Subject: Mes 0.11 released
|
|
|
|
I am pleased to announce the release of Mes 0.11, representing 16
|
|
commits over 10 weeks. MesCC now compiles a less heavily patched
|
|
TinyCC into a mes-tcc that in turn passes 41/69 of mescc's C tests.
|
|
|
|
When mes-tcc passes all 69 tests, this almost-full-source-bootstrapped
|
|
version of TinyCC should be able to compile itself. An unpatched, GNU
|
|
Gcc-compiled tcc is known to compile GNU Gcc.
|
|
|
|
* 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 compiled by M2-Planet or 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 (mescc.mes).
|
|
|
|
MesCC can compile a modified TinyCC[8] that is close to being
|
|
self-hosting. A GNU Ccc-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=v0.11 -O mes-0.11.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 0.11 since 0.10
|
|
** MesCC
|
|
*** MesCC now compiles a mes-tcc that passes 41/69 of mescc's C tests.
|
|
*** MesCC's libc can now be compiled with tcc (syscall support: write).
|
|
*** MesCC now compiles a less-patched tcc: -214/+458 lines [WAS: -333/+747].
|
|
*** MesCC now supports empty for.
|
|
*** MesCC has been greatly refactored, 500/3000 lines have been removed.
|
|
*** MesCC now supports complex [struct] by value assign foo.bar, foo->bar, foo[bar].
|
|
*** MesCC now depends on Nyacc 0.82.4.
