|
||||
|
||||
* Full source bootstrapping
|
||||
|
||||
** R6RS-like scheme interpreter
|
||||
This first part is prototyped in C by the mes.c core and Scheme
|
||||
bootstrap code in module/. Of course, while mes.c is pretty small it
|
||||
cannot serve as a full source solution.
|
||||
|
||||
The initial idea was to have the minimal core support LISP-1.5 (or
|
||||
something very close to that as a tribute to John McCarthy) and extend
|
||||
eval/apply from LISP-1.5 source with define, define-macro etc. and
|
||||
metamorphose into R6RS. It seemed to work but performance of the
|
||||
LISP-intepreted RRS was so bad (~1000x slower than initial LISP-1.5)
|
||||
that this track was abandoned after the initial ANNOUNCE.
|
||||
|
||||
The route changed, trying to strike a balance between core size and
|
||||
performance: still writing as much as possible in Scheme but having a
|
||||
mescc compiler that takes not more than some seconds to run.
|
||||
|
||||
Now that we have [[https://github.com/schemeway/lalr-scm][Dominique Boucher's LALR]], a [[https://www.cs.indiana.edu/chezscheme/syntax-case/old-psyntax.html][Pre-R6RS portable
|
||||
syntax-case]] with R7RS ellipsis, [[http://www.nongnu.org/nyacc/][Nyacc]] and [[https://www.gnu.org/software/guile/docs/master/guile.html/PEG-Parsing.html][Guile's PEG]] parsers, it's
|
||||
time to start doing something useful.
|
||||
|
||||
* Bugs
|
||||
** eval_apply/gc + Nyacc bug
|
||||
scripts/messc.mes intermittently exposes a bug in eval_apply/gc when
|
||||
Nyacc parses mes.c-sized source. Running
|
||||
|
||||
MES_MAX_ARENA=<another-size> scripts/mescc.mes
|
||||
|
||||
may [un]cover the bug. So there is probably some eval_apply-construct
|
||||
that Nyacc uses, possiblby indirectly via with-fluid, like (call/cc,
|
||||
call-with-current-continuation), that breaks when GC triggers at the
|
||||
wrong time.
|
||||
** mescc can only compile itself, it cannot compile tcc, gcc or guile
|
||||
** mes.mes cannot read sexps, only --dump's, mes.mes cannot --dump
|
||||
** Bootstrap binary mes is too big and opaque to be considered source
|
||||
68kB ELF binary which can be disassembled (objdump -d mes.mes).
|
||||
** Psyntax is too big and opaque to be considered source
|
||||
And needs a patched Guile-1.8 to [re]generate.
|
||||
** test/match.test ("nyacc-simple"): hygiene problem in match
|
||||
** The Scheme reader is very slow.

** Performance

Mes aims to create an entirely source-based bootstrapping path. The

target is to [have GuixSD] boostrap from a minimal, easily inspectable
|

R6RS Scheme.
|
||||
Mes aims to create full source bootstrapping for GuixSD: an entirely
|
||||
source-based bootstrap 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 consists of a mutual self-hosting [close to Guile-]
|
||||
Scheme interpreter prototype in C and a Nyacc-based C compiler in
|
||||
[Guile] Scheme.
|
||||
|
||||
It currently has an interpreter written in C (mes) with Garbage
|

C-compiler (mescc.mes) that produces an elf from the simplest of C

files.

Subject: Mes 0.5 released
|
||||
|
||||
I am pleased to announce the release of Mes 0.5, representing 250
|
||||
commits over 4 months. Mes is now self-hosting, or rather it features
|
||||
a mutual self-hosting Scheme interpreter and C compiler: mes.c and
|
||||
mescc; a Nyacc-based C compiler backend that also works separately
|
||||
with Guile.
|
||||
|
||||
* About
|
||||
|
||||
Mes aims to create full source bootstrapping for GuixSD: an
|
||||
entirely source-based bootstrap 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.
|
||||
|
||||
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.
|
||||
|
||||
The Scheme interpreter prototype (mes.c) has a Garbage Collector,
|
||||
a library of loadable Scheme modules-- notably Dominique Boucher's
|
||||
LALR[1], Pre-R6RS portable syntax-case[2] with R7RS ellipsis, Matt
