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.
