I think): car, cdr,
cond, cons, define, eq?, '()/nil, null?, pair? and quote. I cheated
with read, and with display and newline for debugging.
Then I translated the program into C and got rid of read by using
getchar/ungetchar.
It's been great fun and now I'm kind of stuck a bit at the point of
implementing macros. I have a simplistic version in C but want to
remove that again --I like the idea of having the absolute minimal LISP
interpreter in C-- and only introduce macros after having bootstrapped
into the LISP/Mes domain.
Greetings,
Jan

Subject: Mes 0.10 released
I am pleased to announce the release of Mes 0.10, representing 82
commits over 6 weeks. Mescc now compiles a bootstrappable-modified
TinyCC into a mes-tcc that in turn can successfully compile a trivial
C program.
* About
Mes[0] aims to create full source bootstrapping for GuixSD[1] as
part of the bootstrappable builds[2] project.
It currently consists of a mutual self-hosting [close to Guile-]
Scheme interpreter prototype in C and a Nyacc-based C compiler in
[Guile] Scheme. This C prototype will be rewritten in stage0[3]
M1 assembly (or possibly stage2 slow-LISP, or ...).
The Scheme interpreter prototype (mes.c) has a Garbage Collector,
a library of loadable Scheme modules-- notably Dominique Boucher's
LALR[4], Pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt
Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely
enough to support a simple REPL (repl.mes) and simple C-compiler
(mescc.mes).
The simple C compiler can compile a modified TinyCC[8] that is
starting to work! A gcc-compiled tcc is known[9] to compile GCC.
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 ~300 byte self-hosting
hex assembler.
* Download
git clone https://gitlab.com/janneke/mes
wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=v0.10 -O mes-0.10.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

Subject: Mes 0.12 released
I am pleased to announce the release of Mes 0.12, representing 120
commits over 20 weeks. MesCC is prototyped running on Guile and can
now run on Mes. Performance of Mes running MesCC has been improved by
a factor of 100; mes.c (~3000 LOC) now compiles in ~4min. Many fixes
and enhancements make that now also TinyCC parses (~1.5h) and compiles
(~20min) with Mes+MesCC (Guile+MesCC takes ~2min).
Special thanks go to Ricardo Wurmus for sharing the recursive macro
expand perspective and starting work on that, to Han-Wen Nienhuys for
his sharp `Ah, so you skipped SICP chapter 3' remark and to rain1 for
their continuous help on #bootstrapping and their `let's only expand
global variables' insight.

Subject: Mes 0.15 released
I am pleased to announce the release of Mes 0.15, representing 45
commits over 3 weeks. The GNU toolchain is getting bootstrapped!
As of 0.14, Mes+MesCC compiles a self-hosting TinyCC. Using the 0.15
Mes C library, this TinyCC can build the GNU tools triplet:
binutils-2.14, gcc-2.95.3, glibc-2.2.5.
This means that we can build a GNU toolchain that depends only on a
critical 1MB ASCII M1 seed. GuixSD currently uses a ~250MB binary
seed to build gcc.
Next targets are: upstream the Mes bootstrap to GuixSD, build a
Gcc-4.7 and Glibc-2.23, bootstrap utilities like bison, flex, grep,
sed..., replace GuixSD's bootstrap for x86 and reduce the 1MB ASCII M1
seed to ~5000 LOC/~100KB of M2 source, which is a restricted subset of
C.
Packages are available from Guix's wip-bootstrap branch.

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

* 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.

<#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.

Subject: GNU Mes 0.19 released
<#secure method=pgpmime mode=sign>
We are pleased to announce the release of GNU Mes 0.19, representing
100 commits over 10 weeks.
Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
a GNU/Linux system without binary GNU toolchain or equivalent) and work
is ongoing to audit and verify this bootstrap path in NixOS.
This release introduces strings as byte-array, hash-tables and native
structs. While that does increase the footprint somewhat, it fixes
our performance issue; tinycc is now compiled in ~8min (WAS: ~1h30).
Next targets:
- translate mes.c into unsnarfed mes.M2
- use Gash to remove bash, coreutils&co, grep, sed, tar from the Guix
bootstrap binaries
- replace the NixOS bootstrap
- use dietlibc, uClibc, ... for bootstrapping GNU (bash, binutils,
gcc, tar) and remove Mes C lib+gnu?
- bootstrap gcc-3.x or 4.x directly, drop initial gcc-2.95.3 target?
- have M1+hex2 create gcc/tcc-usable object files? archives?
- Debian?
- ARM, the Hurd?
Packages are available from Guix's core-updates branch.

Subject: GNU Mes 0.20 released
<#secure method=pgpmime mode=sign>
We are pleased to announce the release of GNU Mes 0.20, representing
147 commits over 38 weeks.
Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
a GNU/Linux system without binary GNU toolchain or equivalent). It
should land in Guix master any day now: a big thank you to everyone who
helped, notably Ludovic and Mark.
This release is a step towards the upcoming Scheme-only bootstrap and
bringing Mes into NixOS and Debian. This effort is now sponsored by
NLnet[12].
Next targets:
- ARM support
- Reduced Binary Seed bootstrap for ARM
- Scheme-only bootstrap: use Guile and Gash to remove bash,
coreutils&co, grep, sed, etc. from the Guix bootstrap binaries
- mes-m2: port Mes.c to M2-Planet
- Introduce Reduced Binaries Seed bootstrap to NixOS
- Debian?
- Hurd
Packages are available in Guix master.

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 Guix 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.

Subject: GNU Mes 0.21 released
<#secure method=pgpmime mode=sign>
We are pleased to announce the release of GNU Mes 0.21, representing
54 commits over 10 weeks.
Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
a GNU/Linux system without binary GNU toolchain or equivalent). See
https://guix.gnu.org/blog/2019/guix-reduces-bootstrap-seed-by-50/
This release supports a Scheme-only bootstrap: Mes can now be built with
Gash and the experimental Gash Core Utils instead of using GNU Awk, GNU
Bash, the GNU Core Utilities, GNU Grep, GNU Gzip, GNU Make, GNU SED, and
GNU Tar. Also, the Mes C Library now supports bootstrapping those.
Finally, this release brings Mes as a package to Debian GNU/Linux.
We are excited that the Nlnet Foundation[12] is now sponsoring this
work!
Next targets:
- Introduce the Reduced Binaries Seed bootstrap to NixOS (Debian,
Gentoo, ...?)
- Scheme-only bootstrap: use Guile, Gash and Gash Core Utils to remove
awk, bash, core utilities, grep, gzip, make, sed, tar, etc. from the
Guix bootstrap binaries
- ARM support
- Full Source Bootstrap: compile Mes.c using M2-Planet
- Reduced Binary Seed bootstrap for ARM
- the Hurd
Packages are available in Guix master.

Subject: GNU Mes 0.22 released
<#secure method=pgpmime mode=sign>
We are pleased to announce the release of GNU Mes 0.22, representing
57 commits over 8 weeks.
Mes can now be built reproducibly by mes+mescc or guile+mescc accross
distributions such as GNU Guix, Debian GNU/Linux and NixOS. Also, many
build issues were fixed. A big thank you to reproducible-builds.org,
Vagrant Cascadian, Jelle van der Waa, Hannes Mehnert and David Terry!
Mes now runs on the Hurd--mescc does not run yet, many system calls are
missing, especially fork/exec--and initial scaffolding support for
creating FreeBSD binaries was added.
This release better supports bringing the Scheme-only bootstrap to Guix:
it no longer requires an update to the Guix bootstrap seed.
The Scheme-only bootstrap means that Mes can now be built with Gash and
the experimental Gash Core Utils instead of using GNU Awk, GNU Bash, the
GNU Core Utilities, GNU Grep, GNU Gzip, GNU Make, GNU Sed, and GNU Tar.
Also, the Mes C Library now supports bootstrapping those.
We are excited that the Nlnet Foundation[12] is now sponsoring this
work!
Next targets:
- Introduce the Reduced Binaries Seed bootstrap to NixOS (Debian,
Arch, Gentoo, ...?)
- Merge the Scheme-only bootstrap, the wip-bootstrap branch (using
Guile, Gash and Gash Core Utils to remove awk, bash, core utilities,
grep, gzip, make, sed, tar, etc. from the Guix bootstrap binaries)
into Guix core-updates.
- ARM support
- Full Source Bootstrap: compile Mes.c using M2-Planet
- Add full Guile module support
- Reduced Binary Seed bootstrap for ARM
- Support mescc on the Hurd (fork/exec, ...)
Packages are available in Guix master; the cross-distro reproducible
is built using
guix build --system=i686-linux mes-rb5

*** Mes now builds reproducibly with MesCC, cross distribution
Using --with-bootstrap on x86, a bin/mes-mescc is compiled with
mes+mescc, that shall have sha256sum
9e0bcb1633c58e7bc415f6ea27cee7951d6b0658e13cdc147e992b31a14625fb bin/mes-mescc
This has been verified on GNU Guix, Debian GNU/Linux and NixOS.
*** Mes now builds reproducibly with Guile+MesCC vs Mes+MesCC.
*** Mes now builds reproducibly with Tiny CC-built MesCC.
*** configure now respects the user's CFLAGS, CPPFLAGS and LDFLAGS.
*** Mes now supports mescc-tools 0.5.2 next to 0.6.1.
This allows introducing the Scheme-only bootstrap without updating or
adding new bootstrap binary seeds into GNU Guix.
*** Mes now runs when configured --with-courage on the Hurd:
GNU debian 0.9 GNU-Mach 1.8+git20170609-486/Hurd-0.9 i686-AT386 GNU
Note that mescc does not run; fork and exec are not yet implemented.
*** Mes now configures --with-courage on x86-FreeBSD 12.1
The initial ELF scaffold tests: exit-42.S, 0exit-42.hex2,
body-exit-42.hex2, hello-mes.S, 0hello-mes.hex2, body-hello-mes.hex2
pass.
*** configure now has a --with-bootstrap option.
This adds the reproducible bootstrap build of bin/mes-mescc, using
mes+mescc.
*** configure prefers $CC over gcc; tcc over gcc, gcc over cc.
*** Mes now prints an error when attempting to read a file that does not exist.
*** Mes no longer depends on GIT.
** Noteworthy bug fixes
*** Several annoying build problems were fixed, for non-Guix systems.
*** A bug with buffered-read was fixed.
This means that bash-2.05 can now build glibc-2.2.5; notably it now
successfully executes make-syscall.sh.
*** A bug with execlp, execvp for file names containing a slash was fixed.
This should allow make-3.80 running scripts that have "#! ./move-if-change".

Subject: on bootstrapping: first Mes 0.3 released
I am pleased to announce the first release of Mes: 0.3, representing
152 commits over 3 months since the second status report[1].
* About
Mes aims to create an entirely source-based bootstrapping path. The
target is to [have GuixSD] boostrap from a minimal, easily inspectable
binary --that should be readable as source-- into something close to
R6RS Scheme.
As bootstrapping is presumably easiest and probably most fun with
Scheme, the next step for Mes is mescc: a C compiler/linker to
boostrap into GNU Gcc and GNU Guile, possibly via Tiny-CC.
It currently has an interpreter written in C (mes) with Garbage
Collector (Jam Scraper), a library of loadable Scheme modules with
test suite just barely enough to support a simple REPL (repl.mes)
and a proof-of-concept c-compiler (mescc.mes) that produces an elf
from the simplest of C files.
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[2]

* Download
git clone https://gitlab.com/janneke/mes
wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=v0.3 -O mes-0.3.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
* Changes in 0.3 since 0.2
** Core
*** Number-based rather than pointer-based cells.
*** Garbage collector aka Jam scraper.
A variant on SICP's stop and copy Garbage Collector (Jam Scraper?)
algorithm has been implemented.
*** The reader has been moved to Scheme.
** Language
*** Simple loadable modules.
*** Srfi-9 and match use handwritten syntax-rules (mes-use-module (mes syntax)).
*** Optional syntax-case using psyntax (mes-use-module (mes psyntax)).
** Noteworthy bug fixes
*** Srfi-0 has been fixed.
* Changes in 0.2 since 0.1
** Core
*** Names of symbols and strings are list of characters [WAS: c-string].
*** Sc-expand from pre-R6RS's psyntax has been integrated.
*** Undefined variable error now shows the name of the undefined variable.
*** There is now only one SCM type for builtin functions.
*** Macro expansion has been cleaned-up.
** Language
*** Mes now provides a subset of R6RS.
*** Mes now provides syntax-case.
*** Mes now provides `load'.
** Noteworthy bug fixes
*** Using values as second parameter of builtin function yields first value.
*** Quoted internals (e.g. 'if 'lambda) are now symbols.
*** Syntax error now exits.
*** Make+Bash voodoo has been replaced by build-aux/mes-snarf.scm.
*** Apply now accepts multiple list arguments.
*** Apply of character, inernal, number, string is an error.
*** Quasisyntax reading
* Changes in 0.1 (since progress report #2)
** Core
*** expand_macro is now a separate function.
*** A smaller core can now compiled using BOOT=1.
The smaller core does not provide define, define-macro, or quasiquote;
these are provided from a Scheme version of implemented eval/apply.
** Language
*** Mes now provides a subset of R5RS.
*** Mes now provides let-syntax.
*** Mes now provides match.
*** Mes now provides quasisyntax, unsyntax and unsyntax-splicing.
** User interface
*** Mes now provides a REPL, run:
scripts/repl.mes
*** Mes compiler can be run as a script:
scripts/mescc.mes doc/examples/main.c
*** Macro expansion can be inspected in the REPL, e.g.:
,expand (and 0 1)
** Noteworthy bug fixes
*** Performance: scripts/mescc.mes now takes 2s to compile main.c (was 1'20").
*** Symbols are now truly unique.
* '(), #t, #f are no longer symbols.

Subject: Mes 0.4 released
I am pleased to announce the release of Mes 0.4, representing 115
commits over barely two weeks. It now runs Nyacc and PEG and has much
reduced core.
* About
Mes aims to create an entirely source-based bootstrapping path. The
target is to [have GuixSD] boostrap from a minimal, easily inspectable
binary --that should be readable as source-- into something close to
R6RS Scheme.
As bootstrapping is presumably easiest and probably most fun with

boostrap into GNU Gcc and GNU Guile, possibly via Tiny-CC.
It currently has an interpreter written in C (mes) with Garbage
Collector (Jam Scraper), a library of loadable Scheme modules--
notably Dominique Boucher's LALR[1], Pre-R6RS portable

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
* Changes in 0.4 since 0.3
** Core
*** Improved performance.
Macros are now memoized; after expansion and before eval'ing the
expanded form, their input s-expression is replaced by the expansion.
This yields a nice performance improvement which finally allowed
moving all non-essential bits from the C-core into Scheme...including
the reader. The Scheme reader is much, much slower than the previous
C version, making Mes--again-- feel slow. Think of that as a feature.
*** Bootstrap with minimal reader in C.
The C-reader needs only support reading of words and lists
(s-expressions), line-comments to read the initial Scheme reader which
then takes over and handles reading of quoting, characters, strings,
block-comments.
*** Reduced size.
Total C size: ~1500LOC. The main Mes evaluator is now ~1000LOC
including cell creation and garbage collector. This code is able to
execute a Scheme program that has been loaded into memory. Another
~500LOC is spent to load a minimal Scheme program and to dump it, to
provide a small posix interface, math functions and do some error
reporting.
*** Programs can be dumped and loaded using --dump and --load.
** Language
*** Minimal syntactic exception support for Nyacc.
*** Minimal syntactic fluids support for Nyacc.
*** Keywords are now supported.
*** Cond now supports =>.
*** Guile's optargs: lambda* and define* are now supported.
*** #;-comments are now supported.
*** Non-nested #| |#-comments are now supported.
*** Quasisyntax is now supported.
*** R7RS syntax-rules with custom ellipsis, with-ellipsis are now supported.
*** 9 new [partial] modules
(mes fluids), (mes nyacc), (mes optargs), (mes pmatch), (mes peg),
(srfi srfi-13), (srfi srfi-9-psyntax), (srfi srfi-26), (srfi srfi-43),
(rnrs arithmetic bitwise), (sxml xpath)
*** 36 new functions
1+, 1-, abs, and=>, append-reverse, ash, char<=?, char<?, char>=?,
char>?, even?, filter, delete, delq, vector-copy, fold, fold-right,
getenv, iota, keyword->symbol list-head, list-tail, negative?, odd?,
positive?, remove!, remove, string->number, string-copy,
string-prefix?, string=, string=?, symbol->keyword symbol-append,
symbol-prefix?, unless, write, zero?.
** Noteworthy bug fixes
*** Macros are now memoized.
*** An error is reported when using a wrong number of arguments with a call.
*** Cond now evaluates its test clauses only once.
*** Append can also handle one argument.
*** For-each now supports 2 list arguments.
*** Map now supports 3 list arguments.
*** Backslash in string is supported.
*** Closure is not a pair.
*** All standard characters are supported.
*** Mescc now also runs in Guile.

Subject: on bootstrapping: 2nd status report on Mes
Date: Sun, 25 Sep 2016 13:52:11 +0200
Hi!
In June I announced[0] Mes as a project that seeks to reduce the size of/
dependency on bootstrap binaries, esp. for a system like GuixSD
The strategy was to create a minimal trusted binary (prototyped in C but
eventually to be hand-crafted in assembly/hex) that interpets a minimal
LISP. Then using this minimal but already convenient LISP, extend it
into Scheme and write a tiny C compiler/linker.
Last time I had a minimal LISP-1.5-resembling interpreter in 900 lines
of C that could interpret itself and an extension layer written in LISP
providing a minimal Scheme environment. I was stuck on adding macros in
LISP and had a broken macro implentation in C that I wanted to remove.
Also I hoped to greatly reduce the size of the C part.
New status[1]
* Provide Scheme primitives directly in 1400 lines of C
* Remove LISP-1.5 staging
* closures clue-bat, fixing bugs in begin, lambda, lexical
scoping etc. ... learned a lot!
* quasiquote, unquote, unquote-splicing (in C, too slow in Scheme)
* define-macro (in C)
* define-syntax, syntax-rules (in Scheme, using define-macro)
* all primitives needed to run LALR (strings, vectors, records,
some srfi bits; mostly in Scheme)
* test suite with 97 tests that run with Mes and also with Guile
* minimal and partial ANSI C parser for hello world
* minimal and simplistic 32 bit elf c-ast->elf generator
Mes can now create a running 32-bit elf binary from this hello
world C source with a simplistic for loop
int main ()
{
int i;
puts ("Hi Mes!\n");
for (i = 0; i < 4; ++i)
puts (" Hello, world!\n");
return 1;
}
It takes Mes 1'20" to compile this program, Guile takes 0.5 seconds.
* cannot get psyntax.pp hooked-up or running
* do not understand syntax stuff [well enough] to implement in C
-> no let-syntax, no MATCH
-> no syntax-case, no PEG parser
In theory the bootstrapping problem I set out to solve seems to be
cracked. The remaining problem is reduced to `just work':
implementing a minimal C compiler in Scheme. Questions here: I'm not
convinced yet that this is a meaningful project...aaand I really not
want to tackle this without having MATCH, which Mes does not have yet.
Of the possible directions that I see
0 write the C compiler in Scheme without match
1 rewrite match without let-syntax
2 grok+write let-syntax/syntax-case using define-macro, some bits in C
3 run and hook-up psyntax.pp...BUT that would probably require:
4 address performance problem, possibly by
5 rewrite Mes into a VM-based solution
none I find really attractive. Option 5, a VM is proven to work but
that's quite a change of direction. Looking at other VM-based projects
(e.g. GNU Epsilon[2]) I fear that this must result in a much larger code
base in C, throwing out the minimal trusted binary idea. The other
puzzles and work 0, 2 or 3 still need to be done.
However, diving into syntax-macro or eval work (2 or 3) most probably
needs the performance issue addressed. And if it turns out that a big
VM solution is needed, that may still invalidate this project after
having done even more work.
Help! :-) Ideas?
Greetings,
Jan

Subject: wip-bootstrap updated
I've updated the wip-bootstrap branch[0] for Mes[1] 0.13. It has new
mes-boot and tcc-boot packages. mes-boot is a bootstrap version of
Mes; it only depends on mescc-tools and a previously compiled mes.M1
seed. Likewise, tcc-boot depends on a precompiled tcc-seed. Also,
tcc-boot uses a heavily patched version of the tcc sources.
Mes 0.13 is the first release that can bootstrap a fairly functional
tcc-boot. This bootstrapped tcc passes 67/68 C tests that were created
for MesCC. It can compile a version if itself where float, long long
and bitfield are patched out...but linking fails. This amazing
compiler can now be played with by doing something like
--8<---------------cut here---------------start------------->8---
git checkout wip-bootstrap
make
./pre-inst-env guix build tcc-boot # may take ~2h
./pre-inst-env guix environment --ad-hoc tcc-boot
mes-tcc --help #duck and run
--8<---------------cut here---------------end--------------->8---
The next big effort will be to make this mes-tcc fully functional and
integrate this with GuixSD. To give you a taste of that,
here's latest bug I'm currently looking at (pretty printed comments
are only added when Guile runs MesCC, the problem is in LEA)

We also need to remove some shortcuts that we took, most notably:
mes-seed[3]. This seed consists of 1MB of M1 code. mes.M1 is
produced by compiling mes.c using MesCC, the C compiler written in
(Guile) Scheme that comes with Mes. Although that's really terrible,
it's probably a big step forward: currently GuixSD uses ~250MB of
binary seed: the bootstrap binaries.
The plan is to replace the mes.M1 seed with mes.M2 and compile this
new mes.M2 seed using the brand new M2-Planet[2]. M2 is basically
simple C with structs, without preprocessor. This will reduce the
seed size by a factor of 10 while making it much more readable.

with or without modifying it, either commercially or noncommercially.
Secondarily, this License preserves for the author and publisher a way
to get credit for their work, while not being considered responsible
for modifications made by others.
This License is a kind of ``copyleft'', which means that derivative
works of the document must themselves be free in the same sense. It
complements the GNU General Public License, which is a copyleft
license designed for free software.
We have designed this License in order to use it for manuals for free
software, because free software needs free documentation: a free
program should come with manuals providing the same freedoms that the
software does. But this License is not limited to software manuals;
it can be used for any textual work, regardless of subject matter or
whether it is published as a printed book. We recommend this License
principally for works whose purpose is instruction or reference.
@item
APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work, in any medium, that
contains a notice placed by the copyright holder saying it can be
distributed under the terms of this License. Such a notice grants a
world-wide, royalty-free license, unlimited in duration, to use that
work under the conditions stated herein. The ``Document'', below,
refers to any such manual or work. Any member of the public is a
licensee, and is addressed as ``you''. You accept the license if you
copy, modify or distribute the work in a way requiring permission
under copyright law.
A ``Modified Version'' of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with
modifications and/or translated into another language.
A ``Secondary Section'' is a named appendix or a front-matter section
of the Document that deals exclusively with the relationship of the
publishers or authors of the Document to the Document's overall
subject (or to related matters) and contains nothing that could fall
directly within that overall subject. (Thus, if the Document is in
part a textbook of mathematics, a Secondary Section may not explain
any mathematics.) The relationship could be a matter of historical
connection with the subject or with related matters, or of legal,
commercial, philosophical, ethical or political position regarding
them.
The ``Invariant Sections'' are certain Secondary Sections whose titles
are designated, as being those of Invariant Sections, in the notice
that says that the Document is released under this License. If a
section does not fit the above definition of Secondary then it is not
allowed to be designated as Invariant. The Document may contain zero
Invariant Sections. If the Document does not identify any Invariant
Sections then there are none.
The ``Cover Texts'' are certain short passages of text that are listed,
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
the Document is released under this License. A Front-Cover Text may
be at most 5 words, and a Back-Cover Text may be at most 25 words.
A ``Transparent'' copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the
general public, that is suitable for revising the document
straightforwardly with generic text editors or (for images composed of
pixels) generic paint programs or (for drawings) some widely available
drawing editor, and that is suitable for input to text formatters or
for automatic translation to a variety of formats suitable for input
to text formatters. A copy made in an otherwise Transparent file
format whose markup, or absence of markup, has been arranged to thwart
or discourage subsequent modification by readers is not Transparent.
An image format is not Transparent if used for any substantial amount
of text. A copy that is not ``Transparent'' is called ``Opaque''.
Examples of suitable formats for Transparent copies include plain
ASCII without markup, Texinfo input format, La@TeX{} input
format, SGML or XML using a publicly available
DTD, and standard-conforming simple HTML,
PostScript or PDF designed for human modification. Examples
of transparent image formats include PNG, XCF and
JPG. Opaque formats include proprietary formats that can be
read and edited only by proprietary word processors, SGML or
XML for which the DTD and/or processing tools are
not generally available, and the machine-generated HTML,
PostScript or PDF produced by some word processors for
output purposes only.
The ``Title Page'' means, for a printed book, the title page itself,
plus such following pages as are needed to hold, legibly, the material
this License requires to appear in the title page. For works in
formats which do not have any title page as such, ``Title Page'' means
the text near the most prominent appearance of the work's title,
preceding the beginning of the body of the text.
The ``publisher'' means any person or entity that distributes copies
of the Document to the public.
A section ``Entitled XYZ'' means a named subunit of the Document whose
title either is precisely XYZ or contains XYZ in parentheses following
text that translates XYZ in another language. (Here XYZ stands for a
specific section name mentioned below, such as ``Acknowledgements'',
``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
of such a section when you modify the Document means that it remains a
section ``Entitled XYZ'' according to this definition.
The Document may include Warranty Disclaimers next to the notice which
states that this License applies to the Document. These Warranty
Disclaimers are considered to be included by reference in this
License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and has
no effect on the meaning of this License.
@item
VERBATIM COPYING
You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License applies
to the Document are reproduced in all copies, and that you add no other
conditions whatsoever to those of this License. You may not use
technical measures to obstruct or control the reading or further
copying of the copies you make or distribute. However, you may accept
compensation in exchange for copies. If you distribute a large enough
number of copies you must also follow the conditions in section 3.
You may also lend copies, under the same conditions stated above, and
you may publicly display copies.
@item
COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have
printed covers) of the Document, numbering more than 100, and the
Document's license notice requires Cover Texts, you must enclose the
copies in covers that carry, clearly and legibly, all these Cover
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
the back cover. Both covers must also clearly and legibly identify
you as the publisher of these copies. The front cover must present
the full title with all words of the title equally prominent and
visible. You may add other material on the covers in addition.
Copying with changes limited to the covers, as long as they preserve
the title of the Document and satisfy these conditions, can be treated
as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto adjacent
pages.
If you publish or distribute Opaque copies of the Document numbering
more than 100, you must either include a machine-readable Transparent
copy along with each Opaque copy, or state in or with each Opaque copy
a computer-network location from which the general network-using
public has access to download using public-standard network protocols
a complete Transparent copy of the Document, free of added material.
If you use the latter option, you must take reasonably prudent steps,
when you begin distribution of Opaque copies in quantity, to ensure
that this Transparent copy will remain thus accessible at the stated
location until at least one year after the last time you distribute an
Opaque copy (directly or through your agents or retailers) of that
edition to the public.
It is requested, but not required, that you contact the authors of the
Document well before redistributing any large number of copies, to give
them a chance to provide you with an updated version of the Document.
@item
MODIFICATIONS
You may copy and distribute a Modified Version of the Document under
the conditions of sections 2 and 3 above, provided that you release
the Modified Version under precisely this License, with the Modified
Version filling the role of the Document, thus licensing distribution
and modification of the Modified Version to whoever possesses a copy
of it. In addition, you must do these things in the Modified Version:
@enumerate A
@item
Use in the Title Page (and on the covers, if any) a title distinct
from that of the Document, and from those of previous versions
(which should, if there were any, be listed in the History section
of the Document). You may use the same title as a previous version
if the original publisher of that version gives permission.
@item
List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
@item
State on the Title page the name of the publisher of the
Modified Version, as the publisher.
@item
Preserve all the copyright notices of the Document.
@item
Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
@item
Include, immediately after the copyright notices, a license notice
giving the public permission to use the Modified Version under the
terms of this License, in the form shown in the Addendum below.
@item
Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document's license notice.
@item
Include an unaltered copy of this License.
@item
Preserve the section Entitled ``History'', Preserve its Title, and add
to it an item stating at least the title, year, new authors, and
publisher of the Modified Version as given on the Title Page. If
there is no section Entitled ``History'' in the Document, create one
stating the title, year, authors, and publisher of the Document as
given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.
@item
Preserve the network location, if any, given in the Document for
public access to a Transparent copy of the Document, and likewise
the network locations given in the Document for previous versions
it was based on. These may be placed in the ``History'' section.
You may omit a network location for a work that was published at
least four years before the Document itself, or if the original
publisher of the version it refers to gives permission.
@item
For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
the Title of the section, and preserve in the section all the
substance and tone of each of the contributor acknowledgements and/or
dedications given therein.
@item
Preserve all the Invariant Sections of the Document,
unaltered in their text and in their titles. Section numbers
or the equivalent are not considered part of the section titles.
@item
Delete any section Entitled ``Endorsements''. Such a section
may not be included in the Modified Version.
@item
Do not retitle any existing section to be Entitled ``Endorsements'' or
to conflict in title with any Invariant Section.
@item
Preserve any Warranty Disclaimers.
@end enumerate
If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no material
copied from the Document, you may at your option designate some or all
of these sections as invariant. To do this, add their titles to the
list of Invariant Sections in the Modified Version's license notice.
These titles must be distinct from any other section titles.
You may add a section Entitled ``Endorsements'', provided it contains
nothing but endorsements of your Modified Version by various
parties---for example, statements of peer review or that the text has
been approved by an organization as the authoritative definition of a
standard.
You may add a passage of up to five words as a Front-Cover Text, and a
passage of up to 25 words as a Back-Cover Text, to the end of the list
of Cover Texts in the Modified Version. Only one passage of
Front-Cover Text and one of Back-Cover Text may be added by (or
through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or
by arrangement made by the same entity you are acting on behalf of,
you may not add another; but you may replace the old one, on explicit
permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License
give permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.
@item
COMBINING DOCUMENTS
You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified
versions, provided that you include in the combination all of the
Invariant Sections of all of the original documents, unmodified, and
list them all as Invariant Sections of your combined work in its
license notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by
adding at the end of it, in parentheses, the name of the original
author or publisher of that section if known, or else a unique number.
Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled ``History''
in the various original documents, forming one section Entitled
``History''; likewise combine any sections Entitled ``Acknowledgements'',
and any sections Entitled ``Dedications''. You must delete all
sections Entitled ``Endorsements.''
@item
COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents
released under this License, and replace the individual copies of this
License in the various documents with a single copy that is included in
the collection, provided that you follow the rules of this License for
verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute
it individually under this License, provided you insert a copy of this
License into the extracted document, and follow this License in all
other respects regarding verbatim copying of that document.
@item
AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate
and independent documents or works, in or on a volume of a storage or
distribution medium, is called an ``aggregate'' if the copyright
resulting from the compilation is not used to limit the legal rights
of the compilation's users beyond what the individual works permit.
When the Document is included in an aggregate, this License does not
apply to the other works in the aggregate which are not themselves
derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document's Cover Texts may be placed on
covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.
@item
TRANSLATION
Translation is considered a kind of modification, so you may
distribute translations of the Document under the terms of section 4.
Replacing Invariant Sections with translations requires special
permission from their copyright holders, but you may include
translations of some or all Invariant Sections in addition to the
original versions of these Invariant Sections. You may include a
translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions
of those notices and disclaimers. In case of a disagreement between
the translation and the original version of this License or a notice
or disclaimer, the original version will prevail.
If a section in the Document is Entitled ``Acknowledgements'',
``Dedications'', or ``History'', the requirement (section 4) to Preserve
its Title (section 1) will typically require changing the actual
title.
@item
TERMINATION
You may not copy, modify, sublicense, or distribute the Document
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense, or distribute it is void, and
will automatically terminate your rights under this License.
However, if you cease all violation of this License, then your license
from a particular copyright holder is reinstated (a) provisionally,
unless and until the copyright holder explicitly and finally
terminates your license, and (b) permanently, if the copyright holder
fails to notify you of the violation by some reasonable means prior to
60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, receipt of a copy of some or all of the same material does
not give you any rights to use it.
@item
FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions
of the GNU Free Documentation License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns. See
@uref{http://www.gnu.org/copyleft/}.
Each version of the License is given a distinguishing version number.
If the Document specifies that a particular numbered version of this
License ``or any later version'' applies to it, you have the option of
following the terms and conditions either of that specified version or
of any later version that has been published (not as a draft) by the
Free Software Foundation. If the Document does not specify a version
number of this License, you may choose any version ever published (not
as a draft) by the Free Software Foundation. If the Document
specifies that a proxy can decide which future versions of this
License can be used, that proxy's public statement of acceptance of a
version permanently authorizes you to choose that version for the
Document.
@item
RELICENSING
``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
World Wide Web server that publishes copyrightable works and also
provides prominent facilities for anybody to edit those works. A
public wiki that anybody can edit is an example of such a server. A
``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
site means any set of copyrightable works thus published on the MMC
site.
``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
license published by Creative Commons Corporation, a not-for-profit
corporation with a principal place of business in San Francisco,
California, as well as future copyleft versions of that license
published by that same organization.
``Incorporate'' means to publish or republish a Document, in whole or
in part, as part of another Document.
An MMC is ``eligible for relicensing'' if it is licensed under this
License, and if all works that were first published under this License
somewhere other than this MMC, and subsequently incorporated in whole
or in part into the MMC, (1) had no cover texts or invariant sections,
and (2) were thus incorporated prior to November 1, 2008.
The operator of an MMC Site may republish an MMC contained in the site
under CC-BY-SA on the same site at any time before August 1, 2009,
provided the MMC is eligible for relicensing.

@heading ADDENDUM: How to use this License for your documents
To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and
license notices just after the title page:
@smallexample
@group
Copyright (C) @var{year} @var{your name}.
Permission is granted to copy, distribute and/or modify this document
under the terms of the GNU Free Documentation License, Version 1.3
or any later version published by the Free Software Foundation;
with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
Texts. A copy of the license is included in the section entitled ``GNU
Free Documentation License''.
@end group
@end smallexample
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
replace the ``with@dots{}Texts.''@: line with this:
@smallexample
@group
with the Invariant Sections being @var{list their titles}, with
the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
being @var{list}.
@end group
@end smallexample
If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.
If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of
free software license, such as the GNU General Public License,
to permit their use in free software.
